Abstract: A skin treatment device and a method to cleanse and balance pH value of skin. The skin treatment device includes a nozzle to be directed into contact with the skin of a subject. A vacuum pump may be operably coupled to the nozzle for generating a suction force of the nozzle to evacuate impurities from the skin. A liquid replenishing assembly may be operably coupled to the nozzle for atomizing liquid at a pre-defined pH value. The liquid from the liquid replenishing assembly may pass into the nozzle based on the pre-defined pH value. The first control valve may be connected to an outlet of the vacuum pump and an outlet of the liquid replenishing assembly for communication with the nozzle.

Abstract: An intestinal barrier sleeve release system includes a tubular housing having a first opening at one end and a second opening at the other end. A tubular sleeve to be released is disposed in the housing. A release body connected to the one end of the tubular sleeve is disposed at the first opening of the housing and is made of a material that can be dissolved and absorbed in human intestines. An inner sheath, a middle sheath and an outer sheath are sequentially set and move relative to each other. The inner sheath and the middle sheath are operated to move axially, the release body is disengaged from the housing, and the tubular sleeve moves out of the housing and is released at a specified position of the human intestines.

Abstract: A drainable ostomy pouch outlet includes a single-piece closure member including at least one transversely-extending fold-line. The at least one transversely-extending fold-lines are configured to facilitate folding up and closing of the outlet. The single-piece closure member may also include at least one axially-extending or slanted fold-lines intersecting the at least one transversely-extending fold-line, configured to facilitate opening of the outlet.
