Technical Field

[0001] The invention relates to the technical field of body positioning pads, and in particular to a multifunctional body positioning pad for preventing deep vein thrombosis of lower limbs. Background Art

[0002] Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Currently, VTE has become the third most common cardiovascular and cerebrovascular disease after ischemic heart disease and stroke. VTE has a high incidence and mortality rate, and effective prevention can significantly reduce the mortality rate. Deep vein thrombosis is a common complication of hospitalized bedridden patients. It refers to the coagulation of venous blood in the deep veins of the lower extremities. This disease can leave behind limb edema, secondary varicose veins, dermatitis, pigmentation, stasis ulcers, etc. There are many reasons for blood stasis, such as long-term immobilization, bed rest due to illness, long-term sitting, varicose veins, etc. Spinal anesthesia or general anesthesia during surgery causes peripheral venous dilation and slows venous flow. During surgery, the anesthetic effect causes complete paralysis of the lower limb muscles, resulting in loss of contraction function. After surgery, the patient is bedridden due to incision pain and other reasons, and the lower limb muscles are in a relaxed state, resulting in slow blood flow and inducing deep vein thrombosis of the lower limbs. Pulmonary plunger caused by deep vein thrombosis of the lower limbs is a major threat to human life safety, and slow venous blood flow, hypercoagulable state of blood and damage to the venous vessel wall are the three main causes of deep vein thrombosis.
