Description

  The present invention relates to a medical device monitoring system that monitors whether or not an abnormality has occurred in a medical device used for treatment of a patient in a medical field and notifies a medical provider when the abnormality is detected.

  As a conventional medical device monitoring device, for example, there is a medical device monitoring device described in JP-A-10-234680.

  In the field of terminal medicine where this medical device monitoring apparatus is used, pain relievers such as morphine may be used to treat patients.

  When given painkillers, patients may not be able to make their own nurse calls.

  However, the patient's hearing is functioning, and the conversation in the hospital room and the sound of the medical device may be heard.

  In particular, for patients who receive terminal care, in the absence of a health care provider, hearing a warning sound of a medical device over a long period of time gives great pain and anxiety to the patient with a short remaining period.

  In addition, when a state change occurs in a medical device used in a hospital room, etc., even if the medical device has a function to sound a warning sound, if the patient's hospital room is away from the nurse center, a private room, etc. When it is blocked from the outside corridor, etc., the warning sound of the medical device does not reach the nurse center and it is difficult for the health care provider (doctor or nurse) to recognize the change in the state of the medical device in a timely manner. There is a case.

  In addition, for medical devices that do not emit a warning sound when an abnormality occurs and notify the state change with a screen display such as an LED or video, the health care provider makes a timely change in the state of the medical device. It is even more difficult to recognize.

  In addition, when a warning sound is generated at night or the like, or when the warning sound is extended for a long period of time, there is a result of giving anxiety to a patient in a room next to the hospital room where the warning sound is generated.

  It is painful for a patient to continue to hear the warning sound of a medical device for a patient who has been subjected to the above-mentioned terminal medical treatment and cannot perform a nurse call by himself.

  In addition, all medical devices used in medical providers such as hospitals are not always accompanied by a function of notifying the nurse call system when an abnormality occurs in the medical device.

  In this case, a medical provider regularly checks the state of the medical device by visiting a patient's hospital room, and detects an abnormal state of the medical device.

  In view of the above-described background, there is an environment where processing is not performed in a timely manner even when a change in the state of the medical device occurs when the patient cannot perform the nurse call himself.

  In other words, there is a situation in the medical field where severe consequences may occur for patients who are unable to make their own nurse call if the regular check of the health care provider is delayed for some reason.

  In response to the above-mentioned medical situation, Japanese Patent Laid-Open No. 10-234680 as a conventional technique detects a warning sound by comparing a sound collected near a patient's bed with data recorded in advance. In this case, an invention for notifying the nurse center is described.

  FIG. 2 is an explanation of the internal functions of the medical supervision apparatus 1 of FIG.

  The medical supervision apparatus 1 includes a memory 202 for storing and developing a program for executing a monitoring process, a CPU 201 for executing the program, a system controller 203 for controlling the memory and peripheral circuits, and the medical supervision apparatus 1 of FIG. A sound detection control unit 207 that controls the microphone 102 (208 in FIG. 2), an image light detection control unit 209 that controls the camera 103 (210 in FIG. 2) attached to the optical sensor in FIG. A confirmation button 204 for notifying the medical monitoring device 1 of confirmation, a screen display unit 205 for displaying the state of the medical monitoring device 1, and the nurse call system slave device 107 for notifying the nurse call system. And a relay unit communication control unit 206.

  The system controller 203 has a built-in timer control unit 215, and the notification from the timer control unit 215 is transmitted via the notification signal 216 and the notification signal 217 to the sound detection control unit 207 and the image light detection control unit. 209 is connected with the HW signal, and is used for periodic monitoring of the medical device 105 in FIG. 1 and monitoring time and elapsed time control.

  In the memory 202, a program for overall control of the medical monitoring device 1 and a medical device 105 and a program for executing the monitoring control (hereinafter referred to as a monitoring control task) are developed and executed by the CPU 201.

  When the monitoring is executed, the sound detection control unit 207 digitizes the sound collected from the microphone 208 by the A / D conversion unit of the microphone input IF 221 and converts the data subjected to the filter processing by the filter processing unit 222 into sound data. The comparison unit 223 compares the data with the warning sound pattern data to determine whether the warning sound is generated.

  The determined result is stored in the data temporary storage unit 224 with reference to the time management unit 225, notified to the CPU 201 via the system controller 203, and the warning sound detection result is one of the means for detecting the abnormality to be monitored. Use as one.

  In the example of FIG. 2, the sound detection control unit 207 and the image light detection control unit 209 are functions that can perform warning sound detection and warning light detection with the HW function of each control unit (functions that can perform comparison processing and the like with an HW circuit). ).

  Similar to the sound detection control unit 207, the image light detection control unit 209 detects light of a preset wavelength with the optical sensor attached camera 210 when the monitoring is executed. In this case, the time management unit 235 is referred to, stored in the data temporary storage unit 234, notified to the CPU 201 via the system controller 203, and the warning sound determination result is used as one of the means for detecting the abnormality to be monitored. use.

  In addition, with regard to the image determination processing, data photographed by the optical sensor attached camera 210 is periodically digitized via the camera image input IF 231 based on notification from the CPU 201 or the timer control unit 215 of the system controller 203. The image data for abnormality determination that is temporarily stored and set in advance and the captured image data are compared with the image data at the time of occurrence of abnormality by the image data comparison processing unit 232, and the determination result is managed by time management. The data of the unit 235 is referred to, stored in the data temporary storage unit 234, notified to the CPU 201 via the system controller 203, and the warning sound determination result is used as one of the means for detecting the abnormality to be monitored.

  In FIG. 2, the data temporary storage unit 234 and the image data comparison processing unit 232 are illustrated as examples having functions that can be processed by a hardware circuit or the like as functions within the image light detection control unit 209. There is also means for recording the temporary storage unit 234 in the memory 202 and performing comparison processing by the CPU 201.

  The image light detection processing unit 209 also applies the light detection function to image detection.

  Specifically, when the medical device 105 to be monitored displays the state of the medical device 105, the state is displayed using an LED or a liquid crystal.

  Since light is used in all cases, the image area to be determined is extracted using the data from the light detection sensor as means for extracting the coordinates of the target image area when the image is taken with the camera 210 attached to the optical sensor. Used for.

  Next, the control flow of the medical supervision apparatus 1 of FIGS. 1 and 2 will be described with reference to FIGS. 3, 4 and 5.

  The example of FIGS. 3 to 5 has the configuration of FIGS. 1 and 2, and the medical device 105 to be monitored when two factors of detection of a warning sound and light detection by an optical sensor are detected at the same time. Is an example in which it is determined that an abnormality has occurred.

  3 to 5 are basic common flows of the monitoring control program (monitoring task) of the present invention.

  FIGS. 6 and 7 are explanations regarding the classification of timers used in monitoring task control and the specifications of data managed by the two detection processing units in FIG.

  In FIG. 3, first, in an initial setting such as monitoring target registration in step 301, the medical provider registers the medical device 105 as a monitoring target in the medical monitoring device 1 of FIG. 1.

  In the medical supervision apparatus 1, data of the medical device 105 to be used is registered in advance in a hospital or the like.

  For the registration, for example, a method in which a barcode is attached to the medical device 105, the barcode is read using the camera 210 attached to the optical sensor, and the medical device 105 is recognized and registered by the medical supervision apparatus 1, or the medical device 105 is registered. An RFID tag is attached to the medical supervisory device 1 and the medical supervisory device 1 has an RFID reading function so that the medical supervisory device 1 recognizes and registers the medical device 105.

  By registering the medical device 105 to be monitored in the medical supervision device 1, when the medical supervision device 1 recognizes the medical device 105 to be monitored, a monitoring menu is displayed on the screen, and effective according to the device is displayed. The monitoring mode (a combination of warning sound and light detection, or a combination of warning sound and light detection and image detection, or only light detection) is displayed on the screen of the medical monitoring device 1 so that the medical provider can select and set it. It becomes possible to do.

  When the medical supervision apparatus 1 recognizes and registers the monitoring target apparatus, the medical provider next sets three types of monitoring timers and a monitoring interval time n (for example, 10 seconds).

  Three types of monitoring timers will be described with reference to FIG.

  The monitoring timer A activates the monitoring timer A when the medical monitoring apparatus 1 detects an abnormality of the medical device 105 to be monitored and first notifies a nurse call, and sets the monitoring timer A (for example: If the confirmation button 204 for the notification of the nurse call is not input by the medical provider by the time 15 seconds elapses, it is used to notify the nurse call again when the monitoring timer A expires.

  In the monitoring timer B, after the medical monitoring apparatus 1 detects the abnormality of the medical device 105 to be monitored and notifies the nurse call first, the confirmation button 204 for the notification of the nurse call is input by the medical provider. The monitoring timer B is activated at the time point, and during the time set for the monitoring timer B (for example, 20 seconds), it is determined that the medical provider is performing a treatment for the abnormality of the medical device 105 to be monitored, This is used for the determination that the nurse call is not notified again even if an abnormality (when the volume of the warning sound is not amplified) is detected while the apparatus 1 is continuously monitoring.

  When the monitoring timer C notifies the expiration of the monitoring timer A and notifies the nurse call again, the monitoring timer C operates when the nurse call is notified again.

  If the confirmation button 204 is not input during the time set in the monitoring timer C (for example, 10 seconds) and the monitoring timer C expires, the medical monitoring device 1 determines that an emergency is required and notifies the nurse call. Notify the medical station 110 as well.

  The medical supervision apparatus 1 is connected to a nurse call system and has a function of notifying a nurse call center that manages a hospital room, but also a function of notifying a medical station 110 that has jurisdiction over the nurse call.

  The above is the contents regarding the initial setting of the medical supervision apparatus 1 performed in step 301.

  When the initial setting is completed, the medical monitoring device 1 starts monitoring the medical device by an input from the medical provider.

  When the medical supervision apparatus 1 starts monitoring, the process proceeds to step 302.

  The process of step 302 will be described with reference to FIGS.

  In step 302, at every time n intervals set in step 301, the time n has elapsed simultaneously from the timer control unit 215 to the sound detection control unit 207 and the image light detection control unit 209 using the notification signals 216 and 217. Is notified as the HW signal.

  The sound detection control unit 207 and the image light detection control unit 209 have internal counters in the reception units of the notification signal 216 and the notification signal 217, respectively, and set the time from the start of monitoring in the time setting by SW control from the CPU. As an HW-like process, the time is counted up, the elapsed time is managed by each time management unit, and the time is attached to the data collected inside each detection processing unit.

  Time setting by SW control is difficult if the sound detection control unit 207 and the LSI of the image light detection control unit 209 are not the same, but it is difficult to set the time at the same time. After the start is set by the SW control for the detection processing unit, the synchronization control can be performed by using the notification of the HW signal.

  Now, assuming that the monitoring start time is T, the sound detection control unit 207 and the image light detection control unit 209 generate a warning sound between time T and time (T + n) based on notifications from the notification signals 216 and 217. Whether or not warning light is detected.

  The two detection processing units independently perform detection determination.

  The sound detection control unit 207 digitizes the sound collected from the microphone, compares the data filtered by the filter processing unit 222 with the data for comparison and the sound data comparison unit 223, and the comparison result is the time management unit. Based on the time information of 225, the data is temporarily stored in the data temporary storage unit 224 in units of time n.

  Here, the data held in the temporary data storage unit 224 will be described with reference to FIG.

  Data stored in the data temporary storage unit 224 of the sound detection control unit 207 includes a warning sound detection determination result 601, a matched warning sound pattern 602, a collected volume 603, a collection time 604, and a value before time n. 5 types of elements such as an abnormal amplification detection flag 605 when a volume increase and a warning sound pattern difference are detected are managed in units of time n.

  Monitoring is started at time T, and the monitoring result from time T to time (T + n) is held in the data temporary storage unit 224 as the result of time n and set in advance at the time of the item (T + n). The sound detection control unit 207 writes to the memory 202 as a memory write master to the address of the memory 202 and notifies the CPU 201 of an interrupt.

  As another means, after notifying the CPU 201 of the interrupt, the CPU 201 may read the register of the sound detection control unit 207 and read the result of the data temporary storage unit 224.

  A feature of the sound detection control unit 207 of the present invention is that the five elements in FIG. 6 are managed in units of time n and used for subsequent monitoring determination processing.

  Next, the internal processing of the image light detection control unit 209 in step 302 will be described.

  In the example of FIG. 1, the image light detection control unit 209 of FIG. 2 performs a process of detecting an abnormality mainly by the light detection function.

  When the initial setting is executed in step 301, the light detected by the optical sensor attached camera 103 is notified to the image light detection control unit 209, and the light detection processing unit 233 inputs the light having the frequency set in step 301. It is determined whether it has been performed, and the result is recorded in the temporary data storage unit 234.

  Here, data managed by the data temporary storage unit 234 will be described with reference to FIG.

  The temporary data storage unit 234 compares the light detection determination result 611, the detected wavelength pattern 612, the light intensity 613, the sampling time 614, and the value before time n, and the light intensity is amplified. The five types of elements of the abnormal amplification detection flag 615 in the case of detecting is managed in units of time n and used for subsequent monitoring processing.

  The monitoring result from time T to time (T + n) is held in the data temporary storage unit 234 as the result of time n, and the image light detection control unit transfers to the address of the memory 202 set in advance at the time of item T + n. As a memory write master, 209 writes to the memory 202 and notifies the CPU 201 of an interrupt.

  As another means, there is a method in which the CPU 201 reads and processes a register of the image light detection control unit 209.

  The image light detection control unit 209 of the present invention is characterized in that the five elements in FIG. 6 are managed in units of time n and used for the subsequent monitoring process.

  Next, the processing after step 302 will be described.

  The processing after step 302 is a processing flow of a program (monitoring task) on the memory 202.

  In step 302, the monitoring results of the sound detection control unit 207 and the image light detection control unit 209 are confirmed at time (T + n), and both the warning sound detection result 601 and the light detection detection result 611 in FIG. In the case where both the warning sound detection result 601 and the light detection detection result 611 are not valid, the process proceeds to step 303 after determining that the abnormality is detected in the medical device 105 to be monitored. Performs the process of step 302 again at the next time T + 2n.

  In step 303, since the medical supervision apparatus 1 detects an abnormality in the medical device 105 to be monitored, the nurse call system slave unit 107 is disconnected via the relay device 104, and the nurse call system master unit 112 detects the abnormality. To be notified.

  Since the notification in step 303 is the first notification after the abnormality is detected, the monitoring timer A is started, and an abnormality that manages whether or not an abnormality is detected in the medical device to be monitored on the monitoring task program of the medical monitoring device 1 is detected. The detection flag is set to be valid, and the process proceeds to step 400.

  FIG. 4 and FIG. 5 are flowcharts for processing an event notified to the program monitoring task after time 400 (T + n) after the processing after step 400 after detecting an abnormality.

  The monitoring task is roughly notified of three events.

  The first event is a notification event from the confirmation button 204, the second event is an expiration notification event from the timers of the monitoring timer A, the monitoring timer B, and the monitoring timer C, and the third event is every time n units. These are periodic notification events from the two detection processing units in FIG.

  In the monitoring task, these three events are checked against the status of the monitoring target managed by the monitoring task, and processing corresponding to the notification is executed.

  In step 401, it is determined whether or not a confirmation input has been made by pressing the confirmation button 204 of the medical monitoring device 1 for the abnormality detection notification by the medical provider.

  If the confirmation button 204 is input, the confirmation input flag managed by the monitoring task program is set to be valid, and the process proceeds to step 402. If not input, the process proceeds to step 403.

  In step 402, since confirmation is input from the health care provider for the abnormality detection notification, the monitoring timer A is stopped, the monitoring timer B is started, and the process proceeds to step 400 to wait for the next event notification.

  In step 404, if the type of event notification from the timer is expiration notification from timer A or timer C, the process proceeds to step 510 to re-notify the nurse call system and notify the medical station 110. If they are different, the process proceeds to step 405.

  In Step 405, when the abnormality detection flag set in Step 303 is valid and the expiration of the monitoring timer B is notified, it is determined that the abnormality release processing of the medical device 105 by the medical provider is delayed, Proceeding to step 510, re-notification to the nurse call system and notification to the medical office 110 are executed.

  If the abnormality detection flag is not valid and the expiration of the monitoring timer B is not notified, the process proceeds to step 400 and waits for the next event.

  If there is no timer notification in step 403, the process proceeds to step 406, where it is determined whether it is a periodic detection event that is a periodic notification event from the sound detection control unit 207 and the image light detection control unit 209. , Go to step 500, if not, go to step 400 and wait for the next event.

  FIG. 5 shows a process when the periodic detection event is notified in FIG.

  When the routine proceeds to step 500, periodic abnormality detection determination is executed at step 501.

  When an abnormality is detected in both the sound detection control unit 207 and the image light detection control unit 209 at time T + n, when it is determined that an abnormality has occurred in the medical device 105, every time n after time T + n The abnormality detection determination is executed continuously.

  In step 501, in the abnormality detection determination at time T + 2n, if both warning sound detection and light detection detect abnormality as in time T + n, the process proceeds to step 502, and both warning sound detection and light detection are abnormal. If NO is detected, the process proceeds to step 503.

  In step 502, at time T + n and time T + 2n, the values of the abnormal amplification detection flag 605 for warning sound detection and the abnormal amplification detection flag 615 for light detection are checked to check whether abnormal amplification has been detected. As for this amplification confirmation method, whether the volume of warning sound detection and the light intensity of light detection are managed on the monitoring task program, and the difference between time T + n and time T + 2n is compared and amplified. It is also possible to judge whether.

  If abnormal amplification detection is confirmed at time T + n and time T + 2n, it is determined that the state of the medical device 105 is urgent, and the process proceeds to step 507 to notify the nurse call and the medical station 110 of the abnormal detection amplification for monitoring. Timer C is started.

  If the amplification of the abnormality is not detected, the abnormality is continuously detected, so the process proceeds to step 400 to wait for the timer notification or the confirmation button 204, and waits for the next event.

  When the process proceeds to step 503, the medical monitoring apparatus 1 detects an abnormality of the medical device 105 to be monitored, notifies the nurse call, and determines that the abnormality is canceled as a monitoring apparatus.

  As an example, the medical supervision apparatus 1 in FIG. 1 determines that the abnormality has been canceled when no abnormality is detected twice in succession after the confirmation to the nurse call is input by the health care provider.

  In step 503, it is determined whether the confirmation input flag is valid. If invalid, the process proceeds to step 400 to wait for the next event.

  This is because, once a nurse call is notified, confirmation by the health care provider is awaited for the notification.

  In step 503, if the confirmation flag is valid, the process proceeds to step 504, the invalid count is increased, and the process proceeds to step 505.

  In step 505, if the invalid count is not 2 or more as the continuous time, the process proceeds to step 400 and waits for the next event.

  When the invalid count is a continuous value of 2 or more, the process proceeds to step 506.

  For example, when the confirmation button 204 is input at time T + 3n, the confirmation input flag is set valid, and abnormality detection is detected invalid at time T + 4n and time T + 5n, in step 505, at time T + 5n. Initialize the status used in the monitoring task, set the abnormality detection flag to invalid, set the confirmation input flag to invalid, and process that the abnormality has been released.

  As described above, as the monitoring control of the medical device 105 of the present invention in FIG.

  Next, in addition to the warning sound and the warning light, the difference from the above description will be described regarding the flow in the case of using an image.

  In the initial setting of the image abnormality detection, the image of the medical device 105 is taken by the camera 103 with the optical sensor, the region for abnormality detection determination processing is extracted, and an abnormality detection pattern is set.

  As an abnormality detection pattern, there is a method of setting data on the display unit of the medical device 105 as an area to be determined, and when the medical device 105 is a syringe pump as in the example of FIG. It is also assumed that a method for determining an abnormality when the amount decreases can be selected.

  When selecting a plurality of locations, a plurality of optical sensor-attached cameras 103 are used, and the determination target process is individually monitored and determined.

  When the abnormality detection method is comparison of display data on the display unit of the medical device 105, it is possible to determine an image abnormality by comparing with the image data when the abnormality of the medical device 105 is set in advance. is there.

  When the abnormality detection method is the remaining amount of the syringe, a marker is attached to the warning position on the push-in portion side of the syringe and on the side where the syringe is provided, and each image as shown in FIG. It is registered in the initial setting so that it is determined that there is an abnormality when the markers are lined up, and the presence or absence of abnormality is determined based on whether or not the marker positions are extracted and lined up from the image data captured by the optical sensor attached camera 103.

  The other abnormality detection control is the same as the processing in FIGS. 3, 4 and 5 described above.

  Next, an example using FIG. 9, that is, an example in which there are two or more medical devices to be monitored will be described.

  The difference from FIG. 1 is that an optical sensor-attached camera 103 and an optical sensor-attached camera 113 are prepared for each medical device 111 and medical device 105 to be monitored for each medical device.

  3, 4, and 5, for example, in the monitoring of the medical device 105, the alarm sound and the warning light are both abnormal in the monitoring of the medical device 105, and the abnormality is detected in the medical device 105 and notified to the nurse call. After that, an abnormality of the medical device 111 may be detected.

  At this time, abnormal amplification detection is performed as the processing of Step 501 and Step 502 in FIG. 5, and a re-notification to the nurse call system and notification to the medical station 110 are performed as abnormalities with increased urgency.
