Description

Device for preventing deep vein thrombosis and foot drop

Technical Field

The invention relates to the technical field of medical treatment, in particular to a device for preventing deep vein thrombosis and foot drop.

Background

Venous Thromboembolism (VTE) includes a group of thromboembolic diseases including Deep Venous Thrombosis (DVT), pulmonary Embolism (PE) and postthrombotic syndrome, the deep veins of the lower limbs are main passage blood vessels which are responsible for transporting blood of the lower limbs to return to the heart, when the blood coagulates to form thrombus, the blood of the lower limbs cannot smoothly return to the heart, a large amount of blood is left in the lower limbs, the pressure of the veins is increased, and extravasation occurs, so that the limbs are expanded and painful, and the diseases are called as the deep venous thrombosis of the lower limbs. VTEs have a high incidence worldwide, with an average incidence of about 1.17% o, with about 34% of them appearing as a sudden lethal PE. VTE is a major cause of death, disability worldwide, and is also a significant cause of unintended death in patients in hospitals. The common diseases of hospitalized patients, frequently occurring in combination with other diseases, are a significant cause of unexpected death in hospitals, and have become a serious problem for hospital managers and clinical staff, therefore, in order to prevent deep venous thrombosis of lower limbs of patients, the patients need to apply compression force regularly outside the lower legs to squeeze blood vessels of the legs so as to accelerate blood circulation; when a patient suffering from cerebral apoplexy lying in bed for a long time is prone to deep venous thrombosis, the risk of foot drop is high, the foot drop causes one of the orthopedic signs, the patient sits, two lower limbs naturally hang, and if the foot is in a plantar flexion position and cannot actively dorsiflex, turn inwards and turn outwards at all, the foot drop is caused. Intrinsic can be seen in sciatic nerve paralysis and common peroneal nerve paralysis, which are intrinsic and can not dorsiflex nor plantarflex the toes; intrinsic to the latter, the toes can be plantarflexed; therefore, in order to prevent the foot drop of the patient, the blood vessels of the foot of the patient need to be squeezed by applying a compression force regularly outside the foot of the patient to accelerate the blood circulation and urge and guide the patient to irregularly perform the bare pump movement of the foot so as to keep the foot vitality.

In the prior art, when deep venous thrombosis of lower limbs of a patient is prevented, an instrument for preventing the deep venous thrombosis of the lower limbs of the patient is used, when the foot drop of the patient is prevented, the instrument for preventing the foot drop of the patient is used, namely when the deep venous thrombosis of the lower limbs of the patient and the foot drop are required to be prevented simultaneously, the two instruments cannot be used for the patient simultaneously, the instrument is required to be replaced, the operation is inconvenient, the cost is high, the two instruments cannot be used in a matched mode, the deep venous thrombosis and the foot drop can not be prevented more excellently, meanwhile, the pressure of the two instruments cannot be controlled, and the instrument cannot be adapted better.
