Summary of the Invention

Problems to be Solved by the Invention

[0004] A method of inserting a body position adjuster under a mattress to change the body position of a patient is known. Since the body position adjuster described in Patent Document 1 has a simple wedge shape, there is a risk of giving the patient a sense of discomfort. Further, as an indirect method, when the body position adjuster is inserted under the mattress and used, depending on the shape and size of the body position adjuster, the body position of the patient will be greatly changed. Then, a large body pressure change will occur in the patient, and there is a risk of displacement in the patient.

[0005] Aspects of the present invention provide a body position adjuster inserted under a comfortable mattress and a sheet for the body position adjuster.

Means for Solving the Problems

[0006] An aspect of the present invention is a body position adjuster inserted under a mattress, comprising an upper surface portion, a first inclined portion extending obliquely downward from the front end of the upper surface portion, a second inclined portion extending obliquely downward from the left end of the upper surface portion, and a third inclined portion extending obliquely downward from the right end of the upper surface portion. Effect of the Invention

[0007] Aspects of the present invention can provide a user-friendly positioning device and a sheet for a positioning device that can be inserted under a mattress. [Brief description of the drawings]

FIG. 5 is a side view showing a state where a sheet for the body position adjuster is attached to the mattress. FIG. 6 is an explanatory view showing a state where the body position adjuster is inserted under the mattress. FIG. 7 is a plan view showing the sheet for the body position adjuster.

[0010] The body position adjuster 10 is for converting the body position of the patient 300 and suppressing the occurrence of bedsores on the patient 300. As shown in FIG. 6, the body position adjuster 10 is inserted between the mattress 100 and the bottom 210 (bottom part) of the bed 200. As shown in FIG. 1, the body position adjuster 10 will be described with the insertion direction into the mattress 100 as "front" and the opposite side as "rear". Also, the body position adjuster 10 will be described as "left", "right", "up", and "down" when viewed from a person facing forward.

[0011] The body position adjuster 10 is, for example, a cushion made of urethane, polyester, or the like. The body position adjuster 10 includes a bottom surface portion 11, a front surface portion 12 extending upward from the front end of the bottom surface portion 11, a left side surface portion 13 and a right side surface portion 14 extending upward from both left and right ends of the bottom surface portion 11, a rear surface portion 15 extending upward from the rear end of the bottom surface portion 11, a first inclined portion 16 extending obliquely upward rearward from the upper end of the front surface portion 12, a second inclined portion 17 extending obliquely upward rightward from the upper end of the left side surface portion 13, a third inclined portion 18 extending obliquely upward leftward from the upper end of the right side surface portion 14, and an upper surface portion 19 connecting the upper ends of the rear surface portion 15, the upper end of the first inclined portion 16, the upper end of the second inclined portion 17, and the upper end of the third inclined portion 18.

[0012] In order to suppress bedsores on the patient 300, the body position adjuster needs to perform an optimal body position conversion on the patient 300. Also, since the body position adjuster forcibly performs the body position conversion of the patient 300, the comfort of the patient 300 is also important. Furthermore, since the body position adjuster is inserted under the patient 300, it is also important that it is convenient for the caregiver to use.

[0013] In order to meet such conditions, manufacturing a dedicated body position adjuster according to the body shape of each patient 300 is costly, and since the body position adjuster must be managed for each patient 300, there is a risk that the usability will deteriorate. Therefore, a body position adjuster that can be comfortably used by a plurality of patients 300 and has good usability is desired.

[0014] Therefore, various body position adjusters with different shapes, sizes, and hardnesses were prototyped and subjectively evaluated when used by a plurality of patients. The subjective evaluation was conducted by preparing body position adjusters with different presence or absence, angles, hardnesses, and maximum thicknesses of the inclined portions of the body position adjuster. The subjective evaluation was ranked based on the comfort, displacement, muscle tension, and ease of placement when using these body position adjusters.

[0015] As a result of the subjective evaluation, the body position adjuster 10 of the present embodiment has an optimal shape, size, and hardness for a plurality of patients 300 and is also user-friendly for caregivers. Hereinafter, the shape, size, and hardness of the body position adjuster 10 will be described.

[0016] The bottom surface portion 11 is a flat surface and contacts the bottom 210 of the bed 200. The body position adjuster 10 has a front surface portion 12, a left side surface portion 13, and a right side surface portion 14 under the first to third inclined portions 16 to 18, respectively. Here, for example, when the front surface portion 12, the left side surface portion 13, and the right side surface portion 14 are not present, the lower ends of the first to third inclined portions 16 to 18 may rub against the mattress 100 or the bottom 210 of the bed 200, and the lower ends of the first to third inclined portions 16 to 18 may be easily damaged.

[0017] Therefore, the body position adjuster 10 has a thickness formed by the front surface portion 12, the left side surface portion 13, and the right side surface portion 14, thereby improving the strength. The height dimension H1 of the front surface portion 12, the left side surface portion 13, and the right side surface portion 14 is 25 mm or less (for example, 13 mm). In addition, the body position adjuster 10 may reinforce the portion located on the side opposite to the patient, such as by hardening the urethane material of the portion surrounded by the front surface portion 12, the left side surface portion 13, and the right side surface portion 14. Note that the body position adjuster 10 does not necessarily have a thickness formed by the front surface portion 12, the left side surface portion 13, and the right side surface portion 14. That is, the height dimension H1 may be 0.

[0018] The overall height H2 (vertical length) of the body position adjuster 10 is a height considering the comfort and usability of the patient 300. The height dimension H2 from the bottom surface portion 11 to the upper surface portion 19 of the body position adjuster 10 is 20 mm or more and 80 mm or less (for example, 40 mm). Thereby, since the body position adjuster 10 does not become thicker than necessary, it is possible to prevent the occurrence of pressure sores in the patient 300 and suppress the discomfort of the patient 300. In addition, since the body position adjuster 10 is overall thin, it is easy to carry. Therefore, the body position adjuster 10 can improve the usability such as taking in and out under the mattress 100 and carrying.

[0019] The width length L1 of the body position adjuster 10 (the length from the lower end of the second inclined portion 17 to the lower end of the third inclined portion 18) determines which part of the patient 300's body from the head to the toes is supported. The width length L1 of the body position adjuster 10 corresponds to the heights of a plurality of patients 300 and is a length considering the comfort and usability of the patient 300. The width length L1 of the body position adjuster 10 is 400 mm or more and 700 mm or less (for example, 500 mm).

[0020] As a result, when the body position adjuster 10 is inserted into, for example, the upper body of the patient 300, it can support the patient 300 from the scapula to the greater trochanter. Also, when the body position adjuster 10 is inserted into, for example, the lower body of the patient 300, it can support the patient 300 from the greater trochanter to the posterior surface of the lower leg (calf). The body position adjuster 10 has a shape and size corresponding to a plurality of patients 300.

[0021] The depth length L2 (front - rear direction length) of the body position adjuster 10 determines the insertion position of the body position adjuster 10. The depth length L2 of the body position adjuster 10 determines the height for lifting the scapula or thigh of the patient 300, and is a length considering the comfort and usability of the patient 300.

[0022] For example, when the patient 300 is lying in the center of the mattress 100, the insertion position is such that the rear surface portion 15 is aligned with the end of the bottom 210 of the bed 200. When the body position adjuster 10 is inserted to this position, the scapula and thigh of the patient 300 can be lifted (body position converted) by the necessary amount. The depth length L2 of the body position adjuster 10 is 270 mm or more and 460 mm or less (for example, 285 mm).

[0023] As a result, the body position adjuster 10 can suppress the occurrence of pressure sores in the patient 300 and suppress the patient 300 from assuming an uncomfortable body position. Also, since it is easy to know how far the body position adjuster 10 should be inserted, even a person not familiar with nursing care can perform the body position conversion of the patient 300.

[0024] The body position adjuster 10 has an upper surface portion 19 at the upper ends of the first to third inclined portions 16 to 18. The upper surface portion 19 is a flat surface in a rectangular shape with a depth length L3 and a width length L4. The depth length L3 is 55 mm or more and 150 mm or less (for example, 70 mm). The width length L4 is 200 mm or more and 500 mm or less (for example, 300 mm).

[0025] Since the bottom surface portion 11 and the upper surface portion 19 are flat surfaces and the height H2 is about 40 mm, the caregiver can easily insert and remove the body position adjuster 10 under the mattress 100 by gripping the bottom surface portion 11 and the upper surface portion 19. Further, in the body position adjuster 10, the upper surface portion 19 is a flat surface.

[0026] The required depth dimension of the body position adjuster is determined from the insertion amount. On the other hand, if the body position adjuster 10 is tilted as a whole without the flat upper surface portion 19, the posture of the patient 300 may become unstable. Since the upper surface portion 19 of the body position adjuster 10 is flat, the depth length L can be determined by adjusting the length of the upper surface portion 19. Further, the body position adjuster 10 can support the body at the first inclined portion 16 in front of the upper surface portion 19 so that the body does not get on the upper surface portion 19, thereby stabilizing the posture of the patient 300. Note that a handle (not shown) may be attached to the body position adjuster 10. The caregiver can take out the body position adjuster 10 from under the mattress 100 by pulling the handle, for example.

[0027] The first inclined portion 16 extends obliquely downward from the front end of the upper surface portion 19. The first inclined portion 16 connects between the front surface portion 12 and the upper surface portion 19. Since the body position adjuster 10 has a wedge shape in the front-rear direction due to the first inclined portion 16, it is easy to insert under the mattress 100.

[0028] The inclination angle α of the first inclined portion 16 determines the body posture of the patient 300. The inclination angle α of the first inclined portion 16 is a value that allows the patient 300 to perform a position change without forcing an unreasonable body posture.

[0029] If the inclination angle α of the first inclined portion 16 is large, the lifting of the scapula and thigh of the patient 300 becomes large, so there is a risk that the patient 300 will be compressed. Also, when the patient 300 is sleeping, there is a risk that the patient 300 will wake up. On the other hand, if the inclination angle α of the first inclined portion 16 is small, the lifting of the scapula and thigh of the patient 300 becomes small, so the body pressure distribution of the patient 300 becomes insufficient, and there is a risk that the prevention of bedsores will not be effectively achieved.

[0030] Therefore, the inclination angle α (the angle formed by the first inclined portion 16 and the horizontal) of the first inclined portion 16 is 6 degrees or more and 9 degrees or less (for example, 7 degrees). By setting the inclination angle α of the first inclined portion 16 in this way, the body position adjuster 10 can suppress the occurrence of bedsores without forcing the patient 300 into an unnatural body posture.

[0031]

[0030] The second inclined portion 17 extends obliquely downward from the left end of the upper surface portion 19. The second inclined portion 17 connects between the left side surface portion 13 and the upper surface portion 19. On the other hand, the third inclined portion 18 extends obliquely downward from the right end of the upper surface portion 19. The third inclined portion 18 connects between the right side surface portion 14 and the upper surface portion 19. The first inclined portion 16 is located between the second inclined portion 17 and the third inclined portion 18. The second inclined portion 17 and the third inclined portion 18 are formed symmetrically in the left - right direction.

[0032] The second inclined portion 17 and the third inclined portion 18 can give a natural inclination to the mattress 100 when the body position adjuster 10 is inserted under the mattress 100. The inclination angle β of the second inclined portion 17 and the third inclined portion 18 is 9 degrees or more and 24 degrees or less (for example, 15.5 degrees). In this case, the inclination angle α of the first inclined portion 16 is smaller than the inclination angle β of the second inclined portion 17 and the inclination angle β of the third inclined portion 18.

[0033] Thereby, the second inclined portion 17 and the third inclined portion 18 can, for example, make the posture around the neck or ankle of the patient 300 comfortable. Therefore, the body position adjuster 10 can prevent the occurrence of bedsores in the patient 300 without giving the patient 300 a sense of discomfort.

[0034]

[0031] The body position adjuster 10 has a hardness suitable for dispersing the body pressure of the patient 300 and a hardness suitable for the comfort of the patient 300. For example, in terms of 40% compression hardness (JIS K6400 - 2:2012 6.1 Method A), when compressed in the direction perpendicular to the first inclined portion 16, the body position adjuster 10 has a hardness of 200 N or more and 700 N or less (for example, 300 N).

[0035] In this way, the body position adjuster 10 has a size and shape that can perform body position conversion without giving discomfort to the patient 300. Further, the body position adjuster 10 has a size and shape that are easy for caregivers to use.

[0036] Next, the sheet 50 for the body position adjuster will be described.

[0037] If the insertion position of the body position adjuster 10 is not appropriate, there is a risk that pressure sores cannot be effectively suppressed from occurring in the patient 300. Therefore, in the present embodiment, a sheet 50 for the body position adjuster that can recognize at which position the body position adjuster 10 should be inserted is provided.

[0038] As shown in FIG. 5, the sheet 50 for the body position adjuster is attached to the mattress 100. Note that the sheet 50 for the body position adjuster may be attached to the bed 200. The sheet 50 for the body position adjuster has an insertion portion 53 that indicates the insertion position of the body position adjuster 10.

[0039] The sheet 50 for the body position adjuster has a main body portion 51 and an insertion portion 53 attached to the main body portion 51. The insertion portion 53 is, for example, a bag portion and is formed to have a size into which the body position adjuster 10 can be inserted. As shown in FIGS. 5 and 6, the insertion portion 53 has an opening on the side of the bed 200 (mattress 100) in a state where the sheet 50 for the body position adjuster is attached to the mattress 100.

[0040] As shown in FIG. 7, for example, two insertion portions 53 are provided side by side from the head side to the foot side on the side of the mattress 100 in the sheet 50 for the body position adjuster. The length dimension of the insertion portion 53 is, for example, substantially the same as the width length L1 of the body position adjuster 10. The depth dimension of the insertion portion 53 is, for example, substantially the same as the depth length L2 of the body position adjuster 10.

[0041] For example, if the bed 200 is an electric bed, the back bottom 211 rises and falls relative to the lumbar bottom 213, so that the buttocks of the patient 300 are positioned on the lumbar bottom 213. The bed or mattress may also display the sleeping position. When the patient 300 lies in this position and the body position adjustment device 10 is inserted into the head-side insertion section 53 as shown in FIG. 6, the body position adjustment device 10 can lift the patient 300 from the shoulder blade to the greater trochanter. On the other hand, when the body position adjustment device 10 is inserted into the foot-side insertion section 53, the body position adjustment device 10 can lift the patient 300 from the greater trochanter to the posterior part of the lower leg (calf).

[0042] In this way, the sheet 50 for body position adjustment devices allows even an unskilled caregiver to insert the body position adjustment device 10 into an appropriate position. This prevents the patient 300 from feeling uncomfortable and prevents bedsores from occurring in the patient 300.

[0043] As shown in FIG. 7, the sheet 50 for positioning adjustment devices may have a tag 55 having an insertion order 55a of the positioning adjustment devices 10. The tag 55 is provided at a position corresponding to each insertion part 53. The caregiver can recognize the next place to insert the positioning adjustment device 10 by checking the insertion order of the tag 55. This allows the patient 300 to change position efficiently. Even if there is a change in the caregiver, such as a night shift, the caregiver can intuitively know the next place to insert when taking over, and the order of insertion can be prevented effectively to prevent bedsores.

[0044] Also, in this example, the case where the size of the insertion part 53 consisting of a bag part is approximately the same as that of the body position adjustment device 10 has been described as an example. However, as shown in FIG. 7, the size of the insertion part 53 may be formed to be larger than that of the body position adjustment device 10. In such a case, for example, the body position adjustment device 10 may have a first mark 20. Meanwhile, the tag 55 may have a second mark 55b at a position corresponding to the first mark 20. The body position adjustment device 10 is positioned by aligning the first mark 20 with the second mark 55b and inserting it into the insertion part 53.

[0045] FIG. 8 is a plan view showing the seat for the body position adjuster according to the first modification. In the above-described embodiment, the insertion portion 53 has been described by taking the case where it is formed of a bag portion as an example. However, as in the first modification shown in FIG. 8, the insertion portion 60 may be a core material attached to the main body portion 51. This core material is made of, for example, a bead edge, fabric, polypropylene belt, flat rubber, stitch, etc. attached to the side surface or the back surface of the main body portion 51, and may have a color different from that of the main body portion 51. By making the color of the insertion portion 60 different from that of the main body portion 51, the insertion position of the body position adjuster 10 can be easily recognized.

[0046] FIG. 9 is a plan view showing the seat for the body position adjuster according to the second modification. As in the second modification shown in FIG. 9, the insertion portion 61 may be a tag attached to the main body portion 51. This tag is attached to, for example, the side surface or the back surface of the main body portion 51. On this tag, an insertion order or a mark may be shown as in the tag 55 shown in FIG. 7. Further, the length dimension in the longitudinal direction (from the head to the foot) of the main body portion 51 in the insertion portion 61 (tag) may be the same as the width length L1 of the body position adjuster 10.

[0047] FIG. 10 is a plan view showing the seat for the body position adjuster according to the third modification. As in the third modification shown in FIG. 10, the insertion portion 62 may be a mark provided on the main body portion 51. This mark is, for example, a print or a stabbing provided on the side surface or the back surface of the main body portion 51. This print or stabbing may have an insertion order or the like.

[0048] In the above-described embodiment, the seat 50 for the body position adjuster has been described by taking the case where it is used for the body position adjuster 10 as an example. However, the seat 50 for the body position adjuster is not limited to the body position adjuster 10 and can be used for body position adjusters having other shapes and sizes.

[0049] In the above-described embodiment, the seat 50 for a body position adjuster having four insertion portions 53 has been described as an example. However, a seat for a body position adjuster having one insertion portion on one side in the left-right direction may also be used. The body position adjuster 10 has, for example, a size that can be used even at one location on one side in the left-right direction.

[0050] The embodiment may include the following configurations. (Configuration 1) A top surface portion, A first inclined portion extending obliquely downward from the front end of the top surface portion, A second inclined portion extending obliquely downward from the left end of the top surface portion, A third inclined portion extending obliquely downward from the right end of the top surface portion, A body position adjuster inserted under a mattress, characterized by comprising: (Configuration 2) A bottom surface portion, A front surface portion extending upward from the front end of the bottom surface portion, A left side surface portion and a right side surface portion extending upward from both the left and right ends of the bottom surface portion, A rear surface portion extending upward from the rear end of the bottom surface portion, The first inclined portion extending obliquely upward to the rear from the upper end of the front surface portion, The second inclined portion extending obliquely upward to the right from the upper end of the left side surface portion, The third inclined portion extending obliquely upward to the left from the upper end of the right side surface portion, A top surface portion connecting the upper ends of the rear surface portion, the upper end of the first inclined portion, the upper end of the second inclined portion, and the upper end of the third inclined portion, A body position adjuster inserted under a mattress according to Configuration 1, characterized by comprising: (Configuration 3) The inclination angle of the first inclined portion is smaller than the inclination angles of the second inclined portion and the third inclined portion.
