Dosage verification system and method for safety syringe

A syringe dosage verification system for use prior to administering an injection of a medicinal fluid, the system comprising:

• a medical syringe comprising:
• a barrel having a nose, a finger flange, an outwardly facing flat indicia display surface disposed between the nose and the finger flange, and an inwardly facing surface defining a cylindrical fluid chamber inside the barrel, wherein an entirety of a volumetric scale is disposed on the outwardly facing flat indicia display surface between the finger flange and the nose of the barrel;
• a plunger having a plunger handle and a plunger seal disposed on a distal end of the plunger handle and slidably engaging the inwardly facing surface of the cylindrical fluid chamber of the barrel;
• and
• a forwardly projecting hypodermic needle;
• and
• an imaging device configured to view and selectively capture a digital image of a position of the plunger seal relative to the entirety of the volumetric scale disposed on the outwardly facing flat indicia display surface between the finger flange and the nose of the barrel when a dosage of the medicinal fluid is drawn into the cylindrical fluid chamber of the barrel and when at least a portion of the outwardly facing flat indicia display surface and the entirety of the volumetric scale disposed on the outwardly facing flat indicia display surface between the finger flange and the nose of the barrel are within a field of view of the imaging device to determine the dosage of the medicinal fluid drawn into the cylindrical fluid chamber of the barrel prior to administering the injection.

An apparatus for injecting a verified dosage of a medicinal fluid, the apparatus comprising:

• a syringe comprising:
• a barrel having a cylindrical fluid chamber and an outwardly facing flat indicia display surface comprising a volumetric scale, wherein a full length of the volumetric scale is disposed on the outwardly facing flat indicia display surface between a nose and a finger flange of the barrel, and wherein at least a portion of the full length of the volumetric scale overlies at least a portion of the cylindrical fluid chamber to facilitate simultaneous viewing of a medicinal fluid dosage disposed inside the cylindrical fluid chamber of the barrel and the full length of the volumetric scale disposed on the outwardly facing flat indicia display surface between the nose and the finger flange of the barrel;
• a plunger handle having a plunger seal slidably engaging the cylindrical fluid chamber of the barrel;
• and
• a hypodermic needle in fluid communication with the cylindrical fluid chamber of the barrel and extending from the nose of the barrel;
• and
• an imaging device configured to view and selectively capture at least one digital image of the medicinal fluid dosage disposed inside the cylindrical fluid chamber of the barrel and the full length of the volumetric scale disposed on the outwardly facing flat indicia display surface between the nose and the finger flange of the barrel and overlying the portion of the cylindrical fluid chamber of the barrel when at least a portion of the outwardly facing flat indicia display surface and the full length of the volumetric scale disposed on the outwardly facing flat indicia display surface between the finger flange and the nose of the barrel is within a field of view of the imaging device, from which a volumetric dosage of the medicinal fluid dosage drawn into the cylindrical fluid chamber can be determined prior to injecting the medicinal fluid.
