Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Paraquat detection reagent tubes, including a plastic suction tube 1, a colorless capillary 2 with both ends fused and filled with sodium bicarbonate is arranged in the plastic suction tube; The brown capillary 3 of sodium dithionite, the plastic pipette cap 4 movably connected with the plastic pipette. See figure 1 .

[0016] An annular groove 5 may also be provided on the plastic pipette (1), so that the space in the plastic pipette is divided into two parts through the annular groove 5, a part of the plastic pipette is provided with a capillary, and a part is not provided with a capillary. See figure 2 .

[0017] Sodium bicarbonate and sodium dithionite are of the same quality, and both sodium bicarbonate and sodium dithionite are 55±2mg.

[0018] The colorless capillary with both ends melted and filled with sodium bicarbonate 2 is prepared by filling s...

Abstract

The invention discloses a paraquat detection reagent tube. The reagent tube comprises a plastic liquid sucking tube (1); a colorless capillary tube (2) of which the two ends are sealed in a melting manner and the interior is filled with sodium bicarbonate, and a brown capillary tube (3) of which the two ends are sealed in a melting manner and the interior is filled with sodium hydrosulfite are arranged in the plastic liquid sucking tube; the plastic liquid sucking tube is movably connected with a plastic liquid sucking tube cap (4). The reagent tube is simple to operate, and long in available period; a reaction reagent is free from failure in one year; the reagent tube is high in sensitivity, can be semiquantitative when in colorimetric combination with a colorimetric board, and be quantitative accurately when combining with an ultraviolet light splitting luminosity instrument, and can be applied to a noncausal suspected paraquat poisoning patient to achieve the goal of clarifying a diagnosis at the earliest.

Description

technical field [0001] The invention relates to a paraquat detection reagent tube. Background technique [0002] Paraquat (fparaquat.PQ) is also known as paraquat and quatquat. The chemical name of its active ingredient is 1,1'-dimethyl-4,4'-bipyridine cationic salt. It is one of the most widely used herbicides in the world. Although paraquat is a moderately toxic pesticide, it is highly toxic to humans and animals. As there is no effective specific antidote, the mortality rate of accidental or deliberate oral administration of paraquat can reach 60.8%-87.8%. Therefore, no matter whether the cause of acute poisoning is clear or not, it is one of the key factors for the successful rescue of paraquat poisoning to determine whether it is paraquat poisoning as soon as possible during the emergency department and first aid process. [0003] In order to detect paraquat in body fluids, chemical reagents or kits are currently used for detection. However, during application, it was...
