Abstract

PURPOSE:To achieve a quick printing of a desired file, by printing an identification code alone with a quick feed of a data file. CONSTITUTION:When a print command signal is inputted into a printer control microprocessor (MPU)1 from a print mode input section 3, it is sent to an oximeter control section 7 via an interface 6. Data stored in a memory 8 is read on a 3 byte basis sequentially with the first address first to be transferred to the MPU1 via the interface 6. With the MPU1, the data are analyzed and after a graph display processing, the results are outputted to a print head 4 together with a time data to print. When another file is needed in the course of the print processing, with the inputting of a command signal from an input section 3, the MPU1 stops the printing. A file identification code alone is fed quickly from the memory section 8 to print and when a desired file is reached, a printing command is inputted from the input section 3 to complete the quick feed, returning the printer to the normal printing operation. This assures a quick printing of a desired data.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is used in an oximeter that projects light from the surface of the skin and detects the light that has passed through the fleshy tissue to measure the oxygen saturation level in the blood. Regarding printers.

[Conventional technology]

An oximeter measures arterial oxygen saturation in the blood.
It is equipped with a recording device that measures oxygen saturation (sometimes called SaO2) and pulse rate and records it along with information such as the time of measurement, but this type of recording device simply prints out the measurement results. Ta.

[Problem that the invention seeks to solve]

Oxygen saturation is often measured multiple times at intervals, and conventionally, the results of these measurements were printed out each time they were measured.

However, depending on the situation, it may not be necessary to print out all the measurement results, and the latest measurement results, etc.
There is a demand for first printing and examining only the measurement results at a specific time, but conventional recording devices have not been able to meet such demands.

[Means for solving problems]

This invention aims to solve the above problems,
The measuring device is equipped with a storage unit that stores multiple measurement results from different measurement times in multiple file formats, and the printer side selects a specific file stored in the storage unit and prints it. This function allows you to print only the measurement results recorded in a file, and is used in printers that read and print print information from multiple files stored in an external storage device using a read signal from the printer. In response to a print command signal input from a key, multiple files stored in an external storage device are sequentially read and the file contents are printed, and in response to a file fast forward command signal input from an operation key, printing is performed. The present invention is characterized in that it includes a printer control means for sequentially reading out a plurality of files stored in an external storage device and printing only the file identification code.

[Effect]

When a print command signal is input from the operation keys of the printer, the printer control means responds to this signal and prints the print information stored in multiple file formats in an external storage device installed in an oximeter, etc. The files are sequentially read and printed according to the order of the files.

Further, when a file fast forward command signal is input from the operation key, the printer control means stops the printing operation in response to this signal, sequentially reads the files stored in the external storage device, prints only the file identification code, Move to the next file and repeat the above operations. As a result, only the file identification code is printed without printing the file contents, so that the file can be fast-forwarded.

When a desired file is found from the printed file identification code, a print command signal is input from the operation key, and the file fast-forwarding process is completed, and normal printing operation is resumed to print the contents of the file.

The control of the printer described above is executed by a printer control means composed of software executed by a printer control microprocessor.

〔Example〕

Examples of the present invention will be described below.

First, the configuration of the printer control circuit will be explained. FIG. 1 is a block diagram of the printer control circuit. 1 is a printer control microprocessor (hereinafter referred to as MPU), 2 is a main memory, and 3 is a print mode input unit that feeds print paper, prints file contents, This is the part where command signals such as fast forwarding of multiple files are input from the operation keys.

4 is a print head unit, which prints the print data output from MPU 1 on recording paper; 5 is a printer motor control unit, which feeds the printer's recording paper using the paper feed signal output from MPU 1. Control the motor.

On the other hand, to explain the configuration of the oximeter side connected to the printer control circuit, 7 is an oximeter control section consisting of a microprocessor, and 8 is a storage section (RAM) for temporarily storing the results processed by the oximeter control section 7. ) and
9 is a probe for detecting oxygen saturation in blood; 10
is a probe that detects pulse.

The data detected by the probes 9 and 10 is processed by the oximeter control unit 7 and stored in the storage unit 8 together with time data output from a clock mechanism (not shown).

The data stored in the storage section 8 is output from the MPU 1, read out in response to a read signal input to the oximeter control section 7 via the interface 6, and transferred to the MPU 1 via the interface 6.

Next, the contents and format of the data stored in the storage section 8 will be explained based on FIG. 2. Here, it is assumed that data is stored from address 6000 in the storage section. It is also assumed that address 1 has a capacity of 1 byte. Address 6000 stores a code indicating the year data, for example FFH (H is a hexadecimal symbol), address 6001 stores the file number, for example FileO, and address 6002 stores the year, for example the last two digits of the year 1986. is stored. Address 6003,
By address 96005, there is a date code indicating date data,
For example, the FEH and month/day, such as January 1st, are stored. 6
From address 006 to address 6008, a time code indicating time data, for example FDH, and time, for example 0:00 are stored. After address 6009, measurement information is stored in units of 3 bytes. In this example, the oxygen saturation level is 9 at address 6009.
6%, pulse rate 64 is stored at address 600A, and no warning information is stored at address 600B.

When the power is turned on, the first 9 bytes of data described above are always stored as file identification information, and from then on, the measured oxygen saturation, pulse rate, and a warning that is issued when the measured value exceeds the allowable standard range are stored. Information is stored. These measured values etc. are stored every 5 seconds, for example.

Next, an overview of the operation of the printer control circuit shown in FIG. 1 will be explained. First, when feeding print paper, that is, inputting a paper feed command signal for the printer from the print mode input section 3 consisting of operation keys, the MPU 1 issues a paper feed command to the printer motor control section 5. 1 piece of printing paper
Send by line. Also, from the print mode input section 3, the MPU
When a print command signal instructing to print the file contents is input to 1, this command signal is sent to the oximeter control section 7 via the interface 6. and storage section 8
The data stored in the memory is read out sequentially in 3-byte units starting from the first address, and sent to the MPU via the interface 6.
It will be forwarded to 1. The MPU 1 analyzes these transferred data and outputs the year, month, and date as is to the print head 4 and prints them, and the measurement data is processed to display a graph and output to the print head 4 along with the time data. and print.

If you want to check a file with a different date and time during the printing process, input a paper feed command signal from the print mode input section 3. This signal is also a fast-forward command signal for the file, so the MPU 1 receives this command signal. The printing operation is stopped and the next data is read from the storage section 8. If this data is the next file identification code, that is, the first year code, only this year code and identification code such as the file number are printed, and the process moves on to the next data reading operation without printing other data. In this way, only the file identification codes are printed one after another. This allows the file to be rapidly forwarded without printing the file contents.

When the desired file is found from the printed file identification code, a print command signal is input from the print mode input section 3, and fast forwarding of the file is completed, and the normal printing operation described earlier is resumed and the file contents are printed. be done.

Figure 3 is an example of a printout, where the date, file number, graph scale, etc. are printed at the top, and the measurement results are shown as a graph with the time on the vertical axis and the measured value on the horizontal axis. ing.

Next, the control of the print operation processed by the MPU 1 will be explained based on the flowcharts shown in FIGS. 4 to 6.

FIG. 4 is a flowchart showing an outline of the file printing operation. In step S1, it is checked from the print mode input unit 3 whether a key to command paper feed has been pressed, and if it has been pressed, the paper is fed by one line. The process is executed (step S2), and the process returns to step S2 to enter the next processing cycle. If the key for instructing paper feeding is not pressed in step S1, the process moves to step s3, and it is checked whether the print file key for instructing printing of file contents has been pressed. If the key is pressed, the print process of the file contents is executed (step S4), and the process returns to step s2.

If no key is pressed in step S3, the process immediately returns to step S2 and the next processing cycle begins.

Next, the file content printing process shown as step S4 in the flowchart shown in FIG. 4 will be explained with reference to the flowchart shown in FIG.

First, a print instruction command of the file contents is output to the oximeter control section 7 and the paper feed flag is reset (steps 510, 5ll), and three bytes of data stored in the storage section 8 are received (step 512).

Check whether the received data is an end code (step 3)
13) If the code is an end code, the process returns to the main routine, but if the code is not an end code, it is checked whether it is a year code (step 514). If it is a year code, the year data is printed (step 515), and the process returns to step S12. Since the second byte of the year data also includes the file number, the file number can be printed along with the year data. Step S1
If the result of determination in step 4 is that it is not a year code, check whether it is a date code (step 516), and if it is a date code, print the date data and print the scale axis for graph printing (step 517). Return to S12. If the result of the determination in step S16 is that it is not a date code, it is checked whether it is a time code (step 518), and if it is a time code, the time is printed (step 519), and the process returns to step 512.

As a result of the determination in step 518, if it is not a time code, this is measurement result data and warning information. Therefore, these data are not printed when fast forwarding of the file is commanded. Therefore, the process proceeds to step S20, and it is checked whether the paper feed flag set by the file fast forward command (this flag is set in the process of graph data print processing, which will be explained later) is set (=1). If not set, a graph conversion calculation is performed to calculate the print position of a dot for displaying the measurement results in a graph, and the graph data is printed (step S21.522). The printing process of graph data will be explained later.

When the printing process of the graph data is completed, the paper feed flag may be set during this process, so it is checked whether the paper feed flag is set (step 323).
), if the flag is not set, the process returns to step S12, but if it is set, 3 bytes of data are received from the storage unit 8 (step 524), and it is checked whether this is a year code (step 525). If it is a year code, the process moves to step S15 and the year code is printed. Further, if the result of the determination in step S25 is that it is not a year code, it is checked whether it is an end code (step 526), and if it is an end code, the process moves to step S24 because it is the main code.

As a result of the determination in step S20, if the paper feed shift flag is set, fast forwarding of the file has been commanded, so the process moves to step S24.

Steps S24 and 826 are steps for fast-forwarding the file, and when the paper feed flag is set, the file contents are fast-forwarded without printing until the year code is found, allowing the desired file to be quickly viewed. The attachment can be issued.

Next, the graph data printing operation shown as step S22 in the flowchart shown in FIG. 5 will be explained with reference to the flowchart shown in FIG.

It is assumed that in step S21 of the flowchart shown in FIG. 5, the print position at which the data is plotted from the print data is calculated for each print string (in the time axis direction). First, the print string counting counter is reset to n=0 (step 531). The paper feed motor is started (step 532), and it is checked whether the print head is located at the printing position of the nth column (initially n=0) (step 5).
33), if it comes to that position, the nth
The second column of printing is printed, and n is incremented to n+1 (step S34.535). It is checked whether n has reached the value set as the end value (step 836), and if not, the process returns to step S33 and the above process is repeated. As a result of the determination in step S36,
When the end value is reached, the paper feed motor is stopped (step 537) and the process returns to the previous routine.

As a result of the determination in step S33, if the print position of the n-th column has not yet been reached, the process proceeds to step S38, where it is checked whether a key for instructing paper feeding has been pressed. When pressed, as explained earlier, this means a command signal to fast-forward the file, so the paper-feed flag is set (step 539), and the process moves to step S33. Further, as a result of the determination in step S38, if the key for instructing paper feeding has not been pressed, the process returns to step S33.

Stopping the fast forwarding of a file can be realized by detecting the OFF state of the paper feed key in this way, but it can also be realized by resetting the paper feed shift flag in accordance with the manual input of another key.

〔Effect of the invention〕

As explained above, according to the present invention, when printing measurement data, it is possible to fast-forward the data files and select and print only the desired data file, so that the desired data can be printed quickly. Not only is this possible, but if the printer is battery-powered, it can reduce battery consumption and save printing paper.
