Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a mattress that prevents bedsores caused by rubbing the parts of the body that touch the floor when the patient is in bed for a long period of time, and also promotes blood circulation through pine surge.

[Background technology]

A conventional mat for preventing bedsores is a mat 2' formed into a bag shape from a flexible sheet, as shown in Fig. 1.
By pumping air into the bed and ejecting the air from the blow-off holes 4', a drying effect is performed to prevent and treat bedsores. However, with this kind of configuration, since it only blows out air, there is no pine surge effect.Furthermore, if the air blowing hole 4' is blocked with the body, air cannot be jetted out, making effective prevention and treatment impossible. There was a problem. In addition, as another conventional example, the third
As shown in the figure, two bag-like bodies 1'', 1'' are made to meander so as to intersect with each other, and each bag-like body 1'' is provided with an ejection hole 4''... Body 1″,
By supplying air alternately to 1", the bag-like bodies 1", 1"
Some devices are constructed so that they can alternately expand and contract and jet air from the jet holes 4'' to perform a pine surge action and a drying action.
However, with such a configuration, air is ejected from the bag-like body 1'', but if the body is in contact with the air outlet, the air outlet is blocked and the air is not ejected, making it impossible to perform the drying action. Since the amount of air is forcefully ejected by increasing the amount, the bag-like body 1″,
1'' became too hard, resulting in the problem that the desired amount of air could not be ejected at the desired hardness.Furthermore, there was a problem that it was not possible to select between the pine surge action and the drying function.

[Purpose of the invention]

The present invention has a rational configuration that does not block the nozzle hole with the body, and while it is possible to reliably perform not only the pine surge effect but also the drying effect by blowing out air, it is possible to selectively use both of these effects. To provide a mat for preventing bedsores which can be set to a desired hardness and eject air in a desired amount, thereby effectively preventing and treating bedsores.

[Disclosure of the invention]

In the present invention, three bag-like bodies 1, 1, 1 made of flexible sheets are connected to form a mat main body 2, and each of these bag-like bodies 1, 1, 1 has an air inlet 3, 3, 3 are provided, and these three bag-like bodies 1,
An air supply means is provided to alternately inflate and contract two of the bag-like bodies 1a, 1a, and the remaining bag-like bodies 1
A large number of air ejection holes 4 are provided in b, and an air continuous supply means is provided to continuously supply air to the remaining bag-like body 1b, and a means for stopping the air supply or adjustment for arbitrarily changing the air supply amount is provided. The present invention relates to a mat for preventing bedsores, which is characterized by being provided with a means, and by configuring it in this way, the above object can be achieved.

An embodiment of the present invention will be described in detail below with reference to the drawings.

The mat main body 2 is constructed by arranging three bag-like bodies 1, 1, 1 made of flexible sheets. Specifically, the bag-like bodies 1 are provided on both sides of a bag-like body 1 which is provided in a meandering manner in the longitudinal direction of the mat main body 2, and these three bag-like bodies 1 are each provided with an air supply. An entrance 3 is formed. Air supply means (not shown) for alternately inflating and deflating the two bag-like bodies 1a, 1a is connected to the air supply ports 3 of the two bag-like bodies 1a, 1a on both sides. Such an air supply means is, for example, composed of an air supply pump and an air discharge pump, and is configured to alternately supply and discharge air to the two bag-shaped bodies 1a, 1a. . The settings of such air supply means can be changed in various ways. The remaining bag-like body 1b in the center is provided with a large number of air blow-off holes 4 at appropriate intervals along its entire length, and the air inlet 3 of this remaining bag-like body 1b is used to supply air. A continuous air supply means (not shown) is arranged and connected.
The continuous air supply means may be, for example, a pump, and the amount of air supplied from the continuous air supply means is controlled by a control valve (not shown) or the like.
It is designed so that it can be changed arbitrarily.

According to such a configuration, the bag-like bodies 1a on both sides,
By respectively supplying and discharging air to 1a, the supporting state of the body is changed and a pine surge effect is performed. In addition to the body supporting action of the two bag-like bodies 1a, 1a,
The remaining bag-like body 1 also adds support to the body,
One of the two bag-like bodies 1a → the remaining bag-like body 1
Support can be performed in three stages as follows: b → the other bag-like body 1a of the two → the remaining bag-like body 1b → one of the two bag-like bodies 1a → the remaining bag-like body 1b →...
It is possible to perform an effective pine surge effect. When the body is supported by the bag-like bodies 1a, 1a on both sides, the air blow-off holes 4 of the bag-like body 1b are not blocked, and the air set to the desired amount flows from the air blow-off holes 4. Being squirted,
It has a drying effect. Depending on the situation, the air supply to the bag-like body 1b can be stopped to perform only the above-mentioned pine surge action, or conversely, only the drying action can be performed.
In this way, it can be used in a variety of ways and can effectively prevent and treat bedsores. In the example, one bag-like body 1 was made to meander and the other was inserted so as to interlock with it.
The two bag-like bodies 1a, 1a are formed into a comb-teeth shape, and the remaining bag-like body 1b is formed between these two bag-like bodies 1a, 1a.
may be located. Note that the bag-like body 1b having the air jet holes 4 is made smaller in diameter than the other bag-like body 1a.

〔Effect of the invention〕

In summary, the present invention provides two of the three bag-like bodies.
The configuration is such that the two bags alternately inflate and contract and air is ejected only from the remaining bag, so by alternately expanding and contracting the two bags, the body blows out the air outlet of the remaining bag. It does not block, and in addition to the alternate expansion and contraction of the two pouch-like bodies, the remaining pouch-like body supports the body, resulting in an effective pine surge effect.
It is possible to reliably perform the drying effect by blowing air from the remaining bag-like body, and it is also possible to select both of these effects, making it possible to effectively prevent bedsores. Since these are separated from each other, it is possible to set the desired firmness and perform drying treatment by blowing out the desired amount of air.In addition, there is an air continuous supply means that continuously supplies air to the remaining bag-like body. In addition to providing a means for stopping the air supply or an adjusting means for arbitrarily changing the amount of air supplied,
Air can be continuously supplied to an independent bag-like body with an air outlet, the air supply can be stopped, and the amount of air supplied can be adjusted. When it is cold, the air supply is stopped or the supply amount is reduced, and when it is hot in the summer, the air jet amount is increased, and in this way, the air jet is adjusted, stopped, and the expansion and contraction of the bag-like body of the other two circuits is performed. It can be used independently without any adverse effects, and can be used optimally depending on the user's preference, physical condition, or temperature.It increases the product value of mats for preventing bedsores, and especially stops the air from blowing out when it is cold in winter. There is an advantage in that even if the air blowout is stopped, the bag-shaped body of the two circuits can be inflated and deflated alternately, and the deterioration of the anti-bedsore function can be avoided even when the air jetting is stopped. Moreover, the pine surge effect and the drying effect can be used independently.
