Methods of actuating a needle array device can include causing fluid to move through flow channels to needle apertures that are spaced apart from an inflow aperture at different distances where flow channels that have approximately equal pathway lengths and where the fluid can reach tips of the needle apertures approximately simultaneously, which can provide an approximately equal dosage or fluid volume through the tips of the needle apertures.

A dosage verification system for use prior to administering an injection of a medicinal fluid drawn into a medical syringe, the system comprising a medical syringe having a barrel with an outwardly facing, flat indicia display surface, plunger having a plunger seal disposed inside and slidably engaging an inwardly facing wall of the barrel and a plunger handle projecting rearwardly from the barrel, and a hypodermic needle projecting forwardly from the barrel, all in combination with an imaging device configured to view and selectively capture, store or transmit a digital image of the plunger position relative to the barrel when a dose of the medicinal fluid is drawn into the fluid chamber of the barrel prior to an injection to verify and provide a record of the dosage drawn, and to alert a user prior to injection when an incorrect dosage is drawn into the fluid chamber of the syringe.

Methods, systems, and devices are disclosed for administering a medicament to a patient. In one aspect, a system includes an injection pen device in wireless communication with a mobile communication device. The injection pen device includes a housing including a chamber to encase a cartridge containing medicine, a dose setting and dispensing mechanism to set the mechanism to dispense a particular dose of the medicine from the loaded cartridge, a sensor unit to detect a dispensed dose based on positions and/or movements of the dose setting and dispensing mechanism, and an electronics unit in communication with the sensor unit to process the detected dispensed dose and time data associated with a dispensing event and to wirelessly transmit the dose data to a user's device. The mobile communication device provides a software application to provide the user with health information using the processed dose data.

Aspects of the present disclosure disclose a system for delivering a medication. In one aspect, the disclosure is directed to a kit that includes a medicine dispensing device with a label with a series of zones of varying widths, with each of the zones corresponding to a pre-determined volumetric dose of a drug that is correlated to at least one physical characteristic of a patient. In one specific example, the label is further affixed to the medicine dispensing device such that a smallest dose of the drug to be administered corresponds to a first zone that is proximate an opening through which the drug is to be dispensed.

A device may include a first medicine dosing device configured to facilitate delivery of a first medicine, the first medicine dosing device comprising color coded dosage zones. A device may include a second medicine dosing device configured to facilitate delivery of a second medicine, the second medicine dosing device comprising color coded dosage zones. A device may include a third medicine dosing device configured to facilitate delivery of a third medicine, the third medicine dosing device comprising color-coded dosage zones.

An accessory for use with a medicine delivery device includes a body configured to attach to a medicine delivery device and a user interface disposed on the body and configured to communicate information to a user. In aspects, the user interface includes first and second lights configured to be selectively illuminated and a first symbol associated with the first light. The first light and the first symbol together indicate an action to be performed when the first light is illuminated. In aspects, the user interface includes red, yellow, and green lights configured to be illuminated in sequential time periods after a dose using the medicine delivery device.
