Cover for liquid delivery system with integrated plunger position sensing using focused optical beam and linear potentiometer
11529471 · 2022-12-20 · ·

A sliding cover for a liquid delivery device, such as a cap (100) for a pen injector (200), incorporates a set of sensors including an optical sensor (110) with an output which changes during uncapping or capping motions on passing of a plunger (220) of the pen injector. This output is used together with a position sensor (120) to determine the position of the plunger along a cylinder (210) of the liquid delivery device. By monitoring changes in the plunger position, the quantity of dosages delivered by the liquid delivery device can be determined, displayed, stored and/or transmitted to an external device for further data processing or storage. Preferred implementations of the invention employ optical sensors with a converging beam (115), and/or position sensors employing linear potentiometer strips (132).

20220395640 · 2022-12-15 ·

A device is presented having an electronic circuit, where the device can be a medicament delivery device or a medicament delivery device add-on component that includes an electronic circuit having a temperature sensor configured to measure a temperature, where the electronic circuit is configured to passively remain in a first mode when the temperature is on a first side of a set temperature and to transition to a second mode when the temperature transitions to a second side of the set temperature. In some embodiments, the electronic circuit can have one or more of a feedback portion configured to switch from a first state to a second state in response to the electronic circuit transitioning from the first mode to the second mode, a lock, and a recordal portion to record when the electronic circuit transitions from the first mode to the second mode.

Gas Sterilizable Syringes Having Apertures Covered by Gas Permeable Barriers for Enabling Ingress and Egress of Sterilization Gases While Preventing Leakage of Flowable Materials

A gas sterilizable syringe includes an enclosure having walls that define a fluid chamber. A flowable material is disposed within the fluid chamber of the enclosure. A plunger is assembled with the enclosure and is moveable toward a distal end of the enclosure for dispensing the flowable material. One or more apertures are formed in at least one of the walls of the enclosure. A gas permeable barrier covers at least one of the apertures formed in at least one of the walls of the enclosure for enabling sterilization gases to pass through the at least one aperture covered by the gas permeable barrier while preventing the flowable material from passing through the at least one of aperture. The gas permeable barrier is permeable to the sterilization gases and impermeable to the flowable material disposed within the fluid chamber of the enclosure.

Drug delivery device and method of operation
