Description
Technical field
The application relates to a kind of adjustable fitting, especially relates to a kind of adjustable fitting of the paracentesis depth for adjusting puncture needle.
Background technology
In the many medical examination programs that adopt now, only need quite a small amount of blood sample (about 5-50 μ L), a small amount of like this sample usually can cut by the skin at a selected position or puncture and obtain, on for example pointing, and then gather the blood that 1-2 drips.Along with such as the popularizing of the domestic testing instruments such as blood glucose self-monitoring, can by testee voluntarily demand simple and that take a blood sample safely produce thereupon.
Traditional puncture needle generally has hard body and aseptic piercing assembly, syringe needle for example, and its distal process from this body goes out; This puncture needle is used for piercing through skin, thus can be from formed puncture wound sample of blood, drawn.Blood is usually by the finger tip collection, because its source is the most sufficient; Yet blood also can gather from other position, for example ear-lobe or extremity.
In order to reduce the Anxiety of user when the skin puncture, and the result's that guarantees to puncture repeatability, be equiped with the multiple sting device of spring thereby be developed.Simultaneously, in order to cooperate the skin thickness of different sufferers or different blood sampling sites, many sting devices also provide the design of capable of regulating paracentesis depth.
See also Figure 1A-1B, it is the sketch map of sting device of the capable of regulating paracentesis depth of prior art.Shown in Figure 1A, the sting device 10 of general capable of regulating paracentesis depth has keeper 11, rotatable lid 12 and piercing assembly 13 usually, wherein this keeper 11 is used for the main body 101 of this sting device 10 fixing, this piercing assembly 13 is positioned at this keeper 11 and this main body 101, and this cover the outside of an end of 12 these keepers 11 of coating, and having opening 122 to prop up position to be punctured, this piercing assembly 13 has bracket 131 and needle tip 132.When this piercing assembly 13 is advanced by the spring (not shown) and when moving to puncture direction P, this bracket 131 is stopped to only have this needle tip 132 to stretch out outside this keeper 11 and this lid 12 by this opening 122 by the stop surface 112 of this keeper 11; And the length that this moment, this needle tip 132 was stretched out this lid 12 is D1, and this also is that sting device 10 can puncture into the interior degree of depth of skin.
As shown in Figure 1B, this keeper 11 and this lid 12 of this sting device 10 have respectively corresponding helicitic texture 111,121, therefore this lid 12 can move to this puncture direction P by the action of rotation, so that the distance between this opening 122 of this stop surface 112 of this keeper 11 and this lid 12 increases; Because the relative position between this piercing assembly 13 and this keeper 11 still remains unchanged, this lid 12 will be so that this needle tip 132 be stretched out the contraction in length of this lid 12 is D2 to the mobile of this puncture direction P, thereby this sting device 10 can puncture into the interior degree of depth of skin and also will shoal.
Yet, such design so that this sting device 10 when adjusting the degree of depth to be punctured, can produce slit I (as shown in Figure 1B) between this keeper 11 and this lid 12, and this slit I accumulates dirt easily, then cause easily again the damage of part or lose if will cover continually 12 disassembly, cleaning.In addition, in the time this lid 12 will being recalled to position shown in Figure 1A by position as shown in Figure 1B, user also may be held in I place, this slit and crushes when recalling to because holding.
In sum, industry is needed a kind of accessory of paracentesis depth of capable of regulating sting device badly, allow user when adjusting the degree of depth to be punctured, the Gai Buhui of sting device moves forward and backward, not only reduce dirt and lodge in chance in the slit of sting device, also provide the another kind of sting device when design to select.
