Method for analysing a spray generated by a device for dispensing fluid pharmaceutical product

A device for analyzing a spray generated by a spray device for spraying pharmaceutical fluid, the device being characterized in that it comprises:

• a spray head (1) of a spray device for spraying pharmaceutical fluid, said spray head (1) including a spray orifice (2);
• means (24) for causing a test fluid to pass through said spray head (1) towards said spray orifice (2), said test fluid being air at a temperature that is different from ambient temperature;
• a strioscopic setup (20) for displaying, by strioscopy, the flow (5) of test fluid leaving said spray orifice (2);
• and
• analyzer means (30) for analyzing said display of the test-fluid flow (5) so as to determine whether or not the test-fluid spray coming from said spray head (1) complies with predetermined specifications.
