Title:
WEARABLE DEVICE FOR ALLEVIATING LOWER LIMB ISCHEMIA, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/016501
Kind Code:
A1
Abstract:
Disclosed in the present invention are a wearable device for alleviating lower limb ischemia, and a control method therefor. The device comprises a main control unit, an electrocardiosignal monitoring unit, a first electrical pulse assembly and a second electrical pulse assembly, wherein the first electrical pulse assembly and the second electrical pulse assembly are each composed of an intermediate-frequency pulse stimulation electrode having a pulse frequency ranging from 1 Kz to 100 Kz and a low-frequency pulse stimulation electrode having a pulse frequency ranging from 50 Hz to 300 Hz. The wearable device is a non-invasive, low-risk, miniaturized, portable and low-cost device that is connected by means of wireless communication, and the wearable device does not need to be operated by professional medical staff, and can prevent risks such as skin damage caused by the effect of a high voltage. In the control method for the wearable device, a control algorithm is set on the basis of an electrocardiosignal, such that a first pulse assembly and a second pulse assembly output electronic pulses at specific modulation waves and according to a preset instruction, so as to generate a hammering effect, thereby achieving the effects of improving the hemodynamic environment of lower limbs and effectively improving the blood flow velocity at the lower limbs. The control method is simple to operate and has high accuracy.
