摘要： Some embodiments provide for humidifier control systems and methods configured to adjust power to a heater plate in a surgical humidifier to account for changes in flow rate to provide a consistent output, to provide functionality for different modes of use, and to provide accurate control over temperature and/or humidity at relatively low flows. The humidifier control system can receive a flow rate reading and determine a power requirement corresponding to the received flow rate reading, wherein the power requirement is one of a plurality of set points which correspond to ranges of flow rates. The humidifier control system can determine a mode of use based at least in part on the flow rate reading. The humidifier control system can provide electrical power to the heater plate according to the power requirement and/or the mode of use.

摘要： A droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The droplet delivery device includes a housing, a reservoir, and ejector mechanism, and at least one differential pressure sensor. The droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The droplet delivery device is then actuated to generate a stream of droplets having an average ejected droplet diameter within the respirable size range, e.g, less than about 5 μm, so as to target the pulmonary system of the user.

摘要： A device, for dispensing an anesthetic into a gas stream, has a gas inlet, via which gas to be enriched with anesthetic and coming from a gas source flows in and with a gas outlet, via which gas enriched with anesthetic flows out to a patient port. A heating element, for heating the gas stream, is arranged upstream of an evaporation chamber, for dispensing an anesthetic into the gas stream, between the gas inlet and the gas outlet. The heating element is actuated by a control unit such that heat is fed to the gas to be enriched with anesthetic for evaporation of the anesthetic located in the evaporation chamber as a function of at least one status parameter of the gas to be enriched with the anesthetic and/or of the gas at least partially enriched with the anesthetic.

摘要： A personal air filtration device and methods of using the same for providing a zone of filtered air proximate a breathing zone of a user are described. A blower provides an air flow to a head support which delivers the air flow to a zone proximate the users head. The air flow passes through a filter. The filter can be a point of delivery filter disposed about an air permeable surface of the head support. The delivered air flow can provide a laminar air flow defining a zone of filtered air about the user's breathing zone.

摘要： An apparatus for delivering breathable gas to a patient includes a flow generator to generate a flow of breathable gas; a humidifier chamber to contain a supply of water; a first flow path to deliver the flow of breathable gas from the flow generator to the humidifier chamber; a second flow path to deliver the flow of breathable gas from the humidifier chamber to a patient interface; and a wicking element and/or a flat, elongate heating element provided at least in the humidifier chamber. A method of delivering a flow of breathable gas to a patient includes generating a flow of breathable gas; and humidifying the flow by passing the flow over a supply of water. Humidifying the flow includes heating the supply of water and/or the flow with a heating element in thermal contact with the water and/or the flow before passing the supply of water, the flow over the supply of water, and/or the flow after passing the supply of water; and controlling a voltage applied to the heating element to control the humidity of the flow. A tube for use in delivering a flow of breathable gas to a patient includes a circuit including electrically conductive ink provided on an inner surface and/or an outer surface.
