Abstract
A system for treatment of a wound area of a patient including a first treatment pad comprising a plurality of Light Emitting Diodes (LEDs) for cleaning and exposing a wound area to ultraviolet light, a second treatment pad comprising removal ports for exposing the wound area to a negative pressure, and a control unit interoperably connected to the first and second treatment pads for providing a negative pressure and the ultraviolet light to the wound area.
Core Innovation
A therapy pad is provided that combines a thermal fluid flow path disposed within the therapy pad with an array of fiber optic strands disposed on the therapy pad and positioned on a side facing a wound to project ultraviolet light onto the wound. The therapy pad includes an adhesive strip disposed on the therapy pad to separate the therapy pad from the wound when the pad is placed thereover.
The thermal fluid flow path comprises an inlet fluidly coupled to a vacuum pump and an oxygen concentrator, where the inlet defines a flow path to a plurality of ports formed on the side of the therapy pad facing the wound. The inlet and the plurality of ports are adapted to provide at least one of oxygenation and vacuum therapy to the wound.
The therapy pad further includes a radio frequency antenna comprising a wire that extends along a length of the therapy pad on a surface of the therapy pad facing the wound, and is configured to deliver ultraviolet light, oxygenation and/or vacuum therapy, and thermal therapy while also administering a pulsed radio frequency signal via the radio frequency antenna.
For treating a wound area, a method is described that includes dressing the wound area with the therapy pad, administering ultra-violet light to the wound area via the therapy pad, and administering via the therapy pad at least one of vacuum therapy and oxygenation therapy to the wound area. The method further administers thermal therapy to the wound area via the therapy pad and administers a pulsed radio frequency signal to the wound area via a radio frequency antenna disposed within the therapy pad.
Claims Coverage
The independent claims are directed to a therapy pad with a thermal fluid flow path, ultraviolet delivery via fiber optic strands, oxygenation/vacuum ports, and a radio frequency antenna, and to a method of treating a wound area using the therapy pad to deliver ultraviolet, vacuum/oxygenation, thermal therapy, and a pulsed radio frequency signal. Across the independent claims, four inventive features are emphasized.
Therapy pad with thermal fluid flow path and ultraviolet fiber optic strands
A therapy pad comprising a thermal fluid flow path disposed within the therapy pad; an array of fiber optic strands disposed on the therapy pad and positioned on a side facing a wound when the pad is placed thereover to project ultraviolet light onto the wound; and an adhesive strip disposed on the therapy pad, the adhesive strip separating the therapy pad from the wound when the pad is placed thereover.
Oxygenation and vacuum therapy via thermal fluid flow path ports
The thermal fluid flow path comprising an inlet fluidly coupled to a vacuum pump and an oxygen concentrator, the inlet defining a flow path to a plurality of ports formed on the side of the therapy pad facing the wound, the inlet and the plurality of ports being adapted to provide at least one of oxygenation and vacuum therapy to the wound.
Integrated radio frequency antenna wire on wound-facing surface
A radio frequency antenna comprising a wire that extends along a length of the therapy pad on a surface of the therapy pad facing the wound.
Method delivering multiple therapies including pulsed radio frequency
A method of treating a wound area, the method comprising dressing the wound area with a therapy pad; administering ultra-violet light to the wound area via the therapy pad; administering, via the therapy pad, at least one of vacuum therapy and oxygenation therapy to the wound area; administering, via the therapy pad, thermal therapy to the wound area; and administering a pulsed radio frequency signal to the wound area via a radio frequency antenna disposed within the therapy pad.
Overall, the claim set covers a wound-focused therapy pad that integrates ultraviolet projection via fiber optic strands, oxygenation and vacuum therapy through a thermal fluid flow path with ports facing the wound, and a radio frequency antenna for administering a pulsed radio frequency signal. The method claim ties these elements together as a multi-therapy treatment of a wound area using the therapy pad.
