Delivery device and method for its operation
First Claim
1. A multi chamber syringe cartridge container, configured for use with a portable preparation delivery device, comprising a generally cylindrical barrel with a general symmetry axis and having a front end and a rear end, provided with an opening or a preparation for an opening at its front end;
- at least one displaceable piston inserted in the barrel between the front end and the rear end; and
a machine readable marking on the barrel,wherein the marking comprises at least two marking areas with different detectable absorbency or reflectance when irradiated with radiation in non-visible frequency ranges,wherein the piston has at least one surface part with detectable absorbency or reflectance when irradiated with radiation in non-visible frequency ranges and said piston surface part is exposed or exposable to the radiation through at least a part of the barrel, andwherein at least one of said marking areas and said piston surface part are located at the same position along the barrel symmetry axis.

Abstract
A system of marked medical containers comprises at least two containers having different properties in at least one respect, and at least one machine-readable marking on each of the containers, each marking being designed to allow discrimination between the difference in properties. Each marking allows discrimination between the difference by having at least one area with different absorbence or reflectance when irradiated with radiation in non-visible frequency ranges. A specific container comprises a syringe cartridge type container for use with a preparation delivery device.
