Problems solved by technology

However, the pressure sensor of the current wireless gait detection device is placed under the patient's foot, and the signal processing and transmission device is placed on the upper of the shoe. It is necessary to connect the sensor to the signal processing and transmission device through an interface, which increases the contact failure between the signal and the processing device. The emergence also brings troubles to patients wearing
And because the pressure sensor is placed under the patient's affected foot, when the affected foot is in contact with the ground, it often falls to the ground, so the signal of the pressure sensor will have an error with the actual gait

Embodiment 1

[0024] An embodiment of a foot drop corrector gait detection device, see figure 1 , there is an insole 1, and a circuit module is arranged in the insole; the circuit module includes a flexible circuit board 2, on which a sensor 3, a microprocessor 4, a wireless communication circuit 5 and a battery 6 are distributed and installed. A circuit protection board 7 is arranged under the flexible circuit board, and the protection board is adhered to the bottom side of the flexible circuit board or the insole. The flexible circuit board is a mature technology, which is a flexible copper clad laminate covered with copper foil on both sides of a 0.1mm to 0.3mm epoxy glass cloth board, and the two sides of the flexible copper clad laminate are corroded by corrosion technology. The outgoing line forms a flexible circuit board; the sensor is directly connected to the microprocessor and wireless communication circuit through the circuit on the circuit board.

[0025] In this embodiment, th...

Embodiment 2

[0027] Another embodiment of a gait detection device for a foot drop corrector, see figure 2 And Example 1, the insole is an injection molding insole, and the difference from Example 1 is that the circuit module and the insole are an open structure for the convenience of assembly, and a circuit module positioning with the same shape as the circuit module is provided on the front or back of the injection molding insole. grooves for placing circuit modules.

Embodiment 3

[0029] Another embodiment of a gait detection device for a foot drop corrector, see image 3 And Embodiment 1, the difference from Embodiment 1 is that the insole is a multi-layer insole, and the multi-layer insole includes an insole surface layer 8 in contact with the sole of the patient's foot and a bottom layer 9 in contact with the insole of the shoe, wherein , a circuit layer is arranged between the surface layer and the bottom layer of the insole, the circuit layer includes an injection molding board 10 and the flexible circuit board 2, the flexible circuit board is installed in the injection molding board, and the flexible circuit board faces the surface of the bottom layer of the insole For the lower layer, the microprocessor, the wireless communication circuit chip and the battery are installed on the lower layer of the flexible circuit board, the sensor is installed on the upper layer of the flexible circuit board, and the mounting surface of the flexible circuit boar...

Abstract

The invention relates to a gait detection device of a foot drop corrector. The device is provided with an insole and is characterized in that the insole is provided with a circuit module; the circuit module comprises a flexible circuit board and a circuit protection board; and sensors, a microprocessor, a wireless communication circuit and a battery are distributed and installed on the flexible circuit board. Compared with the prior art, the device has the following beneficial effects: the device has reasonable structure, realizes direct connection between the microprocessor and the wireless communication circuit as well as the sensors and overcomes the defect of generation of the signals and the contact fault of the treatment device; the integral structure brings convenience for the patients; and the defect that errors between the signals of the pressure sensors and the actual gait are generated because the sick foots always fall to the ground unstably when contacting the ground can be overcome by using the flexible steel board as the circuit protection board.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a gait detection device for a foot drop corrector. The device is used to detect the gait and transmits the output to an electric stimulation device for a foot drop corrector. Background technique [0002] Stroke, traumatic brain injury, spinal cord injury, and multiple sclerosis and other central nervous system diseases often cause foot drop. The patient showed that he could not dorsiflex the foot, and when walking, he either dragged the diseased foot or lifted the lower limb of the diseased side higher, so the gait was slow, abnormal, poor in stability, and unable to walk for a long time. This abnormal gait further causes hip, back, and knee joint injuries, seriously affecting the patient's daily life. [0003] The traditional treatment for foot drop is to use a mechanical foot support to fix the foot and lower leg at a vertical angle, mechanically preventing the fo...
