Description

  The present invention relates to an emergency call system for notifying other staff members when a staff member such as a medical worker in a facility such as a hospital is in a dangerous state.

  Doctors and nurses who work in hospitals and other facilities (hereinafter collectively referred to as medical workers) often face patients and their families in hospital rooms and conference rooms. In such a case, the patient may be dissatisfied with the medical staff's response to themselves or the hospital's response to themselves. Similarly, the patient's family may be dissatisfied with the medical staff's response to the patient and hospital response. For this reason, patients and their families are increasingly using violence or rants to health care workers.

By the way, in order to suppress the occurrence of violence against children in facilities such as schools, a notification system is known that allows a child to have a portable transmission device to operate in the event of an emergency ( For example, Patent Document 1).
JP 2003-109163 A

  If the report system described in Patent Document 1 is applied to a hospital or the like so that a medical worker has a portable transmission device, the medical worker is exposed to violence or abuse. It is possible to request support from other medical professionals. However, when the reporting system of Patent Document 1 is applied to a hospital, support can be requested, but what was the situation at the site (how did the health care worker report)? Is not recorded. Therefore, what is actually being done at the site is left to the testimony of medical staff, patients, and the patient's family, making it difficult for the hospital to investigate the truth. was there.

On the other hand, when the volume level input to the ceiling microphone provided in the hospital room is higher than a predetermined level, a communication path is formed between the nurse center where the medical staff is present and the patient room where the patient is present, There is known a nurse call device that listens to the sound at a nurse center (for example, Patent Document 2).
JP 2001-127893 A

  By recording the voice in the hospital room acquired using the nurse call device described in Patent Document 2, it is possible to record the situation at the site where the health care worker reported. . However, in order to record what was actually performed in the hospital room at the site, it is necessary for medical staff to record before making a report. There is a problem that it is necessary to always form a communication path between them, which violates patient privacy.

  In addition, even if the problem of infringing on patient privacy is ignored, the place where health care workers are violated or abused is not limited to a specific room, so between the nurse center and all rooms. A call path must always be formed. However, the current nurse call device has a problem that it cannot cope with such recording because the communication path between the nurse center and the hospital room can only form several lines at the same time. Further, if the communication path is always formed, it is an original function of the nurse call device, and there is a problem that the patient cannot call the medical staff.

  The present invention has been made to solve such a problem, and while making the best use of the function of the nurse call device while protecting the privacy of the patient as much as possible, the present nurse call device is used to make a report. The purpose is to be able to record appropriately what kind of situation the health care worker was.

  In order to solve the above-described problems, in the present invention, when a call signal is transmitted by an operation of a portable transmission device carried by a medical worker, it is installed at various locations in a hospital with the installation position specified. The receiving receiver receives the calling signal and measures the reception level to identify the installation position of the receiver having the highest reception level. On the other hand, the nurse call handset always records the latest situation in the surrounding area over a predetermined time. Then, the nurse call master unit connects a line with a nurse call slave unit installed in the vicinity of the installation position of the receiver, and acquires information recorded by the nurse call slave unit.

  According to the present invention configured as described above, the information recorded by the nurse call slave unit is not acquired by the nurse call master unit except where the operated portable transmission device is present. Even if the portable transmission device where the call is performed exists, the information recorded by the nurse call slave unit is not acquired by the nurse call master unit unless the portable transmission device is operated. Therefore, patient privacy can be protected as much as possible. In addition, since it is only necessary to temporarily connect the line between the nurse call slave unit and the nurse call master unit installed in the place where the operated portable transmission device exists, the function of the nurse call device is improved. While alive, information can be obtained using the current nurse call device. Therefore, when a medical worker who has been violently abused or abused makes a report, it is possible to appropriately record the situation before the medical worker made the report. .

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of an emergency call system according to the present embodiment. As shown in FIG. 1, the emergency call system according to the present embodiment includes a nurse call slave device 1, a portable transmission device 10, a receiver 20, and a nurse call master device 30.

In the example shown in FIG. 2, only one nurse call cordless handset 1a, 1b, 1c is installed in each room A, B, C, but the number of beds in the room (in other words, the number of patients). Of course, the nurse call handset 1 may be provided in accordance with the above.

  The nurse call handset 1 includes an operation unit and a wall unit. The operation unit is placed on the bed or in the vicinity of the bed so that each patient in the hospital room can perform a call operation and a call at hand. The operation unit is connected to an outlet of the wall unit through a cord or the like. The operation unit also includes a call button (not shown) for a patient to call a medical worker. The wall unit is embedded in the bedside wall of each patient in the hospital room and is connected to a corridor lamp. In addition, the wall unit has a call button (not shown) for a medical worker to call another medical worker in an emergency, and the medical worker operates the original state when the patient calls the medical worker. And a recovery button (not shown) for returning to the power source, and an outlet (not shown) for connecting the operation unit. Further, at least one of the operation unit and the wall unit is provided with a microphone (not shown) and a speaker (not shown) that are used when the patient has a conversation with a medical staff.

  The nurse call slave unit 1 includes a slave unit control unit 2, a slave unit storage unit 3, a status recording unit 4, and a slave unit interface 5. The portable transmission device 10 is carried by a medical worker, and is hung on the neck of the medical worker by a string attached to the casing of the portable transmission device 10. The portable transmission device 10 includes a control unit 11, a call operation unit 12, a storage unit 13, and a wireless transmission unit 14.

  The receiver 20 is installed in each place (for example, each hospital room A, B, C, etc.) in the hospital. The receiver 20 is installed at least near the installation position of the nurse call slave unit 1. In general, the receivers 20 are distributed in the hospital so that a medical worker can receive a call signal (described later) transmitted from the portable transmission device 10 regardless of where in the hospital. ing. The receiver 20 is connected to a nurse call parent device 30 installed in a nurse center or the like by wire. The receiver 20 includes a receiver control unit 21, a reception unit 22, a measurement unit 23, a receiver storage unit 24, and a receiver interface 25.

  The nurse call parent device 30 is installed in a nurse center or the like where a medical worker is present, and is connected to the nurse call child device 1 by wire. In addition, the nurse call parent device 30 is provided with a handset (not shown) for notifying the call from the nurse call child device 1 and calling with the patient in response to the call. Here, the handset includes a microphone (not shown) and a speaker (not shown). Here, since a known technique is used for a method of calling or calling between the nurse call slave unit 1 and the nurse call parent unit 30, description thereof will be omitted. In addition, the nurse call parent machine 30 is provided with a confirmation operation unit (not shown) for notifying a call from the portable transmission device 10 and responding to the call. The nurse call parent device 30 includes a parent device control unit 31, a parent device interface 32, a parent device storage unit 33, an installation position information extraction unit 34, a nurse call child device identification unit 35, and a notification unit 36. Yes.

  First, each component of the nurse call handset 1 will be described. The subunit | mobile_unit control part 2 controls each component of the nurse call subunit | mobile_unit 1 so that it may mention later. The subunit | mobile_unit memory | storage part 3 has memorize | stored the subunit | mobile_unit identification information uniquely allocated to the nurse call subunit | mobile_unit 1. FIG. The situation recording unit 4 always records the situation around the nurse call slave unit 1, and in the present embodiment, a voice recording apparatus using a rewritable storage medium will be described as an example. Here, there is a limit to the time during which the situation recording unit 4 can record the sound, and after that time, the situation recording unit 4 overwrites the old recording contents and records the sound. Therefore, the status recording unit 4 is in a state where the latest status is always recorded. Further, the situation recording unit 4 records voice as voice data. The slave unit interface 5 is for connecting the nurse call slave unit 1 and the nurse call master unit 30, and is connected to the master unit interface 32 by wire.

  Next, each component of the portable transmission device 10 will be described. The control unit 11 controls each component of the portable transmission device 10 as described later. The call operation unit 12 is operated when a medical worker who has been violated or abused by a patient, a patient's family, or the like calls another medical worker. Here, the call operation unit 12 includes a push button or the like. In the case where it is considered that the patient or the patient's family may be furious when the medical worker presses the push button, the call operation unit 12 is configured so that the medical worker can make a call secretly. You may make it do.

  The storage unit 13 stores identification information uniquely assigned to the portable transmission device 10. In the portable transmission device 10 configured as described above, the control unit 11 detects the operation of the call operation unit 12. When the control unit 11 detects an operation of the call operation unit 12, the control unit 11 acquires identification information from the storage unit 13 and generates a call signal including the identification information. The wireless transmission unit 14 wirelessly transmits the call signal generated by the control unit 11. Here, since the calling signal transmitted from the wireless transmission unit 14 has characteristics that are not easily affected by the floor or ceiling interposed between the upper and lower floors, the receiver 20 existing on the upper and lower floors is connected to the portable transmission device. The paging signal transmitted from 10 is not received in error. Note that the paging signal characteristics are not limited to this as long as erroneous reception of the receiver 20 can be prevented by the characteristics of the receiver 20 and floor and ceiling characteristics.

  Next, each component of the receiver 20 will be described. The receiver control unit 21 controls each component of the receiver 20 as described later. The receiving unit 22 receives a call signal transmitted from the portable transmission device 10 via an antenna (not shown). The measurement unit 23 measures the reception level of the paging signal received by the reception unit 22 and outputs it to the receiver control unit 21 as reception level information. Usually, the closer the portable transmission device 10 is to the antenna of the receiver 20, the higher the reception level of the paging signal measured by the measurement unit 23.

  The receiver storage unit 24 stores receiver identification information uniquely assigned to the receiver 20. The receiver interface 25 is used to connect the receiver 20 and the nurse call parent device 30 and is connected to the parent device interface 22 by wire. When the receiving unit 22 receives the call signal, the receiver control unit 21 acquires the receiver identification information from the receiver storage unit 24 and inputs the reception level information output from the measurement unit 13. Then, the call signal received by the receiving unit 22, the receiver identification information, and the reception level information are associated with each other and output from the receiver interface 25.

  Next, each component of the nurse call parent machine 30 will be described. The base unit control unit 31 controls each component of the nurse call base unit 30 as described later. The master unit interface 32 is for connecting the nurse call master unit 30 and the receiver 20, and is connected to the receiver interface 25 by wire. Then, base unit control unit 31 inputs a call signal and receiver identification information and reception level information associated with the call signal from receiver 20 via base unit interface 32. Here, when a plurality of receivers 20 have received a call signal transmitted from the portable transmission device 10, the parent device control unit 31 inputs a plurality of call signals having the same identification information.

  The base unit storage unit 33 stores receiver identification information of all the receivers 20 installed in the hospital. Further, installation position information indicating the position where each receiver 20 is installed is stored in association with the receiver identification information. As a result, the nurse call parent device 30 can grasp the installation positions of all the receivers 20. Further, the parent device storage unit 33 stores the child device identification information of the nurse call child device installed near the position where the receiver 20 is installed and the receiver identification information of the receiver 20 in association with each other. . Here, the parent device storage unit 33 uses information such as a room number that can specify the position of the room as the installation position information. As described above, the base unit storage unit 33 stores the installation position information and the individual residence identification information in association with each other.

  Moreover, the main | base station memory | storage part 33 has the medical worker identification information (for example, a medical worker's name etc.) for identifying a medical worker, and the identification information of the portable transmission apparatus 10 which the medical worker carries. It is associated and remembered. Thereby, in the nurse call parent machine 30, the medical worker who performed the call can be specified.

  When the plurality of receivers 20 receive the call signal transmitted from the portable transmission device 10 having the same identification information, the installation position information extraction unit 34 analyzes each reception level information and determines the reception level. The largest receiver 20 is specified, and the installation position information stored in the parent device storage unit 33 in association with the identification information of the receiver is extracted.

  The nurse call child device identification unit 35 acquires the child device identification information stored in the parent device storage unit 33 in association with the installation position information extracted by the installation position information extraction unit 34, and performs the portable transmission in which the call is performed. The nurse call cordless handset 1 installed in the vicinity of a medical worker carrying the device 10 is specified. By such a series of operations of the nurse call master unit 30, which room the medical worker who has called is in (in other words, where the emergency occurred), and which room It becomes clear whether the nurse call cordless handset 1 is installed.

  The alerting | reporting part 36 alert | reports that there was a call from a medical worker. Here, the notification unit 36 includes a sound emitting device such as a speaker and a display device such as a liquid crystal display. Further, when notifying by the notification unit 36, the base unit control unit 31 identifies the medical worker who has made the call based on the identification information included in the call signal, and displays the name on the display device of the notification unit. I am doing so. Moreover, when the medical worker calls, the main | base station control part 31 displays the room number of a calling position. When such notification is performed, a medical worker (a medical worker other than the medical worker who made the call) in the vicinity of the nurse call parent device 30 operates a recovery operation unit (not shown) and performs notification by the notification unit 36. Stop the notification.

  On the other hand, the parent device control unit 31 connects a line to the nurse call child device 1 specified by the nurse call child device specifying unit 35, and the child device storage unit via the parent device interface 32 and the child device interface 5. 3 acquires the audio | voice data recorded by the subunit | mobile_unit identification information memorize | stored in 3 and the condition recording part. Here, the acquisition of the audio data by the base unit control unit 31 is continued until the predetermined timing comes after the recovery operation unit is operated. This is an operation for recording the situation in the field after the occurrence of an emergency, and a time of about several minutes is set. Then, when a predetermined timing elapses, base unit control unit 31 disconnects the line with nurse call handset 1.

  For example, in the case shown in FIG. 2, when a medical worker operates the call operation unit 12 of the portable transmission device 10, the receiver 20 b installed in the hospital room B receives the call signal. At this time, the receiver 20a in the room A and the receiver 20c in the room C do not receive the calling signal. In the receiver 20b, in addition to the call signal, the reception level information measured by the measurement unit 23 and the receiver identification information are associated with each other and transmitted from the receiver interface 25 to the nurse call parent device 30.

  In the nurse call parent machine 30, the medical worker who has called by the call signal received from the receiver 20b is specified, and the medical worker calls by the reception level information and the receiver identification information received from the receiver 20b. Specific room B is identified. Then, the nurse call child device specifying unit 35 specifies the nurse call child device 1b installed in the hospital room B. In the nurse call master unit 30, a line is connected to the nurse call slave unit 1b, and the voice data recorded in the status recording unit 4 of the nurse call slave unit 1b and the slave unit storage unit 3 are stored. Get handset identification information. At this time, the voice data recorded in the status recording unit 4 of the nurse call cordless handset 1b in the hospital room B is acquired by the nurse call master unit 30, but is recorded in the status recording unit 4 of the nurse call cordless handset 1b in the hospital room A. The voice data recorded and the voice data recorded in the status recording unit 4 of the nurse call cordless handset 1c in the hospital room C are not acquired by the nurse call master unit 30.

  Next, the operation of the emergency call system and the situation recording method according to the present embodiment will be described. FIG. 3 is a flowchart showing the operation of the emergency call system and the situation recording method according to the present embodiment. First, in the nurse call cordless handset 1, the situation recording unit 4 records the voice in the hospital room (step S1). Then, the handset controller 2 checks whether or not a line is connected from the nurse call base unit 30 (step S2).

  In the portable transmission device 10, the control unit 11 checks whether the call operation unit 12 has been operated (step S3). If control unit 11 determines that call operation unit 12 has not been operated (NO in step S3), the process in step S3 is repeated. On the other hand, when control unit 11 determines that call operation unit 12 has been operated (YES in step S3), control unit 11 generates and transmits a call signal (step S4).

  In the nurse call parent device 30, the parent device control unit 31 checks whether or not a call signal is input via the receiver 20 (step S5). If base unit control unit 31 determines that no paging signal is input (NO in step S5), the process in step S5 is repeated. On the other hand, if the parent device control unit 31 determines that the call signal has been input (YES in step S5), the medical worker who has called the parent device control unit 31 is identified, and the installation position information extraction unit The installation position of the receiver 20 is specified by 34, and the notification unit 36 performs notification (step S6).

  Then, the nurse call slave unit specifying unit 35 specifies the nurse call slave unit 1 installed in the vicinity of the installation position of the receiver 20, and the master unit control unit 31 communicates with the identified nurse call slave unit 1. To connect the line (step S7).

  In the nurse call handset 1, since the handset controller 2 checks whether or not the line is connected from the nurse call base unit 30 (step S2), it is determined that the line is not connected from the nurse call base unit 30. If it is determined by handset controller 2 (NO in step S2), the process in step S2 is repeated. On the other hand, if it is determined in the slave unit control unit 2 that the line is connected from the nurse call base unit 30 (YES in step S2), the voice data recorded in the status recording unit 4 is output. Then, the handset controller 2 checks whether or not the line is disconnected from the nurse call base unit 30 (step S9).

  In the nurse call parent machine 30, the parent machine control unit 31 acquires voice data (step S10). Then, the parent device control unit 31 checks whether or not a recovery operation has been performed (step S11). If base unit control unit 31 determines that a recovery operation has not been performed (NO in step S11), the process in step S11 is repeated. On the other hand, if base unit control unit 31 determines that a recovery operation has been performed (YES in step S11), notification by notification unit 36 is stopped and the line is disconnected at a predetermined timing (step S12). .

  In the nurse call handset 1, since the handset control unit 2 checks whether or not the line is disconnected from the nurse call base unit 30 (step S9), the line is not disconnected from the nurse call base unit 30. If it is determined by handset controller 2 (NO in step S9), the process in step S9 is repeated. On the other hand, when slave unit control unit 2 determines that the line is disconnected from nurse call base unit 30 (YES in step S9), slave unit control unit 2 stops outputting voice data (step S13). ).

  As described above in detail, according to the present embodiment, the call signal generated by the control unit 11 by operating the call operation unit 12 of the portable transmission device 10 carried by a medical worker is transmitted to the wireless transmission unit 14. , The receiving unit 22 of the receiver 20 installed in each hospital room with the installation position specified receives the calling signal, and the measuring unit 23 measures the reception level. In the nurse call parent device 30, the installation position information extraction unit 34 specifies the installation position of the receiver 20 having the highest reception level. On the other hand, in the nurse call handset 1, the surrounding sound is recorded by the situation recording unit 4. Then, the nurse call master unit 30 specifies the nurse call slave unit 1 installed in the vicinity of the installation position of the receiver 20 by the nurse call slave unit specifying unit 35, and the master unit control unit 31 specifies the specified nurse call unit. A line is connected to the call handset 1 so that the voice data recorded by the status recording unit 4 of the nurse call handset 1 is acquired.

  As a result, the voice data recorded by the status recording unit 4 of the nurse call slave device 1 is not acquired by the nurse call master device 30 except in the hospital room where the operated portable transmission device 10 exists. In the hospital room where the portable transmission device 10 is present, the nurse call parent device 30 acquires the voice data recorded by the status recording unit 4 of the nurse call slave device 1 unless the portable transmission device 10 is operated. It will never be done. Therefore, patient privacy can be protected as much as possible. In addition, voice data can be acquired simply by temporarily connecting a line between the nurse call slave unit 1 and the nurse call master unit 30 installed in a hospital room where the operated portable transmission device 10 exists. Therefore, voice data can be acquired using the current nurse call while utilizing the normal function of the nurse call (calling by the nurse call handset 1). Therefore, when a medical worker who has been violently abused or abused makes a report, it is possible to appropriately record the situation before the medical worker made the report. .

  In the above-described embodiment, even when the call operation unit 12 of the portable transmission device 10 is operated, the notification is performed only by the notification unit 36 of the nurse call parent device 30, but the present invention is not limited to this. For example, the portable transmission device 10 itself may perform the notification, or the nurse call handset 1 or the corridor lamp may perform the notification. Thereby, the medical worker near the field can respond quickly.

  Moreover, in this embodiment, although the nurse call subunit | mobile_unit 1 and the receiver 20 are provided separately, it is not limited to this. For example, the nurse call slave unit 1 and the receiver 20 may be provided integrally.

  In the embodiment described above, receiver identification information for identifying the receiver 20 is stored in the receiver storage unit 24 of the receiver 20 so as to identify the receiver 20, but the present invention is not limited to this. Not. For example, the nurse call parent device 30 may be configured to identify the connection terminal of the receiver 20 in the parent device interface 32 so that the receiver 20 can be identified for each connection terminal. This eliminates the need for each receiver 20 to have a receiver storage unit 24.

  In the above-described embodiment, the voice data is acquired only from the nurse call slave unit 1 installed in the vicinity of the receiver 20 having a high reception level as a call position candidate. However, the present invention is not limited to this. For example, the voice data may be acquired from some of the higher rank receivers 20 having a high reception level or from the nurse call slave unit 1 installed in the vicinity of all the receivers 20 that have received the call signal.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
