  • Patent number: 10603459
    Abstract: A vaporizer and vaporizer cartridge for inhaling vapors from vaporized oil. The vaporizer has a mouthpiece for use by a user to inhale the vapors. The mouthpiece is connected to a cartridge which contains the oil to be vaporized and the apparatus for vaporizing the oil. The vaporizer cartridge contains a reservoir of the oil which flows down to a wick, which is heated by a heating coil to a temperature necessary to vaporize the oil. Under the wick is a residue basin which collects any oil which fails to vaporize. The residue basin is placed at an optimal distance from the wick such that when the next user initiates another draw on the vaporizer, the un-vaporized oil in the residue basin is vaporized. Below the cartridge is a battery component that provides power to a heating coil which heats the wick to vaporize the oil. Air flows up from below the cartridge on one side, then cross-flows across the wick and residue basin, and up the other side of the cartridge to the mouthpiece.

  • Patent number: 10603454
    Abstract: A tracheostomy tube assembly comprises an outer tracheostomy tube (1) and an inner cannula (20) fitted in the tube. The machine end of the inner cannula has a collapsible region (22) formed by a plurality of curved or bent struts (26) extending parallel with one another between a machine end collar (28) and a patient end collar (27). The struts (26) carry outwardly-projecting catches (23) arranged to engage a rib (24) extending around the inside of a hub (16) at the machine end of the tube and thereby resist removal of the cannula from the tube. The inner cannula (20) is removed by twisting the machine end collar (28) so that the struts (26) collapse inwardly and thereby disengage the catches (23) from the rib (24).

  • Patent number: 10589045
    Abstract: A system for assessing lung function in a patient is enclosed. The oxygen delivery system in the system (e.g., a ventilator or portable standalone system) preferably includes an oximeter sensor for receiving SpO2 from a patient. The assessing lung function in a patient includes an FiO2 adjust algorithm operable in logic circuitry in the ventilator that can control an oxygen fraction FiO2 provided to the patient in a closed loop fashion. In a preferred example, the algorithm controls FiO2 using the SpO2, but also displays a ratio of SpO2-to FiO2 (S/CLCF) as a function of time. One or more S/CLCF ratio threshold may be used to allow the clinician and/or the algorithm to understand a degree of lung injury, and to allow the algorithm to adjust FiO2 appropriately. Preferably, the algorithm keeps SpO2 to a range of 88-95%.
