This utility model mainly is that three-way valve is connected with piercing needle and one-way control valve dismountable are alive respectively.It has following advantage:

(1), puncture safety, accurate, reliable.This puncture needle before puncture in spicula go out the about 2mm of outer casing needle, in the piercing process because of the effect of site of puncture tissue resistance, interior pin shrinks in outer casing needle, and the elastic component of the interior needle handle end of compression, rely on the outer casing needle inserting needle this moment, when the needle point of outer casing needle enters cavity, because tissue resistance reduces suddenly, interior pin ejects outer casing needle under the effect of elastic component, return to the preceding state of puncture, the front end of piercing needle is flat-head shape, the pair damage that is caused in the time of preventing to puncture effectively, and can clearly point out puncture needle to enter cavity.When the thyrocricoid puncture of especially being expert at is ventilated fast, the sense that falls through of hands during puncture, the inserting needle scale mark of piercing needle in addition makes that puncture is more accurate, reliable, safety.(2), puncture is convenient, workable.When carrying out the pneumothorax puncture drainage, mating reaction by three-way valve and one-way control valve, can be with the unidirectional discharge of intrathoracic pneumatosis, need not external water-sealed drainage bottle, the complicated pneumothorax puncture drainage of making over is simplified to two steps that puncture-fix, and particularly more seems easy to use when the state of emergency or condition are simple and crude.

After puncturing successfully, by regulating three-way valve, can finish single, doublely to ventilation and biopsy, can finish drawing liquid, flushing, injection etc. by syringe.When the thyrocricoid puncture of being expert at is ventilated fast, after clearly puncturing successfully, three-way valve and one-way control valve can be removed, pin in extracting out with hole diameter enlargement, is beneficial to two-way ventilation.

(3), rational in infrastructure, easy and simple to handle, easy accessibility between each parts is convenient to clean, sterilization.

In a word, this puncture needle can combine together to ventilation, drain, flushing, injection, all functions of biopsy single, double fast, be applicable to that thyrocricoid puncture ventilates fast, the pneumothorax unidirectional ventilation of puncturing, breast, abdominal paracentesis drawing liquid or bleed, flushing, injection, placement conduit, biopsy etc.It integrates first aid, diagnosis, etiological treatment, can the many usefulness of a pin, both be easy to grasp, and easy and simple to handle, safe and reliable, convenient and practical, puncture quick and precisely can be avoided the unnecessary secondary damage of puncture effectively again, can be used for medical treatment at ordinary times, can be used for first aid wartime, easy to carry.
