Thermal blanket with transparent upper body drape

A thermal blanket for covering and bathing a person in a thermally-controlled flow of air and providing visibility to the person's upper body, comprising:

• a inflatable covering with a head end, a foot end, two edges, and an undersurface, the inflatable covering having a configuration including a generally rectangular lower main body section and an inflatable generally rectangular upper central body section forming a continuous extension of a central portion of said lower main body section and defining a chest cover of a width less than the width of said lower main body section;
• an inflating inlet in said inflatable covering for admitting a thermally-controlled inflating medium into said inflatable covering;
• an array of apertures in said undersurface adapted for exhausting said thermally controlled inflating medium from said inflatable covering;
• and
• a non-inflatable transparent upper body drape secured to and extending laterally beyond said central body section.

A system for delivering a bath of thermally controlled medium to a patient for controlling the temperature of the patient comprising:

• means for delivering a supply of thermally-controlled air;
• a thermal blanket for covering a bathing a person in a thermally-controlled inflating medium, said thermal blanket detachably connected to said means for delivering, wherein the thermal blanket comprises:
• a flexible base sheet having top and bottom surfaces, a head end, a foot end, two side edges, and a plurality of apertures therethrough;
• an overlaying top sheet attached to a first surface of said base sheet by a plurality of seals which form said overlaying top sheet into a plurality of inflatable chambers, said apertures opening through said base sheet into said chambers;
• and
• said base sheet and said top sheet forming an inflatable generally rectangular lower main body section of a first width and an inflatable generally rectangular upper centrally body section forming a chest cover extension at said head end having a second width less than said first width;
• and
• a non-inflatable upper-body drape formed by extensions of an overlying transparent film sheet extending outwardly from said central body section.

A thermal blanket for covering and bathing a person in a thermally-controlled inflating medium, comprising:

• a flexible base sheet having top and bottom surfaces, a head end, a foot end, two side edges, and a plurality of apertures therethrough;
• an overlaying top sheet attached to a first surface of the base sheet at a plurality of locations to form a plurality of passageways for circulating an inflating medium between the top sheet and the base sheet;
• the base sheet and the top sheet forming an inflatable generally rectangular lower main body section of a first width and an inflatable generally rectangular upper central body section forming a chest cover extension at the head end having a second width less than the first width;
• and
• a non-inflatable chest drape extending laterally from the central body section.
