Blocking device for lower limb deep venous thrombosis

Abstract

The invention discloses a blocking device for lower limb deep venous thrombosis, and relates to the technical field of medical apparatuses. The blocking device for lower limb deep venous thrombosis comprises a blocking tape and a bar-shaped air sac, wherein the blocking tape is a bar-shaped tape without elasticity, and joints devices are arranged at two ends of the blocking tape to form a ring; the bar-shaped air sac is mounted on the inner side of the blocking tape, and is used for inflating and deflating and detecting air sac pressure through an inflating and deflating pipeline on one side of the blocking tape; and a region which is not provided with the bar-shaped air sac, on the inner side of the blocking tape is stuffed with a flexible material. Through durable, effective and precisepressure control on superficial veins, superficial veins of lower limbs are blocked to the maximum extent, drugs directly achieve thrombosis positions to achieve the purpose of treatment, and besides,the blocking device has high comfortable degree and practicality and is suitable for popularization and use in medical institutions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blocking device for lower extremity deep vein thrombosis. Background technique [0002] Lower extremity deep vein thrombosis, also known as lower extremity deep vein thrombosis, is a common disease. It refers to the abnormal coagulation of blood in deep veins, blocking the lumen, and causing venous return disorders; the main veins of the whole body can be affected, especially the veins of the lower extremities. , and the left lower extremity is the most common, males are slightly more than females, can leave leg edema, secondary varicose veins, dermatitis, pigmentation, stasis ulcer, etc., if the lower extremity venous thrombosis is not treated in time, it will cause varying degrees of Chronic deep venous insufficiency, even disability, and pulmonary infarction caused by thrombus shedding in the acute stage are one of the common causes of clinical sudden death.

AI Technical Summary

Problems solved by technology

[0004] Thrombolysis, anticoagulation and depolymerization are the main methods of non-surgical treatment of deep venous thrombosis of lower extremities. Urokinase is the preferred thrombolytic drug, which directly acts on the endogenous fibrinolytic system to play a role in thrombolysis and treat newly formed thrombus. The effect is better, and at the same time, it can also inhibit the platelet aggregation induced by ADP and prevent thrombosis. Clinically, the superficial venous plexus that compresses the ankle joint is usually instilled with urokinase through the deep vein for drug thrombolysis. At the junction of the superficial venous plexus above the ankle, apply pressure to block the superficial veins and open the deep veins to the maximum extent, so that urokinase first passes through the thrombus site before passing through the body tissue, ensuring a higher drug concentration in the thrombus formation and exerting the maximum effect. Thrombolytic effect; however, the currently used yellow leather tube has a small force-bearing area, is difficult to precisely control the pressure, and is easy to fall off after long-term use, and will produce dark red indentations on the patient's ankle, which will bring pain to the patient. If the superficial vein cannot be blocked or the blockage is incomplete, it will affect the concentration of urokinase at the thrombus formation site, and it is difficult to achieve the therapeutic effect. At the same time, the control of the tightness during operation requires considerable experience and is not suitable for wide application.
