The present invention relates to a method for controlling an automatic biochemical analyzer that automatically analyzes various components of multiple samples such as blood and urine, and particularly to a control method for a reagent dispenser in an automatic biochemical analyzer for multiple items. It is about the method. In recent years, automatic analyzers have been introduced into hospital laboratories or testing centers, greatly contributing to speeding up biochemical testing and improving accuracy. Particularly recently, multi-item automatic analyzers are being used that can analyze many different types, for example, 30 items, with a single device. In such a multi-item automatic analyzer,
Generally, when dispensing a test solution into a reaction container, a special dispenser is used to dispense one type of test solution. In this case, there is a one-to-one correspondence between the dispenser and the test solution, so there is no contamination between the sample solutions in the dispenser, but when analyzing multiple items, the number of dispensers required is equal to the number of test solutions. Therefore, there is a drawback that the device becomes large and the cost increases. By improving this, parts that come into contact with the test liquid (e.g. probes that make up the dispensing mechanism)
There is a device that prepares only a few samples of test solution and then switches that section to dispense the sample solution into the reaction container.
Because it switches in the middle of the flow path, liquid leaks are likely to occur.
Dispensing accuracy deteriorates. In addition, there are 20 to 30 types of test solutions.
When the number of species increases, the structure of the device becomes very complicated. Furthermore, there is a device with a simpler structure that dispenses all reagents with a single dispenser, but this requires a special method for cleaning to reduce contamination between reagents, and also requires a cleaning solution. It has the disadvantage of requiring a large amount of The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art,
By reducing the number of dispensers to less than the number of reagents and making the device more compact and using a device with a simple structure with good dispensing accuracy, we can eliminate the effects of contamination between reagents in a simple manner without requiring a large amount of cleaning solution. The aim is to provide a method by which the device can be controlled so as to reduce The present invention includes a reagent dispenser for dispensing a reagent into a reaction container containing a sample such as blood, and a cleaning section for cleaning the reagent dispenser, and the number of reagent dispensers is determined by the type of the reagent. When controlling an automatic biochemistry analyzer that automatically performs component analysis of multiple items in a liquid using a common reagent dispenser, it is important to consider the relationship between items that are susceptible to contamination between reagents. A plurality of items are set or stored in the device in advance, a plurality of items to be analyzed are inputted into the device, the inputted plurality of items are stored in the device, and based on the stored plurality of items and the set or stored relationship, The present invention is characterized in that the reagent liquid dispenser is controlled so as to perform analysis of a plurality of items in an order that reduces the influence of contamination between reagent liquids to a negligible extent. The present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram showing a partial configuration of an example of an automatic biochemical analyzer suitable for carrying out the control method according to the present invention. 1 is a reaction lane, and a large number of reaction tubes 2 containing samples to be analyzed are intermittently sent in the direction of the arrow. The reaction tube 2 advances to a reagent dispensing position N, where a predetermined amount of reagent is dispensed by the reagent dispensing nozzle 3. For this purpose, the reagent dispensing nozzle 3 is connected to the reagent tank 4. The test liquid tank 4 contains test liquids (A) to (L) for predetermined items so that analysis of a plurality of items can be performed. This test liquid tank 4 is rotated in both directions as shown by the arrow and is placed at a predetermined position M.
The desired reagent solution can be quickly determined. After sucking the test solution from the test solution tank 4 through the test solution dispensing nozzle 3 and dispensing this test solution into the reaction tube 2 at a predetermined position N, the reaction tube 2 moves further forward, during which time a predetermined reaction takes place. move on. When the reaction tube 2 reaches a photometric position (not shown), photometry is performed. On the other hand, the reagent dispensing nozzle 3 that dispenses the reagent into the reaction tube 2 is cleaned by the washer 5. Next, the cleaned reagent dispensing nozzle 3 sucks the reagent at a predetermined position M from the reagent tank 4 and dispenses it into the reaction tube 2 at a predetermined position N. That is, in this embodiment, a plurality of test solutions (12 types in this case) can be dispensed using one dispensing nozzle 3. In this case, since the reaction tubes 2 on the reaction lane 1 dispense multiple test solutions using the same dispensing nozzle 3 according to each analysis item, mutual contamination between test solutions may affect the analysis. be. The degree to which this contamination affects analysis differs depending on the type of test solution, and there are some items in which some degree of contamination between test solutions is not a problem. On the other hand, there are items that are greatly affected by contamination between test solutions. Examples include (1) transaminases GOT and GPT (Karmen method, etc.) and dehydrogenases LDH and α-HBD (2) items that use phosphate buffers (BUN, GLU, etc.).
etc.), inorganic phosphorus (3), reducing agents contained in iron measurement test solutions, and color-forming items using 4-aminoantipyrine (enzymatic methods such as TG, GLU, T-CHOL, etc.). Conventionally, in order to reduce the effects of contamination between test solutions, special methods were used for cleaning or large amounts of cleaning fluid were used. This method does not take into account the degree of influence of contamination between test solutions, and is wasteful in that a large amount of cleaning solution is used even between items that are less affected by contamination. In order to eliminate such waste, the order of analysis items may be specified so that items that are significantly affected by contamination between test solutions are not consecutive. Focusing on this point, the present invention attempts to use a computer to designate the order of analysis items and control the operation of the dispenser so as to reduce the influence of contamination between reagents. FIG. 2 is a diagram showing the configuration of an example of a control system of a reagent dispenser suitable for carrying out the control method according to the present invention. Analysis item information of the specimen to be measured obtained by photometry of the reaction tube 2 described above is supplied to the central information processing unit 7 from the input device 6 (for example, a keyboard, a floppy disk, etc.). The central information processing unit 7 stores this information in the memory 8. On the other hand, among the analysis items, combinations of items that are significantly affected by contamination between test solutions are stored in the memory 8 in advance. The central information processing unit 7 also connects the reagent tank 10, the dispenser section 12, and the cleaning section 14 via each interface 9, 11, and 13 according to a preset program.
control the behavior of In this case, the order of the items to be analyzed for each specimen is not fixed, but the best combination is determined so that the items that are significantly affected by the contamination between the test solutions are not consecutive, and control is performed based on the results. To give an example, assume that the relationships between items (A) to (L) are as shown in the following table. An x mark indicates that the influence of mixing the horizontal item with the test liquid of the horizontal item is greater than that of the vertical item. In other words, if I is measured after measuring E, E will be mixed into I and have a large effect.

Assume that the analysis items for samples No. 1 to No. 5 are specified as follows. No. 1 ABCEFH No. 2 ABDJ No. 3 ABCDEHJK No. 4 EFHIL No. 5 ABCDEF In this case, from the table above, it is recommended to rearrange the items in the following order so that the influence of contamination between test solutions does not increase. can. No. 1 ABECFH No. 2 ABJD No. 3 EABHCDJK No. 4 EFHIL No. 5 ABECDF In the worst case, there may be cases in which only items with large contamination effects occur in succession (in reality, such cases occur frequently). However, in this case: 1. Even if it is not included in the analysis item specification, items that have a small contamination effect will be compulsorily included. 2 Stop dispensing the reagent for one cycle and perform only the cleaning operation. 3. Perform calibration (for example, test solution blank measurement) using a test solution that is less susceptible to contamination. The effects of contamination between test solutions can be avoided by methods such as As described above, according to the present invention, since an apparatus is used in which the number of dispensers is smaller than the number of reagents for analysis items, the apparatus can be downsized, and the dispensing accuracy can be improved without the need for a special mechanism. It can be made into a good structure. Furthermore, since the computer is used to specify the order of analysis items and control the dispenser so as to reduce the influence of contamination between reagent solutions, the influence of contamination between reagent solutions can be efficiently avoided. In addition, the amount of cleaning liquid used to clean the dispenser can be the amount required between items that is less affected by inter-reagent contamination, so a large amount of cleaning liquid is not required, and a device with a small tank capacity for storing cleaning liquid can be used. Can be done. The present invention is not limited to the above-mentioned examples, and can be modified and modified in many ways. Although one dispensing nozzle was used in the above example, it is also possible to control the use of multiple dispensing nozzles in consideration of mutual contamination between test solutions. It is possible to control the amount of liquid, or to use a specific dispensing nozzle for a specific reagent solution.
