 现在参照图1B，所示的凸缘6 4包括向外延伸部1 O，例如弹性构件的阻挡构件1 2从该向外延伸部100以例如周向、径向、轴向以及其组合等的方式延伸。  Referring now to Figure 1B, the flange 64 as shown includes an outwardly extending portion 1 O, e.g., the blocking member is an elastic member 12 extending outwardly from the circumferential portion 100, for example, radial, axial, and its extending combinations and the like. 所示的阻挡构件102的端部104成形为具有倾斜面106和大致呈平形的面108的径向向外延伸的楔(使得阻挡构件102的径向宽度朝向端部104增加)。 Blocking member 102 shown in end 104 is shaped to have the inclined surface 106 and the wedge-shaped radial substantially flat surface 108 extending outward (radial width of the blocking member 102 toward end 104 increase). 类似地，例如轴向肋的大致楔形旋转锁定构件110从壳体14的内表面22径向向内延伸并且包括倾斜面112和大致呈平形的面114。 Similarly, for example, a substantially wedge-shaped axial ribs of the rotation lock member 110 extends and includes an inclined surface 112 and a substantially flat surface 114 formed from a radially inner surface 22 of the housing 14 inwardly. 在示出的改型中，倾斜面112构造成处于与倾斜面106相对的方向。 In the illustrated modification, the inclined surface 112 configured in a direction opposite the inclined surface 106. 尽管示出的端部104和旋转锁定构件110为大致楔形状，但可以使用多种形状，例如但不限于大致半球状、截头圆锥状、波状等。 While the illustrated end portion 104 and the rotary locking member 110 is substantially wedge-shaped, but various shapes may be used, such as but not limited to a substantially hemispherical, frusto-conical, corrugated and the like. 在一些实施方式中，旋转锁定构件110的轴向长度大于阻挡构件102和/或套筒64的轴向长度。 In some embodiments, the rotation lock member 110 is greater than the axial length of the block 102 and / or the axial length of the sleeve member 64. 在一些实施方式中，阻挡构件102的至少一部分构造成配合到旋转锁定构件110的至少一部分中，或旋转锁定构件110的至少一部分构造成配合到阻挡构件102的至少一部分中。 At least a portion of the structure in some embodiments, the barrier member 102 fit into the locking member 110 to rotate at least a part, or the rotary locking member 110 is configured to fit at least a portion of at least a portion of the barrier member 102. 例如，阻挡构件102可包括突起，该突起构造成配合在包括在旋转锁定构件110中的槽内。 For example, the barrier member 102 may comprise a protrusion which includes a slot configured to fit in the rotation lock member 110. 在一些实施方式中，阻挡构件102的至少一部分构造成配合到壳体14中的开口中。 At least a portion of the structure in some embodiments, the barrier member 102 to fit into the opening 14 in the housing. 切口116将向外延伸部100和端部104分隔开。 Notch 116 extending outward 100 and the end portion 104 spaced apart. 该切口116可以构造成至少与轴向锁定构件50的轴向横截面一样大，如将在下面进一步详细描述的。 The notch 116 can be configured to at least an axial cross-section of the axial locking member 50 as large, as will be described in further detail below.
 再次参照图1，套筒12包括多个轨道80-84以帮助例如在运动过程中对套筒12进行引导。  Referring again to FIG. 1, the sleeve 12 includes a plurality of tracks 80-84 to help, for example during movement of the guide sleeve 12. 在许多结构中，这些轨道构造成滑动地接纳壳体12的引导构件44。 In many structures, these tracks configured to slidably receive the guide member 44 of the housing 12. 因此，轨道80-84可以构造成具有与引导构件44相似的横截面形状，例如大致矩形、大致T形、大致扇形等。 Thus, the track 80-84 may be configured with similar cross-sectional shape of the guide member 44, e.g., a generally rectangular, generally T-shaped, a generally fan-like. 例如，示出的引导构件44和轨道80-84的横截面形状都呈大致梯形。 For example, the cross-sectional shape of the guide member 44 is shown and the track is substantially trapezoidal 80-84 were tested. 第一轨道80和第二轨道82大致平行于轴线18并且沿着套筒12从近端端部60至远端端部62延伸。 82 is substantially parallel to the first rail 80 and second rail to the axis 18 and 12 extending from the proximal end 60 to the distal end portion 62 along the sleeve. 分隔构件85沿着轨道80、82的长度的至少一部分或大部分分隔轨道80、82。 The partition member 85 along the length of the track 80, 82 separated by at least a part or most of the track 80,82. 分隔转移轨道84可以沿着套筒的长度定位在中部或中间区域并且相对于轴线18成一定角度(例如，不平行于轴线)，并且分隔转移轨道84可以打断分隔构件85并与第一轨道80和第二轨道82相交。 Transfer orbit separated along the length of the sleeve 84 may be positioned at the middle or intermediate region 18 with respect to the axis at an angle (e.g., not parallel to the axis), and the partition 84 may interrupt the transfer orbit and the partition member 85 with the first rail 80 and 82 intersect second track. 因此，转移轨道84可连接第一轨道80和第二轨道82以允许引导构件44在第一轨道80与第二轨道82之间转换，如将在下面进一步详细描述的。 Thus, the transfer rails 84 can be connected to the first rail 80 and second rail 82 to allow the guide member 44 between the first rail 80 and second rail 82 converts, as will be described in further detail below. 转移轨道84可为大致直的且非曲线的以便于沿着转移轨道84平滑行进。 Transfer orbit 84 may be generally straight and not curved to facilitate smooth travel along the transfer orbit 84. 在示出的示例中，转移轨道84的交点定位于套筒12的大约中部处，并且转移轨道84与第一轨道80的交点靠近转移轨道84与第二轨道82的交点。 In the illustrated example, the intersection of the transfer rail 84 is positioned on the sleeve 12 at approximately the middle of the track 84 and the intersection of the first transfer rail 80 adjacent the track 84 and the intersection of the second transfer rail 82. 在一些实施方式中，转移轨道84的长度可以通常大约与套筒12的横截面宽度(例如直径)的尺寸相同并且显著小于套筒12的长度。 In some embodiments, the length of the transfer rail 84 may be usually about 12 with the sleeve of cross-sectional width (e.g., diameter) of the same and significantly less than the length of the sleeve 12. 在示出的实施方式中，转移轨道84不构成第一轨道80或第二轨道82的一部分或为第一轨道80或第二轨道82的延续;相反，转移轨道84在每个轨道80、82上的在轨道80、82的起始与终端之间间隔开的点处(例如，在轨道80、82的中间或中部区域处)延伸远离两个其它轨道80、82。 In the embodiment illustrated, the transfer rails 84 do not form part of the first track or the second track 80 or 82 of the first track or the second track 80 of the continuation 82; instead, the transfer orbit 84 in each track 80, 82, point between the start and end rails 80, 82 spaced on (for example, in the middle of the track or at the central region 80, 82) extending away from the other two tracks 80,82.
 在一些实施方式中，第一轨道80包括转移轨道84远端的插入部86。  In some embodiments, the first track 80 includes an insertion portion 86 of the distal end of the transfer rail 84. 插入部86可构造成沿近端方向倾斜并且以第一轨道80与转移轨道84之间的交点处的大致呈平形的面88终止。 The insertion portion 86 may be configured to tilt the proximal direction and at the intersection of the first track 80 and the transfer orbit 84 between a substantially flat-shaped surface 88 terminates. 在某些实施方式中，插入部86有助于罩10的组装。 In certain embodiments, the insertion portion 10 of the assembly of the cover 86 contribute. 例如，在一个结构的组装过程中，套筒12穿过壳体14的近端端部34插入并且向远端移动。 For example, during assembly of a structure, the proximal end of the sleeve 12 through the housing 14 and insert 34 to move distally. 套筒12的远端端部62定位成使得引导构件44与第一轨道80的插入部86大致对准。 The distal end of the sleeve 12 of the guide member 62 is positioned such that the insertion portion 8644 of the first track 80 substantially aligned. 随着套筒向远端移动，引导构件44移上或拱上插入部86的倾斜部直到到达大致呈平形的面88，此时引导构件44可卡扣到第一轨道80的底部。 With the distal end of the sleeve to move the guide member 44 moves on the inclined portion or the insertion portion 86 until it reaches a substantially flat-shaped surface 88, when the guide member 44 can be snapped into the bottom of the first track 80 on the arch. 此后，呈平形的面88能够通过提供防止引导构件44沿着插入部86向远端移动的障碍物而抑制或防止罩10的拆开。 Thereafter, the form of a flat-shaped surface 88 can be prevented by providing the guide member 44 to inhibit or prevent the open cover 10 along the distal end of the insertion portion 86 to move the obstacle. 此外，呈平形的面88能够在套筒12缩回的过程中将引导构件44从第一轨道80导向到转移轨道84。 In addition, the form of a flat-shaped surface 88 can guide member 44 from the first guide rail 80 to the transfer rail 84 in the sleeve 12 is retracted in the process.
 罩10可有多种不同的尺寸以适于各种尺寸的针和多种类型的插入和/或抽取过程。  cover 10 can have a variety of different sizes to suit a variety of sizes and a variety of types of needle insertion and / or extraction process. 例如，罩10可构造成容适于在医疗(包括牙科)过程和在兽医过程中使用的针。 For example, the cover 10 may be configured in a container suitable for medical (including dental) procedure and the needle used in the veterinary procedure. 在一些实施方式中，罩1可具有至少约1mm和/或小于或等于约10mm的总长度，壳体14具有至少约6mm和/或小于或等于约20mm的直径，套筒12具有至少约3mm和/或小于或等于约18mm的直径。 In some embodiments, the cover 1 may have at least about 1mm and / or less than or equal to the total length of about 10mm, a housing 14 having at least about 6mm, and / or less than or equal to about 20mm in diameter, the sleeve 12 has at least about 3mm and / or less than or equal to about 18mm diameter. 在一些实施方式中，套筒12长于壳体14;在一些实施方式中，壳体14长于套筒12。 In some embodiments, the sleeve 12 is longer than the housing 14; in some embodiments, the housing 14 is longer than the sleeve 12. 罩10的一些示例包括具有约至少约5mm和/或等于或小于约50mm的长度的壳体14以及具有约至少约5mm和/或等于或小于约50mm的长度的套筒。 Some examples include a cover having about 10 to about at least 5mm and / or equal to or less than the length of about 50mm housing and having at least about 14 to about 5mm and / or equal to or less than the length of the sleeve is approximately 50mm. 其它结构包括具有至少约15mm和/或等于或小于约30mm的长度的壳体14以及具有约至少约1mm和/或小于或等于约40mm的长度的套筒。 Other structures include at least about 15mm and / or less than or equal to at least about 14 and about 1mm and / or less than or equal to the length of the sleeve has a length of about 40mm to about 30mm of housing. 套筒的一些实施方式构造成与具有至少约7和/或小于或等于约34的规格的针16—起使用。 Some embodiments of the sleeve is configured with at least about 7 and / or less than or equal to about 34 specifications of the needle from 16- use.
套筒12和壳体14的多种实施方式构造成提供各种可能的插入深度(通过针16的最大穿刺距离)。  the sleeve 12 and the various embodiments of the housing 14 is configured to provide a variety of possible insertion depth (maximum distance through the puncture needle 16). 这可以有助于解决例如各种过程之间一一如肌肉注射与皮下注射之间一一的不同的所需插入深度。 This can help to solve, for example eleven as intramuscular and subcutaneous injection of between eleven different desired insertion depth between the various processes. 在一些实施方式中，可能的插入深度由套筒12从完全伸出的位置(图1)行进到完全缩回的位置(图5)的距离确定。 In some embodiments, the depth of insertion may be by a sleeve 12 from a fully extended position (FIG. 1) to the travel position (FIG. 5) to determine the distance of the completely retracted. 在一些实施方式中，可能的插入深度为至少Imm和/或小于或等于约30mm。 In some embodiments, the possible insertion depth of at least Imm and / or less than or equal to about 30mm. 在其它结构中，可能的插入深度为至少3mm和/或小于或等于约70_。 In other constructions, the possible insertion depth of at least 3mm and / or less than or equal to about 70_. 在一些实施方式中，存在确定、设置、和/或改变可能的插入深度的机构。 In some embodiments, determining the existence of, setting, and / or may alter the depth of insertion mechanism. 例如，一些实施方式包括从壳体14的内表面22径向向内延伸的并且联接到轴向可动棘齿的止挡构件(未示出)，使得当达到所需的插入深度的级别时套筒12的近端端部60抵接止挡构件。 For example, some embodiments include 22 from the radially inner surface of the housing 14 extends inwardly and axially coupled to the ratchet movable stopper member (not shown), such that the desired insertion depth is reached when the level of the proximal end of the sleeve 12 abuts against the stopper member 60. 罩1包括标记，例如印在套筒12上的刻度，以显示针16的插入深度。 Housing 1 comprises a label, for example, printed on the sleeve 12 scale, to show the depth of insertion of the needle 16.
罩10以及其部件可以通过使用足以提供部件所需的形状的多种制造过程来形成。  10 and the cover member which may be sufficient to provide the use of a variety of shapes needed for the manufacturing process to form the member. 在一些实施方式中，一个或更多个部件通过模制过程制成，例如但不限于注塑模制、压缩模制、吹塑模制、传递模制或类似过程。 In some embodiments, one or more components formed by molding processes, such as, but not limited to, injection molding, compression molding, blow molding, transfer molding or similar processes. 在一些实施方式中，一个或更多个部件通过锻造、机械加工、铸造、冲压、挤压以及其组合等形成。 In some embodiments, one or more components formed by forging, machining, casting, pressing, extrusion, and combinations thereof.
在许多实施方式中，罩10由生物相容性材料构造。  In many embodiments, the cover 10 constructed of a biocompatible material. 在一些结构中，罩10的一个或更多个部件是塑料(例如聚醚醚铜)或金属(例如铝、钛、不锈钢等)。 In some configurations, one or more components of the cover 10 is a plastic (e.g., polyether ether copper) or a metal (e.g., aluminum, titanium, stainless steel, etc.). 在一些实施方式中，壳体14和/或套筒12由半透明的、不透明的、或其它光学失真(optically distortive)的材料构造，使得针16的一些部分(例如末端)或全部在其注射和/或抽吸之前、期间和/或之后对接受典型的注射和/或抽吸过程的患者而言是大致不可见的。 In some embodiments, the housing 14 and / or sleeve 12 made of translucent, opaque, or other optical distortions (optically distortive) constructed of a material, such that portions of needle 16 (e.g., terminal) or all of the injected before and / or suction and, during and / or after patients receiving typical injection and / or aspiration process is concerned is substantially invisible. 此外，除了通道26和壳体14中的用于轴向锁定构件50的开口48之外，壳体14和套筒12的某些示例通常完全封闭，例如没有狭槽、开口、或其它孔口以防止患者看见针16。 In addition to the axial passage 14 for the locking member 26 and the housing 50 outside the opening 48, the housing 14 and the sleeve 12 typically has some examples completely closed, for example, no slots, openings or other apertures in order to prevent patients from seeing the needle 16. 因此，在注射和/或抽吸过程中，针16的没有延伸经过通道26的任何部分都能够通过壳体14和套筒12从视野中遮挡，并且针16的延伸经过通道16的任何部分由于在药瓶内或患者体内而将被从视野中遮挡。 Therefore, the injection and / or aspiration procedure, a needle 16 does not extend through any portion of the channel 26 are blocked from view can 12 through the housing 14 and the sleeve 16 and extend through any portion of the needle 16 due to the passage in a vial or a patient's body and will be blocked from view. 当然，在某些情况下，当然，在一些情况下，除了其它因素以外，根据套筒12的远端端部62的具体形状以及针16插入到药瓶和/或患者的皮肤或组织中的角度，在注射和/或抽吸的整个过程中整个针16不会从视野中被完全遮挡。 Of course, in some cases, of course, in some cases, in addition to other factors, according to a distal end portion 62 of the sleeve 12 and the particular shape of the needle 16 is inserted into the vial and / or the patient's skin or tissue angle, and the whole process of the injection / aspiration or the entire needle 16 will not be completely blocked from view. 由于许多人在一看见针时就变得焦虑，因此上述特征可以显著地减轻患者和/或实施注射和/或抽吸的人(在自己注射的情况下也可是患者本人)的焦虑或恐惧以提供更舒适的整体治疗经历。 Since many people in the sight of the needle becomes anxious, so the above features can significantly reduce the patient and / or implementation of injection and / or aspiration of the people (in the case of self-injection, but also the patient's own) to anxiety or fear provide a more comfortable overall treatment experience.
在一些实施方式中，套筒12的远端端部62提供有压力感受器刺激特征。  In some embodiments, the distal end portion 62 of the sleeve 12 is provided with a baroreceptor stimulation characteristics. 已经发现在注射和/或抽吸的区域中的压力感受器神经的刺激与疼痛感受器神经的刺激产生竞争与干涉。 It has been found in the injection and / or aspiration of the region and stimulate nociceptors nerve stimulation baroreceptor nerve compete with interference. 在许多患者中，以这种方式进行的对压力感受器神经的刺激减弱了在针16的插入过程中对疼痛的感知。 In many patients, baroreceptor nerve stimulation in this manner weakened the perception of pain during insertion needle 16. 因此，在一些结构中，远端端部62包括多个从远端端部62延伸并且远离通道26的轴向和/或径向延伸的肋或凸起130。 Thus, in some configurations, the distal end portion 62 includes a plurality of portions 62 extending from the distal end of the rib and away from the axial and / or radial passages 26 extending projections or 130. 例如，在一些实施方式中，肋或凸起大致设置成以孔口28为中心的星号的形状。 For example, in some embodiments, ribs or protrusions may substantially arranged in the shape of the aperture 28 as the center of the star. 在使用过程中，凸起130可以构造成在针16的末端46与患者的皮肤或组织接触之前接合患者的皮肤或组织。 During use, the projection 130 may be configured to 46 before the end of the needle 16 in contact with the skin of the patient or the patient's skin or tissue engaging organization. 这样，凸起130凸起130向皮肤或组织施加压力，以在针16的插入之前或大约与此同时刺激患者的压力感受器神经。 Thus, the projection 130 projection 130 apply pressure to the skin or tissue prior to insertion of the needle 16, or about the same time stimulate the patient baroreceptor nerves. 在一些实施方式中，远端端部62包括一个或一系列的例如隆起、锥体、环状物等的凹入或突起，以在针16的插入之前接合患者的皮肤或组织并且刺激患者的压力感受器。 In some embodiments, the distal end portion 62 includes a ridge or a series of, for example, a cone, a ring or the like concave protrusions, inserting the needle 16 prior to engagement of tissue and skin of the patient or the patient's stimulation baroreceptor. 在一些结构中，套筒12的远端端部62基本上是平的、成斜角的等。 In some constructions, the distal end portion 62 of the sleeve 12 is substantially flat, beveled like. 除了别的因素以外，远端端部62的具体构型通常将根据罩10将用于的领域而改变。 In addition to other factors, the specific configuration of the distal end portion 62 of the cover 10 will generally be used in accordance with the field is changed.
罩10的一些结构包括定位在远端端部62处的治疗物质。  cover some of the structure 10 includes positioning a therapeutic substance in the distal end portion 62 of. 例如，在一些实施方式中，远端端部62包括局部麻醉剂。 For example, in some embodiments, the distal end portion 62 comprises a local anesthetic. 在一些实施方式中，远端端部62包括例如碘或外用酒精的杀菌剂和/或抗生素或抗病毒药物。 In some embodiments, the distal end portion 62 includes, for example iodine or rubbing alcohol fungicide and / or antibiotic or antiviral drugs. 在一些实施方式中，治疗物质直至罩10将被使用时才被施用或由帽进行保护直至罩10将被使用。 In some embodiments, the therapeutic substance until the cap 10 is only to be administered by a cap or cover 10 will be protected until used be used.
在某些实施方式中，除了弹簧70的偏置力之外，套筒12基本上不受阻挡地缩回。  In certain embodiments, the biasing force of the spring 70 in addition to the outside, the sleeve 12 is substantially unobstructed retracted. 罩10不需要要求第一只手提供压力和/或操作注射器上的柱塞而第二只手操作另一特征(例如，紧扣)。 10 do not need to cover the requirements of the first hand to provide pressure and / or operation of the plunger on the syringe and the second hand of another operating characteristics (for example, closely). 在一些实施方式中，套筒12的移动自动地接合一个或更多个锁定构件50、110。 In some embodiments, movement of the sleeve 12 automatically engages a locking member 50, 110 or more. 在一些实施方式中，套筒12从大约完全缩回的位置向大约完全伸出的位置的移动自动地防止或阻止重复使用罩10。 In some embodiments, the sleeve 12 to prevent or stop automatically repeated using the shroud 10 to the fully extended position to move about from about fully retracted position. 罩10可构造成便于单手缩回套筒12(暴露针16)、单手操作注射器、单手使套筒12缩回(覆盖针16)和/或单手使特征接合以防止重复使用罩10。 Cover 10 may be configured to facilitate one-handed retraction of the sleeve 12 (the exposed needle 16), one-handed operation of the syringe with one hand so that the sleeve 12 is retracted (covering the needle 16) and / or with one hand so that the engagement features to prevent reuse cover 10. 除了缩回和/或伸出套筒12之外，罩10还可以自动地锁定并且不需要要求外部输入(例如来自使用者的手指的手动操作)来接合轴向锁定构件50和/或旋转锁定构件110。 In addition to the retracted and / or extended the sleeve 12, the cover 10 may be locked automatically and does not require an external input requirements (e.g., from a finger of the user manual operation) 50 is locked axially to engage and / or rotational locking member member 110.
 在一些实施方式中，罩10通过形成具有针支承部30、远端开口42和引导构件44的壳体14而制造。  In some embodiments, the cover 10 is formed through the distal opening 42 of the housing 44 and the guide member 14 and the support portion 30 having a needle manufacture. 在壳体14包括多个部件的实施方式中，制造过程可包括组装壳体14的步骤。 14 includes a plurality of components in the embodiment of the housing, the manufacturing process may include the step 14 of the housing assembly. 套筒形成为具有轨道80-84。 A sleeve having a track formed 80-84. 引导构件44与第一轨道80的插入部86对准。 The guide rail member 44 and the first insertion section 8680 is aligned. 套筒12通过远端开口42滑动地移动。 Through the distal opening 42 of the sleeve 12 is slidably moved. 在一些变型中，引导构件44移上插入部86中的倾斜部并且大约在平形面88处卡扣到第一轨道80中，从而防止引导构件44返回到插入部86。 In some variations, the guide member 44 moves in the insertion portion 86 and the inclined portion formed around the flat surface 88 to snap the first rail 80, thereby preventing the guide member 44 returns to the insertion portion 86. 针16与壳体14的针支承部30联接。 Needle 16 and needle support housing portion 30 of the coupling 14. 弹簧16插入到壳体14的中央腔室36中并且定位成偏压套筒12。 Spring 16 is inserted into the central chamber 36 of the housing 14 and positioned to bias the sleeve 12.
如图1C和图1D所示，罩10可包括可移除地联接至壳体14的帽32。  FIG. 1C and FIG. 1D, the cover 10 may include a removable cap 32 coupled to the housing 14. 帽32的远端端部能够通过铰链33在打开位置(图1C)与关闭位置(图1D)之间移动。 The distal end cap 32 by a hinge 33 can be in the open position (FIG. 1C) and movable between a closed position (FIG. 1D). 在关闭位置中，帽32例如在罩10的运送与储存期间减少或防止套筒12和壳体14的远端端部38的污染。 In the closed position, the cap 32 e.g. decrease or prevent the distal end portion 14 of the sleeve 12 and the housing 38 during shipping and storage of the cover 10. 帽32通常保持处于关闭位置直至注射和/或抽吸过程之前，此时，帽32移动到打开位置和/或从壳体14移除。 Before the cap 32 is usually held in a closed position until the injection and / or pumping processes, this time, the cap 32 is moved to the open position and / or removed from the housing 14. 在一些实施方式中，在注射和/或抽吸过程之前打开或移除帽32由于套筒12覆盖针16而并不使针16暴露，如图1和图1A所示。 In some embodiments, prior to injection and / or aspiration procedure to open or remove the cap 32 since the sleeve 12 covering the needle 16 and the needle 16 is not exposed, as shown in Figures 1 and 1A. 此外，如果将帽32移除，则可以立即将帽32丢弃，因为一旦注射和/或抽吸过程完成，套筒12还覆盖针16。 Further, if the cap 32 is removed, the cap 32 may be discarded immediately, because once the injection and / or aspiration process is completed, the sleeve 12 also covers the needle 16. 帽32可以包括构造成例如有助于打开和关闭帽32的开口部37。 32 may include a cap configured to open and close the opening for example to assist portion 32 of the cap 37.
在一些实施方式中，帽可包括可动的或可移除的部分以辅助从药瓶适当地抽取剂量。  In some embodiments, the portion of the cap may include a movable or removable to aid in extraction from the dose vial appropriately. 例如，帽32可定尺寸成并且构造成防止套筒12缩回到壳体14中足够的距离而使引导构件44会进入第二轨道82或转移轨道84。 For example, the cap 32 may be sized and configured to prevent retraction of the sleeve 12 into the housing 14 leaving a sufficient distance into the second guide rail member 44 will transfer orbit 82 or 84. 在一些实施方式中，帽32构造成防止套筒12缩回到壳体14中足够远而接合轴向锁定构件50和/或旋转锁定构件110，这样会防止装置的进一步使用。 In some embodiments, the cap 32 is configured to prevent retraction of the sleeve 12 to the housing 14 far enough to engage the locking member 50 axially and / or rotation of the locking member 110, which will prevent further use of the device. 在一些实施方式中，帽32限制套筒12缩回使得引导构件44保持滑动地接纳在第一轨道80中。 In some embodiments, the cap 32 is retracted so that the guide sleeve 12 limiting member 44 remains slidably received in the first track 80.
为减少焦虑，特别是减少儿童的焦虑，帽32、壳体14和/或套筒12可设置有各种美学设计，例如通常认为愉悦和安慰儿童的彩虹、气球、卡通人物或其他插图。  In order to reduce anxiety, especially to reduce the anxiety of children, cap 32, housing 14 and / or sleeve 12 may be provided with a variety of aesthetic design, for example, it is generally considered the pleasure and comfort of children rainbow, balloons, cartoon characters or other illustration. 这样，可允许儿童患者在注射和/或抽吸过程之前从各种不同的罩10中进行选择。 Thus, the child may be allowed to select from a patient in a variety of cover 10 prior to injection and / or aspiration process. 除了被着色或带有标记之外或作为着色或带有标记的替代方式，帽32还可以制造成类似于各种不同的卡通人物或其它对象，使得在注射和/或抽吸过程之前从壳体14移开时，帽32可以在注射和/或抽吸过程中作为分散注意力的事物呈现给儿童患者。 In addition to being marked with colored or addition or as an alternative to colored or marked with the cap 32 also can be made to resemble a variety of cartoon characters or other objects, so that prior to injection and / or aspiration process from shell when the body 14 is removed, the cap 32 can serve as distractions presented to pediatric patients in the injection and / or aspiration process. 当制造成类似于卡通人物或其它对象时，帽32的尺寸和大致圆筒形状使帽32特别适于被儿童用作手指玩偶。 When manufactured to resemble cartoon characters or other objects, the size of the cap 32 and the cap 32 substantially cylindrical shape is particularly suitable for use as child finger doll. 这些特征中的每个均对减少被许多儿童在注射和/或抽吸过程之前、期间以及之后感受到的焦虑或恐惧提供了机会。 Each of these features are to reduce the number of children being prior to injection and / or aspiration process, during and after feel anxiety or fear provided the opportunity.
图1至图8A示出了在操作周期的过程中处于各种位置的罩10，所述各种位置为从图1示出的初始或准备使用的伸出的构型到图5示出的中间或完全缩回位置并且到图8A示出的最终或防止重复使用的伸出的构型。  FIG. 1 to FIG. 8A shows in various positions during the operation cycle of the cap 10, the various positions is shown in Figure 1 from an initial configuration ready for use or extended to 5 shown intermediate or to a fully retracted position and Figure 8A shows the final configuration extending or prevent reuse. 应当理解的是，下面给出了示例性实施方式并且并非意在进行限制。 It should be understood that the below given exemplary embodiments and are not intended to be limiting. 还应当理解的是，尽管该实施方式描述了用于穿刺患者的皮肤的针16，但是罩10并不限于这种应用。 It should also be understood that, although the embodiments described by way of the needle 16 for piercing the skin of a patient, but the cover 10 is not limited to this application.
图1至图1C示出了处于初始的准备使用的构型中的罩10。  FIG. 1 to FIG. 1C shows in an initial configuration ready for use in the cover 10. 如上所述，罩10联接到注射器或其它医疗装置，因而将注射器放置成与针16流体连通。 As described above, the cover 10 is coupled to a syringe or other medical device, and thus the syringe is placed in fluid communication with the needle 16. 在移除帽32(如果使用的话)并且采取表面预处理步骤(如果适当的话，例如将消毒剂施用到表面)之后，罩10的远端端部62可以在期望的穿刺位置处靠着着患者的皮肤放置。 After removing the cap 32 (if used) and take surface pretreatment step (if appropriate, for example, the disinfectant is applied to the surface), the distal end portion of the cover 6210 may puncture the desired position against the patient place skin.
现在参照图2，罩10以第一部分缩回的构型示出。  Referring now to Figure 2, a first portion of the cover 10 to the retracted configuration is shown. 套筒12的缩回通常通过使用者沿着远端方向在罩10和/或注射器上施加压力而开始，从而促使套筒12朝向近端方向克服弹簧70的偏置力。 Retracting sleeve 12 is typically started by a user applying pressure in the distal direction along the cover 10 and / or syringes, thus contributing to the sleeve 12 toward the proximal direction against the bias of spring 70. 套筒12的缩回进而使针16的远端末端96暴露并且开始由针16穿刺到患者的皮肤中。 Retracting sleeve 12 thereby enabling the distal end 96 of the needle 16 is exposed and begins to puncture by the needle 16 into the patient's skin. 定位在第一轨道80中的壳体14的引导构件44对套筒12进行引导以轴向地移动到大约第一轨道80和转移轨道84的交点。 Positioned in the first track 80 in the housing 14 of the guide member 44 pairs of guide sleeve 12 to move axially to the first rail intersection about 80 and 84 transfer orbit. 当到达第一轨道80和转移轨道84的交点时，引导构件44坐靠将引导构件引到到转移轨道84中的平形面88。 When you reach the intersection of the first rail 80 and the transfer orbit 84, the guide member 44 is seated against the guide member to lead to a transfer orbit 84 flat-shaped surface 88. 在操作的该阶段中，过程可以颠倒。 In this phase of operation, the process can be reversed. 如果将远端压力去除，则罩10能够复位到图1所示的初始的准备使用的构型。 If the distal pressure is removed, the cap 10 can be reset to the initial configuration ready for use as shown in FIG. 如图2A和图2B所示，随着套筒12的凸缘64向近端移动，轴向锁定构件50通过凸缘64中的切口116。 2A and 2B, the sleeve 12 with the flange 64 moves proximally, the locking member 50 axially through the flange 64 of the notch 116.
在图3所示的构型中，套筒12已进一步向近端移动并且针16已经进一步被暴露。  In the configuration shown in Figure 3, the sleeve 12 has been moved further proximally and the needle 16 has been further exposed. 此时，套筒12已足够地向近端移动使得通道26的近端部分90已开始接纳针支承部30，轴向锁定构件50已通过凸缘64中的切口116(图3A)，并且引导构件44定位在转移轨道84中。 At this time, the sleeve 12 has moved sufficiently proximally so that the proximal end portion 90 of the passageway 26 has started receiving the needle bearing portion 30, the axial locking member 50 has a flange 64 through the notch 116 (FIG. 3A), and the guide member 44 is positioned in the transfer orbit 84. 随着套筒12向近端移动，引导构件44经过分隔第一轨道80和第二轨道82的转移轨道84从而促使套筒12绕轴线18旋转大约例如至少约5°和/或小于或等于约90°的度数。 As the sleeve 12 is moved to the proximal end of the guide member 44 through the transfer orbit 84 separating the first and second rail track 80 82 18 thus contributing to the sleeve 12 about the axis of rotation about, for example at least about 5 ° and / or less than or equal to about 90 ° degrees. 套筒12的旋转进而使包括阻挡构件102的凸缘64旋转。 Rotating sleeve 12 further includes a barrier so that the flange 64 of the rotary member 102. 如图3B所示，阻挡构件102的倾斜面106朝着旋转锁定构件110的倾斜面112旋转。 3B, the inclined surface of the barrier member 102 of the lock 106 toward the inclined surface 112 rotates the rotary member 110. 套筒12的凸缘64的阻挡构件102的继续旋转使倾斜面106、112滑动地接合，从而径向向内偏转阻挡构件102并且产生轻微的但明显的阻力。 The flange 12 of the sleeve 64 so that continued rotation of the blocking member 106, 112 slidably engage the inclined surface 102, thereby radially inwardly deflecting the barrier member 102 and a slight but significant resistance. 在一些实施方式中，如图所示，阻挡构件102的长度通常大约与转移轨道84的长度相同或短于转移轨道84的长度。 In some embodiments, as shown, the length of the barrier member 102 is generally about the same length of the transfer rail 84 is the same as or shorter than the length 84 of the transfer orbit.
参照图4和图4A所示，套筒12继续缩回到壳体14中，这使针16进一步暴露。  Referring to FIG. 4 and 4A, the sleeve 12 continues to retract into the housing 14, the needle 16 which further exposed. 引导构件44已从转移轨道84切换到第二轨道82，因而进一步相对于壳体14旋转套筒12。 The guide member 44 from the transfer orbit 84 is switched to the second rail 82, so 14 is rotated further with respect to the housing sleeve 12. 针支承部30已经被通道26的近端部分90进一步接纳。 30 has been needle support portion 26 of the proximal portion 90 further receiving channel. 如图4B所示，一旦阻挡构件102的倾斜面106旋转越过旋转锁定构件110的倾斜面112的最高点，阻挡构件102即径向向外偏转，因而大约回到其如图2B所示的径向位置。 4B, once the inclined surface 106 to block rotation of the rotation lock member 102 over the highest point of the inclined surface 112 of member 110, i.e., radially outward deflection of the barrier member 102, and thus return to about its diameter shown in Figure 2B to the position. 在该构型中，大致呈平形的面108、114产生物理止挡作用，从而阻止套筒12的反旋转。 In this configuration, the substantially flat-shaped surface 108, 114 produce physical stop action, thereby preventing reverse rotation of the sleeve 12. 这进而防止引导构件44返回到转移轨道84中，如将在下面讨论的。 This in turn prevents the guide member 44 to return to the transfer orbit 84, as will be discussed below. 在一些实施方式中，阻挡构件102的向外偏转产生能触知的振动和/或例如“劈啪”的能听见的声音，这可以提供旋转锁定构件110已经被锁定并且反旋转得到防止的验证。 In some embodiments, the barrier members 102 are deflected outwardly generating a tactile vibration and / or, for example, "crack" can hear the sound, which would provide rotational locking member 110 has been locked and the verification of the reverse rotation is prevented.
图5示出了罩10的完全缩回的构型。  FIG. 5 shows a fully retracted configuration of cover 10. 针16处于其呈现最长暴露的针长度的最大暴露状态。 Pin 16 is in its longest exposure presents the maximum exposure to the state of the needle length. 套筒12的远端端部62大致与壳体12的远端端部38齐平。 The distal end portion 62 of the sleeve 12 is substantially the distal end 12 of the housing 38 flush. 通道26的近端部分90大约完全接纳针支承部30。 Channel 90 about the proximal portion 26 fully accept the needle bearing portion 30. 弹簧70基本上被压缩到其完全压缩的构型。 Spring 70 is substantially compressed to its fully compressed configuration. 在若干实施方式中，这是注射器的物质通过毂部20和针16被注射到患者体内的构型。 In several embodiments, the material which is to be injected by the syringe hub 20 and the needle 16 into the patient's configuration.
参照图6和图6A，示出了退出针16的初始阶段。  Referring to FIGS. 6 and 6A, shows an initial stage exit of the needle 16. 退出通常开始于当使用者从患者抽离注射器时，或当使用者在罩10和/或注射器上施加较小的朝向远端的压力时，因而允许弹簧70的偏置力使套筒12向远端伸出。 When you exit usually begins when the user pulled the syringe from the patient, or when the user exerts less pressure toward the distal end of the cover 10 and / or syringe, thus allowing the biasing force of the spring 70 to the sleeve 12 extending distally. 随着套筒12向远端伸出，套筒12将针16接纳到通道26中，从而覆盖针16的至少一部分(例如远端端部)。 As the sleeve 12 extending distally, sleeve 12 receiving the needle 16 into the passage 26 so as to cover at least a portion of the needle 16 (e.g., distal end). 套筒12朝向远端的移动同时使引导构件44沿着第二轨道82滑动。 Moving the sleeve 12 toward the distal end of the guide member 4482 while sliding along the second track. 大致呈平形的面108、114的接合抑制或防止了套筒12的反旋转，这进而防止了引导构件44在第二轨道82与转移轨道84之间的交点处切换到转移轨道84中。 A substantially flat engaging surfaces 108, 114 form a reverse rotation inhibiting or preventing the sleeve 12, which in turn prevents the guide member 44 of the switch 82 at the intersection of the second rail 84 and the transfer orbit between the transfer orbit 84.
图7和图7A示出了罩10的构型，其中，套筒12已经进一步伸出并且针16已经进一步被覆盖。  FIG. 7 and 7A shows a configuration of the cover 10, wherein the sleeve 12 has been further extended and the needle 16 has further been covered. 在该阶段的操作中，随着套筒12向远端移动，凸缘64的向外延伸部100滑动地接合轴向锁定构件50。 At this stage of the operation, as the sleeve 12 is moved distally, outwardly extending portion 100 of the flange 64 slidably engage axial locking member 50. 凸缘64的向外延伸部100促使轴向锁定构件50径向向外并且产生轻微的但明显的阻力。 Outwardly extending portion 100 of the flange 64 is locked axially urge member 50 radially outwardly and a slight but significant resistance.
现在转移到图8和图8A，其描绘了罩10的防止重复使用的伸出的构型。  now transferred to FIGS. 8 and 8A, which depicts the configuration of preventing covers 10 extending reuse. 套筒12已经完全伸出并且完全覆盖针16。 The sleeve 12 has been fully extended and fully covering the needle 16. 弹簧70已使套筒12向远端移动直到凸缘64坐靠到肩部40。 Spring 70 has the sleeve 12 is moved distally until the flange 64 seats against the shoulder 40. 当凸缘64的向外延伸部100移动到轴向锁定构件50的第二端54的远端时，轴向锁定构件50相对于凸缘64的向外延伸部100径向向内卡扣。 When the flange 64 outwardly extending portion 100 moves to the second axial locking member 50 of the distal end 54, the axial locking member 50 with respect to the outwardly extending flange portion 64 of the 100 radially inward snap. 因而轴向锁定构件50产生物理止挡作用以阻止套筒12又向近端缩回。 Thus axial locking member 50 generates physical stop action to prevent the sleeve 12 ED retracted proximally. 在一些实施方式中，至少一个轴向锁定构件50的向内偏转产生能触知的振动和/或例如“劈啪”的能听见的声音，这能够提供轴向锁定构件50已经接合的验证。 In some embodiments, the at least one axial locking member 50 to deflect inwardly generating a tactile vibration and / or, for example, "crack" can hear the sound, which can provide axial locking member 50 has engaged verified.
