Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of syringe, especially relate to a kind of anti-acupuncture syringe.
Background technology
Syringe is to be used for liquid or gas are injected into bodily tissue or therefrom extraction as a kind of common medical apparatus and instruments.Yet in the routine operation process of syringe, for example the syringe syringe needle of choosing, with the syringe needle bending, unmake and will pick up the link that syringe drops into sharp instrument box the time regular meeting situation that medical personnel are stabbed by syringe needle takes place.Pricking wound is a kind of unexpected injury of making wounded body hemorrhage of being enough to of skin deep part, behind the pricking wound, often entered by the blood of pathogen contamination in the body of wounded body, cause nosocomial infection, make medical personnel's personal safety have great hidden danger through the blood propagation.In addition conventional injector also exists: complex structure, cost height, problems such as operation inconvenience.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have proposed solution miscellaneous.For example; Chinese patent literature discloses a kind of syringe [application number: 01113478.X] with safe protective slide sleeve; this syringe has increased tubular protection sliding sleeve, fixed mount, preceding locking rotating vane sheet, back locking rotating vane sheet, spring; to protect sliding sleeve to be divided into the front and back section; leading portion is a closing in shape; fixed mount is installed on the needle stand; locking rotating vane sheet and back locking rotating vane sheet before on fixed mount, being with; spring one end and fixed mount offset; the other end offsets with the leading portion of protection sliding sleeve, and entry needle passes spring.
Such scheme has improved the problem of existing poor stability to a certain extent; prevent that by increasing tubular protection sliding sleeve mistake is stabbed phenomenon in the use; but this has just increased the production cost of syringe greatly; also brought inconvenience to use; this scheme still exists in addition: complex structure; it is reasonable inadequately to design, operation inconvenience, problems such as protection effect difference.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of reasonable in design, simple in structure, prevent the anti-acupuncture syringe that the syringe needle mistake is stabbed.
For achieving the above object, the present invention has adopted following technical proposal: this anti-acupuncture syringe, comprise syringe, described syringe end is provided with syringe needle, in syringe, be provided with piston and the piston rod that is connected on the piston, it is characterized in that, being arranged with on the described syringe needle can be along the axially movable anti-acupuncture medicated cap body of syringe needle, be connected with connecting rod on the described anti-acupuncture medicated cap body, described connecting rod is slidingly connected with being arranged on the syringe and along the axially extended slide rail of syringe, can realize that pitman shaft is to localized detent mechanism being provided with between connecting rod and the slide rail when anti-acupuncture medicated cap body is placed in needle tip.By the anti-position of acupuncture medicated cap body on syringe needle of slide link control, when being placed in needle tip, anti-acupuncture medicated cap body is fixed on needle tip by the anti-acupuncture medicated cap body of detent mechanism, and make needle tip by anti-acupuncture medicated cap body parcel, stabbed by the syringe needle mistake when avoiding using.
In above-mentioned anti-acupuncture syringe, described detent mechanism comprises the shrouding that is arranged on slide rail upper end and is arranged on locating piece on the connecting rod, described shrouding be provided with locating hole and when anti-acupuncture medicated cap body is placed in needle tip described locating piece can be located in the described locating hole.Shrouding makes that connecting rod is difficult for breaking away from slide rail, can avoid anti-acupuncture medicated cap body rollback when locating piece is positioned at locating hole, come off.
In above-mentioned anti-acupuncture syringe, described connecting rod is provided with and can makes described locating piece break away from the control structure of locating hole.Control structure can be separated locating piece from locating hole.
In above-mentioned anti-acupuncture syringe, described control structure comprises to be located on the connecting rod and support slipper that contacts with slide rail and the end of pushing of being located at the connecting rod lower end, described support slipper is positioned at the top of locating piece, describedly push the below that end is positioned at locating piece, thus described push end perk laterally and in the time will pushing end and press down described connecting rod can be that fulcrum produces deformation and makes locating piece break away from locating hole with the support slipper.Promptly when pushing end, connecting rod is that fulcrum produces deformation with the support slipper, makes locating piece break away from locating hole, continues slide link and makes anti-acupuncture medicated cap body break away from needle tip.
In above-mentioned anti-acupuncture syringe, described locating piece is wedge shape, and locating piece is higher than an end of close syringe needle away from an end of syringe needle.Be convenient to locating piece is advanced in the locating hole, and locating piece enters and is difficult for behind the locating hole breaking away from.
In above-mentioned anti-acupuncture syringe, described locating piece is made by hard material or elastomeric material.
In above-mentioned anti-acupuncture syringe, described connecting rod is made by the strip shape body of uniform thickness and is bending, and the bending shape of this connecting rod conforms to the syringe profile for connecting rod when anti-acupuncture medicated cap body is positioned at bottom the syringe needle.Connecting rod applying syringe needle curvature brings any inconvenience can for medical personnel's use.
In above-mentioned anti-acupuncture syringe, described connecting rod, push that end, support slipper and locating piece are connected as a single entity and by the plastics one-shot forming; Be connected as a single entity formula and of described shrouding, slide rail and syringe by the plastics one-shot forming; Described anti-acupuncture medicated cap body is made by rubber.Integral structure makes structure more firm, and cost is low.
In above-mentioned anti-acupuncture syringe, described anti-acupuncture medicated cap body is the hourglass shape, is provided with axially extending bore in anti-acupuncture medicated cap body, and described syringe needle is located in the axially extending bore.The anti-acupuncture medicated cap body of hourglass shape makes better protecting effect.
In above-mentioned anti-acupuncture syringe, the width of described support slipper is greater than the width of connecting rod, and described slide rail is the slot type slide rail, and width and the inboard width of slide rail that described connecting rod is positioned at slide rail and support slipper adapt.Make the support slipper two ends be resisted against in the slide rail, the connecting rod lower end can not break away from slide rail.
Compared with prior art, the advantage of this anti-acupuncture syringe is: simplicity of design is reasonable, and is easy to operate, when anti-acupuncture medicated cap body is positioned at needle tip is to prevent effectively that syringe needle from exposing, and realizes the effect of anti-acupuncture, avoids maloperation to cause pricking wound, safe, cost is low, and protection effect is good.
