OG exemplary drawing
 
1. A smear staining machine, comprising:
a sample pipeline, configured to draw a test sample;
a sample driver, configured to drive the sample pipeline to draw or discharge the test sample;
a detector, configured on the sample pipeline and configured to detect a viscosity characteristic of the test sample flowing through the pipeline under a preset condition, wherein the detector comprises a pressure sensor, and the viscosity characteristic is a pressure data of the test sample when the test sample flows through the pipeline;
a smearing mechanism, configured to drop the test sample on a slide and smearing the test sample as a film according to a smearing parameter; and
a processor, electrically connected with the sample driver, the smearing mechanism and the detector respectively, wherein the processor is configured to control the sample driver to drive a drawing action or a discharging action of the sample pipeline, receive the pressure data output from the pressure sensor and determine a smearing parameter according to the pressure data, and control the smearing mechanism to smear the test sample according to the smearing parameter.
