Abstract:
1. A wound dressing apparatus, which comprises: a wound dressing member dimensioned for positioning relative to a wound bed, the wound dressing member including a top member defining an internal vacuum reservoir and having a port in communication with the vacuum reservoir for applying subatmospheric pressure to the vacuum reservoir to facilitate healing and removal of fluid from the wound bed, the wound dressing member including a visual pressure indicator associated therewith for indicating a level of pressure within the vacuum reservoir, the visual pressure indicator including an electronic position sensor, the electronic position sensor being configured to detect a position of the top member relative to the wound bed as indicative of the pressure level within the vacuum reservoir, the electronic position sensor including an electronic switch having an associated electrical contact mounted to the top member, the electronic switch being closed when the pressure level within the vacuum reservoir achieves a predetermined value.
