Convenient-operation smear sampling reagent bottle

Abstract

The invention relates to a biological detection sampling tool, in particular to a convenient-operation smear sampling reagent bottle, the reagent bottle comprises a bottle body, a bottle cap and a sampling core rod attached to the inner side of the bottle cap. An extension rod is connected to the outer side of the bottle cap, and the extension rod is connected to the bottle cap through a cap connector. The bottom of the bottle body is provided with a liquid drop head and a drip cover cooperated with the liquid drop head. the liquid drop head and the bottle body are integrally formed, and the bottle body communicates with the outside through the liquid drop head, and the sampling core rod is fixed on the bottle cap through a fixing ring. the inner side of the bottle cap is provided with a core rod limiting sleeve matched with the sampling core rod, and the length of the core rod limiting sleeve is greater than the length of the bottle cap. The liquid drop head is designed at the bottomof the bottle body to facilitate the dripping operation, and at the same time, the structure of the extension rod is designed on the bottle cap, the length of the sampling core rod can be lengthened,therefore, the bottle is convenient to sample anywhere, and has wide application range, and the core rod limiting sleeve is used to accurately control the smear sampling force of the sampling core rodto ensure the sampling precision.

Description

technical field [0001] The invention relates to a sampling tool for biological detection, in particular to an easy-to-operate smear sampling reagent bottle. Background technique [0002] The smear sampling reagent bottle generally adopts the smear method to sample the bacteria, and then pours or drops the obtained sample into the medium for identification after dilution; the smear sampling reagent bottle generally includes a bottle body, a bottle cap and a sampling mandrel. At present, In conventional smear sampling reagent bottles, the bottle cap is generally opened, and then the internal sample diluent is poured into the designated detection bottle for detection; this structure is not only troublesome to operate, but also easy to contaminate the sample; therefore, an improved Smear the sampling reagent bottle, design a drip head on the bottle cap, and drop the sample dilution liquid into the designated detection bottle for testing by means of dripping; although this struct...

[0002] The smear sampling reagent bottle generally adopts the smear method to sample the bacteria, and then pours or drops the obtained sample into the medium for identification after dilution; the smear sampling reagent bottle generally includes a bottle body, a bottle cap and a sampling mandrel. At present, In conventional smear sampling reagent bottles, the bottle cap is generally opened, and then the internal sample diluent is poured into the designated detection bottle for detection; this structure is not only troublesome to operate, but also easy to contaminate the sample; therefore, an improved Smear the sampling reagent bottle, design a drip head on the bottle cap, and drop the sample dilution liquid into the designated detection bottle for testing by means of dripping; although this structure can prevent sample contamination, it needs to invert the dripping, The operation is not very convenient, and the length of the sampling mandrel is fixed, so it is difficult to sample corners. The sampling environment and sampling distance are limited to a certain extent. Accuracy is not guaranteed
