Description
Technical field
This utility model relates to a kind of anti-pricking wound, uses and deal with simply and easily medical instruments, is specially a kind of from kissing the formula syringe.
Background technology
Along with the development of society, the improving constantly of living standards of the people, medical and health industry constantly perfect, the clinical care industry is also grown in strength at development.Yet in clinical nursing activity, various injections, transfusion are the nursing technique operations of the most common workload maximum.Yet, just in the routine work of this maximum, the occupational exposure that is caused by pricking wound and potential danger that the blood relationship that causes infects is on the rise, wherein the most common, to threaten also maximum be hepatitis B, hepatitis C, acquired immune deficiency syndrome (AIDS).Studies confirm that in a large number: the nurse is needle injuries and infection and through the pathophorous high-risk professional colony of blood.Although the disposable syringe technology that has had now some can preventive injection stab, but these technical tools also exist many leaks and shortcoming, as complex structure, inconvenient operation, with high costs, can not play effect that good preventive injection stabs etc., brought some inconvenience for nursing staff's operation.
For nursing staff's safety and health, the syringe of therefore designing a kind of safe ready and can well preventive injection stabbing has been a good problem to study.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides a kind of simple in structure, safe ready and can play safety that good preventive injection stabs from kissing the formula syringe.
The purpose of this utility model is achieved in that
From kiss formula syringe, comprise syringe 6, be arranged on the axis of the piston 7 in the syringe 6, be fixed on the piston handle 8 on the axis of the piston 7, the front end of syringe 6 is provided with nipple 5, be fixed on the pintle 3 on the nipple 5, and be arranged on syringe needle 2 on the pintle 3, and being covered with pin medicated cap 1 on the described pintle 3, the outer surface of described pintle 3 is provided with vertical pintle groove 4, pintle 3 connecting needle medicated caps 1, pin medicated cap 1 and pintle 3 junctions inwall on be provided with the vertical pin medicated cap fin 9 corresponding with vertical pintle groove 4;
Described pintle groove 4 is fastened and connected with pin medicated cap fin 9;
Described pintle groove 4 bottom faces are coarse, and other faces are smooth;
The end opening diameter that described pin medicated cap 1 is connected with syringe 6 is greater than the other end of pin medicated cap 1.
Positive beneficial effect:This utility model is simple in structure, and is easy to operate, is fastened and connected by pintle groove and pin medicated cap fin, can realize that the pin medicated cap well is fixedly connected with pintle; The setting of coarse and other groove smooth-sided compression candles degree of pintle groove groove bottom, the heavy caliber setting of the end that the pin medicated cap is connected with syringe, can allow syringe needle and pin medicated cap easy to connect, and good fixing effect, be not easy to come off, and can prevent in the cover process of returning of pin medicated cap to greatly reduce the injury that the nursing staff is subject to because of picking and placeing of pin medicated cap owing to the too little pricking wound problem that causes of pin medicated cap bore, be convenient to penetration and promotion.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of syringe needle locking cap;
Among the figure be: pin medicated cap 1, syringe needle 2, pintle 3, pintle groove 4, nipple 5, syringe 6, the axis of the piston 7, piston handle 8, pin medicated cap fin 9.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described further:
As shown in Figure 1 and Figure 2, from kiss formula syringe, comprise syringe 6, be arranged on the axis of the piston 7 in the syringe 6, be fixed on the piston handle 8 on the axis of the piston 7, the front end of syringe 6 is provided with nipple 5, be fixed on the pintle 3 on the nipple 5, and be arranged on syringe needle 2 on the pintle 3, be covered with pin medicated cap 1 on the described pintle 3, the outer surface of described pintle 3 is provided with vertical pintle groove 4, pintle 3 connecting needle medicated caps 1, pin medicated cap 1 and pintle 3 junctions inwall on be provided with the vertical pin medicated cap fin 9 corresponding with vertical pintle groove 4;
Described pintle groove 4 is fastened and connected with pin medicated cap fin 9;
Described pintle groove 4 bottom faces are coarse, and other faces are smooth;
As shown in Figure 2, the end opening diameter that is connected with syringe 6 of described pin medicated cap 1 is greater than the other end of pin medicated cap 1.
6 ~ 8 evenly vertical pin medicated cap fins 9 of projection are arranged in pin medicated cap 1 inside, just with the outer surface of pintle 3 on vertical pintle groove 4 match, each bar pin medicated cap fin 9 of pin medicated cap has three contact surfaces with the vertical pintle groove 4 of pintle, wherein two sides are smooth, right opposite is slightly coarse, have frictional force, pin medicated cap 1 and pintle 3 are exactly by linking together over against the frictional force between the matching surface, make pin medicated cap 1 difficult drop-off.The lower edge of pin medicated cap head and syringe joins, and the end opening diameter that is connected with syringe 6 of pin medicated cap 1 is greater than the other end of pin medicated cap 1, and operator pull out pin medicated cap time ratio and are easier to extract, and has reduced and has pulled out firmly that pin causes the syringe needle bounce-back and the danger that causes pricking wound; Because pin medicated cap 1 head diameter is larger, operator can inject syringe needle in the pin medicated cap 1 when returning the trocar medicated cap easily, are unlikely to make syringe needle wrong plug position and cause pricking wound.When pulling out syringe needle, syringe 6 and pin medicated cap 1 toward opposite direction rotation, relied on that resistance between pin medicated cap 1 and pintle 3 vertical lines is easy just to be pulled out syringe needle, and pintle 3 is enclosed within and protects the operator on the syringe needle, avoided pricking wound.Pin medicated cap 1 and pintle 3 are to link together by the frictional force between the vertical line, and little than before transforming of frictional force, the head diameter of pin medicated cap 1 is than cervical region and body is much bigger and join with the lower edge of syringe 6, so no longer scratching the top of pintle when pulling out the pin medicated cap with thumb, directly pulled out just, convenient and labor-saving.When pulling out pin medicated cap 1, with syringe 6 and pin medicated cap 1 past opposite direction rotation, the resistance between dependence pin medicated cap and the pintle vertical line is easy just to be pulled out syringe needle; Perhaps the operator is directly pinching the place that pintle has vertical line with hands, has increased the frictional force of finger and pintle, is easy to just syringe needle be pulled out.This design is convenient and labor-saving, can effectively reduce the probability of pricking wound in the clinical nursing activity, guarantees operator's safety, promotes operator's health.
Above example only is used for illustrating preferred implementation of the present utility model; but this utility model is not limited to above-mentioned embodiment; in the ken that described field those of ordinary skill possesses; any modification of doing within spirit of the present utility model and the principle, be equal to and substitute and improvement etc., it all should be encompassed within the technical scheme scope that this utility model asks for protection.
