Description

Double-balloon thrombus flushing and sucking catheter

Technical Field

The utility model relates to the field of medical equipment, in particular to a double-balloon thrombus flushing and sucking catheter.

Background

The thrombus aspiration is mainly divided into two types, one is to aspirate the thrombus by using a catheter, pass the catheter through the blood vessel to the inside of the thrombus, and aspirate the thrombus again, which is relatively inexpensive. The suction effect is mainly determined according to the diameter of the catheter, and if the catheter is thicker, the suction effect is better. The other is mechanical suction, a special thrombus suction device is provided, thrombus is also entered into the thrombus through a blood vessel, thrombolytic drugs are injected into the thrombus, the drugs dissolve the thrombus after standing for a period of time, and then the machine is opened to suck the thrombus dissolved to be soft out of the body through the machine.

The modes adopted by the thrombus aspiration in the prior art have certain defects, so a safe and efficient flushing and sucking catheter is needed to make up for the defects in the prior art.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model is implemented specifically, the double-balloon thrombus flushing and sucking catheter comprises a wire guide tube 1, wherein a wire guide hole 2 is formed in the end part of the wire guide tube 1, a first balloon 3 is arranged at one end, close to the wire guide hole 2, of the wire guide tube 1, a second balloon 4 is arranged on one side, far away from the wire guide hole 2, of the first balloon 3, a side hole 5 is formed between the first balloon 3 and the second balloon 4, and the side holes 5 are distributed on the wire guide tube 1 in an array mode.

As an improvement, the first balloon 3 and the second balloon 4 have the same size and are made of the same soft elastic material, and the soft elastic material can completely block the blood vessel and simultaneously can increase the safety and avoid damaging the inner wall of the blood vessel.

As an improvement, the wall of the guide wire tube 1 is a double-layer tube wall, a cavity is arranged in the guide wire tube, the cavity is connected with the first balloon 3 and the second balloon 4, and the balloons are inflated according to the diameter of the blood vessel to block the blood vessel.

As an improvement, the end parts, far away from the wire guide tube 1, of the first balloon 3 and the second balloon 4 are provided with planes, the inner walls of blood vessels can be better attached through the planar design, so that blockage is formed, and blood is prevented from losing in the flushing and sucking processes.
