Description

A therapeutic instrument for preventing thrombosis

technical field

The invention relates to the technical field of anti-thrombosis therapeutic apparatus, in particular to an anti-thrombotic therapeutic apparatus.

Background technique

The method of physical therapy and prevention of deep vein thrombosis is to use the air wave pressure therapy device to inflate, squeeze, and deflate in an orderly and rhythmic manner through the multi-cavity inflatable air bag, forming a cyclic pressure on the limb tissue and oppressing the patient. Massage the muscles of the lower limbs while massaging the muscle tissues of the treatment area. After intermittent pressurization, the return speed of venous blood and lymph fluid will be accelerated, and the congestion in the veins of the lower extremities will also be reduced, so the pressure on the venous vessel walls and valves will also be reduced, so as to prevent deep vein thrombosis purpose of the disease.

The air wave pressure therapy instrument provides pressure from the outside of the human body through the air bag. The external pressure will inevitably cause damage to the muscles and tissues in the human body. The fat content is different. If the softness is different, excessive pressure will damage the muscles and tissues of the limbs, or even have the opposite effect. Smaller pressure may not achieve the effect of prevention and treatment. The air wave pressure therapy instrument uses air pumps and air valves to achieve The limb sleeve is inflated and deflated, so the time of inflation and deflation is very slow, it is difficult to be consistent with the pulse fluctuation, and it will even hinder the normal flow of blood and increase the pain of the person. At the same time, because the air wave pressure therapy device uses an air pump The air valve control produces noise during work, such as the hum of the air pump and the click of the air valve, which will affect the normal rest of the patient, especially the patient who just got off the operating table needs to rest quietly.
