Description

  The present invention relates to a recording apparatus that is applied to a nurse call system in which a patient or a care recipient calls a medical worker such as a nurse in a facility such as a hospital and records information related to an incident or an accident.

Conventionally, nursing support systems collect incident (near-miss) information by text input by health care professionals as reports of events that do not lead to medical accidents but are dangerous to prevent medical accidents. Like to do.
It is important that this incident information is collected objectively and accurately over time so that the causal relationship in which the event occurred can be understood. However, for busy medical staff, there is a problem that character input of incident information is time-consuming and burdensome.

In addition, the technique which reads a part of incident information from an electronic medical record according to the generation | occurrence | production date and time, party information, patient information, and action information input by the medical worker is known (for example, refer patent document 1).
However, even in the technique described in Patent Document 1, the medical staff must input a character string indicating the occurrence date and time, the party information, the patient information, and the action information, and the amount of the character string to be input is still It remained a lot.

  The present invention has been made to solve the above-described problem, and an object thereof is to efficiently collect information related to, for example, incidents and accidents without putting a heavy burden on character input or the like on medical personnel. And

  In order to achieve the above object, the present invention establishes a communication link for performing voice communication between a calling terminal and a notification terminal when an instruction to respond to a call request is input. The conversation made through is converted into an audio signal and recorded on the recording means.

  According to the present invention, since conversations triggered by the occurrence of a call request are recorded, it is possible to efficiently collect information related to incidents and accidents without imposing a heavy burden on medical personnel. Can provide a nurse call system.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a nurse call system including a recording apparatus according to an embodiment of the present invention. This nurse call system includes hospital room units 11 to 1n (corresponding to calling terminals in claims) and a nurse call parent device 21 (corresponding to reporting terminals in claims).

The hospital room units 11 to 1n include a microphone 101, a speaker 102, an I / O (Input / Output) unit 103, a nurse call outlet 104, a call button 105, a hospital room camera 106, and an individual information corridor lamp 107. Prepare.
The microphone 101 and the speaker 102 are respectively installed on the ceiling of a hospital room and are used for a telephone call between a patient and a medical worker who has responded to a call from the patient. The microphone 101 converts a voice uttered by a patient into an audio signal. The speaker 102 outputs the voice of the medical staff. The I / O unit 103 accommodates the microphone 101 and the speaker 102 and connects them to the individual information corridor lamp 107.

  The nurse call outlet 104 accommodates a call button 105 and connects it to the individual information corridor lamp 107. The call button 105 receives a call request from a patient, and a button operation is performed when a call is made. The call button 105 includes a “general” key for making a normal call and an “emergency” key for making an emergency call.

  This button operation is notified to the individual information corridor lamp 107 through the nurse call outlet 104 by an electric signal. In response to a button operation, a different electrical signal is notified to the individual information corridor lamp 107, so that the individual information corridor lamp 107 can identify which one of the “general” key and the “emergency” key is operated.

The hospital room camera 106 captures an image of the patient room and captures a patient who has called the patient, a cared person, and the like. The captured video is converted into a video signal and output to the individual information corridor lamp 107.
The individual information corridor lamp 107 has a function of communicating with the nurse call master device 21. The individual information corridor lamp 107 receives the voice signal of the medical worker from the nurse call master unit 21 and outputs it to the I / O unit 103. When the individual information corridor lamp 107 receives an electrical signal indicating a call from the call button 105 through the nurse call outlet 104, the call type information indicating whether the call is “general” or “emergency” according to the electrical signal. And the address information of the call button 105 are transmitted to the nurse call master unit 21 as a call signal. The individual information corridor lamp 107 transmits an audio signal input from the I / O unit 103 and a video signal input from the hospital room camera 106 to the nurse call parent device 21.

  Next, the configuration of the recording apparatus according to the present embodiment, for example, the nurse call parent device 21 will be described. As shown in FIG. 2, the nurse call master unit 21 includes a control unit 210, a storage unit 211 (corresponding to the recording means in the claims), a hospital room unit I / F (Interface) unit 212 (corresponding to the image data input unit). ), A display 213, an input unit 214 (corresponding to input means in claims), a call unit 215, a notification unit 216, and a clock unit 217.

  In addition, the control unit 210 includes a recording control unit 210a (corresponding to the recording control unit in the claims), a communication establishment unit 210b (corresponding to the communication establishment unit in the claims), and a conversion unit 210c (invention). A range conversion unit), a keyword determination unit 210d (corresponding to a claim keyword determination unit), a conversation time determination unit 210e (corresponding to a claim conversation time determination unit), a response time determination unit 210f ( Equivalent to the response time determination means in the claims), and a call type determination unit 210g.

  In addition to storing the control program and control data of the control unit 210, the storage unit 211 associates the address information of the call button 105 with the name of the patient and the place name (patient number, bed number, etc.) using the call button 105. The slave unit information table is stored. Further, the storage unit 211 stores a responder information table in which a key for each responder provided in the input unit 214 described later is associated with a responder name.

  The hospital room unit I / F unit 212 is an interface that communicates with the individual information corridor lamps 107 of the hospital room units 11 to 1n. The display 213 displays various information, and displays information indicating the occurrence of a call, for example. The input unit 214 is an input interface that receives a request from a medical worker, and performs an operation of responding to a call when, for example, a call occurs. It should be noted that a key is provided for each responder in the input unit 214 so that it can be seen who responded when performing the response operation.

  The call unit 215 includes a microphone and a speaker, and is used for a call between a medical worker who has responded to a call and a patient who has made the call. The notification unit 216 outputs a melody sound indicating the occurrence of a call out loud. The clock unit 217 measures time.

The control unit 210 controls the respective units of the nurse call parent device 21 according to the control program and control data stored in the storage unit 211.
Specifically, when the room unit I / F unit 212 receives the call signal, the control unit 210 generates a call ID (Identity) unique to the call signal received by the room unit I / F unit 212, and the clock unit The time measured by 217 is detected as the call occurrence time, and the address information included in the call signal is detected. And the control part 210 extracts the patient name and the place name corresponding to the said address information with reference to the subunit | mobile_unit information table memorize | stored in the memory | storage part 211, This is displayed on the display 213, Moreover, alerting | reporting part 216 is driven to generate a ringing tone, and the occurrence of the calling is notified.

  In addition, when the health care worker is instructed to respond to the call by operating the input unit 214 while the notification unit 216 is generating a ringing tone, the control unit 210 is stored in the storage unit 211. The responder corresponding to the operated key of the input unit 214 is extracted with reference to the responder information table. In addition, the control unit 210 detects the time measured by the clock unit 217 as a response time, and the communication establishment unit 210b of the control unit 210 controls the hospital room unit I / F unit 212 to determine whether the call has occurred. Establish a voice communication link between

  Then, the control unit 210 outputs the audio signal received by the room unit I / F unit 212 from the room unit from the call unit 215 and displays the video based on the video signal received by the room unit I / F unit 212. To display. In addition, the control unit 210 converts the voice of the medical worker input from the call unit 215 into an audio signal and transmits the audio signal to the hospital room unit where the call has occurred through the hospital room unit I / F unit 212.

Furthermore, the recording control unit 210a of the control unit 210 records the audio signal, the video signal, the detected patient name, the call generation time, the response time, the call end time, and the responder name in the storage unit 211 in association with each call ID. To do.
The conversion unit 210c of the control unit 210 converts the voice signal into text data using a known voice recognition technique or the like. This text data is recorded in the storage unit 211 by the recording control unit 210a.

Here, the data recorded in the storage unit 211 may be any of the above-described audio signal, video signal, text data, detected patient name, call occurrence time, response time, call end time, responder name. Good or all.
The keyword determination unit 210d of the control unit 210 determines whether a preset keyword is included in the text data. When the keyword determination unit 210d determines that a preset keyword is included in the text data, the recording control unit 210a records the converted text data in the storage unit 211. Here, the keyword set in advance is a word that the health care professional should not say to the patient.

  The conversation time determination unit 210e of the control unit 210 detects the conversation time between the medical worker and the patient based on the response time measured by the clock unit 217 and the call end time, and the conversation time is determined. Is longer than a predetermined time (for example, 5 seconds). In such a case, when the conversation time determination unit 210e determines that the conversation time is shorter than the predetermined time, the recording control unit 210a erases the information recorded in the storage unit 211. Here, the case where the conversation time is shorter than the predetermined time refers to a case where a medical worker responds to the patient such as “I will go immediately” and immediately rushes to the patient's room. .

  Further, the response time determination unit 210f of the control unit 210 detects the time from when the call is generated by the patient until the medical worker responds based on the call occurrence time and the response time measured by the clock unit 217. Then, it is determined whether or not the response time is equal to or longer than a preset time (for example, 30 seconds). In such a case, if the response time determination unit 210f determines that the time until response is longer than a preset time, the recording control unit 210a records the information in the storage unit 211. Here, the case where the time until the response is longer than the preset time indicates a case where the medical staff has not responded easily to the patient's call.

  Further, the call type determination unit 210g of the control unit 210 determines whether the call type by the patient is “general” call or “emergency” based on the call type information included in the call signal received by the hospital room unit I / F unit 212. Determine if it is a call. In such a case, when the call type determination unit 210g determines that the call type is “general”, the recording control unit 210a deletes the information recorded in the storage unit 211.

  Note that the condition of the audio signal, the video signal, and the text data stored in the storage unit 211 may satisfy any of the above-described conditions, or may satisfy all of them. Further, when there is a sufficient capacity in the storage unit 211, all data may be stored.

  Next, the operation of the nurse call system configured as described above will be described. Here, an operation related to the present invention, that is, an operation for recording / saving various information related to the request when a call request is given will be described. Hereinafter, this operation will be described with reference to FIG.

FIG. 3 is a flowchart showing processing performed by the control unit 210. The control unit 210 performs the above processing according to the control program and control data stored in the storage unit 211, and each time a call request is generated. This process is repeatedly executed.
First, when the call button 105 is operated and an operation signal is input to the individual information corridor lamp 107 along with this, the individual information corridor lamp 107 displays the occurrence of the call on its own display unit and the individual information. Address information corresponding to the corridor lamp 107 is detected, and a call signal including the address information is transmitted to the nurse call master unit 21.

  The individual information corridor lamp 107 activates the hospital room camera 111 when the call signal is transmitted. As a result, the hospital room camera 111 starts photographing and outputs a video signal obtained by photographing to the individual information corridor lamp 107. Thereby, the state of the calling room or the state of the patient is photographed. This video signal is output to the nurse call master unit 21 through the individual information corridor lamp 107.

In the nurse call master device 21, the hospital room unit I / F unit 212 receives the call signal and notifies the control unit 210 of the call signal. Then, the control unit 210 recognizes that a call has occurred and starts the processing shown in FIG.
First, the control unit 210 generates a call ID that is uniquely assigned to the current call (step 3a). The control unit 210 detects the current call occurrence time (hereinafter referred to as the call occurrence time) from the current time measured by the clock unit 217 (step 3b).

  The controller 210 extracts address information from the calling signal received by the hospital room unit I / F unit 212. Then, the control unit 210 refers to the child device information table stored in the storage unit 211, extracts the patient name and location name corresponding to the extracted address information, and identifies the patient who has called (step 3c). ).

The control unit 210 displays the information (patient name and place name) extracted from the storage unit 211 in step 3c on the display 213 and controls the notification unit 216 to generate a melody sound to notify the occurrence of a call. (Step 3d).
The control unit 210 monitors an operation on the input unit 214 and monitors whether or not a medical worker responds to the call (step 3e). Here, when a medical worker responds to the call, he / she operates a key corresponding to the user provided in the input unit 214 of the nurse call parent device 21 to respond to the call. When the control unit 210 determines that the input unit 214 has been operated (Yes in step 3e), the control unit 210 refers to the responder information table stored in the storage unit 211 and has performed the input The respondent corresponding to the key of the unit 214 is extracted and the medical worker who has made a response is specified (step 3f).

The control unit 210 detects the current time measured by the clock unit 217 as a response time (step 3g). The response time determination unit 210e of the control unit 210 obtains the response time required from the call generation to the response based on the response time detected in step 3g and the call generation time detected in step 3b (step 3h). .
The communication establishment unit 210b of the control unit 210 controls the hospital room unit I / F unit 212 to establish a voice communication link with the hospital room unit where the call has occurred (step 3i). As a result, voice communication is possible between the nurse call master unit 21 and the equipment of the hospital room unit where the call has occurred.

  The recording control unit 210a of the control unit 210 converts the audio signal of the conversation made through the audio communication link established in step 3i into audio data of a predetermined audio compression format, and records this in the storage unit 211. Record with. In addition, the recording control unit 210 a converts the video signal received by the hospital room unit I / F unit 212 from the hospital room unit where the call has occurred into video data of a predetermined moving image compression format, and records this in the storage unit 211. Recording is performed (step 3j).

  The audio compression format is, for example, WMA, mp3, AAC, OggVorbis, etc. That is, the audio signal exchanged through the audio communication link is compressed by the recording control unit 210a and recorded in the storage unit 211 as an audio file. The predetermined moving image compression format is, for example, WMI, AVI, MPEG, DivX, or the like. That is, the video signal is compressed by the recording control unit 210a and recorded in the storage unit 211 as a moving image file.

  The control unit 210 monitors whether or not a medical worker has performed an end-of-call operation using the input unit 214 (step 3k). When the control unit 210 determines that the call termination operation has not been performed by the input unit 214 (No in step 3k), the processing in step 3k is repeated. On the other hand, when the control unit 210 determines that the call-termination operation has been performed by the input unit 214 (Yes in step 3k), the communication establishment unit 210b controls the hospital room unit I / F unit 212 to perform step While releasing the voice communication link established in 3i, the recording control unit 210a ends the recording and recording started in step 3j (step 3l).

The conversation time determination unit 210e of the control unit 210 detects the time when the call is ended from the current time measured by the clock unit 217 as the call end time, and the response time detected at step 3g. Based on the above, the call time is obtained (step 3m).
Then, storage processing (step 3n) is performed as follows. The conversion unit 210c of the control unit 210 converts the recorded voice into text data using a known voice recognition technique based on the voice data recorded in the storage unit 211 by the recording control unit 210a. Further, the keyword determination unit 210d of the control unit 210 determines whether or not a preset keyword is included in the text data converted by the conversion unit 210c. The response time determination unit 210f determines whether or not the response time obtained in step 3h is longer than a preset time. Further, the conversation time determination unit 210e determines whether or not the call time obtained in step 3m is shorter than a preset time.

  The recording control unit 210a records the above-described text data only when the keyword determination unit 210d determines that a preset keyword is included in the text data after recording a later-described nurse call history in the storage unit 211. The information is stored in the storage unit 211 in association with the history.

  Further, the recording control unit 210a adds the recorded audio data and the recorded video data to the nurse call history only when the response time determination unit 210f determines that the response time obtained in step 3g is longer than the preset time. The data are stored in the storage unit 211 in association with each other. On the other hand, if the response time obtained in step 3g is shorter than the preset time, the recording control unit 210a deletes the audio data and video data from the storage unit 211.

The recording control unit 210a does not store the recorded audio data and the recorded video data when the conversation time determination unit 210e determines that the call time obtained in step 3m is shorter than the preset time. From the storage unit 211.
Further, the recording control unit 210a determines whether the call type by the patient is “general” call or “emergency” call based on the call type information included in the call signal. If it is determined that the call type is “general” call, the recorded audio data and recorded video data are deleted from the storage unit 211 without being saved. Thus, when the storage process is performed, the control unit 210 ends a series of processes.

  Here, the information stored as the nurse call history includes the call occurrence time detected in step 3b, the patient name and place name extracted in step 3c, the responder name detected in step 3f, the response time obtained in step 3h, and the like. is there. These pieces of information are associated with the call ID generated in step 3a and recorded in the storage unit 211 by the recording control unit 210a.

  On the other hand, when the control unit 210 determines that the medical staff does not respond to the call notified in step 3d (No in step 3e), the control unit 210 measures the timepiece unit 217. The current time is detected (step 3o). Then, the control unit 210 compares the call occurrence time detected in step 3b with the current time measured by the clock unit 217, and determines whether or not a predetermined time has elapsed (step 3p). Here, the predetermined time is a time that is determined by the control unit 210 that the medical staff has not responded to the patient's call, and is therefore set longer (for example, 30 minutes). When the control unit 210 determines that the predetermined time has not elapsed (No in step 3p), the process proceeds to step 3e.

  On the other hand, when the control unit 210 determines that the preset time has elapsed (Yes in step 3p), the control unit 210 detects the current time from the clock unit 217 (step 3q). The recording control unit 210a records the nurse call history in the storage unit 211 in association with the call ID generated in step 3a (step 3r). Here, the information stored as the nurse call history includes the call occurrence time detected in step 3b, the patient name and place name detected in step 3c, the current time detected in step 3n, and the information that the call was not answered. Etc. Thus, when the storage process is performed, the control unit 210 ends a series of processes.

  Thereafter, the call ID is designated through the input unit 214 of the nurse call master device 21, so that it corresponds to the call ID designated from the information accumulated in the storage unit 211 by the storage processing in step 3n and step 3r. Information is read from the storage unit 211 by the control unit 210. The control unit 210 displays the read information on the display 213, and outputs the read information (recorded voice or the like) from the call unit 215.

  As described above, in the recording apparatus configured as described above, when a call is generated from a patient or the like, a conversation made for each call is automatically recorded. For this reason, it is possible to efficiently collect information related to incidents and accidents by voice without placing a heavy burden such as character input on the medical staff. In addition, the medical staff can create an incident report or an accident report by playing back the recorded voice and listening to the voice at a convenient time.

  Therefore, when an incident or an accident occurs, the incident report or the accident report can be surely performed at a convenient time without taking a memo or inputting characters. As a result, it is possible to efficiently collect information related to incidents and accidents without imposing a heavy burden on medical staff.

  Corresponding to the recorded voice file, the call occurrence time, the caller (calling location), the response time and the response time required for the response, the call time, the text data in which the recorded conversation is converted into text, the caller Since the video signal etc. which image | photographed is recorded on the memory | storage part 211, the detailed information regarding a call can be preserve | saved.

  Accordingly, the supervisor of the health care worker can extract a specific call based on information related to the call. For example, it is possible to identify a case where the response time is abnormally long or a case where an inappropriate word is included in a word issued by a medical worker, and a call corresponding to this can be extracted.

  Also, the data to be saved is selected based on various conditions such as the type of call (for example, general call, toilet assistance call, drip end call, etc.), call time, response time, keywords included in text data, etc. Therefore, the storage capacity of the storage unit 211 can be saved.

  Also, by linking various information saved due to the call to treatment records and orders, business analysis can be performed efficiently, and it can also be used to predict the call for each patient. . In addition, the stored information can be easily presented even when provision of information is requested from a patient's family or the like.

  In the above embodiment, various information resulting from the call is recorded in the storage unit 211 that stores the control program and control data of the control unit 210. However, the information is stored in a separately provided hard disk or removable media. Various information resulting from the call may be recorded.

  In addition, data can be selected according to the patient's rescue category (transport, escort, walking alone). For example, it may be possible to save data only in the case of transportation. Specifically, the storage unit 211 stores the address information of the call button 105 and the name of the patient who uses the call button 105 in association with the information on the rescue category corresponding to the patient as a slave unit information table. In step 3n, the control unit 210 refers to the slave unit information table to determine the rescue category of the patient who has called the patient. If the rescue category is other than “transport”, the recorded audio data and recorded video data are deleted from the storage unit 211 without being saved.

  Moreover, in the said embodiment, although the keyword contained in the text data which converted conversation is used as conditions for selection of the information to preserve | save, it is not limited to this. For example, according to keywords (for example, patient requests) included in text data converted from conversations, call types are classified into genres, and priorities (urgent levels) are ranked. Also good. Thereby, since text data is sorted according to the conditions mentioned above, it becomes easy for a medical worker to confirm text data.

  Moreover, in the said embodiment, although the case where the medical worker responded with the nurse call main | base station 21 with respect to the call was mentioned as an example, it demonstrated and it was not limited to this. For example, you may make it respond with wireless units, such as a PHS (Personal Handyphone System) cordless handset which a medical worker carries. Even in this case, it is possible to record the voice of the conversation made.

  Specifically, the configuration is as shown in FIG. In other words, the handheld squall main device 3 and the wireless base stations 61 and 62 of the wireless unit 6 are provided. The handheld squall main device 3 is, for example, a switching device compatible with the local PHS, and to which the radio base stations 61 and 62 of the radio unit 6 are connected.

Each of the radio base stations 61 and 62 forms a radio area, and is connected to the mobile terminals 71 to 7m existing in the radio area via a radio line. The portable terminals 71 to 7m are carried by medical workers such as doctors and nurses and caregivers.
In such a configuration, when a call is generated, the nurse call master device 21 notifies the mobile terminals 71 to 7m of the call through the handin call main device 3 and the radio base stations 61 and 62. When any portable terminal responds to this notification, the identification information of the responding portable terminal is notified to the nurse call parent device 21 through the radio base stations 61 and 62 and the hand-in-hand call main device 3.

  The storage unit 211 of the nurse call parent device 21 stores the identification information of the portable terminals 71 to 7m and the name of the person who uses the information in association as a responder information table in advance. In step 3f shown in FIG. 3, the control unit 210 of the nurse call parent device 21 refers to the notified identification information and the responder information table, and identifies the medical worker who made the response.

  In step 3i, the communication establishment unit 210b of the control unit 210 establishes a voice communication link between the mobile terminal that has responded and the hospital room unit from which the call has occurred. According to such processing, even when a medical worker responds with a wireless unit such as a PHS cordless handset, it is possible to record the voice of the conversation made.

  In addition, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. Further, for example, a configuration in which some components are deleted from all the components shown in the embodiment is also conceivable. Furthermore, you may combine suitably the component described in different embodiment.
