A sample dilution device with reusable dilution positions

Abstract

The invention discloses a sample dilution device with reusable dilution stations. The sample dilution device comprises a purge chamber, a dilution chamber, a dilution chamber rotation driving part, a cleaning head part and a cleaning head driving part. The purge chamber comprises a purge cavity, the top of which is provided with a liquid feed inlet and the bottom of which is provided with a liquid outlet. The dilution chamber comprises two symmetrically-arranged dilution cavities which have openings facing towards two ends of the dilution chamber. The dilution chamber is rotatably installed inside the purge chamber and can be driven by the dilution chamber rotation driving part to rotate with the two dilution cavities' openings alternately facing upwards. The cleaning head part comprises a liquid inlet tube and a cleaning head. The cleaning head is provided with a liquid outlet hole communicated with the liquid inlet tube. The cleaning head is mounted below the dilution chamber. The cleaning head driving part is connected to the cleaning head part, and the cleaning head can be driven by the cleaning head driving part to move up and down so as to enter or exit from the dilution cavity. According to the invention, dilution stations can be cleaned after dilution. Thus, the same dilution station can be repeatedly used for dilution work.

Description

technical field

[0001] The present invention relates to the technical field of medical devices, in particular to a sample dilution device with reusable dilution positions. Background technique

[0002] Chemiluminescent equipment needs to dilute the sample when performing detection. At present, most equipment dilutes the sample and diluent into a cup position of the reaction cup. Since the cup position of the reaction cup cannot be cleaned, each dilution All need to occupy a cup position, which greatly reduces the utilization rate of the cuvette. Contents of the invention

[0003] The technical problem to be solved by the present invention is: by setting multiple dilution positions, the dilution positions occupied by the non-current dilution process are cleaned during the dilution process, so that the same dilution position can be used repeatedly for dilution work, and the efficiency of the dilution process is improved.

[0004] The technical solution adopted by the presen...
