A thrombus suction system

Abstract

The invention discloses a thrombus suction system, which comprises a thrombus suction catheter and a blood bottle matched with it. The thrombus suction catheter in the present invention adopts ultra-thin tube wall, wide inner cavity and single-lumen pipeline design to ensure smooth and efficient thrombus suction. It enters the blood vessel as a whole to reduce the damage to the human body. The distal end is equipped with a spirally distributed elliptical side hole, which is convenient for the smooth suction of larger thrombus in the blood vessel, so as to prevent the situation that the larger thrombus cannot be sucked, so that the thrombus in the blood vessel The suction is complete to achieve the best therapeutic effect. The blood extracted from the human body during the operation flows into the blood bottle and passes through the thrombus filter in the bottle to filter out the extracted thrombus. The filtered blood can be re-infused into the human body, making the Autologous blood can be used quickly and effectively, avoiding adverse reactions such as contamination of patients by allogeneic blood.

Description

technical field [0001] The invention relates to a medical device, in particular to a thrombus suction system. Background technique [0002] Interventional medicine has been clinically applied for 30 years. It is an important treatment method in cardiovascular, cerebrovascular, peripheral vascular, tumor, or non-vascular fields. One of the diagnostic techniques. At present, the most widely used are cardiac interventional therapy, neurological interventional therapy, cerebrovascular interventional therapy, tumor, peripheral blood vessel and non-vascular lumen interventional therapy. [0003] With the accumulation of clinical data, the application value of thrombus aspiration catheter has gradually been recognized. At present, thrombus suction catheters with different structures have been developed in the international field to suck thrombus in the peripheral blood vessels of the human body. The injury caused a lot of inconvenience to the operation process, and the operation...

AI Technical Summary

Problems solved by technology

At present, thrombus aspiration catheters with different structures have been developed successively in the international field to aspirate thrombus in the peripheral blood vessels of the human body. The injury caused a lot of inconvenience to the operation process, and the operation effect was limited

[0004] At present, most thrombus aspiration catheters on the market use double-lumen tubes, which are the suction lumen and the guide wire lumen respectively. The guide wire lumen of some products is outside the suction lumen. The disadvantage of this design is that it increases the catheter Cross-sectional area; some products have guide wire lumen inside the suction lumen and only have one suction hole at the head end, which limits the ability of the catheter to suck thrombus

[0005] During interventional treatment, only the thrombus suction catheter is used to suck out the thrombus in the peripheral blood vessels of the human body, and at the same time, a large amount of blood is sucked out, so that it is necessary to send allogeneic blood to the patient to replace the lost blood, which may cause Pollution and other adverse reactions, and for patients, the cost of allogeneic blood is also high
