Abstract

PURPOSE:To confirm a desired data simply and quickly with a specific living body information processing unit by storing the living body information collected by each connected living body information processing unit into a storage means in a specific living body information processing unit while being updated continuously. CONSTITUTION:The data of a living body information storage area of its own equipment is updated into the newest collection data and the processing data is stored in a prescribed area and the data stored in a prescribed area is transferred to a prescribed RAM 3 area of a master station monitor (central monitor) 510 automatically. Thus, even when the central monitor 510 desires to display the living body information from the collection floor at each other connection monitor switchingly, the display data has only to be read sequentially from a prescribed area in the RAM 3 in its own equipment simply. Thus, even when the central monitor 510 being a master station confirms the collected data by each connection monitor, the control is simplified and slight access time is enough.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention connects a plurality of biological information processing devices to each other via a communication medium, The present invention relates to a biometric information processing system that allows confirmation of biometric information collected by a processing device.

[Conventional technology] In recent years, with the development of semiconductor technology, small and inexpensive
Many computer-based products have appeared, and communication systems in which computers are connected to each other via communication media have been developed.

For this reason, the use of computers in hospitals is progressing, and systems are being developed that automatically perform measurements, especially for patients whose condition requires constant monitoring, and automatically transfer the measurement results to a monitoring room or center room. are also appearing.

Even in such a system, for example, a communication system that transfers measurement data from the bedside to a monitoring room, center room, etc. via a communication medium, the communication method used in general-purpose computers is directly applied to the transfer process.

[Problems to be Solved by the Invention] For this reason, if the same communication control method as used in these general-purpose computers is used, data from multiple communication devices cannot be uniformly communicated among the devices, and data from specific devices cannot be communicated uniformly. Situations such as increased communication volume occurred, and it was not possible to perform appropriate processing while checking the measurement status of each device.

Furthermore, data collected from living bodies is always collected at regular intervals. It is often necessary to check this collected data at any time in a monitoring room or the like.

However, if all the requested data is transmitted only after a request is made from the monitoring room, etc., it will take a long time until the requested data is actually transmitted and can be confirmed by the monitoring room, etc. Furthermore, communication control during this time also becomes complicated.

Furthermore, when trying to simultaneously check the state of a living body being collected from all connected devices, it is necessary to request each device to send the collected data in turn, which speeds up the access time. requires very high-speed communication, and requires very complex and large-scale communication control.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and includes the following configuration as a means for solving the above-mentioned problems.

That is, the biometric information processing system connects a plurality of biometric information processing devices to each other via a communication medium, and allows at least one first biometric information processing device to check biometric information collected by other connected biometric information processing devices. The other connected biometric information processing device stores the collected biometric information collected from the living body.
and a transmitting means for sequentially transmitting information in a predetermined collected biometric information storage area of the first storage means to the first biometric information processing device at a predetermined period, the first biometric information processing device , at least a receiving means for receiving collected biometric information sent at predetermined intervals from connected biometric information processing devices in various places, and a second receiving device for storing the received information received by the receiving means in a predetermined area allocated for each device. storage means.

Alternatively, there is a biological information processing system in which a processing device main body and each input/output portion are connected to each other, and the processing device main body includes a first storage means in which a predetermined storage capacity is allocated to each input/output portion. , receives transmission information sent at predetermined intervals from connection input/output parts in various places, and stores it in an allocated area of the first storage means corresponding to the source input/output part of the received transmission information of the first storage means. a first receiving storage means for;
a first transmitting means for reading connection input/output section address information stored in the first storage means from a corresponding allocated area and transmitting the information to the input/output section; a second storage means for storing usage information;
a second reception/storage means for receiving transmission information sent at predetermined intervals from the processing device main body and storing it in a corresponding area of the second storage means; and second transmitting means for reading out information and transmitting it at predetermined intervals.

[Function] In the above configuration, the transmission of data from each device at regular predetermined intervals is ensured (required for complicated communication control procedures), and the information in a predetermined area in the storage means of each biological information processing device is simply By simply controlling the transfer of stored information to a specific biometric information processing device, the collected biometric information of each connected biometric information processing device can be reliably and efficiently (continuously updated to the storage means in the specific biometric information processing device). Therefore, if you want to check the data normally collected by each device using a specific biometric information processing device, you can simply store it automatically without any need for communication control with biometric information processing devices in various locations. It is only necessary to read the stored data from the corresponding device area in the storage means of the device, and the desired data can be checked very easily and quickly.Furthermore, it is completely unaffected by control operations, etc. in each device. Therefore, a specific biometric information processing device can independently process any collected information without any increase in communication load, without considering the control of other biometric information processing devices.

In addition, input/output information can be transferred between each input/output part of the biological information processing device and the main body of the processing device by simply controlling the transfer of stored information. It can be done with

RAM3 of the central monitor 510 having the above configuration
FIG. 3 shows an example of the collected information storage area allocated to each slave station in the mobile station.

In this embodiment, one central monitor device is configured to be able to collect biological information (electrocardiogram information) for up to 12 beds.

Reference numerals 521 to 525 in FIG. 3 are collected data storage areas allocated to each bed of each slave station, and in this embodiment, a capacity of 2100 bytes for one bed is allocated. This is an area where information is stored, excluding waveform information, among a series of biological information collected at each bedside.Specifically, information about the patient, status information of the monitoring device, heart rate, etc. , respiration rate, blood pressure value, body temperature, ambient temperature, etc. are stored.

Further, 526 is a waveform storage area, which is an area in which a slave station to which a waveform transmission request is sent stores requested waveform information. 527 and 528 are storage areas 1 and 2 for output data to the thermal printer 511, and 529 is a storage area for information collected from the input box 512.

Storage area 582°585.588,591. and waveform storage areas 583 and 58 for storing collected waveform information for each floor.
It is composed of 6°589.592. This waveform storage area contains, for example, electrocardiogram waveform trends,
A template, ST, PV convex curve, waveform (Co) representing cardiac output, etc. are stored.

Note that the above area allocation is the maximum one, for example,
If the number of subjects to be measured is only for one bed, area allocation is also for only one bed, and other areas are used for other purposes.

Further, 593 and 594 refer to the connected thermal printer when a thermal printer is connected, or the thermal printer 511 connected to the central monitor 510.

In this embodiment, only (one) guidance cord for one bed is actually connected to each slave station monitoring device, and the RAM 3 of the central monitor 510 has an area for storing collected information for a maximum of 12 beds. However, only a storage area for one floor is allocated to the RAM 3 of each slave station.

Therefore, the information transfer timing from each slave station, which will be described later, is also
The setting is based on this 12-bed case.

The control of a general patient monitoring device having the above configuration is substantially the same as the control disclosed in Japanese Patent Application No. 1-120424 filed on May 16, 1989 by the applicant of the present invention. Therefore, the storage control and communication control of collected biological information specific to this embodiment having the above configuration will be explained below.

In this embodiment, the communication form between the central monitor 510 and each other device can be roughly divided into two types:
There are three types of communication: (1) communication with the thermal printer 511, (2) communication with other slave station monitors.

Communication with the input box 512 is as follows: (1) From the input box 512 to the central monitor 510
Considering that the collected information is mainly waveform information, data is transferred to the input box area 529 in RAMB approximately every 5 mS.
is stored by DMA transfer. Further, the transfer of the data may be notified at the same timing, for example, by an interrupt or the like.

(2) Input box sending 12 from central monitor 510
Transmission to is performed approximately every 60m5. This transmission is mainly the transmission of control codes and the like.

Communication with the thermal printer 511 in (1) The transmission from the recorder output data storage area of the central monitor 510 to the thermal printer 511 is based on the fact that the transmitted data is mainly print-out information and considering the print speed, etc. The recorder output data area 527 in RAMB,
If there is output data on 528, DM approximately every 60m5
Output by A transfer.

(2) Central monitor 5 from thermal printer 511
Transmission to 10 is performed approximately every 100 m5. This transmission is mainly transmission of status information and the like.

Central monitor 510 for waveform information etc. in communication
Data other than the data stored in the collected data storage areas 521 to 525 allocated to each slave station bed in the RAM 3 is transmitted and received according to a predetermined communication control procedure when necessary according to polling from the central monitor 510. This communication control procedure is substantially the same as that of Japanese Patent Application No. 1-178028 previously filed by the applicant.

In the communication (2), communication from each slave station monitor to the central monitor 510 is performed approximately every 0.48 seconds. This communication transfers the waveform information in the RAMa of each slave station (for example, the data in the area indicated by the reference numeral 582 in FIG.
The data is transferred to predetermined areas 521 to 525 in the figure.

In this embodiment, no special communication control procedure is adopted for each of the above-mentioned memory transfers, and data in a predetermined memory area of each configuration is transferred to the transfer destination memory, which is extremely easy to control and capable of high-speed transfer. The configuration is such that the data is simply transferred to a predetermined area.

Specifically, a predetermined area in the RAM 5 is allocated to each monitor device, thermal printer, and input box, and
A DMA request is outputted to the transfer source device at each predetermined period described above so that the respective configurations do not overlap, and high-speed DMA memory transfer control is performed between CPUI processes.

By controlling in this way, two sets of all (the same data) are stored at the same time between the image configurations.However, complicated communication control related to transfer control of collected data is not required, and There is no need to read the necessary data from the transfer source memory every time the data is needed and then transmit it to the transfer destination using complicated transfer control.

In addition, even at the device development stage, by using the configuration of this embodiment as described above, since the image configurations have common data, there is almost no need for coordination between the image configurations in program development, and each image configuration can be developed independently. This makes debugging very easy.

Furthermore, even if the number of connected monitors changes, there is almost no effect on communication control procedures, etc., and expansion or reduction of the system can be handled very flexibly.

Each monitor device is controlled as a general patient monitoring device, and performs predetermined processing on biological information periodically collected from the input box 552, etc. for display/output on its own device, and removes waveforms. Data including each analysis result is stored in a non-waveform data storage area (582, etc.) for each floor, and waveform data is stored in a waveform data storage area (583, etc.). When various processing using the stored data is required, the necessary data is read from the data storage area and processed. For example, when displaying predetermined waveform data on a monitor device, the selected waveform data is read out, developed into a display pattern, and displayed. During this process,
No special processing is required for controlling the transfer of the stored data to the master station monitor device.

In this way, by simply updating the data in the biometric information storage area of the own device to the latest collected data and storing the processed data in a predetermined area, the data stored in the predetermined area is automatically transferred to the master station monitor device. Even if the central monitor 510 wants to switch and display the biometric information collected from the collection floor of each connected monitor, the data will be transferred to a predetermined RAM area. It is sufficient to read out the display data sequentially. In this way, even when you want to check the data collected by each connected monitor on the central monitor 510, which is the master station, there is no need for complicated communication controls, which not only simplifies control but also reduces access time. It can be made very small.

FIG. 5 shows an example of the memory transfer interval between each of the above configurations.

Through the above processing, optimal information transfer control can be performed for the system of this embodiment that analyzes electrocardiogram information. That is,
The latest collected data from a living body, such as electrocardiogram information, which is generated regularly at regular intervals, can be reliably transferred to the central monitor 510 or the like with extremely simple control.

As explained above, according to this embodiment, the master station simply reads out the biometric information collected from each connected biometric information processing device, which is updated at a constant cycle, from the storage means without using any special communication control procedure. It can be output with . If you want to output collected biometric information that is not stored in the storage means, you can collect the requested information by outputting a request to send the information, and with very simple control,
The biometric information collected by each biometric information processing device can be output accurately and quickly.

Therefore, even in cases where transmission data is periodically generated and urgent transmission is required, such as with a biological information measuring device installed at each bedside, it is possible to appropriately respond and provide optimal treatment.

Further, although the above description has been made regarding an electrocardiogram information collection/analysis device, the present invention is not limited to the above example (and can be applied to any biological information collection/monitoring/processing device).

Furthermore, it goes without saying that the present invention can be applied not only to all biological information processing devices but also to information processing devices that require general data communication. It is especially suitable for devices that generate transmission data at regular intervals.

Furthermore, although the above description has been made regarding an example in which the collected data from each connected monitor device is transferred to one central monitor 510, there may be two or more.

The present invention is not limited to the above examples (various applications are possible).

[Effects of the Invention] As explained above, according to the present invention, collected data can be updated at regular intervals and stored in the first biological information processing device and the second biological information processing device, and the collected data can be updated periodically. It is possible to reliably and efficiently transmit and store transmission data that is generated over time using extremely simple control. Therefore, each device can process the collected data completely separately.

In addition, input/output information can be transferred between each input/output part of the biological information processing device and the main body of the processing device by simply controlling the transfer of stored information, making the data transfer control of the device extremely simple. It can be done with

Therefore, it is very easy to develop the device, and it is possible to flexibly respond to changes in the system.
