Utility model content
The purpose of this utility model injects pressure to control injection, and ensure injection safety, and spy provides a kind of safety injector of automatic control injection pressure.
This utility model provides a kind of safety injector of automatic control injection pressure, it is characterized in that: the safety injector of described automatic control injection pressure, comprises syringe needle 1, needle tubing 2,3 are overlapped after needle tubing, piston 4, straight pin 5, spring 6, scale mark 7, sleeve 8, strip cannelure 9, transverse groove 10;
Wherein: syringe needle 1 is connected with the nose threads of needle tubing 2 or buckle connects; Overlap 3 after needle tubing to be threaded with needle tubing 2 rear end or buckle is connected, piston 4 is arranged in needle tubing 2; The afterbody of piston 4 is laterally fixedly connected with straight pin 5, and overlap the side of 3 after needle tubing with strip cannelure 9, the top position of strip cannelure 9 is with transverse groove 10; Be threaded connection, with scale mark 7 on sleeve 8 between overlapping 3 after sleeve 8 and needle tubing; Spring 6 is installed between sleeve 8 and piston 4.
Described strip cannelure 9 and transverse groove 10 are two, are arranged symmetrically with.
Described straight pin 5 is two, is arranged symmetrically with.
Described spring 6 is 1 or 2.
The straight pin 5 on piston 4 top can slide up and down along strip cannelure 9, and makes straight pin 5 be stuck in transverse groove 10 on top by rotary-piston 4, and when injecting, rotary-piston 4 makes straight pin 5 throw off transverse groove 10, and piston 4, under the promotion of spring 6, is injected rapidly.By turnbarrel 8, the distance between adjustment and piston 4, the pressure of regulating spring 6, and then pressure is injected in adjustment.
Advantage of the present utility model:
The safety injector of automatic control injection pressure described in the utility model, theory structure is simple, and during medicine injection, syringe needle and needle tubing nipple junction are not easily thrown off.Meanwhile, inject pressure adjustable control, can reach and at the uniform velocity advance, do not affect by operator's professional skill, easy to use, improve nursing procedure safety.The research and development of this kind of syringe, can make nursing procedure more rigorous, avoid operate in nurse by rule of thumb with sensation injection problem.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, this utility model is described in further detail:
Fig. 1 is the safety injector structural representation automatically controlling injection pressure.
