Embodiment 1

[0037] combine figure 1 , a kind of O-shaped leg correcting device that utilizes muscle sound signal detection of the present embodiment comprises fastening belt 1, upper strap 5 and lower strap 6, and the three are ring-shaped, and fastening belt 1 connects ribbon 11 and The upper strap 5 is connected, and the upper strap 5 is connected with the lower strap 6 through the strap connecting band 12 . When worn, the fastening belt 1 is positioned at the waist, the upper strap 5 and the lower strap 6 are positioned at the upper and lower sides of the knee respectively, and the connecting ribbon 11 and the strap connecting strap 12 are elastic belts, which have a certain space for expansion and contraction. Further, a buckle can be provided on the connecting ribbon 11 , and the length of the connecting ribbon 11 can be adjusted through the buckle. The fastening belt 1 can be an integral elastic belt or a buckle-type connection belt that can be connected to each other through other...

Embodiment 2

[0050] A kind of O-shaped leg correction device utilizing muscle sound signal detection in this embodiment has the same basic structure as that of Embodiment 1, the difference being that the connecting ribbon 11 is connected with the fastening belt 1 through the sliding buckle 2, and the sliding buckle 2 It can slide relative to the fastening belt 1, and the position of the sliding buckle 2 can be adjusted within a certain range.

[0051] The upper strap 5 and the lower strap 6 in this embodiment are all made up of a fixed-length strap 7 and a telescopic strap 8, and the lower correction airbag 15 and the muscle sound signal sensor 13 are all arranged on the inner side of the fixed-length strap 7, and the telescopic strap 8 is Elastic fabric straps. Due to the elastic cloth belt, the strap has a certain degree of stretchability, which is suitable for wearing, and the detection electrode and the leg are more tightly fitted to ensure the accuracy of detection.

Abstract

The invention discloses a knee varus orthotic device adopting myocrismus signal detection, and belongs to the field of medical instruments. The knee varus orthotic device comprises a fastening belt, an upper bandage and a lower bandage, wherein the fastening belt is connected with the upper bandage through a connecting silk cord, and the upper bandage is connected with the lower bandage through a bandage connecting band; orthotic airbags are arranged in the upper bandage and the lower bandage, a myocrismus signal sensor is arranged on the inner side face of the lower bandage, an air inlet and outlet motor and a signal processing module are arranged in the fastening belt, and the myocrismus signal sensor is electrically connected with the signal processing module; when the myocrismus signal sensor detects that legs are in the knee varus posture, the orthotic airbags are inflated through the air inlet and outlet motor so as to increase orthotic pressure. By combining the myocrismus detection technique with a wearable device, knee varus correction can be achieved by means of external force, a user can be reminded to stay in a correct posture, the using effect is good, and the treatment cycle of knee varus is shortened.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically relates to an O-shaped leg correction device using muscle sound signal detection. Background technique [0002] O-shaped leg is a deformity disease whose main manifestation is that when the lower limbs are naturally straightened or standing, the inner malleolus of the two feet touch and the knees cannot get close. People with O-shaped legs have varus knees, and their body weight is concentrated on the inner articular surface of the knee joint, causing wear and tear on the inner cartilage surface of the knee joint, which can easily cause arthritis and even joint pain, which affects normal walking. [0003] At present, the correction methods of O-shaped legs include surgical correction and non-surgical correction. Surgical methods are suitable for more serious patients, with quick results but higher risks. Non-surgical correction methods include correction instrument...
