Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Fig. 1, Fig. 2 and Fig. 3 schematically show a kind of embodiment of this utility model new type nerve blockage puncture pin.As depicted in figs. 1 and 2, comprise needle tubing 1, needle point 2, square needle stand 3 and built-in nook closing member 4, needle tubing 1 is one-body molded with square needle stand 3; Square needle stand 3 is convenient to hold.As shown in Figure 2, needle point 2, in coniform, make this puncture needle passivity separately to organize instead of sharp keen incision, reduces neural probability of stabbing cut-out in inserting needle process; Needle point 2 outer wall is distributed with 6 side openings, 5,6 side openings 5 and is distributed on six faces being formed of conical base circle six deciles respectively, and 6 side opening 5 interleaved arrangements, so that medicinal liquid injects and is uniformly distributed.
Square needle stand 3 is provided with square needle stand groove 6; Described new type nerve blockage puncture pin also comprises square needle cap 12, the bottom of square needle cap 12 is provided with the pin cap projection 13 matched with square needle stand groove 6, square needle cap 12 realizes the fixing of square needle cap 12 and square needle stand 3 by being embedded in needle stand grooves 6 by pin cap protruding 13, thus built-in nook closing member 4 is placed in needle tubing 1, and the tip of built-in nook closing member 4 is coniform, closely agree with needle point 2, ensure to block side opening without blood, fine tissue in piercing process.
Needle tubing 1 is provided with cuff 7, and needle tubing 1 sidewall is provided with a logical gas/liquid pipe 8, and cuff 7 communicates with logical gas/liquid pipe 8, and the afterbody of logical gas/liquid pipe 8 is provided with check valve 9.As shown in Figure 3, square needle stand 3 connects PVC extension tube 10, PVC extension tube 10 one end by thread connecting mode and is connected with needle tubing 1 end, and the other end is provided with the interface 11 be connected with syringe.
