Problems solved by technology

However, it is often very difficult to ensure the quality of samples and the accurate results of assays in this process.
In addition, due to the delay in time, the accuracy and reliability of the sample test results will be reduced
However, it is still difficult to obtain the test results directly on the spot, or to pre-process the samples in time after the samples are collected, and then send them to the laboratory for further test analysis.

Embodiment 1

[0023] Embodiment 1 of the present invention: microorganism cultivation

[0024] Such as figure 2 , the reservoir (1) is made of soft transparent rubber, the reaction tube (2), the breakable valve (3), the thin tube (4) is made of plastic, the tail of the reaction tube (2) is sealed, the thin tube (4) A microbial culture swab is placed at the end of the tube. First remove the liquid storage bag (1), take out the thin tube (4), collect the microbial culture sample with a swab at the end of the thin tube (4), put the microbial culture reagent solution into the liquid storage bag (1), and then reduce it. When starting the experiment, break the valve needle (5) of the breakable valve (3) from the connection with the valve body (6) by hand, make the thin tube (4) communicate with the liquid storage bag (1), and then squeeze the liquid storage The capsule (1) makes the microbial culture reagent solution reach the microbiological culture swab at the tail end of the thin tube (4) t...

Embodiment 2

[0025] Embodiment 2: the preparation of diluent

[0026] Such as image 3 , use the inoculation loop at the end of the thin tube (4) to accurately sample, then break off the valve needle (5), so that the reaction reagent in the liquid storage bag (1) flows to the inoculation loop to mix with the sample, and an accurate diluent can be obtained. And it can be dripped into the container through the small mouth at the tail end of the reaction tube (2).

Embodiment 3

[0027] Embodiment 3: the processing of solid sample

[0028] Such as Figure 4 , use the spiral sampling cone at the end of the thin tube (4) to take a solid sample (such as feces), and then pass through the compression hole (7) in the reaction tube to make the solid sample on the spiral sampling cone reach the required amount, and then break the valve needle (5) Make the reaction reagent in the liquid storage bag (1) flow to the spiral sampling cone to react with the solid sample to obtain the desired result.

Abstract

The sample collecting and testing device consists of liquid storing bag, reaction tube, destructive valve, and fine tube. The liquid storing bag is in front of the reaction tube; the destructive valve comprising valve needle and valve body is set inside the liquid storing bag; and the fine tube has front end inserted between the valve needle and the valve body. The present invention has simple structure, convenient use, low cost and other advantages, and may be used in completing sample collection, processing, reaction, obtaining result and other steps in biochemical enzyme activity analysis, microbe culture, urine sample testing, etc.

Description

Technical field: [0001] The invention relates to a chemical device, in particular to a chemical analysis device. technical background: [0002] Chemical analysis and testing devices are commonly used in medicine. The current practice in the medical field is to collect samples clinically and then send them to the laboratory for further laboratory analysis. However, it is often very difficult to ensure the quality of the samples and the accurate results of the tests during this process. In addition, the accuracy and reliability of the sample test results will be reduced due to the time delay. However, it is still difficult to obtain the test results directly on the spot, or to pre-process the samples in time after the samples are collected, and then send them to the laboratory for further test analysis. Invention content: [0003] The object of the present invention is to provide a chemical analysis and test device with simple structure, which can process samples in time,...
