Abstract

A heat therapy appliance for treatment of neonates has a lying surface on a platform bordered by side walls, a hood movable between a closed incubator position, bearing on the side walls and covering the lying surface, and an open nursing care position, a radiant heater secured on the appliance structure and directed at the lying surface, lifting devices acting on the platform, and a control device actuating the lifting devices to adjustably set an angle of inclination of the platform with respect to the horizontal. The platform is mounted so as to be adjustable in height. The control device also actuates the lifting devices in the same direction, to adjust the vertical position of the platform with respect to the side walls between a first position and a second position higher than the first position.

First claim

The invention claimed is:

1. A thermotherapy device for treating newborns, the thermotherapy device comprising:
a device structure;
a platform with a reclining surface bordered by side walls, the platform being connected to the device structure;
a hood movable between a closed incubator position, in which the hood is in contact with the side walls and covers the reclining surface, for incubator operation, and an open nursing care position releasing the bordered reclining surface for open nursing care;
a heating radiator secured to the device structure and directed at the bordered reclining surface;
a lifting means acting on the platform; and
a control means set up to make a tilt angle of the platform in relation to a horizontal plane adjustable by actuating the lifting means, wherein the platform is mounted vertically adjustably and the control means is setup, further, by actuating the lifting means in a direction, to make a vertical position of the platform in relation to the side walls adjustable at least between a first position and a second position, which is raised relative to the first position, the device structure comprising a housing chassis, a support chassis and a lifting column, the lifting means being mounted in the housing chassis and the lifting means carrying the platform in the housing chassis, the housing chassis being carried by the lifting column and the lifting column being supported on the support chassis, the control means being set up to control the operation of the lifting means and of the lifting column in such a coordinated manner that the platform rests, in a vertical position, while the lifting column is lowered and the lifting means is raised or while the lifting column is raised and the lifting means is lowered.

2. A thermotherapy device in accordance with claim 1 , wherein the lifting means comprises electrically driven telescopic devices.

3. A thermotherapy device in accordance with claim 1 , wherein the lifting means comprises slidable lattice grates, which are driven via nuts and motor-driven spindle shafts.

4. A thermotherapy device in accordance with claim 1 , wherein the lifting means comprises motor-driven pivoted levers.

5. A thermotherapy device in accordance with claim 4 , wherein:
the platform is provided in a central region with a laterally extending pin, which meshes with a vertical guide, so that the pin is displaced in the vertical guide during a raising of the platform; and
the pin rotates in the vertical guide during a pivoting of the platform.

6. A thermotherapy device in accordance with claim 1 , wherein the control means comprises a keyboard comprising four keys, the four keys comprising a first key, a second key, a third key and a fourth key, wherein the platform can be controlled via the lifting means by the keyboard comprising the four keys in such a way that the actuation of the first key brings about a pure lifting motion of the platform, such that actuation of the second key brings about a pure lowering motion of the platform, such that the actuation of the third key brings about a pure tilting motion of the platform in one direction, and such that the actuation of the fourth key brings about a pure tilting motion of the platform in an opposite direction.

7. A thermotherapy device in accordance with claim 6 , wherein the control means is set up to continue a resulting motion of the platform when one of the keys is pressed only if a corresponding key is kept pressed and to stop the resulting motion automatically when a next normal or end position is reached.

8. A thermotherapy device in accordance with claim 1 , wherein the control means is set up to determine a position of the platform relative to the heating radiator by means of actuating signals of electric motor drives and to adapt an output of the heating radiator as a function of the determined position of the platform relative to the heating radiator.

9. A thermotherapy device in accordance with claim 1 , wherein the platform does not move in a vertical direction during raising and lowering of the lifting column such that a same distance between the platform and a floor plane is maintained during raising and lowering of the lifting column in the vertical direction, the lifting column being actuated via said lifting column drive such that [ [said]] a housing and the lifting column only move linearly, wherein said housing and said lifting column only move up and down in the vertical direction.

10. A thermotherapy device for treating newborns, the thermotherapy device comprising:
a housing;
side walls supported by the housing;
a platform with a reclining surface bordered by the side walls;
a lifting device connected to the housing and lifting the platform relative to the housing;
a hood movable between a closed incubator position, in which the hood is in contact with the side walls and covers the reclining surface, for incubator operation, and an open nursing care position releasing the bordered reclining surface for open nursing care;
a heating radiator arrangement connected to the housing and directed at the reclining surface;
a control device configured to actuate the lifting device to adjustably set a tilt angle of the platform in relation to a horizontal plane and to actuate the lifting device to change a vertical position of the platform in relation to the side walls at least between a first position and a second position, which is raised relative to the first position;
a support chassis; and
a lifting column supported on the support chassis, the lifting device being mounted in the housing and the lifting device carrying the platform in the housing, the housing being carried by the lifting column, the lifting column being supported on the support chassis, the lifting column having a lifting column drive, the control device being configured to control, in a coordinated manner, both the lifting device during operation and the lifting column drive during operation including lowering the lifting column while the lifting device raises the platform and raising the lifting column while the lifting device lowers the platform.

11. A thermotherapy device in accordance with claim 10 , wherein the lifting device comprises a plurality of electrically driven telescopic devices, the control device being configured to synchronize vertical movement of the lifting column with movement of the lifting device such that the platform is maintained at a same distance from a floor plane during raising and lowering of the lifting column in a vertical direction, the lifting column being actuated via the lifting column drive such that the housing and the lifting column only move linearly, wherein the housing and the lifting column only move up and down in the vertical direction.

12. A thermotherapy device in accordance with claim 10 , wherein the lifting device comprises:
a plurality slidable lattice grates;
a plurality of nuts; and
a plurality of motor-driven spindle shafts.

13. A thermotherapy device in accordance with claim 10 , wherein the lifting device comprises a plurality of motor-driven pivoted levers.

14. A thermotherapy device in accordance with claim 13 , wherein:
the platform is provided in a central region with a laterally extending pin engaging with a vertical guide so that the pin is displaced in the vertical guide during a raising of the platform; and
the pin rotates in the vertical guide during a pivoting of the platform.

15. A thermotherapy device in accordance with claim 10 , wherein the control device comprises a keyboard comprising four keys, the four keys comprising a first key, a second
