Reduced-pressure systems, methods, and devices for simultaneously treating a plurality of tissue sites
Systems and methods for treating a plurality of tissue sites include a multi-port therapy unit. The multi-port therapy unit includes a plurality of patient-side ports each fluidly coupled to a plurality of conduits and a fluid reservoir fluidly coupled to the plurality of ports. A plurality of pressure sensors are associated with the plurality of patient-side ports to determining a pressure associated with each conduit. A controller is operatively coupled to the plurality of pressure sensors to receive treatment pressure data, monitor pressure for each pressure sensor of the plurality of pressure sensors, and signal an alarm condition if the pressure is outside of a pre-selected range. The system includes a reduced-pressure source fluidly coupled to a dressing at each tissue site through the multi-port therapy unit.
1. A multi-port therapy unit for treating a tissue site with reduced-pressure, the multi-port therapy unit comprising:
a fluid reservoir;
at least two side ports disposed on an exterior of the multi-port therapy unit and each side port configured to fluidly couple to a delivery conduit, each side port fluidly coupled to the fluid reservoir;
a controller;
at least two pressure sensors operatively coupled to the controller, directly coupled to a respective side port of the at least two side ports and configured to generate a pressure signal corresponding to a pressure at the respective side port; and
an indicator operatively coupled to the controller and configured to display a status of a respective side port; and
wherein the controller is configured to receive the pressure signal of a side port, determine the status of the side port in response to the pressure signal, and operate the indicator to display the status.
2. The multi-port therapy unit of claim 1 , wherein the indicator is a user interface.
3. The multi-port therapy unit of claim 1 , wherein the indicator is a plurality of light emitting diodes operable to provide a color indication of pressure in response to the status determined by the controller.
4. The multi-port therapy unit of claim 1 , wherein the indicator is a plurality of indicators, each side port having a first indicator, a second indicator, and a third indicator, each indicator configured to display a status.
5. The multi-port therapy unit of claim 1 , wherein the indicator is a plurality of indicators, each side port having a first indicator, a second indicator, and a third indicator, wherein:
the first indicator is configured to display a green light and is operated by the controller when pressure at a respective side port is between about −75 mm Hg and about −150 mm Hg;
the second indicator is configured to display a yellow light and is operated by the controller if the controller determines that the pressure signal for the respective side port indicates the respective side port is losing reduced pressure; and
the third indicator is configured to display a red light and is operated by the controller to display a continuous red light when the pressure at the respective side port is not providing adequate therapy and is operated by the controller to display a flashing red light when the pressure at the respective side port is an over pressure.
