Abstract
The utility model belongs to the technical field of medical equipment and particularly relates to a device for preventing needle puncture, namely an anti-puncture medical needle. According to the technical scheme, the anti-puncture medical needle is characterized in that a seal cannula (4) for sealing a puncture needle when the puncture needle is removed and an elastic rubber plug (5) disposed at the front end of the seal cannula are arranged outside the traditional needle; during using, the puncture needle (1) can be removed and meanwhile is sealed by the elastic rubber plug (5), just by pressing a handle (8) on the seal cannula (4) and pulling back a hose (3). The anti-puncture medical needle has the advantages that the puncture needle is prevented from puncturing people, blood or liquid in the puncture needle can be prevented from splashing out, and the anti-puncture medical needle is simple in structure, low in manufacturing cost and convenient to use.
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly a kind of device that prevents needle sting.
Background technology
Hospital, in the treatments such as enforcement venous blood collection or transfusion, can be punctured to syringe needle in Venous Blood pipe, after treatment finishes, syringe needle is extracted.Existing related medical apparatus mostly is disposable products, syringe needle is furnished with a pin cap before use, before medical personnel have an acupuncture treatment, pin cap is taken off and pin cap is abandoned, syringe needle is extracted rear medical personnel discarded syringe needle part is lost into sharp instrument box, in the whole circulation process of medical waste, sharp needle point is always exposed, very easily causes the relevant people such as medical personnel, medical waste treatment people by needle sting; Even if pin cap does not abandon, because pin cap is very little, return in cover syringe needle process and be also very easy to stab medical personnel with these pin caps.These syringe needles are subject to blood contamination because penetrating patient vessel, if personnel can be caused the propagation danger of all kinds of blood born diseases by needle sting, even produce serious doctor source security incident.
Relate to the typical medical apparatus and instruments of this problem and have blood taking needle, transfusion device, puncture of internal arteriovenous fistula pin etc.Wherein puncture of internal arteriovenous fistula pin is for hemodialysis, because treatment need to reach the flow of 250 to 300 milliliters per minute, therefore syringe needle has the advantages that internal diameter is thick, whole dialysis pipeline has again extraordinary elasticity, if do not carry out shutoff after syringe needle pulls out, in the dismounting of venipuncture needle and syringe needle circulation process, very easily cause the blood and slime mixture in puncture needle to spill, cause unexpected nosocomial infection.
Utility model content
The purpose of this utility model is: a kind of medical needle of Anti-stabbing is provided, prevents needle sting human body, be applicable to the medical apparatus and instruments such as disposable blood taking needle, transfusion device, puncture of internal arteriovenous fistula pin.
The technical solution of the utility model is: a kind of medical needle of Anti-stabbing, comprise piercing needle, needle stand, flexible pipe, lever, and described syringe needle is fixed on described needle stand, and described needle stand is fixedly connected with described flexible pipe, and described lever is fixedly connected with described flexible pipe;
It is characterized in that: also comprise envelope needle cannula, elastic rubber plug, hands handle;
Described envelope needle cannula front end is provided with described elastic rubber plug, and described envelope needle cannula is arranged on outside described flexible pipe and matches and be flexibly connected with described flexible pipe, and described elastic rubber plug is arranged on described piercing needle afterbody through described piercing needle head;
Described envelope needle cannula is provided with breach, described breach from described lever, when its length will make described lever move backward described in elastic rubber plug seal described piercing needle;
Described handle is arranged on described envelope needle cannula front end, and is fixedly connected with described envelope needle cannula, is symmetrical arranged with described lever.
This utility model is provided with the envelope needle cannula of shutoff piercing needle when extracting piercing needle outward and is arranged on the elastic rubber plug of its front end at traditional syringe needle, as long as pin described handle when use, firmly pull back described flexible pipe can realize extract described piercing needle and simultaneously piercing needle sealed by described elastic rubber plug, realize and prevented that described piercing needle from stabbing personnel, and avoid blood and slime in described piercing needle to spill, simple in structure, cheap, easy to use.Can be used for the products such as medical blood-sampling needle, transfusion device, puncture of internal arteriovenous fistula pin.
