Description

Technical Field

[0001] The present invention relates to the technical field of diabetic foot monitoring and rehabilitation, and particularly to a diabetic shoe system for monitoring plantar pressure and decompression of diabetic patients. Background Art

[0002] Diabetic foot is one of the serious chronic complications of diabetes, characterized by high incidence, high disability / mortality rate and high cost. The annual incidence of diabetic foot is about 2%, and the possible incidence rate in a lifetime is as high as 15% - 25%. Increased plantar pressure is an important pathogenic factor for diabetic foot ulcers (especially neuropathic ulcers). Most of the plantar ulcers stem from the repeated increase in plantar pressure. Similarly, pressure shoes and pressure bandages can also cause non-plantar ulcers. However, there is still controversy about the plantar pressure threshold that causes diabetic foot ulcers. Effective decompression of the ulcer site is an important part of the treatment of ulcers (especially neuropathic ulcers). At present, patients must wear specific treatment shoes with decompression insoles to prevent the occurrence of ulcers. However, most of the current treatment shoes are mainly customized insoles and customized treatment shoes. Such customized insoles and customized treatment shoes do not have good decompression ability, and the treatment effect will also show a downward trend when the walking posture of the patient changes later. Summary of the Invention

[0003] In view of the deficiencies that the current plantar pressure monitoring devices for diabetic patients in the above background art do not have decompression ability and do not have the function of distributing plantar pressure, a technical solution for a diabetic shoe system for monitoring plantar pressure and decompression of diabetic patients is provided.

[0004] It includes a monitoring shoe, on the inner upper surface of which a plantar pressure monitoring mechanism is laid, on the upper surface of which a plantar pressure distribution and decompression mechanism is arranged, and above which a banding mechanism is arranged; The monitoring shoe includes a sole, a shoe upper sewn around the upper surface of the sole, and a layer of silica gel cushion layer fixedly connected to the inner cavity surface of the sole by an adhesive; The plantar pressure distribution and decompression mechanism includes a sponge insole, an 11 - 15 row array type airbag mechanism linearly and arrayedly embedded in the sponge insole, and a servo air pump arranged above the plantar pressure distribution and decompression mechanism. The exhaust port of the servo air pump is connected with a main air pipe, and 11 - 15 manifolds communicating with the array type airbag mechanism are branched and penetrated on the side wall of the main air pipe; Specifically, after the servo air pump inflates through the main air pipe, the manifolds and the connecting hoses, the cylindrical airbags will start to expand and push upward, and by controlling the expansion degree of the cylindrical airbags in different areas, the sole of the foot can be lifted, so that the center originally applied to the sole of the foot is transferred to the heel part, and the occurrence of foot ulcers is avoided by distributing the plantar pressure.

[0005] Each of the array - type airbag mechanisms includes 3 - 5 cylindrical airbags arranged horizontally at equal distances, several rigid tubes connected between the adjacent cylindrical airbags, and connecting hoses that penetrate the internal space of the cylindrical airbags and are connected to the manifold. The plantar pressure monitoring mechanism includes 11 - 15 flexible pressure sensors arranged in a linear array, and several wires fixedly connected between the flexible pressure sensors. The total end of the wires is connected to a pressure data transmission line, and a controller is provided at the end of the pressure data transmission line. Specifically, the plantar pressure monitoring mechanism is laid and fixed on the upper surface of the silica gel cushion layer, and the plantar pressure distribution and decompression mechanism is covered on the plantar pressure monitoring mechanism. When the patient walks, the sole and heel of the foot come into contact with the flexible pressure sensors, and the monitored plantar pressure is transmitted to the controller through the flexible pressure sensors. At this time, the controller judges the pressure values of the flexible pressure sensors in each area. When the pressure in the sole area is too high, the controller will control the servo air pump to start working, and at the same time, the electric control valve between the main air pipe and the front - half manifold is opened.

[0006] The banding mechanism includes a canvas tie - strap, a binding strap fixed to the left section of the canvas tie - strap, and a rubber inner lining adhesively fixed to the inner surface of the canvas tie - strap, and the canvas tie - strap and the binding strap are bound around the calf.

The bottom surface of the cylindrical airbag is in contact with the upper surface of the flexible pressure sensor, which is used to detect the force on each area of the sole. The internal spaces of the cylindrical airbag, rigid tubes, and connecting hoses are interconnected.

[0010] In the above technical solution of the diabetic shoe system for plantar pressure monitoring and decompression of diabetic patients, preferably: the top surfaces of the cylindrical airbags all protrude from the inside of the round holes, and the top end faces of the cylindrical airbags are all chamfered in an arc shape.

[0011] In the above technical solution of the diabetic shoe system for plantar pressure monitoring and decompression of diabetic patients, preferably: a front fixing block is fixedly connected to the front surface of the canvas strap, a side fixing block is fixedly connected to the right surface of the canvas strap, a magic mother sticker is fixed to the rear section of the outer surface of the canvas strap, and a magic son sticker is fixed to the inner surface of the binding strap.

[0012] In the above technical solution of the diabetic shoe system for plantar pressure monitoring and decompression of diabetic patients, preferably: the outer shell of the servo air pump is fixed to the outer surface of the front fixing block by glue.

[0013] In the above technical solution of the diabetic shoe system for plantar pressure monitoring and decompression of diabetic patients, preferably: the outer shell of the controller is fixed to the outer surface of the side fixing block by glue.

[0014] In the above technical solution of the diabetic shoe system for plantar pressure monitoring and decompression of diabetic patients, preferably: electric control valves are installed at the connection positions between the main air pipe and the manifold, and the connection hose and the manifold are both connected through pipe joints.

While monitoring the plantar compression force, the forward or backward inclination or horizontal state of the sole is controlled by the different inflation degrees of multiple airbag groups, and the plantar center of gravity is transferred to prevent the forefoot of the diabetic foot from being overloaded and causing ulcers.
