  • Patent number: 11504481
    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.

  • Patent number: 11426518
    Abstract: An inventive drug delivery system includes a reservoir that holds a drug to be administered. A drug applicator injects or infuses the drug, and a pump generates a flow of the drug from the reservoir to the drug applicator. A control system has a pressure sensor that measures pressure signals indicative of resistance against the flow of the drug and a processor is in communication with the pressure sensor. The control system detects with the pressure sensor a pressure signal indicative of the resistance against the flow of the drug while the drug is being administered and compares the measured pressure signal to a reference value. The control system also generates display data and provides it to an output device when the measured pressure signal exceeds the reference value. The display data includes a scheduled test reminder for a glucose level test that is communicated to an output device.

  • Patent number: 11400226
    Abstract: An injector includes a housing and an activation button assembly movably mounted thereto and translatable from an unactuated position to an actuated position. A cartridge door is configured to receive therein a cartridge containing a substance to be dispensed, and is movably mounted to the injector housing between open and closed positions. A deflectable interference member is mounted within the injector housing and, in a resting position, blocks movement of the activation button assembly from the unactuated to the actuated position thereof. The activation button assembly is configured to activate the injector when in the actuated position, and is movable from the unactuated position to the actuated position solely upon deflection of the interference element out of the resting position thereof. The cartridge door, when in the closed position thereof and having the cartridge received therein, deflects the interference element out of the resting position thereof.
