DETAILED DESCRIPTION

[0023] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0024] like Figures 1 to 6 As shown, the diabetic foot shoe of this embodiment includes a sole 100 and an upper 200 for covering the foot. The sole 100 includes a wear-resistant layer 110 located at the bottom, a circuit layer 120 arranged on the wear-resistant layer 110, and an insole 130 laid on the circuit layer 120, and a circuit board 121 is arranged in the circuit layer 120. The upper 200 includes a waterproof layer 210 arranged at the outermost side, a wiring layer 220 arranged on the inner side of the waterproof layer 210, and an electric heating layer 230 arranged on the inner side of the wiring layer 220, and the electric heating layer 230 is mainly composed of a flexible electric heating film 231. A removable footwear 300 is provided in the cavity surrounded by the upper 200 and the sole 100, and a removable electrical stimulation belt 400 is provided in the footwear 300. The electrical stimulation belt 400 includes a fixing belt 410 that can be connected end to end to form a circle, and a stimulation electrode 420 arranged on the inner side of the fixing belt 410. The stimulation electrode 420 and the flexible electric heating film 231 are connected to the circuit board 121 through a wire 500 that passes through the wiring layer 220. The circuit board 121 is used to control the stimulation electrode 420 to perform electrical stimulation and control the flexible electric heating film 231 to generate heat.

[0025] It can be understood that a flexible electrothermal film, also known as a flexible heating film, is a thin film material that can achieve a plastic structure and high-efficiency heating function. It is generally formed by combining conductive materials and polymers with high-temperature stability, usually in a thin film or a combination of thin films. When an electric current is applied to this material, heat energy is generated and transferred to nearby objects or spaces. Therefore, the flexible heating film can quickly and evenly heat the target area to meet various heating requirements. Common ones include PET electrothermal films, FPC electrothermal films, and silicone electrothermal films. Electrical stimulation mainly includes muscle electrical stimulation (EMS) and functional electrical stimulation (FES). However, the functions of both are generally to use low-frequency pulsed current to stimulate muscles to make them contract. The former is mainly to activate and exercise motor muscle fibers, and the latter is mainly to compensate for damaged muscle tissues. Through the action of electrical stimulation, the function of damaged tissues can be compensated, and electrical stimulation can be used to exercise the foot muscles of patients and promote recovery. Since the heating method of the flexible electrothermal film and the electrical stimulation method of the stimulating electrode are both conventional techniques in this field, and the circuit for controlling its operation is also an existing technology in this field, the specific circuit is not described in detail in this application, and only the spatial layout and connection of various specific components are involved.

[0026] The circuit layer 120 includes several support plates 124 fixed on the wear-resistant layer 110, a metal mesh 122 laid flat on the top of the support plate 124, and a side edge 123. The side edge 123 is arranged at the top edge of the wear-resistant layer 110 and surrounds the support plate 124 and the metal mesh 122. The circuit board 121 is arranged in the gap between several support plates 124, and the metal mesh 122 is provided with mesh holes through which the wire 500 can pass. The materials of the wear-resistant layer 110, the waterproof layer 210, and the side edge 123 can all be selected as rubber, which can have characteristics such as wear resistance and waterproofness at the same time. In this embodiment, by setting two support structures, namely the support plate 124 and the metal mesh 122, in the circuit layer 120, the sole is ensured to have sufficient support strength to prevent the circuit structure inside the sole from being damaged when the patient wears shoes. At the same time, this structural arrangement can leave enough space in the sole for placing the circuit board and arranging the circuit, and is also conducive to pulling the wire upward without interfering with the use of the stimulating electrode 420 and the flexible electrothermal film 231. The metal mesh 122 can be made of metal or alloy with rust prevention function and certain strength, such as stainless steel or titanium alloy, etc. To facilitate wiring, a certain gap can be left at the edge of the insole 130 and the inner side of the shoe upper 200, or some through holes can be opened in the insole 130. The material of the insole 130 can refer to common insoles, which can be cotton, or EVA, PU, memory foam, or latex, etc.

[0027] The wiring layer 220 includes a heat insulation sheet 221 made of heat insulation material and several vertical bars 222 arranged on the outer side of the heat insulation sheet 221. A wiring groove 223 capable of passing a wire 500 is formed between two adjacent vertical bars 222, the heat insulation sheet 221 and the waterproof layer 210. The electric heating layer 230 is composed of flexible electric heating films 231 distributed alternately and connecting pieces 232 connected between adjacent flexible electric heating films 231. A hole 233 is formed in the connecting piece 232, and a wiring hole 224 is formed in the heat insulation sheet 221 at the bottom of the hole 233. The wire 500 connecting the flexible electric heating films 231 passes through the hole 233 and the wiring hole 224 and then enters the wiring groove 223. Among them, the heat insulation sheet 221 can be some common polymer materials with certain heat insulation functions, such as artificial leather, aerogel materials, etc. The connecting piece 232 can be selected as a flexible material, and some common rubber and plastic materials can be used, such as rubber, mainly to connect two adjacent flexible electric heating films 231 and make holes without damaging the flexible electric heating films 231. After the flexible electric heating film 231 controls heat release through the circuit board 121, it can heat and keep warm the patient's foot, and has the effects of promoting blood circulation and improving comfort.

[0028] The fixing band 410 is an elastic band, and its two ends are connected by a magic tape, so as to fix the fixing band 410 at the required part of the foot. The material of the shoes and socks 300 is a textile fiber capable of absorbing water, such as cotton or a mixed textile fiber containing cotton, which helps to absorb moisture from the patient's foot. In particular, the shoes and socks 300 can be taken out, which is also convenient for cleaning and replacement. When in use, first select a suitable position according to the patient's foot condition and put on the electrostimulation band 400. The number of electrostimulation bands 400 can also be increased or decreased according to the actual situation; then put on the dry shoes and socks 300, put the foot together with the shoes and socks 300 into the shoes; finally, perform electrostimulation and / or electroheating according to the needs.

[0029] In addition, the whole diabetic foot shoe is in the shape of a high-boot, and a zipper 700 capable of opening the shoe upper 200 is arranged on the front side of the shoe upper 200. Through the zipper 700, it is convenient to open the shoe and then put the swollen foot into the shoe. A pocket 900 is also arranged on the rear side of the top of the shoe upper 200, and the pocket 900 can be used to place the electrostimulation band 400 that is not needed, the too long wire part and other accessories.

[0030] In addition, a storage battery is installed inside the circuit layer 120 or on the outer side of the shoe upper 200, and the storage battery is used to supply power to the circuit board 121, the flexible electric heating film 231 and the stimulation electrode 420; a charging interface 600 is arranged on the rear side of the shoe upper 200, and the charging interface 600 is used to charge the storage battery. A control panel 800 is arranged on the outer side of the shoe upper 200, and the control panel 800 is electrically connected to the circuit board 121. The control panel 800 can be provided with a display screen for displaying the internal temperature and the electrostimulation intensity, and buttons for adjusting these parameters.

[0031] It should be understood that all of the above embodiments are exemplary rather than restrictive. Under the concept of this application, various modifications or deformations made by those skilled in the art to the specific embodiments described above should fall within the protection scope of this application.
