Further, described side opening axis is crossing with through-bore axis.
Further, described second side opening diameter is greater than the first side opening diameter.
Further, described needle handle is provided with seal groove.
Further, described seal groove is provided with sealing ring.
Further again, the diameter of described through hole is identical with the diameter of needle tubing.
Further, the diameter of described connecting hole is greater than the diameter of through hole and needle tubing.
Income effect: this utility model offers a side opening on the needle handle of arterial puncture needle, to be connected an obturator with spring at side opening, puncture successfully and bleed by obturator interruption artery, effectively overcome the of short duration blood ejection phenomenon that current technology occurs when puncturing pulse, be convenient to subsequent operation carry out calmly, to ensure inserting smoothly of the anti-dictorial advisor's pipe of aorta after balloon, simple to operate, cost is low, be easy to realize, have application value clinically.

Detailed description of the invention
Elaborate to embodiment of the present utility model below in conjunction with accompanying drawing, the present embodiment, premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1 and Figure 2, a kind of arterial puncture needle, comprise needle handle 1 and needle tubing 2, the through hole 3 communicated with needle tubing 2 is provided with in needle handle 1, described through hole 3 upper end is connected with the buffer memory pipe 6 of scale mark, when needle tubing 2 pierces through tremulous pulse, there is blood back can cushion in buffer memory pipe 6, as shown in Figure 4, needle handle 1 side is provided with the side opening 4 communicated with through hole 3, side opening 4 and through hole 3 axes intersect, and the diameter of side opening 4 is greater than the diameter of through hole 3, side opening 4 comprises the first side opening 402 and the second side opening 401, second side opening 401 diameter is greater than the first side opening 402 diameter.
As shown in Figure 3, with traditional arterial puncture needle unlike, also comprise obturator 5, described obturator 5 comprises one end and passes the first side opening 402 and the sliding axle 501 stretching out needle handle 1, sliding axle 501 other end connects the block 502 being positioned at the second side opening 401, the width of block 502 is greater than the width of the first side opening 402, block can be made to be in the second side opening 401 slide, sliding axle 501 one end of stretching out outside needle handle 1 is provided with a button 504, sliding axle 501 between outside button 504 and needle handle 1 is provided with the spring 8 for making button 504 reset, second side opening 401 is provided with seal groove 403 with the junction of sliding axle 501 outside needle handle 1, seal groove 403 is built with sealing ring 7, because the second side opening 401 is connected with through hole 3, and the diameter of the second side opening 401 is larger than the diameter of sliding axle 501, therefore arrange sealing ring 7 can effectively prevent from the moment of piercing through tremulous pulse, blood being oozed out.
As shown in Figure 2, the diameter of through hole 3 is identical with the diameter of needle tubing 2, and sliding axle 501 is also provided with a connecting hole 503 that the part between through hole 3 with needle tubing 2 is communicated, and the diameter of connecting hole 503 is greater than the diameter of through hole 3 and needle tubing 2.
During use, under the elastic force effect of spring 8, block 502 and spring 8 secure the position of sliding axle 501 jointly, connecting hole 503, the dead in line of through hole 3 and needle tubing 2, from top to bottom, buffer memory pipe 6, through hole 3, connecting hole 503, needle tubing 2 is all in the state communicated, now needle tubing inserts arterypuncture success, arterial blood can be gushed out and in buffer memory pipe 6, when blood arrives scale mark, arterial puncture needle is fixed with left hand, and press rapidly button 504 with left hand thumb and make its Compress Spring 8, as shown in Figure 5, sliding axle 501 moves and connecting hole 503 and needle tubing 2 is misplaced, blocking needle tubing 2 makes blood not gush outward with being communicated with of through hole 3, insert seal wire or conduit 9 this moment, when seal wire or conduit 9 arrive the position of sliding axle 501, release button, sliding axle 501 is made to drive connecting hole 503 to reset, seal wire or conduit 9 are smoothly by connecting hole 503 to intra-arterial.
This utility model is prior art for describing part.
