Abstract
An inflatable convective pad for warming a person during surgery has two ends, two sides, and at least two openings, each located in an area of the pad between the two ends and between a respective side and the center of the pad. The openings, which may be in the form of slits, allow the threading of a sheet or the person's arms through the pad to restrain the arms during surgery.
Claims23
A method of using an inflatable convective pad, comprising:
- deploying the convective pad, the convective pad comprising:
- first and second layers joined by a seal around a common periphery to form a pneumatic structure, at least the first layer being air permeable and including an air permeable surface, the second layer is opposite the first layer;
- at least one inlet port opening into the pneumatic structure;
- an elongate seal establishing a first elongate uninflatable area between the first and second layers within the common periphery, wherein the elongate seal is surrounded by the pneumatic structure, wherein the first elongate uninflatable area is at least one-half of a longitudinal length of the pneumatic structure;
- a first slit located in the first elongate uninflatable area;
- supporting a person on the first layer of the convective pad;
- threading an arm of the person through the first slit of the convective pad;
- and
- inflating the convective pad with warmed pressurized air.

- at least one inlet port opening into the pneumatic structure;
- an elongate seal establishing a first elongate uninflatable area between the first and second layers within the common periphery, wherein the first elongate uninflatable area is at least one-half of a longitudinal length of a body portion of the convective pad;
- a first slit located in the first elongate uninflatable area;
- supporting a person on the first layer of the convective pad;
- threading an arm of the person through the first slit of the convective pad;
- and
- inflating the convective pad with warmed pressurized air, wherein warmed pressurized air is transported between a side of the convective pad and the elongate seal.
