Description

Detailed Description of the Invention (Technical Field) The present invention relates to a processing device for measurement data obtained by an automatic blood analyzer that performs biochemical analysis or immunological analysis, and particularly relates to a processing device for measurement data obtained by an automatic blood analyzer that performs biochemical analysis or immunological analysis. The present invention relates to a data processing device for an automatic blood analyzer having a measurement accuracy management function.

(Prior Art) As is well known, an automatic blood analyzer dispenses a required amount of reagent corresponding to a measurement item into a serum sample, causes the two to react, measures the reaction state by an appropriate means, and records the measurement data. It is configured to display the measured data on the display and to print and record the measured data one by one on the printer.

By the way, in the past, these measurement data were used only to show the measurement results to doctors, etc., so generally, the measurement data was not recorded and saved in a microcomputer, but instead was simply recorded on a printer. It is. In other words, an enormous amount of measurement data is collected per day by an automatic blood analyzer, and storing all of this data one by one in a microcomputer increases the size of the device, especially when using a so-called multi-channel blood analyzer that can measure multiple items simultaneously. It is virtually impossible for an automatic analyzer to store all of these.

Conventionally, the measurement accuracy of measurement data from an automatic blood analyzer was managed by an inspector picking up measurement data that seemed to be abnormal from among all the measurement data recorded and displayed on the printer. The current method is to discover abnormalities in the automatic blood analyzer based on the measured data.

However, when controlling the measurement accuracy of an automatic blood analyzer using such a method, as mentioned above, the inspector must select from among the huge amount of measurement data the problems that appear to be caused by an abnormality in the automatic blood analyzer. Since the measurement data must be picked up and examined, the work involved is extremely complicated, and improvements in this area have been strongly requested.

(Object of the Invention) The present invention has been devised in view of the current situation, and its purpose is to determine the state of reaction to measurement items from among the measurement data obtained by an automatic blood analyzer. By automatically saving only the measurement data necessary as measurement accuracy control data for the analyzer, this type of work by inspectors can be made extremely easy, and the amount of measurement data to be saved is small, so the storage capacity is small. It is an object of the present invention to provide a data processing device for an automatic blood analyzer that can be sufficiently handled by a microcomputer and is easy to operate without the risk of increasing the size of the device.

(Structure of the Invention) In order to achieve the above object, the present invention dispenses a required amount of a reagent corresponding to a measurement item into a serum sample, causes them to react, and displays the reaction coloring state as a time course. , a data processing device for an automatic blood analyzer configured to record, the data processing device including a memory circuit that stores and holds a time course of measurement data, and a memory circuit that stores and holds a time course of measurement data; Compares the time course of the measurement data with the time course of the reference data input into the microcomputer to determine whether the time course of the measured data is within the allowable range of the time course of the reference data or includes data values outside the range. a range circuit for enlarging the time course of the measurement data, a monitor device for displaying the output of the range circuit, and a recording device for recording the time course of the measurement data; If all data values of are included within the allowable range of the time course of the reference data, then
It issues a command to delete the time course of measured data from the memory circuit, and is configured to retain the time course of the measured data in the memory circuit if the standard data time course contains an abnormal value outside the allowable range. be.

(Embodiments) The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

The blood analyzer according to this embodiment irradiates a corresponding serum sample 1 into which a reagent corresponding to a measurement item has been dispensed with measurement light l of a predetermined wavelength, and calculates the amount of change in absorbance (OD value) due to the serum sample 1. The light receiving element 2 converts the voltage and the amplifier 3 amplifies the voltage.

The measurement data colorimetrically measured in this way is
The data is input to data processing device A.

This data processing device A includes a logarithmic converter 4, an A/D converter 5 that converts measurement data input to the logarithmic converter 4 into a digital signal, a memory circuit 6 that stores this digital signal, and a memory circuit 6 that stores this digital signal. A data judgment circuit 8 that compares the time course of the measurement data stored in the memory circuit 6 with reference data inputted in advance to the microcomputer 7, and a range circuit 10 that enlarges and displays any part of the measurement data. , a monitor device 11 that displays the time course of the same measurement sample for each same measurement sample after the measurement is completed;
and a recording device 12 that records the time course of the same measurement sample for each same measurement sample after the measurement is completed.

The memory circuit 6 includes a holding circuit (not shown) for holding measurement data measured a plurality of times for each of the same measurement specimen and processing the data as a time course.

As described above, the data judgment circuit 8 compares the time course of the measurement data recorded in the memory circuit 6 and the reference data inputted in advance to the microcomputer 7. The comparison operation of circuit 8 is performed as follows.

The reference data X input into the microcomputer 7 in advance is input so as to be displayed as a band-shaped time course as shown by the dashed line and diagonal lines in FIG. In this way, the reference data It is obtained by linearly connecting the upper limit value for each measurement time and linearly connecting the allowable lower limit value for each measurement time. This is to determine a range that serves as a guideline for determining that the measured data value is normal if it is between the upper and lower permissible limits, and abnormal if it is not between the upper and lower permissible limits. Of course, it is assumed that the measured data values within this band-shaped time course are within an acceptable range that is considered medically safe.

Next, among the time courses of the measurement data stored in the memory circuit 6, all measurement data values are
As shown in the figure, if the data is within the range of the reference data X (hereinafter referred to as measurement data Y ₁ ), the data judgment circuit 8 judges the measurement data Y ₁ to be normal data,
Based on this determination, the circuit 8 issues a command to display the time course of the measurement data _Y1 on the monitor device 11, and prints and records the time course via the recording device 12. A save/delete command for _Y1 is issued to the memory circuit 6. As a result, the measurement data _Y1 storage is deleted from the memory circuit 6.

Furthermore, if the time course of the measurement data stored in the memory circuit ₆ includes data values outside the _range of the reference data Based on this determination, the circuit 8 issues a command to display the time course of the measurement data _Y2 on the monitor device 11, and also issues a command to display the time course of the measurement data Y2 on the recording device 1.
2, the time course is printed and recorded, and the same circuit 8 sends the memory circuit 6 to store and maintain the measurement data _Y2 . As a result, the measurement data _Y2 is stored in the memory circuit 6. Patterns of this abnormal data include analysis value data outside normal, linear judgment data, and OD value (optical
There are things that go beyond deusity.

As described above, the range circuit 10 can enlarge any part of the measurement data, display this enlarged state on the monitor device 11, or input the enlarged data to the recording device 12 in order to print the same state. This is especially useful for reducing the labor of inspectors regarding abnormal parts of abnormal data.

Therefore, in the data processing device A according to this embodiment, since it operates as described above, the measurement data stored in the memory circuit 6 is only the measurement data Y ₂ determined to be abnormal. Even if the capacity of the memory circuit 6 is not so large, sufficient storage can be achieved. In addition, the inspector prints only the abnormal data accumulated in the memory circuit 6 on the recording device 12 at a later date, enlarges the abnormal part on the monitor device 11, and visually checks it to determine whether the abnormality is due to biological causes or mechanical causes. This makes it easy to determine whether the problem is caused by

(Effects of the Invention) According to the present invention, only the abnormal data can be enlarged and visually confirmed, and can be printed out using a recording device, so it is possible to easily discover whether it is an abnormality in the serum sample or a machine failure. It has the effect of being able to
