An inflatable convective thermal blanket is designed to have at least one section on its top surface that has securely mounted thereon at least one fluid absorbent mechanism for absorbing fluids from a subject that is placed onto the blanket, or from fluids fallen onto the blanket from other sources. The one section is configured onto the blanket in such a way that it forms a well for collecting the fluids. The fluid absorbent mechanism, which may be in the form of a pad, would absorb the collected fluid to thereby minimize evaporative and cooling effects on the subject. Instead of mounting it on top of the blanket, the fluid absorbent pad may be mounted to the underside of the blanket, with appropriate holes and/or openings provided at the fluid collecting section, so that the collected fluids are drained onto the fluid absorbent pad. To enhance the input flow of air to the blanket, as well as to enable the blanket to be flatly folded for storage or shipping, a collapsible retainer mechanism is provided at the input port(s) of the blanket. The retainer mechanism opens up to a shape that facilitates the mating of an air hose to the input port. When folded to its collapsed position, the retainer mechanism, and the input port, would lie substantially copfanarty with the blanket. When configured to the position for accepting the air hose, the retainer mechanism is positioned substantially orthogonal to the blanket.Linvention concerne un isolant thermique par convection et gonflable présentant, sur sa surface supérieure, au moins une section à laquelle est solidement fixé au moins un mécanisme dabsorption de fluides issus dun sujet étendu sur lisolant, ou de fluides provenant dautres sources et tombant sur lisolant. Ladite section est réalisée sur lisolant de manière à former un puits de collecte de fluides. Le mécanisme dabsorption de fluides, pouvant avoir la forme dun matelas, absorberait les fluides collectés pour ainsi réduire au minimum les effets dévaporation et
