Technical Field
[0001] This invention relates to the field of nursing device technology, specifically to a foot care device for patients with diabetic nephropathy in the nephrology department. Background Technology
[0002] Patients with diabetic nephropathy in the nephrology department suffer from microvascular complications and neurological dysfunction due to long-term hyperglycemia, making their feet a vulnerable area. Diabetic nephropathy is often accompanied by decreased kidney function, leading to weakened immunity and impaired wound healing. Minor foot injuries can quickly develop into serious infections or ulcers, or even gangrene, increasing the risk of amputation. In addition, nephropathy patients often need to restrict their activities, further deteriorating blood circulation in their feet, making them susceptible to bacterial growth if not properly cared for. Therefore, systematic foot care is crucial, not only preventing foot complications but also reducing hospital infection rates and improving patients' quality of life. Regular cleaning, disinfection, and drying can effectively reduce the probability of skin damage and infection in the feet. Especially for nephrology patients, professional nursing devices can compensate for the shortcomings of manual care, ensuring safe and gentle operation. Existing technologies for foot care have significant shortcomings: traditional methods rely heavily on manual soaking and wiping, lacking automated control and making it difficult to ensure stable water temperature; common devices such as simple foot baths often fail to achieve comprehensive disinfection and precise cleaning of the patient's soles, and the disinfection range is limited, with inaccurate temperature monitoring, easily leading to burns or incomplete cleaning; furthermore, most existing devices do not integrate drying functions, and residual moisture on the feet after treatment may breed bacteria; the operation process requires patients to frequently bend over, increasing discomfort; these shortcomings are particularly prominent for patients with diabetic nephropathy, as their skin is highly sensitive and requires a gentler and more comprehensive care process. Therefore, we propose a foot care device for patients with diabetic nephropathy in the nephrology department. Summary of the Invention

[0021] The working principle of the foot care device for diabetic nephropathy patients provided by this invention is as follows: First, water for cleaning is injected. After injection, all the second heating tubes 10 are activated to heat the water. During the heating process, the second temperature sensor 11 continuously detects the water temperature. When the water temperature reaches the required temperature, the second heating tubes 10 are turned off. Then, the patient's feet are securely placed on the two supporting rubber meshes 22 of the support plate 21. The supporting rubber meshes 22 provide comfortable support through their elastic structure. During the support process, the patient's feet can be soaked. During the soaking process, the moving component 4 is driven by the second motor 54 of the rotating component 5, which synchronously drives the threaded rod 43 to rotate through the sprocket 51 and chain 52, pushing the moving frame 41 to move smoothly back and forth along the limit rod 44. The pressure sensor 45 feeds back the position data to the PLC controller 16 in real time to ensure that the foot cleaning component 6 covers the entire foot area. At the same time, the third motor 71 of the rotating component 7 is activated. The bevel gear 72 meshes with the bevel gear ring 73, driving the connecting shaft 63 to rotate. The worm gear 64 and the worm wheel ring 62 drive the brush bristles 66 on the turntable 65 to rotate gently, effectively removing dirt and dead skin. After the dead skin and dirt on the soles of the feet are removed, the hydraulic rod 24 is activated, causing the connecting frame 23 to move upward and adjust the height of the support plate 21. After adjustment, the patient's feet are moved away from the soaking solution. Then, the suction pump 83 is activated. After the suction pump 83 is activated, the disinfectant is pumped into the U-shaped tube 25 through the injection hose 82. The disinfection component 3 drives the gear 33 and the gear ring 34 to mesh precisely through the first motor 31, driving the connecting barrel 35 to rotate at a uniform speed, so that the atomizing nozzle 36 sprays the disinfectant in all directions, achieving disinfection of the feet without dead angles. After disinfection, all the first electric heating tubes 93 are activated to generate a warm airflow to spray onto the patient's feet, thus drying the patient's feet. After drying, the care is completed. Then, the wastewater is automatically discharged under the control of the PLC through the drain pipe 12 and the solenoid valve 13.
