Compression device with improved moisture evaporation

摘要

A method of forming a compression device including providing a wicking layer having a perimeter generally corresponding to a perimeter of the device and a surface area comprising the area bounded by the perimeter of the wicking layer. A bladder segment is provided including opposing bladder layers of air-impermeable bladder material defining an inflatable bladder. The bladder segment has a surface area less than the surface area of the wicking layer. An outer layer is provided having openings therein. A portion of the wicking layer is not overlaid by the bladder segment by virtue of the bladder segment having a smaller surface area than the surface area of the wicking layer. The portion of the wicking layer not overlaid by the bladder segment is overlaid by openings in the outer layer. A compression device is also described.

主权项

1. A compression device for applying compression treatment to a part of a wearer's body, the device comprising:
a wicking layer having a first face and a second face, the first face being adapted to be applied to skin of the wearer such that the second face faces away from the skin, the wicking layer being adapted to move moisture, the wicking layer being constructed to 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; at least one bladder having a portion defining a compression region, the at least one bladder being constructed of bladder material generally overlying the second face of the wicking layer, the at least one bladder being formed from opposing flat faces of at least one sheet of material, the bladder material having at least one first opening therethrough located outside the compression region, the wicking layer being at least partially in registration with the bladder and at least partially in registration with the at least one first opening; fasteners for securing the compression device to the wearer's body; and a second opening through the bladder material within the compression region, the at least one first opening located outside the compression region being positioned to overlay the second opening within the compression region when the device is wrapped around the part of the wearer's body and the fasteners are engaged to secure the device to the wearer's body.
