Description

A kind of arterial puncture needle

Technical field

The present invention relates to technical field of medical instruments, particularly a kind of arterial puncture needle.

Background technology

Arterypuncture is the treatment means of commonly using clinically, arterial puncture needle used clinically now, especially the interior arterial puncture needle of IABP pump block dress is without control knob, after arterypuncture success, effectively interruption artery blood flow ejection in subsequent operation process, cause sheet to pollute, patient loses blood, cause patient and family members' fear, strengthen puncture risk, even may increase the weight of because losing blood conditions of patients, arterypuncture is after especially intraaortic balloon pump implantation arterial puncture needle is inserted, before placement seal wire, because of arterial pressure high, often cause arterial blood ejection, Qing Ze pollution resistant bed unit, heavy cause patient and lose blood, increase the weight of the state of an illness.

Summary of the invention

There is this problem for solving in above-mentioned technology, the invention provides and a kind ofly after arterypuncture success, can control the arterial puncture needle that prevents from spraying blood.

The present invention is for solving the problems of the technologies described above, the technical scheme adopting is: a kind of arterial puncture needle, comprise needle handle and needle tubing, in needle handle, be provided with the through hole communicating with needle tubing, described through hole upper end is connected with the buffer memory pipe of scale mark, described needle handle side is provided with the side opening communicating with through hole, side opening comprises the first side opening and the second side opening, also comprise obturator, described obturator comprises that one end passes the first side opening and stretch out the sliding axle of needle handle, the sliding axle other end connects the block that is positioned at the second side opening, the width of described block is greater than the width of the first side opening, one end that sliding axle stretches out outside needle handle is provided with a button, sliding axle between button and needle handle outside is provided with the spring for making push-button reset, on sliding axle, be also provided with a connecting hole that through hole is communicated with needle tubing, under External Force Acting, make button compress or become flexible under two states, drive sliding axle to block or be communicated with being connected between needle tubing and through hole.

Further, described side opening axis is crossing with through-bore axis.

Further, described the 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: the present invention offers a side opening on the needle handle of arterial puncture needle, at the connected obturator with spring of side opening, after puncturing successfully, can bleed by obturator interruption artery, effectively overcome the of short duration blood ejection phenomenon that current technology occurs in the time of puncture pulse, being convenient to subsequent operation carries out calmly, to ensure inserting smoothly of aorta after balloon anti-dictorial advisor's pipe, simple to operate, cost is low, be easy to realize, and has clinically application value.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, the present embodiment, taking technical solution of the present invention as prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention 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, in needle handle 1, be provided with the through hole 3 communicating with needle tubing 2, described through hole 3 upper ends are connected with the buffer memory pipe 6 of scale mark, in the time that needle tubing 2 stings perforating arteries, there is blood back in buffer memory pipe 6, to cushion, as shown in Figure 4, needle handle 1 side is provided with the side opening 4 communicating 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 that the first side opening 402 and the second side opening 401, the second side opening 401 diameters are greater than the first side opening 402 diameters.

As shown in Figure 3, different from traditional arterial puncture needle is, also comprise obturator 5, described obturator 5 comprises that one end passes the first side opening 402 and stretch out the sliding axle 501 of needle handle 1, sliding axle 501 other ends connect the block 502 that is positioned at the second side opening 401, the width of block 502 is greater than the width of the first side opening 402, can make block slide in the second side opening 401, one end that sliding axle 501 stretches out outside needle handle 1 is provided with a button 504, sliding axle 501 between button 504 and needle handle 1 outside is provided with the spring 8 for button 504 is resetted, the second side opening 401 is provided with seal groove 403 with sliding axle 501 near the junction in needle handle 1 outside, sealing ring 7 is housed in seal groove 403, 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 sealing ring 7 is set can effectively prevent from the moment of thorn perforating arteries, blood being oozed out.

As shown in Figure 2, the diameter of through hole 3 is identical with the diameter of needle tubing 2, is also provided with a connecting hole 503 that the part between through hole 3 and needle tubing 2 is communicated on sliding axle 501, and the diameter of connecting hole 503 is greater than the diameter of through hole 3 and needle tubing 2.

When use, under the elastic force effect of spring 8, block 502 and spring 8 have been fixed 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 the state in communicating all, now needle tubing inserts arterypuncture success, arterial blood can be gushed out and in buffer memory pipe 6, in the time that blood arrives scale mark, with the fixing arterial puncture needle of left hand, and make its Compress Spring 8 with the rapid pressing button 504 of left hand thumb, as shown in Figure 5, sliding axle 501 moves connecting hole 503 and needle tubing 2 is misplaced, blocking needle tubing 2 can not gush outward with making blood being communicated with of through hole 3, insert seal wire or conduit 9 this moment, in the time that seal wire or conduit 9 arrive the position of sliding axle 501, release button, make sliding axle 501 drive connecting hole 503 to reset, seal wire or conduit 9 pass through connecting hole 503 smoothly to intra-arterial.

The present invention is prior art for narrating part.
