Description

The present invention relates to a setting state confirmation device for a seating detection type nurse call system, and in particular, is currently a seating detection type nurse call system that detects an action in which a patient is trying to leave the toilet seat and makes a call. It is related to a device for confirming the state of.

Generally, in hospitals and long-term care facilities, when a patient or care recipient (hereinafter simply referred to as "patient") who needs assistance wants to use the toilet, he / she operates the bedside call button to operate the nurse or long-term care. Call a teacher (hereinafter simply referred to as a "nurse"). In response, the nurse assists the patient in getting up from bed, moving to the toilet, and sitting on the toilet seat. If the patient takes a long time to finish the stool, the nurse goes out of the toilet. Then, the patient operates the call button in the toilet after the stool is finished to call the nurse again. The nurse who receives this call assists the patient in getting up from the toilet seat and moving to the bed.

By the way, some patients who need assistance are prohibited from standing up from the toilet seat by themselves when using the toilet because of a disability in the lower limbs. However, some of these patients stand up on their own without calling, which can exacerbate their disability. In order to prevent such a situation, a device is provided that detects that the patient is about to get up from the toilet seat and automatically calls.

However, in this type of device, since the call is automatically made when the patient tries to get up from the toilet seat, there is a problem that the call is made even when the patient who does not need assistance uses the toilet. Therefore, for the purpose of solving such a problem, the patient's departure from the toilet seat is automatically detected by a signal from a sensor that detects that the body assist device provided upside down in front of the toilet seat has stood up. A toilet device has been proposed in which the function for making a call is effective only when the administrator operates a switch lever type instruction means provided in the toilet (see, for example, Patent Document 1). ).

On the other hand, a sensor for detecting the position of the arm portion is provided for a body assisting tool having an arm portion that rotates vertically or horizontally with one end as a rotation fulcrum, and the user can use the sensor based on a signal from the sensor. There is known a toilet device that notifies that the person is about to leave the toilet seat (see, for example, Patent Document 2). In the toilet device described in Patent Document 1, the configuration described in Patent Document 2 can be adopted as a specific configuration for detecting the separation from the toilet seat.

When the calling function is configured to be switched on / off as in Patent Document 1, it is required to appropriately turn the calling function on / off. That is, if the nurse forgets to turn on or off the call function, there is a risk of false notification or omission of notification of the nurse call. Further, when the configuration described in Patent Document 1 or Patent Document 2 is used as the secession detection means, it is also possible to appropriately set the on / off of the calling function according to the state of use / non-use of the body assist device. Desired.

Therefore, an object of the present invention is to make it possible to easily confirm whether or not the on / off setting state of the calling function and the use / non-use state of the body assist device are appropriate.

In order to solve the above-mentioned problems, in the present invention, the on / off setting state of the calling function set according to the user operation on the operation unit and the physical aid used by the patient sitting on the toilet seat are detected. and to perform for the display corresponding to the pattern of the combination of the detection state of use / non-use in a display device.

According to the present invention configured as described above, the on / off setting state of the calling function and the use / non-use state of the body assist device can be confirmed by the display of the display device, respectively, so that the calling function can be confirmed. It is possible to easily confirm whether the on / off setting state and the use / non-use state of the body assist device are appropriate.

It is a figure which shows an example of the equipment installed in a toilet. It is a block diagram which shows the functional structure example of the sensor control unit by this embodiment. It is a figure which shows the modification of the body assisting tool.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a configuration example of a seating detection type nurse call system to which the setting state confirmation device of the present embodiment is applied. As shown in FIG. 1, the nurse call system of the present embodiment includes a nurse call master unit 1, a controller 2, a representative corridor light 3, a sensor control unit 4, a distance measuring sensor 5, and a call button 6. There is. Of these, the sensor control unit 4, the distance measuring sensor 5, and the call button 6 are embedded and installed in the wall surface of the toilet or the like.

The call button 6 is a button for a patient using the toilet to call a nurse. When the patient operates the call button 6, a call signal is transmitted to the nurse call master unit 1 via the representative corridor light 3 and the controller 2, and a predetermined call operation is executed. For example, if the nurse once sits out of the toilet after the patient is seated on the toilet seat, the patient can call the nurse by operating the call button 6 after the stool is finished.

The sensor control unit 4 and the distance measuring sensor 5 are for detecting an operation in which a patient requiring assistance in the toilet is trying to leave the toilet seat and automatically calling the patient. That is, when the movement of the patient trying to leave the toilet seat is detected by the sensor control unit 4 and the distance measuring sensor 5, a call signal is sent from the sensor control unit 4 via the representative corridor light 3 and the controller 2 to the nurse call parent. It is transmitted to the machine 1 and a predetermined calling operation is executed. Further, the sensor control unit 4 includes the setting state confirmation device of the present embodiment.

The nurse call master unit 1 executes a predetermined calling operation in response to the above-mentioned call, and is installed in, for example, a nurse center. The ringing operation is performed, for example, by outputting a ringing tone from the speaker, displaying a screen on a display for indicating the toilet in which the call is being made, or the like. The nurse call master unit 1 allows a nurse to respond to this call operation. For example, when the nurse off-hooks the handset and responds, the calling operation stops.

The controller 2 is arranged between the nurse call master unit 1 and the representative corridor light 3, and controls calls and data transmission / reception. The representative corridor light 3 is installed outside near the entrance of the toilet. The representative corridor light 3 is provided with a display device 31 such as a liquid crystal display or an organic EL display so that it can be displayed that a call has been made. When the call is not being made, the display device 31 displays the on / off setting state of the call function and the use / non-use state of the body assist device 200. In addition, the representative corridor light 3 is provided with a recovery button for the nurse to respond to the call. When the nurse operates the recovery button, the call operation stops.

FIG. 2 is a diagram showing an example of equipment installed in the toilet. As shown in FIG. 2, a toilet bowl 100 and a physical aid 200 provided above the front of the toilet bowl 100 are installed in the toilet. The body assisting tool 200 has a support portion 201 and an arm portion 202 extending in one direction from the support portion 201. The support portion 201 is provided on the wall surface of the toilet. One end of the arm portion 202 is supported by the support portion 201, and the arm portion 202 is configured to be rotatable in the vertical direction (arrow A direction) with the support portion 201 as a rotation fulcrum.

When the nurse seats the patient in need of assistance on the toilet seat 101 of the toilet bowl 100, the arm portion 202 is rotated downward so that the arm portion 202 crosses the front upper part of the toilet bowl 100. (Usage state of body aid 200). As a result, the arm portion 202 prevents the patient seated on the toilet seat 101 from falling forward. The patient can also grip the arm portion 202 or place the arm on the arm portion 202.

After that, when the nurse assists the patient to leave the toilet seat 101, the arm portion 202 is rotated upward to stand up so that the arm portion 202 does not cross the front upper part of the toilet bowl 100. (A state in which the body assist device 200 is not used). This allows the patient to stand up (leave) from the toilet seat 101. At this time, the nurse assists the patient in getting up from the toilet seat 101.

Here, the patient seated on the toilet seat 101 cannot stand up unless the arm portion 202 is rotationally moved upward. Therefore, if the position of the arm portion 202 is detected, it is possible to detect that the patient is about to leave the toilet seat 101. In order to detect this, in the present embodiment, the distance measuring sensor 5 is provided on the wall surface in the vicinity of the support portion 201. In the example of FIG. 2, the distance measuring sensor 5 is arranged on the left side at substantially the same height as the support portion 201. The distance measuring sensor 5 detects the distance from the arm portion 202 provided on the body assisting tool 200.

The distance measuring sensor 5 includes, for example, an infrared signal light emitting element and a light receiving element, and detects the voltage value of the signal received by the light receiving element after the infrared signal emitted from the light emitting element is reflected by the arm portion 202. The larger the detected voltage value, the shorter the distance, and the smaller the detected voltage value, the longer the distance. Further, if there is no reflecting object within a predetermined distance in the direction in which the infrared signal is transmitted, the voltage value is not detected. When the distance measuring sensor 5 is arranged at the position shown in FIG. 2, the voltage value is detected when the arm portion 202 is rotationally moved downward, and the voltage value is detected when the arm portion 202 is rotationally moved upward. It disappears. The distance measuring sensor 5 notifies the sensor control unit 4 of the presence / absence of detection of the voltage value.

The distance measuring method of the distance measuring sensor 5 shown here is only an example, and the present invention is not limited to the sensor that detects the distance by this method. For example, the sensor may be a type of sensor that measures the time until the infrared signal emitted from the light emitting element is reflected by the arm unit 202 and received by the light receiving element. Further, the present invention is not limited to the distance measuring method using an infrared signal.

The sensor control unit 4 detects whether the body assisting device 200 is in a used state or a non-used state, depending on whether or not a voltage value is detected by the distance measuring sensor 5. That is, the sensor control unit 4 indicates that the body assist device 200 is in the non-use state when the voltage value is not detected by the distance measuring sensor 5, and the body assist device 200 is in the use state when the voltage value is detected. To detect. Then, when the non-use state of the body assist device 200 is detected, a call is made to notify that the patient is about to leave the toilet seat 101.

However, there is no need to make a call when the nurse is assisting the patient to leave. On the other hand, when the patient is trying to leave the toilet seat 101 on his own when there is no nurse, it is necessary to make a call. Therefore, the sensor control unit 4 includes an operation unit 41 for instructing a setting regarding whether or not to execute a call, so that a nurse can set on / off of the call function by operating the operation unit 41. It has become.

That is, when the nurse assists the patient, the patient is seated on the toilet seat 101, the arm portion 202 is rotationally moved downward, and then the operation portion 41 is operated to set the calling function to ON. As a result, when the nurse comes out of the toilet and the patient tries to stand up by rotating the arm portion 202 upward after the end of the stool, the call is executed.

On the other hand, if the nurse goes out of the toilet after the call function is turned on as described above and the patient calls the nurse by operating the call button 6 after the stool is finished, the nurse operates first. Operate unit 41 to turn off the calling function. Then, the arm portion 202 is rotationally moved upward to assist the patient in moving away from the toilet seat 101. In this case, even if the non-use state of the body assist device 200 is detected, the call is not executed.

The operation unit 41 is installed at a position out of the reach of the patient seated on the toilet seat 101. In the example of FIG. 2, the operation unit 41 is provided on the wall surface at a position away from the toilet seat 101.

In addition, the sensor control unit 4 also executes control to display the on / off setting state of the calling function and the use / non-use state of the body assist device 200 on the display device 31 of the representative corridor light 3. That is, the sensor control unit 4 functions as a setting state confirmation device of the separation detection type nurse call system according to the present embodiment.

FIG. 3 is a block diagram showing a functional configuration example of the sensor control unit 4 according to the present embodiment. As shown in FIG. 3, the sensor control unit 4 of the present embodiment includes an operation reception unit 42, a state detection unit 43, an execution setting unit 44, a calling unit 45, and a display control unit 46 as its functional configuration.

For example, when configured by software, each of the functional blocks 42 to 46 is actually configured to include a computer CPU, RAM, ROM, etc., and is realized by operating a program stored in the RAM or ROM. The program may be stored in another recording medium such as a semiconductor memory.

The operation receiving unit 42 receives a user operation on the operation unit 41 for instructing a setting regarding whether or not to execute a call by the sensor control unit 4 (on / off of the calling function).

The state detection unit 43 detects whether the body assist device 200 is in the used state or not in the used state according to the position of the arm unit 202 provided on the body assist device 200 used by the patient seated on the toilet seat 101. As described above, the state detection unit 43 detects whether the body assisting device 200 is in the used state or the non-used state, depending on whether or not the voltage value is detected by the distance measuring sensor 5.

The execution setting unit 44 sets the call function on when the operation reception unit 42 receives a user operation on the operation unit 41 for setting the execution of the call to be present. On the other hand, the execution setting unit 44 sets the call function to off when the operation reception unit 42 receives a user operation on the operation unit 41 for setting no execution of the call. That is, each time the operation unit 41 is operated, the calling function can be alternately switched on / off for setting.

When the state detection unit 43 detects that the body assisting device 200 is not in use, the calling unit 45 is set to have the call executed (call function is on) by the execution setting unit 44. , Make a call.

The display control unit 46 displays the on / off state of the calling function set by the execution setting unit 44 and the use / non-use state of the body assist device 200 detected by the state detection unit 43 on the display device 31 of the representative corridor light 3. Display it. For example, the display control unit 46 displays the following four patterns.

The display of pattern (1) allows the nurse to confirm in the corridor that the patient in need of assistance is using the toilet. If the display of this pattern (1) continues for a long time, the nurse can detect that the patient may be left in the toilet.

The display of pattern (2) allows the nurse to confirm that the calling function may have been accidentally turned on in the hallway. In this case, if the patient who does not need assistance uses the physical aid 200 when using the toilet by himself / herself, an unnecessary call (false alarm) will be made. Therefore, the nurse who sees this display can operate the operation unit 41 to turn off the calling function.

The display of pattern (3) allows the nurse to accidentally turn off the calling function in the corridor even though the patient who does not need assistance is using the toilet or the patient who needs assistance is using the toilet. It can be confirmed that it may be. In the latter case, there is a possibility that the originally necessary call is not made (notification omission). Therefore, the nurse who sees this display can operate the operation unit 41 to turn on the calling function as needed by calling out from outside the toilet.

The display of pattern (4) allows the nurse to confirm that the toilet is not being used in the corridor. In this case, no particular action is required.

As described above, in the present embodiment, the on / off setting state of the calling function set according to the user operation for the operation unit 41 and the body assisting tool 200 used by the patient sitting on the toilet seat 101 are detected. The state of use / non-use is displayed on the display device 31 of the representative corridor light 3. As a result, the nurse can check the on / off setting state of the calling function and the use / non-use state of the physical aid 200 in the corridor outside the toilet, so that the calling function can be turned on / off. It is possible to easily confirm whether or not the off setting state and the 200 use / non-use state of the body assist device are appropriate.
