The retraction type Self-destroyed safety syringe of the utility model has the advantages that
1, the retraction type Self-destroyed safety syringe of the utility model, will at the needle stand being made of upper needle stand and lower needle stand
Infusion channel on lower needle stand is connected with catheter, makes needle stand and lower needle stand connectionless place in infusion process, knit stitch
Seat upper end is directly connected to syringe needle, and lower needle stand lower end is directly connected to syringe inner cavity, therefore has effectively blocked leakage situation when infusion
Occur, while also greatly simplifying the structure at needle stand, improves production efficiency.
2, it is perpendicular to add one for needle stand connector center of the retraction type Self-destroyed safety syringe of the utility model on push rod
To the expansion joint in prismatic shape, both needle stand connector can be made in pushrod advances in this way, the expansion joint in prismatic shape is being infused
It in channel and catheter suffers oppression and shrinks, operation when dropping bottom Self-destroyed safety syringe significantly in this way is exerted oneself, when losing
It plays after thrust and still and blocks the infusion channel of safety injector and the effect of catheter, and also mitigate health care workers'
Burden.
3, the retraction type Self-destroyed safety syringe of the utility model is additionally provided with a buckle at the side of push rod lower end, with
Increase the damping between push rod and syringe inner wall, prevent in operation preparation process, in syringe also without infusion when, in improper situation
Pushrod advances occur, makes to scrap safety injector after in needle stand connector insertion needle stand, causes unnecessary waste, then just
When being often used, buckle even root can be extractd.
The retraction type Self-destroyed safety syringe of the utility model is suitable for the application such as hospital.
