Description

[Detailed description of the invention] [Technical field] The present invention provides a bed sore prevention mat for preventing bedsores that occur when going to bed during long-term medical treatment.
In particular, it relates to a pine having a plurality of air sacs, in which the pine expands and contracts by controlling the air sent into the air sacs.

[Background technology]

To prevent and treat bedsores, it is effective to avoid local pressure, promote blood circulation to prevent congestion, and keep the affected area dry. For this purpose, it has been proposed to arrange a large number of tubular air sacs that can be expanded and contracted in parallel, inflate and deflate each sac one after another, and blow out air from minute exhaust ports provided on the top of the sacs. but,
As shown in FIGS. 1 and 2, minute exhaust ports 10 are provided on the upper surface of all the air bladders 1, and every other air bladder 1 is connected to each other and connected to the air supply means 8 via a valve 7. The other air sacs 1 located between these air sacs 1 are connected to each other and connected to the air supply means 8 via a valve 7 to alternately inflate and deflate the two groups of air sacs. , air was blown out from the air sac 1 which was inflated by being supplied with air. However, air sac 1, which is inflated due to air supply,
Since the upper surface supports the body of the patient, the minute exhaust port 10 on the top surface of the air bladder 1 is blocked by the patient, and the air that blows out does not reach the affected area of the patient, resulting in bedsores due to dryness of the affected area. This method has the problem of not being able to sufficiently prevent and treat bedsores.

[Purpose of invention]

The present invention was devised in view of these points, and its purpose is to ensure the prevention and treatment effect of bedsores caused by the air ejected from the minute exhaust port of the air sac, while also being inexpensive. To provide a mat for preventing bedsores.

[Disclosure of invention]

Therefore, the present invention includes a plurality of tubular air sacs arranged approximately parallel to each other at intervals, which can be expanded and deflated, and a plurality of fumarole pipes arranged between each of the air sacs. The air supply means for supplying air to each fumarole pipe, which has a width and height smaller than the air sac and whose upper surface is lower than the air sac when inflated, has an exhaust part and operates intermittently. The device consists of a mat for preventing bedsores that is connected to the air sac through a valve that is connected to the air sac and directly to the fumarole pipe, and at least the air sac is inflated and supports the patient's body with the air sac. When you are there,
The fumarole tube that blows out air from its minute exhaust port is separated from the body, and a single air supply means can supply continuous air to the fumarole tube and intermittent air supply to the air sac. It has been made possible to do so.

The present invention will be described in detail based on the embodiment shown in Fig. 4. In the figure, 1 is a tubular air sac which has elasticity and can be expanded and contracted, and is arranged approximately parallel to each other at intervals. The air bladders 1 are connected to each other at one end by a connecting air bladder portion 3 having a smaller cross-sectional area than the air bladder 1, and a connection port 5 is provided in a portion connected to the air bladder 1 located at the end. The space between each air sac 1 is made of the same material as air sac 1, but the width and height are smaller than that of air sac 1 (X>Y, P>
Q) Fumarole pipes 2 are arranged respectively. Each fumarole pipe 2 has a large number of minute exhaust ports 10 on its upper surface and is provided so that the position of the upper surface when inflated is lower than the upper surface of the air bladder 1 when inflated.
Also, one end thereof is connected to each other by a connection air bladder portion 4, and a connection port 6 is provided. The height P of the air sac 1 and the height Q of the fumarole pipe 2 are determined by adjusting the air pressure from 0.03 to
When it is 0.20Kg/cm ² , it is preferable to set it to 100 mm or less and 70 mm or less, respectively.

The connection port 5 and the connection port 6 are connected to an air supply means 8 such as a compressor or an air pump, and the air supply means 8 and the air bladder 1 are connected through a valve 7 such as a three-way valve having an air discharge part. The air supply means 8 and the fumarole pipe 2 are connected to each other.
is directly connected. Incidentally, the diameter of the air exhaust portion of the valve 7 is 1 to 5 mm, which allows for relatively slow exhaustion. If the exhaust speed is too fast or too slow, it will have a negative effect.

In the bed sore prevention mat configured in this way, the fumarole pipe 2 is constantly expanded and the minute exhaust port 10 is expanded.
The air sac 1 repeatedly expands and contracts each time the valve 7 is switched. Further, this expansion and contraction is possible because the air sac 1 has elasticity and the connecting air sac 3
Since the cross-sectional area of is considered to be quite small, expansion is performed in order from those closest to the connection port 5 to those farthest, and contraction is performed in order from those farthest to the connection port 5. In other words, the movement of expansion and contraction of the air sac 1 creates a wave motion for the patient, which avoids local pressure due to the movement of the weight support point and promotes blood circulation.

Now, although such an operation is performed, the fumarole pipe 2, which ejects air from the minute exhaust port 10, is constantly supplied with air and is in an expanded state, and is constantly ejecting air. When the air sac 1 expands, the body of the patient is supported by the air sac 1 and moves away from the fumarole pipe 2, so that the minute exhaust port 10 of the fumarole pipe 2 is blocked by the body. Therefore, the affected area of the patient can be reliably dried by the ejected air.

[Effect of idea]

As described above, in the present invention, although the air sac expands and contracts, the fumarole pipe is constantly supplied with air and blows out air from a minute exhaust port, and the width and height of the fumarole pipe is smaller than that of the air sac. At the same time, the upper surface of the fumarole tube, where the micro-exhaust port is formed, is lower than the top surface of the air sac when it is inflated, so at least when the air sac is inflated, the micro-exhaust port of the fumarole pipe is blocked. This prevents the area from becoming stuffy and prevents local pressure from continuing due to the movement of the weight support point due to the expansion and contraction of the air sacs. Therefore, a good bed sore prevention effect can be obtained. Moreover, the air supply means for supplying air to the air bladder and each fumarole pipe,
It has an exhaust part and is connected to the air sac through an intermittently operated valve, and is also directly connected to the fumarole pipe, providing intermittent air supply to the air sac and continuous air supply to the fumarole pipe. However, only one air supply means is necessary for this purpose, and the cost required for an expensive air supply means can be reduced, so it can be provided at a low cost.
