Description

  The present invention relates to a nurse call system, and more particularly to a nurse call system including a display for displaying patient information on a corridor lamp that notifies a call from a patient.

  The nurse call system responds to the call from the nurse call cordless handset installed in each bed to call the nurse, the corridor lamp that informs the call from the nurse call call cordless handset in front of the hospital room, It consists of a nurse call master unit for controlling the system and a controller for controlling the system. In such a nurse call system, there is one in which a hallway lamp is provided with a display for displaying patient information such as the name of a hospitalized patient in a hospital room and a relief category.

For example, in Patent Document 1, a hallway lamp is provided with a liquid crystal display to display patient information. A human sensor is provided so that patient information is not displayed in the stand-by state so that the patient information is not displayed. However, when the human sensor detects the approach of a nurse or the like, the backlight is activated to display an animal picture or the like. The patient information is displayed by, for example, pressing and holding the recovery button.
Japanese Patent Laid-Open No. 2006-21029

In the case of a corridor lamp, since it is not preferable to increase the number of operation buttons, one button is made multifunctional, and the patient information is displayed by operating the recovery button for a long time as shown in Patent Document 1 above. Therefore, it is not suitable for a case where the operability is lowered and a speedy response is required. Also, it was difficult to operate when both hands were closed.
On the other hand, because the amount of data that can be displayed at once on the corridor lamp liquid crystal display is limited, it is necessary to perform an operation of switching the display contents when a large amount of information is to be displayed. It is difficult to provide an operation button, and there is a problem that an existing button has to be further multifunctional. When a large amount of information is displayed, the problem of operability becomes more serious.

  Therefore, in view of such problems, the present invention has an object to provide a nurse call system that can switch display contents of a corridor lamp with a simple operation without providing a dedicated switch on the corridor lamp.

In order to solve the above-mentioned problems, the invention of claim 1 is directed to a nurse call slave set installed for each bed for calling a nurse, a call from the nurse call slave set and an image display of patient information. In a nurse call system having a corridor lamp equipped with a display and a nurse call master unit installed in a nurse station for answering a call from the nurse call cordless handset, the corridor lamp is a sensor for switching the display on the display. The sensor has two levels of sensitivity: a first sensitivity for detecting the approach of a person and a second sensitivity for detecting a proximity motion such as a hand being touched. When receiving the sensor, the sensor is in the first sensitivity state, and has sensor sensitivity control means for switching to the second sensitivity when the approach of a person is detected. Switching from the standby state to the display of the predetermined first screen Isupurei, characterized by having a display control means for performing control to switch the display of the predetermined second screen when detecting operation in the second sensitivity.
With this configuration, when the person approaches due to the first sensitivity state, the display is switched from the standby state to a screen that displays the patient name in the patient information, for example, and the proximity such that the hand is touched by the second sensitivity. For example, since the display switching operation is performed in two stages so as to display all of the patient information by detecting the operation, the display can be switched without providing a button for switching the display screen. Therefore, patient information can be viewed with a simple operation, and since no button operation is required, the patient information can be displayed even when the hand is closed.

According to a second aspect of the present invention, in the first aspect of the invention, the sensor sensitivity control means sets the first sensitivity when a predetermined time elapses without performing the detection operation in a state where the sensor is switched to the second sensitivity. In addition to switching, the display control means returns from the display of the first screen to the standby state when no detection operation is performed with the first sensitivity.
With this configuration, even if the sensitivity of the sensor is at the second sensitivity, if the detection operation is not performed for a certain period of time, the first sensitivity is restored, so that the approach of a person can be continuously detected. Further, since the display on the display automatically returns to the standby state, there is no need to keep displaying patient information and the like, and there is no need to turn off the display.

According to a third aspect of the present invention, in the first or second aspect of the present invention, if the sensor is not sensing for the first predetermined time in a state where the display is switched to the display of the second screen, the sensor sensitivity control means Switches the sensor to the first sensitivity, and the display control means switches the display to the display of the first screen, and if the sensor does not continue to detect at the first sensitivity for the second predetermined time, the display control means It is characterized by returning to the standby state from the display of the first screen.
With this configuration, even if the display displays the second screen, the display is turned off after a certain period of time (becomes a standby state), and the sensor returns to the first sensitivity, so that no reset operation is required.

According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, when the sensor is in the second sensitivity state, the display control means detects the second screen only while detecting a human approaching action. It is characterized by switching to the display.
With this configuration, the second screen is displayed only during the display operation, and is not continuously displayed even when a nurse or the like leaves the corridor lamp, and a third person looks at the second screen. There is no.

According to a fifth aspect of the present invention, in the invention according to any one of the first to third aspects, when the display is in the display state of the second screen, if the sensor maintaining the second sensitivity performs a detection operation, the display The control means switches the display on the display to the display on the first screen.
With this configuration, in addition to turning on the second screen, the off operation is also performed by moving the hand, etc., so the second screen can be easily turned off.

  According to the present invention, when a person approaches due to the first sensitivity state, the display is switched from the standby state to a screen for displaying the patient name in the patient information, for example, and the hand is touched by the second sensitivity. Since the two-stage display switching operation is performed so as to display all of the patient information by detecting the proximity operation, display switching can be performed without providing a button for switching the display screen. Therefore, patient information can be viewed with a simple operation, and since no button operation is required, the patient information can be displayed even when the hand is closed.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an example of a nurse call system according to the present invention. 1 is a nurse call slave unit (call button 1a and slave unit plate 1b) that is installed for each bed and calls a nurse. Is a corridor lamp that is installed near the entrance of the hospital room and notifies a call from the nurse call child device 1, and 3 indicates a nurse call parent device for responding to the call from the nurse call child device 1. The corridor lamp 2 and the nurse call slave unit 1 are connected by, for example, two signal lines L1, and the corridor lamp 2 and the nurse call master unit 3 are connected by, for example, two signal lines L2, and A1 and A2 are A hospital room is shown, and B is a nurse station.
Each corridor lamp 2 is connected with 1 to 6 nurse call slave units 1, and the nurse call master unit 3 is connected with 1 to 60 corridor lamps.

  FIG. 2 shows a circuit block diagram of the slave unit plate 1b, the corridor lamp 2, and the nurse call master unit 3. As shown in this figure, the slave unit plate 1b includes a call button connection terminal 11, a slave unit CPU 12 for controlling the nurse call slave unit 1, a data transmission / reception circuit 13 for communicating with the corridor lamp 2, and a microphone. 14, a speaker 15, a loudspeaker amplifier 16, an indicator lamp 17 for displaying a call, and an A / D conversion circuit 18 for A / D converting a call voice.

  The corridor lamp 2 communicates with a display 21 composed of, for example, a liquid crystal display for displaying patient information, a human sensor 22 for detecting the approach of a person, a corridor lamp CPU 23 for controlling the corridor lamp 2, and a nurse call master 3. A first data transmission / reception circuit 24, an indicator lamp 25 for displaying a call, a memory 26 for storing patient information, a sensitivity switching circuit 27 for switching the sensitivity of the human sensor 22, and the nurse call slave 1 A second data transmission / reception circuit 28 and a timer 29 are provided.

  The human sensor 22 is configured to be switched between a high sensitivity first sensitivity state and a low sensitivity second sensitivity state, and detects the approach of a person from a distance in the first sensitivity state. In the sensitivity state, it is configured to detect a proximity action of a person such as a hand holding the human sensor 22. This switching control is performed by the corridor lamp CPU 23 as sensor sensitivity control means. The patient information stored in the memory 26 is transmitted from the nurse call parent device 3 by the operation of the nurse call parent device 3 and stored.

  The nurse call base unit 3 includes a handset 31 for making a call, an A / D conversion circuit 32 for A / D converting the call voice, a base unit CPU 33 for controlling the nurse call base unit 3, and a corridor lamp 2. A data transmission / reception circuit 34 is provided for communication.

  Next, the operation of the nurse call system configured as described above will be described. However, since the call operation from the nurse call slave unit 1, the response operation from the nurse call master unit 3 to the call, and the call notification operation of the corridor lamp 2 are the same as those in the conventional system, the explanation is omitted here. The display operation of the display 21 of the corridor lamp 2 which is the main part of the present invention will be described.

FIG. 3 shows the flow of the display display operation of the corridor lamp 2, and will be described according to this flow. At the time of standby, the display 21 of the corridor lamp 2 is turned off (S1), and the detection sensitivity of the human sensor 22 is set to high sensitivity (first sensitivity) (S2). Therefore, if there is a person approaching the corridor lamp 2 from a distance, it is detected (S3). The corridor lamp CPU 23 as display control means activates the display 21 when the human sensor 22 detects an approaching person, and displays only the patient name among the patient information stored in the memory 26 as the display of the first screen. (S4) At the same time, the sensitivity switching circuit 27 is controlled to set the sensitivity of the human sensor 22 to low sensitivity (second sensitivity) (S5), the timer 29 is set, and the first predetermined time is counted (S6).
In this state, when a nurse or the like approaching before the first predetermined time elapses performs a proximity operation such as placing a hand on the human sensor 22, the human sensor detects this (S7). Upon receiving this detection signal, the corridor lamp CPU 23 displays all patient information such as the patient's disease name, nursing history, and call history on the display 21 as the second screen display (S13).

  However, the human sensor 22 in the second sensitivity state returns to the first sensitivity (S9) when the first predetermined time (for example, 20 seconds) has elapsed (S8) without performing the detection operation, and the first sensitivity Continue to display the screen (S4). Then, the timer 29 is set to about 0.5 seconds shorter than the set time of the timer set of S6 or the timer set of S14 (S10), the second predetermined time is counted, and when the set time has passed (S12) the display 21 Is turned off to return to the standby state (S1).

  On the other hand, when all the patient information is displayed (S13), the timer 29 is set (S14) and the counting of the third predetermined time is started. In the meantime, the human sensor 22 maintains the second sensitivity and continues to display when detecting a motion such as a hand again (S15), and when a third predetermined time such as 5 seconds elapses (S16). Returning to the first screen display (S4), once the first and second predetermined times have elapsed, the display is turned off and the standby state (S1) is restored.

In this way, when the person approaches due to the first sensitivity state, the display is switched from the standby state to a screen displaying the patient's name in the patient information, and the proximity operation such as a hand is touched according to the second sensitivity. Since the display switching operation in two stages for displaying all of the patient information is performed, display switching can be performed without providing a button for switching the display screen. Therefore, patient information can be viewed with a simple operation, and since no button operation is required, the patient information can be displayed even when the hand is closed.
Even if the sensitivity of the sensor is at the second sensitivity, if the detection operation is not performed for a certain period of time, the sensor returns to the first sensitivity, so that it is possible to continue detecting human approach. Further, since the display on the display automatically returns to the standby state, there is no need to keep displaying patient information and the like, and there is no need to turn off the display.
Furthermore, even if the display is on the second screen, after a certain time has elapsed, the display returns to the first screen and then turns off (becomes a standby state), and the human sensor returns to the first sensitivity. No reset operation is required.
Moreover, since two sensors are made to perform two-step detection operation without providing two sensors, it can be configured at low cost.

FIG. 4 shows another form of the display operation of the display 21. Since the operation from the standby state to the step (S13) for displaying detailed patient information is the same as that in FIG. 3, the description is omitted, and the next step (S21) will be described. Here, the corridor lamp CPU 23 displays the second screen (S13) only while the proximity movement such as a hand is detected (S21). If not detected, that is, if the approaching nurse or the like stops crawling, the display returns to the first screen (S4).
Thereafter, the operation is the same as the operation shown in FIG. 3. If the human sensor 22 does not perform the detection operation, the process returns to the standby state (S1) after a predetermined time has elapsed. Display (S13).
As described above, the detailed display is only performed during the display operation, and is not continuously displayed even when a nurse or the like leaves the corridor lamp, and the third person does not see the second screen.

FIG. 5 shows still another form of the display operation of the display 21. Since the operation from the standby state to the step (S13) for displaying detailed patient information (second screen) is the same as that in FIG. 3, description thereof will be omitted, and description will be made from the next step (S31). Here, the display of the second screen is continued until the human sensor 22 detects again.
When the second screen is displayed (S13), the timer is set (S31) and starts counting the fourth predetermined time, and the human sensor 22 in the second sensitivity state approaches during this set time. When the proximity movement of the person is detected (S32), the display is returned to the display of only the patient name (S4) which is the first screen. If the proximity operation is not detected and, for example, a fourth predetermined time of 30 seconds has elapsed (S33), the display 21 is turned off and returns to the standby state (S1).
As described above, since the detail display operation is performed by a movement such as depressing the hand in addition to the on operation, the detail display screen can be easily turned off.

In the above embodiment, the display 21 is turned off in the standby state, but a picture or the like that is not related to the patient information may be displayed. In addition, only the name of the patient information is displayed as the first screen, and detailed patient information is displayed as the second screen. However, a picture not related to the patient information is displayed as the first screen. Detailed patient information including the patient name may be displayed.
Further, although there is one nurse call master unit 3, a plurality of nurse call master units 3 or a portable master unit may be provided. Further, a controller for controlling the communication path may be installed in the middle of the line L2.
