Wound dressing with vacuum reservoir
View Patent ↗A wound dressing apparatus includes a wound dressing member dimensioned for positioning relative to a wound bed. The wound dressing member including an internal vacuum reservoir and has a port in communication with the vacuum reservoir for applying subatmospheric pressure to the vacuum reservoir to facilitate removal of fluid from the wound bed. The wound dressing member includes a visual pressure indicator associated therewith for indicating a level of pressure within the vacuum reservoir. The visual pressure indicator includes color indicia having a plurality of colors corresponding to a condition of the pressure within the vacuum reservoir. The wound dressing member includes a lower absorbent member positionable adjacent the wound bed and an upper member which at least partially defines the vacuum reservoir. At least one of the top member and the lower absorbent member has the visual pressure indicator mounted thereto.
1. A wound dressing system, comprising:
a wound dressing member dimensioned for positioning relative to a wound bed, the wound dressing member including an outer member defining an internal vacuum reservoir and having a port in communication with the vacuum reservoir, the outer member having an access door mounted thereto, the access door selectively movable between a closed position substantially enclosing the vacuum reservoir and an open position permitting access to the vacuum reservoir; and
a source of vacuum in fluid communication with the port for applying subatmospheric pressure to the vacuum reservoir to facilitate treatment of the wound bed and removal of fluid from the wound bed,
wherein the wound dressing member includes a packing member positionable adjacent the wound bed,
wherein the wound dressing member includes a visual pressure indicator for indicating a level of pressure within the vacuum reservoir,
wherein the visual pressure indicator includes color indicia, the color indicia corresponding to a condition of the subatmospheric pressure within the vacuum reservoir.
2. A wound dressing system to facilitate healing, comprising:
a wound dressing member dimensioned for positioning relative to a wound bed, the wound dressing member including an outer member defining an internal vacuum reservoir and having a port in communication with the vacuum reservoir, the outer member having an access door mounted thereto, the access door selectively movable between a closed position substantially enclosing the vacuum reservoir and an open position permitting access to the vacuum reservoir; and
a source of vacuum in fluid communication with the port for applying subatmospheric pressure to the vacuum reservoir to facilitate treatment of the wound bed and removal of fluid from the wound bed,
wherein the wound dressing member includes a packing member positionable adjacent the wound bed,
wherein the wound dressing member includes a visual pressure indicator for indicating a level of pressure within the vacuum reservoir,
wherein the visual pressure indicator includes a position sensor.
3. The wound dressing according to claim 2 , wherein the visual pressure indicator includes circuit means and visible alarm means, the circuit means adapted to actuate the visible alarm means when the position sensor detects a relative positioning of the top member of the wound dressing member to provide a visual indication of the condition of the subatmospheric pressure within the vacuum reservoir.
4. A method, comprising:
providing a wound dressing member dimensioned for positioning relative to a wound bed, the wound dressing member including an outer member defining an internal vacuum reservoir and having a port in communication with the vacuum reservoir, the outer member having an access door mounted thereto, the access door selectively movable between a closed position substantially enclosing the vacuum reservoir and an open position permitting access to the vacuum reservoir; and
providing a source of vacuum for applying subatmospheric pressure to the vacuum reservoir to facilitate treatment of the wound bed and removal of fluid from the wound bed,
providing a packing member positionable adjacent the wound bed,
wherein the wound dressing member includes a visual pressure indicator for indicating a level of pressure within the vacuum reservoir,
wherein the visual pressure indicator includes one of a position sensor and color indicia corresponding to a condition of the subatmospheric pressure within the vacuum reservoir.
5. The method according to claim 4 , wherein the visual pressure indicator includes circuit means and visible alarm means, the circuit means adapted to actuate the visible alarm means when the position sensor detects a relative positioning of the top member of the wound dressing member to provide a visual indication of the condition of the subatmospheric pressure within the vacuum reservoir.
