Description
This utility model relates to a kind of safety device, particularly a kind of entry needle safety device.
One of utensil that extensively adopts when entry needle is the injection of all medical institutions because it is and the subcutaneous utensil that directly contacts with blood of human body, thereby also is one of main path of infection various diseases, for example: hepatitis A, hepatitis B, AIDS etc.Though some big institutes of traditional Chinese medicine have adopted the blood drawing disposable aspiration needle, but can't accomplish this point in vast rural area and infirmary, and injection or the syringe needle used when having an intravenous drip be not disposable aspiration needle, and what adopt is the reusable method in sterilization back, but not thorough because of sterilization sometimes, still do not carry disease germs unavoidably.So, people have adopted a kind of protection mode, referring to Fig. 9, promptly at hard protection cover 40 of syringe needle 50 outside retaining rings, time spent pulls out, with after put, preventing syringe needle and human body or contacting of other implements on every side, with reduce to user and medical personnel because of stabbing the incidence rate of the communicate illness that causes.But because syringe needle is an elongated body of rod, it is careful still to be careful when the suit sheath, otherwise also handwritten visiting card can be hindered, and in addition, is difficult for carrying out rapidly and accurately fit.In addition, because of sheath and needle tubing front end be movable sleeve insert detachable, maybe should protect careless and lose so still easily bump behind the fit to take off, it is undesirable to add result of use, so can not popularize use in an all-round way.So the accident that infects because of syringe needle still takes place again and again.
This utility model purpose just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and provides a kind of easy to use, and is safe and reliable, the entry needle safety device that is difficult for losing.
The purpose of this utility model is to realize by following technical scheme, needle tubing leading portion and back guard housing cover card connection, the front portion of back guard housing and front protection cover movable set, the cover pocket has a telescopic rubber sleeve between back guard housing and front protection cover, syringe needle is outer stretched mode by the pin hole at back sheath and front protection cover center, be with sheath at the front protection cover leading portion, by the push-and-pull front protection cover, the rubber sleeve that cover is trapped among between front protection cover and the back guard housing stretches or withdrawal automatically vertically, make the front protection cover that is connected with rubber sleeve along needle shaft to stretching can be cladded or be collected within the front protection cover so that expose syringe needle.With guarantee operating process and finish using after safety.
Therefore remarkable result of the present utility model is:
1. have and screen syringe needle and take off the effect of revealing syringe needle as required, can reach the purpose of guaranteeing security protection.
2. because of being with telescopic gum elastic cover between front protection cover and the back guard housing, so active front protection cover can not come off.
