Description

Movable equipment for preventing lower limb deep vein thrombosis

Technical Field

The utility model relates to the technical field of medical equipment, specifically a prevention deep vein thrombosis's of low limbs movable equipment.

Background

Deep venous Thrombosis (hereinafter DVT) refers to: in the deep venous blood vessel, blood coagulates or some visible components in the blood agglutinate to form a solid mass; the deep veins of the lower limbs are main access blood vessels which are responsible for conveying blood of the lower limbs to return to the heart, when the blood in the deep vein system is coagulated and forms thrombus due to various reasons, the blood of the lower limbs cannot smoothly return to the heart, a large amount of blood is remained in the lower limbs, the venous pressure is increased, and the extravasation of blood components occurs, so that the limb swelling and pain are caused, and the disease becomes the deep vein thrombus of the lower limbs.

In clinical surgery, the operation time is too long; damage to tissue and vessel walls from surgery; slow blood flow caused by anesthesia or extracorporeal circulation; a decrease in blood volume; surgical coagulation and fibrinolytic system imbalance; post-operative braking, etc., can lead to the development of DVT. The incidence of DVT after general surgery without preventive measures is reported to be about 15% to 30%; the incidence of DVT after the obstetric major surgery is equivalent to that of general surgery; while hip fracture, hip arthroplasty and knee arthroplasty are up to 48%, 51% and 61%, respectively. In addition, severe trauma causes tissue damage and vessel wall damage; trauma, blood loss, hypoxia as stressors activate the coagulation system; post-traumatic arrest and relative hypovolemia slow blood flow, both of which are associated with post-traumatic thrombosis. Wherein the incidence of DVT caused by trauma without any preventive measures is over 50%, and the incidence of DVT caused by spinal cord injury is as high as 60% -100%.

At present, two types of thrombus prevention methods are mainly available in the market, namely, taking anticoagulant drugs and preventing thrombus equipment or instruments such as medical elastic socks and the like, and the currently used measures for preventing postoperative deep veins of lower limbs have the following defects: after operation, anticoagulant drugs are taken, so that certain bleeding risk is caused, and the wound of a patient is not healed; the medical elastic socks are mainly suitable for people who stand for a long time to improve blood circulation, and are mainly used for clinically preventing venous embolism of postoperative long-term bedridden patients, so that the patients have more contraindicated objects, such as dermatitis on legs.

In view of the foregoing background, the present invention provides a mobile device for preventing deep vein thrombosis of a lower limb.
