Liquid sample collecting bottle

Abstract

The invention provides a liquid sample collecting bottle which comprises a bottle body, the bottle body comprises an inner wall and an outer wall, the inner wall comprises a cylinder part, and the cylinder part of the inner wall of the bottle body is provided with a guide rail which inclines from top to bottom and spirally descends. Compared with the prior art, the liquid sample extrusion rate is higher, so that the minimum amount of the liquid sample required by detection is more easily met, and the detection success rate and the accuracy of a detection result are further improved. The kit can be used for detecting new coronal pneumonia.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and further belongs to the field of medical testing, in particular to a liquid sample collection bottle. Background technique [0002] There are a variety of clinical lateral flow immunoassay devices that can be used to detect the presence of analytes in samples, such as hormones, sugars, adulterants, drugs of abuse (including injecting or smoking drugs), etc. Usually, a liquid sample is collected and added to a lateral flow immunoassay device to detect a certain or certain components in the liquid sample. [0003] Wherein, the liquid sample can be any volume of liquid for testing, inspection or research. The liquid sample can come from any liquid, such as body fluid, such as saliva or blood or urine or other liquids to be tested, such as water samples from pollution sources, liquid samples from beverages, etc. [0004] Liquid samples are typically collected and absorbed using a sam...

Problems solved by technology

The problem with the existing collecting bottles and sampling rods is that the liquid sample on the collecting element of the sampling rod cannot be fully squeezed out, that is, after extrusion, there are still more liquid samples remaining on the collecting element, so that only There are fewer liquid samples for subsequent detection, so it is easy to cause insufficient liquid sample volume for detection, resulting in test failure or inaccurate test results (especially when the liquid sample is saliva, generally, people or The amount of saliva that animals can release in a short period of time is very limited, which can easily lead to insufficient liquid sample volume)

In addition, when there is a buffer in the collection bottle, the collection element will also absorb and take away part of the buffer or the mixture of the liquid sample and the buffer, thus affecting the accuracy of the test results
