Abstract

A compression device for applying compression to a body part of a wearer has an inflatable bladder defined by first and second bladder layers and a bladder sealing line securing the first and second bladder layers to one another. A conduit is defined by spaced apart, generally opposing conduit sealing lines securing the first and second bladder layers to one another and portions of the first and second bladder layers between the conduit lines. The conduit is fluidly connected to the inflatable bladder for delivering pressurized air to the inflatable bladder. Tubing is not needed for connection to the compression device.

Claims

1. A compression device for applying compression to a body part of a wearer, the compression device comprising:

a first bladder layer integrally formed as a one-piece sheet of air impermeable material;

a second bladder layer integrally formed as a one-piece sheet of air impermeable material, the first and second bladder layers being disposed in opposing relationship to one another;

an inflatable bladder defined by the first and second bladder layers and a bladder sealing line securing the first and second bladder layers to one another; and

a plurality of conduits, each conduit being defined by spaced apart, generally opposing conduit sealing lines securing the first and second bladder layers to one another and portions of the first and second bladder layers between the conduit lines, at least one of the conduits being fluidly connected to the inflatable bladder for delivering pressurized air to the inflatable bladder;

a conduit terminal supported by the compression device and having passages therein, for each conduit at least one of the first and second bladder layers being sealingly joined to the conduit terminal at a respective one of the passages to form a fluid-tight connection between the conduit terminal and the conduit whereby the passage and conduit are in fluid communication.

2. A compression device as set forth in claim 1 wherein the conduit terminal is adapted to mount a portable air compressor unit on the compression device and to fluidly connect the air compressor unit to the conduit to deliver pressurized air from the air compressor unit to the inflatable bladder.

3. A compression device as set forth in claim 2 wherein the second bladder layer is sealingly attached to the conduit terminal.

4. A compression device as set forth in claim 2 wherein the conduit terminal is adapted for snap-together connection with the air compressor unit.

5. A compression device as set forth in claim 4 wherein the conduit terminal comprises a snap connector component for snap connection to the air compressor unit, the snap connector component including a fluid passage therein in fluid communication with the conduit and adapted for fluid communication with the air compressor unit upon connection thereto.

6. A compression device as set forth in claim 5 wherein the snap connector component comprises a receptacle.

7. A compression device as set forth in claim 2 wherein the inflatable bladder comprises a plurality of inflatable bladders formed by the first and second layers and by bladder sealing lines each of the conduits being in fluid communication with respective ones of the inflatable bladders.

8. A compression device as set forth in claim 2 in combination with the air compressor unit.

9. A compression device as set forth in claim 1 wherein the conduit terminal is molded as one piece of material.

10. A compression device as set forth in claim 1 further comprising spacing members within the conduits for spacing apart the portions of the first and second bladder layers between the conduit lines, whereby the conduits remain open during use.

11. A compression device as set forth in claim 2 wherein the spacing members each comprise an elongate body having a generally U-shaped cross section.

12. A compression device for applying compression to a body part of a wearer, the compression device comprising:

a first bladder layer integrally formed as a one-piece sheet of air impermeable material;

a second bladder layer integrally formed as a one-piece sheet of air impermeable material, the first and second bladder layers being disposed in opposing relationship to one another;

an inflatable bladder defined by the first and second bladder layers and a bladder sealing line securing the first and second bladder layers to one another; and

at least one conduit defined by spaced apart, generally opposing conduit sealing lines securing the first and second bladder layers to one another and portions of the first and second bladder layers between the conduit sealing lines, the conduit being fluidly connected to the inflatable bladder for delivering pressurized air to the inflatable bladder;

a conduit terminal supported by the compression device and having a passage therein, at least one of the first and second bladder layers being sealingly joined to the conduit terminal at a respective one of the passages to form a fluid-tight connection between the conduit terminal and the conduit whereby the passage and conduit are in fluid communication;

the conduit terminal comprising a snap connector component for snap connection to the air compressor unit, the snap connector component including a fluid passage therein in fluid communication with the conduit and adapted for fluid communication with the air compressor unit upon connection thereto.

13. A compression device as set forth in claim 12 wherein the snap connector component comprises a receptacle.

14. A compression device as set forth in claim 12 wherein the conduit terminal is molded as one piece of material.

15. A compression device as set forth in claim 12 wherein the inflatable bladder comprises a plurality of inflatable bladders formed by the first and second layers, and further comprising plural conduits each formed by bladder sealing lines and being in fluid communication with a respective one of the inflatable bladders.

16. A compression device as set forth in claim 15 wherein the conduit terminal has plural passages therein, at least one of the first and second bladder layers being secured to the conduit terminal so that each of the conduits is placed in fluid communication with a corresponding passage in the conduit terminal.

17. A method of making a compression device comprising:

sealing opposing first and second bladder layers to one another along a bladder sealing line to define an inflatable chamber, each of the first and second bladder layers being integrally formed as a one-piece sheet of air impermeable material;

sealing the first and second bladder layers to one another along opposing conduit sealing lines to define an elongate conduit in fluid communication with the inflatable chamber for delivering pressurized air to the inflatable chamber;

providing a conduit terminal including a passage therein;

joining at least one of the first and second bladder layers to the conduit terminal to establish fluid communication between the passage and the conduit.

18. A method as set forth in claim 17 wherein said sealing opposing first and second bladder layers to define the inflatable chamber and said sealing the first and second bladder layers to define the elongate conduit are performed substantially simultaneously.

19. A method as set forth in claim 17 wherein said sealing opposing first and second bladder layers to define the inflatable chamber and said sealing the first and second bladder layers to define the elongate conduit are performed by radiofrequency welding.

20. A method as set forth in claim 17 further comprising releasably securing a portable controller unit to the conduit terminal of the compression device in fluid communication with the conduit and the inflatable chamber.

21. A method as set forth in claim 20 wherein releasably securing the portable controller comprises snap-connecting the portable controller to the conduit terminal.

22. A method as set forth in claim 17 wherein joining at least one of the first and second bladder layers to the conduit terminal comprises joining the first bladder layer to the conduit terminal

23. A method as set forth in claim 22 wherein sealing the first and second bladder layers together to form a conduit comprises, following joining the first bladder layer to the conduit terminal, the step of joining the first and second bladder layers to each other and to the conduit terminal.
