Non-Woven Garment For Deep Vein Thrombosis Prevention
A non-woven garment for deep vein thrombosis prevention includes a body having a central panel, a left side panel, and a right side panel formed with a number of attachment straps having an integral fastener and a cover. A single air chamber receiving air from a pump through a flexible air supply tube is formed on the central penal when the body and the cover are welded through an RF welding method. The body and the cover are made of the same dielectric material for their inner layers to be welded and another same material for the outer layers which can be placed against a patient's skin. The one-step RF welding method eliminates the need for tricot lining and binding and less material is used in manufacturing. Thus, the present invention significantly reduces the manufacturing steps, time, cost, and use of material in manufacturing.
1 . A deep vein thrombosis prevention garment, comprising:
a cover;
a body having a central panel;
a left side panel extending from said central panel; and
a right side panel extending from said central panel opposite said left side panel and formed with one or more attachment straps having an integral fastener attachable to said left side panel;
wherein the cover and body are welded together along the perimeter of the garment, and
wherein the cover and body are welded together along the perimeter of the central panel to form an air chamber panel configured to receive air from an air supply tube.
2 . The deep vein thrombosis prevention garment of claim 1 , wherein the cover and body are welded using radio frequency energy.
3 . The deep vein thrombosis prevention garment of claim 1 , wherein the cover and body are constructed from an air non-permeable foam layer for their outer layer and a dielectric material for their inner layer.
4 . The deep vein thrombosis prevention garment of claim 1 , wherein the shape of the air chamber is trapezoidal.
5 . The deep vein thrombosis prevention garment of claim 1 , wherein the air supply tube is sealed to the inside layer of the central panel and the cover.
6 . The deep vein thrombosis prevention garment of claim 1 , wherein the integral fasteners are hook and loop style fasteners.
7 . The deep vein thrombosis prevention garment of claim 6 , wherein the hook portion of the hook and loop style fastener cooperates with the outer layer of the cover to secure the garment in placed when wrapped around a patient's limb.
