Description

Technical Field

[0001] The utility model relates to the technical field of skin medicine application, in particular to a skin medicine application device suitable for vitiligo patients. Background Art

[0002] Vitiligo is a common pigmented skin disease, generally characterized by local or generalized loss of pigmentation to form white spots. It can occur in all parts of the body, such as the pigment cells of the eyes and ears. It is a systemic disease that mainly invades skin pigments and can also invade other pigment cells throughout the body. There are many factors that induce vitiligo, such as mental factors, genetics, trauma, frequent contact with chemical substances, endocrine disorders, autoimmune factors, environmental factors, etc. The treatment process of vitiligo requires long-term persistence and it is difficult to be completely cured in a short period of time.

[0003] Common topical liquid medicines for treating vitiligo include compound angelica dahurica tincture, glucocorticoids, Chinese herbal medicines, etc. These liquid medicines are dark in color. If applied to normal skin, they can easily cause pigmentation and affect the color of normal skin. They are also irritating. Therefore, when applying the above liquid medicines, try to avoid applying them to normal skin. However, since the size of vitiligo-affected skin is irregular and the boundary with normal skin is irregularly serrated, the applicator heads of existing skin applicators generally adopt a single-head structure. If the applicator head is too large, it is easy to apply the liquid medicine to normal skin when applying the medicine to some small-sized or bordered diseased skin. If the applicator head is too small, the application speed will be relatively slow when applying the medicine to a large-scale diseased skin. Therefore, it is not applicable. Utility Model Content
