Inflatable thermal blanket with sterile access
An apparatus for pneumatic therapy blanket with sterile access. In one embodiment, an inflatable therapy blanket, which is sterilized, has an opening in the patient's chest area. In another embodiment, a perforated seam is positioned along the longitudinal axis of the blanket between the patient's neck and the access opening. By breaking the perforation, a slit is formed, allowing access to the patient's body from outside the blanket. In another embodiment, the blanket covers only the lower portion of the patient's body and the blanket has a tape edge for attaching the blanket to the patient's body.
1. An inflatable thermal blanket for providing a conditioned gas to a portion of a body of a human and providing access to the human, said inflatable thermal blanket comprising:
a first sheet fabricated of an air permeable material;
a barrier sheet that is impermeable to the conditioned gas; and
a second sheet fabricated of an air impermeable material, said first sheet and said second sheet having a cutout portion adapted to fit about a neck of the human, said barrier sheet disposed between said first sheet and said second sheet said barrier sheet disposed adjacent to said first sheet, said second sheet attached to said first sheet at a first seam, said first seam defining an inflatable portion, said inflatable portion including:
an inlet port opening into said inflatable portion, said inlet port for receiving the conditioned gas;
a pair of outside channels positioned along opposing sides of the inflatable portion, said pair of outside channels for exhausting the conditioned air;
at least one channel formed between said pair of outside channels, said barrier sheet positioned in said at least one channel for preventing the exhaustion of the conditioned air from said at least one channel; and
an access opening positioned between said pair of outside channels, said access opening defined by a second seam joining said first sheet and said second sheet, said access opening penetrating said first sheet and said second sheet, said access opening having a lip between an edge and said second seam.

3. The inflatable thermal blanket of claim 1 wherein said barrier sheet is a continuous sheet that is air impermeable, said barrier sheet having a cutout portion adapted to fit about a neck of the human.
4. The inflatable thermal blanket of claim 1 further including a perforated seam for creating a slit.
5. The inflatable thermal blanket of claim 4 wherein said perforated seam is located between a neck cutout portion and said through-opening.
6. The inflatable thermal blanket of claim 4 wherein said perforated seam is located between said pair of outside channels.
7. An inflatable thermal blanket for providing a conditioned gas to a portion of a body of a human and providing access to the human, said inflatable thermal blanket comprising:
an inflatable portion formed from a first sheet and a second sheet, said first sheet being air permeable and said second sheet being air impermeable, said inflatable portion including:
an inlet port opening into said inflatable portion, said inlet port for receiving the conditioned gas;
a pair of outside channels positioned along opposing sides of the inflatable portion, said pair of outside channels for exhausting the conditioned air;
at least one channel formed between said pair of outside channels;
a barrier sheet positioned in said at least one channel for preventing the exhaustion of the conditioned air from a portion of said inflatable portion said barrier sheet disposed adjacent to said first sheet; and
an access opening positioned between said pair of outside channels, said through-opening defined by a second seam joining said first sheet to said second sheet, said access opening penetrating said first sheet and said second sheet, said access opening having a lip between an edge and said second seam.
8. The inflatable thermal blanket of claim 7 further including a cutout portion adapted to fit about a neck of the human.
9. The inflatable thermal blanket of claim 7 wherein said barrier sheet is a continuous sheet that is air impermeable.
10. The inflatable thermal blanket of claim 7 further including a perforated seam located between a neck cutout portion and said through-opening, said perforated seam for creating a slit.
11. The inflatable thermal blanket of claim 7 further including a perforated seam located between said pair of outside channels, said perforated seam for creating a slit.
12. The inflatable thermal blanket of claim 7 wherein said inflatable thermal blanket is sterilizable.
13. An inflatable thermal blanket for providing a conditioned gas to a portion of a body of a human and providing access to the human, said inflatable thermal blanket comprising:
an inflatable portion formed from a first sheet and a second sheet, said first sheet being air permeable and said second sheet being air impermeable, said inflatable portion including:
an inlet port opening into said inflatable portion, said inlet port for receiving the conditioned gas;
a pair of outside channels positioned along opposing sides of the inflatable portion, said pair of outside channels for exhausting the conditioned air;
at least one channel formed between said pair of outside channels; and
a barrier sheet positioned in said at least one channel for preventing the exhaustion of the conditioned air from said at least one channel said barrier sheet disposed adjacent to said first sheet; and
at least one tape strip attached to an edge of said inflatable thermal blanket, said at least one tape strip adapted for securing said inflatable thermal blanket to the human.
14. The inflatable thermal blanket of claim 13 wherein said inflatable thermal blanket is sterilizable.
15. The inflatable thermal blanket of claim 13 further including a perforated seam located between said pair of outside channels, said perforated seam for creating a slit.
16. An inflatable thermal blanket for providing a conditioned gas to a portion of a body of a human and providing access to the human, said inflatable thermal blanket comprising:
a means for forming an inflatable portion;
a means for introducing the conditioned gas into said inflatable portion;
a means for exhausting the conditioned gas from said inflatable portion;
a means for providing access through said inflatable portion; and
a means for preventing the conditioned gas from being immediately exhausted toward a patient.
17. The inflatable thermal blanket of claim 16 further including a means for preventing the conditioned gas from being exhausted towards an access opening in said inflatable portion.
18. The inflatable thermal blanket of claim 16 further including a means for providing a second access through said inflatable thermal blanket.
19. An inflatable thermal blanket for providing a conditioned gas to a portion of a body of a human and providing access to the human, said inflatable thermal blanket comprising:
a means for forming an inflatable portion;
a means for introducing the conditioned gas into said inflatable portion;
a means for exhausting the conditioned gas from said inflatable portion;
a means for providing access through said inflatable portion; and
a means for moderating a temperature of the conditioned gas in said inflatable portion.
