Abstract

The present invention relates to a thermal shield 1 for at least partly surrounding a newborn infant by the shield 1 to protect it from undesired cooling or heating. The shield 1 comprises a first layer 3 and a second layer 4 both of a transparent material, which layers 3,4 are joined so that there is at least one air containing pocket 5 between the layers 3,4. When the thermal shield 1 is in use, the mutual arrangement of the first and second layers 3,4 allows the at least one pocket to be deformable to an amount necessary for establishment of acoustic contact between the skin of the infant 10 and an acoustic transducer 11 placed on an outer surface of the second layer 4. In some embodiments of the thermal shield, the at least one air containing pocket 5 is air tight, and acoustic contact can be established over an area of at least 1 cm². In other embodiments, there is at least one open passage 13 from the surroundings and into each of the at least one air pocket 5 between the first and second layers 3,4, and the compliance of the first layer 3 is higher than the compliance of the second layer 4 so that when an infant is placed in the shield 1, the first layer 3 clings around the infant while the second layer 4 deforms to a lesser extent than the first layer 3 so that air from the surroundings flows into the at least one air pocket 5 via the open passage 13.

Claims

1. A thermal shield for at least partly surrounding a newborn infant by the shield, wherein:

the shield comprises a first layer and a second layer both of a transparent material, which layers are joined so that there is at least one air containing pocket between the layers, and

the mutual arrangement of the first and second layers allows, when the thermal shield is in use, the at least one pocket to be deformable to an amount necessary for establishment of acoustic contact between the infant'"'"'s skin and an acoustic transducer placed on an outer surface of the thermal shield,

in which thermal shield;

the at least one air containing pocket is air tight, and acoustic contact can be established over an area of at least 1 cm², or

there is at least one open passage from the surroundings and into each of the at least one air pocket between the first and second layers, and the compliance of the first layer is higher than the compliance of the second layer so that when an infant is placed in the shield, the first layer clings around the infant while the second layer deforms to a lesser extent than the first layer so that air from the surroundings flows into the at least one air pocket via the open passage.

2. The thermal shield according to claim 1, further comprising:

a first opening for the infant'"'"'s head, and

a second opening with closing means adapted to vary the size of the second opening so that the second opening has a size which allows the infant to be placed in a cavity partly surrounded by the shield when the closing means are in an open condition, and so that the shield surrounds most of the infant when the closing means are in a closed condition.

3. The thermal shield according to claim 1, further comprising one or more further openings through which physical interaction with the infant is possible.

4. The thermal shield according to claim 1, comprising a plurality of air containing pockets between the first and second layers.

5. The thermal shield according to claim 1, further comprising a non-invasive temperature monitoring device for monitoring the temperature inside the shield when in use.

6. The thermal shield according to claim 5, wherein the temperature monitoring device has preset alarm limits.

7. The thermal shield according to claim 6, wherein the temperature monitoring device has a visual color indicator adapted to indicate if the temperature is below or above the preset alarm limits.

8. The thermal shield according to claim 1, further comprising a transcutaneous saturation monitor.

9. The thermal shield according to claim 1, further comprising additional insulation means arranged so that they are located between the infant and a support on which the infant is placed when the thermal shield is in use.

10. The thermal shield according to claim 9, wherein the insulation means comprises a cushion made from a polymer foam.

11. The thermal shield according to claim 9, wherein the insulation means comprises one or more air containing pockets.

12. The thermal shield according to claim 1, wherein the first layer forms an inner bag adapted to receive the infant inside it, and the second layer forms an outer bag that at least partly surrounds the inner bag.

13. The thermal shield according to claim 12, wherein the outer bag is larger than the inner bag.
