Description

Technical Field

[0001] The present invention relates to the technical field of dandruff sampling devices, in particular to a dandruff sampling device for dermatology testing. Background Art

[0002] The production of dandruff in the human body is mainly due to the metabolism and physiological characteristics of the skin. At the same time, the external environment and living habits will also affect the amount and state of dandruff. The appearance of dandruff is actually part of the skin's self-renewal and protection mechanism. It is a natural result of skin cell metabolism. Some skin diseases, such as seborrheic dermatitis and psoriasis, will lead to increased dandruff or abnormal scales. It is precisely because dandruff can provide direct clues to the health of the skin. In order to quickly and accurately understand the state of human skin, a dermatological dandruff sampling device is needed for detection and analysis.

[0003] Existing dandruff sampling devices generally use a scraper to scrape off the dandruff on the skin surface, and then collect the scraped dandruff in a unified manner. When using a scraper to scrape off dandruff, although it is possible to prevent damage to the patient's skin by controlling the scraper's cutting depth, it is difficult to accurately control the scraper's inclination angle and the force of contact with the skin during scraping, which will make the quality of the dandruff sample unstable and cause the dandruff to fly around and be difficult to collect. Therefore, we propose a dermatological dandruff sampling device for detection. Summary of the Invention
