Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to an anti-deep vein thrombosis instrument.
Background
Because the backflow of the deep venous blood is not smooth, a part of blood can flow back through the superficial vein, so that the superficial vein is over-relaxed, a patient feels swelling and pain, and deep venous thrombosis is likely to be formed in the past, and serious consequences are caused. Deep venous thrombosis mainly occurs when a human body is in a static state for a long time, and particularly after a major orthopedic surgery, the blood viscosity of a patient is increased and the blood resistance of lower limbs is increased due to the long-time resting recovery, so that blood is abnormally coagulated in a deep vein to form thrombus. After the thrombus is formed, most of the thrombus can be spread to the trunk of the deep vein of the whole limb, the blood backflow is blocked, and partial blood can flow back from the shallow vein, so that a patient can feel swelling and pain; if the effective treatment is not available for a long time, serious patients can even die by pulmonary embolism.
Antithrombotic pressure pumps (also called air pressure wave therapeutic apparatus, circulation pressure therapeutic apparatus, gradient pressure therapeutic apparatus, four limbs circulation apparatus) widely used in hospitals are a rehabilitation medical apparatus which can extrude and massage limbs in large area according to the periodic inflation principle, increase venous blood flow of patients with venous thrombosis risk, greatly improve blood flow speed, reduce blood stasis and achieve the purpose of preventing deep venous thrombosis and pulmonary embolism, and are mainly used for clinical treatment of patients. The antithrombotic pressure socks widely used in the market are convenient to carry and low in manufacturing cost, but the continuous pressure gradient provided by the antithrombotic pressure socks is only beneficial to venous blood backflow and not beneficial to arterial blood flow, and patients feel uncomfortable after long-term use. Although there are many portable antithrombotic instruments on the market at present, the principle is mostly to utilize pneumatic means to realize pressure gradient, so it needs the air pump to realize, if adopt little air pump then can't realize quick response and ideal pressure gradient, and adopt big air pump can produce very big noise, influence user's rest, and carry inconvenient.
