Method of Tracking and Tracing Syringes in the Pharmaceutical Industry

A method of safely tracking and tracing a pharmaceutical container content during the life of the pharmaceutical container, comprising:

• (a) providing a cylindrical pharmaceutical container filled with a pharmaceutical content;
• (b) adding to the surface of the pharmaceutical container an identification code, wherein the identification code is made of a material that is not visible under ambient light, wherein the identification code contains encrypted information regarding temporal and physical properties of the pharmaceutical container and pharmaceutical fluid content of the pharmaceutical container;
• (c) detecting the identification code with an optical detection method at multiple stages during the life of the pharmaceutical container, wherein the identification code is only visible by using the optical detection method comprising:
• (i) a diffused single-edge backlighting method in which only up to one half of the pharmaceutical container is illuminated and changes in index of refraction according to changes of its light source angle of incidence are detected, or a (ii) a dark-field reflective method in which a collimated light source is used to illuminate the pharmaceutical container and light reflecting off the outer surface of the pharmaceutical container is detected according to changes of its light source angle of incidence;
• (d) decrypting from the detection the encrypted information of the identification code using a computer-implemented decrypting method;
• and
• (e) verifying the decrypted identification code at each stage of the multiple stages and outputting a safety and efficacy report pertaining to the pharmaceutical fluid content of the pharmaceutical container, wherein the comparing and outputting utilizes a computer-implemented method,
• wherein the method improves safety and efficacy of the pharmaceutical fluid content of the pharmaceutical container during the life of the pharmaceutical container and its fluid content.
