Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a skin moisture state detection device. Background Art

[0002] At present, PICC is widely used in the clinical treatment of cancer patients. However, since patients need to have catheters in place for a long time, the degree of drying during PICC dressing changes is affected by factors such as waiting time, temperature, and air humidity. It is difficult for medical staff to accurately judge and control the degree of drying. As a result, the patient's skin is covered with sterile dressings without being fully dried after local disinfection, which in turn causes some patients to develop moisture-related dermatitis. Moisture-related dermatitis refers to skin inflammation or erosion caused by long-term exposure of the skin to a humid environment. This phenomenon not only causes discomfort and pain to patients, but may even cause skin infection at the PICC catheter site. In addition, severe cases may also lead to unplanned catheter removal, thereby increasing the cost of catheter maintenance and affecting the patient's normal treatment and recovery.

[0003] Therefore, in view of the lack of a device for detecting the moisture status of the local skin during the existing clinical PICC dressing change process, a skin moisture status detection device needs to be designed. Summary of the invention
