Description

[Technical Field]

[0001] The present invention relates to the prevention of bedsores and nerve paralysis and position changes for bedridden patients, and in particular to a lower limb support mat that allows for easy position changes and prevents bedsores on the fibular head, lateral malleolus, or heel, peroneal nerve paralysis, etc. It also relates to an upper limb support mat that stably supports the upper limbs during intravenous drip, dialysis, or catheter insertion, preventing bedsores from occurring in the elbows. [Background technology]

[0002] The problem of bedsores in patients in hospitals, home care stations, etc., and the repositioning and proper positioning of patients to prevent this, are important issues. In addition, how to fix or reposition patients during treatment or examinations in medical institutions, as well as how to prevent the occurrence of bedsores, has become an issue, and various proposals have been made to address these issues.

[0003] For example, Patent Document 1 proposes a supporter for preventing bedsores. Specifically, the supporter is comprised of a cylindrical cushion that is attached to the lower leg and covers the user's foot and ankle, and a cushion cover that covers the cylindrical cushion from the inner surface to the opening edges at both ends, with the cushion cover having a radially stretchable tightening section in the middle and less stretchable ends at both ends. This supporter is said to be able to prevent bedsores on the heel, ankle, and fibular head, as well as peroneal nerve paralysis, by preventing displacement of the positional relationship between the heel, ankle, ankle, lower leg, and fibular head and the orthosis, even when the user changes position or turns while lying down.

[0004] Patent Document 2 proposes a heel-supporting protective boot for bedridden patients, which includes a main body made of a flexible, compressible, convoluted, non-allergenic foam material, a foot support section that supports the patient's extended foot in an upright position, and a leg support section that supports the patient's leg in a substantially horizontal position on the bed with the patient's heel elevated above the adjacent bed surface. The boot uses a friction-reducing material in the main body under the foot and heel, allowing the boot to slide freely on the bed surface with minimal resistance, preventing bed linen from twisting, dislocation of the patient's foot within the boot, pinching the heel, or loss of support for the patient's sole. It also states that an additional foam pad can be glued to the outer surface of the boot to prevent external rotation of the leg, and a pad can also be glued to the inside of the boot adjacent to the foot support section to limit foot drop.

[0005] Patent Document 3 proposes a medical positioning mat comprising a gas-impermeable bag having a gas supply / degassing section and a cushion body formed by longitudinally connecting a plurality of gas-permeable bags made of woven or knitted fabric and filled with foam beads, the gas-permeable bags at both ends in the shorter direction being filled with foam beads having an average particle size smaller than that of the gas-permeable bags inside them, and after the patient's position is determined using the medical positioning mat before degassing, the air inside the gas-impermeable bags is degassed, thereby tightly adhering the gas-permeable bags and fixing the foam beads inside the gas-permeable bags, thereby fixing all or part of the patient's body. This medical positioning mat is characterized in that airtight permeable bags, filled with foam beads inside the gas-impermeable bag, are arranged in parallel in the longitudinal direction via connecting sections and are housed inside the airtight impermeable bag. Therefore, by venting the inside of the airtight, non-permeable bag, the patient's body can be fixed in position with the legs positioned along the connecting part without the patient feeling any "bottom contact" or "hardness," which is said to prevent bedsores and also shorten the time required to prepare for positioning. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 5552578 [Patent Document 2] U.S. Patent No. 5,449,339 [Patent Document 3] Japanese Patent Application Publication No. 2019-63416 Summary of the Invention [Problem to be solved by the invention]

[0007] The heel, lateral malleolus, and fibular head are common areas around the ankle. To prevent and minimize the occurrence of pressure ulcers in these areas, bedridden individuals must be supported with their heels elevated above the bed surface to maintain proper limb positioning and allow for easy repositioning. For example, the pressure ulcer prevention supporter described in Patent Document 1 is said to prevent pressure ulcers because it maintains the positional relationship between each support area and the orthosis even when the individual changes position or rolls over, thereby preventing the formation of pressure ulcers. However, maintaining proper limb positioning with a tubular pressure ulcer prevention supporter is not always easy. Furthermore, the heel-supporting protective boot described in Patent Document 2 maintains proper limb positioning around the foot and lower limb and is highly breathable, but it is not always easy to reposition the individual, and the heel-supporting protective boot's complex design is problematic.

[0008] The medical positioning mat described in Patent Document 3 has foam beads that move only in the longitudinal direction of the bag, not in the lateral direction. Therefore, when the air is evacuated through the airtight, impermeable bag, the patient's body and legs are fixed in position without feeling any bottoming or hardness due to the foam beads moving along the patient's body. This is desirable because the patient's position is fixed with body pressure dispersed. However, there is a problem in that a device and structure are required to evacuate the airtight, permeable bag filled with foam beads, which is not economically desirable.

[0009] In view of the problems of the prior art, the present invention aims to provide a lower limb support mat with a simple structure that allows for easy limb positioning and position change, and that suppresses and prevents bedsores on the fibular head, lateral malleolus, or heel, as well as peroneal nerve paralysis, etc. Another aim is to provide an upper limb support mat that stably supports the upper limbs during intravenous drip, dialysis, or catheter insertion, while preventing bedsores from occurring in the elbow area. [Means for solving the problem]

[0010] The lower limb support mat of the present invention comprises a mat body having a resin pipe piece as a filling, the sides of which are sewn together longitudinally to form a pair of tubular bag bodies, the entrance to which is formed by overlapping the lower edges of the two bodies being sewn together, and a window formed between the sewn parts of the sides and the sewn parts of the lower edges; and a band which clamps the sewn parts of the sides to draw the pair of tubular bag bodies together and tighten them.

[0011] In the above invention, the tubular bag body has a double structure consisting of an outer bag and an inner bag made of knitted fabric, and the inner bag has a length that is 1.3 to 1.6 times the length of the outer bag, and is preferably divided into multiple compartments of equal length in the longitudinal direction to accommodate stuffing.

[0012] The outer bag and the inner bag preferably have upper and lower edges that form the rims of the bags knitted with elastic yarn, and the boundary between the main body and the upper or lower edges is lap-stitched to form a bag shape. The main body of the outer bag preferably has a two-layer structure with a surface layer knitted with polyester nanofiber yarn and a back layer knitted with nylon fiber yarn.

[0013] . The resin pipe piece may be made of polyvinyl chloride resin, polyethylene resin, or polypropylene resin and have an outer diameter of 2 to 10 mm, a wall thickness of 0.2 to 0.4 mm, and a length of 5 to 10 mm.

[0014] The band may comprise a strip extending from the outer side of one tubular bag and a fastening portion provided on the outer side of the other tubular bag. The strip and fastening portion may respectively constitute the loop surface and hook surface of the hook-and-loop fastener, and the strip may have loop surfaces on both the front and back sides.

[0015] The method of fixing the position of a patient's lower limbs according to the present invention is a method of fixing the position of a lower limb supporting mat, in which the band of the mat is made of hook-and-loop fastener, and the mat has a band with loop surfaces on both sides extending from the outer side of one tubular bag, and a locking part with a hook surface that engages with the loop surface on the outer side of another tubular bag, by folding the mat body so that the first toe is on the side of the locking part to form a depression for holding the heel, and then arranging the patient's lower limbs along the seams on the side and inserting the heel into the depression, and engaging the band with the locking part to fix the patient's lower limbs.

[0016] The upper limb support mat of the present invention comprises a mat body having a resin pipe piece as a filling, the sides of which are sewn longitudinally to form a pair of tubular bag bodies, the entrance of which is sewn together by overlapping the lower edges of the two bodies, and a window formed between the sewn parts of the sides and the sewn parts of the lower edges; a thumb support part for holding the patient's thumb, which is provided on the outer side of the tubular bag body near the sewn parts of the lower edges; and a band for clamping the sewn parts of the sides to draw the pair of tubular bag bodies together and tighten them.

[0017] In the invention relating to the upper limb support mat, the tubular bag body has a double structure consisting of an outer bag and an inner bag made of knitted fabric, and the inner bag has a length 1.3 to 1.6 times that of the outer bag, and is preferably divided longitudinally from the lower edge into individual compartments for accommodating multiple paddings for the hand and arm areas.

[0018] The outer bag and the inner bag preferably have upper and lower edges that form the rims of the bags knitted with elastic yarn, and the boundary between the main body and the upper or lower edges is lap-stitched to form a bag shape. The main body of the outer bag preferably has a two-layer structure with a surface layer knitted with polyester nanofiber yarn and a back layer knitted with nylon fiber yarn.

[0019] In addition, it is preferable that the amount of padding contained in the hand region per unit length is 1.3 to 1.7 times that of the padding contained in the arm region. [Effects of the Invention]

[0020] The lower limb support mat according to the present invention has a simple structure and can easily maintain and change limb position to fix the body position, thereby suppressing and preventing bedsores on the fibular head, lateral malleolus or heel, peroneal nerve paralysis, etc. Furthermore, the upper limb support mat according to the present invention can stably support the upper limb during intravenous drip, dialysis or catheter insertion, while preventing the occurrence of bedsores on the elbow.

[Figure 7] FIG. 7 is a development view of the outer bag and inner bag portions that constitute the tubular bag body of FIG. 6. DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of a lower leg support mat according to the present invention is shown in FIGS. 1 to 4. As shown in FIG. 1, this lower leg support mat includes a mat main body consisting of a pair of tubular bags and a band that draws and tightens the pair of tubular bags. Specifically, this lower leg support mat 100 includes a mat main body 20, which is padded with resin pipe pieces 17 and has a pair of tubular bags 10A, 10B whose sides are sewn together in the longitudinal direction, with the opening 10b formed by overlapping the lower edges 10a (10aL, 10aR) of the tubular bags 10A, 10B. The opening 10b is formed by sewing the lower edges 10a (10aL, 10aR) together, and a window 26 is formed between the seam 21 on the side and the seam 22 on the lower edge 10a. The band 30 also includes a mat main body 20 that draws and tightens the pair of tubular bags 10A, 10B across the seam 21 on the side. The lower edges 10a are sewn together to form a recess 25 that opens into the window 26.

[0023] As shown in Fig. 2, a depression 25 is formed in the lower portion of this lower limb support mat, and this depression 25 opens into a window 26. These are formed by sewing together the entrance of the opening 10b formed by the lower edge 10aL of the tubular bag 10A and the lower edge 10aR of the tubular bag 10B, with the side seams 21 sandwiched between them, as shown in Fig. 2(b). The length of the seam 22 on the lower edge 10a is set to 1 / 4 to 1 / 2 of the total length of the lower edge 10a. An appropriate length is selected so that the seam 22 on the lower edge 10a has sufficient strength, the depression 25 is an appropriate size to accommodate the patient's heel, and the window 26 ensures appropriate breathability.

[0024] FIG. 3 shows the appearance (a) and longitudinal cross section (b) of the tubular sash 10. The lower edge 10a and upper edge 10b of the tubular sash 10 are also shown. As shown in FIG. 3, the tubular sash 10 is made of an outer bag 12 and an inner bag 11, both made of knitted fabric, which are overlap-sewn together at hem portions 121 and 111 at both ends with a lap stitch 15. The inner bag 11 has a length 1.3 to 1.6 times that of the outer bag 12, and is divided into compartments 115 of equal length in the longitudinal direction, with resin pipe pieces 17 inserted into each compartment 115. In the above, "equal length" means equal or substantially equal length, and the number of compartments is appropriately selected depending on the size of the lower leg support mat, etc.

[0025] 4 shows the inner bag 11 and outer bag 12 in an unfolded state. The inner bag 11 has a main body 110 and a rim 111, and is provided with a partition 113. In this example, this partition 113 forms two compartments 115 of equal volume, and an equal amount of resin pipe pieces 17 are inserted into each compartment 115. The tubular bag body 10 can have dimensions of, for example, a length of 300 to 500 mm, a width of 100 to 170 mm, and a thickness of 35 to 55 mm.

[0026] The main body 110 of the inner bag 11 is preferably made of a coarse knitted polyester fabric so that the lower leg support mat 100 dries easily after washing. The rim 111 is made of a knitted elastic yarn fabric and is highly stretchable. A resin pipe piece 17 is inserted into the inner bag 11. The resin pipe piece 17 has the advantage of drying quickly after washing and being easy to remove dirt.

[0027] The outer bag 12 has a main body 120 and a rim 121. The main body 120 has a two-layer structure consisting of a surface layer knitted from polyester nanofiber yarn and a back layer knitted from nylon fiber yarn. The nylon fiber yarn ensures the strength of the tubular bag 10. The polyester nanofiber yarn used for the surface layer of the knitted fabric can have a polyester nanofiber filament count of 2,000 to 60,000 and a total fineness (product of single fiber fineness and number of filaments) of 35 to 500 dtex. The polyester nanofiber is formed from a polymer such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polylactic acid, or a polyester copolymerized with a third component, and has a single fiber diameter (diameter of a single fiber) of 200 to 2,000 nm, more preferably 250 to 800 nm. Knitted fabrics made from polyester nanofiber yarn have high friction resistance, making them non-slip and providing excellent grip. This makes it easy to ensure and maintain a proper, stable posture. It also has excellent water-holding properties, absorbing moisture, sweat, dirt, and the like in an appropriate amount.

[0028] The resin pipe piece 17 can be formed in a single shape. The resin pipe piece 17 can be made of polyvinyl chloride resin, polyethylene resin, or polypropylene resin, and has an outer diameter of 2 to 10 mm, a wall thickness of 0.2 to 0.4 mm, and a length of 5 to 10 mm. The resin pipe piece 17 can be prepared by cutting a resin pipe to a predetermined size. Polyethylene resin pipe is made of high-density polyethylene (HDPE) resin or low-density polyethylene (LDPE) resin, and resin pipe pieces 17 with different elasticity or hardness can be obtained. The resin pipe piece 17 of the present tubular bag 10 has appropriate elasticity and fluidity, which allows for the alleviation of shear force and the distribution of body pressure. For this reason, it is important to select the resin pipe piece 17 with appropriate elasticity, size, and filling amount (amount inserted into the compartment 115 in g / cm 3 ). 3 ) is selected.

[0029] As described above, the tubular bag 10 has an inner bag 11 1.3 to 1.6 times longer than the outer bag 12, and the resin pipe pieces 17 are inserted into the compartments 115, which are divided into equal longitudinal lengths. This allows the inner bag 11 to deform freely in response to the applied pressure, and the resin pipe pieces 17 flow and displace somewhat freely depending on the deformed shape of the inner bag 11. Meanwhile, the highly elastic rims 111, 121 of the tubular bag 10 limit the deformation of the tubular bag 10 to a certain range. If the length of the inner bag 11 is shorter than 1.3 times the length of the outer bag 12, the flowability of the resin pipe pieces 17 is restricted, making it difficult to achieve the intended shear force relief and body pressure distribution effects. If the length of the inner bag 11 is longer than 1.6 times the length of the outer bag 12, the resin pipe pieces 17 are more likely to become misaligned.

[0030] The band 30 functions to draw and tighten the pair of tubular bags 10A, 10B together by sandwiching the side seams 21. As shown in FIG. 1, the band 30 may comprise a strap 31 extending from the outer side 23 of one tubular bag 10B and a fastening portion 32 provided on the outer side 23 of the other tubular bag 10B. The strap 31 and fastening portion 32 may respectively constitute the loop and hook surfaces of a hook-and-loop fastener. Taking into consideration the method of fixing the patient's position, as described below, the strap 31 preferably has loop surfaces on both the front and back. Furthermore, the strap 31 is preferably wide to widen the engagement area with the fastening portion 32. The outer side 23 of the tubular bag 10B refers to the side opposite the side seams 21 (inner side).

[0031] The method for using the lower limb support mat 100 to hold a patient in an appropriate position and fix the position is as follows: First, the patient's lower limbs are positioned along the seams 21 on the sides of the mat body 20, with the heels housed in the recesses 25. The appropriate position is then maintained, and the pair of tubular bags 10A, 10B are pulled together and tightened with the bands 30 to fix the position. At this time, it is preferable to tighten the bands 30 in a direction that prevents the patient's lower limbs from externally rotating. That is, if the patient's first toe is positioned on the side of the locking portion 32, the tightening force of the straps 31 of the bands 30 acts in a direction that prevents the patient's lower limbs from externally rotating.

[0032] According to the above-described method for fixing a patient's position, the lower limb support mat 100 can preferably be used for both left and right lower limbs. Therefore, the strap 31 and the fastening portion 32 are preferably attached to the center of the outer side portion 23 of the tubular bag 10, with the loop surfaces of the strap 31 provided on the front and back sides. As shown in FIG. 1 or FIG. 5, the mat body 20 can be used for either the left or right lower limb by folding back the mat body 20 from the side seam 21. Furthermore, the wide joint area between the strap 31 and the fastening portion 32 allows for appropriate limb positioning. Furthermore, the lower limb support mat 100 can stably support the patient's lower limbs by surrounding them with the pair of tubular bags 10A, 10B, and can stably support the patient on a floor surface such as a bed. In particular, the surface layer of the tubular bag 10 is knitted from polyester nanofiber yarn, which has excellent grip, allowing for stable support of the patient.

[0033] The above describes the lower limb support mat according to the present invention. The structure and technical concept of this lower limb support mat can be applied as is to an upper limb support mat. However, in an upper limb support mat, it is important to hold the thumb in a predetermined position in order to properly support the upper limb. The upper limb support mat according to the present invention has a configuration similar to that of the lower limb support mat described above, as shown in FIG. 6 . The upper limb support mat 101 is characterized by having a thumb support portion 35 on the outer side portion 23 of the tubular bag 10 near the seam 22 at the lower edge of the tubular bag 10. The thumb support portion 35 is positioned so that the patient's upper limb is positioned along the seam 21 on the side of the mat body 20, and when the patient's fingertips protrude from the window portion 26, the thumb is supported by the thumb support portion 35. Like the lower limb support mat 100, this upper limb support mat 101 can be used for both left and right upper limbs.

[0034] Furthermore, during intravenous drip infusion, dialysis, or catheter insertion, patients are not only restrained for long periods of time, but are also required to maintain a specific posture. In such cases, if the patient's hands are held in a wrapped-around position, the patient will feel more secure and more likely to maintain a specific posture. Furthermore, the ends of the tubular bag generally tend to have less padding. Therefore, to ensure stable support of the patient's hands, it is recommended to provide a hand section that can support the patient's hands from the wrists onward in a bulging, wrapped-around manner when the patient's fingertips protrude from the window of the mat body. It is also recommended to provide an arm section following the hand section to prevent bedsores, which are prone to develop around the elbows. The amount of padding contained in the hand section should be 1.3 to 1.7 times the amount of padding per unit length contained in the arm section.

[0035] The main body of the outer bag constituting the tubular bag of this upper limb support mat preferably has a two-layer structure with a surface layer knitted from polyester nanofiber yarn and a back layer knitted from nylon fiber yarn, similar to the lower limb support mat. The knitted fabric made of polyester nanofiber yarn has high friction resistance, making it non-slip and has excellent grip, allowing it to stably support the patient's upper limbs.

[0036] Furthermore, upper limbs tend to move easily due to rotation and bending of the hands and upper arms. Therefore, it is preferable that the main body of the band constituting the band has both front and back surface layers knitted from polyester nanofiber yarn. The band can stably support the patient's upper limbs by drawing and tightening the pair of tubular bags together, sandwiching the seams at the sides. Figure 6 shows the main body 30a of the band 31 of the band 30. As shown in the development view (Figure 7) of the outer bag 11 and inner bag 12 constituting the tubular bag 10 of the upper limb support mat 101, a hand section 116 and an arm section 117 are formed by a partition 113. The partition 113 is provided in the area corresponding to the wrist. [Explanation of symbols]
