Problems solved by technology

[0004] Since the components of these reagents are different from each other, due to errors in the reagent container replacement operation performed by the user, different reagents may come into contact with the suction nozzle, reagent splashes during the replacement operation, etc., resulting in contamination between the reagents, and accurate measurement results cannot be obtained. Reagents that are consumables become unusable, and the reagent flow path of the device needs to be cleaned again.

Embodiment 1

[0054] exist Figure 4 A first configuration example of the reagent container installation unit 502 is shown in the middle. The drawing shows a cross-sectional view (schematic diagram) of a state in which the suction nozzle 6 of the reagent container installation part 502 is inserted into the reagent container 101 . In the reagent container installation part 502 , the reagent container stand 204 is installed on the substrate 205 . The reagent container 101 is placed on the substrate 205 and combined with a guide rail 501 (not shown), so that the reagent container installation part 502 can enter and exit the cabinet of the device. In addition, the suction nozzle 6 can be coupled to the handle 202 and the nozzle support part 203 that can be raised and lowered from the reagent container stand 204 . In addition, a power supply unit 303 is connected to the reagent container installation part 502, and supplies power to the lock release mechanism 302, the RFID indexer 103, and the ...

Embodiment 2

[0072] exist Figure 8 A second configuration example of the reagent container installation unit 502 is shown in the middle. The main difference between the second configuration example and the first configuration example is that by combining the two suction nozzles 6-1, 2 on the nozzle support part 203 and lifting the handle 202 by the user, the two suction nozzles 6-1, 2 are simultaneously lifted. aspect. Figure 8 omitted in Figure 4 The illustrated container detector 104 and RFID indexer 103 are arranged corresponding to the reagent containers 101-1, 2, respectively. The reagent container replacement procedure is also compatible with Figure 7A The content shown in , B is the same, the user replaces one or more reagent containers, and when all the reagent container RFID information is normal, the nozzle holder 203 is unlocked by the lock release mechanism 302, and the nozzles 6-1, 2 are sucked. They move to predetermined suction positions in the reagent containers 101...

Embodiment 3

[0075] Such as Figure 8 The configuration in which a plurality of reagent containers are arranged side by side on the reagent container installation part 502 can make the reagent container installation part compact, and as described in the second embodiment, the efficiency of replacement work can be improved. Such as figure 1 As shown, in the case of the electrolyte analysis device, since three kinds of reagents of internal standard solution, diluent and comparison electrode solution are used, the configuration of the reagent container installation part 502 on which these three reagent containers are placed is considered as Example 3. Since the reagent container is replaced manually, the reagent splashes from the suction nozzle and the liquid overflows from the suction port of the reagent container during the replacement operation, so that the risk of product generation cannot be zeroed out. In particular, if a plurality of reagent containers are placed close to each other, ...

Abstract

The objective of the present invention is to provide an electrolyte analyzing device which prevents contamination resulting from a different reagent coming into liquid contact with a suction nozzle during a reagent exchange operation carried out by a user. To this end, the electrolyte analyzing device is provided with a reagent vessel placement unit 502 on which a diluent bottle 101-1 accommodating a diluent, an internal standard solution bottle 101-2 accommodating an internal standard solution, and a reference electrode solution bottle 101-3 accommodating a reference electrode solution, are placed, wherein the reagent vessel placement unit includes a separating wall between the diluent bottle and the internal standard solution bottle on the one hand and the reference electrode solution bottle on the other hand when the diluent bottle, the internal standard solution bottle, and the reference electrode solution bottle are placed thereon.

Description

technical field [0001] The present invention relates to an electrolyte analysis device. Background technique [0002] The electrolyte analysis device is a device for measuring the concentration of a specific electrolyte contained in an electrolyte solution such as blood or urine of the human body, and the concentration measurement is performed using an ion selective electrode. As a general measurement method, directly measure serum as an electrolyte solution, or supply a sample solution diluted with a diluent to an ion-selective electrode to measure and compare the inter-liquid potential of the electrode solution, and then (or before the above-mentioned measurement) to the ion-selective electrode The ion-selective electrode supplies the standard solution, similarly measures and compares the liquid potential of the electrode liquid, and calculates the electrolyte concentration of the sample solution from the two liquid potential levels. [0003] In this manner, in the flow-t...
