Four, description of drawings
The three-dimensional structure diagram that Fig. 1 links together for each parts of this utility model.
User mode figure when Fig. 2 plays protection for this utility model puncture back safety helmet.
Section partial enlarged drawing when Fig. 3 is safety helmet of the present utility model and puncture needle work.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Provide by Fig. 1 to Fig. 3, this utility model comprises needle stand, puncture needle, flexible pipe seat, anti-overflow plug and flexible pipe, be set with flexible pipe 6 through rivet 5 on the flexible pipe seat 4, there is the sheath 8 that is inserted on the flexible pipe seat 4 flexible pipe 6 outsides, anti-overflow plug 3 is arranged in the flexible pipe seat 4, and safety helmet 2 is arranged at the bottom of anti-overflow plug 3, and puncture needle 7 one ends are fixed on the needle stand 1, the other end passes safety helmet 2 and anti-overflow plug 3 places in the flexible pipe 6, and transfusion threeway 11 and flexible pipe seat 4 link together through transfusion catheter 9.
In order to guarantee result of use, said safety helmet 2 is the hollow shells that are made of the software baffle plate 13 in rigid plastics shell 12 and the shell.
On the said transfusion catheter 9 flow-stopping clip 10 is arranged.
When this utility model uses; pull out sheath 8; after medical personnel give the correct puncture of patient; flexible pipe 6 is incorporated in the blood vessel of human body; pinching needle stand 1 then extracts puncture needle 7 in human body; flexible pipe 6 just is trapped in the blood vessel of human body; when the blood back groove on the puncture needle 7 moves to the software baffle plate of safety helmet 2; software baffle plate on the safety helmet 2 just enters in the blood back groove; thereby safety helmet 2 is produced a kind of pulling force, safety helmet 2 is pulled out in flexible pipe seat 4, this moment, the needle tip of puncture needle 7 just was hidden in the safety helmet 2 completely; thereby safety helmet 2 has just played protective effect, has prevented the injury to medical personnel.
