Problems solved by technology

Because phosphate is easy to crystallize, the crystal sticks to the liquid injection pipe, the liquid injection pipe reciprocates, and the sealing ring is worn out for a long time, resulting in phosphate leakage, causing corrosion of related parts, and resulting in motion stagnation

Abstract

The invention relates to a double-cavity diluting apparatus. The double-cavity diluting apparatus comprises a washing cavity, a diluting container, a washing pipe and a liquid injection cavity; the top side wall and the bottom side wall of the washing cavity are respectively provided with a liquid inlet and a liquid outlet; the diluting container is rotatably arranged in the washing cavity, the diluting container is symmetrically provided with two diluting cavities with one end being opened, and the diluting container can be driven by a driving device to rotate; the liquid injection cavity isarranged below the washing cavity, and the liquid injection cavity is connected with a liquid injection pipe; and the washing pipe penetrates through the liquid injection cavity and a communication hole between the liquid injection cavity and the washing cavity to enter the washing cavity and is driven by the driving device to move up and down. By adopting the double-cavity diluting apparatus, phosphate in the washing cavity is prevented from flowing into the liquid injection cavity, the washing pipe is flushed, the part, contacting the phosphate, of the washing pipe is always immersed in thepurified water and does not contact a friction sealing ring, and the crystallization of the liquid injection pipe is effectively prevented from damaging a sealing member.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a double-chamber sample dilution device in a chemiluminescence immunoassay analyzer. Background technique [0002] In chemiluminescent immunoassay, some items such as CA15-3, β2-MG, etc., need to be diluted before the sample is added to the cuvette because the concentration of the sample marker is too high. Dilution is divided into three steps: 1. First, the sampling needle absorbs a certain amount of diluent and injects it into the container of the double-chamber dilution device; 2. The sampling needle absorbs a certain amount of sample and injects it into the container that has been filled with diluent in the previous step. Middle; 3. The sampling needle draws the mixed and diluted sample, injects it into the cuvette, and starts the detection and measurement. Before each dilution, the container containing the solution needs to be cleaned first to prevent the sample from being co...
