System for preventing lower limb deep venous thrombosis and using method thereof

Abstract

The invention relates to a system for preventing lower limb deep venous thrombosis, which comprises a controller, and the first side surface of the controller is provided with an ultrasonic wave emitting electrode for emitting ultrasonic waves and an ultrasonic wave receiving electrode for receiving ultrasonic wave echoes; the binding belt is arranged on the first side face of the controller, the electrode plate is arranged on the side face, back to the controller, of the binding belt and electrically connected with the controller, and the binding belt is used for enabling the electrode plate to be tightly attached to the muscle of the stimulation site; the controller is used for applying pulse voltage to the electrode plate, so that the electrode plate generates current stimulation on muscles, ultrasonic waves are emitted to blood vessels of stimulation sites through the ultrasonic wave emitting electrode, then the blood flow speed is calculated according to ultrasonic wave echoes received by the ultrasonic wave receiving electrode, and the blood flow speed is compared with a preset first threshold value and a preset second threshold value; and sending out a first prompt or a second prompt according to the comparison result. Closed-loop control over the blood flow speed is achieved, and a user can be warned of the possible deep vein thrombosis risk.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a system for preventing deep vein thrombosis of lower extremities and a method for using the same. Background technique [0002] Deep vein thrombosis of the lower extremity is a critical illness, and its morbidity remains high in the surgical ward. Causes of stasis of blood flow include: bedridden for a long time, trauma or fracture, major surgery, pregnancy, childbirth, sedentary long-distance travel or airplane, or prolonged sitting and squatting position, etc. All of the above reasons can lead to slow blood flow and stasis, thus promoting the formation of deep vein thrombosis in the lower extremities. After the fracture of the lower extremity, the plaster or other immobilization methods immobilize the affected limb, limit the movement, the muscles of the calf cannot function normally, the blood flow is slow and stasis, so the incidence of deep vein thrombosis of the l...

Problems solved by technology

[0003] However, the venous thromboembolism prevention method in the prior art is to electrically stimulate the body parts of the patient through electrodes to cause passive muscle contraction to prevent venous thromboembolism, but the problem of the patient cannot be detected in time, resulting in poor treatment effect Not obvious or even delayed treatment
