This application is a continuation application of U.S. Ser. No. 12/061,169, filed Apr. 2, 2008 which is a continuation-in-part of U.S. Ser. No. 11/733,082, filed Apr. 9, 2007, the entire contents of which are incorporated herein by reference.
In one aspect, a compression device for being wrapped around a body portion of a wearer generally comprises 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.
In another aspect, a method of making a compression device for being wrapped around a body portion of a wearer generally comprises forming an inflatable bladder from layers of air impermeable material by joining the layers of material together along an outer perimeter seam defining the inflatable bladder. And spot welding the bladder layers 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 occurs inside the outer perimeter seam of the inflatable bladder
number of lab tests were performed to determine the embodiments of the present invention. The tests looked at the evaporation rate, wicking performance and elasticity to provide improved comfort without compromising blood flow velocity. The study used Kendall's 9529 knee length sleeve model and three other competitor models denoted as knee length sleeves A, B and C. Third party testing has demonstrated the superior performance of a full length, circumferential wrap such as Kendall's 9530. The American Journal of Surgery study “Effectiveness of Leg Compression in Preventing Venous Stasis”, concluded a sequential compression device, like Kendall's 9530 model, is best at moving blood. The study concluded that DVT prophylaxis using the 9530 leg sleeve device encounters fewer issues and problems than administering a drug such as Heparin, and the leg sleeve device was proven, to move contrast media injected in the blood along the patient's leg more effectively than the other methods described in the article.

Preferably, the inner layer 12 has an average wicking rate in terms of distance (WD60s) that is at least about 0.01 in/s (0.0254 cm/s) and an average wicking rate in terms of weight of fluid wicked (WW60s) of at least about 0.002 Ws.

With the addition of the peripheral openings 39 in the intermediate layers 14, 16 (FIG. 14) and/or the portions of the inner layer 12 not overlaid by the intermediate layers (FIG. 15), “a total open percentage” of the inner layer may be calculated, correlating to the total surface area of the inner layer not overlaid or covered by the intermediate layers 14, 16. The total open percentage of the inner layer 12 is calculated by slimming the surface areas of all portions of the inner layer that are not overlaid or covered by the intermediate layers 14, 16 and dividing this sum by the surface area of the inner layer. The surface area of the inner layer 14 is determined by the periphery dimensions of the inner layer, irrespective of any holes or openings in the layer. It is noted that the “total open percentage” of the inner layer 12 of the previous embodiment illustrated in FIGS. 1-7 is equal to the total surface area occupied by the bladder openings 32 of all the bladders 24 a, 24 b, 24 c divided by the total surface area of the bladders because the remainder of the intermediate layers 14, 16 completely overlies or covers the inner layer. However, in the present embodiments (FIGS. 14 and 15), the total open percentage of the inner layer 12 is calculated by summing the surface areas occupied by the openings 32 in the bladders 24 a, 24 b, 24 c (correlating to the total surface area of the inner layers in registration with the openings and therefore “open”) together with surface areas of any other portions of the inner layer that is not overlain or covered by the intermediate layers. In FIG. 14, the total open percentage of the inner layer 14 is equal to the sum of the areas of bladder openings 32 and the areas of the peripheral openings 39 divided by the surface area of the inner layer.

Each S-shaped bladder S1, S2, S3 is formed by securing the two intermediate layers 14, 16 together along an S-shape seam line 64. The S-shaped bladders S1, S2, S3 each include spaced apart proximal, intermediate and distal (or “first, second, and third”) sections 66, 68, 70, respectively, along the length L of the sleeve 60. The general shapes of the bladders 81, S2, S3 are indicated by a centerline in FIG. 10. Holes 72 are formed through the intermediate layers 14, 16 between the proximal and intermediate portions 66, 68, respectively, of the bladders S1, S2, S3 and the intermediate portion and distal portion 70 of the bladders. Referring to FIG. 12, instead of numerous openings 72, continuous slits 74 may extend along the width of the sleeve 60 substantially the entirety of the length of the space between disposed between the proximal and intermediate portions 66, 68 and intermediate portion and distal portion 70 of each bladder S1, S2, S3. The openings/slits 72, 74 may be other shapes and sizes. Additional opening(s) may also be formed through the intermediate layers 14, 16 between the individual bladders S1, S2, S3 to make the sleeve 60 more breathable. For example, in the illustrated embodiment, an opening 75 is located between the bladders S2 and S3. Moreover, it is understood that the S-shaped bladders may include the openings (e.g., like openings 32) through the bladders S1, S2, S3 as shown in the first embodiment without departing from the scope of the invention. Alternatively, as with the sleeve 50 embodied in FIGS. 8 and 9, the bladders S1, S2, S3 may be formed separately from separate intermediate sheets and may be spaced apart longitudinally along the sleeve 60. The remainder of the sleeve 60 may be constructed in the same manner as described above with respect to the first and second embodiments.
