Description

  The present invention relates to an IABP driving device used for driving a driven device in IABP (aortic balloon pumping).

  On the other hand, there is a case where it is desired to check whether or not past driving has been normally performed in the inspection of the IABP driving device or the like, and a technique for storing driving state data in a memory card or the like has been proposed (Patent Document 1). reference).

JP-A-9-2225022

  However, the conventional IABP driving device can display waveforms of past driving conditions and the like unless the data recorded on the memory card or the like is read by an analysis computer prepared separately from the IABP driving device. There wasn't. Therefore, it is difficult for the conventional IABP driving device to quickly check and analyze the past driving situation at the installation site of the IABP driving device when a problem or the like is suspected.

  The present invention has been made in view of such a situation, and relates to an IABP driving apparatus that can check and analyze past driving conditions and can easily perform inspections.

In order to achieve the above object, an IABP driving apparatus according to the present invention includes:
An IABP driving device for attaching a balloon catheter to which a balloon is connected, inflating and deflating the balloon,
A driving status monitoring unit that monitors the driving status of the IABP driving device and detects whether or not a predetermined event has occurred;
A storage unit for storing information about the event;
A display unit for displaying information on the IABP driving device;
A display control unit that controls display content of the display unit, and the driving status monitoring unit associates with the event history that is the history of the event, waveform data indicating the driving status before and after the event occurrence , Stored in the storage unit,
The display control unit causes the display unit to display the contents of the waveform data stored in the storage unit in association with the event history.

  Since the IABP driving device according to the present invention has a display control unit that displays the waveform data stored in the storage unit on the display unit in association with the event history, even if a computer for analysis is not separately prepared, It is possible to check and analyze past driving conditions with the IABP driving device alone. Therefore, the user or maintenance staff can easily check the IABP drive device as necessary. Furthermore, the user at the site of the IABP drive device shares the technical information regarding the IABP drive device at the medical site by displaying the past drive status of the IABP drive device on the display unit of the IABP drive device, It is possible to deepen understanding about the optimal usage of the IABP drive.

  For example, the drive status monitoring unit may store the waveform data from 1 to 60 seconds before the occurrence of the event to 1 to 60 seconds after the occurrence of the event in the storage unit.

  By appropriately setting the storage time of the waveform data, it is possible to appropriately check the driving state at the time of event occurrence while suppressing the storage capacity required for the storage unit.

  Further, for example, the waveform data may include blood pressure data related to a patient's blood pressure, electrocardiographic data related to an electrocardiogram from an electrocardiograph attached to the patient, and balloon internal pressure data related to the internal pressure of the balloon. good.

  Since the blood pressure data, the electrocardiogram data, and the balloon internal pressure data are very useful data for recognizing the driving situation at the time of event occurrence, such an IABP driving device appropriately checks the driving situation at the time of event occurrence. Is possible.

Further, for example, the storage unit may store explanation display information that is information to notify a user about the event,
The display control unit may cause the display unit to display the contents of the explanation display information in association with the event history.

  By displaying the contents of the explanation display information on the display unit, it is possible that even a user of an IABP drive device at a medical site who is not a maintenance company of an IABP drive device can take an appropriate countermeasure against the occurrence of an event. Become.

  For example, at least a part of the event may be accompanied by an alarm operation by a pilot lamp included in the IABP driving device.

  The fact that the warning operation is performed normally is a very important matter in the inspection of the IABP drive device, etc. Therefore, the IABP drive device that can check the drive status at the time of the past warning operation performs a more accurate inspection. Is possible.

  In addition, for example, when the display control unit displays the contents of the waveform data on the display unit, a caution display indicating that the waveform data is before and after the occurrence of the past event is displayed on the display unit. It may be displayed.

  By performing the caution display, it becomes clear that the waveform data displayed on the display section does not indicate the current driving status, but indicates the past driving status. Use can be prevented.

The meaning of the display is different.

  The shock absorbing unit 57 protects the display unit 54 and the pilot lamp 55 from shocks that occur when the camera is dropped. The material of the shock absorbing part 57 is not particularly limited, but is made of an elastic material such as rubber or elastomer.

  FIG. 3 is a block diagram showing the internal configuration of the monitor unit 50. The monitor unit 50 includes a control unit 52, a storage unit 60, an external memory mounting unit 58, and the like in addition to the display unit 54, the pilot lamp 55, and the input unit 56 shown in FIGS. The control unit 52 and the storage unit 60 are housed inside the housing of the monitor unit 50.

  The control unit 52 controls the IABP driving device 10. The control unit 52 includes a drive control unit 52a that controls the driving of the balloon catheter 80 that is a driven device, a drive status monitoring unit 52b that monitors the drive status of the IABP driving device 10 as a whole by the drive control unit 52a, and a display unit. And a display control unit 52c for controlling the display content of the display 54. The drive control unit 52a, the drive status monitoring unit 52b, and the display control unit 52c are functional components depending on the calculation contents, and the control unit 52 may be configured by one microprocessor. The components may be constituted by different integrated circuits.

  The drive control unit 52a receives signals from an electrocardiograph attached to the patient, the balloon catheter 80, various sensors incorporated in the apparatus main body 20, and the like, and performs arithmetic processing to control the pressure generating means 26 of the apparatus main body 20. Then, the balloon catheter 80 is driven. The drive control unit 52a can read out control information 68 necessary for driving the pressure generating unit 26 and the like from the storage unit 60.

  The driving status monitoring unit 52b monitors the driving status of the entire IABP driving device 10 including the balloon catheter 80, and detects whether or not a predetermined event has occurred during driving of the IABP driving device 10. Further, when the IABP driving device 10 detects that a predetermined event has occurred, the IABP driving apparatus 10 stores the predetermined information in the event storage unit 62 or changes the lighting state of the pilot lamp 55, etc. Implement the corresponding control.

  The event detected by the driving condition monitoring unit 52b is not particularly limited, but at least a part of the event includes an event accompanied by an alarm operation by the pilot lamp 55. The driving condition monitoring unit 52b is related to, for example, a serious problem (for example, abnormal operation of the driving control unit 52a or abnormal pressure for inflating / deflating the balloon 82), driving stoppage of the IABP driving device 10 or patient life. When a warning is detected, the pilot lamp 55 is lit in red. When a minor problem (for example, an event that may cause a serious problem if left unattended) is detected, the pilot lamp 55 is lit in yellow. The alarm action is performed. The driving status monitoring unit 52b lights the pilot lamp 55 in green when the balloon 82 is driven normally.

  Examples of the events detected by the drive status monitoring unit 52b include, for example, “helium gas mole”, “battery remaining amount low”, “balloon internal pressure drop”, “trigger detection failure”, “balloon internal pressure is high”, and “line hysteresis”. , “Balloon connection failure”, and the like are related to changes in driving conditions and signs of changing driving conditions.

  When detecting an event, the drive status monitoring unit 52 b stores information on the detected event in the event storage unit 62 in the storage unit 60. The event storage unit 62 has event history data 63 that stores an event history such as the type of event that occurred during driving and the time at which the event occurred. Each time the driving condition monitoring unit 52b detects an event, the driving condition monitoring unit 52b adds information on the new event to the event history data 63 and updates the event history data 63.

  In addition, the event storage unit 62 includes a waveform storage unit 64 that stores waveform data indicating the driving state of the IABP driving device before and after the occurrence of the event. When detecting a predetermined event, the drive status monitoring unit 52 b stores the waveform data in the waveform storage unit 64 in association with the event history stored as the event history data 63. The length of the waveform data stored in the waveform storage unit 64 is not particularly limited, but it is preferable to store the waveform data from 1 to 60 seconds before the occurrence of the event to 1 to 60 seconds after the occurrence of the event. .

  The waveform data stored in the waveform storage unit 64 is a characteristic value group continuously acquired at a predetermined sampling interval, and relates to blood pressure data 64a relating to the blood pressure of the patient and electrocardiographs from an electrocardiograph attached to the patient. The electrocardiographic data 64b and balloon internal pressure data 64c relating to the internal pressure of the balloon 82 are exemplified. Even when no event occurs, the waveform data is stored in the temporary storage unit 61 of the storage unit 60 for a predetermined time under the control of the drive control unit 52a. However, the waveform data stored in the temporary storage unit 61 is sequentially updated while driving is continued, and old waveform data is automatically deleted by storing new waveform data. When the drive status monitoring unit 52b detects a predetermined event, the drive status monitoring unit 52b reads the waveform data stored in the temporary storage unit 61, so that not only the waveform data after the occurrence of the event but also the waveform data before the occurrence of the event is stored in the waveform. It can be stored in the unit 64. The waveform data stored in the waveform storage unit 64 is not erased unless a predetermined erase instruction is input via the input unit 56 or the like. The storage time of the waveform data in the temporary storage unit 61 is not particularly limited, but it is preferable that the waveform data can be stored for a time longer than the length of the waveform data before the event occurrence stored in the waveform storage unit 64, for example, about 80 seconds. can do.

  FIG. 4 is a conceptual diagram illustrating a data storage state in the event storage unit 62. When adding information related to a new event to the event history data 63, the driving condition monitoring unit 52b assigns identification codes (“001”, “002”, “003” in FIG. 4) corresponding to the new event. The type of event and the time of occurrence are stored. In addition, the driving condition monitoring unit 52b assigns an identification code corresponding to a new event to the blood pressure data 64a, the electrocardiographic data 64b, and the balloon internal pressure data 64c stored in the waveform storage unit 64 as well as the event history data 63. Then, each waveform data (blood pressure data 64a, electrocardiogram data 64b, balloon internal pressure data 64c) is stored in the waveform storage unit 64.

  In this way, by assigning an identification code indicating that the information is related to a specific event, the specific event stored as the event history data 63 and the waveform data before and after the occurrence of the specific event The association is made. The method of associating the event history with the waveform data is not limited to the method of assigning the identification code, and the specific event recorded in the event history data 63 and the waveform data indicating the driving situation before and after the occurrence of the event, Any method may be used as long as the display control unit 52c can identify the method.

  The display control unit 52c shown in FIG. 3 normally has a blood pressure waveform indicating a patient's blood pressure, an electrocardiographic waveform input from an electrocardiograph, and the like while the balloon control unit 80a is driving the balloon catheter 80. The balloon internal pressure waveform indicating the internal pressure of the balloon is displayed in real time in the waveform display area 54b (see FIG. 5) of the display unit 54. The display control unit 52c receives the operation signal from the input unit 56, and correlates the event history with the contents (waveform) of waveform data such as blood pressure data 64a, electrocardiogram data 64b, and balloon internal pressure data 64c. Can be displayed in the waveform display area 54 b of the display unit 54.

Can be displayed in the comment display area 54a. Further, when the display control unit 52c displays the contents of the waveform data stored in the waveform storage unit 64 in the waveform display area 54b, the displayed waveform is one before and after the occurrence of a past event, and is not a real-time waveform. A caution display 86 (see FIG. 8) indicating a thing can be displayed in the comment display area 54a.

  As described above, the storage unit 60 includes the event storage unit 62 including the waveform storage unit 64 and the temporary storage unit 61, and includes event history data 63, blood pressure data 64a, electrocardiogram data 64b, and balloon internal pressure data. 64c is stored. In addition to these, the storage unit 60 stores explanation display information 66 and control information 68. Information stored in the storage unit 60 is read by the control unit 52. Moreover, the control part 52 can change and delete the information memorize | stored in the memory | storage part 60 as needed. The storage unit 60 is configured by a nonvolatile memory such as a hard disk or a flash memory, but is not particularly limited as long as it can store and update information.

  The monitor unit 50 has an external memory mounting unit 58, and a removable storage medium such as a USB memory can be mounted. The control unit 52 can copy the information stored in the storage unit 60 to the storage medium attached to the external memory attachment unit 58. The monitor unit 50 can communicate with the printer 84, and the user of the IABP driving apparatus 10 can print waveform data and the like as necessary.
