초록 ▼

A pneumatic compression garment includes a flexible member for placement on a limb of a human body. A bladder in the flexible member defines an inflatable chamber. The bladder has an opening through which the inflatable chamber is inflated. A port mounted on the bladder has an air inlet adapted for communication with a source of pressurized air and an air outlet in communication with the inflatable chamber via the opening in the bladder. Pressurized air is delivered from into the inflatable chamber for inflating the inflatable chamber and thereby applying a compression force to the limb when the flexible member is in place on the limb. An air diverter affixed to an inside surface of a first sheet of the bladder and configured to divert air entering the inflatable chamber from directly impinging against an inside surface of a second sheet of the bladder.

대표청구항 ▼

1. A pneumatic compression garment comprising: a flexible member for placement on a limb of a human body;a bladder in the flexible member comprising first and second opposing sheets of flexible, air-impermeable material and defining an inflatable chamber, the bladder having an opening through which the inflatable chamber is inflated;a port affixed to an outside surface of the first sheet, the port having an air inlet adapted for communication with a source of pressurized air and an air outlet in communication with the inflatable chamber via the opening in the bladder for delivery of air from the source of pressurized air into the inflatable chamber for inflating the inflatable chamber and thereby applying a compression force to the limb when the flexible member is in place on the limb; andan air diverter formed of air-impermeable material, the air diverter affixed to an inside surface of the first sheet, and the air diverter having an edge overlying a portion of the opening in the bladder and configured to divert air entering the inflatable chamber from directly impinging against an inside surface of the second sheet,wherein the edge of the air diverter overlying a portion of the opening in the bladder divides the opening into a part covered by the air diverter and a part not covered by the air diverter. 2. The pneumatic compression garment of claim 1, wherein the edge of the air diverter overlying at least a portion of the opening in the bladder is between the opening in the bladder and the second sheet. 3. The pneumatic compression garment of claim 1, wherein the air-impermeable material forming the air diverter is more rigid than the material of the first and second sheets. 4. The pneumatic compression garment of claim 1, wherein the air diverter directs air entering the inflatable chamber in a direction nonorthogonal to the first and second sheets. 5. The pneumatic compression garment of claim 1, wherein the air diverter is affixed to the inside surface of the first sheet along a first and a second connecting segment such that air entering the inflatable chamber moves along the air diverter, between the first and second connecting segments. 6. The pneumatic compression garment of claim 1, wherein the edge comprises a perimeter edge of the air diverter, at least a portion of the perimeter edge overlies the opening in the bladder. 7. A pneumatic compression garment comprising: a flexible member for placement on a limb of a human body;a bladder in the flexible member comprising first and second opposing sheets of flexible, air-impermeable material and defining an inflatable chamber, the first sheet defining an opening; anda panel formed of air-impermeable material affixed to an inside surface of the first sheet, the panel having an edge between a portion of the opening in the first sheet and the second bladder sheet such that air entering the inflatable chamber through the opening is diverted from directly impinging against an inside surface of the second sheet,wherein the edge of the panel overlying a portion of the opening in the first sheet divides the opening into a part covered by the panel and a part not covered by the panel. 8. The pneumatic compression garment of claim 7, wherein the material forming the panel is more rigid than the material of the first and second sheets. 9. The pneumatic compression garment of claim 7, wherein the panel directs air entering the inflatable chamber in a direction nonorthogonal to the first and second sheets. 10. The pneumatic compression garment of claim 7, wherein the panel is affixed to the inside surface of the first sheet along a first and a second connecting segment such that air entering the inflatable chamber moves along the panel, between the first and second connecting segments. 11. The pneumatic compression garment of claim 7, wherein a portion of the air entering the inflatable chamber through the opening bypasses the edge of the panel to directly impinge against the inside surface of the second sheet.
