Reduced-Pressure Systems, Dressings, Pump Assemblies And Methods

A system for providing reduced-pressure therapy, the system comprising:

• an elongated dressing comprising:
• an absorbent layer;
• a manifold;
• a dressing cover enclosing the absorbent layer and the manifold;
• a first aperture in the dressing cover;
• and
• an outlet coupled to the manifold and being accessible through the first aperture;
• an elongated pump pouch comprising:
• a pump;
• an elongated and flexible cushion;
• a pump cover enclosing the pump and the cushion;
• a second aperture in the pump cover;
• an inlet coupled to the pump and being accessible through the second aperture;
• and
• the dressing being removeably coupled to the pump pouch solely by the inlet being attached to the outlet, and the dressing cover and the pump cover contact each other while the inlet and the outlet are attached together.

A reduced-pressure treatment system comprising:

• a pump;
• an electrical circuit connected to the pump;
• a battery connected to the electrical circuit;
• a flexible cushion;
• a flexible pump cover substantially surrounding the pump, the electrical circuit, the battery, and the cushion;
• the cushion being located between the electrical circuit and a portion of the pump cover;
• and
• a dressing connection fluidly coupled to the pump.

A system for treating a tissue site, the system comprising:

• a pump configured to provide reduced pressure;
• a flexible cushion substantially surrounding at least a majority of a periphery of the pump;
• a flexible cover substantially surrounding the pump and the cushion;
• and
• a dressing connection fluidically coupled to the pump.

A reduced-pressure wound treatment system comprising:

• a pump;
• an electrical circuit board connected to the pump;
• a battery configured to power the pump, the battery flexibly coupled to and longitudinally offset from the electrical circuit board;
• a flexible cover surrounding the pump, electrical circuit board, and the battery;
• and
• a dressing connection fluidically coupled to the pump.

A reduced-pressure wound treatment system comprising:

• a dressing;
• a pump assembly coupled to the dressing, the pump assembly comprising:
• a pump;
• a battery operably powering the pump;
• a cover substantially surrounding the pump and battery;
• and
• an inductive charger operable to electrically charge the battery while the battery remains within the cover.

A method for electrically charging a reduced-pressure treatment system, the method comprising:

• placing a pump assembly, comprising a pump and a battery within a cover, adjacent to an electrical charger;
• electrically charging the battery via inductance from the charger without removing the battery from the pump assembly;
• and
• coupling the pump assembly to a wound dressing.

A method of using a reduced-pressure treatment system, the method comprising:

• aligning an inlet of a pump assembly to an outlet of a reduced-pressure dressing;
• inserting projections from one of the inlet and the outlet into openings of the other of the inlet and the outlet;
• and
• rotating the projections relative to the openings in order to interlock together the inlet and the outlet.
