Abstract
A wound treatment system includes a vessel that is sized to receive a human limb. The vessel includes a chamber with an opening leading into the chamber. A removable liner lines the chamber of the vessel and forms a treatment zone. A humidifier in fluid communication with the treatment zone humidifies a solution of water and antibacterial agent. An oxygen source is in fluid communication with the treatment zone. A speaker is coupled to the vessel and emits low frequency sound waves to the chamber. A first array of light emitting diodes that emits ultraviolet light is coupled to the vessel near the opening of the treatment chamber. A second array of light emitting diodes that emits pulsed light into the chamber is coupled to the chamber. The system also includes a control panel.
Core Innovation
The invention provides a portable wound treatment system for a wounded limb. The system includes a substantially rigid, limb-sized vessel having a chamber with at least one opening, and a removable substantially gas impermeable liner that forms a sealed treatment zone around a portion of the limb. A cuff is configured to substantially form a seal with an opening of the chamber to define the gas-impermeable treatment zone distal the cuff.
The invention introduces treatment into the sealed treatment zone using a humidifier that humidifies a solution of water and an antibacterial agent. The humidifier generates adiabatically humidified water and an antibacterial mist that is delivered to the treatment zone. The system further includes an O2 source in fluid communication with the treatment zone so that O2 is introduced into the gas-impermeable treatment zone.
The system is controlled by a control panel with manual/auto controls and programmable regimens. Optional monitoring includes an oximeter and stopping or warning criteria based on a predetermined blood oxygen level. Additional therapeutic add-ons disclosed include low-frequency speaker-driven massage vibration, UV LED sterilization near the chamber opening, and IR LED pulsed or steady heating.
Claims Coverage
The partial set includes three independent claims. Across these, the inventive features focus on a portable gas-impermeable lined chamber with a sealed cuffed treatment zone and delivery of water/antibacterial mist plus O2, a limb wound treatment apparatus with a removable gas-impermeable liner and an O2/humidifying mixture tank, and a wound treatment system combining a humidifier for water/antibacterial agent, an O2 source, and a control panel.
Portable chamber with removable substantially gas impermeable liner forming a treatment zone
A wound treatment method that places the limb into a vessel comprising a portable substantially rigid chamber lined with a removable and substantially gas impermeable liner so that a substantially gas impermeable treatment zone is formed around a portion of the limb distal a cuff.
Cuffed seal around the chamber opening to define a gas-impermeable treatment zone
The method includes placing a cuff around the wounded limb to substantially form a seal with an opening of the chamber thereby forming a substantially gas impermeable treatment zone.
Mist of water and antibacterial solution introduced into the treatment zone
The method introduces a mist of water and an antibacterial solution into the treatment zone.
O2 introduced into the gas-impermeable treatment zone
The method introduces O2 into the treatment zone.
Treatment vessel with removable substantially gas impermeable liner and limb-receiving chamber
A wound treatment apparatus having a portable treatment vessel with a treatment chamber and openings sized to receive a human limb, and a removable and substantially gas impermeable liner lining the chamber and adapted to form a treatment zone around the human limb.
Mixture tank holding a humidifying agent and O2 in fluid communication with the chamber
A mixture tank that holds a humidifying agent and O2, with the mixture tank in fluid communication with the chamber of the vessel.
Humidifier configured to humidify a solution of water and antibacterial agent into the treatment zone
A wound treatment system includes a humidifier configured to humidify a solution of water and antibacterial agent, with the humidifier in fluid communication with the treatment zone.
O2 source in fluid communication with the treatment zone
The system includes an O2 source in fluid communication with the treatment zone.
Control panel
The system includes a control panel.
The independent claims cover a portable limb wound treatment method and apparatus that use a removable substantially gas impermeable liner and a sealed cuff-defined treatment zone, with delivery of a mist of water and an antibacterial solution together with O2. The independent system claim centers on combining a humidifier for a water/antibacterial solution, an O2 source, and a control panel for operating the treatment.
