Abstract: A needle hub assembly for a pen needle includes a needle hub, an inner shield and an outer cover. The open end of the outer cover is closed by a removable seal to access the needle hub. The needle hub has a body with a shoulder and a tower extending from the body for supporting a cannula. The inner shield fits over the tower and the cannula and includes a flange that has an outer dimension complementing the outer dimension of the needle hub and contacts the shoulder of the needle hub in the assembled condition. The outer cover encloses the needle hub and the inner shield and includes a stop member on an inner surface that contacts the flange of the inner shield to capture the inner shield between the shoulder of the needle hub and the outer cover.

Abstract: A pen needle assembly (10) includes a pen needle (12) with a hub body (16) having a needle shield (28) that covers a needle (26) and can be retracted to expose the needle during injection and return to the extended position after use and locked in the extended position. A spring (56) is provided to rotate the needle shield after use to a locked position. A locking member (84) can be provided on the needle shield that cooperates with the hub body (16) to prevent rotation after use. An attachment mechanism (38) for the pen needle provides a sensory indication when a needle-bearing hub body (16) is seated on a pen and limits further rotation of the pen needle relative to the delivery device.

Abstract: Induction heating from an induction coil (108) is used to separate a metal medical sharp (144) from its holder (142) by applying a high-frequency oscillating magnetic field that excites eddy currents and resistance heating in the sharp. The heated metal sharp melts the adhesive or plastic securing the sharp to its holder. The use of induction heating is advantageous in that it does not require direct contact between the electrical circuit and the sharp or its holder. The heating can also act to sterilize the sharp and thereby render it less hazardous at the same time that it separates the sharp from its holder. The induction coil can have a stepped or conical shape to concentrate the RF energy at the interface between the metal sharp and its holder.

Abstract: User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen. Embodiments include a needle-bearing hub having a circumferentially oriented flexible tab that engages a radially inward rib on an outer cover to assist in attaching a pen device to the pen needle.

Abstract: A syringe includes a syringe body having a syringe barrel for receiving and administering a medicament, a hollow needle fluidly communicating with the syringe barrel, and a needle adapter disposed on the syringe body. An outer diameter of the needle adapter is wider than an outer diameter of the syringe barrel, and a distal surface of the needle adapter is substantially flat. The needle adapter facilitates a flush alignment of the distal surface of the needle adapter with at least one of a vial stopper and a vial stopper holder of a medicament vial to ensure that a tip of the needle is properly inserted into the vial to aspirate the medicament within the vial.
