Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus having a bed pad whose height can be changed.

[0002]

2. Description of the Related Art Generally, in order to change the posture of a person who is difficult to change the posture due to some obstacle, the caregiver's hand is used, or the bed frame is made movable and moved electrically or manually. A lot of electric ones have been developed. Most of them tilt or lift the entire bed, and there is no one that can change the height of any part.

[0003]

By the way, when a person's hand is used to change the posture of a person who is sleeping, it is a heavy labor for a caregiver. In addition, there is a problem in that the one that moves the entire bed cannot meet the demand for the bed to partially change the height of the head, waist, and feet, and the device is large and expensive.

The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide a bed pad device which can change the height of an arbitrary portion with a simple device.

[0005]

In order to achieve the above-mentioned object, the present invention comprises a plurality of bag-shaped bed pads which are independent and whose height can be changed by the inflowing fluid, and each bed pad is provided with an on-off valve. A bed pad device is provided which is provided with a pump for sending fluid to each bed pad.

[0006]

In the above structure, the pump sends the fluid, that is, the air, to each bed pad. The height of each bed pad can be changed by changing the amount of air sent to each bed pad.

[0007]

【Example】

(Embodiment 1) As shown in FIG. 1, a bed pad 1 is made of a flexible and airtight material in the shape of a bag, and a set of four bed pads is formed. Each bed pad 1 is connected to a pump 3 for sending air by a hose 2. Further, each bed pad 1 has an opening / closing valve 4. Each bed pad 1 has a sufficient thickness so that its height can be changed, and when air is sent, it swells and its height can be changed according to the amount thereof.

In the above-mentioned structure, when the bed person wants to get up, the bed pad 1 corresponding to the head of the bed person is inflated to a high level as shown in FIG. 2, and the height of the bed pad 1 gradually increases as the bed person moves away from the head. Air is blown so that the temperature becomes low. On the contrary, when it is desired to sleep from the sitting state, the on-off valve 4 is opened to remove air, and the surface of each bed pad 1 is flattened.

The speed at which the height of the bed pad 1 changes is
Set the bed so that the person can comfortably change their posture. Also, the height adjustment should be changed according to the person sleeping. The height can be changed by setting modes such as the rising mode and the sleeping mode, and the setting can be made simpler than each setting, and if fine adjustment can be made later, it can correspond to the preference of the sleeping person. For example, in the rising mode, the bed pad corresponding to the head starts to rise first, and then the bed pad corresponding to the chest is set to inflate, so that the bed person does not go down. You can get up easily.

It is said that the circulatory function is likely to be poor when the bedridden person is bedridden. It is said that one of the causes is that when the heart is in an upright position, it is necessary to flow blood against gravity, but it is not necessary when sleeping, so that the function of the heart deteriorates. Therefore, by lowering the bed pad 1a corresponding to the foot as shown in FIG. 3, it is possible to prevent the deterioration of the function. However, on the contrary, there is a risk of blood swelling and swelling in the foot, so it is advisable to raise or lower it in time.

Further, if a bed person sleeps for a long time, bed sores occur at a site where body pressure is high, and back pain also occurs. Then, air is sent to the bed pad corresponding to the waist so as to float the waist, and this operation is performed occasionally to prevent bed slip. (Embodiment 2) In Embodiment 2, as shown in FIG. 4, a set of eight independent bed pads 1 is used. With this configuration, in addition to the operation shown in the first embodiment, the body can be tilted left and right, which is very convenient for the caregiver to change clothes. In addition, a person who sleeps can easily turn over, which helps prevent bed sores and back pain. (Embodiment 3) In this embodiment, as shown in FIG. 5, a temperature sensor 5 and a humidity sensor 6 are added to each bed pad 1. And the temperature sensor 5 detects the heat generation of the body,
For example, when the humidity sensor 6 has a humidity of 70% or more,
Since bed sores are likely to occur, air is sent to inflate the bed pad 1 at that portion. Then, the temperature is lowered and the humidity is lowered by the blown air. Further, since the position of the body is automatically displaced, it is possible to prevent the pressure from being applied to the same site, and to prevent the occurrence of bed sores. In this way, the automatic control by the sensor can deal with the case of a bed person whose sense is no longer sensitive and can reduce the labor of the caregiver. Furthermore, by blowing air to the bed pad, the inside of the bed is dried at the same time, which is effective in terms of hygiene.

The pump may be an electric type or a manual type, and the fluid to be sent may be a liquid such as water in addition to air.

[0013]

As is clear from the description of the above embodiment,
In the bed pad device of the present invention, a plurality of independent bed pads are connected to the pump so that the height of each bed pad can be arbitrarily changed. It is useful for prevention and the like, and has an effect that the device is simple and can be manufactured at low cost.
