Next, the details of the method of creating the height scale 2 of the bed alignment scale 1 shown in FIG. 2 will be described.
<Experiment to determine the position of the bed that suits the operation using the angle adjustment function>
(experimental method)
(1) The position of the subject who sleeps on the electric bed 3 (distance between the parietal and upper anterior iliac spines: 838 mm) is within the range where the horizontal distance between the inner surface 4A of the headboard 4 and the upper anterior iliac spine of the subject is 850 mm to 950 mm. Is changed in the longitudinal direction of the electric bed 3 by 10 mm.
(2) At each position of the subject, the back bottom 6 of the electric bed 3 is raised from the horizontal posture to the maximum angle (70 degrees) and then returned to the original horizontal posture, and the inner surface 4A of the headboard 4 and the top of the subject's head Measure the distance change (deviation amount).
(Experimental result)
When the horizontal distance between the inner surface 4A of the headboard 4 and the upper anterior iliac spine of the subject was 900 mm, the shift amount was minimal.
Therefore, as the bed position suitable for the operation by the back raising angle adjustment function, the position of the horizontal distance L = 900 mm away from the inner surface 4A of the head board 4 to the foot board 5 shown in FIG. And

<Relationship between human height and sacrum>
Data on Japanese human body dimensions (Makiko Kawauchi, Masaaki Mochimaru, Hiroshi Iwasawa, Seiji Mitani (2000): Japanese Human Body Size Database 1997-98, Living and JIS Center, Industrial Technology Institute, Ministry of International Trade and Industry) As shown in FIG. 5, the horizontal axis (X) is plotted as “height (mm)” and the vertical axis (Y) is plotted as “length from the top of the head to the superior anterior iliac spine (mm)”. When approximated as a quadratic function and a coefficient was obtained by the method of least squares, the following equation (1) was obtained.

                      Y = 0.4284X + 57.551 (1)

<Creation of height scale 2 of bed positioning scale 1>
The length (mm) from the top of the head to the upper anterior iliac spine (sacrum) in the height of the user A of the electric bed 3 is obtained from the formula (1) as “the length between the top and the sacrum” in FIG. It is done.
Therefore, the reference bending position P of the electric bed 3 is a position of a horizontal distance L = 900 mm away from the inner surface 4A of the head board 4 toward the foot board 5 as described above, so that the user is directly above the reference bending position P. The height scale 2 of the bed alignment scale 1 for positioning the upper anterior iliac spine (sacrum) of A is obtained by subtracting “the length between the parietal and sacrum” (mm) of FIG. 6 from 900 (mm). The required “height” corresponding to the “headboard-top length” (in FIG. 2, cm) may be written as the “headboard-top length” (mm) in FIG.

In the above description, the case where the heel bed alignment scale 1 has a scale of height determined based on the correlation between the height of the person and the sacrum (for example, the superior anterior iliac spine) has been shown. The alignment scale 1 may have a height scale determined based on a correlation between a person's height and a hip joint (for example, a trochanter point).
Moreover, in the above description, the reference position of the electric bed 3 is the inner surface 4A of the headboard 4, and the case where the user's A head B is aligned using the bed alignment scale 1 is shown. 3, the sole C of the user A (see FIG. 1) may be aligned with the inner surface 5 </ b> A of the footboard 5.

According to the bed positioning method of the user A for the electric bed 3 performed using the bed positioning scale 1 as described above, the reference position 1A of the bed positioning scale 1 is arranged in accordance with the reference position of the electric bed 3. In this state, the user A's head B or sole C is aligned so as to match the height corresponding to the height of the user A in the height scale 2 of the bed alignment scale 1, so that the user whose position is difficult to understand Since it is not necessary to search for the sacral portion of A (for example, the superior anterior iliac spine) and the hip joint (for example, the trochanter point), accurate bed positioning can be performed.
In addition, the saddle bed alignment scale 1 arranged in accordance with the reference position of the electric bed 3 is used without using the mark sticker attached to the side surface of the electric bed, which is often hidden by a mattress, a sheet or the like. The bed positioning operation of the user A becomes easy.

Further, the reference bending position P of the electric bed 3 is determined based on the experiment so that the amount of displacement of the person's body is minimized when the electric bed 3 is raised up. Since the height scale 2 of the bed positioning scale 1 is set so that the sacrum or hip joint of the user A is located immediately above the reference bending position P, the user A's It is possible to perform the bed positioning more accurately.
Furthermore, since the reference position of the electric bed 3 is the inner surface 4A of the headboard 4 of the electric bed 3 or the inner surface 5A of the footboard 5 of the electric bed 3, the electric bed 3 that matches the reference position 1A of the floor alignment scale 1 is used. Therefore, the user A's bed positioning operation using the bed positioning scale 1 is further facilitated.

Furthermore, since the bed alignment scale 1 is an elongated and thin sheet, it can be easily cut. Therefore, it cut | disconnects by the scale corresponding to the height of the user A in the height scale 2, and the cut part (tip of the sheet-like bed alignment scale 1) 1C can be aligned with the top B or the sole C of the user A. Therefore, the user A can easily perform the bed positioning operation.
In addition, since the base end portion 1B of the bed alignment scale 1 is attached to the inner surface 4A of the headboard 4 or the inner surface 5A of the foot board 5 and hangs down, the bed alignment scale 1 is placed horizontally when used. It can be used quickly and easily by extending, and after use, it hangs down along the inner surface 4A of the headboard 4 or the inner surface 5A of the footboard 5, so that it does not interfere with the user A or the caregiver.
Furthermore, since the floor alignment scale 1 hangs down from the inner surface 4A of the headboard 4 or the inner surface 5A of the footboard 5 when not in use, it is prevented from being lost or damaged.
