Manually Activated Negative Pressure Therapy System With Integrated Audible Feedback

A manually-actuated pump for providing reduced pressure treatment, the manually-actuated pump comprising:

• a charging chamber configured to be charged with a reduced pressure in response to actuation of the pump;
• a regulated chamber in fluid communication with the charging chamber, the regulated chamber configured to regulate the reduced pressure and provide the reduced pressure to a treatment site;
• and
• a feedback module comprising a pressure sensor in fluid communication with the charging chamber.

A manually-actuated pump for providing reduced pressure treatment, the manually-actuated pump comprising:

• a charging chamber configured to be charged with a reduced pressure in response to actuation of the pump;
• a regulated chamber in fluid communication with the charging chamber, the regulated chamber configured to regulate the reduced pressure and provide the reduced pressure to a treatment site;
• a housing enclosing the charging chamber and the regulated chamber;
• a housing extension coupled to the housing adjacent to the charging chamber;
• a cover arranged over the housing extension, wherein the cover and the housing extension define a module chamber, wherein the cover includes an aperture providing fluid communication between the module chamber and atmosphere, and wherein a conduit provides fluid communication between the charging chamber and the module chamber;
• a flexible member arranged in the module chamber between the cover and the charging chamber;
• and
• a biasing member arranged between the conduit and the flexible member.
