Reduced pressure treatment system
First Claim
1. An appliance for administering a reduced pressure treatment to a wound, comprising:
- a cover adapted to cover the wound and adapted to maintain reduced pressure between the cover and the wound; and
an absorbable matrix adapted to encourage growth of the tissue in the area of the wound into the matrix, said absorbable matrix being located between the wound and the cover;
wherein;
the absorbable matrix comprises a first absorbable portion formed from a first material having a first rate of absorption of tissue into the first absorbable portion and a second absorbable portion formed from a second material having a second rate of absorption of tissue into the second absorbable portion, the first material being different than the second material and the first rate of absorption being different than the second rate of absorption;
the cover comprises a temperature-sensitive material configured such that a user or practitioner can monitor the temperature at the site of the wound by monitoring the appearance of the cover.

Abstract
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 includes a cover with protrusions on its surface for purposes of monitoring pressure at the site. An absorbable matrix may be placed in the site of a wound to encourage tissue growth into the matrix. Temperature of the site may be monitored using a layer of temperature sensitive material and temperature sensors connected to an alarm and recording device. A vacuum pump supplies suction within the wound cover over the treatment site. A portable version of the wound treatment apparatus is also provided. Finally, a method for treating wounds using reduced pressure is provided.

12. An appliance for monitoring pressure during treatment of any body part of a patient, comprising a cover adapted to cover the body part being treated and adapted to maintain reduced pressure at the site of the body part being treated, wherein:
-
the cover comprises a plurality of protrusions, each of which is spaced apart from the other protrusions across an outside surface of the cover and configured to indicate whether a predetermined level of reduced pressure is achieved in the space between the cover and the site of the body part being treated beneath the cover; and each protrusion comprises at least one surface that is configured to be exposed to the space between the cover and the site of the body part being treated beneath the cover. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. An appliance for administering a reduced pressure treatment to a wound, comprising:
-
a cover adapted to cover the wound and adapted to maintain reduced pressure in a space between the cover and the wound; a conduit configured to supply a source of reduced pressure to the space between the cover and the wound; and a pressure monitor supported by the cover and positioned so as to be separate and spaced apart from the conduit so that the pressure monitor is not in contact with the conduit; wherein; the pressure monitor comprises at least one surface that is configured to be exposed to the reduced pressure in the space between the cover and the wound; and the pressure monitor is configured to provide a visual indication of the level of reduced pressure between the cover and the wound such that a visual inspection of the appearance of the pressure monitor provides an indication of the level of reduced pressure in the space between the cover and the wound. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

- 49. An appliance for administering a reduced pressure treatment to a wound, comprising a cover adapted to cover the wound so as to maintain reduced pressure at the site of the wound, wherein the cover comprises a plurality of protrusions positioned across an outside surface of the cover arranged so as to project away from the outside surface of the cover, the plurality of protrusions covering at least the majority of the outside surface of the cover and each having an inside surface that is configured to be in direct communication with the reduced pressure beneath the cover.

60. An appliance for administering a reduced pressure treatment to a wound, comprising:
-
a wound dressing comprising; a cover adapted to cover the wound and adapted to maintain reduced pressure in a space between the cover and the wound; and a pressure monitor comprising a protrusion protruding above a surface of the cover and configured to be displaced downward to provide a visual indication of reduced pressure being applied beneath the cover; a vacuum pump; and a conduit configured to connect the vacuum pump to the dressing. - View Dependent Claims (61, 62, 63, 64, 65, 66, 67, 68)
