A system is disclosed that includes a holder having a pressurized chamber and configured to secure an aerosol delivery device at least partially within the pressurized chamber. A test chamber is connected to the holder, the test chamber having an inlet allowing an aerosol from the aerosol delivery device to enter the test chamber.

Provided herein are methods, devices, systems, and computer readable medium for delivering one or more compounds to a subject. Also described herein are methods, devices, systems, and computer readable medium for transitioning a smoker to an electronic nicotine delivery device and for smoking or nicotine urge relief.

A syringe pump is disclosed that includes a body, a syringe seat, a syringe actuator, a memory, and one or more processors. The syringe seat is coupled to the body. The syringe actuator is configured to actuate a syringe secured within the syringe seat. The memory is configured to store a plurality of instructions. The one or more processors, in accordance with the plurality of instructions, is/are configured to: prime the syringe pump in a prime phase; determine if an occlusion exists during the prime phase using a first test; stop the prime phase; initiate fluid delivery into a patient; enter into a start-up phase; determine if an occlusion exists using a second test during the start-up phase; transition from the start-up phase into a steady-state phase; and determine if an occlusion exists during the steady-state phase using a third test.

The invention relates to a trainer device for an autoinjector, comprising: a housing; a collet holder comprising a track; a safety cap removably connected to the collet holder; a cover member; a flex stem having flex arm; a cover member locking mechanism; and a resetting mechanism. The cover member further comprises a plastic sleeve or an elastomeric sleeve to prevent or inhibit the obstruction of the movement of cover member when the user accidentally holds the cover member during the actuation of trainer device.

A real-time drug injection time duration measurement system includes a sound transducer, a waveform shaping circuit operably coupled therewith, a pulse clamping circuit operably coupled with the waveform shaping circuit, and a timer operably coupled with the pulse clamping circuit. The sound transducer detects a first sound associated with drug delivery initiation and a second sound associated with drug delivery completion and is further converts the detected first and second sounds into a first electronic waveform and a second electronic waveform, respectively. The waveform shaping circuit converts the first and second waveforms into a first pulse and a second pulse, respectively. The pulse clamping circuit triggers upon receiving the first pulse and generate a regenerated pulse. The timer initiates upon receiving the regenerated pulse and stop upon receiving a subsequent regenerated pulse via the pulse clamping circuit.

An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.

The present disclosure is directed to a device for screening pre-filled syringes configured to determine whether a stopper position within each syringe falls within an acceptable tolerance prior to final assembly of a syringe into a corresponding autoinjector device, thereby ensuring proper fit of the syringe within the autoinjector device and further ensuring accurate delivery of a desired dose of fluid from the syringe during operation of the autoinjector.

A testing assembly for a drug delivery device is disclosed. The testing assembly can include a pressure vessel having a sealed pressure chamber that is configured to be pressurized to a predetermined pressure. The pressure vessel further defines an injection opening extending from an exterior thereof to the pressure chamber. A pierceable barrier extends over and seals the injection opening. The testing assembly further includes a measurement device disposed within the pressure chamber and a container aligned with the injection opening, such that the container is configured to collect a dose of a drug delivered via a drug delivery device through the pierceable barrier and the measurement device is configured to measure the dose of the drug.

A dry-powder inhaler comprising a housing comprising at least one air inlet to a first air passage and a second air passage extending from the first air passage and terminating in a mouthpiece; the housing thereby providing a continuous air passage through the at least one air inlet, the first and second air passages, and the mouth piece; a rigid, fixed, powdered-medicament reservoir comprising a base, the reservoir being associated with the first air passage, and together with the first air passage forming a powder chamber; wherein air passing through the powder chamber travels substantially parallel to an upper surface of the reservoir and powdered-medicament positioned on the base in the reservoir, the upper surface of the reservoir having a surface area, and the reservoir having a volume.

An interfacing structure is arranged to cooperate with a frame to contact with the skin of a patient. The interfacing structure includes a clip portion joined to a cushioning component. The frame is more rigid than the clip portion and the clip portion is more rigid than the cushioning component.
