Collector

Abstract

The invention relates to the technical field of biomedicine, and provides a collector. The collector comprises a pipe body, the pipe body is internally provided with a filter plate in the axial direction, and the filter plate divides an accommodating space of the pipe body into an initial sample storage area and a sample extraction area in the axial direction. The collector has the advantages thata swab attached with oral exfoliative cells is placed in the initial sample storage area, DNA in the cells is released by cracking components in a preservation solution, and the DNA is filtered through the filter plate to the sample extraction area, so that bending or position deviation of a sampling needle due to the contact between the sampling needle and the oral swab is avoided; on the otherhand, when the collected saliva contains thick sputum or food debris, the clogging of the sampling needle is prevented by filtering through the filter plate, there is no need to take out the swab or liquefy the sputum in the operation, the operation is convenient, and the time is saved.

Description

technical field [0001] The invention relates to the technical field of biomedicine, and more specifically relates to a collector. Background technique [0002] Human saliva is a complex mixture that contains not only oral exfoliated cells but also various proteins. Studies have found that various protein components in blood also exist in saliva, and saliva can reflect changes in the levels of various proteins in blood. Since the acquisition of oral exfoliated cells or saliva does not require trauma and is convenient to collect, it is widely used in various medical tests, such as gene sequencing tests. In addition, in the prior art, when collecting saliva, oral swabs can also be used to collect DNA samples of human oral mucosa exfoliated and renewed. For the convenience of carrying and storage, a collector is usually used to collect test samples. In the prior art, the collector includes a collection part and a tube body. Generally, the swab or saliva is collected into the tu...

Problems solved by technology

For the convenience of carrying and storage, a collector is usually used to collect test samples. In the prior art, the collector includes a collection part and a tube body. Generally, the swab or saliva is collected into the tube body through the collection part, and then the tube body is placed on the platform for testing. Re-extraction, in order to prevent the extraction equipment such as the pipette needle from being damaged, it is necessary to remove the stored swab from the tube before proceeding. The operation is more complicated, especially when operating a large number of collectors, which wastes time and reduces the extraction efficiency.
