Abstract: An apparatus for destroying pathogens includes a housing, a platform, and a sanitizing unit. The platform has a window configured to permit passage of ultraviolet light therethrough. The housing is configured to receive the platform. The sanitizing unit is disposed below the platform and includes a track assembly, at least one light bar coupled to the track assembly and a motor assembly configured to move the light bar along the track assembly. The light bar includes a first ultraviolet (UV) light emitting source configured to emit UV light towards the platform.

Abstract: A method and apparatus for making noncommercial amounts of a gas a liquid using a Joule-Thomson device. The device uses a precooler, a compressor, a Joule-Thomson valve and a thermally insulated housing.

Abstract: A data collection and processing system provides user and apparatus information from a CPAP apparatus to a remote location. The system also allows the operating settings for the CPAP apparatus to be remotely programmed. Information is collected and stored in a digital memory in the CPAP apparatus. The CPAP apparatus is programmed to periodically transfer data to a central database server. The central database server can collect and store data from CPAP apparatus for a number of patients who undergo sleep therapy. A user can access the central database server over the internet to obtain information. Each user is given access only to information for his or her patients. The user may provide data to the central database server for transmission to the CPAP apparatus during a subsequent connection that the CPAP apparatus makes to the central database server.

Abstract: A nasal mask for use in respiratory therapy is provided with one or more vent ports which are adjustable for directing vented air in a direction which is most comfortable to the patient. By providing adjustable vent ports, the patient can adjust the direction of the vented air to a position that best accommodates the patient. Each vent port can be in the form of a passage in a member which is mounted to rotate in an opening through the mask. The member may be rotated in the opening to change the direction of air flowing through the passage or passages. The member may be designed to rotate about a fixed axis relative to the mask, or it may be spherical and designed to rotate in any direction. Preferably, a knob or tab is provided for grasping to facilitate manually adjusting the vent port orientation.

Abstract: An improved aerosol chamber for an ultrasonic nebulizer which prevents relatively large medicament droplets from being inhaled by a patient. The chamber has a housing formed from a polycarbonate resin and is generally cylindrically shaped with a spherical top surface. The chamber includes an air inlet formed in the top surface and an aerosol outlet formed in a side surface. A centrally located mist tube extends coaxial from the air intake downwardly past the aerosol outlet. A longitudinally extending slot is formed in the mist tube facing the side surface of the housing diametrically opposite the outlet. The slot extends from a lower edge of the tube upwardly toward the air intake. A geyser baffle is disposed at an angle within the mist tube above the slot to deflect larger droplets away from the slot. The baffle includes an upper edge spaced from an adjacent inner surface of the mist tube to define a relatively small gap to allow inlet air to flow through the mist tube.
