Liquid sample collection device and detection device

Abstract

The invention provides a liquid sample collecting device which comprises a liquid sample collecting bottle and a sampler, a guide rail which inclines from top to bottom and spirally descends is arranged on the inner wall of the liquid sample collecting bottle, and a guide groove is formed in the lower end of a rod part of the sampler. After the lower end of the rod part of the sampler is inserted into the liquid sample collecting bottle, the guide groove at the lower end of the rod part is matched with the guide rail on the inner wall of the bottle body to guide the lower end of the rod part of the sampler to spirally descend in the liquid sample collecting bottle, so that the liquid drawing part of the sampler is twisted and squeezed. 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 devices, and further belongs to the field of medical testing, in particular to a liquid sample collection device and a detection device. 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. Liquid samples can be derived from any liquid, such as body fluids such as saliva or blood or urine or other liquids to be tested, such as water samples from contaminated sources, liquid samples from beverages, etc. [0004] Liquid samples are typically collected ...

AI Technical Summary

Problems solved by technology

The problem with existing collection bottles and sampling sticks is that the liquid sample on the collection element of the sampling stick cannot be fully squeezed out, that is, after extrusion, there are still more liquid samples remaining on the collection element, so 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 buffer in the collection bottle, the collection element will also absorb and take away part of the buffer or the mixture of liquid sample and buffer, thus affecting the accuracy of the test results
