    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 variable flexibility adhesive system may adhere a surface of a medical infusion device to the skin of a user. The system may be configured to hold a location on the surface stationary with respect to a site on the user's skin. The system may include an adhesive substrate for adhering to the user and an interface where the substrate is held to the surface of the device. The interface may totally and/or partially surround the stationary location. A skirt of the substrate may totally and/or partially surround the interface. Parts of the skirt may be stiffened. Optional features may include tabs for activation of the adhesive and/or a location for peeling the infuser to away from the skin. Additionally or alternatively, the interface may have variable flexibility. Additionally or alternatively, the stiffener may include a plastic layer.

    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.

    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.
