An electronic system (200) connectable to a medication delivery pen (4) and a needle assembly (2, 102), the electronic system (200) exchanging data regarding a medicament traveling from the medication delivery pen (4) to the needle assembly (2, 102), the electronic system (200) comprising a hub (202) having a spike (204) that is configured to engage the medication delivery pen (4) and pierce a reservoir septum of the medication delivery pen (4), a flow sensor (220) that is in fluid communication with the hub (202) to measure flow data of the medicament, a circuit board (250) electrically contacting the flow sensor (220) to process and transmit the flow data, the circuit board (250) including a fluid path hole (254) to route a flow of medicament, and a septum body (270, 284) that is configured to provide fluid communication between the flow sensor (220) and one of a plurality of needles (40, 124) of the needle assembly (2, 102) to administer the medicament to a patient.

An attachable needle assembly (2) is disclosed for use on a medication delivery pen (4). The needle assembly (2) includes a housing (8) enclosing a hub (12) that is configured to engage the medication delivery pen (4), a plurality of needles (18) configured to pierce a reservoir septum (6) of the medication delivery pen (4), a selection ring insert (30) that rotates and identifies which needle (24) of the plurality of needles (18) is to be selected, and a selection ring (36) that applies a force to expose the selected needle (24). When the housing (8) is in a first position, the plurality of needles (18) is not exposed, and when the housing (8) is in a second position, one of the plurality of needles (24) is exposed for medicament delivery.

The present disclosure relates to drug-delivery apparatuses, and in particular, to a drug-delivery apparatus with a fluidic subsystem that can be used to deliver multiple injections to a patient from a drug container storing a drug fluid. The fluidic subsystem may include multiple injection-needle compartments and re-sealable septa to allow multiple accesses to the drug container, while also preserving the sterility of the drug fluid and of the fluid pathway through which the fluid is delivered to a patient. In some embodiments, the fluidic subsystem may be used to deliver drug fluids that do not contain any preservatives (e.g., non-preserved drugs).
