<p>A device for measuring and proportioning fluids more finely and accurately in medical, veterinary and laboratory syringes having plungers. The measuring system of the device is based on a measurement mode using a vernier and a scale or graduations, and thus includes a standard scale (1) attached to or provided on the syringe barrel (3), as well as a scale (2) known as a 'vernier' for indicating accuracy. The latter scale (2) is attached to or provided on the syringe plunger (4) and may be used to indicate, check and measure fluid volume unit fractions between two divisions on scale (1), and between the tip of the plunger and the end of the syringe barrel.</p> |
