A compression device for being wrapped around a body portion of a wearer includes an inner layer and an outer cover. First and second bladder layers are secured together to define an inflatable bladder having an outer perimeter. The inner layer, outer cover and first and second bladder layers are joined together at a plurality of discrete spot welds within the outer perimeter of the inflatable bladder.
1. A compression device for being wrapped around a body portion of a wearer, the device comprising: an inner layer;an outer cover; andfirst and second bladder layers secured together to define an inflatable bladder having an outer perimeter, the inner layer, outer cover and first and second bladder
1. A compression device for being wrapped around a body portion of a wearer, the device comprising: an inner layer;an outer cover; andfirst and second bladder layers secured together to define an inflatable bladder having an outer perimeter, the inner layer, outer cover and first and second bladder layers being joined together at a plurality of spot welds spaced from the outer perimeter of the inflatable bladder and spaced from each other. 2. A compression device as set forth in claim 1 wherein the inflatable bladder is free from securement to the inner layer and the outer cover within the outer perimeter of the inflatable bladder other than at the spot welds. 3. A compression device as set forth in claim 1 wherein the inflatable bladder constitutes a proximal bladder that is configured for wrapping around the wearer's thigh, wherein only said proximal bladder has the spot welds, wherein the first and second bladder layers further define at least one other inflatable bladder that is substantially free from attachment to the inner layer and the outer cover within an outer perimeter of said other inflatable bladder. 4. A compression device as set forth in claim 1 further comprising bladder openings extending through the inflatable bladder, wherein said spot welds are generally adjacent to the openings. 5. A compression device as set forth in claim 1 wherein the inflatable bladder constitutes a proximal bladder that is configured for wrapping around the wearer's thigh, wherein only said proximal bladder has the spot welds. 6. A compression device as set forth in claim 5 wherein the first and second bladder layers further define a second inflatable bladder that is substantially free from attachment to the inner layer and the outer cover within an outer perimeter of the second inflatable bladder. 7. A compression device as set forth in claim 6 wherein the first and second bladder layers further define a third inflatable bladder that is substantially free of attachment to the inner layer and the outer cover within an outer perimeter of the third inflatable bladder. 8. A compression device as set forth in claim 1 wherein the first and second bladder layers are disposed between the inner layer and outer cover. 9. A method of making a compression device for being wrapped around a body portion of a wearer, the method comprising: forming an inflatable bladder from layers of air impermeable material by joining the layers of air impermeable material together along an outer perimeter seam defining the inflatable bladder and an inflatable portion within the outer perimeter seam; and spot welding the layers of air impermeable material to each other and to an inner layer and an outer cover of the compression device located on opposite sides of the inflatable bladder, the spot welding occurring at a plurality of spot welds in the inflatable portion of the inflatable bladder. 10. A method as set forth in claim 9 further comprising forming the inflatable bladder such that the inflatable bladder is free from securement to the inner layer and the outer cover within the outer perimeter seam of the inflatable bladder other than at the spot welds. 11. A method as set forth in claim 9 wherein the inflatable bladder constitutes a first inflatable bladder, the method further comprising forming a second inflatable bladder from the layers of air impermeable material by joining the layers of material together along a second seam defining the second inflatable bladder, the second inflatable bladder being free of the spot welds. 12. A method as set forth in claim 11 further comprising placing the layers of air impermeable material between the inner layer and the outer cover. 13. A method as set forth in claim 11 wherein the second inflatable bladder is free of connection to the inner layer and outer cover. 14. A method as set forth in claim 11 further comprising forming a third inflatable bladder from the layers of air impermeable material by joining the layers of material together along a third seam defining the third inflatable bladder, the third inflatable bladder being free of the spot welds. 15. A method as set forth in claim 9 further comprising forming openings in the inflatable bladder, wherein the openings are formed generally adjacent the spot welds.
