Abstract
The utility model discloses a bicavity puncture needle comprising a needle holder and a needle, wherein, the inside of the needle holder is provided with a lead flow cavity, the inside of the needle is provided with a cavity, the needle holder is connected with the needle, the lead flow cavity is communicated with the cavity, a godet conduit with the structure of the bending pipe is arranged on the side wall of the needle holder, and the inside of the godet conduit is provided with a cavity. The utility model has two relatively independent cavities, and the entrance directions of the two cavities are nearly perpendicular, so the problems that the manpower is wasted due to the simultaneous operation of two persons of the prior art and the puncture position is not easy to judge can both be solved.
Description
Technical field:
This utility model relates to a kind of medical instruments, is a kind of two-chamber puncture needle.
Background technology:
At present, the domestic existing angiographic neeclle has two kinds of single-chamber type and bicavates, but there is following shortcoming in the single-chamber type puncture needle: 1, when one man operation, often occur advancing seal wire on one side,, cause puncture needle adherent Yi Bian advance the phenomenon of puncture needle, seal wire can not intravasation problem, thereby, need another people's delivery guidewire, so caused the manpower waste.2, behind the puncture needle intravasation,, need to extract out seal wire usually when pushing seal wire when meeting resistance, to judge whether intravasation chamber of puncture needle, judge errorless after, send into seal wire more again, thus, both caused waste of time, cause patient's relative severe loss of blood again; Severe patient also can cause local hematoma.And existing two-chamber puncture needle so also there is difficulty of one man operation, needs another people's delivery guidewire, the waste of manpower problem of resource because the Way in of two-chamber is almost parallel.
Summary of the invention:
The purpose of this utility model is, a kind of two-chamber puncture needle is provided, and it has two relatively independent cavitys, and the Way near normal of two cavitys, so can solve the problem that need two people operate waste of manpower simultaneously and difficult judgement puncture needle stings the implantation site that prior art exists.
The purpose of this utility model is achieved through the following technical solutions: the two-chamber puncture needle, it has needle stand and syringe needle, be provided with drainage lumens in the needle stand, be provided with cavity in the syringe needle, needle stand is connected with syringe needle, and drainage lumens communicates with cavity, on the sidewall of needle stand wire catheter is installed, wire catheter is a bend pipe structure, is provided with cavity in the wire catheter.
For further realizing the purpose of this utility model, can also realize by the following technical solutions: the cavity of wire catheter is connected with the cavity of needle stand and becomes V font structure.The Way in of wire catheter departs from axis direction 90 degree of needle stand.
The beneficial effects of the utility model: when 1, it can avoid one man operation, the bad habit of seal wire was advanced on inserting needle limit, limit; 2, the internal diameter of wire catheter is identical with the seal wire diameter, make the seal wire of sending into be difficult for skidding off, and wire catheter is the bend pipe shape, make that contact point increases between seal wire and the wire catheter, can further strengthen the resistance between seal wire and the wire catheter, seal wire is more difficult to skid off from wire catheter thereby make; 3, needle stand is made by transparent plastics, is convenient to observe the degree that seal wire enters, thus can be under the situation that not exclusively withdraws from seal wire, and observing has no blood in the drainage lumens.
Description of drawings:
Accompanying drawing is this utility model structural representation.
The specific embodiment:
The two-chamber puncture needle, it has needle stand 2 and syringe needle 3, is provided with drainage lumens 6 in the needle stand 2, be provided with cavity 4 in the syringe needle 3, needle stand 2 is connected with syringe needle 3, and drainage lumens 6 communicates with cavity 4, wire catheter 1 is installed on the sidewall of needle stand 2, and wire catheter 1 is a bend pipe structure, is provided with cavity 7 in the wire catheter 1.The cavity 7 of wire catheter 1 is connected with the cavity 4 of needle stand 2 and becomes V font structure.The Way in of wire catheter 1 departs from axis direction 90 degree of needle stand 2.Wire catheter 1 of the present utility model and needle stand 2 can be made into one.When this utility model is made, process each parts and assembling by above-mentioned requirements.The interior diameter of wire catheter 1 of the present utility model can be identical with the diameter of seal wire 5, skids off from wire catheter 1 to prevent seal wire 5; Wire catheter 1 is the bend pipe shape, makes that contact point increases between seal wire 5 and the wire catheter 1, and the resistance that has increased between seal wire 5 and the wire catheter 1 prevents that further seal wire 1 from skidding off from wire catheter 1.Needle stand 2 of the present utility model can be made with transparent rigid plastics, so that observe the degree that seal wire 5 enters.When this utility model uses, at first seal wire 5 is inserted wire catheter 1, but do not enter cavity 4; Again puncture needle is sent into blood vessel, see when having blood flow to go out in the cavity of puncture needle, again seal wire 5 is sent into blood vessel; At last, extract puncture needle and finish the whole operation process.
