    Abstract: Apparatus is described for administering a substance to a subject. A vial contains the substance and a stopper is disposed within the vial and is slidably coupled to the vial. A first threaded element is (a) rotatable with respect to the vial and (b) substantially immobile proximally with respect to the vial during rotation of the first threaded element. A second threaded element is threadedly coupled to the first threaded element. At least a distal end of the second threaded element is substantially non-rotatable with respect to the vial, and the distal end of the second threaded element defines a coupling portion that couples the second threaded element to the stopper. The first threaded element, by rotating, linearly advances the stopper and at least the distal end of the second threaded element toward a distal end of the vial. Other embodiments are also described.

    Abstract: A method and system for a drug delivery device with multiple status indicators is disclosed. For example the device may include an operator indicator and/or second indicator. The indicators may be seen in one location. For example they may be viewed through one optical path. Optionally the operator indicator may attract attention. The operator indicator may give information that is pertinent to operation of the device to an operator of the system. The operator indicator may have an encoded output signal. Optionally a second indicator may convey information that is not conveyed by the user operator by the operator indicator, for example information that is not pertinent to the regular operation of the machine. Alternatively or additional, the second indicator may function at times when operator indicator is not functioning.

    Abstract: An alignment assembly for a cartridge interface of a drug delivery device is disclosed. The assembly optionally includes a coupling for opening fluid communication between the cartridge and the delivery device. For example, the coupling optionally includes a cannula insertable through a septum of the cartridge. The assembly may include a guide for positioning the cartridge and/or an access channel thereof within a first precision of a loaded position. The assembly optionally includes a cartridge engagement fitting (for example a gripping expander sleeve collar) attached to the coupling. Optionally when the cartridge is engaged to the fitting, the coupling is retained in connection with the access channel to within a second precision. The second precision is optionally higher than the first precision. In some embodiments one or more compliant supports movably retain the fitting oriented to engage the cartridge when the access channel is in the loaded position.

    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: Medical devices including a vial adapter with an inline dry drug module for use with a vial, a needleless syringe and a carrier liquid for filling the needleless syringe with an injection solution for injection to a patient. The inline dry drug modules include a dry drug storage component for storing a dry drug dosage and a uniform carrier liquid distribution component for promoting uniform contact of the dry drug storage component by the carrier liquid to form an injection solution from the dry drug dosage. The inline dry drug modules can include a discrete dry drug storage component and a discrete uniform carrier liquid distribution component or a dual purpose component for both drug storage and uniform carrier liquid distribution. The vial adapters can be provided in vented or non-vented versions.

    Abstract: Dual vial adapter assemblages similar to U.S. Pat. No. 6,558,365 to Zinger et al. and U.S. Pat. No. 8,752,598 to Denenburg et al. and including a quick release drug vial adapter with an upright finger grip extension pair oppositely for manually urging inwards towards one another for releasing same from a drug vial. The quick release drug vial adapter ensures correct usage of a dual vial adapter assemblage by preventing immediate removal of a drug vial adapter from a drug vial after forming a liquid drug therein thereby assisting a healthcare provider to follow an administration protocol requiring an initial aspiration of some liquid drug for immediate administration purposes to a patient prior to subsequent infusion of the liquid drug remainder.
