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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The syringe according to claim 1, wherein the medicine container is of a type that has a frangible seal that is broken to access the medicine stored therein, and the verification chamber acts as a sharps container to protect a user of the syringe from a broken seal of the medicine container locked within the verification chamber. ### Claim 3 (depends on 2) The syringe according to claim 2, wherein the medicine container is an ampoule. ### Claim 4 (depends on 1) The syringe or assembly according to claim 1, wherein the verification chamber includes a transparent window to allow visual inspection of the medicine container locked within the verification chamber. ### Claim 5 (depends on 1) The syringe or assembly according to claim 1, wherein the verification chamber contains an identifier of the medicine in the dosage chamber, and an identifier of a solute in the dosage chamber. ### Claim 6 (depends on 2) The syringe or assembly according to claim 2, wherein the verification chamber contains an identifier of the medicine in the dosage chamber, and an identifier of a solute in the dosage chamber. ### Claim 7 (depends on 3) The syringe or assembly according to claim 3, wherein the verification chamber contains an identifier of the medicine in the dosage chamber, and an identifier of a solute in the dosage chamber. ### Claim 8 (depends on 4) The syringe or assembly according to claim 4, wherein the verification chamber contains an identifier of the medicine in the dosage chamber, and an identifier of a solute in the dosage chamber. ### Claim 9 (depends on 1) The syringe or assembly according to claim 1, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 10 (depends on 2) The syringe or assembly according to claim 2, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 11 (depends on 3) The syringe or assembly according to claim 3, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 12 (depends on 4) The syringe or assembly according to claim 4, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 13 (depends on 5) The syringe or assembly according to claim 5, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 14 (depends on 6) The syringe or assembly according to claim 6, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 15 (depends on 7) The syringe or assembly according to claim 7, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 16 (depends on 8) The syringe or assembly according to claim 8, wherein the tamperproof locking mechanism includes an entrapment mechanism or a one way ratchet means. ### Claim 17 (depends on 1) A method of identifying a medicine in or dispensed from a dosage chamber of a syringe according to claim 1, comprising: drawing the dosage of medicine from the medicine container into the dosage chamber of the syringe by partial withdrawal of the plunger of the syringe from the dosage chamber; inserting the medicine container into the verification chamber of the syringe; and operating the tamperproof locking mechanism to prevent removal of the medicine container from the verification chamber, visually inspecting an identifier of the medicine container locked within the verification chamber so as to securely identify and verify that the medicine that was drawn from the medicine container into the dosage chamber. ### Claim 18 (depends on 17) The method according to claim 17, wherein the medicine container is of a type that has a frangible seal that is broken to access the medicine stored therein, and the verification chamber acts as a sharps container to protect a user of the syringe from a broken seal of the medicine container locked within the verification chamber. ### Claim 19 (depends on 18) The method according to claim 18, wherein the medicine container is an ampoule. ### Claim 20 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 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. ### Claim 21 (depends on 1) A kit comprising the syringe of claim 1 and the medicine container containing the medicine from which the dosage of medicine is drawn.
