Multi-modal wound treatment apparatus

A wound treatment apparatus comprising:

• a housing;
• a compressor pump disposed within the housing and configured for coupling to an external oxygen source and to an external wound dressing, the compressor pump further configured to deliver therapeutically effective levels of hyperbaric oxygen to the external wound dressing during a positive pressure operational mode;
• a vacuum pump disposed within the housing and configured for coupling to the external wound dressing, the vacuum pump further configured to deliver therapeutically effective levels of negative pressure to a the external wound dressing during a negative pressure operational mode;
• an oxygen concentrator disposed within the housing and operatively coupled to the compressor pump, the oxygen concentrator effective to supply oxygen enriched air to the compressor pump during the positive pressure operational mode;
• a controller disposed within the housing and operatively connected to the compressor pump, to the vacuum pump, and to the oxygen concentrator;
• a user interface functionally coupled to the controller;
• an oxygen accumulator valve operatively coupled to the controller;
• a vacuum accumulator valve operatively coupled to the controller;
• an oxygen accumulator fluidly coupled to the compressor pump via the oxygen accumulator valve;
• and
• a vacuum accumulator fluidly coupled to the vacuum pump via the vacuum accumulator valve,
• wherein the controller is responsive to commands entered at the user interface and is configured to selectively switch the apparatus between the positive pressure and negative pressure operational modes, and
• wherein the controller is further configured to selectively actuate the oxygen and vacuum accumulator valves to expedite application of positive and negative pressures at the external wound dressing during a transition mode between the positive and negative pressure operational modes.

A portable wound treatment device comprising:

• a housing comprising an exterior wall enclosing a device interior, and a user interface panel arranged in the exterior wall;
• an oxygen supply connector panel coupled to the exterior wall and including at least one oxygen supply fitting extending through the exterior wall, the oxygen supply fitting configured to couple oxygen provided by an external oxygen source into the device interior;
• a wound treatment connector panel coupled to the exterior wall and including a positive pressure fitting and a negative pressure fitting, the positive pressure fitting configured to couple oxygen under positive pressure from the device interior to an external wound dressing, and the negative pressure fitting configured to apply a negative pressure from the device to the external wound dressing and to extract wound exudate from the external wound dressing into the device;
• a wound exudate connector panel coupled to the exterior wall and including a positive exudate fitting and a negative exudate fitting extending through the exterior wall, the positive exudate fitting configured to couple wound exudate from the negative pressure fitting to an exudate container, and the negative exudate fitting configured to provide a negative pressure to an exudate container;
• a positive pressure pump disposed in the device interior and coupled to the positive pressure fitting, the positive pressure pump effective to provide oxygen under positive pressure to the positive pressure fitting during a hyperbaric oxygen treatment mode;
• a negative pressure pump disposed in the device interior and coupled to the negative pressure fitting and to the negative exudate fitting, the negative pressure pump effective to provide negative pressure to the negative pressure fitting and to the negative exudate fitting during a negative pressure treatment mode;
• an oxygen concentrator disposed in the device interior and operatively coupled to the positive pressure pump, the oxygen concentrator effective to supply oxygen enriched air to the positive pressure pump during the hyperbaric oxygen treatment mode;
• and a controller disposed in the device interior;
• an oxygen accumulator system fluidly coupled to the positive pressure pump and operatively coupled to the controller;
• a vacuum accumulator system fluidly coupled to the negative pressure pump and operatively coupled to the controller,
• wherein the controller is functionally coupled to the user interface panel, to the positive pressure pump, and to the negative pressure pump, the controller configured to activate the positive pressure pump and the oxygen concentrator during the hyperbaric oxygen treatment mode, and to activate the negative pressure pump during the negative pressure treatment mode, and
• wherein the controller is further configured to selectively actuate the oxygen and vacuum accumulator systems to facilitate application of positive and negative pressures at the external wound dressing during a device transition mode between the hyperbaric oxygen treatment mode and the negative pressure treatment mode.
