Abstract

The invention relates to an automatic reagent dropping system of a urine analysis meter, belonging to the field of the urine analysis meter. The automatic reagent dropping system provided by the invention is of a double-probe structure and comprises a sampling mechanism, a dropping mechanism, a sampling cleaning mechanism and a dropping cleaning mechanism. The automatic reagent dropping system provided by the invention effectively enhances the speed of dropping and realizes the testing result of 480 parts every hour. In the automatic reagent dropping system provided by the invention, the sampling and dropping system drives a synchronous belt to make a motion by adopting a motor in a transmission mode, and the extraction and sampling of samples are carried out by utilizing an injection pump, an electromagnetic valve and a pipeline. In the automatic reagent dropping system provided by the invention, the accuracy of the sampling and the dropping is improved to the great extent; and the double probes are alternately operated in parallel, thereby greatly improving the work efficiency. The two paths of cleaning mechanisms avoids the cross contamination among the samples to the great extent and improves the accuracy of the test result.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a system for simultaneous and alternate operation of dual-probe sampling and sample dropping. Background technique [0002] Urine analyzer is an automatic instrument for determining certain chemical components in urine, and it is an important tool for automatic urine inspection in medical laboratories. Most of the previous urine analyzers used to manually soak the test strips and manually put the test strips into the machine for testing, which was extremely inconvenient. In the later stage, a full-automatic urine analyzer appeared in the market, and its sampling and dripping are all done automatically. The whole sampling and dripping action is completed by a probe. The action takes longer to complete. It is more troublesome to implement and less efficient. Contents of the invention [0003] The invention provides a reagent automatic sample dropping system for a urine...
