Description

A device for preventing lower extremity venous thrombosis of obstetric pregnant women during pregnancy and postpartum

technical field

The invention belongs to the technical field of medical auxiliary appliances, and in particular relates to a device for preventing venous thrombosis of the lower extremities of pregnant and lying-in women in obstetrics during pregnancy and postpartum.

Background technique

Venous thrombosis is a disorder of venous return caused by abnormal coagulation of blood in the veins, mostly in the lower extremities. At present, the diagnosis of DVT mostly relies on color Doppler ultrasonography. The common symptoms of DVT patients are pain in the affected limb (92.34%), superficial varicose veins (32.57%), pigmentation (24.95%) and ulceration (18.45%). In the acute stage, swelling of the affected limb was the main manifestation, accounting for 97.24%. Swelling of the lower extremities is the main, or the only symptom. Pregnant women and the elderly are the main affected groups. Pregnant women often need to rest during pregnancy and postpartum, and their daily activities are reduced, which is likely to cause lower extremity venous thrombosis. Lower extremity venous thrombosis may lead to life-threatening complications such as pulmonary embolism, cardiac infarction, cerebral infarction, etc. Therefore, prevention of lower extremity venous thrombosis is particularly important. In the existing technical data, pregnant women are usually exercised by venous thrombosis prevention devices for lower extremity activities.
