Abstract
This invention relates to a method of identifying an accurate dosage of medicine in a dosage chamber of a syringe including the steps of providing an accurate dosage of a detailed single dosage medicine for insertion into a dosage chamber of a syringe; identifying the accurate dosage of medicine in the dosage chamber by retaining a notifier of the accurate dosage; securing the notifier with the syringe wherein the accurate dosage of medicine in a dosage chamber of a syringe is shown by the details on the notifier when secured with the syringe and allowing usage of the syringe to dispense the accurate dosage.
Claims21
A syringe, comprising:
- a dosage chamber having a dispensing opening for receiving and dispensing a dosage of medicine therefrom, and a plunger opening for receiving a plunger;
- a plunger located in the plunger opening and movable within the dosage chamber to enable partial withdrawal of the plunger from the dosage chamber to draw a medicine from a medicine container through the dispensing opening and into the dosage chamber, and subsequent partial or complete insertion of the plunger into the dosage chamber to dispense the medicine from the dosage chamber through the dispensing opening, said plunger comprising a longitudinal shaft;
- a verification chamber comprising a transparent cylindrical chamber sized to receive the medicine container through an opening at a proximal end thereof and sized to fit within the dosage chamber, wherein the verification chamber is closed at a distal end thereof, which is integral with or permanently fixed to the proximal end of the longitudinal shaft of the plunger, wherein the proximal end is an end closer to the plunger opening and a distal end is an end closer to the dispensing opening, wherein the verification chamber is configured to receive the medicine container in a used state;
- and
- a tamperproof locking mechanism operable to prevent removal of the medicine container from the verification chamber;
- wherein the verification chamber is configured to allow visual inspection of the medicine container locked within the verification chamber so that the medicine that was drawn from the open ampoule into the dosage chamber can be securely identified and verified by visual inspection of an identifier of the medicine container locked within the verification chamber.

- and
- a tamper-resistant closure operable to block the opening of the verification chamber and prevent or at least inhibit removal of the medicine container from the verification chamber;
- wherein the verification chamber is configured to allow visual inspection of the medicine container locked within the verification chamber so that the medicine that was drawn from the open ampoule into the dosage chamber can be securely identified and verified by visual inspection of an identifier of the medicine container locked within the verification chamber.
