Abstract:
An electrically conductive plastic (ECP) material can be used to heat water in a reservoir of a respiratory humidifier to encourage heating and/or humidification of gases passing through the respiratory humidifier. The electrically conductive plastic material can at least in part overmould the base and/or walls of the chamber and/or the reservoir of the respiratory humidifier. The reservoir can also partially or fully be formed from the electrically conductive plastic material.
Abstract:
Heater modules (12) are configured for streamlined daisy chain connectivity that includes front end and intermediate daisy chain power injection devices (14), water resistant heater assemblies (20, 32, 34), and shielding (210). A power injection device (14) is configured with connectivity for insertion of power into heater modules (12) that are in front and intermediate daisy chain positions while enabling data communications between heater modules (12) positioned on opposite sides of the power injection locations.
Abstract:
The invention relates to a radiant heater (1) comprising a heating tube element (2). The heating tube element (2) has a heating tube (3) that is permeable to infra-red radiation, or is transparent or semi-transparent. The heating tube (3) is located in a focus area of a reflector having at least one focussing curvature (4). The at least one heating tube element (2) is located in a housing (6) comprising at least one front face (7) that is transparent or semi-transparent to infra-red radiation. The housing (6) has an edge face and a rear face (8, 9) that shield against infra-red radiation. The at least one heating tube element (2) has a plurality of carbon fibres (10) inside the heating tube (3), said fibres forming a dimensionally stable infra-red heating spiral (11) of carbon cord (12) and the reflector is an infra-red reflector (5) adapted to the infra-red spectrum of the heating tube element (2).
Abstract:
It is disclosed a radiant heating device comprising: a bearing structure (2), carrying at least one holding chamber (6); at least one lamp (8) having at least two terminals (11) for electric connection housed in the holding chamber (6), and a radiant portion (8a) extending externally of the holding chamber (6) along a geometric extension axis (X). At least one elastic support element (15) is in engagement with the bearing structure (2) and sealingly fitted around said lamp (8) for elastically coupling said lamp (8) to the bearing structure (2) and closing said holding chamber (6). The electric-connection terminals (11) are mutually spaced apart by an amount (D) smaller than the linear extension of the radiant portion (8a) of the lamp (8), to be detected along said geometric extension axis (X).
