Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a liquid level display device in an automatic analyzer, and particularly to a liquid level display device in an automatic analyzer that allows easy visual confirmation of the remaining amount of blood samples, reagents, etc. The present invention relates to a quantity display device.

[Prior Art] As is well known, some automatic analyzers are equipped with a device that determines the remaining amount of blood samples, reagents, etc. set in the automatic analyzer. It is usefully used for management and operation management.

Devices that measure the remaining amount of blood samples, reagents, etc. are conventionally known as devices that use electrodes or devices that measure optically, but in the case of the former, the electrodes are Calculate the position in contact with the surface, and in the case of the latter, calculate the position where a difference in light intensity conversion voltage occurs using a potentiometer, etc., and calculate these calculated values, that is, the residual liquid. Currently, quantitative values are displayed numerically on display devices such as CRTs.

[Problems to be solved by the invention] However, in the case of a liquid volume display device in an automatic analyzer that displays liquid volume using conventional numbers, it is difficult to tell how much liquid volume has decreased in each container. After the worker reads each container's remaining quantity number one by one,
The replenishment status of the liquid in each container must be managed, and this management is not only very complicated and easy to make mistakes, but also requires great skill.

[Means and actions for solving the problem] This device was devised in view of the current situation, and its purpose is to make it easy for the operator to check at a glance how much liquid is decreasing in each container. An object of the present invention is to provide a liquid volume display device for an automatic analyzer, which can be used to check blood samples and reagents in this type of automatic analyzer, and can therefore manage the supply of blood samples and reagents in this type of automatic analyzer very easily and accurately. It is.

In order to solve this purpose, this invention detects the liquid level contained in each container, calculates the height of this liquid level, and displays the amount of remaining liquid in each container. The technical premise is a liquid volume display device in an automatic analyzer that is configured to display the following data: In addition to being displayed on the display device, each bar graph is configured to display the replenishment limit amount, which differs for each container, in different colors, allowing the operator to easily check at a glance how much liquid is decreasing in each container. It was made so that it could be done.

[Example] Hereinafter, this invention will be described in detail based on an example shown in the accompanying drawings.

As shown in FIG. 1, the liquid volume display device A in the automatic analyzer according to this embodiment is used to measure the liquid volume in the reaction measurement tube and the reagent volume in the reagent container (hereinafter referred to as container B). A measuring device 1, an A/D converter 2 that converts the liquid level height signal measured by the liquid level measuring device 1 into a digital signal, an interface 3, and calculates and stores these data signals. It consists of a microcomputer 4 and a display device 5, such as a CRT, which displays the amount of remaining liquid in each container in the form of a bar graph according to command signals from the microcomputer 5, as shown in FIG. There is.

The liquid level measuring device 1 may be of a liquid contact type using known electrodes or a liquid non-contact type using optical measurement as shown in FIG. Based on the determined liquid level height, the amount of remaining liquid in the container is calculated using a known calculation method.

The remaining liquid level value measured by the liquid level measuring device 1 in this way is calculated by the microcomputer 4.
Processed to be displayed as a bar graph on the CRT.

The bar graph display of the remaining liquid amount is as follows:
For example, if the capacity of each container is the same, draw a replenishment display line A horizontally for the liquid volume of each container as shown in Figure 2, and if the top of each bar graph falls below the horizontal line, , the container may be configured to replenish the liquid, and if each container has a different capacity, a replenishment limit line for each bar graph corresponding to each container may be set for each container, and the liquid in each container may be refilled. It can also be configured to call attention by changing the display color of the bar graph to a warning color such as red when the remaining liquid amount falls below each replenishment limit line.

[Effects of the device] As explained above, this device is configured to display the remaining liquid amount in each container as a bar graph.
Workers can easily visually check the degree of decrease in the amount of liquid in each container at a glance. Blood samples and reagent replenishment management can be done very easily and accurately, and when the amount of liquid is insufficient, the bar graph display changes, so anyone can easily determine when to replenish the liquid. Therefore, this type of liquid replenishment management is greatly simplified.
