Problems solved by technology

[0004] Due to the limitation of insufficient performance of the device, thrombus aspiration cannot recover the blood in the thrombus-blood mixture. At present, none of the existing thrombus aspiration devices can return the "suctioned blood" to the patient, resulting in thrombus The amount of blood loss is too large during the aspiration process; and there is no automatic suction power during the thrombus aspiration process. The current thrombus aspiration can only rely on the syringe to provide suction power, and the power that the syringe can provide is neither quantifiable nor effective. continuity

Abstract

The invention relates to a thrombus filtration and recovery device. The device comprises a bottle body, wherein an input tube and a suction tube are arranged at the top of the bottle body, and the suction tube is connected to a negative pressure source; an output tube is arranged at the bottom of the bottle body; and a filtration mechanism is arranged inside the bottle body. The device disclosed by the invention can be used for effectively filtering blood in a suction part and can be used for promoting the blood, obtained from thrombus filtration, to flow back into a human body, so as to avoid an ischemia phenomenon in a patient during a long-term operation.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a thrombus filtration and recovery device. Background technique [0002] Venous thrombosis Blockage of veins is a common venous disorder. The disease can occur anywhere in the venous system, with the deep veins of the lower extremities being the most common, followed by the inferior vena cava. The disease is extremely harmful to the patient. Thrombus shedding into the pulmonary artery can cause fatal pulmonary embolism; and thrombus remaining in the deep vein of the lower extremity for a long time can cause post-thrombotic syndrome. It has been clinically proven that early treatment and thorough removal of thrombus are the core means of treating venous thrombosis. [0003] In the prior art, methods for treating venous thrombosis include: phlebotomy and thrombectomy, intravenous catheter thrombolysis and venous thrombus aspiration. Phlebotomy and thrombectomy can remove most of t...
