ABSTRACT:
DESCRIPTION
1. Technical Field
The present invention relates to devices and methods for mattresses and more particularly to devices and methods for a portable water cooled mattress that is particularly suitable for use with infants and comprises an air bladder lower layer constructed of an air-proof material with an inflation and deflation opening valve, a water bladder layer positioned on a top surface of the air bladder and including a fill and empty spout valve while a pocket is formed between the water and air bladder layers suitable for inserting heating or cooling packs and an insulating layer over the water bladder.
2. Background Art
There are numerous occasions when an infant must sleep in a climate which is either too cold or too hot and it is difficult to provide a comfortable sleeping arrangement. The present invention provides a mattress which the temperature may be adjusted by the user by inserting heating or cooling pads between a water and air layer. The water layer of the mattress provides a heat sink which will retain a temperature for a given period of time and provide comfort while a baby sleeps.
The prior art patent which are relevant are as follows:
Korner, et al, U.S. Pat. No. 4,048,684 discloses an infant waterbed for use in an incubator.
Calleance, U.S. Pat. No. 4,187,569 discloses a water mattress construction with an interior parametrial air chamber. This device is useful however it does not provide a means for altering and adjusting the temperature which provides comfort for a sleeping baby.
Lane, U.S. Pat. No. 4,901,386 discloses an air adjustable water mattress. This mattress is also useful, however it does not provide a means for easily adjusting the temperature by the insertion of heating or cooling packs between a water and air layers of the mattress.
Boyd, U.S. Pat. No. 5,107,557 discloses a waterbed mattress with air cushion. This invention is also useful however it does not include a pocket area as the present for inserting heating and cooling packs for the purposes of heating the water layer as the present invention.
Boyd, U.S. Pat. No. 5,490,295 discloses a water mattress and air mattress construction like the Boyd mattress describes above does not provide a pocket between air and water layers of the mattress for purposes of heating the water of the mattress and providing a comfortable temperature for the infant sleeping on the mattress surface.
Wu, U.S. Pat. No. 5,448,788 provides a thermo electric cooling, heating mattress which comprises a thermostatic control mattress including a water pump and external heating and cooling source. This device is also useful however it does not provide an easy to use mattress as the present which includes a pocket for inserting heating and cooling packs as desired to adjust the temperature for a sleeping baby.
As will be shown below the present invention provides a portable water cooled mattress for use with infants or the like comprising an air bladder lower layer constructed of an air proof material and including an inflation and deflation opening valve, a water bladder layer positioned on the top surface of the air bladder including a fill and empty spout valve and a pocket formed between the water and air bladder suitable for inserting heating or cooling packs while an insulating layer is provided over the water bladder.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide a Portable Water Cooled Mattress that provides a means for adjusting the temperature of an infant mattress so that the infant may sleep in comfort.
It is a further object of the invention to provide a Portable Water Cooled Mattress that comprises an air bladder lower layer constructed of an air-proof material and a water bladder positioned on a top surface of the air bladder wherein a pocket is formed between the air bladder and water bladder providing a location for inserting heating or cooling packs as desired in order to maintain a comfortable temperature of the water contained in the water bladder.
It is a still further object of the invention to provide a Portable Water Cooled Mattress that includes a heat sink comprising a volume of water placed within a water bladder positioned over an air bladder chamber wherein the temperature of the water is altered by the use of heating and/or cooling packs inserted in a pocket positioned between the air and water bladders.
Accordingly, a Portable Water Cooled Mattress is provided for use with infants or the like comprising an air bladder lower layer constructed of a durable air proof material and including an inflation and deflation valve opening, a water bladder level positioned on the top surface of the air bladder and further including a fill and empty spout valve while a pocket is formed between the water bladder and air bladder which is suitable for inserting heating and/or cooling packs as desired, the water bladder provides a means for creating a heat sink which provides an extended temperature control means and which provides an extended comfort time for the baby while an insulating upper layer covers the water bladder and is used to form a surface to lay the baby upon.
