[0001]

[Technical field to which the device belongs]

  The present invention is intended to prevent the destruction of bone protruding parts such as the back and waist of a care recipient during long-term bed rest. Occurrence of a pressure ulcer prevention device for preventing fatal skin disorders, namely pressure ulcer (bed sores) TECHNICAL FIELD The present invention relates to a pressure ulcer preventive device for preventing pressure sores in the sacral region which is said to be easy to do.

[0002]

[Prior art]

  Conventionally, as this kind of pressure ulcer prevention device, for example, a circle formed of a donut-shaped seat portion Commonly known are air mats with seats and multiple cushions filled with air. Has been. In the case of Enza, the donut shape is on the buttocks of the cared person who is lying down due to illness or injury. The seat of the patient is inserted to disperse the local pressure in the sacral region, so that pressure ulcer Is being prevented. In the case of an air mat, the back of the cared person was filled with air. A plurality of cushion portions are brought into contact with each other to prevent bed slippage on the back surface.

[0003]   However, in the case of the circular seat, the narrow area of the donut-shaped seat part allows the caregiver while lying on the bed. It will support the weight of the person and will exert local pressure. What's more, the caregiver in the bed The sacral part of the guardian falls into the center of the circle seat due to its own weight, The skin is pulled by the donut-shaped seat, causing skin displacement and pressure at the sacrum. Jijiru

[0004]   In the case of an air mat, the pressure of the air in each cushion part can be adjusted It may cause the caregiver to get out of bed. For example, if the amount of air introduced is small In the case of bed rest, the sacrum of the cared person in bed is bottomed by its own weight. Also, When a large amount of air is introduced, the repulsive force locally affects the back of the care recipient while lying on the bed. Will apply pressure to.

[0005]   In either case, it is not enough to prevent bedsores in the sacral region of the care recipient during bed rest. is there.

[0006]   Japanese Patent Publication No. 6-61354 discloses a pressure ulcer preventive device that solves these problems. The ones shown are known. This pressure ulcer prevention device is mainly composed of a two-layer structure. A plate-shaped support, a head support formed on the upper side of the support, and a head support formed on the lower side of the support Pair of chest back side support portions formed of pyramids each having a substantially right-angled triangular cross section, and the chest back side Lumbar support portion having a ridge having a substantially M-shaped cross section formed adjacent to the support portion, and the lumbar support And a laterally long flat plate-shaped buttocks support portion extending from the section.

[0007]   Both chest back support parts have a curved surface formed on the hypotenuse part of the cross section of a substantially right triangle, The curved surfaces are arranged at a predetermined interval so as to face each other. This curved surface is the spine It gradually rises from the spinal column to the side of the chest, The length of the connecting side is longer than the side forming the gap between the chest back supporting portions. Further, the spinal column is located in the gap between the back parts of the thorax.

[0008]   The lumbar support increases with increasing height from the back of the waist toward the sides of the waist. In addition, a flat end is formed in the central portion of the spine where the spinal column abuts. In addition, lumbar support The part is thicker than the chest back support to ensure strength to support the lumbar region. Is made.

[0009]   Then, the above-mentioned supporting portions of the head, back of chest, waist, and buttocks of the supine care recipient. By supporting it in a stable state by means of a protruding part that contacts the floor, that is, the head and chest The contact area with the back and buttocks is enlarged, and the pressure is distributed to each protruding part, Prevents bedsores.

[0010]

[Problems to be solved by the device]

  However, in the case of the pressure ulcer prevention device, the support is placed on the back of the cared person who lies on the side. The back of the cared person needs to be separated from the floor by a large distance to make accurate contact with the floor. It is a heavy burden for the caregiver, and the backside of the cared person on the side Therefore, it seems difficult to accurately abut the support at a position where the bed sores can be prevented.

[0011]   Furthermore, when the cared person in the lying position is returned to the supine position, There is a large head drop between the sacral area of the supine caregiver and the lumbar support. When the patient is supine, the sacral region of the supine caregiver may be displaced and compressed. There is a possibility that bed sores are likely to occur.

[0012]   Moreover, because the length of the buttocks support portion is short, the buttocks were brought into contact with the back of the cared person who lay on his / her side. If the support is misaligned, the supine caregiver's sacrum may bottom out. Conceivable.

[0013]   Therefore, in view of the above problems, the present invention easily abuts the sacrum of a cared person who lies on his / her side. Yes, when returning from the recumbent state to the supine state, the skin of the sacral region of the care recipient It is possible to suppress pulling and eliminate the bottom of the sacral region of the supine care recipient. An object of the present invention is to provide a pressure ulcer prevention tool capable of preventing bedsores.

[0014]

[Means for Solving the Problems]

  In order to solve the above-mentioned problems, the pressure ulcer prevention device of the present invention, as shown in claim 1, A pair of receiving pads that are rectangular in plan view and individually support the left and right buttocks of a supine person. A pressure ulcer prevention device including a cord, wherein the both receiving pads are made of elastic members, The length of the long side of the joint is the same as the length from the top of the ilium to the vicinity of the base of the thigh. In addition, the length of the short side has a length from the vicinity of the buttocks of the buttocks to the side of the buttocks, and further, On the upper surface of both of the receiving pads, face from the long side on the buttocks side of the buttocks to the long side on the side of the buttocks. A curved contact portion that becomes deeper as it goes is formed.

[0015]   Therefore, the length of the long sides of both receiving pads is from the upper end of the ilium (upper end of the buttocks). It has a length up to the vicinity of the base of the thigh, and the length of the short side is close to the buttocks of the buttocks. Since it has a length from the side (side end of the sacrum) to the side of the buttocks, The curved surface of the buttocks of the person (the care recipient who is lying in the bed due to illness or injury) when the upper surface is laid sideways. It is easy to come into contact with.

[0016]   In addition, on the left and right buttocks of a person who is slightly lying on the side, receiving pads from the sides of the buttocks In the vertical direction, with both receiving pads separated from both sides of the sacrum. Moreover, if the sacrum is separated from the floor, the left and right buttocks can be supported. , Both receiving pads allow the sacrum of the cared person in the bed to be positioned in the gap between the receiving pads. Since the sacrum of the cared person will be separated from the floor when it is placed, Well-ventilated, sacral area does not get stuffy or sticky due to sweating, and the circumference of the sacrum area is favorable It is kept in the boundary. Moreover, even if you are in a supine position, place a urinary device in the gap between the receiving pads. It can be easily inserted, and the caregiver's labor in urinating is greatly reduced.

[0017]   Moreover, with both receiving pads, the large size from the ilium to the buttocks and the base of the thigh A large contact area is obtained, and the buttocks are supported in a stable state. The weight of the said buttocks is evenly distributed over the entire receiving pad, Local pressure is avoided.

[0018]   In addition, the curved abutment formed on the upper surface of both receiving pads is from the buttocks side of the buttocks. Since it is formed so that it becomes deeper toward the side of the buttocks, it was supine It will fit the curved surface of the buttocks. The reason for this will be described below. Supine The left and right buttocks at the time of contact become a hemispherical bulge of the buttocks due to pressure contact with the floor due to its own weight. Pressure will be applied. At this time, the bulge of the buttocks should be spread slightly to the side of the buttocks. Will be flattened. Therefore, the curved surface of the contacting part of the receiving pad should be The shape matched to the bulge of the part, that is, from the cleft side of the buttocks to the side of the buttocks, If the curved surface of the contact part of the receiving pad is supine, It will fit the curved surface of the part. Therefore, the buttocks should be pressed against the contact part of the receiving pad. However, the repulsive force that forcibly pulls the skin of the sacral region is suppressed, No slippage, friction, or compression due to excessive pulling of the bone on the skin.

[0019]   In addition, the elasticity of the receiving pad and the contact portion of the curved surface of the receiving pad cause Pressure on the buttocks that is appropriate for the weight will be applied, and you will be forced to push up the sacrum. Soon, there is no bottom in the sacrum. For this reason, when you lie on your back Of the sacrum by all S-shaped curves, that is, the drop from the lumbar part in the sacrum is small Therefore, local pressure concentration in the sacral region is more avoided.

[0020]   As described above, the curved abutment prevents the floor slippage from acting as a circular seat or an air mat. It is something that cannot be realized with pressure ulcer prevention tools such as I can say.

[0021]   Further, as described in claim 2, the long side on the gluteal cleft side of the upper surface of the receiving pad has the length. The inner support part of the ridge is formed along the side, and the buttocks side on the upper surface of the receiving pad On the long side of the surface side, the outer support portion of the ridge is formed along the long side, and the inner support portion is called the outer support portion. It is designed to be extremely low and thin.

[0022]   In this case, the inner support part causes the vicinity of the gluteal cleft (the side end of the sacrum) and the thigh The inner surface of the base is supported and the outer support supports the upper end of the iliac (above the buttocks). End) and the outer surface of the base of the thigh will be supported, and in the supine state The buttocks can be supported in a more stable state. Moreover, from the lying position to the supine position When returned, the receiving pad fits more securely on the buttocks by the inner and outer supports. Will not be displaced from the buttocks.

[0023]   In addition, since the inner support part is lower and thinner than the outer support part, It is possible to insert it from the lateral side of the buttocks simply by placing the crab on its side, and for people in the bed. It does not force you to change your posture, and the caregiver's labor can be greatly reduced. Note that As for the position when a person lying on the bed is lying on the side, the back of the person is about 30 degrees with respect to the floor. Positions that are in position are preferred.

[0024]   Further, as described in claim 3, the receiving pad is made of a thick and soft elastic member. Consists of an upper layer part and a lower layer part consisting of a thin, hard elastic member. And the outer support portion are formed on the upper layer portion of the pad.

[0025]   Therefore, since the upper layer is soft, it easily fits the curved surface of the buttocks. As a result, a large contact area is surely obtained, and the locally applied pressure is spread over a wide range. While being dispersed, the hard lower layer prevents the bottom of the sacral region from bottoming out. The force is now applied to the buttocks, further suppressing the tension and compression of the sacral skin To be done. Here, the reason why the receiving pad has a two-layer structure will be described below. Simply sacrum If only considering the bottom of the part, push up the sacral part upward with a strong elastic force. However, if this pushing back force is strong, it will cause a bed sore, so it will be applied to the buttocks. It is necessary to disperse the pressure and then push up the sacrum from below. For that, Instead, the upper part of the receiving pad is given flexibility, and the buttocks are adjusted to some extent by its weight. Let it sink and make the upper surface of the receiving pad evenly contact the buttocks. Next, Elasticity is applied to the lower layer of the receiving pad to push up the sacrum from below. To be so In this way, the elasticity of the lower layer is applied to the buttocks via the upper layers, so the force applied to the buttocks is moderate. Will be adjusted to. Therefore, the upper part plays the role of pressure distribution in the buttocks and the lower part Will play a role as a cushioning member against the elasticity of.

[0026]   In addition, as described in claim 4, both receiving pads are individually covered with a cover, Cover both receiving pads so that they are inserted in the left and right buttocks. The belts are detachably connected by a belt-shaped connecting member.

[0027]   Therefore, by covering the receiving pad with the cover, the receiving pad is not soiled. It can be prevented. Furthermore, at the time of sale, the covers of both receiving pads were connected by a connecting member. It is displayed in a state, and when used, the receiving pad covered with the cover is separated from the connecting member. By doing so, the two receiving pads can be inserted individually from the side of the buttocks that are located on the left and right sides. Like

[0028]   Further, as described in claim 5, a fold line is formed along the longitudinal centerline of the connecting member. May be done.

[0029]   In this case, by bending from the fold line of the connecting member, the back surface of the receiving pad is joined. As it is made compact, it can be easily stored even in a narrow storage space. At the same time, it becomes easy to carry.

[0030]
