Description

[Detailed description of the invention] [Technical field] The invention is applicable to air pine surge mats, chairs,
This invention relates to air mats used as bedding sheets and mats for preventing and treating bedsores for patients.

[Background Art] Conventional air mats are disclosed in Japanese Utility Model Publication No. 55-32580, Japanese Unexamined Patent Publication No. 74360-1982, and Japanese Unexamined Patent Publication No. 57-31859.
As shown in the publication, air is supplied and exhausted into the air bag to inflate the air mat to perform pine surgery, and the air is ejected from the air vent hole provided on the surface of the mat to discharge air to the surface of the mat, that is, the patient. It was used to dry the sides.

However, with such a structure, there is a problem in that moisture accumulates under the air mat, resulting in an unhygienic condition, which is particularly harmful to patients who are bedridden for a long period of time.

[Purpose of the invention] This invention was created in view of these problems, and its purpose is to dry not only the patient side but also the underside of the mat while supporting the patient's weight using air pressure. Our goal is to provide air mats that can.

[Disclosure of the invention] The present invention separates the adjacent air bag parts 1, 1, and connects an air supply device 3 that can supply and discharge air to the supply and discharge ports 2 of the respective air bag parts 1, 1. An air vent hole 5 is formed in the air bladder section 1 of one system of the adjacent air bladder sections 1, 1 on one side of the mat, and an air vent hole 5 is formed in the air bladder section 1 of the other system on the other side of the mat. This relates to an air mat formed on the surface side, and by configuring it in this way, the above object can be achieved.

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

FIG. 1 is an explanatory diagram of the present invention, in which an air bag portion 1 is formed of a sheet-like body, and an air supply/discharge port 2 of the air bag portion 1 is shown.
A pump 6 as an air supply device 3 capable of supplying and discharging air is connected via a hose 7.

2 to 4 show a first embodiment, in which an upper sheet part 8 and a lower sheet part 4 are welded to form a meandering section between a pair of air bag parts 1 and 1 formed in a substantially comb-like shape. The air bag portion 1 is constituted by the respective air bag portions 1, 1,
1 is formed with an air supply/discharge port 2 that can supply and discharge air, and an air ejection hole 10 as an air vent hole 5 is formed in the upper sheet part 8 of the meandering air bag part 1.
The meandering air bladder section 1 is constantly inflated by the pump 6, and air is ejected from the air ejection port 10 toward the patient to dry the body and clothes, and also to reduce the pine surge effect caused by the air ejection. It is made so that you can get it. The two air bag portions 1, which are formed in a substantially comb-like shape, are connected to the pump 6.
The needles are alternately expanded and contracted to create a pine surge effect. Air vent holes 5 as shown in FIG. 4 are formed in the lower sheet portion 4 of these comb-shaped air bags 1, 1, so that the lower surface of the air mat A can be dried. be.

5 to 7 show a second embodiment, in which a pair of air bags 1, 1 formed in a substantially comb-like shape are engaged with each other, and an air vent hole is formed in the upper sheet part 8 of one of the air bags 1. An air jet hole 10 is formed as shown in FIG.
An air vent hole 5 is formed in the lower sheet portion 4 of the other air bag portion 1, and the air bag is inflated and deflated by a pump 6. During the inflation, air is extracted from the air vent hole 5 and the air mat A This is to dry the bottom surface.

FIGS. 8 to 10 show a third embodiment, in which an upper sheet part 8 is arranged above the central seat part 11, a lower sheet part 4 is arranged below the central seat part 11,
The upper sheet part 8 is welded to the center sheet part 11 in a substantially band shape at appropriate intervals to form an upper air bag part 1a whose interior is continuous, and the lower face sheet part 4 is welded to the center sheet part 11 in a substantially band shape. The lower air bag part 1b is welded and the inside is connected in series, and the central seat part 1
1 and the welded part 12 of the upper sheet part 8, as well as the welded part 13 of the central sheet part 11 and the lower sheet part 4, are located approximately at the center of the comb-like air bag on the other side, and the central sheet part 11 and the upper sheet Welded part 12 with part 8
A large number of air ejection holes 10 are provided as air vent holes 5 in the lower air bag portion 1b, which are constantly inflated by the pump 6, so that the air can be ejected from the air ejection holes 10. A large number of air vent holes 5 are provided in the welded portion 13 between the central seat portion 11 and the lower sheet portion 4, and the air in the upper air bag portion 1a, which is inflated and deflated by the pump 6, is transferred to the air vent holes 5. It is designed so that it can be pulled out downwards.

It should be noted that the shape and form of the air mat A can be modified in various ways in addition to the above-mentioned embodiments.

In FIGS. 8 and 10, the black circle indicates the large diameter portion of the welding tip, which increases the strength of the welding tip.

[Effects of the invention] In summary, the present invention forms an air vent hole in the air bag section of one system of adjacent air bag sections on one side of the mat, and forms an air vent hole in the air bladder section of the other system. Since the air vent holes are formed on the other side of the mat, in other words, air vent holes are formed in separate systems on both sides of the mat, and the air blown out from the air vent holes of one system on the mat surface side is used to release air from the patient's side. The underside of the pine is dried using the air blown out from the air bleed holes of other systems on the underside of the pine. Since the air is ejected from both sides using a separate system, for example, if the air is ejected alternately, it is possible to alternately dry the patient side and dry the lower side of the mat. This has the advantage of being able to dry both sides while always supporting the patient's weight with air pressure.
