Description

[Detailed description of the invention] [Technical field] The present invention relates to an air mat that prevents bedsores caused by rubbing the part of the body that touches the floor, mainly when the patient is in bed for a long time, and also promotes blood circulation through pine surge. It is.

[Background Art] Conventionally, air mats have a single function, and there has been a problem in that the optimal usage condition cannot be selected depending on the patient's condition, such as severe illness or recovery period. In addition, as shown in Fig. 5, an air mat that performs a pine surge effect by expanding and contracting the air chambers can be constructed by alternately expanding and contracting the adjacent air chambers E and F to change the position that supports the body weight. When the adjacent air chambers E and F are alternately expanded and contracted in this way, the cushioning properties on the contracted side are completely lost, the function of the air mattress is reduced, and you feel pain. There was a problem.

[Purpose of the invention] The present invention was made in view of the above problems, and its purpose is to enable selection of various usage forms, such as a system in which adjacent air chambers alternately expand and contract. Although the pine surge effect is repeatedly demonstrated sufficiently, the cushioning property is not reduced, and the pine surge effect is suppressed and sufficient cushioning property is obtained, so that it can be used for seriously ill patients.
Another object of the present invention is to provide an air mat that can suitably be used for patients in the recovery period, that allows the optimum use condition to be selected according to the patient's condition, and that can also perform a drying action by blowing out air.

[Disclosure of the invention] The present invention has a first air chamber 3 and a second air chamber 4 arranged in separate systems between the center seat 1 and the upper seat 2, and an air chamber extending from the first air chamber 3. A second air chamber extending from the first air chamber portion 3a and the second air chamber 4
The air chamber portions 4a are arranged alternately, and the central seat 1
A lower air chamber 5 of one system is formed between the lower seat 7 and the lower seat 7, and the first air chamber 3, the second air chamber 4, and the lower air chamber 5 are each independently connected to an air supply/discharge means 6. This relates to an air mat which is provided with an air ejection hole 18 for ejecting air upward into the lower air chamber 5, and by configuring it in this way, the above object can be achieved. In other words,
By controlling the air supply/discharge means 6, for example, while constantly inflating the lower air chamber 5, the first air chamber 3 and the second air chamber 4 are alternately expanded and contracted, thereby changing the location where the body weight is supported. The first or second air chambers 3, 4 are formed and contracted.
There is a lower air chamber 5 below which is constantly inflated.
Good cushioning properties can be maintained regardless of the alternate contraction of the first or second air chambers 3 and 4, and by controlling the air supply and discharge means, the first air chamber 3, the second air chamber 4 and Lower air chamber 5
By inflating everything in the lower air chamber 5, it is possible to eliminate the muscle surge effect and increase cushioning properties for critically ill patients.In addition, by controlling the air supply and discharge means, the air supply to the lower air chamber 5 can be cut off. While contracting the lower air chamber 5, the first
By alternately inflating and contracting the second air chambers 3 and 4, it is possible to perform pine surgery without cushioning, making it suitable for patients undergoing rehabilitation. The type of use can be selected, and the drying effect can also be performed by blowing out air from the air blowing holes.

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

The air mat main body 8 is composed of a central sheet 1, an upper sheet 2, and a lower sheet 7, which are flexible like synthetic resin sheets. The upper sheet 2 and the center sheet 1 are welded along a welding line 9 shown by a solid line in FIG. 1, and the first air chamber portion 3a branches in the upper part of FIG. 1
It is configured into two systems: the air chamber 3 and the second air chamber 4, which has a substantially comb-like shape with a second air chamber portion 4a branching downward and meshing with the first air chamber 3. The first air chamber 3 has a first piping port 1 for supplying and discharging air.
0 is led out, and a second piping port 11 for supplying and discharging air is led out to the second air chamber 4. The first and second piping ports 10 and 11 are connected to an air pump 14 via a first solenoid valve 12 and a second solenoid valve 13, as shown in FIG. Therefore, by alternately opening and closing the first and second solenoid valves 12 and 13, the first and second air chambers 3 and 4 are alternately expanded and contracted to change the weight support position, thereby suppressing the pine surge effect. It is made possible to do so. The center sheet 1 and the lower sheet 7 are welded along the welding line 15 shown by the chain line in FIG. 1, and a meandering lower air chamber 5 is formed between the center sheet 1 and the lower sheet 7. There is. A dedicated third piping port 16 is led out to the lower air chamber 5. The third piping port 16 is connected to the air pump 14 via a third solenoid valve 17. By opening the third solenoid valve 17 and sending air into the lower air chamber 5, the lower air chamber 5 can be constantly expanded. A welding line 9 between the center sheet 1 and the upper sheet 2 is formed relatively wide, and air jet holes 18 are provided at intervals along this welding line 9.

According to such a configuration, the first, second and third
Sufficient cushioning is achieved by opening the solenoid valves 12, 13, 17 and supplying air to the first and second air chambers 3, 4 and the lower air chamber 5 to inflate all the air chambers 3, 4, 5. In such cases, the air outlet 1
Air is ejected from 8 to perform a drying action [see Fig. 2a]. While inflating the lower air chamber 5 in this way, the first solenoid valve 12 and the second solenoid valve 13 are alternately controlled to open and close.
The air chamber 3 and the second air chamber 4 are alternately expanded and contracted to perform a pine surge effect that changes the support point of the body weight while maintaining the cushioning properties of the lower air chamber 5, so that even if you lean against it, the air jet will provide a drying effect. [See Figure 2 b and c]. Also, the solenoid valve 12,
13 and 17, the first and second air chambers 3 and 4 are alternately expanded and contracted while the lower air chamber 5 is contracted, thereby performing a massage action without cushioning properties during rehabilitation. [Fig. 2d,
see e]. Note that the first, second and third solenoid valves 10,
11, 17, and their controllers are collectively referred to as air supply/discharge means 6, but such air supply/discharge means 6 can be modified in various ways. There are various types of controllers as air supply/discharge control means for controlling the solenoid valves 10, 11, and 17, such as those using electronic circuit devices and automatic switching devices using relays.

By the way, by making it possible to switch between only three states as shown in FIG. By alternately inflating and contracting the cushion and by expanding both, it is possible to perform pine surgery while always maintaining cushioning properties.

[Effect of the invention] In short, the present invention configures the first air chamber and the second air chamber as separate systems between the center seat and the upper seat, and the first air chamber extending from the first air chamber.
The air chamber portions and the second air chamber portions extending from the second air chamber are arranged alternately to form one system of lower air chambers between the center seat and the lower seat, and the first air chamber , the second air chamber and the lower air chamber are each independently connected to the air supply and exhaust means, so that by controlling the air supply and exhaust means, for example, while the lower air chamber is constantly inflated, the first air chamber and the lower air chamber are By alternately expanding and contracting the two air chambers,
The part that supports the weight can be changed, and there is a lower air chamber that is constantly inflated below the contracted first or second air chamber, regardless of the alternate contraction of the first or second air chamber. It is possible to maintain good cushioning properties, and by inflating all of the first air chamber, second air chamber, and lower air chamber by controlling the air supply/exhaust means, it can be used for critically ill patients. By controlling the air supply and discharge means, the air supply to the lower air chamber is cut off to contract the lower air chamber, and the first and second air chambers are alternately expanded and contracted. By doing so, it is possible to perform pine surgery without cushioning properties, making it suitable for patients undergoing rehabilitation, and thus having the advantage of being able to select the optimal use according to the patient. Moreover, since air can be jetted out from the air jetting holes in the lower air chamber, there is an advantage that a drying effect can also be performed by the air jetting.
