Description

This invention relates to a support device. In electroencephalography (EEG), electrodes are placed in contact with the head to perform electrical measurements. A helmet-type EEG device is sometimes used in EEG measurements. Although unrelated to electroencephalogram (EEG) measurement devices, Patent Document 1 describes a height adjustment device for bedding that has a hollow chamber and allows the height of the hollow chamber to be adjusted to a higher position. Japanese Patent Publication No. 2013-075075 This is a perspective view of the support according to this embodiment.This diagram shows the usage status of the support device.This is Figure 1, illustrating an example of the configuration of the support according to this embodiment.Figure 2 illustrates an example of the configuration of the support according to this embodiment.Figure 3 illustrates an example of the configuration of the support according to this embodiment.Figure 4 illustrates an example of the configuration of the support according to this embodiment.Figure 5 illustrates an example of the configuration of the support according to this embodiment.Figure 6 illustrates an example of the configuration of the support according to this embodiment.This figure shows a first modified example of the support according to this embodiment.This figure shows a second modified example of the support according to this embodiment. The embodiments of the present invention will be described below with reference to the drawings. In all drawings, similar components are denoted by the same reference numerals, and their descriptions are omitted where appropriate. Figure 1 is a perspective view showing an overview of the support device 10 according to this embodiment. The support device 10 supports the head and cervical spine of a person wearing a headset 20 in a sleeping position. Figure 2 shows the support device 10 when supporting a subject in a sleeping position. The headset 20 is used, for example, in an electroencephalogram (EEG) measurement device. First, as shown in Figures 1 and 2, the support member 10 has the first region 110, the second region 120, and the third region 130 arranged in that order. As shown in Figure 2, the first region 110 is a region for supporting at least a portion of the subject's cervical spine, the second region 120 is a region for supporting at least a portion of the occipital region of the headset 20 worn by the subject, and the third region 130 is a region for supporting at least a portion of the occipital region of the headset 20 worn by the subject. However, each of the above regions may also include regions that support parts other than those described above, and regions that do not support (do not touch) the subject or the headset 20. Furthermore, the occipital region of the headset 20 is, for example, the portion of the headset 20 that includes an external point located vertically from the point that contacts the subject's occipital protuberance toward the outside of the headset 20, on the inside of the headset 20. For example, it is the region within 50 mm from the above point. Furthermore, the occipital region of the headset 20 is, for example, the portion that includes the highest point when the headset 20 is placed horizontally with the side that contacts the subject facing downwards. For example, the occipital region of the headset 20 is the region within 20 mm from the above point. In a top view, the lateral width W1 of the support 10 is not particularly limited, but is, for example, 400 mm or more and 750 mm or less. The vertical width W2 of the support 10 is also not particularly limited, but is, for example, 200 mm or more and 450 mm or less. However, these widths are not limited to these values. Furthermore, the lateral width W3 of the first region 110, the second region 120, and the third region 130 is not particularly limited, but for example, it is between 100 mm and 300 mm. Also, the lateral width W4 of the fourth region, described later, is not particularly limited, but for example, each is between 100 mm and 300 mm. Furthermore, the vertical width W5 of the first region 110 and the third region 130 is not particularly limited, but for example, it is between 20 mm and 150 mm. Also, the vertical width W6 of the second region 120 is not particularly limited, but for example, it is between 20 mm and 200 mm. Furthermore, the vertical width of the fourth region 140 is not particularly limited, but for example, it is approximately equal to the width W2. Furthermore, the thicknesses of the first region 110, the second region 120, and the third region 130 are, for example, between 10 mm and 200 mm. However, the thicknesses of the first region 110, the second region 120, and the third region 130 may be different. In a state where the headset and the subject's cervical spine are not supported, the upper surfaces of the first region 110, the second region 120, and the third region 130—in other words, the surfaces
