Urinalysis instrument

The invention discloses a urinalysis instrument. The urinalysis instrument comprises a pump, a water inlet pipeline, a sampling pipeline, a detection device and a control device, wherein the detection device comprises a flow channel plate, an air path pipeline, a water inlet pipeline and a sampling pipeline which are respectively operably connected to an inlet of the pump, a flow channel of the flow channel plate is operably connected to an outlet of the pump, the control device can control the pump to continuously suck out air in the flow channel plate, so the interior of the flow channel plate is in a vacuum state, and then a valve element is opened; a reagent in the kit flows into a flow channel in the flow channel plate through the valve body, and the pump drives air to enter the flow channel plate to drive the reagent to flow into the test pit. After the reagent flows into the test pit, the pump drives the urine to flow into the test pit of the flow channel plate from the sampling pipeline or a sample co
