Abstract:
A liquid drug transfer device for use with an injection vial which includes a vial adapter having a puncturing cannula for puncturing a vial stopper and a fluid transfer port in flow communication with the puncturing cannula. The vial adapter includes set-up vial retention flex members for vial retention purposes in a set-up position without puncturing an injection vial and activation vial retention flex members for vial retention purposes in an activation position puncturing the injection vial.
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:
An aspect of some embodiments of the current application is a doorstop to a drug delivery apparatus that encourages a user of the apparatus to perform the proper usage steps in the proper order. For example, a user may be expected to receive an injector in a transport state, open it to an open state, insert a cartridge, and/or close the cartridge before operation. The doorstop may have an obstructing mode, optionally preventing closing of the door. The cartridge may optionally have a non-obstructing mode allowing closing of the door. Inserting the cartridge may optionally cause a doorstop to move from the obstructing mode to the non-obstructing mode. In the non-obstructing mode the doorstop may optionally prevent removal of the cartridge.
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 telescopic female drug vial adapter including a spike component telescopically mounted on a skirt component for snap fit on and puncturing a drug vial in an actuated position. The telescopic female drug vial adapter is particularly suitable for implementation in a vented version to avoid wetting of its air filter during aspiration of liquid contents from a drug vial.
Abstract:
Liquid drug transfer devices with universal drug vial adapters for use with a drug vial of a small drug vial and a large drug vial. Some universal drug vial adapters employ the same generally opposite upright flex members for clamping a small drug vial and a large drug vial. Other universal drug vial adapters include a set of minor flex members for clamping a small drug vial and a set of major flex members encircling the set of minor flex members for clamping a large drug vial whereupon the large drug vial underlies the set of minor flex members. Liquid drug transfer devices with a universal injection port connector for attachment on an injection port of an infusion bag.
