Abstract

The utility model discloses a prevent felting needle cover, can form the needle nest plate of the needle body of cladding syringe needle after two closures, the one end of this needle nest plate is this somatic part, and the other end is sharp portion, and formation an organic whole is connected on this somatic part one side limit of two needle nest plates, and forms the window that is used for inserting the eye of a needle of syringe needle on its connecting wire, the opposite side edge of this somatic part of two needle nest plates corresponds respectively to be equipped with locks convex part and locking concave part, should lock the convex part and plant with two when this locking concave part the locking of needle nest plate. This prevent felting needle cover simple structure, convenient to use during the use gets up the syringe needle cladding, does not influence the normal use of syringe needle, withdraws the syringe needle to in the needle cover after the messenger uses up to locking is protected, thereby avoids stabbing in subsequent processing the nurse, anti -skidding nurse's safety, and the to prevent accidental disease infects.

Description

Anti-stab needle guard

Technical field

This utility model relates to medical apparatus, relates to a kind of anti-stab needle guard specifically.

Background technology

Nurse because of working principle, often with suture needle, cutter, to cut and the blood, body fluid, secretions etc. of patient contact, this makes nurse often be exposed in occupational risk factor, especially sharp injury.And ward nurse is because of the character of its work, the most easily there is sharp injury, particularly pricking wound.Pricking wound is a kind of unexpected injury being enough to make wounded body hemorrhage of skin deep part, therefore can be inoculated in victim's body by the blood of pathogen contamination or body fluid.Pricking wound happens occasionally in the middle of clinical nurse, and patient has various disease, particularly the courage and uprightness such as hepatitis B, hepatitis C, syphilis, acquired immune deficiency syndrome (AIDS) of present China spread disease and are also increasing year by year, in this case, nursing staff, as the needle sting of infected mistake, causes great threat to the health of nursing staff beyond doubt.

Summary of the invention

In order to overcome above-mentioned defect, this utility model provides a kind of anti-stab needle guard, effectively avoids pricking wound, and protection Nurse safety, prevents inadvertent contamination disease.

This utility model in order to the technical scheme solving its technical problem and adopt is: a kind of anti-stab needle guard, comprise the needle guard sheet that can form the needle body of coated syringe needle after two panels closes, one end of this needle guard sheet is body, the other end is tip, body one side of two needle guard sheets is connected to form one, and on its connecting line, form the window of the eye of a needle for inserting syringe needle; On another side of the body of two needle guard sheets, correspondence is provided with locking protuberance and locking recess respectively, is locked by needle guard sheet described in two panels when this locking protuberance is inserted in this locking recess.

As further improvement of the utility model, in needle guard sheet described in two panels, correspondence is provided with semicircular pin folder portion respectively, and pin folder portion when two needle guard sheets close on it is mutually closed and be fixedly clamped by the needle body of described syringe needle.

As further improvement of the utility model, the described pin folder portion on every sheet needle guard sheet is two, is arranged at the body of this needle guard sheet respectively on its one end, tip and on described tip.

As further improvement of the utility model, described locking protuberance comprises a fixed leg, and this fixed leg is provided with some barbs, and described locking recess comprises fixing hole, this fixing hole medial surface is provided with the grab of ring-type, and this grab and described barb can be fixed mutually.

As further improvement of the utility model, described body is semi-cylindrical, and described tip is half cone-shaped.

As further improvement of the utility model, described needle guard sheet is that elastic material is made.

The beneficial effects of the utility model are: this anti-stab needle guard is coated by syringe needle, do not affect the normal use of syringe needle, are retracted in needle guard after using by syringe needle; and locking is protected; thus avoid stabbing nurse in subsequent treatment, anti-skidding Nurse safety, prevent unexpected disease from infecting.

Detailed description of the invention

Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But protection domain of the present utility model is not limited to following embodiment, the simple equivalence namely in every case done with this utility model claim and description changes and modifies, and all still belongs within this utility model patent covering scope.

Consult Fig. 1-5, a kind of anti-stab needle guard, comprise the needle guard sheet 1 that can form the needle body 101 of coated syringe needle 100 after two panels closes, one end of this needle guard sheet is body 11, the other end is tip 12, body one side of two needle guard sheets is connected to form one, and on its connecting line, form the window 13 of the eye of a needle 102 for inserting syringe needle 100; On another side of the body of two needle guard sheets, correspondence is provided with locking protuberance 14 and locking recess 15 respectively, is locked by needle guard sheet described in two panels when this locking protuberance is inserted in this locking recess.

In needle guard sheet described in two panels respectively correspondence to be provided with when 16, two, semicircular pin folder portion needle guard sheet closes pin folder portion on it mutually closed and be fixedly clamped by the needle body of described syringe needle.Described pin folder portion on every sheet needle guard sheet is two, is arranged at the body of this needle guard sheet respectively on its one end, tip and on described tip.

Described locking protuberance comprises a fixed leg 141, and this fixed leg is provided with some barbs 142, and described locking recess comprises fixing hole 151, and this fixing hole medial surface is provided with the grab 152 of ring-type, and this grab and described barb can be fixed mutually.

Described body is semi-cylindrical, and described tip is half cone-shaped.Described needle guard sheet is that elastic material is made.

During use, the needle body 101 of syringe needle 100 is put into two panels needle guard sheet 1, the eye of a needle 102 passes from the window the connecting line of two needle guard sheet bodies, then locking protuberance is inserted in locking recess and lock, lock-out state is see Fig. 3, the fixed leg of now locking on protuberance inserts in the fixing hole of locking recess, and the barb on fixed leg and the grab on fixing hole are fixed, and realizes the fixing of needle guard sheet.Because needle guard sheet is elastomeric material, with the clamping action in hour hands folder portion, make between needle guard and needle body in elastic compression state.

When starting to put into; in order to not affect the normal use of syringe needle, the needle body of syringe needle and needle point pass outside needle guard, and now syringe needle can normally use; see Fig. 4; after using syringe needle, pull with hand the eye of a needle and move backward, make the needle body of syringe needle be fully retracted in needle body; see Fig. 5; needle point can be protected like this to expose and to stab nurse, avoid potential potential safety hazard, thus protection Nurse safety.

This anti-stab needle guard structure is simple, and easy to use, cost of manufacture is low, does not namely affect the normal use of syringe needle, again can after syringe needle uses coated syringe needle, to avoid potential potential safety hazard.
