Preferably, the fixed plate is internally provided with a needle head through hole matched with the needle head and an extrusion plate through hole matched with the extrusion plate in a penetrating manner respectively.
Preferably, the interior of the puncture-proof ring is provided with a return spring, and the return spring is respectively and fixedly connected with one side of the connector and the fixing plate.
Preferably, the needle head, the puncture-proof ring and the extrusion plate are distributed from inside to outside in sequence, and each extrusion plate is movably connected with the puncture-proof ring.
Preferably, the fixing plate is circular, and the through holes of the adjacent extrusion plates are positioned at two symmetrical sides of the through hole of the needle head.
Advantageous effects
Compared with the prior art, the utility model provides a prevent stabbing blood taking needle possesses following beneficial effect:
1. the puncture-proof blood taking needle extrudes the blood taking needle into the reagent kit through the connecting head by mutually sticking one end of the fixing plate and the inlet end of the reagent kit, in the extrusion process, the needle head can pass through the needle head through hole in the fixing plate, so that the needle head can smoothly enter the kit, and when in extrusion, the puncture-proof ring and the return spring inside the puncture-proof ring are also extruded, the return spring can contract and shorten in the puncture-proof ring until the extrusion plates pass through the extrusion plate through holes in the fixed plate to extrude the two adjacent extrusion plates mutually, the extrusion plate can touch the puncture-proof ring, the puncture-proof ring and the return spring stop moving along with the increase of the force application of the extrusion plate, after the blood sampling is finished, the extrusion plate is released, and the needle retracts due to the elasticity of the return spring, so that the needle safety effect of the blood sampling needle is achieved.
2. This prevent stabbing blood taking needle through being connected between fixed plate and the kit to and the syringe needle is in when not using and prevents stabbing the ring surrounding state, can prevent that the syringe needle from hindering the user by mistake.
