Disposable compression sleeve
First Claim
1. A disposable sleeve for compression therapy having at least one inflatable air cell defined between a first airtight wall to be located adjacent a patient'"'"'s body to be treated and a second airtight wall, wherein each of said first and said second walls comprises an internal airtight layer made of material including polyethylene (PE) and an external layer adjacent to the internal layer, made of a porous material adapted for being penetrated by said PE when molted, to be set therein and thereby to lock said external layer to said internal layer, the internal layers of the two walls facing each other, the walls being bonded to each other along bonding seams by welding said internal layers to each other along each such seam and by molten portions of said PE from each internal layer in a zone of said welding, having penetrated and set in the porous material of the adjacent external layer, while keeping the adjacent internal and external layers non-welded to each other at areas spaced from the welding zone.

Abstract
A disposable sleeve for compression therapy, with at least one inflatable air cell defined between a first airtight wall adjacent a patient'"'"'s body to be treated and a second airtight wall. Each of the first and second walls comprises an external porous layer and an internal layer comprising air-tight polyethylene (PE). The walls are bonded by molten portions of the PE internal layer penetrating and set in their corresponding external porous layers and welded to each other, the bonding enduring at least 250 inflation-deflation cycles associated with the therapy.

14. A method of producing a disposable sleeve for compression therapy including a predetermined number of inflation deflation cycles defining one use of the sleeve, the sleeve having at least one inflatable air cell defined between a first and a second airtight walls, each of said walls including an external layer of porous material and an internal airtight layer comprising polyethylene (PE), the method comprising:
-
a) providing a first and a second internal airtight layer comprising PE, and a first and a second layer of porous material;
b) aligning said layers in a flat stack so that the two PE layers are sandwiched between the two layers of porous material;
c) bonding said flat stack of layers by pressing and melting locally said PE layers so that molten PE penetrates and sets in said porous material and welds to the adjacent PE layer, along seams defining said at least one inflatable air cell, so that said bonding can endure said predetermined number of inflation-deflation cycles. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A disposable sleeve for compression therapy, having at least one inflatable air cell defined between a first airtight wall to be located adjacent a patient'"'"'s body to be treated and a second airtight wall, wherein each of said first and said second walls comprises an internal airtight sheet made of material including polyethylene (PE) and an external sheet made of a porous material, the internal sheets of the two walls facing each other, the walls being bonded to each other along bonding seams by welding said internal sheets to each other along each such seam and by molten portions of said PE from each internal sheet in a zone of said welding, having penetrated and set in the porous material of the adjacent external sheet, while keeping the adjacent internal and external sheets non-welded to each other at areas spaced apart from the welding zone, the bonding and the walls being designed to endure a number of cycles limited to about 30,000 inflation-deflation cycles.
