Sealing reagent supply system

Abstract

The invention discloses a reagent supply system and provides a sealing reagent supply system which is simple in structure, high in capacity, good in sealing performance and long in service life. The sealing reagent supply system comprises a reagent storage bag (1) and a reagent supply box (2), wherein the reagent storage bag (1) is communicated with the reagent supply box (2) through a liquid transport pipe (3); a reagent accommodating pool is formed in the reagent supply box (2); a floating body adaptive to a pipe orifice of the liquid transport pipe (3) is arranged in the reagent accommodating pool; and when enough reagents are accommodated in the reagent accommodating pool, the floating body floats on the reagents and blocks the pipe orifice of the liquid transport pipe (3), so that the liquid transport pipe (3) stops supplying liquid to the reagent accommodating pool. The sealing reagent supply system is applied to the field of the reagent supply system.

Description

technical field [0001] The present invention relates to sealed reagent supply systems. Background technique [0002] The biochemical analyzer is an instrument that uses the principle of photoelectric colorimetry to measure a specific chemical composition in body fluids. Due to its fast measurement speed, high accuracy, and small consumption of reagents, it has been used in hospitals at all levels, epidemic prevention stations, and family planning service stations. be widely used. At present, the reagents used in biochemical analyzers are generally stored in kits. If a small-capacity kit is used, it needs to be replaced frequently. Due to the cumbersome replacement steps, it will take a long time; if a large-capacity kit is used, due to the The consumption of reagents is small, and the reagents stored in the large-capacity kits are easy to deteriorate, causing waste and affecting the test results of the biochemical analyzer. [0003] At present, there is a Chinese paten...

Problems solved by technology

At present, the reagents used in biochemical analyzers are generally stored in kits. If a small-capacity kit is used, it needs to be replaced frequently. Due to the cumbersome replacement steps, it will take a long time; if a large-capacity kit is used, due to the The consumption of reagents is small, and the reagents stored in the large-capacity kits are easy to deteriorate, causing waste and affecting the test results of the biochemical analyzer

[0003] At present, there is a Chinese patent with a publication number of 2886571, which discloses a fully automatic biochemical analyzer kit. The box body is composed of three reagent bottles, large, medium and small. The inner bottom of the reagent bottle is a concave arc or conical bottom. When the reagent is about to be used up, the distribution area of ​​the reagent box is small and the liquid level of the reagent is high when the reagent is about to be used up. When it is very small, the reagent liquid level will be lower than the detection depth of the reagent probe, and the signal of reagent running out will appear, but this patent still does not solve the problem of frequent replacement of the kit or the easy deterioration of the reagent in the kit
