Abstract

The invention discloses a liquid-way system of a fully-automatic fecal occult blood analyzer, which is composed of an automatic sample adding module and a cleaning module, wherein the automatic sample adding module is used for adding samples and reagents; the cleaning module is used for cleaning sample needles, reagent needles and stirring rods; the automatic sample adding module is composed of asample injection pump, a sample needle, a reagent injection pump, a three-way solenoid valve, a reagent needle and a buffer solution bottle; and the cleaning module is composed of a cleaning injection pump, a three-way solenoid valve, a sample injection pump, a cleaning solution bucket, a cleaning pump, a two-way solenoid valve, a cleaning tank, a waste liquid pump and a waste liquid bucket. The invention has the beneficial effects that the injection rates of samples and reagents are controlled by the injection pumps, the quantitative accuracy is high, and the cleaning pump and the waste liquid pump are diaphragm pumps, thereby meeting the operating requirements and lowering the cost at the same time.

Description

technical field [0001] The invention relates to a fully automatic fecal occult blood analyzer, in particular to a liquid path system of the fully automatic fecal occult blood analyzer. Background technique [0002] In the automatic fecal occult blood analyzer, in order to realize the function of clinical testing, its liquid system should have the function of automatic sample addition, so as to realize the reaction between samples and reagents in the cuvette; at the same time, the liquid system should also have a cleaning function, which Including the cleaning of the inner and outer walls of the sample needle, the cleaning of the reagent needle and the cleaning of the stirring rod to minimize cross-contamination between tests. [0003] At present, there are many ways to realize these liquid circuit functions. For example, high-precision ceramic syringe pumps are used for automatic sample addition, but the cost is relatively high; swabs are used for cleaning sample needles and...
