Description

[Detailed Description of the Invention] {Industrial Field of Application} The present invention relates to an improvement of a water mattress for a gear bed used in hospitals and the like.

{Prior Art} As a water mattress for a gear bed, there is one disclosed in Utility Model Application No. 1-82785 filed on July 14, 1999.

This system accommodates a plurality of water bags in a water bag container, and has a partition between the water bags that protrudes from the bottom of the water bag container, thereby bending and raising the back part of the water bag holder. This was to prevent the water bag from slipping off when the water bag was opened.

{Problem to be solved by the invention} When using a planar heater to heat the water pine tress mentioned above, it is better to lay it across the bending and rising part of the water pine tress for the heater. Because of this, the only option is to install a planar heating heater on the underside of any water bag among the multiple water bags, and since the heating surface of the heater is not in contact with all of the multiple water bags, the surface of the heater There was a temperature difference of about 10 degrees Celsius between the water bags that were in contact with the water bags and those that were not, making it impossible to control the temperature optimally for sleeping.

The present invention takes into account the above drawbacks,
This was devised for the purpose of ensuring that even if a temperature difference occurs in the water bag, it will not affect the surface of the outer bag body of the water pine mattress on which the person actually sleeps.

{Means for Solving the Problems} That is, the structure of the present invention consists of a rectangular box-shaped water bag container 1 made of open-cell elastic foam made of elastic foam, and a rectangular box-shaped water bag container 1, which has a width of a pine pad protruding from the bottom 2. It has a plurality of partition sides 3, 3'... parallel to the direction,
The entire upper surface of the water bag container 1 is covered with a waterproof liner 4, and the water bag container 1 is covered with a waterproof liner 4.
A space 5 partitioned by partition sides 3, 3'...
Water bags 6, 6'... are housed on the four waterproof liner surfaces corresponding to 5'..., and a planar heat generating heater 7 is installed on the bottom surface of any water bag 6, and the entire exterior bag body can be opened and closed freely. 8, the upper back side 9 of the outer bag 8
A water heater characterized by having a heat insulating pad 10 covering the water bags 6', 6'', etc., at a position corresponding to at least the water bags 6', 6'', which are not in contact with the planar heater 7. It is pine tress.

{Function} There is a temperature difference of about 10°C between the water bag 6 that is in contact with the sheet heating heater 7 and the water bags 6', 6'', etc. that are not in direct contact with the sheet heating heater 7. Due to the function of the heat insulating pad 10 on the back side 9 of the upper side of the outer bag body 8 corresponding to the water bags 6', 6''... which are not in contact with the water bags 6', 6''... 6″…Do not run away to the side.

In addition, the heat generated by the water bag 6 that is in contact with the planar heater 7 is transferred to the heat insulating pad 1.
Since there is no 0, it is transmitted to the upper surface of the outer bag body 8.

{Embodiment} An embodiment of the present invention will be described based on the drawings. As shown in FIGS. 1 and 2, the water bag container 1 is made of urethane foam, ,3'...
is a protrusion having an isosceles triangular cross-sectional shape, and has a plurality of protrusions in the width direction corresponding to the position closer to the head than the bent part of the gear joint bed.

The surface of the water bag container 1 is covered with a waterproof liner 4, and the partition sides 3, 3'...
In each space section 5, 5'... separated by
Water bags 6, 6' are housed therein, and a planar heater 7 is installed on the lower surface of the water bag 6 located on the foot side.

Therefore, the heat insulating pad 10 is connected to the water bags 6', 6''... which are not in contact with the sheet heating heater 7.
It is fixed in advance to the back side 9 of the upper side of the exterior bag 8, which corresponds to the position covering the surface of...

{Effect} The device of the present invention is a water bag for a gear bed that is in contact with the planar heat generating heater 7, which was seen in Utility Application No. 1-82785 filed on July 14, 1999. 6
The temperature difference of around 10℃ that occurs between the water bag 6', 6''...
Due to this function, the surface of the outer bag body 8, which is the surface on which you actually sleep, can be kept at a temperature of 3 to 5 degrees Celsius.
To provide a water mattress for a gear bed that has a temperature distribution of cold head and warm foot type and provides a comfortable sleep.
