Abstract
Official abstract text for this publication.
Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. Maintenance and control of the sub atmospheric pressure exerted may be provided by such devices while minimizing discomfort to the user. The devices may be configured to be worn inconspicuously underneath clothing.
First claim
Opening claim text (preview).
What is claimed: 1. A system for treatment of a patient, the system comprising: a suction chamber with a longitudinal axis having a piston assembly configured to slide within the suction chamber along the longitudinal axis; a connector comprising a housing in releasable connection with the suction chamber; a first valve located in the housing and configured to open under negative pressure in the suction chamber; and a second valve comprising a protrusion configured to open the second valve when a priming tool engages the protrusion and pushes the protrusion distally. 2. The system of claim 1 , wherein the connector has a proximal opening configured to connect with the suction chamber and a distal opening, and wherein the first valve is located between the proximal opening and the distal opening of the connector. 3. The system of claim 1 , wherein the second valve is located on the piston assembly, and wherein the second valve is configured to allow fluid to flow across the piston assembly in a direction that is parallel to the longitudinal axis of the suction chamber. 4. The system of claim 1 , wherein the second valve is covered with at least one of a hydrophobic filter, a mesh, or a charcoal filter to prevent exudates from exiting the suction chamber. 5. The system of claim 1 , wherein the second valve is configured to open when the priming tool is inserted into the suction chamber to displace the piston assembly.
