Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a biometric information processing device that collects and processes biometric information from a subject, and for example, selects a biometric information collection module that is optimal for the subject to be examined. The present invention relates to a biological information processing device that can collect various types of biological information from a subject simply by attaching it to an arbitrary position.

[Prior art] In recent years, the number of test objects (
There are many types of test items), and there are many requests to increase the number of test subjects that should be collected at one time.

However, for each test, patient information must be collected using a unique measurement terminal for each test. Then, each measurement terminal or each specific type of measurement terminal is connected to the processing device section via a unique biological information collection module.

Furthermore, each measurement terminal and the biological information collected from the measurement terminal are analog signals, and when processed by a processing device, it is necessary to convert this into a digital signal.

[Problems to be Solved by the Invention] However, conventionally, the position (connector) to which the biological information collection module of the device is connected is determined in advance for each module, and it is not possible to connect it to any other position. For this reason, the types and number of modules that can be connected are also subject to significant restrictions.

Furthermore, the collected signals are converted into digital signals within each module, which means that one device has a large number of redundant digital converters, which is wasteful.

In order to avoid this, some devices import analog signals from each module into the main body of the device, switch the analog signals of each module using a switch, etc., and connect them to an analog digital converter inside the device for conversion. This method would prevent wastage of Anaguchi digital converters, but it would require routing as many analog signal lines as the number of modules.

[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 biological information processing device is capable of mounting a plurality of subject information collection modules for inputting subject information, and includes a module mounting means capable of mounting the plurality of subject information collection modules at arbitrary positions. , a determining means for determining the mounting position of the module mounting means, and a control means for controlling the desired subject information collection module according to the positional information determined by the determining means.

[Operation] In the above configuration, the collected analog signals from each subject information collection module are connected to each module mounting means through a common signal line, and are converted into digital signals by an analog-to-digital converter provided in the control means. will be processed.

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

In this embodiment, any biological information can be collected, and by changing the type of unit attached to the input box 30, which will be described later, all kinds of biological information can be collected.

FIG. 1 is a block diagram of an embodiment according to the present invention, and in the figure, l is a CPU stored in a ROM 2, which controls the entire embodiment according to the program shown in FIG. In addition to the program, a ROM stores fixed parameters used in this embodiment, 3 is a RAM for temporarily storing processing progress, etc., and 4 generates an interrupt when a key is pressed from the operation unit 20. Let CPU 1
an interrupt controller (PIO) that performs interrupt control for interrupt requests from other sources;
Reference numeral 5 designates a transmission interface that controls the interface with the network control unit 40 when performing transmission with other devices via the communication network 500 to which the device of this embodiment can connect, and 10 designates a display unit, which in this embodiment is a liquid crystal display. Equipped with a display device. Reference numeral 20 denotes an operation unit, and 30 an input box to which various biological information collection units can be attached. In this embodiment, six units, module AIIO to module F160, can be attached. 4o is a network control unit that controls transmission with a communication network 500 to which the device of this embodiment can be connected, and 50 is a network control unit that controls transmission with a communication network 500 to which the device of this embodiment can be connected; This is an analog-to-digital converter (A/D converter) that converts an analog signal into a digital signal that can be processed by the CPU 1, and includes an analog converter 51. Also, 110~
Reference numeral 160 indicates a module ANF attached to the input box 30, and reference numerals 111 to 161 indicate measurement units attached to each module ANFllON160. These measurement units 111 to 116
Each has a guidance cord that collects biological information from the subject, and the tip has a sensor for measurement, for example. In this embodiment, the arrangement of each signal line in the connector section of each module is common to all modules, and the measurement analog signal is also output to the analog bus common to the others. Therefore, the measurement analog signals from each unit module are sent to the A/D converter 5o in a time-division manner.

Even if this time-division output is a time-division output in which each module is output during a pre-allocated time, C
It may be a time-division output in which the unit module that receives the output instruction command from the PU1 outputs the output for the permitted time.

Input box 30 of this embodiment having the above configuration
FIG. 2 shows details of the distribution of signal lines in each module connection connector section.

In FIG. 2, UDO-UD7 of bins 1-8 are digital data signals O-7, bins 19.20 are their ground lines, bins 9-12 are address data signals O-3, and bins 23.2
4 is the ground wire, Bin 13 is the memory read control signal, Pin 14 is the memory write control signal, Bin 16 is the reset signal line, Bins 18, 21 and 22 are the DC power lines, and Bin 25 is the common analog from each measurement terminal. MPX which is the output signal line
OUT signal line, pin 27 is BPOUT signal line, pin 28
is an ECGOUT signal line, and bin 30 is an interrupt request (include request) signal line.

Each of the above signal lines is a common signal line for each module,
No matter which module the unit is inserted into, the same signal lines will be connected.

In addition to the common signal lines mentioned above, there are bins 15 and 17 as signal lines specific to each module. Bin 15 is the selection signal line (sp) of each unit, and bin 17 is the enable signal line of each unit. .

Then, the unit to which the "talent" signal line of each unit selection signal line is connected can occupy each data path. In addition, the enable signal line is turned "on" when the units installed in each module ANF110 to 160 are in an operable state, and whether there is a unit installed in a module such as CP01, whether the unit is operational or not. We are informing you that The biological information collection process of the apparatus of this embodiment having the above configuration will be explained below with reference to the flowchart of FIG. When the power is turned on to the apparatus, initialization processing is executed in step S1, and then, in step S2, the apparatus waits for a measurement start instruction to be input from the operation section 20.

When a measurement start instruction is input, the process moves from step S2 to step S.
Proceed to step 3 and read the status from the units installed in each module. This reading may be performed for the module whose enable signal is "enabled". Then, the type of unit installed in each module and the operating state of this unit are checked and registered in a predetermined area of the RAM 3 in step S4. In the following step S5, the status of each unit is checked using the status signal, and in step S6, the necessary units are activated and collection of biological information is started from the measurement sensor provided in the unit.

Then, in step S7, the time-sharing measurement data transmission timing is specified, and in step S8, the A/D converter 50
, converts the analog signals sent from each unit into corresponding digital signals, and outputs them to the CPU bus at a predetermined timing, as shown in step S9. In step S10, the CPU 1 takes in this digitized measurement data and executes biological information processing. Continuation In step sti, it is checked whether the measurement process has ended or whether a measurement end instruction has been input from the operation unit 20. If the measurement has ended, the process returns to step S2, and if the measurement is to be continued, the process returns to step S9.

In addition, although the above explanation has been given for an example in which the analog signal from each unit is output during a predetermined time-sharing time allocated to its own unit, the present invention is limited to the above example. Instead, if this time division time is not changed at all midway through, the process of step S7 becomes unnecessary.

In addition, when controlling the units installed in each module to give analog signal output permission when the timing for processing by the CPUI comes, the process of step S7 is not necessary, and each unit receives the output permission command from the CPUI. It is only necessary to output measurement data through detection and control the output of this signal to be stopped when an output stop command is received. In the present invention, the output timing of this analog signal may be arbitrary, and may be any method as long as it does not overlap and output at the same time as other units.

As described above, in this embodiment, a unique unit code is assigned to each unit type, and the installed unit type can be determined by checking this unit code in the status.

FIG. 4 shows the types of units that can be installed in the device of this embodiment and the unit codes of each unit.

As shown in FIG. 4, all kinds of biological information collection units can be attached, making it highly versatile.

In this embodiment, by simply inserting a desired unit among these various biological information measurement units into an empty module, the measurement data from the unit is automatically sent to the CPU1 for processing. Display section 1
0 can be displayed.

The measurement data output from each unit may be sequentially sent to the A/D converter in the above-described time division manner. In this way, in this embodiment, the analog measurement signal from each unit is connected to the MPXOUT signal (bin 2) which is a common analog signal line.
8), and this MPXOUT analog signal is
/D converter 50 converts it into a corresponding digital signal,
Can be output to the CPU bus.

Therefore, unlike the case where each unit is provided with an A/D converter, many A/D converters are not required, and only one A/D converter is required. Furthermore, analog signal lines from each unit do not require unique signal lines for each unit, which simplifies control.

[Effects of the Invention] As explained above, according to the present invention, the collected analog signals from each subject information collection module are connected to each module mounting means through a common signal line, and the analog-digital signal provided in the control means Since it is converted into a digital signal and processed by a converter, the number of signal lines is reduced and the configuration is simple.Measurement results can be confirmed immediately by monitoring a single signal line. etc., it can be made into a highly reliable device.

Furthermore, there are no restrictions on the mounting position of each subject information collection module, and a highly versatile device can be provided.
