Reduced pressure treatment system
A wound treatment apparatus is provided for treating tissue damage, which comprises a fluid impermeable wound cover sealed over a site for purposes of applying a reduced pressure to the site. The apparatus also can include a cover with protrusions on its surface for purposes of monitoring pressure at the site. One or more sensors can be positioned under the cover to provide feedback to a suction pump controller. The apparatus can have a miniature and portable vacuum source connected to the wound cover.
1. A system for treating a wound on a patient with reduced pressure, the system comprising:
a dressing comprising:
a matrix material to distribute suction across the wound,
a wound cover for covering the matrix material and a portion of the patient's epidermis,
a suction port coupled to the wound cover for providing reduced pressure to the matrix material, and
a reduced pressure indicator comprising:
a displaceable portion that is adapted to move when reduced pressure under the wound cover exceeds a threshold value, and
a visual indicator associated with the displaceable portion;
a reduced pressure source; and
a tubing for fluidly coupling the reduced pressure source to the suction port.
2. The system for treating a wound of claim 1 , wherein the displaceable portion comprises a collapsible wall and the visual indicator comprises an indicator member coupled to the collapsible wall, the visual indicator having an extended position and a retracted position.
3. The system for treating a wound of claim 1 ,
wherein the displaceable portion comprises a collapsible wall, having a first end and a second end;
wherein the visual indicator comprises an indicator member coupled to the first end of the collapsible wall and wherein the indicator member has an extended position and a retracted position; and
further comprising a base coupled to the second end of the collapsible wall and wherein the base is coupled to the wound cover.
4. A system for administering a reduced pressure treatment to a wound site, comprising:
a wound dressing comprising a wound cover for covering and enclosing the wound site and the surrounding normal skin at the wound site;
at least one pressure measurement device to measure pressure beneath the wound cover and configured to measure pressure beneath the wound cover in a plurality of areas; and
a vacuum system comprising:
a reduced pressure source; and
a control device configured to transmit electrical signals to control the reduced pressure source, the control device comprising a feedback system to control the reduced pressure source based on one or more pressure differentials measured using the at least one pressure measurement device.
5. A system for administering a reduced pressure treatment to a wound site, comprising:
a wound dressing comprising a wound cover for covering and enclosing the wound site and the surrounding normal skin at the wound site;
at least one pressure measurement device to measure pressure beneath the wound cover;
a vacuum system comprising;
a reduced pressure source; and
a control device configured to transmit electrical signals to control the reduced pressure source, the control device comprising a feedback system to control the reduced pressure source based on one or more pressure differentials measured using the at least one pressure measurement device;
wherein the feedback system is configured to control the pump based on a pressure differential between a suction reading outside of the pump and a pressure reading under the wound cover.
6. A system for administering a reduced pressure treatment to a wound site, comprising:
a wound dressing comprising a wound cover for covering and enclosing the wound site and the surrounding normal skin at the wound site;
at least one pressure measurement device to monitor pressure beneath the wound cover in a plurality of areas; and
a vacuum system comprising:
a reduced pressure source; and
a control device configured to transmit electrical signals to control the reduced pressure source, the control device comprising a system to control the reduced pressure source based on pressure measured using the at least one pressure measurement device.
7. The system of claim 6 , wherein the wound dressing further comprises a matrix material beneath the wound cover to distribute suction across the wound site.
8. The system of claim 6 , further comprising a suction port coupled to the wound cover for providing reduced pressure below the wound cover.
9. The system of claim 6 , further comprising a tube connecting the dressing to the reduced pressure source.
