Description

Technical Field

[0001] This utility model relates to the technology of auxiliary devices for traditional Chinese medicine physiotherapy, and more specifically, it relates to a support for changing dressings on foot wounds. Background Technology

[0002] Diabetes mellitus is a metabolic disease characterized by hyperglycemia caused by insulin secretion defects or insulin action disorders. Sustained hyperglycemia and long-term metabolic disorders can lead to damage and dysfunction of various tissues and organs throughout the body, particularly the eyes, kidneys, cardiovascular system, and nervous system. In severe cases, it can cause acute complications such as dehydration, electrolyte imbalance, and acid-base imbalance, including ketoacidosis and hyperosmolar coma. With increasing age, the incidence of diabetic foot in the elderly rises, with more than 15% developing foot ulcers or gangrene, severely impacting patients' quality of life and placing a heavy burden on society and families. Because diabetic foot differs from ordinary traumatic ulcers—it is a serious disease secondary to diabetic microvascular and neuropathy complicated by infection—wounds heal slowly and require continuous and effective treatment of foot wounds.

[0003] Patients with diabetic foot need to have their foot wounds dressed regularly. Diabetic foot patients are usually older and have limited mobility. Currently, the common method for dressing changes is for the patient to place their legs flat on the bed or extend their feet off the bed and support them with a support bracket, while medical staff clean and dress the affected foot. However, because the height of the support bracket cannot be adjusted, the patient's feet may experience numbness or other discomfort if placed on an unsuitable bracket for a long time. Moreover, dressing changes on the support bracket or the bed can soil the sheets and support bracket, making cleaning very inconvenient. Utility Model Content

A sewage tank 31 connected to the bottom of the liquid receiving tank 11 through a hose is provided below the disinfection water tank 30. Waste liquid in the receiving tank 11 can be discharged into the sewage tank 31 for storage to prevent the odor generated by the waste liquid from drifting into the air; the second lifting drive device can drive the protective cover 28 to descend and block the opening of the receiving tank 11, and then the water pump draws the disinfectant water in the disinfectant tank 30 into the spray pipe 29, and then the nozzle of the spray pipe 29 sprays downward to rinse the airbag 7, the top seat 5, and the foot support 6.

[0035] In this embodiment, multiple infrared light tubes 32 are arranged above the water spray pipe 29 inside the protective cover 28, and a power supply 38 connected to the infrared light tubes 32 via wires is provided on the second lifting seat 27; a transparent glass is provided inside the protective cover 28 between the water spray pipe 29 and the infrared light tubes 32; the infrared light tubes 32 are arranged perpendicularly to the water spray pipe 29. The infrared light tubes 32 arranged inside the protective cover 28 can heat the patient's affected foot, improving the patient's comfort during long-term foot dressing changes in cold seasons; moreover, the infrared light emitted by the infrared light tubes 32 also has a bactericidal effect. After rinsing the airbag 7, top seat 5, and footrest 6, the infrared light tubes 32 can be turned on for drying and sterilization.

[0036] In this embodiment, the second lifting drive device includes a second lead screw 33 rotatably mounted on the other side of the vertical frame 8 via a bearing and a second lead screw nut 34 mounted on the second lifting seat 27. The second lead screw nut 34 is adapted to the second lead screw 33. A second motor 35 is provided inside the vertical frame 8 to drive the second lead screw 33 to rotate. The guide rod 23 is provided with two limiting rings 36 that are respectively adapted to the top surface of the first lifting seat 10 and the bottom surface of the second lifting seat 27. The second motor 35 can drive the second lead screw 33 to rotate, causing the second lifting seat 27 to slide along the guide rod 23, thereby driving the protective cover 28 to rise and fall, adjusting the position of the protective cover 28. At the same time, the second lifting seat 27 is provided with a guide hole adapted to the upper part of the first lead screw.

[0037] In this embodiment, a control panel 37 is provided on one side of the vertical frame 8. The control panel 37 has multiple start / stop buttons and is used for electrical connection of the first motor 26, the second motor 35, the water pump, the micro air pump 17, and the solenoid valve. The operation of the first motor 26, the second motor 35, the water pump, the micro air pump 17, and the solenoid valve can be controlled through the control panel 37.

[0038] Working principle:

[0039] In practical use, the height of the footrest 6 can be adjusted by rotating the cylinder 4 so that the patient's foot can be placed on the footrest 6 in the most comfortable position. The positions of the bottom plate 14, left guard plate 15 and right guard plate 16 can be adjusted to accommodate different sizes of foot. Then, the clamping force can be adjusted by adjusting the air pressure of the airbag 7 to position the patient's foot.

[0040] During the dressing change, the medication will flow into the receiving tank 11 to avoid contaminating the floor. In cold weather, the protective cover 18 can be lowered by the second motor 35, and then the infrared light tube 32 can be turned on to keep the patient's foot warm.

[0041] After the dressing change is completed, the first motor 26 drives the liquid receiving tank 11 to rise, and the second motor 35 drives the protective cover 18 to fall, so that the protective cover 18 seals the opening of the liquid receiving tank 11. Then the water pump is started to draw the disinfectant in the disinfectant tank into the spray pipe 29, so that the nozzle sprays downward to clean the airbag 7, the top seat 5, and the foot support 6. The wastewater flows downward into the liquid receiving tank 11, and then flows into the sewage tank 31 through the hose for sealed storage.

[0042] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
