Abstract

The invention discloses an aspiration needle cleaning system. The aspiration needle cleaning system comprises a base, a lifting driving device, a permanent magnet and a magnet driving device, wherein the base is provided with a cleaning tank cavity with an upward opening, and a plurality of cleaning magnetic beads are arranged in the cleaning tank cavity. The lifting driving device is installed on the base, a needle tube fixing structure used for fixing an aspiration needle is arranged at the lifting end of the lifting driving device, and the needle tube fixing structure is located over the cleaning tank cavity. The permanent magnet can be magnetically attracted with the cleaning magnetic beads. The magnet driving device is used for driving the permanent magnet to move far and near relative to the cleaning tank cavity. Through starting of the magnet driving device and the lifting driving device, the cleaning magnetic beads get close to or away from the inner wall and the outer wall of the aspiration needle and move relatively in the vertical direction, the cleaning magnetic beads rub the inner wall and the outer wall of the aspiration needle, and then the erasing effect is achieved; with more activity times and more cleaning magnetic beads, the overall cleaning effect of the inner wall and the outer wall of the aspiration needle is achieved; and the problem that an existing aspiration needle is poor in cleaning effect can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of cleaning needle tubes, and more specifically, relates to a liquid suction needle cleaning system. Background technique [0002] At present, the cleaning mechanism of the traditional automatic immunoassay analyzer (or automatic fluorescent PCR) detection platform on the market is cumbersome in terms of cross-contamination, especially the cleaning of the suction needle after suction. It needs to be cleaned dozens of times, wasting a lot of time And cleaning fluid, due to errors in the accuracy of related components (cleaning pumps and liquid circuits), there is a large deviation in the test results (especially the detection of infectious items). [0003] The traditional cleaning mechanism basically uses the pressure of the pump to drive the cleaning liquid to clean the residue inside the aspirating needle. However, due to the structural characteristics of the aspirating needle and the distance from the pump...
