Pipetting workstation

Abstract

The invention provides a pipetting workstation, which comprises a box body, a reagent arm mechanism used for automatically transferring a reagent into a mixing container, and a pipetting mechanism used for automatically transferring the reagent into the mixing container, wherein a reagent container, a sample container and a mixing container are placed in the box body; the sample arm mechanism is used for automatically transferring a sample into the mixing container; the reagent needle cleaning mechanism is used for cleaning the outer wall of the reagent needle; the sample needle cleaning mechanism is used for cleaning the outer wall of the sample needle; the liquid path mechanism is respectively communicated with the inner cavities of the reagent needle and the sample needle to clean the inner walls of the reagent needle and the sample needle; the liquid path mechanism is also used for providing outer wall cleaning liquid for the reagent needle cleaning mechanism and the sample needle cleaning mechanism; and a control screen is also arranged on the box body and is used for operating the corresponding movement mechanism. The invention provides a pipetting workstation, which has the functions of automatic cleaning, liquid suction and liquid spitting, realizes automatic transfer of reagents and samples into a mixing container, does not need manual operation, reduces the labor intensity, and improves the pipetting efficiency.

Description

technical field [0001] The invention relates to the technical field of medical testing equipment, in particular to a liquid transfer workstation. Background technique [0002] In biochemistry and other experiments, it is often necessary to transfer liquid medicines. Traditionally, simple pipetting devices such as glue tip droppers are used. When a large number of experimental samples are required, pipette guns are also used. [0003] The existing pipetting work is mostly manual operation, that is, manually pressing the pipetting pressure rod, the pipetting pressing rod pushes the tip to suck the reagent, mixes the reagent and the sample in the designated headspace bottle, and then caps the bottle. The cover is then sent for analytical testing. The pipetting workstation is a precision instrument. It must maintain the correct posture when using it, and the grip strength needs to be controlled during use. Moreover, the number of samples to be tested is large, and the operator ...

Problems solved by technology

The liquid pipetting workstation is a precision instrument, and the correct posture must be maintained when using it, and the strength of the grip needs to be controlled during use. Moreover, due to the large number of samples to be inspected and the operator is not unique, the error is increased. Probability, low work efficiency; and the manual pipetting method is also prone to pipetting errors, resulting in inaccurate test results
