Description

  The present invention relates to a nurse call system that calls a medical worker such as a doctor or a nurse in response to a request from a patient in a hospital or the like.

  Conventionally, in a nurse call system, a nurse call cordless handset installed in the vicinity of a patient in a hospital room (for example, in the vicinity of a bed) and a nurse call master unit installed in a room for a medical worker (for example, a staff room). Are connected by wire.

  The nurse call slave unit and the nurse call master unit are connected via a corridor lamp installed near the entrance of each hospital room. The corridor lamp is installed near the entrance of each hospital room, and a plurality of nurse call cordless handsets are connected through a wall unit installed on the wall surface of the bedside. The wall unit has an outlet for connecting a nurse call slave such as a hand slave with a call function or a hand-push button slave. In the nurse call system in which the nurse call slave unit and the nurse call master unit are connected by a communication line for digital communication, the corridor lamp and the wall unit are wired by a communication line for digital communication of communication signals. . Here, the communication signal is a call signal for the nurse call slave unit to call the medical staff by the nurse call master unit, or the patient and the medical worker call between the nurse call slave unit and the nurse call master unit. A call signal for making a call. Digital communication is a communication signal transmitted with a code of “1” or “0”. The sign “1” or “0” is transmitted in the form of pulses of an electrical signal. In addition, by performing digital communication between the nurse call slave unit and the nurse call master unit, the source device transmits the communication signal to the destination without degradation, compared to analog communication that transmits the communication signal as it is. Can be sent to the device.

  In such a nurse call system, when a power line such as AC100V is wired near the communication line between the corridor lamp and the wall unit, noise pulses generated by the power line are generated between the corridor lamp and the wall unit. It was transmitted to the communication line. When a noise pulse is transmitted to the communication line, the communication line is affected by the noise pulse, and the amplitude of the pulse of the communication signal may be greatly disturbed. If the amplitude of the pulse of the communication signal is greatly disturbed, the pulse shape will be different from the original pulse shape of the communication signal. The patient cannot call the health care worker without a signal being sent from the wall unit to the corridor light, or the patient and the health care worker call without a call signal being communicated between the wall unit and the corridor light. Phenomenon that could not be done). Therefore, in order to increase the reliability of the nurse call system, nurse call system managers and the like must regularly check whether noise pulses are transmitted to the communication line between the corridor lamp and the wall unit. was there.

Incidentally, an image forming apparatus having a function of detecting a noise pulse by a receiving antenna that receives a signal from a wireless tag is known (see, for example, Patent Document 1). In the image forming apparatus described in Patent Document 1, the noise level in the vicinity of the image forming apparatus is detected by counting noise pulses included in the external noise received by the receiving antenna. Thereby, the administrator of the image forming apparatus can check whether or not external noise is generated in the vicinity of the image forming apparatus.
JP 2006-3374 A

  However, when the noise pulse detection method of the image forming apparatus described in Patent Document 1 is applied to a nurse call system, the image forming apparatus described in Patent Document 1 receives radio waves scattered in the vicinity of the image forming apparatus. Since the signal is received by the antenna, the noise pulse transmitted to the communication line cannot be detected when the corridor lamp and the nurse call cordless handset are connected by a wire such as a communication line. For this reason, there has been a problem that noise pulses transmitted to the communication line connecting the corridor lamp and the nurse call slave cannot be accurately detected.

  The present invention has been made to solve such problems, and a nurse call system administrator or the like accurately detects noise pulses transmitted to a communication line connecting a nurse call cordless handset and a corridor lamp. The purpose is to be able to grasp.

  In order to solve the above-described problem, in the present invention, when an inspection start operation unit is operated, a slave unit control unit that controls a nurse call slave unit and an external device control unit that controls an external device including a corridor lamp The first communication signal and the third communication signal are prevented from being output to the communication line. At this time, the detection unit detects a pulse that is a second communication signal received by the external device reception unit via the communication line, and the external device control unit outputs information indicating the detection result. ing.

  According to the present invention configured as described above, the second communication received via the communication line in a state where the first communication signal and the third communication signal are not output from the nurse call cordless handset and the corridor lamp. When a pulse that is a signal is detected, the signal is regarded as noise. As a result, a signal that cannot be received via the communication line is determined not to affect the communication line, and the second communication signal received via the communication line is determined to affect the communication line. Is done. Therefore, a nurse call system administrator or the like can accurately grasp the noise pulse transmitted to the communication line connecting the nurse call slave unit and the corridor lamp.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A block diagram of the nurse call system according to this embodiment is shown in FIG.

The corridor lamp transmitter 34 transmits the call signal received by the corridor lamp receiver 33 to the nurse call slave device 10 via the communication line 50.

  As described above, when the corridor lamp control unit 31 determines that the inspection start operation unit 35 is operated in a state where the first communication signal and the third communication signal can be transmitted to the communication line 50. The corridor lamp control unit 31 switches the operation mode of the corridor lamp 30 from the normal mode to the inspection mode. At the same time, the corridor lamp control unit 31 generates an inspection start signal indicating that the inspection of the communication line 50 is started. Then, the corridor lamp transmitter 34 transmits the inspection start signal generated by the corridor lamp controller 31 to the nurse call slave 10 via the communication line 50. The corridor lamp transmitting unit 34 transmits the inspection start signal generated by the corridor lamp control unit 31 to the nurse call parent device 40.

  On the other hand, if the operation mode of the corridor lamp 30 is the inspection mode and the first communication signal and the third communication signal are not output to the communication line 50, the corridor lamp is operated when the inspection end operation unit 37 is operated. If the control unit 31 determines, the corridor lamp control unit 31 switches the operation mode of the corridor lamp 30 from the inspection mode to the normal mode. At the same time, the corridor lamp control unit 31 generates an inspection end signal indicating that the inspection of the communication line 50 has ended. Then, the corridor lamp transmitter 34 transmits the inspection end signal generated by the corridor lamp controller 31 to the nurse call slave 10 via the communication line 50. The corridor lamp transmission unit 34 transmits the inspection end signal generated by the corridor lamp control unit 31 to the nurse call parent device 40.

  The base unit control unit 41 controls each component of the nurse call base unit 40 as described later. The master unit I / F unit 42 is connected to the corridor lamp I / F unit 32 so that the nurse call master unit 40 communicates with the corridor lamp 30.

And transmitted to the nurse call slave unit 10 via the communication line 50.

  The base unit determination unit 47 determines whether or not the base unit receiving unit 43 has received the inspection start signal transmitted from the corridor lamp 30, and uses the inspection end signal transmitted from the corridor lamp 30 for the base unit. It is determined whether the receiving unit 43 has received it.

  When a call operation is performed by a medical worker in a state where the operation mode of the nurse call parent device 40 is the normal mode, the parent device transmission unit 46 generates the call signal generation unit 44 for the parent device. The call signal is transmitted to the nurse call handset 10 via the corridor lamp 30 and the communication line 50. When a call path is formed between the nurse call parent device 40 and the nurse call child device 10, the parent device transmission unit 46 correlates the call signal generated by the parent device call signal generation unit 45 with the corridor. It is transmitted to the nurse call slave unit 10 through the lamp 30 and the communication line 50. Thus, in the state in which the third communication signal can be transmitted to the communication line 50, the inspection start operation unit 35 is operated and the main unit reception unit 43 receives the inspection start signal transmitted from the corridor lamp 30. When the base unit determination unit 47 determines that the call has been received, the base unit control unit 41 switches the operation mode of the nurse call base unit 40 from the normal mode to the inspection mode. At the same time, the base unit control unit 41 stops the operations of the base unit call signal generation unit 44 and the base unit call signal generation unit 45 so that the third communication signal is not transmitted to the outside. As a result, the third communication signal is not output to the communication line 50.

  In addition, when the operation mode of the nurse call parent device 40 is the normal mode, the inspection end operation unit 37 is operated, and the inspection end signal transmitted from the corridor lamp 30 is received by the main unit receiving unit 43. When the parent device determination unit 47 determines, the parent device control unit 41 keeps the operation mode of the nurse call parent device 40 in the normal mode.

  On the other hand, in the state where the operation mode of the nurse call parent device 40 is the inspection mode and the third communication signal is not output to the communication line 50, the inspection end operation unit 37 is operated and transmitted from the corridor lamp 30. When the master unit determination unit 47 determines that the master unit receiving unit 43 has received the inspection end signal, the master unit control unit 41 operates the nurse call master unit 40 from the inspection mode to the normal mode. Switch modes. At the same time, the base unit control unit 41 cancels the stop of the operations of the base unit call signal generation unit 44 and the base unit call signal generation unit 45 so that the third communication signal is transmitted to the outside. To. As a result, the third communication signal is output to the communication line 50.

  In addition, when the operation mode of the nurse call master unit 40 is the inspection mode, the inspection start operation unit 35 is operated and the inspection unit start signal transmitted from the corridor lamp 30 is received by the main unit reception unit 43. When the parent device determination unit 47 determines, the parent device control unit 41 keeps the operation mode of the nurse call parent device 40 in the inspection mode.

  Next, the operation of the nurse call system according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of the display unit of the corridor lamp 30 of the nurse call system according to the present embodiment. In the nurse call system in which the operation mode is the normal mode, the corridor lamp control unit 31 divides the display screen 380 according to the arrangement of the bed in the hospital room where the corridor lamp 30 is installed, and the patient is displayed in the divided display area. And the child device number of the nurse call child device 10 used by the patient are respectively displayed. Moreover, the inspection start operation part 35 is each displayed on the divided display area. Further, since the display screen 380 is configured by a touch panel display, when the display area of the inspection start operation unit 35 is touched, the corridor lamp control unit 31 performs the inspection start operation corresponding to the coordinates of the touched position. The operation of the unit 35 is performed.

  When the patient in the hospital room where the corridor lamp 30 is installed performs a call operation in the state where the operation mode is the normal mode, the handset call signal generation unit 12 generates a call signal. The slave unit transmitter 14 transmits the call signal generated by the slave unit call signal generator 12 via the slave unit I / F unit 16. The corridor lamp receiving unit 33 receives the call signal via the corridor lamp I / F unit 32. The corridor lamp control unit 31 notifies the call by turning on or blinking the display lamp 381. On the other hand, the corridor lamp transmitter 34 transmits the received call signal to the nurse call parent device 40 via the corridor lamp I / F unit 32.

  The base unit receiving unit 43 receives the calling signal via the base unit I / F unit 42. The base unit control unit 41 outputs a calling notification sound through a speaker (not shown). In this state, when a handset (not shown) provided in the nurse call parent device 40 is off-hooked, the parent device control unit 41 makes a call between the nurse call parent device 40 and the nurse call child device 10. Form a road. When the call path is formed, the call signal generated by the call signal generation unit 13 for the child device is transmitted to the nurse call parent device 40 in the same manner as the call signal. Here, base unit control unit 41 outputs a voice based on the call signal received by base unit receiving unit 43 from a handset or the like. On the other hand, a call signal (such as a voice of a medical worker input by a handset) generated by the call signal generator 45 for the parent device is transmitted from the nurse call parent device 40 to the nurse call child device 10.

  When calling the nurse call slave unit 10 from the nurse call master unit 40, the operation reverse to the above-described operation may be performed. However, when calling a specific patient, the medical worker calls the patient to be called to the nurse call master unit 40. It is necessary to select with. Further, there is no need to notify the call by the hallway light 30.

  Thus, when the nurse call parent device 40 is called from the nurse call child device 10 or when the nurse call child device 10 is called from the nurse call parent device 40, the first communication signal is the nurse call child device. 10 is transmitted to the nurse call parent device 40 via the communication line 50 and the hall light 30, and the third communication signal is transmitted from the nurse call parent device 40 to the nurse call child device 10 via the hall light 30 and the communication line 50. Is done.

  As described above, in the state where the operation mode is the normal mode, the corridor lamp control unit 31 determines whether or not the inspection start operation unit 35 has been operated by a nurse call system administrator or the like. When the corridor lamp control unit 31 determines that the inspection start operation unit 35 has been operated, the corridor lamp control unit 31 switches the operation mode of the corridor lamp 30 from the normal mode to the inspection mode. At the same time, the corridor lamp control unit 31 generates an inspection start signal. Then, the corridor lamp transmission unit 34 starts the inspection generated by the corridor lamp control unit 31 for the nurse call slave unit 10 of the slave unit number corresponding to the display area where the inspection start operation unit 35 is operated. The signal is transmitted through the corridor lamp I / F unit 32. The corridor lamp transmitter 34 transmits the inspection start signal generated by the corridor lamp controller 31 to the nurse call parent device 40 via the corridor lamp I / F unit 32.

  In the state where the operation mode is the normal mode, the slave unit determination unit 17 of the nurse call slave unit 10 determines whether the slave unit reception unit 15 has received the inspection start signal. When the slave unit determination unit 17 determines that the slave unit receiver 15 has received the inspection start signal, the slave unit controller 11 switches the operation mode of the nurse call slave unit 10 from the normal mode to the check mode. Switch. Further, the base unit determination unit 47 of the nurse call base unit 40 determines whether or not the base unit reception unit 43 has received an inspection start signal. When the base unit determination unit 47 determines that the base unit receiving unit 43 has received the inspection start signal, the base unit control unit 41 switches the operation mode of the nurse call base unit 40 from the normal mode to the inspection mode. Switch.

  In the state where the operation mode is switched to the inspection mode, the slave unit control unit 11 stops the operation of the slave unit call signal generation unit 12, so that the slave unit call signal generation unit 12 causes the call signal to be Cannot be generated. The slave unit control unit 11 stops the operation of the slave unit call signal generation unit 13 so that the slave unit call signal generation unit 13 cannot generate a call signal. As a result, the first communication signal is not output to the communication line 50.

  In addition, when the operation mode is the inspection mode, the base unit control unit 41 stops the operation of the base unit call signal generation unit 44 so that the base unit call signal generation unit 44 outputs the call signal. Disable generation. The base unit control unit 41 stops the operation of the base unit call signal generation unit 45 so that the base unit call signal generation unit 45 cannot generate a call signal. As a result, the third communication signal is not output to the communication line 50 via the corridor lamp 30.

  In addition, the corridor lamp control unit 31 operates the detection unit 36 in a state where the operation mode is the inspection mode. In the state where the first communication signal from the nurse call slave unit 10 and the third communication signal from the nurse call parent unit 40 are not transmitted to the communication line 50, the detection unit 36 communicates with the corridor lamp reception unit 33. A pulse that is a second communication signal received from the line 50 is detected. The corridor lamp control unit 31 determines the presence or absence of noise from the detection result information indicating whether or not the detection unit 36 has detected a pulse that is the second communication signal. Here, the corridor lamp control unit 31 determines that there is noise when the detection unit 36 detects a pulse that is the second communication signal.

  When the corridor lamp control unit 31 determines that there is noise, the corridor lamp control unit 31 has noise as well as the slave unit number of the nurse call slave unit 10 being inspected, as shown in FIG. Is displayed on the display screen 380. Specifically, the corridor lamp control unit 31 displays on the display screen 380 characters “during communication line inspection, slave unit number: 20101, noise present”. At the same time, the corridor lamp control unit 31 lights or blinks the display lamp 381. Here, the corridor lamp control unit 31 lights or blinks the display lamp 381 when the call is made by the nurse call handset 10, and turns on or blinks the display lamp 381 when there is noise in the communication line 50. It is preferable to make the pattern blinking different. The corridor lamp control unit 31 displays the inspection end operation unit 37 on the display screen 380. Since the display screen 380 is constituted by a touch panel display as described above, when the display area of the inspection end operation unit 37 is touched, the corridor lamp control unit 31 corresponds to the coordinates of the touched position. The operation of the inspection end operation unit 37 is performed.

  In the state where the operation mode is the inspection mode, the corridor lamp control unit 31 determines whether or not the inspection end operation unit 37 has been operated by a nurse call system administrator or the like. When the corridor lamp control unit 31 determines that the inspection end operation unit 37 has been operated, the corridor lamp control unit 31 switches the operation mode of the corridor lamp 30 from the inspection mode to the normal mode. At the same time, the corridor lamp control unit 31 generates an inspection end signal. Then, the corridor lamp transmitting unit 34 sends an inspection end signal generated by the corridor lamp control unit 31 to the nurse call slave device 10 that has been inspected via the corridor lamp I / F unit 32. Send. The corridor lamp transmitter 34 transmits the inspection end signal generated by the corridor lamp controller 31 to the nurse call parent device 40 via the corridor lamp I / F unit 32. Here, the corridor lamp control unit 31 returns the display screen 380 and the display lamp 381 to the original state (the state of FIG. 2A).

  On the other hand, in a state where the operation mode is the inspection mode, the slave unit determination unit 17 of the nurse call slave unit 10 determines whether or not the slave unit reception unit 15 has received the inspection end signal. When the slave unit determination unit 17 determines that the slave unit receiver 15 has received the inspection end signal, the slave unit controller 11 switches the operation mode of the nurse call slave unit 10 from the inspection mode to the normal mode. Switch. Then, the slave unit control unit 11 releases the stop of the operation of the slave unit call signal generation unit 12 so that the slave unit call signal generation unit 12 can generate a call signal. Further, the slave unit control unit 11 releases the stop of the operation of the slave unit call signal generation unit 13 so that the slave unit call signal generation unit 13 can generate a call signal. As a result, the first communication signal is output to the communication line 50.

  Further, the base unit determination unit 47 of the nurse call base unit 40 determines whether or not the base unit reception unit 43 has received an inspection end signal. If the base unit determination unit 47 determines that the base unit receiving unit 43 has received the inspection end signal, the base unit control unit 41 changes the operation mode of the nurse call base unit 40 from the inspection mode to the normal mode. Switch. The base unit control unit 41 releases the stop of the operation of the base unit call signal generation unit 44 so that the base unit call signal generation unit 44 can generate a call signal. Further, the base unit control unit 41 releases the stop of the operation of the base unit call signal generation unit 45 so that the base unit call signal generation unit 45 can generate a call signal. As a result, the third communication signal is output to the communication line 50 via the corridor lamp 30.

  As described above in detail, in the nurse call system according to the present embodiment, the slave unit controller 11 that controls the nurse call slave unit 10 in the inspection mode is configured so that the first communication signal is not output to the communication line 50. Yes. Further, the base unit controller 41 that controls the nurse call base unit 40 prevents the third communication signal from being output to the communication line 50. At this time, the detection unit 36 detects a pulse that is a second communication signal received by the hall light reception unit 33 via the communication line 50. When the detection unit 36 detects a pulse that is the second communication signal, the corridor lamp control unit 31 determines that noise is transmitted to the communication line 50. Thereby, when the second communication signal received via the communication line 50 is detected in a state where the first communication signal and the third communication signal are not output to the communication line 50, the signal is regarded as noise. Considered. As a result, a signal that cannot be received via the communication line 50 is determined not to affect the communication line 50, and the second communication signal received via the communication line 50 has an influence on the communication line 50. It is determined to give. Therefore, a nurse call system administrator or the like can accurately grasp the noise pulse transmitted to the communication line 50 connecting the nurse call slave unit 10 and the corridor lamp 30. When a nurse call system administrator knows that the noise pulse is transmitted to the communication line 50, the power line wired near the communication line 50 is moved to a position where the communication line 50 is not affected. The noise pulse can be prevented from being transmitted to the communication line 50 by moving the communication line 50 to a position that does not affect the power line. Therefore, it is possible to make it difficult for a communication failure to occur between the corridor lamp 30 and the nurse call slave device 10. In addition, it is possible to easily find the cause of the communication failure that occurs between the corridor lamp 30 and the nurse call slave device 10.

  In the above-described embodiment, when the nurse call handset 10 receives the inspection start signal, the handset controller 11 stops the first communication signal generation process, and the first communication signal is transmitted through the communication line. However, the present invention is not limited to this. For example, when the nurse call handset 10 receives an inspection start signal, the handset controller 11 may control the handset transmitter 14 to stop the transmission process of the first communication signal. Moreover, you may make it the subunit | mobile_unit control part 11 stop both the production | generation process of a 1st communication signal, and the transmission process of a 1st communication signal.

  In the embodiment described above, when the nurse call parent device 40 receives the inspection start signal, the parent device control unit 41 stops the third communication signal generation process, and the third communication signal is transmitted to the communication line. However, the present invention is not limited to this. For example, when the nurse call parent device 40 receives an inspection start signal, the parent device control unit 41 may control the parent device transmission unit 46 to stop the transmission process of the third communication signal. The base unit control unit 41 may stop both the third communication signal generation process and the third communication signal transmission process.

  In the present modification, when the nurse call parent device 40 receives the inspection start signal, the parent device control unit 41 stops generating the third communication signal, and the third communication signal is transmitted to the communication line 50. However, the present invention is not limited to this. For example, when the corridor lamp 30 transmits an inspection start signal, the corridor lamp controller 31 may control the corridor lamp transmitter 34 to stop the transmission processing of the third communication signal.

  In the above-described embodiment, when the operation mode is the inspection mode, the corridor lamp control unit 31 displays the inspection result of one communication line 50 on the display screen 380. It is not limited. For example, the corridor lamp control unit 31 may simultaneously display the inspection results of all the communication lines 50 connected to the corridor lamp 30 on the display screen 380.

  In the above-described embodiment, the display screen 380 is provided with the inspection start operation unit 35 in an area where the display screen 380 is divided for each patient. However, the present invention is not limited to this. For example, the display screen 380 may be provided with only one inspection start operation unit 35 on the display screen 380. Thereby, all the communication lines 50 connected to the corridor lamp 30 in which the inspection start operation unit 50 is operated can be inspected at the same time.

  In the above-described embodiment, the corridor lamp 30 includes the inspection start operation unit 35, the detection unit 36, the inspection end operation unit 37, and the display unit 38, but is not limited thereto. For example, the nurse call parent device 40 may be provided with an inspection start operation unit, a detection unit, an inspection end operation unit, and a display unit.

  In the above-described embodiment, the corridor lamp control unit 31 lights or blinks the display lamp 381 when there is noise regardless of the number of pulses detected by the detection unit 36. It is not limited. For example, the corridor lamp control unit 31 may change the pattern for lighting or blinking the display lamp 381 for each number of pulses detected by the detection unit 36. Specifically, a nurse call system administrator or the like presets a range of the number of pulses and a pattern for turning on or blinking the display lamp 381 by a corridor lamp setting unit (not shown). The detection unit 36 counts the number of detected pulses and outputs the counted number of pulses to the corridor lamp control unit 31 as detection result information. Then, the corridor lamp control unit 31 acquires a pattern set in a range corresponding to the number of pulses indicated by the detection result information from the corridor lamp setting unit, and turns on the display lamp 381 based on the acquired pattern. It is made to blink. Here, the pattern for lighting or blinking the display lamp 381 includes the brightness and color of the display lamp 381, the blinking interval, and the like.

  Moreover, in embodiment mentioned above, when the operation mode is inspection mode, although the control part 11 for subunit | mobile_units has invalidated calling operation, it is not limited to this. For example, when a medical worker uses the nurse call handset 10 to make an emergency call for calling another medical worker, such as when the patient's condition changes suddenly, the handset controller 11 calls the handset. You may make it validate operation. Thereby, even if the communication line 50 is under inspection, the medical worker can make an emergency call.

  In the above-described embodiment, the corridor lamp control unit 31 displays the presence / absence of a pulse corresponding to the detection result information output from the detection unit 36 on the display screen 380, but is not limited thereto. For example, the corridor lamp control unit 31 may display a waveform diagram of pulses detected by the detection unit 36 on the display screen 380 '. Specifically, as shown in FIG. 3, the corridor lamp control unit 31 includes, for example, a letter “pulses detected by the detection unit 36 and a character“ in the communication line check, slave unit number: 20101, with noise ” Is displayed on the display screen 380 ′. Further, the nurse call system administrator or the like can confirm the influence of noise on the communication line 50 based on the size of the waveform shown in the pulse waveform diagram.
