Abstract

The invention relates to a portable negative pressure device. The portable negative pressure device comprises a casing, a piston, a blocking ball and a spring mechanism, so that a first liquid storage area and a second liquid storage area which can be compressed to form a negative pressure source can be formed. Under the condition that exudation is stored in the first liquid storage area, sufficient negative pressure of the portable negative pressure device can be maintained by continuously compressing the piston, and additional liquid storage space can be provided by the second liquid storage area.

Description

Technical field [0001] The invention relates to a portable negative pressure device used for a negative pressure dressing, in particular to a portable negative pressure device that is convenient for manually generating a negative pressure source. Background technique [0002] The natural healing of body wounds is a complex process that starts at the time of injury. First, the body minimizes damage by directing blood to the wound to deliver proteins and other clotting substances. Blood clots are used to prevent blood loss, while the cells swallow bacteria and debris from the wound. Next, in the healing phase called the proliferation phase, the body begins to repair itself and granulation tissue is deposited on the wound surface. Granulation tissue provides the basic structure on the wound, and cells can migrate from the periphery of the wound to the inside to close the wound. Finally, over time to form scars. [0003] In the prior art, the wound dressing only uses physical adsor...
