Foot drop self-adaptive stimulator

Abstract

The invention discloses a foot drop self-adaptive stimulator, which comprises a left and right stimulation electrode selection switch, a buzzer, a press key, an internal circuit and the like, wherein the internal circuit comprises a single chip, a variable voltage high-voltage generating circuit, a variable constant-current control circuit and a double-shaft angle sensor, the press key circuit can manually regulate the intensity of stimulation current and can also stop or restart the output, the variable voltage high-voltage generating circuit regulates the intensity of the output stimulationvoltage according to the concrete requirements of patients, and the constant-current control circuit can precisely generate the simulation current, the double-shaft angle sensor can precisely measurean included angle between the crus of the patients and the sagittal axis, and can transfer the value of the included angle to the single chip for carrying out processing and judgment to obtain the precise position and occasion to start the stimulation on the patients. The invention has the advantages of simple installation, convenient operation and adjustable stimulation intensity, is applicable to people with normal legs and feet and the patients with abnormal legs and feet, can automatically adapt to the walking rhythm of the patients, can select the left foot and the right foot, has the falling warning function and the like, and is suitable for various foot drop patients to use.

Description

technical field [0001] The invention belongs to an auxiliary device for human body rehabilitation, and is suitable for foot drop caused by cerebral apoplexy and other causes out of control of the common peroneal nerve. It involves the detection of the calf posture of the patient when walking, and timely release of electrical stimulation pulses when walking needs to lift the foot to force the patient to automatically lift the foot to complete the walking action, and automatically continue to stimulate the patient in a certain period according to the movement speed before the patient steps out of the calf to maintain Lift your feet. Background technique [0002] At present, many patients will lose control of the common peroneal nerve after mild stroke or other reasons, and then cause foot drop. These patients have a certain ability to take care of themselves, but because they cannot lift their toes independently during walking, they may fall and cause unnecessary injuries, an...
