Abstract
A disposable wound-healing device is disclosed that incorporates a housing having a fluid-impermeable material having a cavity and a perimeter that can be sealed in an air-tight manner over a wound region of a patient. The device is capable of producing a negative pressure over the wound region by either removing oxygen from within the cavity, or absorbing fluid into the cavity and then removing the fluid from the cavity. The oxygen may be removed via chemical absorption, by an electrochemical cell or by a chemical reaction that cannibalizes oxygen from the cavity. The fluid may be removed through the use of osmotic or electro-osmotic cells, or through a one-way valve. The negative partial pressure over the wound region promotes healing.
Claims18
A disposable wound-therapy device comprising:
- a housing forming a cavity therein, wherein the cavity communicates with at least one opening adapted to encompass at least a portion of a wound region of a patient;
- a perimeter surrounding the at least one opening;
- means for sealing the perimeter to a surface of the patient proximate the wound region;
- a porous sponge at least partially inside the cavity and capable of retaining a fluid therein;
- a chamber in communication with the cavity;
- and
- an electrochemical cell for removing the fluid from the sponge and transporting the fluid into the chamber.
A disposable wound-therapy device comprising:
- a housing forming a cavity, wherein the cavity communicates with at least one opening adapted to encompass at least a portion of a wound region of a patient;
- a perimeter substantially surrounding the at least one opening to provide a seal between the cavity and a surface of the patient proximate the wound region;
- a retention chamber in communication with the cavity;
- and
- an electro-osmotic cell having an osmotic membrane positioned between the retention chamber and the cavity to remove fluid from within the cavity and transport the fluid into the retention chamber.
