Abstract

A hood with a double wall portion or wall adapter for a thermotherapy device. The wall adapter works with the hood in such thermotherapy devices to lower that part of the body heat of the premature or newborn infant lost due to radiation to the cooler hood. The construction avoids inter alia problems relating to water of condensation being formed, which may drop off. The double wall portion or wall adapter is arranged on the outside of a hood portion of the hood (1). The wall adapter (2) is fastened to the hood part (1) from the outside in a simple manner. A connection structure (5) provides for connection or locking of the wall adapter (2) at the hood (1). A seal (3) extends around the wall element of the wall adapter (2) to enclose an intermediate space between the wall adapter and (2) and the hood (1).

Claims

1. A hood for a thermotherapy device, the hood comprising:

a hood portion with a hood limiting surface;

a double wall portion detachably or pivotably connected at an outside of said hood portion, wherein said double wall portion extends essentially in parallel to said limiting surface of said hood portion.

2. A hood in accordance with claim 1, wherein said double wall portion has a peripheral seal for isolatating a volume in an intermediate space defined between said double wall portion and said hood limiting surface with respect to a surrounding environment.

3. A hood in accordance with claim 2, wherein said volume in the intermediate space contains an insulation.

4. A hood in accordance with claim 3, wherein air forms said insulation between the hood portion and the double wall portion.

5. A hood in accordance with claim 3, wherein air and an insulating material form said insulation, said insulating material having pores for enclosing the air between the hood portion and the double wall portion.

6. A hood in accordance with claim 5, wherein the insulating material is transparent.

7. A hood in accordance with claim 1, further comprising a locking means for locking said double wall portion at said hood portion, at a predetermined distance from said hood.

8. A thermotherapy device hood, comprising:

a hood part with a hood limiting surface;

a wall adapter with a wall element and a connection means for detachably or pivotably connecting said wall adapter at an outside of said hood part with said wall adapter extending essentially in parallel to said limiting surface of said hood part.

9. A hood in accordance with claim 8, wherein said wall adapter has a peripheral seal for isolatating a volume in an intermediate space defined between said wall adapter and said hood limiting surface with respect to a surrounding environment.

10. A hood in accordance with claim 9, wherein said volume in the intermediate space contains insulation.

11. A hood in accordance with claim 10, wherein said insulation between the hood portion and the wall adapter comprises air.

12. A hood in accordance with claim 10, wherein said insulation between the hood portion and the wall adapter comprises air and an insulating material having pores for enclosing the air between the hood portion and the wall adapter.

13. A hood in accordance with claim 12, wherein the insulating material is transparent.

14. A hood in accordance with claim 8, wherein said connecting means comprises a locking means for locking said wall adapter at said hood part, at a predetermined distance from said hood part.

15. A method for easy removal of accumulates in a double walled thermotherapy device without causing adverse effect on a patient, the method comprising the steps of:

providing a patient bed;

providing a hood comprising an inner wall, said hood and said patient bed cooperating to provide a thermotherapy region;

providing an outer wall with a detachably or pivotably connection means for engagement with said hood, said inner wall, and said outer wall defining an intermediate space between said inner wall and said outer wall;

providing thermotherapy in said hood in said thermotherapy region;

removing said outer wall via said connection means to clean moisture, microorganisms or to view the patient only through said inner wall.

16. A method according to claim 15 further comprising the step of:

providing a peripheral seal around said outer wall to isolate said intermediate space from ambient environment.

17. A method according to claim 16 further comprising the step of:

providing an insulating material taken from materials such as air, air enclosing pores, transparent insulator or other material in said intermediate space.
