  • Publication number: 20240108844
    Abstract: A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

  • Publication number: 20240094195
    Abstract: The present invention relates to a method for assessing respiratory viral infections, the method includes preparing one or more precision-cut human bronchial tissues; exposing a cilia-rich epithelium within the precision-cut human bronchial tissues to establish an ex vivo model of human bronchus for viral infections; assessing infectivity, tropism, and pathogenesis of one or more respiratory viruses in the ex vivo model; and providing a semi-quantitative and normalized approach to supplement data from the ex vivo model of human bronchus for pandemic risk assessment of the one or more respiratory viruses. The present invention involves micro-dissection of bronchial tissues to expose the cilia-rich epithelium for ex vivo virus infection, along with a semi-quantitative approach for analyzing virus tropism and replication competence.

  • Publication number: 20230390587
    Abstract: An x-ray irradiation system includes a first x-ray tube constructed and arranged to be able to irradiate an object with at least a portion of a first x-ray beam emitted from the first x-ray tube, and a second x-ray tube constructed and arranged to be able to irradiate the object with at least a portion of a second x-ray beam emitted from said second x-ray tube simultaneously with said first x-ray beam. The first and second x-ray tubes are arranged such that the first and second x-ray beams are incident on, and intersect within, the object at respective first and second oblique angles to define a target volume such that a dose rate is substantially uniform as prescribed within said target volume.
