Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a wearable anti-itching device for patients with uremia and pruritus. Background Art

[0002] Uremia is the late stage of chronic renal failure, specifically patients with chronic kidney disease stage 5. It is not an independent disease, but a common clinical syndrome of various late-stage kidney diseases, and a syndrome composed of a series of clinical manifestations that appear when chronic renal failure enters the terminal stage.

[0003] When chronic kidney disease develops to the uremia stage, patients often face the stubborn symptom of skin itching that affects their quality of life. The skin itching of patients with uremia is mainly the result of the combined effects of multiple factors such as toxin accumulation, electrolyte imbalance and dry skin. For the skin itching of patients with uremia, continuous anti-itching operations are required to relieve the discomfort of patients. The current anti-itching operations usually include: 1. The patient scratches with his palms and fingers; 2. Use auxiliary structures such as scratchers to perform anti-itching operations; 3. Nursing operations such as scratching by nursing staff; regardless of the various operations, the following problems usually exist to varying degrees: 1. It consumes the physical strength, energy and time of the patient or the nursing staff, making the anti-itching effect inefficient; 2. The duration is short and the patient's discomfort cannot be relieved in time; the patient's back cannot be de-itched in time and effectively; the existing anti-itching devices are usually simple handheld scratchers or large massage equipment, which are less economical and applicable, and the anti-itching or massage forms are single, resulting in poor anti-itching effects;

[0004] Therefore, based on the above-mentioned deficiencies, there is a need to provide a wearable anti-itching device for patients with uremia and pruritus, which can quickly, effectively and stably remove itching on the back of uremia patients. Summary of the invention
