Manually-actuated, reduced-pressure systems for treating wounds
First Claim
1. A manually-actuated, reduced-pressure apparatus for use with a reduced-pressure system for treating tissue at a tissue site, the apparatus comprising:
- a flexible, collapsible member having an interior space, a first end, and a second end, the flexible, collapsible member operable to move between a compressed position and an extended position;
an evacuation port coupled to the flexible, collapsible member;
a reduced-pressure port fluidly coupled to the interior space of the flexible, collapsible member;
a carrier member coupled to the first end of the flexible, collapsible member;
a slider member coupled to the second end of the flexible, collapsible member and operable to slidably engage the carrier member and to move between the compressed position and the extended position; and
a constant-force biasing member operable to provide a constant force through a range of motion of the constant-force biasing member, wherein the constant-force biasing member is configured to transition from an unrolled state to a rolled state, urge at least a portion of the slider member out of the carrier member, and urge the flexible, collapsible member from the compressed position to the extended position.

Abstract
A manually-actuated, constant reduced-pressure apparatus for use with a reduced-pressure system for treating tissue at a tissue site includes a flexible, collapsible member that is operable to move between a compressed position and an extended position. The collapsible member may be disposed between a carrier member and a slider member that move between a compressed position and an extended position. The carrier member and slider member are urged away from each other by a constant-force biasing member, e.g., a constant force coil spring. As the apparatus moves from the compressed position to the extended position, a constant reduced-pressure is generated and delivered to a reduced-pressure port. Methods of manufacturing a manually-actuated, constant reduced-pressure apparatus and methods of treating a tissue site are also provided.

8. A method of manufacturing a manually-actuated, reduced-pressure apparatus, the method comprising the steps of:
-
forming a carrier member; forming a slider member, the slider member and carrier member being formed to slidably engage one another; providing a flexible, collapsible member having a first end, a second end, and an interior space and moveable between a compressed position and an extended position; coupling the first end of the flexible, collapsible member to the carrier member; coupling the second end of the flexible, collapsible member to the slider member; associating a constant-force biasing member with the carrier member and the slider member, the constant-force biasing member being operable to provide a constant force through a range of motion of the constant-force biasing member, wherein the constant-force biasing member is configured to transition from an unrolled state to a rolled state, urge at least a portion of the slider member out of the carrier member, and urge the flexible, collapsible member from the compressed position to the extended position; forming an evacuation port on the flexible, collapsible member for allowing fluid to exit the interior space of the flexible, collapsible member when being placed in the compressed position; and forming a reduced-pressure port on the flexible, collapsible member for delivering a reduced pressure from the flexible, collapsible member. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of treating a tissue site on a patient with reduced pressure, the method comprising the steps of:
-
deploying a manifold member proximate the tissue site; deploying a sealing member over the manifold member and a portion of an epidermis to form a fluid seal; coupling a reduced-pressure interface on the sealing member for providing reduced pressure to the manifold member; providing a reduced-pressure source, wherein the reduced-pressure source comprises a manually-actuated, constant reduced-pressure source for generating a reduced-pressure, the manually-actuated, constant reduced-pressure source having a reduced-pressure port, the reduced-pressure port fluidly coupled to a first end of a reduced-pressure delivery member and operable to develop a substantially constant reduced-pressure, and wherein the manually-actuated, constant reduced-pressure source comprises a constant-force biasing member configured to; provide a constant force through a range of motion of the constant-force biasing member by transitioning from an unrolled state to a rolled state, urge at least a portion of a slider member out of a carrier member, wherein the slider member and the carrier member house the constant-force biasing member, and urge the manually-actuated, constant reduced-pressure source from a compressed position to an extended position; fluidly coupling the reduced-pressure source to the reduced-pressure interface; and moving the manually-actuated, constant reduced-pressure source to the compressed position to charge the constant-force biasing member. - View Dependent Claims (15)
