Each piece of information stored by the server 150 may be stored not in the server 150 but in the storage unit 16 of the bed 10, for example.

[Flow of excretion by the care recipient P]
The flow of the excretion by the care receiver P using the transfer assistance system 1 which concerns on this embodiment is shown to the flowchart of FIGS. 15-18. In this series of flows, the transfer support system 1 transfers the cared person P who is in the supine posture on the bed 10 to the toilet 50, and the cared person P who has excreted from the toilet 50 to the bed 10 Support both transfer and take a supine posture again.

First, as shown in FIG. 15, a carer performs preparation (step S1). The caregiver moves the sliding board 81 to the first position. In place of the preparation, for example, the care receiver P sets the position of the sliding board 81 at the first position immediately before the transfer of the care receiver P from the bed 10 to the toilet 50 (step S4) described later. It may be moved or the like.
Next, the care receiver P on the bed 10 uses the input unit 15 to perform an operation to start transfer support (step S2). At this time, the control unit 14 of the bed 10 receives a signal for starting assistance from the input unit 15, and the first process (step S3) shown in FIG. 16 is started.

  In the first step, first, the control unit 14 of the bed 10 remotely operates the toilet 50 to make the toilet 50 approach the bed 10 (step S31). At this time, first, the control unit 14 sends the identification number of the bed 10 to the server 150 through the communication unit 17 (step S311). The server 150 reads out the identification number of the toilet 50 associated with the identification number of the bed 10 (step S312), sends the position information of the bed 10 as the movement target to the toilet 50 of the identification number (step S313), 50 are moved toward the bed 10 (step S314). Furthermore, the server 150 reads out the first height and the second height associated with the identification number of the toilet 50 and sends them to the bed 10 (step S315).

  In addition, the method in which the server 150 acquires the positional information on the bed 10 is not particularly limited. When the bed 10 is used with a fixed position for a certain period, positional information of the bed 10 may be stored in the server 150 in advance in association with the identification number of the bed 10. When the position of the bed 10 changes frequently, the server 150 may also acquire the position information of the bed 10 when acquiring the identification number of the bed 10.

Thereafter, the control unit 14 of the bed 10 determines whether the positional relationship between the bed 10 and the toilet 50 is appropriate (step S32).
At this time, the control unit 14 acquires the positional relationship between the bed 10 and the toilet 50 from the position detector 91 (step S321). The control unit 14 determines whether or not the positional relationship between the two is appropriate (step S322), and when it is determined appropriate, displays that the light emitter 111 is appropriate (step S323). If it is determined that the light source 111 is inappropriate, it is displayed that the light emitter 111 is inappropriate (step S324). If the positional relationship is determined to be inappropriate, the control unit 14 of the bed 10 drives the third drive unit 62 of the toilet 50 via the communication unit 17 to move the toilet 50 (step S325). Thereafter, the control unit 14 determines again whether the positional relationship is appropriate (step S322).

If the positional relationship between the bed 10 and the toilet 50 is not appropriate even if movement of the toilet 50 (step S325) is repeated a predetermined number of times, for example, the control unit 14 of the bed 10 controls the communication unit 17 or the server 150. An alarm may be notified to a portable terminal owned by a caregiver or the like via
Also, in the subsequent steps including these steps, the bed 10 and the toilet 50 may communicate via the server 150, and the bed 10 and the toilet 50 may be connected in a peer-to-peer manner.

  By the way, when it is determined that the positional relationship is inappropriate, and the toilet 50 is moved (step S 325), the movement direction or movement amount of the toilet 50 is changed based on the detection result of the position detector 91. You may

  That is, for example, as shown in FIG. 11, when only the second switch 93b is ON and the first switch 93a is OFF, the positional relationship between the bed 10 and the toilet 50 is achieved by moving the toilet 50 in the second direction Y. It is likely that you can do it properly. However, as shown in FIG. 13, depending on the orientation of the toilet 50 with respect to the bed 10, the positional relationship may not be appropriate by merely moving the toilet 50 in the second direction Y. Therefore, in the process of repeating movement of the toilet 50 (step S325) a plurality of times, for example, after changing the direction of the toilet 50, the toilet 50 may be moved in the second direction Y.

  For example, as shown in FIG. 12, when only the first switch 93a is ON and the second switch 93b is OFF, the positional relationship between the bed 10 and the toilet 50 is achieved by moving the toilet 50 in the first direction X. There is a good chance that you can do it properly. However, as shown in FIG. 14, depending on the orientation of the toilet 50 with respect to the bed 10, the positional relationship may not be appropriate by merely moving the toilet 50 in the first direction X. Therefore, the toilet 50 may be moved in the first direction X after the direction of the toilet 50 is changed in the process of repeating the movement of the toilet 50 (step S325) a plurality of times.

  If the positional relationship between the bed 10 and the toilet 50 is appropriate in order to indicate whether the luminous body 111 is appropriate for the positional relationship, the luminous body 111 continues to light and the positional relationship between the bed 10 and the toilet 50 is inappropriate. In this case, the light emitter 111 may blink (light on intermittently). Alternatively, the light emitters 111 may emit light in different colors depending on whether the positional relationship is appropriate or inappropriate.

After the positional relationship between the bed 10 and the toilet 50 is determined to be appropriate, the control unit 14 adjusts the height of the bed 10 as shown in FIG. 20 (step S33).
When transferring from the bed 10 to the toilet 50, first, the height of the bed 10 is stopped at a height position at which the care receiver P can easily transfer from the bed 10 to the toilet 50. Generally, as shown in FIG. 19, the height of the bed 10 when the care recipient P goes to bed is often the minimum floor height from the viewpoint of safety, but the height is low From the state, the cared person P is not only difficult to transfer to the toilet 50, but also difficult to stand up. Therefore, in this case, the bottom 11 is raised to the above-described first height to raise the waist position of the care receiver P. At this time, the height of the bed 10 is equal to the height of the toilet seat 52 of the toilet 50 or slightly higher than the height of the toilet seat 52 as shown in FIG.

  Specifically, first, the control unit 14 of the bed 10 obtains the height of the bed 10 based on the detection result of the potentiometer 36. Thereafter, the control unit 14 obtains a difference between the height of the bed 10 obtained from the potentiometer 36 and the first height obtained from the server 150, and controls the first drive unit 33a to correspond to the difference.

As shown in FIG. 21 and FIG. 22, the control unit 14 of the bed 10 controls the second drive unit 34 a to raise the back bottom 21 (step S 34), and places the care recipient P in a long sitting position. .
Returning to FIG. 16, the control unit 14 of the bed 10 transmits a signal to the toilet 50 through the communication unit 17 to control the toilet 50, opens the lid 53 of the toilet 50, and moves the handrail 54 to the second position. (Step S35). At this time, the control unit 14 of the bed 10 causes the control unit 58 of the toilet 50 to control the first drive unit 56 and the second drive unit 57 of the toilet 50.

Thus, the first step is completed.
The height adjustment of the bed 10 (step S33) and the raising of the back bottom 21 (step S34) and the movement of the lid or the like (step S35) may be performed in parallel. In this case, the height adjustment (step S33) or the back elevation (step S34) may be synchronized with the movement of the lid or the like (step S35). Furthermore, the height adjustment (step S33), the back elevation (step S34), and the movement of the lid or the like (step S35) may be performed independently without synchronization.
After the height adjustment (step S33) and the back elevation (step S34), the movement of the lid or the like (step S35) may be performed.

Returning to FIG. 15, the care receiver P transfers from the bed 10 to the toilet 50 (step S4). At this time, the care receiver P changes the posture from the long sitting position to the end sitting position, as shown in FIGS. Thereafter, as shown in FIG. 26 and FIG. 27, it is transferred to the toilet 50 and sits on the toilet seat 52. In this process, as shown in FIG. 28, the care receiver P can move along the surface of the board 83, and transfer becomes easy.
Referring back to FIG. 15, after the care receiver P excretes (step S5), the user operates the cleaning using the input unit 59 of the toilet 50 (step S6). At this time, the control unit 58 of the toilet 50 receives a cleaning signal from the input unit 59, and the second process (step S7) shown in FIG. 17 is started.

In the second step, the toilet 50 cleans the excrement (step S71).
Further, the control unit 14 of the toilet 50 sends the information on which the cleaning operation has been performed through the communication unit 17 to the control unit 14 of the bed 10. When the control unit 14 of the bed 10 receives this signal, the control unit 14 of the bed 10 obtains information on the height of the bed 10 from the potentiometer 36 (step S72), and compares the height with the second height obtained from the server 150 It is determined whether or not it is appropriate (step S73).

If it is determined that it is appropriate, the height of the bed 10 is maintained as it is, and if it is determined that it is inappropriate, the control unit 14 adjusts the height of the bed 10 (step S74). The specific flow of this height adjustment is the same as the height adjustment in the first step. At this time, the care receiver P moves from the toilet 50 to the bed 10. Therefore, the height of the bed 10 is equal to the height of the toilet seat 52 or slightly lower than the height of the toilet seat 52.
Thus, the second step is completed.

Returning to FIG. 15, the care receiver P transfers from the toilet 50 to the bed 10 (step S8).
Thereafter, the care receiver P on the bed 10 performs an operation of ending the support using the input unit 15 (step S9). At this time, the control unit 14 of the bed 10 receives a signal for ending support from the input unit 15, and the third process (step S10) shown in FIG. 18 is started.

In the third step, the control unit 14 of the bed 10 adjusts the height of the bed 10 (step S101), and makes the height of the bed 10 the minimum floor height, for example. The control unit 14 controls the second drive unit to lower the back bottom 21 (step S102), and places the care recipient P in a supine posture.
In addition, the control unit 14 of the bed 10 transmits a signal to the control unit 14 of the toilet 50 through the communication unit 17 to control the toilet 50, closes the lid 53 of the toilet 50, and returns the handrail 54 to the first position. (Step S103). At this time, the control unit 14 of the bed 10 causes the control unit 58 of the toilet 50 to control the first drive unit 56 and the second drive unit 57 of the toilet 50. Thereafter, the control unit 14 of the bed 10 controls the third drive unit 62 of the toilet 50 through the communication unit 17 to retract the toilet 50 from the bed 10 (step S104).

  Thus, the third step is completed. Thereby, the excretion accompanied by transfer of the care recipient P is completed. The height adjustment of the bed 10 (step S101), the back of the back bottom 21 (step S102), the movement of the lid or the like (step S103), and the retraction of the toilet 50 (step S104) may be synchronized. It is not necessary to synchronize, and furthermore, these orders may be reversed.

  In addition, about evacuation of the toilet 50, the control part 14 of the bed 10 can determine based on the detection result of the position detector 91, for example. That is, as shown in FIG. 9, when the toilet 50 is separated from both the first member 94a and the second member 94b, both the first switch 93a and the second switch 93b are turned off. For example, after the toilet 50 starts the retraction operation, the control unit 14 of the bed 10 continuously acquires the detection results of the first switch 93a and the second switch 93b, and the first switch 93a and the second switch 93b. It can be determined that the toilet 50 has retreated from the bed 10 when both of the switches are turned off. At this time, the bed 10 can communicate with the server 150, and for example, the bed 10 can notify the server 150 that the toilet 50 has been retracted from the bed 10. When the toilet 50 is retracted from the bed 10, the control unit 14 of the bed 10 may instruct the toilet 50 on the movement direction or movement amount of the toilet 50 based on the detection result of the position detector 91.

  As described above, according to the transfer assistance system 1 according to the present embodiment, the second device 90 (position detector 91) detects the positional relationship between the bed 10 and the toilet 50. Therefore, for example, based on the detection result, it can be determined whether the positional relationship between the bed 10 and the toilet 50 is a positional relationship suitable for the first device 80.

  The third device 110 (the light emitter 111) performs at least one of displaying, generating a sound, and generating a vibration according to the positional relationship between the bed 10 and the toilet 50. Therefore, the care receiver P can easily recognize from the third device 110 whether the positional relationship between the bed 10 and the toilet 50 is a positional relationship suitable for the first device 80.

  Depending on the positional relationship between the bed 10 and the toilet 50, the fourth device 120 (each control unit 14, 58, each drive unit 33a, 34a, 56, 57, 62) is at least of the bed 10 and the toilet 50. Activate one. Therefore, the positional relationship between the bed 10 and the toilet 50 can be made suitable for the first device 80.

"2nd Embodiment"
A transfer support system 2 according to a second embodiment of the present invention will be described with reference to the drawings.
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only different points will be described.

  As shown in FIGS. 29 to 31, the transfer support system 2 according to the present embodiment is provided with a motorized fence 85 instead of the sliding board 81 as the first device 80. The electric fence 85 is provided with a foot light 86.

(Electric fence 85)
As shown in FIG. 29 and FIG. 28, the motorized fence 85 is aligned with the bottom 11 in the second direction Y.
The motorized fence 85 includes a main body 87 fixed to the gantry 12, a fence 88 capable of moving up and down with respect to the main body 87, and a board 89 fixed on the fence 88. The board 89 is foldable. The board 89 includes a first member 89a fixed on the fence 88 and a second member 89b hinged to the first member 89a.

The second member 89 b is held in line with the first member 89 a in the second direction Y. When the second member 89b moves relative to the first member 89a starting from the hinge, the second member 89b is superimposed on the first member 89a, or the second member 89b corresponds to the first member 89a. Are deployed.
The light emitter 111 is provided on the first member 89a. As shown in FIG. 30, in a state where the second member 89b is superimposed on the first member 89a, the light emitter 111 is covered by the second member 89b.

(Foot light 86)
As shown in FIGS. 29 and 30, the underfoot light 86 is provided on the main body 87. A foot light 86 illuminates the floor. The foot light 86 may be provided on the gantry 12 instead of the motorized fence 85. Furthermore, the foot light 86 may not be necessary.
As shown in FIG. 31, the motorized fence 85 and the foot light 86 are connected to the control unit 14 of the bed 10 and controlled by the control unit 14.

[Flow of excretion by the care recipient P]
The flow of the excretion by the care receiver P using the transfer assistance system 2 which concerns on this embodiment is based on the flowchart shown in FIG. Among the flowchart shown in FIG. 15, the preparation (step S1), the first step (step S3, see FIG. 32) and the third step (step S10, see FIG. 33) are different from the first embodiment.

In preparation (step S1), for example, the caregiver operates the input unit 15 to raise the motorized fence 85 as shown in FIG. Thereby, the fall of the care receiver P from the bed 10 is suppressed. Also, at this time, the caregiver deploys the board 89 in the second direction Y.
Thereafter, as shown in FIG. 32, in the first step (step S3), the determination as to whether the positional relationship between the bed 10 and the toilet 50 is appropriate (step S32) is performed in the same manner as in the first embodiment. When the height adjustment of the bed 10 is performed (step S33) and the back bottom 21 is raised up (step S34), in the present embodiment, as shown in FIG. 35, the descent of the motorized fence 85 and the foot light 86 Lighting is also performed (step S36). This prevents the transference of the care receiver P from being inhibited by the presence of the motorized fence 85.

  The timing for lowering the motorized fence 85 and lighting the foot light 86 (step S36) is to adjust the height of the bed 10 (step S33), raise the back of the back bottom 21 (step S34), move the lid, etc. The timing may or may not be synchronized with the implementation of step S35), and may be synchronized with these.

Thereafter, returning to FIG. 15, the steps up to the third step (step S10) are performed in the same manner as the first embodiment. In the third step, as shown in FIG. 33, raising of the motorized fence 85 and extinguishing of the foot light 86 are also performed (step S105).
The timing for raising the motorized fence 85 and turning off the foot light 86 (step S105) is the height adjustment of the bed 10 (step S101), the back lowering of the back bottom 21 (step S102), and movement of the lid or the like (step S102). It may be synchronized with or not synchronized with the implementation of the step S103) and the evacuation of the toilet 50 (step S104), and furthermore, the timing may be synchronized with these.

"3rd Embodiment"
A transfer support system 3 according to a third embodiment of the present invention will be described with reference to the drawings.
In the third embodiment, the same parts as the constituent elements in the second embodiment are denoted by the same reference numerals, the description thereof is omitted, and only different points will be described.

  In the transfer support system 3 according to the present embodiment, the signal for starting transfer support or the signal for ending transfer support is not a signal from the input unit 15 of the bed 10 but a signal from a sensor. Thereby, a series of flows of the excretion by the care receiver P can be implemented automatically, without operation by the care receiver P.

  In the present embodiment, as shown in FIG. 36, the bed 10 is provided with a pressure sensor 19 (for example, Sleep SCAN (registered trademark) of Paramount Bed Co., Ltd.). The pressure sensor 19 detects a change in the load of the care receiver P on the bed 10. The pressure sensor 19 is disposed, for example, between the bottom 11 and the mattress 26. The detection result of the pressure sensor 19 is sent to the control unit 14 of the bed 10.

The control unit 14 processes the detection result from the pressure sensor 19. Thereby, the control unit 14 acquires (estimates) biological information (for example, a heart rate, a cardiac cycle, a respiration frequency, a breathing cycle, a body movement, etc.) of the cared person P, or the posture of the cared person P (for example, It detects whether it is in the long sitting position or the end sitting position, etc., or detects whether it is in bed or out of bed. The biological information can be acquired based on, for example, information of fluctuation (body movement) of the load acting on the pressure sensor 19 based on the respiration of the care receiver P. The control unit 14 can also detect whether the care recipient P is sleeping or awake based on the biological signal.
The living body information of the cared person P, the change in the posture of the cared person P, and the presence and absence of the cared person P may be detected by means different from the pressure sensor 19.

The transfer support system 3 further includes a fifth device 130.
The fifth device 130 operates at least one of the bed 10 and the toilet 50 according to the load acting on at least one of the bed 10 and the toilet 50. The fifth device 130 operates at least one of the bed 10 and the toilet 50 based on the detection result of the pressure sensor 19.

  In the present embodiment, the control unit 14 of the bed 10 and the control unit 58 of the toilet 50 function as part of the fifth device 130. Furthermore, the first drive unit 33a and the second drive unit 34a of the bed 10, and the first drive unit 56, the second drive unit 57 and the third drive unit 62 of the toilet 50 also function as part of the fifth device 130. Do.

  That is, the control unit 14 of the bed 10 and the control unit 58 of the toilet 50 obtain the detection result of the pressure sensor 19 and determine the load that the care receiver P applies to the bed 10. Further, the control unit 14 of the bed 10 and the control unit 58 of the toilet 50 communicate with each other to drive the respective drive units 33 a, 34 a, 56, 57, 62 to operate the bed 10 and the toilet 50. In other words, each control unit 14, 58 and each drive unit 33a, 34a, 56, 57, 62 drive the bed 10 or the toilet 50 according to the load that the care receiver P applies to the bed 10, and Support Caregiver P transfer. In addition, detailed explanation is carried out in explanation of the flow of the excretion by the care receiver P mentioned later.

[Flow of excretion by the care recipient P]
The flow of the excretion by the care receiver P using the transfer assistance system 3 which concerns on this embodiment is shown in the flowchart of FIG.
In the first embodiment and the second embodiment, as shown in FIG. 15, the trigger of the start of the process mainly consisting of the transfer support system 3 such as the first process, the second process, the third process, etc. The caregiver P was inputting through the input unit 15. On the other hand, in the present embodiment, as shown in FIG. 37, the pressure sensor 19 detects a change in the care recipient P, and automatically performs transfer support.

In the present embodiment, after the caregiver performs preparation (step S1), the pressure sensor 19 detects a change in the state of the care receiver P (start of transfer) (step S2A).
For example, when the tendency of a specific movement occurs (for example, the body is shaken at a specific cycle, etc.) before excretion of the care receiver P, that is, when the specific load change tendency occurs, the storage unit 16 The tendency may be stored, and the control unit 14 may detect that the care receiver P starts to excrete by comparing the stored contents with the detection result of the pressure sensor 19. Alternatively, when the cared person P has different tendencies of body movement during sleep and awakening, the storage unit 16 stores the respective tendencies, and the control unit 14 stores the contents of each memory and the pressure sensor 19. By comparing the detection result with the detection result, when the care recipient P is awake, the first step may be performed on the assumption that excretion starts.

After the end of the first step, the care receiver P transfers from the bed 10 to the toilet 50 (step S4), and excrets (step S5). In addition, after excretion, the care receiver P operates the input part 15 of the toilet 50 at a suitable timing, and the toilet 50 wash | cleans excrement.
On the other hand, transfer of the care receiver P from the bed 10 to the toilet 50 is detected by the control unit 14 of the bed 10 based on the detection result of the pressure sensor 19 (step S6A), and the second step (step S7). ). For example, when the load detected by the pressure sensor 19 decreases, the control unit 14 can estimate that the care receiver P leaves the bed 10 and transfers to the toilet 50.

  The control unit 14 of the bed 10 detects that the cared person P after the excretion has transferred from the toilet 50 to the bed 10 again (step S8) based on the detection result of the pressure sensor 19 (step S9A). For example, when the load detected by the pressure sensor 19 increases, the control unit 14 can be estimated to be transferred from the toilet 50 to the bed 10.

  As described above, according to the transfer assistance system 3 according to the present embodiment, the fifth device 130 (each control unit 14, 58, each drive unit 33a, 34a, 56, 57, 62) includes the bed 10 and the bed In response to the load acting on at least one of the toilets 50, at least one of the bed 10 and the toilets 50 is operated. Therefore, for example, at least one of the bed 10 and the toilet 50 can be operated with the caretaker P merely performing a change in posture or the like without special operation.

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

[Modification of moving method of toilet 50]
In the embodiment, the third drive unit 62 moves the wheel 55 to move the toilet 50, but the present invention is not limited thereto. For example, a caregiver may move the toilet 50 without the third driving unit 62. In this case, the caregiver moves the toilet 50 in preparation (step S1) in the flowchart shown in FIG. At this time, the caregiver abuts the toilet 50 (the toilet bowl 51) to the first portion 97 and the second portion 98. In this state, the positional relationship between the bed 10 and the toilet 50 may be fixed using, for example, a jig (not shown).
In this case, at the beginning of the first step, instead of remotely operating the toilet 50 to make the toilet 50 approach the bed 10, whether the toilet 50 being positioned is the toilet 50 corresponding to the bed 10, Bed 10 may check. In this case, the bed 10 may acquire the identification number of the toilet 50, and it may be determined whether or not the identification number matches, for example, an identification number stored in advance in the storage unit 16 of the bed 10. If the two do not match, the control unit 14 of the bed 10 may notify an alarm via the communication unit 17 to a portable terminal owned by a caregiver or the like.

[Modification of position detector 91]
The position detector 91 may be configured to include a button 102 in place of the above-described roller 99 as in a position detector 91A according to a modification shown in FIG. In the position detector 91A according to this modification, the first switch 93a is turned on when the first button 102a is pressed, and the second switch 93b is turned on when the second button 102b is pressed.
The position detectors 91 and 91A may be provided not on the bed 10 but on the toilet 50. Furthermore, the position detectors 91, 91A may be independent of the bed 10 and the toilet 50.
The position detectors 91 and 91A are not limited to the configuration provided with the switch 93 described above. The position detector 91 is, for example, a pressure sensor, a piezoelectric sensor, a temperature sensor, an imaging device, an infrared sensor, an optical sensor, a magnetic sensor, an ultrasonic sensor, a position sensor, an angle sensor, a force sensor, an angular velocity sensor, a distance sensor, an acceleration sensor It is possible to adopt a configuration appropriately selected from among a gyro sensor, a voice input sensor, and the like.
In other words, the position detector 91 may not be configured to detect that the positional relationship between the bed 10 and the toilet 50 becomes a predetermined positional relationship, on the condition that the two switches 93 are turned on. It may be another configuration that can detect the position of the toilet 50 relative to the bed 10.
For example, even if a plurality of infrared sensors attached to the bed 10 are employed as the position detector 91 and the distance between each infrared sensor and the toilet 50 is measured, the positional relationship between the bed 10 and the toilet 50 is detected. Good. Further, for example, as the position detector 91, an imaging device for imaging the whole including the bed 10 and the toilet 50 from above is adopted, and for example, the positional relationship between the bed 10 and the toilet 50 by analyzing the imaging result. May be detected. When these infrared sensors or imaging devices are adopted as the position detector 91, the movement of the toilet 50 is controlled based on the detection result of the position detector 91 when the toilet 50 moves toward the bed 10. It is also good.
In addition, it is preferable that the installation position of the position detector 91 is a position which does not interfere with the action of the care receiver P in the daytime.

[Identifier of Caregiver P]
The control unit 14 of the bed 10 may acquire the identification number of the care receiver P. In this case, the storage unit 16 stores a database in which the identification number is associated with physical information (for example, height and weight) and medical condition of the care recipient P. The control unit 14 may acquire the physical information and the like of the cared person P from the acquired identification number of the cared person P, and may change the positional relationship between the bed 10 and the toilet 50 accordingly.
Further, the identification number of the toilet 50 may be associated with the identification number of the care receiver P, and it may be determined whether the toilet 50 is that of the care receiver P. In this case, the care receiver P can be prevented from using the toilet 50 of another person by mistake.
The information using the identification number of the care recipient P as a key may be stored, for example, in the server 150, or may be stored in the storage unit 16 of the bed 10. The identification information of the care receiver P may be acquired from, for example, an ID card or the like possessed by the care receiver P.

[Other modifications]
Although the control unit 14 of the bed 10 mainly controls the entire transfer support systems 1, 2 and 3, the present invention is not limited thereto. For example, a controller independent of the bed 10 and the toilet 50 may be provided, and the controller may control the entire transfer support system 1, 2, 3.

The swing arm 42 of the assistance bar 13 may be opened and closed by a drive unit (not shown).
The lid 53 and the handrail 54 of the toilet 50 may be moved manually, for example, without using the first drive unit 56 and the second drive unit 57. The lid 53 of the toilet 50 and the handrail 54 may not be necessary.
The bed 10 may not have a back-raising function or a knee-raising function. The height adjustment of the bed 10 may not be possible.

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