Abstract
A reduced-pressure device for wound treatment includes a housing, an air pressure storage unit, a compression unit and a pressure indicating module. The air pressure storage unit is installed in the housing and comprises a pressure storage container, a piston assembly and a piston spring, and the compression unit is mounted on the piston assembly, and the pressure indicating module is engaged to the pressure storage container and the piston assembly. Therefore, the user can see the information shown on the pressure indicating module to be easily aware of how much capacity of negative pressure the reduced-pressure device can continuously be provided in order to determine when to operate the compression unit again for providing the desired negative pressure.
