Surgical barrier device incorporating an inflatable thermal blanket with an attached surgical drape
View Patent ↗A surgical barrier device includes an inflatable thermal blanket with an attached surgical drape. The inflatable thermal blanket is inflatable through an inlet by a thermally-controlled inflating medium. An aperture array on the undersurface of the inflatable thermal blanket exhausts the thermally controlled inflating medium from the inflatable thermal blanket. The surgical drape extends from the inflatable thermal blanket and is sized to substantially cover the entirety of the patient's body. Where patient access is required, that drape has an opening to provide access to a surgical site.
1. A combination for use during surgery on a person, comprising:
a flexible base sheet;
a material sheet attached to a first surface of the base sheet by a plurality of seals to form an inflatable portion with a periphery;
a plurality of apertures through the base sheet within the periphery; and
a surgical drape including a drape sheet of flexible material attached to the base sheet.
2. A surgical barrier device, comprising;
an inflatable device that includes:
a base sheet with two ends, two edges, and an undersurface;
the ends, and respective edges of the base sheet forming a periphery;
the base sheet including a layer of fibrous material on which the undersurface is disposed;
a material sheet attached to the base sheet by a seal near the periphery;
an inflating inlet for admitting a thermally controlled inflating medium into the inflatable device; and
the base sheet adapted for exhausting the thermally controlled inflating medium from the inflatable device through the undersurface;
the inflatable device being sized and configured to cover one or more partial portions of a body; and
a surgical drape including a surgical drape sheet of material attached to the inflatable device and extending beyond the periphery, the surgical drape being sized and configured to cover additional portions of the body; and
an opening in the surgical drape for accessing a surgical site on the body.
3. A surgical barrier device in accordance with claim 2 , wherein the surgical drape sheet of material is attached to the base sheet.
4. A surgical barrier device in accordance with claim 3 , wherein the surgical drape sheet of material is attached to the material sheet.

6. A surgical barrier device in accordance with claim 4 , wherein the surgical drape sheet of material covers the material sheet and is attached to the material sheet near the periphery.
7. A surgical barrier device in accordance with claim 2 , further including a plurality of seals between the material sheet and the base sheet within the periphery.
8. A surgical barrier device in accordance with claim 2 wherein the inflatable device is configured to cover the pelvic region and lower extremities of the body, and the surgical drape is generally rectangular in shape.
9. A surgical barrier device in accordance with claim 8 , wherein the inflatable device has a recess at an end thereof, and the opening is adjacent to the recess.
10. A surgical barrier device in accordance with claim 2 , wherein the inflatable device is configured to cover the chest and upper extremities of the body, and the surgical drape is generally rectangular in shape.
11. A surgical barrier device in accordance with claim 2 , wherein the inflatable device has a recess at a first end thereof and a recess at a second end thereof, and the opening is adjacent to the second end recess.
12. A surgical barrier device in accordance with claim 2 , wherein the inflatable device is configured to cover the torso and upper extremities of the body, and the surgical drape is generally rectangular in shape.
13. A surgical barrier device in accordance with claim 12 , wherein the inflatable device has a recess at a first end thereof and a recess at a second end thereof, and the opening is adjacent to the second end recess.
14. A surgical barrier device in accordance with claim 2 , wherein the inflatable device is configured to cover the torso, the upper extremities and the lower extremities of the body, and the surgical drape has a generally rectangular head end portion and a pair of foot end portions separated by the opening.
15. A surgical barrier device in accordance with claim 14 , wherein the inflatable device has a recess at an end thereof, and the opening is adjacent to the recess.
16. A surgical barrier device in accordance with claim 15 , wherein the opening includes a longitudinal V-shaped notch and a transverse slit intersecting the head end of the notch.
17. A surgical barrier device in accordance with claim 2 , further including a frame for supporting an end of the surgical drape.
