    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 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: In accordance with some embodiments of the present invention an automated injection device may be loaded with a standard type syringe and/or hypodermic needle. Optionally the syringe may be supplied loaded with medicine and/or covered with a sterile needle cover. The syringe may be loaded into the injector with in a sterile state with needle cover in place. Injector may include for example a fastener (for example an adhesive base). In some embodiments, the fastener may assist a user to hold injector steady on the skin of a patient for an extended period. For example, injector may be used to give injections of volume ranging between 0.5 and 3.0 ml over a time period ranging between 30 sec to 180 sec.

    Abstract: A status of a battery operated infuser may be detected by measuring a controlled input parameter. The measurement may be used to determine a magnitude of the input parameter and a parameter of the control. For example, control of power input to a motor may be by pulse density modulation. An integral of current over time may serve as a measure of current magnitude and pulse density. The result of the integral may be used to determine the status of the injector. The status may include normal functions for example start of pumping and/or malfunctions such as occlusion or drive disengagement.

    Abstract: A plunger seal for a drug delivery device may have a mobile and an enhanced sealing parked state. Optionally, the cartridge is stored with the plunger seal in the parked state. Optionally, drug discharge occurs with the plunger seal in the mobile state. For example in the parked state there may be increased normal force between the plunger seal and an inner wall of the cartridge. Optionally there is limited deformation of the plunger seal between the parked and mobile states. Optionally the plunger seal is biased to the parked state. Optionally, a distal force switches the plunger seal to the mobile state. For example, the plunger seal may have an inner cavity that is expanded radially by core. A biasing element optionally biases the core wedging it proximally to the parked state. A distal force on the core may push it distally to the mobile state.
