Abstract
Systems and methods of a dosage verification system are disclosed that can be used by a healthcare worker or an individual self-administering an injection to create a digital record verifying the dosage of a medicinal fluid drawn into a syringe prior to an injection. The dosage verification system includes a medical syringe and an imaging device configured to view and selectively capture, process, store, and transmit a digital image of the syringe from which the volumetric dose of medicinal fluid drawn into the fluid chamber of the barrel can be determined and/or verified prior to an injection.
Claims48
A system for verifying dosage accuracy of a medicinal fluid, the system comprising:
- a syringe comprising a barrel, a fluid chamber disposed inside the barrel, a plunger slidably engaging the fluid chamber, and a needle, the syringe configured to draw an actual dosage of the medicinal fluid into the fluid chamber by movement of the plunger rearwardly in the fluid chamber;
- and
- a first data set comprising pre-determined volumetric proportions of the fluid chamber between a substantially full volume when the plunger is in a fully extended position relative to the barrel and a substantially empty volume when the plunger is in a fully inserted position relative to the barrel, the first data set configured to be saved to a processor or accessed by the processor for use in a software application to determine a volume of the actual dosage based on a digital image of at least a portion of the syringe after the actual dosage is drawn into the fluid chamber and a position of the plunger relative to the barrel is between the fully extended position and the fully inserted position.
A method of verifying a dosage accuracy of a medicinal fluid, the method comprising:
- drawing an actual dosage of the medicinal fluid into a fluid chamber of a barrel of a syringe, a plunger slidably engaging the barrel, and a hypodermic needle;
- positioning a digital imaging device relative to the syringe, wherein the digital imaging device comprises a camera, a processor, and a software application executed by the processor, configured to selectively view, capture, and store a digital image of the syringe;
- capturing the digital image of the syringe;
- and
- processing the digital image to determine a volume of the actual dosage of the medicinal fluid based on a position of the plunger relative to the barrel and pre-determined volumetric proportions of the fluid chamber between a substantially full volume when the plunger is in a fully extended position relative to the barrel and a substantially empty volume with the plunger is a fully inserted position relative to the barrel.
