  In recent years, if a person who has difficulty in moving the body, such as a sick person or a disabled person, maintains the same posture such as bedridden for a long time, a part of the body is pressed against clothing or bedding for a long time, and this pressure site There may be gangrene called pressure ulcers or bedsores. Therapeutic devices that improve such pressure sores are being considered. For example:

WO2004 / 037149 Japanese Unexamined Patent Publication No. 7-313585 JP 2008-110096 A JP 2005-179697 A Japanese Patent Laid-Open No. 2003-319977 JP 2007-270394 A JP-A-2005-179808 JP 2004-107800 A

  The present invention has been made to solve the above-described problems, and an object of the present invention is to improve pressure ulcers such as preventing or treating such pressure ulcers with a simple improvement tool. .

  In order to achieve the above object, a pressure ulcer improving tool of the present invention comprises a main body made of a material having elasticity, and two outer surfaces of the main body, the two surfaces having the largest area, with respect to one surface. And at least two surfaces with the other surface inclined, and a plurality of recessed grooves formed on the two surfaces for maintaining ventilation and light transmission, and provided at substantially the same position on the front and back of the two surfaces. A concave groove having a substantially constant distance between the bottoms of the concave grooves despite being substantially along or inclined along the inclined direction of the two surfaces.

  By this, the pressure ulcer improvement tool is inclined, so it is inserted between the back of a person who has difficulty in moving the body such as a sick person or a disabled person (hereinafter referred to as “sick person”) and a futon, It is possible to change the body orientation to the right inclination for the sick person, etc. so that pressure ulcer does not occur, can be prevented / prevented, does not get worse or can be treated (hereinafter referred to as “improvement of pressure ulcer”).

  Changing the direction of a sick person from the back to the side causes high pressure on parts of the body such as the shoulders and pelvis, causing new pressure ulcers. In order to prevent this, the inclination of the recumbent position is 5 ° to 45 °, preferably 7.5 ° to 30 °, more preferably 9 ° to 15 °, and this pressure is improved by the pressure ulcer improving tool of the present invention. Can be achieved. In addition, air permeability is maintained in the concave groove, so that generation of pressure ulcers or deterioration / expansion of pressure ulcers is prevented.

  Furthermore, since the concave groove becomes deep at the thick part of the pressure sore improving tool and the main body, even if the human body comes into contact with this part, the concave groove is not blocked, and the breathability of the pressure sore improving tool and the main body, The light transmission property and the moisture-releasing property are maintained.

(1) Structure of pressure sore improvement tool 10 FIGS. 1-4 shows the external appearance and cross section of a pressure sore improvement tool. The main body 1 constituting the inside of the pressure sore improving tool 10 is made of a material having cushioning properties, foaming properties, stretchability, elasticity or / and flexibility, such as urethane foam and sponge. The main body 1 has a shape in which a triangular prism is turned sideways, and a cross section is a right triangle. A surface along the longer side of the two sides sandwiching the right angle of the right triangle (hereinafter referred to as “base”) is referred to as a bottom surface 2. A plane along the hypotenuse that is the opposite side of the right angle is referred to as a hypotenuse plane 3.

  These two surfaces of the bottom surface 2 and the oblique surface 3 are the two surfaces having the largest area among the outer surfaces of the main body 1, and the other surface is inclined with respect to one surface. The inclination angle of the bottom side surface 2 and the oblique side surface 3, that is, the two surfaces having the largest area is 10 degrees in the absence of a load. However, depending on circumstances, it may be 5 ° to 45 °, preferably 7.5 ° to 30 °, more preferably 9 ° to 15 °.

  A plurality of the pressure ulcer improving tools 10 can be laminated so that the inclination is increased, and the increased inclination angle is approximately 20 degrees, approximately 30 degrees, approximately 40 degrees, and so on. . A portion corresponding to an angle between the bottom surface 2 and the oblique surface 3 is cut out and flattened, and the width of the flat corner portion is about 5 to 20 mm. The shortest side of the right triangle is called the short side surface 4. The short side surface 4 has a width of about 50 to 100 mm.

  The surface of the main body 1 is coated with apatite photocatalyst paint (photocatalyst titanium apatite, fluorinated apatite-coated titanium oxide, etc.) and has antibacterial action (including sterilization, sterilization, sterilization, and sterilization) and photocatalytic action. This application is performed with a spray gun, a roller brush or the like. The apatite photocatalyst can adsorb and remove smaller viruses, microorganisms, germs such as enterotoxin than conventional photocatalytic materials such as titanium dioxide.

  Since the main body 1 has foaming properties such as urethane foam and sponge, the surface has very fine irregularities, and the apatite photocatalyst paint is evenly applied to the irregularities, and the irregularities are not filled. The viscosity, density, and gel time until solidification in this case are as follows.

  In this case, the density (= specific gravity) of the apatite photocatalyst paint is 1.00 to 1.20 g / ml, preferably 1.08 to 1.14 g / ml, more preferably 1.10 to 1.12. 1.0 to 9.0 dPa · S, desirably 1.5 to 6.0 dPa · S, more desirably 2.0 to 4.5 dPa · S, and fluctuation degree is desirably 3.5 to 10.0. Is 4.5 to 8.5, more preferably 5.0 to 7.0, the acid value is 10 to 25 mg KOH / g, preferably 12 to 20 mg KOH / g, and the gel time, which is the time to solidify, is 10 -50 minutes, desirably 15-40 minutes, more desirably 20-30 minutes.

  When applied using an air gun, the viscosity of the apatite photocatalyst paint is 3 to 24 poise, preferably 6 to 15 poise, more preferably 9 to 12 poise, and the variation is 3.5 to 9.5. Desirably, it is 4.5 to 8.0, more desirably 5.0 to 6.5, and the gel time which is the time until solidification is 10 to 50 minutes, desirably 15 to 40 minutes, more desirably 20 to 30 minutes.

  The viscosity of the apatite photocatalyst paint when applied by brush coating or roller coating is 9 to 33 poise, preferably 15 to 24 poise, more preferably 18 to 21 poise, and the variation is 4.0 to 10.0. Yes, preferably from 5.0 to 8.5, more preferably from 5.5 to 7.0, and the gel time to solidify is from 10 to 50 minutes, preferably from 15 to 40 minutes, more preferably 20-30 minutes.

  In this way, when the apatite photocatalyst paint is applied evenly on the fine unevenness of the surface of the main body 1 without being unevenly filled, the surface area where the apatite photocatalyst is exposed to the air / outside air is greatly increased, causing germs Adsorbs and removes pressure ulcers such as microorganisms and viruses.

  The main body 1 is accommodated in an outer cloth 5 woven in a bag shape along the outer surface of the right-angled triangular columnar main body 1, and the surface of the main body 1 is covered with the outer cloth 5. The outer cloth 5 is a cloth that maintains ventilation with a pile.

  A fastener 6 is provided along the longitudinal direction at the center of the outer fabric 5 on the short side surface 4 side. The main body 1 is put in the outer cloth 5 by opening the fastener 6. A rectangular rubber cover 7 is sewn outside the position where the fastener 6 is closed. The hook 8 of the fastener 6 is housed inside the rubber cover 7, and it does not hurt even if the hook 8 hits the human body.

  The material of the outer fabric 5 is made of bamboo fiber (bamboo fiber) made from bamboo, antibacterial, deodorant, moisture absorption (moisture absorption), humidity adjustment (automatic adjustment of humidity / humidity), moisture release (moisture discharge) ), Far infrared rays are generated, and static electricity is hardly generated. Bamboo fibers are also excellent in gloss, color development and heat radiation. Furthermore, bamboo fiber is excellent in dyeability and color developability, and is comfortable to wear.

  The humidity control action is an action that discharges moisture to the outside when the inside humidity rises and absorbs the humidity of the outside air when the inside humidity falls, and keeps the inside humidity constant. A large number of piles are formed on the outer surface / surface of the outer fabric 5 and are woven so that there are sufficient gaps, and are filled with piles like a towel, so that the breathability and moisture absorption are excellent. .

  The main body 1 covered with the outer cloth 5 is sewn in a straight line with a thread from the oblique side 3 to the bottom side 2 and is recessed at substantially the same position on the front and back of the two sides of the oblique side 3 and the bottom side 2. A groove 11 is formed. A plurality of the concave grooves 11 are formed in parallel so as to cross the rectangular oblique side surface 3 and the bottom side surface 2 at right angles.

  Both bottoms of the concave groove 11 are sewn together in a quilting manner with a thread, with the front and back sides being substantially equidistant from each other. In other words, the distance between the front and back of both bottoms of the concave groove 11 is substantially constant regardless of whether the two surfaces are substantially along or obliquely inclined. Since this concave groove 11 creates a gap between the human body and the surface of the present pressure ulcer improving tool 10, the moisture release effect of the outer cloth 5 is not exhibited and does not decrease, and pressure ulcer is improved by this moisture release.

  In other words, the distance between the both concave grooves 11 on the front and back of the hypotenuse surface 3 and the bottom side surface 2 is large even in the thick part close to the short side surface 4 of the pressure sore improving tool 10 and the main body 1 or in the thin part opposite to the short side surface 4. It becomes almost constant. Further, the concave groove 11 is deep at a thick part near the pressure sore improvement tool 10 and the short side surface 4 of the main body 1, and the concave groove 11 is shallow at a thin part opposite to the short side surface 4.

  Thus, since the concave groove 11 becomes deep in the thick part near the pressure sore improvement tool 10 and the short side surface 4 of the main body 1, the concave groove 11 is blocked even if a human body comes into contact with this part. The air permeability and the moisture releasing property are maintained. At the bottom of the groove 11, the thread is sewn into an elongated rectangular shape, the width of the groove 11 is increased, and the width of the groove 11 is increased, thereby improving air permeability and moisture release.

  The concave groove 11 is concave and has a certain width at the bottom of the concave groove 11, so that air permeability and moisture releasing properties are maintained, and light transmittance is also maintained. Due to this light transmittance, the photocatalytic action of the main body 1 is exhibited. In this case, the outer cloth 5 covering the main body 1 is mesh-like and translucent even if there is a pile, and the photocatalytic action of the main body 1 does not deteriorate.

  In addition to the parallel grooves, the concave grooves 11 may be formed with further concave grooves 11 that intersect the concave grooves 11 diagonally or at right angles. Even in this case, the distance between the front and back of both bottoms of the groove 11 is substantially constant. As a result, the distance between the front and back of both bottoms of the groove 11 is substantially constant despite the fact that the two sides of the oblique side surface 3 and the bottom side surface 2 are obliquely along the inclination direction.

  The concave groove 11 does not reach the peripheral edge and the short side surface 4 of the pressure sore improving tool 10 and the main body 1, and the concave groove 11 is not formed along the outer peripheral edge of the pressure sore improving tool 10 and the main body 1. Thereby, the depression by the human body contact | abutting of the pressure ulcer improvement tool 10 and the outer periphery of the main body 1 which the contact pressure of a human body tends to become large can be reduced.

  FIGS. 5-6 shows the use condition of the pressure sore improvement tool 10. FIG. A plurality of, for example, three of the pressure ulcer improving tools 10 are laminated so that the inclination is increased, and the increased inclination angle is set to approximately 30 degrees, and is directly applied to a head, a shoulder, a back, a waist, a hip, a thigh, a lower leg, and the like. Or inserted under a futon or mattress. Thereby, a sick person etc. can change the direction of a body to the just right inclination which can improve pressure ulcer.

  Changing the direction of a sick person from the back to the side causes high pressure on the shoulders and pelvis, causing new pressure ulcers. The above 30 degrees is just right. This angle of 30 degrees may be 20 degrees or 10 degrees. Also, it may be 5 to 45 degrees, preferably 7.5 to 30 degrees, more preferably 9 to 15 degrees.

  When a predetermined time has elapsed, the pressure ulcer improving tool 10 is pulled out and inserted on the opposite side. Thereby, a sick person does not remain in the same posture for a long time, a part of the body is not pressed for a long time, and prevention or treatment of pressure ulcers (bed slippage) can be improved.

  Such a pressure sore improving tool 10 may be inserted into both the left and right instead of alternating between left and right as described above. Thereby, the central part of a sick person or the like is not compressed for a long time, and prevention or treatment of pressure ulcer (bed slippage) in the central part can be improved.

  Such a pressure sore improvement tool 10 can be sandwiched between the human body of a person sitting in a wheelchair and the wheelchair, for example, between the back and back of the waist, the back, the back and back of the buttocks, and the side and bottom of the thigh. . In the above case, if the number of pressure ulcer improving tools 10 to be stacked is increased or decreased, the inclination angle of the pressure ulcer improving tools 10 to be stacked can be arbitrarily changed, and an optimal inclination that can improve pressure ulcers can be realized.

(2) Second Embodiment FIGS. 7 to 8 show a second embodiment. A belt-like connecting string 12 (fixing tool) made of cloth is stitched and connected along both end edges along the longitudinal direction of the short side surface 4, and both ends of the connecting string 12 are connected to the short side surface 4. It is stitched at both corners of both edges.

  When these two connecting strings 12, 12 are connected to each other, the pressure sore improving tool 10 is fixed in a state of being curved in a substantially cylindrical shape. In this case, the short side surface 4 forms a part of the upper surface or the lower surface of the cylinder in an annular shape, and the thickness of the curved cylinder gradually becomes thinner, thinner, thicker, or thicker in a tapered shape.

  Such a pressure sore improvement tool 10 curved and fixed in a cylindrical shape is wound around the extremities such as the upper arm, the forearm, the entire arm, the thigh, the lower leg, and the entire leg. As a result, cold protection, warming, warming, blood circulation promotion, antibacterial action, photocatalytic action, breathability, moisture release, and pressure ulcer improvement of the limbs can be achieved.

  In this wrapping, if the thick short side surface 4 is positioned closer to the hand or foot, blood circulation of the hand or foot that tends to deteriorate blood circulation can be promoted. In addition, in this winding, when the thick short side surface 4 side is positioned closer to the hand or foot, the side closer to the torso of the limbs is lifted from the upper surface of the futon to prevent blood pressure and improve blood circulation. It prevents high pressure from being applied to places close to the torso and prevents pressure ulcers.

  Only one of the ends of the connecting string 12 (fixing tool) may be sewn to the corners of the short side surface 4. Even if both ends are sewn, if the length of the connecting string 12 is sufficient, the connecting strings 12 can be tied together.

(3) Third Embodiment FIGS. 9 to 10 show a third embodiment. In this embodiment, the three pressure sore improvement tools 10 are connected and can be folded and stretched. The apex corner edges formed by the bottom surface 2 and the hypotenuse surface 3 of the two pressure sore improvement tools 10 are connected by stitching or the like. The right side edge formed by the short side surface 4 and the bottom side surface 2 of one pressure sore improvement tool 10 and the right side edges of the other pressure sore improvement tool 10 of the two connected pressure sore improvement tools 10 are stitched together. Connected by

  As described above, the present pressure ulcer improving tool 10 is connected to a plurality of portions other than the inclined side surface 3 that is inclined with respect to the largest area, and can be folded together. When such a connected pressure sore improvement tool 10 is deployed and stretched, moderate unevenness is formed, and it fits in the vicinity of the back of the head, back, waist and thighs, and high pressure is applied to a part on the back side of the body. Can prevent pressure sores.

  Further, when the three connected pressure ulcer improving tools 10 are folded, a plurality of layers are stacked so that the inclination is increased, and the increased inclination angle is approximately 30 degrees. The folded pressure sore improvement tool 10 is inserted directly under the head, shoulders, back, waist, hips, thighs, lower thighs, etc. or under the futon or mattress as described above. Thereby, it is possible to prevent or improve pressure ulcers by changing the body direction to the right slope for a sick person or the like that can improve pressure ulcers.

(4) Fourth Embodiment FIGS. 11 to 12 show a fourth embodiment. In this embodiment, a plate-shaped three-dimensional knitted fabric 16 is sandwiched between the main body 1 and the outer cloth 5. The three-dimensional knitted fabric 16 has a structure in which the gap is not clogged so much and does not bend even when pressure is applied even though the gap is large.

  The three-dimensional knitted fabric 16 is harder and more flexible than the main body 1 made of urethane or the like, has a higher porosity than the main body 1, has more gaps, and is thinner than the main body 1. Further, the three-dimensional structure knitted fabric 16 is harder than the outer cloth 5, is hard to bend, has a higher porosity than the outer cloth 5, has more gaps, and is thicker than the outer cloth 5.

  As described above, the three-dimensional structure knitted fabric 16 is harder and more flexible than the main body 1 made of urethane or the like, and has a higher porosity and more gaps than the main body 1, so that even if the human body comes into contact and the main body 1 is bent and compressed. Since the compression / deflection of the three-dimensional knitted fabric 16 is smaller than that of the main body 1, a gap is maintained between the pressure ulcer improving tool 10 and the human body in contact with the pressure ulcer, air permeability and moisture release are maintained, and pressure ulcer is prevented.

  Such a structure of the three-dimensional knitted fabric 16 is shown in Japanese Patent Application Laid-Open Nos. 2007-270394, 2005-179808, and 2004-107800. What is described in these publications is also described in the detailed description of the present invention.

  Such a three-dimensional knitted fabric 16 includes front and back two layers of knitted fabrics 17 and 17 and filaments 18 connecting the two layers of knitted fabrics 17 and 17. The two knitted fabrics 17 and 17 of the front and back are knitted into a hexagonal aggregate honeycomb structure, a triangular aggregate structure, a quadrangular grid structure, and the like.

  The filaments 18 are knitted so as to connect and roughen the two layers of the knitted fabrics 17, 17. This filament 18 is made up of “X-shape”, “V-shape”, “reverse V-shape”, “M-shape”, “N-shape”, “W-shape”, “K-shape”, “Y-shape”, “A-shape”. ”,“ Reverse A shape ”,“ □ shape ”,“ state with X in □ ”,“ I shape (multiple parallel filaments 18) ”, etc. The structure is difficult to do.

  The filaments 18 having such a structure may be in the X shape or the like, or the filaments 18 are not connected but separated and independent, but may be connected. In the example of FIG. 12, the filament 18 has an “X-shaped” example. Thereby, as mentioned above, the three-dimensional structure knitted fabric 16 is harder than the main body 1 and is difficult to bend, and even if the human body comes into contact and the main body 1 is bent and compressed, the gap is maintained, and air permeability and moisture release are maintained. Pressure sores are prevented.

  Moreover, the spacing / gap between the filaments 18 is several times to several tens of times, sometimes several times to several tens of times, and sometimes several times to several tens of times as large as the thickness of the filaments 18. Thereby, as described above, the three-dimensional structure knitted fabric 16 has a higher porosity and more gaps than the main body 1, and even if the human body abuts and the main body 1 is bent and compressed, the gap is maintained, and air permeability and Moisture release is maintained.

  Such a three-dimensional knitted fabric 16 is laminated between the main body 1 and the outer fabric 5 over the bottom side surface 2 and the oblique side surface 3. Since the bottom side surface 2 and the oblique side surface 3 are provided with a concave groove 11, even if a human body comes into contact with the concave groove 11, the concave groove 11 is not further blocked, and air permeability and moisture release are provided. It is kept and pressure ulcers are prevented.

  Such a three-dimensional structure knitted fabric 16 may be laminated on the short side surface 4 or may be laminated on the side surfaces 13 and 13. Thereby, breathability and moisture release property improve more and pressure ulcer is prevented more. Further, the three-dimensional structure knitted fabric 16 may be laminated only in the vicinity of the concave groove 11, or may be laminated only on a part of the bottom surface 2, the oblique side surface 3, the short side surface 4, and the side surfaces 13 and 13. Further, the three-dimensional structure knitted fabric 16 may not be provided on the bottom side surface 2 or may be absent on the oblique side surface 3. Thereby, the three-dimensional structure knitted fabric 16 can be saved.

  Such a three-dimensional structure knitted fabric 16 may be laminated on the outer side of the outer fabric 5. Thereby, air permeability and moisture release improve and pressure sores are prevented. Moreover, a part or all of the outer cloth 5 may be omitted. Thereby, the outer cloth 5 can be saved. In this case, the three-dimensional knitted fabric 16 has the same antibacterial, deodorant, moisture absorption (moisture absorption), humidity adjustment (automatic adjustment of humidity / humidity), moisture release (humidity discharge), generation of far infrared rays, static electricity. Ingredients having such properties as being less likely to occur may be blended.

  When the outer fabric 5 is omitted, the three-dimensional structure knitted fabric 16 has a high porosity and a large number of gaps as described above. Therefore, the light projecting property is much higher than that of the main body 1, and a photocatalytic component is applied to the surface of the main body 1. Therefore, this photocatalytic action is improved.

  The three-dimensional knitted fabric 16, the main body 1, and the outer fabric 5 may be partially or entirely formed of a plurality of layers, and these may be laminated in order. Thereby, breathability and moisture release property improve more and pressure ulcer is prevented more.

  In the second embodiment of FIG. 8, when the above-described three-dimensional knitted fabric 16 is laminated, the three-dimensional knitted fabric 16 maintains air permeability and moisture release inside the tubular pressure ulcer improving tool 10, and prevents pressure ulcers. Is done.

  In the third embodiment of FIG. 10, when the above-described three-dimensional structure knitted fabric 16 is laminated, the three-dimensional structure knitted fabric 16 is more difficult to bend than the main body 1. The angle of inclination formed by the pressure ulcer improving tool 10 is maintained, and pressure ulcer can be further prevented.

As a result, pressure ulcers can be improved by suppressing the generation and proliferation of bacteria that cause pressure ulcers.

[8] The pressure ulcer improving tool according to claim 3, wherein a plurality of the pressure ulcer improving tools are connected to each other at locations other than the inclined surfaces having the largest area and can be folded together. Thereby, the connected pressure ulcer improvement tool can be folded and laminated, or expanded and stretched, and various forms can be changed according to the state and location of the sick.

[9] The pressure ulcer improving device includes a fixing device that is fixed in a substantially cylindrical shape, and is wound around the extremity in a state where the thickness of the pressure ulcer is gradually changed and the thickness is gradually changed. The pressure ulcer improving tool according to claim 1. Thereby, the blood circulation of the hand or the leg which tends to deteriorate blood circulation can be promoted. In addition, the side closer to the torso of the limbs can be lifted from the upper surface of the futon to prevent blood pressure and improve blood circulation, and prevent high pressure from being applied to places close to the torso, thereby preventing pressure ulcers.

  Breathability and moisture release are maintained, high pressure is not applied to the shoulders and pelvis, and pressure ulcers can be prevented. The pressure ulcer improving tool has a right triangular prism shape, and a concave groove 11 is formed by stitching from the front and back surfaces at approximately the same position on the front and back surfaces of the two large surfaces of the triangular prism shape. The distance between the front and back of both bottoms of the groove 11 is substantially constant despite being substantially along the inclination direction or along the oblique direction.

  Since the concave groove 11 becomes deep at the thick part near the pressure sore improvement tool and the short side surface 4 of the main body 1, the concave groove 11 is not blocked even if a human body comes into contact with this portion, and the air permeability is improved. And moisture release is maintained and pressure ulcer is prevented. In addition, because of the triangular prism shape, when placed under a sick person or the like, it is not lying on its back and is not beside it, so it can be kept in a proper posture, high pressure is not applied to the shoulders and pelvis, and pressure ulcer is prevented.
