Reduced pressure delivery system having a manually-activated pump for providing treatment to low-severity wounds
First Claim
1. A manually-activated reduced pressure treatment system comprising:
- a reduced-pressure manifold configured to be placed adjacent a tissue site; and
a manually-compressible pump in fluid communication with the reduced pressure manifold to deliver a reduced pressure to the tissue site, the manually-compressible pump comprising;
a flexible and compressible side wall;
first and second end caps connected at opposite ends of the side wall to form an inner chamber defined by the side wall and the end caps, the inner chamber having a volume that varies from a maximum value when the side wall is in an uncompressed position to a minimum value when the side wall is in a compressed position;
a connection port disposed in one of the first and second end caps to allow fluid communication between the inner chamber and the reduced pressure manifold;
a one-way valve disposed in one of the first end cap, the second end cap, and the side wall to allow fluid expulsion from the inner chamber;
a hydrophobic filter in communication with the one-way valve to prevent liquids from exiting the inner chamber through the one-way valve; and
an odor filter in communication with the one-way valve to eliminate odors associated with gases expelled through the one-way valve.

Abstract
A manually-activated reduced pressure treatment system includes a substantially rigid housing, and an end cap slidingly received by the housing. An inner chamber is disposed between the end cap and housing, and a volume of the inner chamber is variable in amount depending on the position of the end cap within the housing. The end cap is slidingly movable between an uncompressed position at which the volume of the inner chamber is at a maximum value and a compressed position at which the volume of the inner chamber is at a minimum value. A position indicating member is associated with the end cap and housing to indicate the position of the end cap relative to the housing at predetermined positions between the uncompressed position and the compressed position.

11. A low-profile reduced pressure treatment system comprising:
-
a reduced pressure source; a reduced pressure manifold configured to be placed adjacent a tissue site; and a substantially flat reduced pressure delivery tube fluidly connected between the reduced pressure source and the reduced pressure manifold, the tube having a substantially rectangular cross-section and a plurality of corrugations within the tube to prevent collapse of the tube during delivery of reduced pressure. - View Dependent Claims (12, 13, 14, 15)
