Abstract

An infant warming blanket is servo controlled by a temperature probe being taped to the abdominal skin of the infant. Through use of the blanket it is possible to maintain a constant body temperature. Access to localized areas of the body is possible by removal of blanket strips to expose the area requiring attention. The blanket has a first solid section to which a second section of individual strips having varying widths are integrally attached. The electrical heating elements run through both sections.

Claims

1. A body temperature responsive transport warming blanket comprising,

a blanket having a first section integrally connected to a second section, said second section including a plurality of strips independently operable and adapted to provide access to selected areas of the body wrapped in said blanket,

electrical heating elements extending substantially throughout said first and second sections including said plurality of strips, and

an electrical control circuit including said heating elements, a power supply and a skin contact temperature sensor adapted to be attached to said body, and a temperature control means adapted to be adjusted to a predetermined desired body temperature which is substantially continuously maintained throughout operation and use of the blanket by said heating element being operative only as required and indicated by said temperature sensor to maintain said predetermined desired body temperature within a narrow range.

2. The structure of claim 1 wherein said blanket has a longitudinal axis with said plurality of strips extending laterally of the longitudinal axis.

3. The structure of claim 2 wherein said plurality of strips have longitudinal axis and widths which vary thereby being adapted to provide varying amounts of blanket coverage over different parts of said body.

4. The structure of claim 2 wherein said blanket including said plurality of strips has a width sufficient to be adapted to wrap around said body with said strips being overlapped onto said first section of said blanket.

5. The structure of claim 4 wherein said first section is adapted to underlie said body with said second section including said plurality of strips overlying said body and being adapted to be folded back to expose and give access to a selected area of said body.

6. The structure of claim 1 wherein said narrow range of temperature is further defined as being approximately ±

0.3°
