Quantitative sampling filling device and method for quantitative sampling filling using the same

Abstract

The invention discloses a quantitative sampling and filling device and a quantitative sampling and filling method using the same. The device includes: an outer tube, which includes a guiding tube defining a guiding cavity and a mixing tube defining a mixing cavity. The guide cavity is in communication with the mixed liquid cavity; an inner tube has a proximal end and a distal end, at least part of the inner tube is installed in the guide cavity, and the proximal end of the inner tube guides the guide cavity. The end of the cavity is blocked to isolate the guide cavity from the mixed liquid cavity; and a capillary pipette extends axially from the distal end to the proximal end inside the inner tube, and the The liquid mixing chamber communicates with the outside world through the capillary pipette. According to the present invention, only one set of devices can be used to complete the suction and pipetting of the sample, the mixing of the buffer solution and the sample liquid, and the quantitative titration and injection of the mixed solution after the mixing reaction.

Description

technical field [0001] The invention relates to the field of reagent titration detection, in particular to a quantitative sampling filling device and a quantitative sampling filling method using the same. Background technique [0002] In the traditional detection and analysis process, the sample is usually collected first, then the sample is injected into the reagent or buffer for reaction, and finally the reacted liquid sample is transferred to the detection device for detection. Collecting samples and adding reagents generally requires repeated use of multiple devices such as pipette guns, buffer plates or capillary pipettes. Generally, two or more types of pipetting devices are required to complete the detection process during detection, so that the entire The transfer and titration process has disadvantages such as cumbersome operation, easy pollution, and misoperation, and there are problems such as inconvenient portability and high environmental cleanliness requirement...

[0002] In the traditional detection and analysis process, the sample is usually collected first, then the sample is injected into the reagent or buffer for reaction, and finally the reacted liquid sample is transferred to the detection device for detection. Collecting samples and adding reagents generally requires repeated use of multiple devices such as pipette guns, buffer plates or capillary pipettes. Generally, two or more types of pipetting devices are required to complete the detection process during detection, so that the entire The transfer and titration process has disadvantages such as cumbersome operation, easy pollution, misoperation, etc., and there are problems such as inconvenient carrying and high environmental cleanliness in outdoor or special scenarios, and there are major design defects.
