Detailed Embodiment

[0017] The present utility model will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0018] Embodiment: An airbag support shoe for diabetic toe amputation patients includes a shoe upper 1 and a sole 2, as shown in the attached Figure 1As shown, the upper surface of the sole 2 has a plurality of air bags 3 corresponding to the toes, as shown in the appendix Figure 2 As shown, there are a total of five air bags corresponding to five toes. One end of the plurality of air bags 3 is connected to a tap 4 via a trachea. The tap 4 is fixed on the upper 5. The air inlet end of the tap 4 is provided with an air valve 6. The air valve is a conventional air pressure valve for controlling the on and off of gas. The specific structure will not be elaborated here; the five air bags correspond to five tracheas. The five tracheas are connected to the tap. Each air valve controls the inflation and deflation of a single air bag. In order to prevent the multiple conduits from being randomly raised, the multiple conduits are fixed by being sleeved with a sleeve. In this embodiment, the air bags can be arranged by providing multiple small air bags at each toe. Since the toe defects vary in length, some are only partially defective, and it is also possible that multiple toes are defective. Each defective toe may also vary in length. For the defective part, the corresponding small air bag is inflated. In addition to the toe part, there are also multiple air bags in other parts from the front foot to the midfoot. Because there may be amputations of the front foot or midfoot, the lengths of the stumps may vary, the defects on the inner and outer sides of the foot may vary, and they may even be irregular. There are multiple air bags in the above-mentioned parts. The number of inflated air bags and the pressure can accurately fill the defects; secondly, the plantar pressures of diabetic foot patients are inconsistent, and there are also multiple air bags in other parts of the sole. The selective inflation of air bags and the pressure can meet different plantar pressure requirements, preventing and reducing the recurrence of diabetic foot; finally, a computer electronic sensor is additionally equipped for gait measurement and plantar pressure measurement to guide shoe making and air bag inflation; the air outlet end of the tap 4 is connected to a delivery pipe 7, and the end of the delivery pipe 7 is connected to a valve nozzle 8 for easy inflation, as shown in the appendix Figure 4 As shown. The front end of the sole 2 has a plurality of connectors 12 with one-way valves. The connectors 12 are connected to the air bags 3. Each connector corresponds to each air bag. The tap 4 is connected to the connector 12 via a trachea. The end of the trachea is connected to the connector by a snap structure. After snapping, the one-way valve inside the connector can be opened to realize the internal communication between the trachea and the air bag. Considering the actual use and comfort of patients, after the air bag is inflated, the trachea is separated from the connector, and the internal one-way valve is closed. The trachea, tap, and air delivery pipe are all removed from the upper. The valve nozzle 8 includes a valve nozzle body 81. The valve nozzle body 81 has a positioning ring 82 inside. A closing body 83 is installed in the valve nozzle body 81. The end of the closing body 83 has a sealing outer inclined surface 84. The inner side of the end of the valve nozzle body 81 has a sealing inner inclined surface 85 that fits with the sealing outer inclined surface 84; the other end of the closing body 83 is sleeved with a spring 86. One end of the spring 86 abuts against the positioning ring 82. In the normal state, the sealing inner and outer inclined surfaces are mutually attached to ensure the sealing inside the entire pipeline. During inflation, the closing body is pushed open and the gas passes through the pipeline. The inner end of the closing body 83 has a side branch 87. The spring 86 is sleeved on the side branch 87, and one end of the spring 86 abuts against the stepped opening on the side branch 87. Through this structure, the spring can be stably placed.

[0019] One end of the tap 4 is provided with a fixing piece 9, and the fixing piece 9 has a fixing hole 10; fixing straps 11 are symmetrically installed on the upper surface 1 of the shoe, and one side of the fixing strap 11 passes through the fixing hole 10, as shown in the appendix Figure 3 shown, and one end of the fixing strap 11 is connected to the upper surface 1 of the shoe by Velcro; the other side of the fixing strap 11 buckles the other end of the tap 4, and the fixing strap is sewn on the inclined surface, and the fixing straps on both sides can fix the tap

[0020] The working principle of the present utility model: according to the position of the amputated toe of the patient, the air valve of the corresponding trachea on the tap is opened, and air is inflated into the delivery tube through the valve nozzle. The gas enters the corresponding catheter through the guidance of the tap, and finally is inflated into the corresponding airbag. The airbag begins to expand and occupies the space of the missing toe, helping the patient to walk stably and improving the convenience and comfort of walking
