Description

Detailed Description of the Invention

[Technical field to which the invention belongs]

The present invention is to lay on a mattress or mattress. This is related to a mattress cover that helps prevent and treat pressure ulcers.
[Conventional technology]

As the most common method for warming the bed, an electric mat or an electric blanket is conventionally used. Other than that, as disclosed in Japanese Utility Model Publication No. 43-2138, the idea of a hot air futon is known in which a duct is formed in an airtight container and the hot air is circulated and heated. The inventors of the present invention invented an air control bed cover in April 28, 2000 in Japanese Patent No. 3061360 that blows warm air or cold air into the bed cover to create a comfortable sleeping environment.
[Problems to be solved by the invention]

In the technology of Japanese Patent No. 3061360 shown in the prior art section, when the air passage 5 is located on a dehumidifying net (also referred to as a breathable mat) 8 and a person sleeps on the quilt cover, the portion that hits the back The air passage is crushed and sweat from the back cannot be discharged. This increases the humidity on the back surface to 99%. In a hospital room with a room temperature of 27 ° C and a humidity of 45%, you enter the bed at 21:00 and get up at 6am to reach 99% in 8 hours. If you are a normal person, the back hiff will dry out while you wake up, and the humidity on the mattress will also return to the room humidity. Long-term beds are living on a quilt with 99% sweat and wet wet towels. Body temperature 36 ℃ Humidity 99% The skin of the hyf becomes a hotbed of yellow staphylococci, and the white and softer hive is torn and a pressure ulcer occurs.

The present invention has been made in view of the above circumstances, and aims to provide a product aimed at constantly blowing air over the back surface so that the humidity on the back surface is always 50% or less even in long-term bed life. It is.
[Means for solving problems]

The dehumidifying body pressure dispersion air mat according to the present invention is composed of a cover main body 3b and a ventilation cloth 3c that are sewn in two layers. The cover body 3b and the air passage 3c are sewn into a bag shape. At that time, the width of the dehumidifying net 8 can be reduced by the left sewing line 20 and the right sewing line 22 to make the dehumidifying net 8 cheap, and FIG. 1 shows an example thereof. When the left sewing line 20 and the right sewing line 22 are not provided, the dehumidifying net 8 is widened to fill the cover body 3b. When widened, the left ventilation path 6 and the right ventilation path 7 become unnecessary.
The blower cap 23 is provided at one place at the bottom of the ventilation cloth, and the warm air of the heating blower 1 is sent to the ventilation path 5 from this.
Further, the lower fastener 11 is sewn on the lower side of the cover main body 3b and the upper fastener 12 is sewn on the upper side, and the dehumidifying net 8 is inserted from the lower fastener 11 so as to cover the blower base 23 as shown in FIG.
A warm insulation cushion material wrapping 3a is put on the upper surface of the cover body 3b, for example, a small amount of padding, feathers, polyester cotton, or other cushioning material. Make it effective.

The body 3b is formed into a large bag shape, and a body pressure dispersion mat chamber fastener 13 is sewn on the body pressure dispersion wrap 3d to provide the body pressure dispersion mat chamber 13. See FIG. 2 and FIG. A vertical pressure body pressure dispersion mat of another patent application is inserted into the body pressure dispersion mat chamber 13 to complete an ideal dehumidification body pressure dispersion air mat for preventing pressure ulcers. It is also possible to use a commercially available body pressure dispersion mat. See FIG. 7, FIG. 8, and FIG. 9 [Embodiment of the Invention]

Embodiments of a dehumidifying body pressure dispersion air mat of the present invention will be described below with reference to the accompanying drawings.
I think that Fig. 1 should be understood from Fig. 2 and Fig. 3 to understand its structure. As shown in FIGS. 1 and 2, the cover main body 3b and the ventilation cloth 3c are fabrics having a certain size with air permeability, and are sewn on the cover main body 3b and the ventilation cloth 3c so as to overlap the ventilation path 5. create. At this time, since the dehumidifying net 8 is expensive, if it is sewn with the left sewing line 20 and the right sewing line 22 in order to reduce the width, it can be provided cheaply to the hospital bed. Sewing lines 22 and 20 are not necessary, and a full-width dehumidifying net 8 may be used. At this time, since the cover body 3b is lifted by the air blowing force, the width of the dehumidifying net 8 and the body pressure dispersion mat needs to be increased, and the cover body 3b is strongly stretched.

The ventilation cloth 3c is provided with a blower cap 23 at one part of the skirt, and is connected to the heating blower 1 so as to send warm air or cold air to the ventilation path 5.
A lower fastener 11 is provided on the lower side of the cover body 3b and an upper fastener 12 is provided on the upper side. The dehumidifying net 8 is inserted from the lower fastener 11 so as to cover the blower base 23 so that the air flows deeper than the back of the net.
Furthermore, in order to raise the dehumidifying net cheaply, the dehumidifying effect can be obtained as it is and the pressure ulcer can be prevented even if the length is shortened and not hung on the blower base 23.

A right pocket 9 is provided near the right side of the blower base 23 attached to the lower side of the ventilation cloth 3c, and a left pocket 10 is provided near the left side. The purpose of this is to provide a pocket and to evaporate an appropriate amount with warm air to be blown to obtain a healthy sleeping climate.

The greatest feature of the present invention is that if a long-term bedridden sleeps in the bedding, there will be over 500cc of sweat per 24 hours, and the humidity on the back will increase to 99% in 8 hours. In this environment, nearly 100% of long-term beds will develop pressure ulcers. In addition, bacterial growth, odor generation, and lack of sleep are caused, worsening the condition and delaying the recovery of the disease. There are several hundred kinds of pressure ulcer prevention tools on the market, but the only high quality product that can be dehumidified is Patent No. 3061360 mentioned earlier. I used this invention for the first stage redness of pressure ulcers. It was completely cured in 10 days. Proven as a preventive device The present invention was developed for the purpose of profitable products used in hospitals nationwide to treat pressure ulcers in the second stage.
When the lower fastener 11 and the upper fastener 12 are opened, the ventilation path 5 can be cleaned, the dehumidification net 8 is taken out, and the body pressure dispersion mats 8 and 18 are taken out, so that they can be washed in a home washing machine. In this case, thermal insulation cushion material 4 is ideal for hospital use if polyester flat cotton is used.

2 is a cross-sectional view taken along the line C-D in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line A-B in FIG. 2 and 3, the dehumidification net 8 and body pressure dispersion mats 8 and 18 are not inserted.
By removing the blower cap 23, opening the lower fastener 11 and the upper fastener 12 and washing them, they can be cleaned and reused after being discharged from the hospital and can be rented under the Long-Term Care Insurance Act. .

4A and 4B show positions where the dehumidifying nets 8 and 18 of FIG. 5 enter the dehumidifying net position 21 and the vertical horizontal body pressure dispersion mats 15 and 16 of FIG. It is a figure.

FIG. 10 is a diagram in which the heating blower 12 and the blower base 23 are connected, and the blown air is blown deeper from the lower surface of the dehumidifying net 8, and FIG. 11 is an enlarged view of the circle in FIG.

FIG. 14 is a diagram showing the positions of the dehumidifying net 8 and the air base 23 in the A-B cross section of FIG. 10. It is also a diagram showing the position of the blow cap 23, right pocket 9 and left pocket 10.
[The invention's effect]

In the dehumidifying body pressure dispersion air mat for treating pressure ulcer according to the first aspect of the present invention, when the dehumidifying net 8 is directly placed in the ventilation path 5, the ventilation path 5 is collapsed when a person sleeps using this. The thickness of the dehumidifying net 8 becomes the ventilation path 5 and has the effect of dehumidifying the humidity on the back surface, which is very useful for treating pressure ulcers.

The invention described in claim 2 is an invention that is effective for pressure sores that occur in the back of the head from near the shoulder. In the invention of claim 1, sufficient air does not flow to the shoulder unless the air blowing speed is increased. If the wind speed is increased, the sound of the blower will increase and it will not be possible to use it in a hospital room. It becomes a nuisance to many sick people and sleep damage.
Therefore, the invention of claim 2 was invented as a result of many experiments.
A person with a cranial nerve illness was admitted to the University of Tokyo Hospital, and a few days later, a pressure ulcer occurred, and after eight months of efforts such as Chiba Hospital and Tokyo Police Hospital, he was unable to cure completely. , Entered home care. At this time, the product of Patent No. 3061360 before the invention of this product was used and it was completely cured, but it was a constitution with a weight of 70 kg and a heavy sweat, and had to sleep twice a night.
For such people, we believe that the present invention can achieve the optimum effect.

In the invention of claim 3, the above-mentioned sick person who develops pressure ulcers who has been sleeping for a long time and cannot always change bedding will cause bacteria to grow in the bedding, causing bad odor and lack of sleep.
In addition, some people are required to disinfect this air by sending in-hospital air with the heating fan 1. It is an invention that can solve all the above problems, and the effect that can be used with confidence in hospitals is tremendous.

The dehumidifying body pressure dispersion air mat for pressure ulcer treatment of the present invention, which is formed by the cover body 3b and the ventilation cloth 3c, and further wrapped with the heat insulation cushion cloth 3a, is further combined with the body pressure dispersion cloth 3d.
