Title:
ADSORPTION APPARATUS AND NEGATIVE PRESSURE TREATMENT HEAD
Document Type and Number:
WIPO Patent Application WO/2022/083661
Kind Code:
A1
Abstract:
An adsorption apparatus and a negative pressure treatment head. The adsorption apparatus comprises an adsorption body (100) and an edge turning structure (200); the adsorption body (100) comprises an adsorption cavity (110); the adsorption cavity (110) is opened towards a first direction; the edge turning structure (200) is connected to the adsorption body (100) and is located at the open end of the adsorption cavity (110); and the edge turning structure (200) extends along a second direction forming an angle with the first direction, so that the edge turning structure (200) can alleviate the feeling of pain of a region (10) to be treated, and improves the adsorption stability of the adsorption apparatus.
