A syringe (200, 400) for use in a medication delivery device (100) comprises a vial. The vial (201, 411) comprises a chamber (206). The chamber is configured to receive a piston or plunger (205, 416). The syringe further comprises a needle attachment point (202), for the attachment of a hypodermic needle (204). The chamber is offset from the needle attachment point.

Disclosed is a Huber needle assembly that may include an upper body connected to a lower body, the assembly being structured to retain a needle for insertion/extraction of the needle into/from an insertion site. The upper body can statically retain the needle while the lower body may slidably receive the needle. The lower body can further include a catch that engages a tip of the needle and/or misaligns the tip of the needle with a needle aperture of the lower body to place the assembly in a safety-lock position, preventing rebound, needle-stick injury, and/or any type of exposure of the needle tip to an environment outside of the lower body. The assembly can further bias the needle in a direction so as to prevent re-emergence of the needle tip after being withdrawn into the lower body.

A fluid transfer device such as a syringe may include a fluid chamber in communication with a male connector tip. The male connector tip is tapered to form a friction fit when inserted in a corresponding female hub. A disconnecting member, e.g., in the form of a lever member has a front surface moveable along the male connector tip between a first position proximal to the fluid chamber and a second position spaced from the first position towards a distal end of the male connector tip so as to release the friction fit. A catch is arranged to catch the female hub after it has been released from the friction fit by the lever member moving towards the second position. The catch may be released when the lever member pivots back towards the first position under the resilient bias of a spring tongue.

An adapter for use with an injection device includes a first end, a second end and a first longitudinal axis extending from the first end and the second end. The adapter also includes a chamber defined by a sidewall between the first end and second end and a nozzle having a passageway extending through the sidewall, the passageway having an input at the chamber, an output at an outer surface of the body and a passageway axis extending from the input to the output, the passageway axis being angularly offset from the longitudinal axis of the channel. A cartridge can include such an adapter.

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.

Low-profile fluid injection systems and methods for injecting fluid into a tumor within a body comprising an elongate member, a plurality of fluid delivery members, and a plurality of fluid reservoirs. Each of the plurality of fluid reservoirs may be fluidly coupled to a single of fluid delivery lumen of a single fluid delivery member such that each of the fluid delivery members is fluidly independent of every other fluid delivery member. The plurality of fluid delivery members may be configured to extend out of a distal end of the elongate member into the tumor when the system is positioned in the body of a patient. A fluid delivery mechanism may be operably coupled to the plurality of fluid reservoirs in order to deliver fluids from the plurality of fluid reservoirs to the plurality of fluid delivery members and inject the fluids into the tumor.

A syringe (100) comprising a barrel (111) with a lumen is provided. The barrel (111) is adapted to contain a drug, the barrel (111) having a distal end wall portion (198) and a tubular wall (112) extending proximally from said distal end wall portion (198), whereby the barrel (111) extends along an axis (1000). The distal end wall portion (198) has an opening (199) extending into a syringe head (140) adapted to receive a syringe needle, said syringe head (140) having a lumen smaller in transversal cross-section than the barrel lumen; the syringe (100) further comprising: a plunger (196) extending along the axis, said plunger shaft being displaceable along the axis (1000) within said barrel (111).
