Abstract
Abstract A device for patient therapy in the use of wet dressings comprising, a device for generating heated moist air, and a sheet of substantially air impervious material to cover the wet dressing. Spaced portions of the sheet are secured to the patient. The generating device is coupled to the inside of the sheet intermediate the sheet and the patient to permit passage of the heated moist air onto the wet dressing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
211 words
A device for patient therapy comprising: a preheated wet dressing comprising a gauze impregnated with a sterile liquid; means for generating a continuous supply of treating fluid comprising heated moist air; a sheet of substantially air impervious material to cover the wet dressing, said sheet having a pair of opposed side edges, a pair of opposed end edges connecting the side edges, and means defining an opening in the sheet; means for securing spaced portions of the sheet to the patient comprising adhesive on the lower surfaces of the sheet adjacent opposed edges of the sheet; means for coupling the generating means to the inside of the sheet opening intermediate the sheet and the patient to permit passage of the heated moist air onto the wet dressing, the coupling means including a coupler with a lower, outwardly directed flange located inside of the sheet opening and a conduit communicating between the generating means and the coupler; and means for permitting said treating fluid to flow outwardly between the sheet and a patient comprising at least one edge of the sheet being free of attachment to the patient whereby, in use of the device, a barrierless opening is defined between the at least one free edge of the sheet and the patient.
Claim 2
Independent Claim
211 words
A device for patient therapy comprising: a preheated wet dressing comprising a gauze impregnated with a sterile liquid; means for generating a continuous supply of treating fluid comprising heated moist air; a sheet of substantially air impervious material to cover the wet dressing, said sheet having a pair of opposed side edges, a pair of opposed end edges connecting the side edges, and means defining an opening in the sheet; means for securing spaced portions of the sheet to the patient comprising adhesive on the lower surfaces of the sheet adjacent opposed edges of the sheet; means for coupling the generating means to the inside of the sheet opening intermediate the sheet and the patient to permit passage of the heated moist air onto the wet dressing, the coupling means including a coupler with a lower, outwardly directed flange located inside of the sheet opening and a conduit communicating between the generating means and the coupler; and means for permitting said treating fluid to flow outwardly between the sheet and a patient comprising at least one edge of the sheet being free of attachment to the patient whereby, in use of the device, a barrierless opening is defined between the at least one free edge of the sheet and the patient.
Claim 3
Dependent Claim
19 words
The device of claim 1 wherein the coupler is received in a slit of the sheet defining the opening.
Claim 4
Dependent Claim
27 words
The device of claim 2 including a reinforcement secured to the sheet and extending around the opening, said reinforcement having a slit aligned with the sheet slit.
Claim 5
Dependent Claim

The device of claim 1 wherein said adhesive is on the lower surfaces of the sheet adjacent opposed side edges of the sheet, and further comprising adhesive on the lower surface of the sheet adjacent one of the end edges of the sheet and extending therealong, the other end edge defining said one free edge of the sheet.
Claim 12
Dependent Claim
19 words
The device of claim 10 wherein the generating means is coupled to the sheet adjacent the one end edge.
