DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position-holding pad, and more particularly, to bedsores (pressure sores) when a person with a limb disability, a patient waiting for an operation, etc. has been in a bed for a long time in the same posture. The present invention relates to a body position holding pad suitable for preventing the occurrence of bed slippage or the occurrence of bed slippage.

[0002]

2. Description of the Related Art Conventionally, people who have been forced to lie down for a long period of time due to injury or illness, or who use a wheelchair in the daytime, suffer from pressure sores (so-called bedsores). You have to be careful. This pressure sore is a disease that causes peripheral blood vessels in the tissue to be blocked and necrotic due to pressure received from the contact surface of the body with the mating member, and causes not only pain but also degeneration and deterioration of muscle, skin, bone tissue, etc. Invite you. Until now, so-called bed sores have been prevented by applying a cushion between a patient and a bed or by frequently changing the body position of a caregiver.

As a conventional body position holding pad for preventing such bedsores, as shown in FIG.
There is one described in JP-A-245564. The medical position holding pad 2 is formed of a synthetic resin such as urethane and has a substantially triangular cross section. The pad 2 is applied to the back of the patient 4 to prevent bedsores. I have.

[0004]

By the way, in such a conventional medical pad 2, although the patient 4 can be kept in a sideways posture, for example, air is blown between the tip of the pad 2 and the patient. However, there is a problem that bedsores are exacerbated or new bedsores are induced due to the lack of the bed. In addition, in particular, the vicinity of the spine protrudes from the back and is a part that easily becomes bedsore, and if the tip of the pad 2 comes into contact with a part that is already becoming bedsore, the symptoms will be further worsened. There was a defect.

[0005] In view of such circumstances, an object of the present invention is to provide a body position holding pad capable of improving air permeability between an affected part and a pad and contributing to prevention of bedsores.

[0006]

According to another aspect of the present invention, there is provided a body position holding pad made of a synthetic resin for preventing bedsores by being sandwiched between a mating member and a patient. , The basic shape is a substantially right triangle (A
BC) is formed from the block and the corner (B) located below the slope (P) of the block is cut off to provide a gap (X) at the junction between the patient and the floor. Features.

[0007] According to the position holding pad having such a configuration,
Since the air is exchanged through the gap (X), it is effective to prevent the deterioration of the bedsore or the occurrence of the new bedsore. Here, the upper corner portion (A) of the slope (P) may be cut off to provide a gap (Y) there. In this case, the length, that is, the height, of the side ed on the short side is reduced, so that the caregiver can easily grip the side. Further, the same effect can be exerted at the upper and lower two places.

Further, a concave groove may be provided on the slope (P). By providing such a groove, air permeability and drainage can be further improved. Further, it is preferable that a corner (B) of the triangle (ABC) is in a range of 30 ° to 33 °. Further, it is preferable that the height of the side (bc) hanging from the slope (P) is 25 to 35 mm.

It is preferable that a core is buried in the block. With such a configuration, excessive deformation of the body position holding block can be prevented. In addition, the block includes a side (a) forming a slope (P).
b), a pentagon comprising a side (bc) forming the height of the gap (X), a side (cd) forming the base, a side (de) forming the height, and a side (ae) forming the upper side. Is preferred.

With such a size, ease of use is good. Further, it is preferable that the synthetic resin is a low-rebound material having elasticity. When formed of the low resilience material in this manner, the body contact portion does not receive the pressure due to the repulsion from the pad, and it is possible to prevent induction of a new bedsore.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a body position holding pad according to an embodiment of the present invention. The body position holding pad 10 is made of a low-rebound urethane resin or the like, and has cushioning properties. Also, the position holding pad 1
Numeral 0 is a pentagonal prism having a substantially trapezoidal cross section, but the basic shape is a block composed of a substantially right-angled triangle ABC as shown in FIG. The body position holding pad 10 is formed in a shape obtained by cutting off two corners A and B of the triangular block body.

The triangle ABC is a right-angled triangle having the corner C as a right angle, and the corner A is set at about 60 ° and the corner B is set at about 30 °. Then, by removing the corners A and B, a pentagonal abcde having a trapezoidal cross section including the side ab, the side bc, the side cd, and the side de is formed. Corner B
Is cut out, a gap X is formed here, and by cutting off the corner A, a gap Y is formed here.

In such a posture holding pad 10,
The slope P composed of the side ab is a surface that normally comes into contact with the patient's back or the like. The side bc corresponds to the height of the gap X. The side cd corresponds to the bottom side of the block, the side de configures the height, and the side ae configures the upper side. Such a position holding pad 10 can be used in an appropriate place according to the needs of a patient, a user, or the like. For example, as shown in FIG. 3, the patient 12 can be kept in the lateral position by being inserted into the back of the patient 12 who is lying down. In this case, since the body position holding pad 10 is rich in cushioning properties, it is possible to disperse the pressure at the abutted portion, and to sink appropriately so that a large contact area with the patient can be secured. . Furthermore, if it is formed from an elastic low-repulsion material such as urethane foam, the pressure due to the repulsion from the pad can be suppressed, and floor slippage of the contact surface can be prevented. Therefore, even when used for a long time, the patient is not subjected to excessive pressure and does not get tired.

The urethane foam used as a low resilience material in the present embodiment is a reaction product of a polyisocyanate and a polyol, and the polyisocyanate is reacted during the polymer reaction (diisocyanate + polyol → polyurethane). Components which are gaseous at normal temperature, such as carbon dioxide gas generated by the reaction, are formed by foaming the polyurethane. Then, by changing the reaction conditions of the polyisocyanate and the polyol, the content of bubbles formed in the obtained urethane foam,
By controlling the state of the bubbles formed in the urethane foam, such as the ratio of closed cells to open cells in the bubbles, the thickness of the urethane layer forming the bubbles, and the size of the bubbles, the rebound resilience of the urethane foam Can be adjusted.

Further, according to the body position holding pad 10, a gap X is secured between the body position holding pad 10 and the back 14 in the posture shown in FIG. 3, so that the air permeability around the back 14 is improved through the gap X. Can be. Therefore, it is possible to contribute not only to prevention of bedsores but also to healing of the affected part where bedsores have already occurred.

On the other hand, such a posture holding pad 10
As shown in FIG. 4, two pieces can be used from the back to the buttocks, and in this case, it is suitable for changing diapers and the like. In addition, two posture holding pads 10 can be inserted from both sides to hold the patient on his back. In addition, the present invention is not limited to bedridden patients, and can be used by people before surgery or by people who use a wheelchair in normal life. When used in a wheelchair,
For example, it can function as a correction pad for spinal curvature or stabilize a sitting posture. Furthermore, it can be used as a pillow or as a head holding when washing hair, and it can also be used to lift legs or be sandwiched between legs.

The size of the body position holding pad 10 can be set as appropriate, but in any case, it is preferable to set the height (length) of the side bc to about 30 mm. When the length of the side bc is set to 30 mm, the height L may be set to 105 mm and the width M may be set to 170 mm.
Further, the overall length N is about 400 mm. Also,
It is desirable that the material of the main body has a hardness of 25 to 35 N and a rebound resilience of 8% or less. By doing so, it is possible to prevent the influence on the contact surface while maintaining the angle.

Here, the rebound resilience is a value measured as follows. Test piece: 50mm x 100mm x 100mm Number of samples: 3 Measuring instrument: Rebound resilience tester Test method: Place the test piece on the holder holder of the tester, drop the hard sphere freely from the specified position, and reach the maximum rebound Read the top time. This is performed three times or more for each test piece, and the highest value is set as the measured value for each test piece. The result averages each measurement.

The hardness is a value measured as follows. Test piece: 50mm x 380mm x 380mm Number of samples: 1 Measuring instrument: Instron type compression tester Test method: Place the test piece on the center of the tester table, place the pressure plate on the upper surface of the test piece and apply the load. The thickness at 5N is read to 0.1 mm, and this is set as the initial thickness. Next, after pressing the pressing plate 75% of the original thickness at a speed of 100 ± 20 mm / min, immediately remove the load and immediately press the pressing plate 25% of the initial thickness again at a speed of 100 ± 20 mm. The load when 20 seconds have passed since the standstill is read up to 1N, and the hardness (H) is the read load. The measurement is performed once.

The position holding pad 10 made of such a low rebound material may be provided with a detachable outer cover. If you provide a cover, you can also have water absorption,
Also, it can be removed and washed after use,
It is hygienic. When using such a cover, it is preferable to use a double cover. In this case, it is preferable to use a water-repellent material for the inner cover and a flexible material such as a pile material for the outer cover. By changing the material of the double cover, it is possible to prevent water from entering the inside of the block body in the case of incontinence or the like, and it is possible to give a soft touch to a portion that comes into contact with the body. In addition, if a fastener or the like is used for the outer cover, the durability may be deteriorated each time washing is performed repeatedly. Therefore, it is preferable to eliminate hard portions.

As described above, according to the body position holding pad 10 of the present embodiment, fresh air can be supplied through the gap X, and therefore, it is possible to prevent a humid environment which may cause bedsores. In addition, it is possible to prevent the sweat from accumulating in the portion of the bedsore when sweating or the like. In addition, by providing the gap X and the gap Y, it is possible to improve the air permeability in any usage, and by dropping the corner A, for example, when the caregiver sets the body position holding pad 10. It is easy to grasp and workability is improved.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment and can be variously modified. For example, a plurality of concave grooves can be provided on the slope P. If such concave grooves are provided, the sweat that has been sweated can be positively guided downward. This also gives
It is possible to prevent sweat or the like from accumulating near the affected part. In addition, the grooves allow air to circulate on the contact surface, preventing a humid environment.

In the above embodiment, the triangle ABC is a right triangle. However, the triangle is not limited to a right triangle, and may be an isosceles triangle as a basic shape. In short, any shape may be used as long as the corners are cut off so that a gap is formed in a lower portion such as the back. Further, in the above embodiment, two corners are cut off,
The portion to be cut is not limited to two places, but may be one place only on the corner B side. Furthermore, if a core material is provided inside the block body, deformation of a certain amount or more can be restricted.

[0024]

As described above, according to the body position holding pad according to the present invention, air is exchanged through the gap, so that it is effective to prevent worsening of bedsore or occurrence of new bedsore. It is. In addition, if the gap is provided in two places above and below, the air permeability can be improved in two places, and the caregiver can easily hold it when setting.

Further, if a concave groove is provided on the slope (P), it is also possible to release the sweat that has been sweated through the concave groove.
