Description

Technical Field

[0001] This utility model relates to a multifunctional wheelchair footrest cover to prevent foot injuries. Background Technology

[0002] The foot is a complex target organ of diabetes, a multi-system disease. Diabetic patients, due to peripheral neuropathy and peripheral vascular disease combined with excessive mechanical pressure, may experience damage and deformities in the soft tissues and musculoskeletal system of the foot, leading to a series of foot problems, from mild neurological symptoms to severe ulcers, infections, vascular diseases, and neuropathic fractures. If aggressive treatment fails to adequately address the symptoms and complications in the lower limbs, it can have disastrous consequences. Therefore, early prevention and treatment of foot problems in diabetic patients is of great significance. An existing type of wheelchair pedal for diabetic patients, such as... Figure 1 As shown, it includes a vertical rod 1, a connector 11 at the top of the vertical rod 1, and a horizontal rod 2 at the bottom of the vertical rod 1 facing forward. A sleeve 3 is provided on the horizontal rod 2 for limiting movement. Limiting blocks 22 and limiting plates 21 are provided on the horizontal rod 2 on both the front and rear sides of the sleeve 3. A pedal 4 is fixedly provided on one side of the sleeve 3. The pedal 4 has several strip-shaped protrusions 41. The pedal 4 can be laterally limited by the sleeve 3 and can be folded vertically (existing technology).

[0003] The foot pedal 4 of the aforementioned diabetic wheelchair is rigid and comes into hard contact with the feet of diabetic patients, which can easily cause pressure damage to the feet of diabetic patients and is not conducive to the rehabilitation treatment of diabetic patients' feet. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional wheelchair footrest cover that prevents foot injuries. This footrest cover avoids hard contact between the feet of diabetic patients and the footrest, thus preventing pressure injuries and effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional wheelchair footrest cover for preventing foot injuries, comprising a detachable cover body on the footrest, the cover body having a rectangular structure, with a first hook and loop fastener base fixed downwards at both the front and rear ends, and a first hook and loop hook that cooperates with the first hook and loop fastener on both the front and rear sides of the footrest; An inflatable airbag is attached to the upper side of the sleeve. The inflatable airbag is flat and rectangular, with an inflation nozzle on the front. A heated foot pad is attached to the upper side of the inflatable airbag; The sleeve body is provided with a fixing sleeve on the left and right sides respectively. The fixing sleeve is rectangular in shape, and its inner end is fixedly connected to the left and right sides of the sleeve body respectively. The outer end of the fixing sleeve is provided with a hook and loop fastener that cooperates with each other.

[0006] As a preferred technical solution, the foot pad is provided with a heating wire, which is connected to the inner end of an external power cord. The outer end of the power cord is provided with a plug, and a control switch is also provided on the power cord.

[0007] As a preferred technical solution, the foot pad and the fixing sleeve have the same structure, both being composite structures, including a bamboo charcoal fiber layer on the lower side, a polyester fiber layer on the upper side of the bamboo charcoal fiber layer, and a silk fiber layer on the upper side of the polyester fiber layer.

[0008] As a preferred technical solution, the length of the first hook and loop fastener is less than the width of the pedal.

[0009] As a preferred technical solution, the front and back width of the fixing sleeve is the same as the front and back width of the foot pad.

[0010] As a preferred technical solution, the left and right widths of the sleeve are the same as the left and right widths of the pedal.

[0011] Compared with the prior art, this utility model provides a multifunctional wheelchair footrest cover to prevent foot injuries, which has the following beneficial effects: 1. This utility model features a detachable sleeve on the pedal. The sleeve has a rectangular structure, with a first hook and loop fastener base fixed downwards at both the front and rear ends. The front and rear sides of the pedal are respectively provided with first hook and loop hooks that cooperate with the first hook and loop fasteners. In use, the sleeve can wrap around the upper side of the pedal through the cooperation of the first hook and loop fastener base and the first hook and loop hook, which can avoid hard contact between the sole of the diabetic patient's foot and the pedal, and play a preliminary protective role.

[0012] 2. This utility model has an inflatable airbag attached to the upper side of the sleeve. The inflatable airbag is flat and rectangular, with an inflation nozzle on the front. In use, the airbag can be inflated or deflated through the inflation nozzle to adjust the thickness of the airbag, thereby facilitating the adjustment of the patient's foot comfort.

[0013] 3. This utility model has a foot pad with heating function attached to the upper side of the inflatable air bag. When in use, the foot pad can heat and keep the feet warm, which helps to improve the comfort of use.

[0014] 4. This utility model has fixed sleeves on the left and right sides of the sleeve body. The fixed sleeves are rectangular in structure, and their inner ends are fixedly connected to the left and right sides of the sleeve body. The outer ends of the fixed sleeves are equipped with hook and loop fasteners that cooperate with each other. When in use, the left and right fixed sleeves can be wrapped around the instep and fixed with hook and loop fasteners. The tightness can be adjusted, which can play a role in assisting to fix and keep the feet warm. Attached Figure Description
