Multi-reagent colorimeter tube for portable colorimetric device

Abstract

The invention discloses a multi-reagent colorimeter tube for a portable colorimetric device. The multi-reagent colorimeter tube comprises a reaction cup (1) used for storing a first reagent and / or a to-be-detected sample, and a reagent bottle (2) used for storing at least one solid reagent, wherein openings are formed in the upper end of the reaction cup (1) and the lower end of the reagent bottle (2), and the upper end of the reaction cup (1) and the lower end of the reagent bottle (2) are in inserted connection with each other; a reagent bottle cover (6) is arranged on the upper part of the reagent bottle (2); a cavity (2.1) used for containing the solid reagents is formed in the reagent bottle (2); a feeding channel (2.2) is formed in the lower end of the cavity (2.1) and is communicated with the opening of the reaction cup (1); a reagent separation bar (3) through which the solid reagents are limited in the cavity (2.1) or drop into the reaction cup (1) by virtue of the feeding channel (2.2) is connected into the reagent bottle (2) in a sliding mode; and a through hole (9) through which the reagent separation bar (3) passes is formed in the reagent bottle cover (6).

Description

technical field [0001] The invention relates to the field of sample detection, in particular to a multi-reagent colorimetric tube used in a portable colorimetric device. Background technique [0002] At present, the colorimetric tube is used in the chemical analysis and detection of samples, and the photometric detection of the reacted colorimetric tube is carried out by the instrument to determine the chemical composition of the sample. The colorimetric tube is widely used in environmental protection detection (such as river water quality detection), food quality detection In the field of testing, medical testing or other industries, the portable colorimetric tube is small in size and can be used to carry it out to test samples on the spot, which is real-time and convenient. [0003] For example, in many medical tests, it is necessary to mix the sample to be measured with the first liquid, so as to remove the interfering components in the sample and start the first chemical...

AI Technical Summary

Problems solved by technology

[0006] 1) The amount and ratio of the first liquid and the second liquid used to react with the sample need to be strictly controlled, and the above method of mixing the first liquid and the second liquid by pushing the sealing plug makes it easy for the second liquid to remain in the The inner wall of the second mixing container or the sealing plug will lead to inaccurate dosage of the second liquid participating in the reaction, thereby affecting the reaction between the first liquid and the second liquid, and ultimately leading to low accuracy of photometric detection, which is easy to detect in medical testing. misdiagnosis or false positive;

[0007] 2) Existing colorimetric tubes are only suitable for the mixing of two liquid reagents
