Abstract: Apparatus and associated methods relate to an apparatus for generating a periodic fluid pressure profile. The apparatus may include an enclosure extending longitudinally between an enclosure proximal end and an enclosure distal end. The enclosure may include a radial enclosure port. The apparatus may include an inner pressure profile module (IPPM) configured to rotate about a longitudinal axis and rotate inside of a longitudinally extending central cavity of the enclosure. The IPPM may include a radial IPPM aperture configured to longitudinally align with the radial enclosure port, and a longitudinally extending central cavity of the IPPM. The radial IPPM aperture may have a predetermined aperture shape. The apparatus may include a barrel configured to remain stationary in a longitudinally extending central cavity of the enclosure. The barrel may include a proximal radial barrel aperture and a distal radial barrel aperture.

Abstract: Example techniques and systems include managing delivery of a substance into an inhaled stream of air from a patient. For example, a system may include a housing configured to accept a medication canister containing a medication, the housing comprising a dispensing portion, a sensor configured to sense air flow within the dispensing portion, and a processor configured to transmit a signal indicative of the sensed air flow, wherein information associated with use of the pulmonary medication dosing device is generated by the computing device and based on the transmitted signal.

Abstract: To determine the heat output efficacy of a heating device such as a convective warming blanket, a conduit structure is constructed to have coiled metal tubings that form the head, torso and other non-moving parts of a person analog. Flexible tubings interconnect the metal tubings to establish a continuous conduit between an inlet and an outlet of the structure, so that a fluid having a particular heat capacity may flow uninterrupted through the conduit structure. Respective temperature sensors at the inlet and outlet measure the input and output temperatures of the fluid. Using the flow rate, the heat capacity and the respective temperatures of the fluid measured at the inlet and outlet, the heat output efficiency of the blanket may be calculated. A FLIR camera may be used to obtain an IR image to confirm the heat output efficiency of the blanket.

Abstract: Embodiments of a delivery device, a kit comprising the delivery device, and methods of using the same are presented. In one embodiment, the delivery device includes a syringe assembly defining two or more reservoirs each configured to hold a dispensable material. Additionally, the delivery device may include a delivery tip. The delivery tip may have an inlet, an outlet, a central flow-restricting portion, and one or more channels adjacent to the central flow-restricting portion that provide fluid communication between the inlet and the outlet, the one or more channels including a section that tapers inwardly toward the outlet. In one embodiment, the delivery device is configured such that if the two or more reservoirs hold dispensable material then the syringe assembly can be actuated to dispense the dispensable material from the two or more reservoirs substantially simultaneously into the inlet.
