Abstract:
1. A method of forming a compression device for applying compression treatment to a part of a wearer's body, the method comprising: forming a bladder for selectively applying compression to the wearer's body by sealing two sheets of air impermeable bladder material together, the sheets of bladder material having a thickness; and welding the two sheets of bladder material to a wicking layer along a seamline that extends from the wicking layer through the thickness of the sheets of bladder material, the wicking layer being constructed to, through capillary action, absorb moisture trapped near the part of the wearer's body, to carry the moisture away from a surface of the part of the wearer's body, and to transport the moisture within the wicking layer from locations where the moisture is abundant to areas where it is less abundant, wherein during said welding wicking fibers of the wicking layer enter the sheets of bladder material at the seamline and extend through the thickness of the sheets of bladder material from one side of the seamline to an opposite side of the seamline thereby allowing fluid to be wicked by the wicking fibers through the bladder material at the seamline.
