Abstract

The invention relates to the field of medical devices, in particular to a thrombus prevention and treatment catheter which comprises an indwelling catheter. The indwelling catheter comprises an inner catheter and an outer catheter; the outer catheter sleeves the inner catheter; spaces between the inner catheter and the outer catheter are filled with anticoagulants, and the anticoagulants can be outwardly permeated via the outer catheter. The thrombus prevention and treatment catheter has the advantages that hollow gaps are reserved between the inner catheter and the outer catheter of the indwelling catheter and are filled with the anticoagulants, the anticoagulants can be slowly released into the blood of patients via the outer catheter at certain speeds when the thrombus prevention and treatment catheter is used, and accordingly the purposes of preventing and treating thrombus can be achieved; the concentration of the filled anticoagulants can be regulated if the patients already suffer from the thrombus, or the release speeds of the anticoagulants can be regulated, so that the purpose of thrombolytic therapy can be achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a catheter for preventing and treating thrombosis. Background technique [0002] A thrombus is a small piece of blood that forms on the surface of a vessel in the cardiovascular system where the lining has been peeled off or repaired. In the variable fluid-dependent form, the thrombus consists of insoluble fibrin, deposited platelets, accumulated leukocytes, and trapped erythrocytes. [0003] Thrombosis is a multifactorial change process in which a group of genetic and environmental factors interact and influence each other. Among them, venous thrombosis is mostly caused by environmental factors. [0004] Venous thrombosis refers to a disease in which acute non-suppurative inflammation occurs in veins and secondary thrombosis occurs under the conditions of sluggish venous blood flow, blood hypercoagulability, and vascular intima injury. The vast majority of venous thrombosis o...
