Abstract: A liquid dispensing pump (10) comprises: a first liquid storage cylinder (11), a second liquid storage cylinder (12), a first plunger (13) movably connected to the first liquid storage cylinder (11), a second plunger (14) movably connected to the second liquid storage cylinder (12), and a drive assembly (15) connected to the first plunger (13) and the second plunger (14). The first liquid storage cylinder (11) is provided with a first liquid entry and exit port (111). The second liquid storage cylinder (12) is provided with a second liquid entry and exit port (121). One end of the first plunger (13) is inserted into an internal cavity of the first liquid storage cylinder (11). One end of the second plunger (14) is inserted into an internal cavity of the second liquid storage cylinder (12). Further provided is a liquid dispensing device (100).

Abstract: A method and apparatus for automatic engagement with an analyzer, a computer device and a storage medium The method comprises: acquiring test information of a sample under test and state information of an analyzer, the state information indicating whether the analyzer is in an idle state or an operating state (102); if the analyzer is in an idle state, conveying the sample under test to the analyzer (104); and performing a test on the sample under test according to the test information (106). The method can acquire state information of an analyzer to enable a sample under test to be conveyed to the analyzer timely for performing a test thereon without requiring maintenance personnel to adjust the analyzer according to the state information of the analyzer, thereby reducing manual costs and increasing operation efficiency of the analyzer.

Abstract: A light avoidance structure (100) for detecting an optical signal, comprising: a base (10), a rotating body (20) pivotally connected to the base (10), and a cover plate (30) arranged facing toward the rotating body (20). The rotating body (20) is provided with a first light shielding member (21); the rotating body (20) is provided with at least one cup hole (22); the cup hole (22) is provided with a detection port (221); the cover plate (30) is provided with a second light shielding member (31); the second light shielding member (31) and the first light shielding member (21) match each other so as to form an annular structure used for shielding light, and a gap (311) is provided at the connection of the second light shielding member (31) and the first light shielding member (21); the detection port (221) is located at the outer side of the first light shielding member (21) and the second light shielding member (31); and the cover plate (30) is provided with at least one hole (32).

Abstract: A device for separating a reagent from a reactor includes a collecting means, provided with a liquid receiving port and a solid receiving port, a holding component disposed above the collecting means and used for placing the reactor, and a rotating mechanism for driving the holding component to rotate. The liquid receiving port and the solid receiving port are arranged at different positions in the circumferential direction of rotation of the holding component, when the holding component passes over the liquid receiving port, reagent in the reactor falls into the liquid receiving port, when the rotating mechanism continues rotating in the original direction until the holding component passes over the solid receiving port, the reactor falls into the solid receiving port from the holding component.
