JP 2011-15971 A

However, in the conventional bed device, the user on the bed may feel a sense of obstruction due to the wall-like members, and the wall-like members may hinder caregivers or medical staff outside the bed device from checking the user's condition, so there is room for improvement in terms of convenience.

The present invention was made in consideration of the above-mentioned circumstances, and aims to improve convenience.

In order to solve the above problems, the present invention proposes the following means.
(1) The bed device of the present invention is characterized in comprising a bed, a wall-like member arranged on the periphery of the bed and positioned above the bed, and a transmissive information display unit provided on the wall-like member.

A transparent information display section is provided on the wall-shaped member. Therefore, when the information display section is transparent from the inside to the outside of the bed device, it is possible to suppress a sense of claustrophobia or anxiety felt by a user on the bed. Furthermore, when the information display section is transparent from the outside to the inside of the bed device, it is possible to facilitate a caregiver or medical professional outside the bed device to check the condition of the user, making it easier to check the condition even from a distance, for example. As a result, it is possible to improve convenience.

(2) In the bed device according to (1) above, the wall member may include side wall members arranged at the left and right ends of the bed, and the information display unit may be provided on the side wall members.

The information display unit is provided on the side wall member. Therefore, for example, when the user is in a lateral position on the bed, the user's face and the information display unit can easily face each other. This makes it easier to enhance the effect of suppressing the user's sense of claustrophobia and anxiety, which is achieved by making the information display unit transparent. It also makes it easier for caregivers and medical staff to view the user's face from the outside, making it easier to check the user's condition.

(3) The bed device according to (1) or (2) above may be configured to further include a detection unit that detects the state of a user on the bed, and a control unit that controls the information display unit based on the detection result of the detection unit.

The control unit is equipped with a control unit that controls the information display unit based on the detection results of the detection unit. Therefore, it is possible to automatically adjust the display of the information display unit according to the user's condition, further improving user convenience.

(4) In the bed device according to (3) above, the detection unit may be configured to include a first detection unit that detects whether the user is asleep.

The control unit controls the information display unit based on the detection result of the first detection unit. Therefore, for example, it is possible to automatically hide the information display unit when the user is awake, thereby further improving convenience for the user.

The present invention can improve convenience.

The board inlet hole 20 is formed on the upper surface of the board storage section 16. The board inlet hole 20 opens the inside of the board storage section 16 upward (to the outside).

The fence housing 17 is provided independently of the bed 14. The fence housing 17 is formed in a box shape having a fence intrusion hole 21 through which the fence body 13 emerges. The fence housing 17 is arranged at the left and right ends of the support frame 15. A pair of the fence housing 17 is provided on either side of the support frame 15 in the left and right direction. Furthermore, a pair of the left and right fence housing 17 is provided with a gap in the front-rear direction. A total of four fence housing 17 are provided. Each fence housing 17 is adjacent to the support frame 15 from the outside along the left-right direction. Each fence housing 17 is formed to have the same shape and size. Each fence housing 17 is formed to be a hollow rectangular parallelepiped that is long in the front-rear direction. The fence intrusion hole 21 is formed on the upper surface of the fence housing 17. The fence intrusion hole 21 opens the fence housing 17 upward (to the outside).

The board 12 includes a headboard 22 located on the head side H along the front-rear direction, and a footboard 23 located on the foot side F along the front-rear direction. The headboard 22 is a fixed board that is fixed substantially immovably to the bed device main body 11. The footboard 23 is a movable board that is movably connected to the bed device main body 11. The footboard 23 is connected to the bed device main body 11 so that it can be raised and lowered freely.

The footboard 23 can be freely accommodated in the board storage section 16. The footboard 23 is connected to the board storage section 16 via a board movement mechanism (not shown). The board movement mechanism moves the footboard 23 through the board ingress/egress hole 20 into and out of the board storage section 16. A board top plate 24 is provided on the upper surface of the footboard 23. The board top plate 24 is formed in a rectangular shape that is long in the left-right direction in a plan view, and covers the footboard 23 from above. The board top plate 24 abuts against the upper surface of the board storage section 16 when the footboard 23 is accommodated in the board storage section 16.

The fence bodies 13 are disposed at the left and right ends of the support cradle 15. A pair of fence bodies 13 are provided, sandwiching the support cradle 15 in the left and right direction. Furthermore, the pair of left and right fence bodies 13 are provided as a pair with a gap in the front-to-rear direction. A total of four fence bodies 13 are provided. Each fence body 13 is a movable fence that is movably connected to the bed device main body 11. Each fence body 13 is connected to the bed device main body 11 so that it can be raised and lowered freely.

Each fence body 13 can be freely accommodated in the fence housing section 17. Each fence body 13 is connected to the fence housing section 17 via a fence movement mechanism (not shown). The fence movement mechanism causes each fence body 13 to appear and disappear through the fence appearance hole 21 into the interior of the fence housing section 17. A fence top plate 25 is provided on the upper surface of each fence body 13. The fence top plate 25 is formed in a rectangular shape that is long in the left-right direction in a plan view, and covers each fence body 13 from above. The fence top plate 25 abuts against the upper surface of the fence housing section 17 when the fence body 13 is accommodated in the fence housing section 17.

When the user is sleeping on the bed device 10, as shown in FIG. 1, the footboard 23 and all of the fences 13 are moved to a raised position protruding upward from the bed device main body 11. This makes it possible to prevent the user from falling unintentionally. In the raised position, the footboard 23 (board 12) faces the bed device main body 11 in the front-to-rear direction, and the fences 13 face the bed device main body 11 in the left-to-right direction.

When the user leaves the bed from the head side H, or when the operator of the bed device 10 (e.g., a nurse or caregiver) performs treatment on the upper body of the user, a pair of left and right fence bodies 13 located on the head side H out of the multiple fence bodies 13 are lowered from the raised position and stored in the fence storage section 17. At this time, the fence bodies 13 move to a lowered position (storage position) lower than the raised position, and the fence top plate 25 abuts against the upper surface of the fence storage section 17. In the lowered position, the fence bodies 13 are located lower than the mattress 19.

When the user gets out of bed on the foot side F or when the operator performs treatment on the upper body of the user, the pair of left and right fence bodies 13 located on the foot side F among the multiple fence bodies 13 are lowered from the raised position of the fence bodies 13 and stored in the fence storage section 17. At this time, the fence bodies 13 move from the raised position to the lowered position, and the fence top plate 25 abuts against the upper surface of the fence storage section 17.
When a user transfers between the bed device main body 11 and another device, all of the fence bodies 13 are lowered from the raised position to the lowered position and stored in the fence storage section 17.

When setting up a line (e.g., a tube) to intubate the lower half of the user's body, the footboard 23 is lowered from the raised position of the board 12 and stored in the board storage section 16. At this time, the footboard 23 moves to a lowered position (storage position) lower than the raised position, and the board top plate 24 abuts against the upper surface of the board storage section 16. In the lowered position, the footboard 23 is located lower than the mattress 19.

In the case of an emergency or when making the bed, all of the fence bodies 13 and the footboard 23 are lowered from the raised position to the lowered position and stored within the fence storage section 17 or the board storage section 16.
The movement of the fence body 13 and the footboard 23 (board 12) may be electric or manual. In the case of electric movement, a switch for movement may be provided, for example, in the fence housing section 17 or the board housing section 16. The switch may also be provided in another operating device, for example, a controller that can be operated by the user.

In the bed device 10, the board 12 and the fence body 13 are wall-like members 26 arranged on the periphery of the bed 14. The fence body 13 of the wall-like members 26 is a side wall-like member arranged on the left and right ends of the bed 14. The wall-like member 26 is located above the bed 14. The wall-like member 26 prevents, for example, a user on the bed 14 from unintentionally falling off.

The wall-like members 26 divide the space above the bed 14 into an intra-bed space Si and an extra-bed space So. The intra-bed space Si is formed by the inner surface 26a of each wall-like member 26 that faces the bed 14. The intra-bed space Si has the bed 14 (mattress 19) as its bottom surface. The extra-bed space So is formed by the outer surface 26b of each wall-like member 26 that faces outside the bed device 10. The extra-bed space So is the external space of the bed device 10.

The wall member 26 is provided with an information display section 27. The information display section 27 can be switched between displaying and not displaying information. The information display section 27 is transparent. In this embodiment, the information display section 27 is transparent from the inside to the outside of the bed device 10. Furthermore, the information display section 27 is also transparent from the outside to the inside of the bed device 10.

The information display section 27 is transparent at least when no information is displayed. As shown in FIG. 1, the information display section 27 is fully transparent when no information is displayed. As shown in FIG. 3, the information display section 27 can be semi-transparent when information is displayed. In a semi-transparent information display section 27, not only is the displayed information visible, but people or objects on the opposite side of the information display section 27 can also be seen through the information.

The information display unit 27 is powered by electricity, and the information displayed can be switched. In the illustrated example, the information display unit 27 is formed by a display (e.g., an organic EL display). It is also possible to apply a head-up display to the information display unit 27.

The information display unit 27 is provided on each of the footboard 23 and all of the fence bodies 13. The information display unit 27 is disposed in the center of the wall member 26 when viewed from the front. The information display unit 27 is exposed on both the inner surface 26a and the outer surface 26b of each wall member 26, and faces both the space inside the bed Si and the space outside the bed So. The space inside the bed Si is visible from the space outside the bed So through the information display unit 27, and the space outside the bed So is visible from the space inside the bed Si through the information display unit 27. The information display unit 27 is visible from a user lying on the bed 14. At least a portion of the information display unit 27 is disposed at a position equivalent in the front-to-back direction to the face of a user lying on the bed 14, and faces the face in the left-to-right direction.

As shown in Figures 3 and 4, the information display unit 27 can display information (hereinafter referred to as "outward information") directed toward the outside of the bed device 10 (external bed space So). The outward information is displayed on the outer display surface 27b of the information display unit 27. The outer display surface 27b is exposed to the outer surface 26b. The information display unit 27 can display, as outward information, for example, biological information as described below.

As shown in FIG. 5, the information display unit 27 can also display information (hereinafter referred to as "inward information") directed toward the inside of the bed device 10 (the space inside the bed Si). The inward information is displayed on the inner display surface 27a of the information display unit 27. The inner display surface 27a is exposed to the inner surface 26a.

The information display unit 27 can display still images such as photographs and videos such as television broadcasts as the inward information. The information display unit 27 can also display images of a location desired by the user on the bed 14, such as a remote location or a resort, as still images (including a slideshow of still images) or videos. The information display unit 27 can also display emails addressed to the user, news that matches the user's preferences, and the like.

The information display unit 27 is capable of switching between transmission and non-transmission while displaying at least one of the outward information and the inward information. The information display unit 27 is equipped with a light-blocking mechanism (not shown). The light-blocking mechanism is disposed between the outer display surface 27b and the inner display surface 27a in the information display unit 27. The light-blocking mechanism switches between allowing and restricting light transmission between the outer display surface 27b and the inner display surface 27a.

As shown in FIG. 3, when the information display unit 27 displays information and the light blocking mechanism is not activated and the information display unit 27 is transparent, the information display unit 27 becomes semi-transparent as described above. For example, when the information display unit 27 is in a semi-transparent state and the outward information of the information display unit 27 is viewed from the space Si inside the bed, the outward information appears in an inverted state.

As shown in Figures 4 and 5, when the information display unit 27 is displaying information and the light blocking mechanism is activated to make the information display unit 27 opaque, the background of the information displayed by the information display unit 27 becomes opaque, making it easier to see the information.

As shown in Figures 3 to 5, the information display unit 27 can display only one of the outward information and the inward information. As shown in Figure 6, the information display unit 27 can also display both the outward information and the inward information simultaneously. In this case, it is preferable that the information display unit 27 is non-transparent to ensure the visibility of the information. The outward information and the inward information may be different information from each other, or may be the same information.

If it is desired to provide sound in conjunction with the display of information on the information display unit 27, for example, it is possible to provide audio equipment such as earphones (earphone jack) and speakers in the bed device 10. In this case, the audio equipment may be provided in the bed device main body 11 (support stand 15), the board 12, or the fence body 13. Furthermore, the audio equipment may be provided on the walls or ceiling of a room. If speakers are used as the audio equipment, by using speakers with directionality, it is possible to make it easier to limit the sound from the speakers to the user, even if the speakers are placed on the ceiling, for example.

As shown in FIG. 2, the bed device 10 further includes a measurement unit 29 , an operation unit 30 , a detection unit 31 , and a control unit 33 .
The measurement unit 29 measures biological information of the user on the bed 14. The measurement unit 29 measures, for example, the heart rate, blood pressure, etc. of the user. As the measurement unit 29, a known medical device can be appropriately adopted.

The operation unit 30 accepts input of operation information from the outside. The operation unit 30 is operated, for example, by a user on the bed 14 or by a caregiver outside the bed device 10. For example, a so-called environmental control device can be used as the operation unit 30. For example, a touch panel provided integrally with the information display unit 27 can also be used as the operation unit 30. For example, a configuration that accepts input of operation information based on voice or human movement (gestures) can also be used as the operation unit 30. For example, a switch that switches the display ON/OFF can be provided on each wall-like member 26 as the operation unit 30.

The detection unit 31 detects the state of a user on the bed 14. The detection unit 31 includes a first detection unit 34 and a second detection unit 35.
The first detector 34 detects whether or not the user on the bed 14 is asleep. As the first detector 34, a known sleep state determination device can be appropriately adopted.

The second detection unit 35 detects the sleeping position and orientation of the user on the bed 14. The second detection unit 35 can appropriately adopt a known configuration for detecting the sleeping position and orientation of the user on the bed 14.
The second detection unit 35 may be configured to include, for example, a load sensor that crosses the bed 14 in the left-right direction. In this case, the second detection unit 35 can detect the left-right position of the user on the bed 14 based on the distribution of the magnitude of the load detected by the load sensor.

The second detection unit 35 can estimate the sleeping position of the user according to the user's position in the left-right direction. That is, for example, when the user is located in the center in the left-right direction, the second detection unit 35 can estimate the sleeping position of the user as supine, and when the user is located at the end in the left-right direction, the second detection unit 35 can estimate the sleeping position of the user as lateral.
The second detection unit 35 can also estimate the orientation of the user depending on the user's position in the left-right direction. That is, for example, when the user is located at the left end in the left-right direction, it can be estimated that the user is in a lateral position and facing the left side, and when the user is located at the right end in the left-right direction, it can be estimated that the user is in a lateral position and facing the right side.

The control unit 33 acquires the measurement results of the measurement unit 29, the input information to the operation unit 30, and the detection results of the detection unit 31. The control unit 33 controls the display of information on the information display unit 27. As shown in FIG. 3, the control unit 33 can cause the information display unit 27 to display the user's bioinformation based on the measurement results of the measurement unit 29. The information display unit 27 displays the bioinformation, for example, toward the space outside the bed So (as the outward information).

The control unit 33 controls the information display unit 27 based on the detection results of the detection unit 31. This makes it difficult for a user on the bed 14 to unintentionally view his or her own biometric information displayed on the information display unit 27.

For example, the control unit 33 may switch between displaying and stopping the information display unit 27 based on the detection result of the first detection unit 34. That is, when the first detection unit 34 detects that the user is asleep, the control unit 33 may display the information display unit 27. When the first detection unit 34 detects that the user is not asleep (the user is awake), the control unit 33 may stop the display of the information display unit 27. Also, as shown in FIG. 4, when the first detection unit 34 detects that the user is not asleep, the control unit 33 may make the information display unit 27 non-transparent. That is, the control unit 33 may switch between transparent and non-transparent states of the information display unit 27 based on the detection result of the first detection unit 34.

Furthermore, for example, the control unit 33 may switch between the information display units 27 that perform display and the information display units 27 that stop displaying, among the multiple information display units 27, based on the detection result of the second detection unit 35. That is, when the second detection unit 35 detects that the user is facing left on the bed 14, the control unit 33 can stop displaying the information display unit 27 located to the left of the user, while displaying the information display unit 27 located to the right of the user. In this case, it is possible to prevent the user's biometric information from being displayed on the wall-like member 26 (fence body 13) facing the user.

As described above, according to the bed device 10 of this embodiment, the wall member 26 is provided with a transparent information display section 27. This can reduce the sense of claustrophobia or anxiety felt by the user on the bed 14. This also makes it easier for caregivers or medical staff outside the bed device 10 to check the condition of the user, making it easier to check the condition even from a distance, for example. As a result, convenience can be improved.

The information display unit 27 is provided on the fence body 13. Therefore, for example, when the user is in a lateral position on the bed 14, the user's face and the information display unit 27 can be easily faced directly. This makes it easier to enhance the effect of suppressing the user's sense of claustrophobia and anxiety, which is achieved by the information display unit 27 being transparent. Additionally, it also makes it easier for caregivers and medical staff to view the user's face from the outside, making it easier to check the user's condition.

The control unit 33 controls the information display unit 27 based on the detection result of the detection unit 31. Therefore, it becomes possible to automatically adjust the display of the information display unit 27 according to the state of the user, and it is possible to further improve the convenience for the user.
The control unit 33 controls the information display unit 27 based on the detection result of the first detection unit 34. Therefore, for example, it becomes possible to automatically put the information display unit 27 into a non-display state when the user is in an awake state, thereby further improving convenience for the user.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

In the above embodiment, the information display unit 27 is transparent from the inside to the outside of the bed apparatus 10, and also transparent from the outside to the inside of the bed apparatus 10. However, the present invention is not limited to this. For example, the information display unit 27 may be transparent only from the inside to the outside of the bed apparatus 10, and non-transparent from the outside to the inside of the bed apparatus 10. Conversely, the information display unit 27 may be non-transparent from the inside to the outside of the bed apparatus 10, and transparent only from the outside to the inside of the bed apparatus 10.

The board 12 and the fence 13 do not have to be movably connected to the bed device main body 11. The board 12 and the fence 13 may be fixed substantially immovably in a state where they are positioned above the bed 14. The board 12 and the fence 13 may be detachably connected to the bed device main body 11.
The wall-like members 26 such as the board 12 and the fence 13 may be formed, for example, from a lattice made by combining pipe members. In this case, the information display unit 27 may be fitted into the hole.

The measurement unit 29, operation unit 30, and detection unit 31 may not be provided. For example, the control unit 33 may change the display content of the information display unit 27 or switch between display and non-display depending on the current time, display time, etc.

In addition, the components in the above embodiment may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-mentioned modifications may be combined as appropriate.
