Abstract:
Extension rods of a telescoping assembly (TSA) may be assembled in a single direction. The rods may optionally be threaded together from a reverse extended configuration. The rods may optionally resist disattachement during extension. The inner rod may optionally included a leading fastener and/or the outer rod may optionally include a rear fastener. Each rod may optionally be molded as a single piece. End caps may optionally be added to the TSA after extension of the rods. An end cap may optionally include a rotation stopper. In some embodiments the TSA may include a supporting shoulder.
Abstract:
A drug container closure for mounting on an open-topped drug container to form a ready-to-use drug reconstitution assemblage for use with a needleless syringe. The drug container closure includes a drug container stopper for sealing the drug container and a fluid transfer member with an integral needleless syringe connector and a puncturing cannula. The fluid transfer member is manually disposed along a diametric inverted L-shaped track pair from an initial non-puncturing position to a puncturing position. The inverted L-shaped track pair includes one-way snap members to prevent a user returning the fluid transfer member to an earlier position and indicating progress of the user activation.
Abstract:
A system may regulate voltage supplied from a power source to an integrated circuit and/or an inertial device. A minimal voltage may be maintained in the integrated circuit by temporarily cutting off current to the inertial device to supply surges of voltage to the controller. Optionally voltage may be smoothed between said surges for example by adding capacitance and/or a current restrictor.
Abstract:
A method and device are disclosed for preventing a needle stick hazard in the event of a collapse of a protective needle flap of a portable drug pump. The device may include a needle guide, a secure space and/or a shield. A point of a needle is optionally deflected into a secure space upon collapse of the protective flap. The space may optionally be shielded. Optionally, the support linking the needle to the pump may pivot and/or translate. Optionally, there may be an exposing position wherein the needle protrudes through an opening in the flap. Optionally, the opening may be non-circular.
Abstract:
A method and apparatus are disclosed for delivery of a drug to a recipient. In some embodiments, the delivery apparatus may unseal a drug containing reservoir. In some embodiments, the delivery rate may be controlled and/or adjustable. Optionally the apparatus may be disposable. Optionally, the apparatus may have a low profile and/or be wearable and/or attachable to the recipient. Optionally, discharge of the drug and/or unsealing of the reservoir may be driven by a plunger moving parallel to the base of the apparatus. Optionally, the apparatus may release a hypodermic needle into the recipient. Optionally, release of the hypodermic needle may be in a direction non-parallel and/or orthogonal to the direction of movement of the plunger. Optionally, prior to release, the hypodermic needle may be preserved in an aseptic state by a needle opening septum sealing a needle opening. Optionally, upon release, the hypodermic needle may pierce the needle opening septum.
Abstract:
An apparatus (110) includes an activation mechanism (20) and a safety latch (122). The activation mechanism is operative to deploy a needle (116) to protrude out of a housing (112), the needle (116) having a longitudinal axis. The safety latch (122) is movably mounted on the housing (112) and formed with a needle opening (129) to allow the needle (116) to pass therethrough. The safety latch (122) has a first position wherein the needle (116) is aligned to pass through the needle opening (129) and a second position wherein the safety latch (122) is moved with respect to the housing (112) such that the needle (116) is blocked from movement in a direction parallel to the longitudinal axis thereof by a portion of the safety latch (122) distanced from the needle opening (129).

Abstract:
A method of securing an assembly of a drug delivery system, comprising: configuring at least a first component and a second component of the assembly in a closed configuration ready for placement into the drug delivery system; installing an assembly key including a locking element on the assembly to secure the assembly in said configuration; and, transporting the assembly with the assembly key installed
Abstract:
A cartridge insertion assembly including apparatus with a pathway formed therein, a cartridge including a cartridge coupling element connectable to an activation mechanism disposed in the apparatus operative to cause a substance contained in the cartridge to be metered out of the cartridge, and a door pivoted to the apparatus that includes a door coupling element arranged with respect to the cartridge such that when the door is in a fully closed position, the door coupling element couples the cartridge coupling element with a coupling element of the activation mechanism.
