Problems solved by technology

[0004] In addition, the existing methods often use cotton swabs or small digging spoons to directly collect a certain amount of samples visually, then add an appropriate amount of normal saline or PBS, and centrifuge to take the supernatant or sediment for downstream experiments. It is difficult to achieve standardized quantitative sampling and one-step samples pre-processing

Abstract

The invention relates to the technical field of biology, in particular to a sample collection and homogenization pretreatment device which comprises a sample homogenization unit and a liquid storage unit, and a liquid storage inner cavity comprises a first cavity located in the sample homogenization unit and a second cavity located in the liquid storage unit. A liquid seal unit for dividing the first cavity and the second cavity is arranged between the first cavity and the second cavity, and a quantitative sampling unit is arranged in the first cavity; a puncture unit for puncturing the liquid sealing unit is arranged in the second cavity, and the pretreatment device also comprises a driving part for driving the puncture unit to reciprocate; a liquid outlet communicated with the first cavity is formed in one end, far away from the liquid storage unit, of the sample homogenizing unit, and a filtering unit is arranged between the first cavity and the liquid outlet. By using the device, a homogenate sample can be accurately and quantitatively obtained, the operation is extremely simple, the use is convenient, and the standardization degree of sampling before sample detection, transportation and treatment before homogenate can be furthest improved.

Description

technical field [0001] The invention relates to the technical field of biology, in particular to a sample collection and homogenization pretreatment device. Background technique [0002] Molecular biology-related technologies have been widely used for gene screening or diagnosis because of their strong detection specificity, high sensitivity, and short window period, especially in clinical, disease prevention and control, food safety testing, and research. In various scenarios such as export quarantine inspection, it shows a rapid development of 20% every year. Genetic screening or diagnostic technologies mainly include molecular hybridization, fluorescent qualitative / quantitative, next-generation sequencing, and next-generation sequencing. These technologies mainly include sample collection and pretreatment, nucleic acid extraction and detection, and other operations. The rapid growth of sample testing items has brought heavy psychological pressure to clinical laboratory p...
