Description

Artery suction catheter

Technical Field

The utility model belongs to the technical field of the artery suction pipe, concretely relates to artery suction pipe.

Background

Thrombi are small patches formed by the surface of blood flow within the vascular system at the site of denudation or repair, and in the variable fluid-dependent type, are composed of insoluble fibrin, deposited platelets, accumulated white blood cells and entrapped red blood cells. At present, the method for treating thrombus mainly comprises a medicinal antithrombotic treatment method and an artificial mechanical method for physically restoring the unobstructed blood vessel, but because the concentration of thrombolytic anticoagulant medicaments entering the blood vessel cannot be too high, otherwise, side effects and toxicity are generated on a human body, and simultaneously because the medicaments are metabolized and discharged in the human body, the concentration of the antithrombotic medicaments existing in the blood vessel is lower, and the antithrombotic treatment by the antithrombotic medicaments has the defects of slow action effect and the like, and the method cannot be used for rescuing acute thrombotic diseases such as acute myocardial infarction, cerebrovascular infarction, acute lower limb deep vein embolism and the like, and for the diseases, only a physical thrombus removal method can be adopted.

Thrombus aspiration catheters are available in the market at present, wherein the thrombus aspiration catheters are used for aspirating soft emboli and new thrombus generated in coronary arteries, and can slow down thrombus, block blood flow, recover blood supply, and avoid problems of acute myocardial infarction and the like. At present often use thrombus suction catheter to administer the thrombus and dissolve, again with the thrombus suction, the catheter front end opening is big when dosing at present, it is inconvenient to administer, in addition, suction catheter is at the suction thrombus in-process, some thrombus fragments can flow to the blood vessel distal end along with the blood flow to arouse distal end thromboembolism, can't be clean with the thrombus fragment suction, lead to the inefficiency of suction, complex operation increases operation time, and the treatment of influence operation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an artery suction catheter to there is the inefficiency of thrombus suction among the solution prior art, complex operation's problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an artery suction catheter, includes the pipe body, the one end of pipe body is connected with luer connector, luer connector's one end is connected with the three-way valve, the one end of three-way valve is connected with the negative pressure gasbag, the other end of three-way valve is connected with the pipe of dosing, luer connector is provided with the check valve, be equipped with a plurality of micropores of dosing on the check valve, the one end of pipe body is connected with the injection pipe, be equipped with the diffluence hole on the injection pipe, the other end of injection pipe is equipped with the mainstream hole, be provided with the control tube on the pipe body, the interlude has the commentaries on classics silk in the control tube, the one end of commentaries on classics silk is provided with rotatory handle.

Preferably, one end of the medicine injection tube is of a semicircular arc structure with the diameter gradually reduced.

Preferably, the outer walls of the catheter body and the operating pipe are provided with anti-backflow caps.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a femoral artery or radial artery puncture, insert the injection tube, the pipe body and the control tube artery, reach the thromboembolism position, the control three-way valve, open the one end of connecting the administration pipe, inject the thrombolytic medicine into the pipe body through the administration pipe, the thrombolytic medicine reaches the injection pipe through the administration micropore, and reach the thrombus through main discharge orifice and reposition of redundant personnel hole, dissolve the thrombus with higher speed, and insert the one end that the rotatory silk was worn out the control tube into the thrombus simultaneously, then control rotatory handle and drive the rotation of rotatory silk and smash the operation to the thrombus, after the thrombus is smashed and is accomplished, take out the rotatory silk, then control three-way valve closes the connection of administration pipe, and open and negative pressure gasbag link, under the suction effect of negative pressure gasbag, the thrombus fragment gets into the injection tube through main discharge orifice, and reach in the pipe body through the check valve, finally flow into the negative pressure gasbag and collect, the pipe cavity is prevented from being blocked by massive thrombus, so that the thrombus suction process is interrupted, then the catheter body is slowly moved until partial blood is sucked in the negative pressure air bag, the catheter body and the operating tube are quickly drawn out to complete the thrombus suction operation, the operation is more convenient and quicker, and the operation complications are reduced.
