Abstract
A device for directly applying thermotherapeutic liquid to an area upon the surface of an afflicted patient, and methods of use thereof, are described. In particular a device for applying water-based liquid at a therapeutic temperature directly to an afflicted area in order to create a localized hyperthermia, is presented. The afflicted area may be either on the skin of the patient, or subcutaneous. The device is also effective for disinfection, irrigation, lavage, and the like, when employing a suitable solution. The liquid may also have a mild oxidizing effect, which, if greater upon afflicted than upon non-afflicted cells, would enhance the therapeutic effect in conjunction with the therapy herein described.
Claims20
A device for applying therapeutic liquid to an afflicted area of a surface of an afflicted patient's body, comprising:
- a supply means for supplying a therapeutic liquid;
- a return means for returning liquid;
- a control means for thermally regulating the therapeutic liquid;
- a negative pressure pump operatively coupled to said return means;
- an applicator interposed between said supply means and said return means, said applicator being adapted to be secured about said afflicted area;
- wherein the applicator comprises a dressing material for placement on the afflicted area and a dressing adhesive covering;
- and
- wherein the negative pressure pump is fluidly connected to the supply means such that liquid is returned to the supply means after being drawn through the applicator.
An apparatus for applying therapeutic liquid, the apparatus comprising:
- a reservoir;
- a controller operably connected to the reservoir to regulate a temperature of liquid stored in the reservoir;
- an applicator fluidly connected to the reservoir;
- a negative pressure pump fluidly connected to the applicator to draw liquid from the reservoir through the applicator;
- wherein the applicator further comprises a dressing and an adhesive covering;
- and
- wherein the negative pressure pump is fluidly connected to the reservoir such that liquid is returned to the reservoir after being drawn through the applicator.
An apparatus for applying therapeutic liquid, the apparatus comprising:
- a reservoir;
- an applicator;
- a supply line fluidly connected to the reservoir and the applicator;
- a negative pressure pump;
- a return line fluidly connected to the applicator and the negative pressure pump;
- a set-point controller operably coupled to the reservoir to regulate a temperature of therapeutic liquid stored in the reservoir;
- wherein the negative pressure pump is operable to draw liquid from the reservoir through the applicator;
- wherein the applicator further comprises a dressing and an adhesive covering;
- and
- wherein the negative pressure pump is fluidly connected to the reservoir such that liquid is returned to the reservoir after being drawn through the applicator.
An apparatus for applying therapeutic liquid, the apparatus comprising:
- a reservoir;
- an applicator;
- a supply line fluidly connected to the reservoir and the applicator;
- a negative pressure pump;
- a return line fluidly connected to the applicator and the negative pressure pump;
- a set-point controller operably coupled to the reservoir to regulate a temperature of therapeutic liquid stored in the reservoir;
- wherein the negative pressure pump is operable to draw liquid from the reservoir through the applicator;
- wherein the applicator comprises a top surface, a wall surface, an open bottom, and a receptor;
- and
- wherein the supply line is coupled to the receptor.
A method of creating localized therapeutic hyperthermia, the method comprising:
- applying heat to a liquid;
- placing an applicator over an afflicted area;
- applying a negative pressure to the applicator to provide an engagement between the applicator and the afflicted area and to draw the liquid through the applicator;
- and
- recirculating the liquid through the applicator after the liquid has been drawn through the applicator;
- and
- wherein the applicator includes a dressing and an adhesive covering.
