[0002] With the continuous improvement of medical standards, timely and effective wound cleaning and disinfection are of great significance for preventing infection and promoting wound healing. Traditional wound care relies on manual operations, with caregivers using handheld spray bottles or manual tools to flush and disinfect wounds. This method is not only cumbersome and inefficient, but also carries the risk of uneven operation and secondary contamination of the wound. In addition, manual operation requires a high level of technical skills and experience from caregivers, making it difficult to standardize and automate the process.

[0003] In recent years, with the continuous development of medical equipment, a number of mechanized and automated wound cleaning and disinfection devices have emerged. For example, some devices use robotic arms or mechanical guides to clean the wound area. However, most of these devices are fixed structures and lack flexible adjustment capabilities.

[0029] See also Figure 1-9A wound cleaning device includes a platform 1, which is an integral support platform with a top trough 11 and drainage holes 12 for collecting and discharging cleaning and disinfectant solutions. A waste liquid tank 7 at the rear is connected to the drainage system to ensure timely discharge of waste liquid, maintaining a clean and tidy work area.

[0030] The vertical mounting frame 2 is vertically arranged in front of the top of the platform 1, and a lifting-rotation adjustment component 3 is installed inside it, which can realize the lifting and rotation adjustment of the cleaning component 4, thereby realizing the cleaning operation of the patient's legs or arms. The rotatable design also enables the cleaning component 4 to rotate to any angle so that it can be parallel to the patient's arm, which is more humane and does not require the patient to adjust the arm position.

[0031] The lift-rotation adjustment assembly 3 consists of a first reduction motor 31, a first drive screw 32, a first screw sleeve 33, a rotation motor 34, and a connecting shaft 35. The first reduction motor 31 rotates the screw 32, which in turn moves the screw sleeve 33 axially, thereby raising and lowering the cleaning assembly 4. The rotation motor 34 rotates the screw 32 via the connecting shaft 35, causing the cleaning assembly 4 to deflect, making it more suitable for cleaning the patient's arm.

[0032] The cleaning assembly 4 consists of a vertical connecting frame 41, end connectors 42, a cleaning assembly 43, a disinfection assembly 44, a side connecting frame 45, a positioning assembly 46, and a guide assembly 47. The end connectors 42 are located at the upper and lower ends of the vertical connecting frame 41, forming a semicircular ring structure to ensure the stability of the cleaning and disinfection device.
