Description

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

[Background Art] As shown in Fig. 1, a conventional mat for preventing bedsores consists of a mat 2' formed into a bag shape from a flexible sheet.
By pumping air into the bed and blowing the air out from the blow-off holes 5', a drying effect is achieved 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 5' is blocked with the body, air cannot be blown 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 arranged so as to interlock with each other, each bag-like body 1'' is provided with an ejection hole 5'', and the two bag-like bodies 1″,1″
The bag-like bodies 1'', 1'' are alternately supplied with air to inflate and contract them alternately, and air is jetted out from the blow-off holes 5'' to perform a pine surge effect and a drying effect. However, with such a configuration, when air is ejected from the bag-shaped body 1'', if a body comes into contact with the bag, the ejection hole is blocked, and air cannot be ejected, making it impossible to perform the drying action. Therefore, even though the amount of air being ejected is increased to forcefully eject air, the bag-shaped bodies 1'', 1'' become too hard, and as a result, the problem arises that the desired amount of air cannot be ejected at the desired hardness. It was hot. Moreover, there was a problem in that it was not possible to select between the pine surge effect and the drying function.

Japanese Patent Publication No. 53-27661 proposes a mat for preventing bedsores. The device disclosed in this publication has a large number of tubular inflatable and deflated pouches arranged in parallel, and elastic strips are arranged between the pouches, so that when the pouches are inflated, they form a bag. The body is supported by the body, and when the bag-like body is contracted, the body is supported by the stripes, so that the support point of the body changes as the bag-like body expands and contracts. A small air outlet is provided on the top surface of the bag-like body, and air is blown out from the air outlet. The expansion and contraction of the bag-like body here, combined with the elasticity of the bag-like body due to the air, is effective in avoiding local pressure on the body and changing the body position, and the jetting of air keeps the body in a dry state. Although it is effective, it has the following problems. In other words, since air is ejected from the pouch, this occurs only when the pouch is inflated, and since the body is supported by the pouch during this inflation, the air is ejected from the pouch by the body. The problem is that the blowout of air is obstructed, and the effect of the blowout of air cannot be obtained sufficiently.

[Purpose of the invention] The present invention was made in view of the above problems, and its purpose is to solve the problems in the conventional example described above, and in addition to preventing bedsores due to expansion and contraction of the bag-like body, To provide a mat for preventing bedsores which can also sufficiently prevent bedsores due to the blowing air.

[Disclosure of the Invention] The present invention has a plurality of first tubular bags arranged substantially parallel to each other at intervals, and a plurality of second tubular bags arranged between each of the first bladders. It consists of a body and a
Each of the first bag-like bodies formed to be expandable and deflated is connected to an intermittent air supply means, and each of the second bag-like bodies, which has a smaller diameter than the first bag-like body and has an air outlet formed on its upper surface, is connected to an intermittent air supply means. connected to a continuous air supply means, the first bladder being inflated to cause the first
When the body is supported by the bag-like body, the air jet from the air outlet is not obstructed by the body. The first bag-like bodies and the second bag-like bodies here may be arranged alternately in the longitudinal direction of the mat, or alternatively in the left-right direction of the mat. Furthermore, by forming the first bag-like body and the second bag-like body so that they are each connected at one end, connection with each air supply means is facilitated. The continuous air supply means can be an air pump or compressor, and the intermittent air supply means can be composed of an air pump or compressor and a valve such as a three-way valve.

Embodiments of the present invention will be described in detail below based on the drawings.

The mat main body 2 is composed of three bag-like bodies 1, 1, 1 made of flexible sheets arranged in series. Specifically, among the three bag-like bodies 1, 1, 1, a comb-like shape that becomes the second bag-like body B extends from the bag-like body 1a disposed at the center in the width direction to the entire length of the mat main body 2 in the length direction. Extending portions 4... are formed on the left and right sides of the bag-like body 1a. The remaining two bags 1 that will become the first bag A
b, 1b are arranged on the left and right sides of the central bag-like body 1a. The remaining two bags 1b are formed in a comb-like shape and are interlocked with the comb-like extensions 4 of the central bag 1a. An air inlet 3 is formed in each of the three bag-shaped bodies 1. Intermittent air supply means (not shown) for alternately inflating and deflating the left and right bag-like bodies 1b, 1b is connected to the air inlet 3 of the left and right bag-like bodies 1b, 1b. Such an intermittent air supply means may be composed of, for example, an air supply pump and an air discharge pump, and alternately supply and discharge air to the left and right bag-shaped bodies 1b, 1b. It is something. Such intermittent air supply means can be modified in various ways. The central bag-like body 1a is provided with a large number of air outlets 5 at appropriate intervals over the entire area, and air is continuously supplied to the air inlet 3 of the central bag-like body 1a. A continuous air supply means (not shown) is provided for supplying continuous air. 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).
etc., so that it can be changed arbitrarily.

In other words, a plurality of tubular first bag-like bodies A arranged substantially parallel to each other at intervals, and each first bag-like body A...
Each first bag-like body A, which is formed to be able to expand and contract freely, is connected to an intermittent air supply means, Each of the second bag-like bodies B, which has a smaller diameter than the body A and has an air outlet 5 formed on its upper surface, is connected to a continuous air supply means.

According to such a configuration, the left and right bag-like bodies 1b,
By supplying and discharging air to 1b, the support state of the body is changed and a pine surge effect is performed. , in addition to the body supporting action of the left and right bag-like bodies 1b, 1b,
In addition to the supporting action of the central pouch-like body 1a, three stages of support can be achieved, and an effective pine surge action can be performed. When the body is supported by the left and right bag-like bodies 1b, 1b, the air outlet 5 of the central bag-like body 1a is not blocked, and the amount of air from the air outlet 5 is set to the desired amount. The air is blown out and performs a drying action. Depending on the case, 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. It can be used to effectively prevent and treat bedsores. The body can be rolled by the alternate expansion and contraction of the left and right bags 1b, 1b, and the body can be made to perform a function similar to turning over in bed. Air is ejected roughly along the line for effective drying.

[Effects of the invention] In summary, the present invention moves the body support point between the first bag and the second bag due to the expansion and contraction of the first bag, and the movement of the body support point due to the air flow within the first bag. The deformation movement of the first bag-like body removes local pressure and changes the body position, so bedsores are effectively prevented. In this respect, when the body is supported by the second bag-like body, the air jet from the air outlet is not blocked by the body, and the body is well dried by the air jetted from the second bag-like body. It also prevents bedsores.
