Abstract
A device for controlling the breathing gas flow is provided including a breathing gas block (2), a cover (4) and a valve plate (3) as well as a heating device. Condensation effects are prevented from occurring with the supply of the smallest possible amount of energy by provision of a heating foil (16) as a heating element.
Claims22
A device for controlling the breathing gas flow, the device comprising:
- a breathing gas block;
- a cover, said block and said cover cooperating to enclose a breathing gas space;
- and
- a heating device for heating the breathing gas space, the heating device including a heating foil provided as a heating element;
- a valve plate arranged at a location between said breathing gas block and said cover, said heating foil being arranged at said valve plate.
A breathing gas low control system comprising:
- a breathing gas block with breathing gas connections;
- a cover, said block and said cover cooperating to enclose breathing gas channels;
- a valve part arranged at a location between said breathing gas block and said cover;
- and
- a heating device for heating one or more of breathing gas channels, the heating device including a heating foil arranged on said valve part.
A method of providing a breathing gas flow control device, the method comprising:
- forming a breathing gas block with breathing gas spaces and breathing gas connections;
- connecting a valve plate to the block;
- positioning a heating foil as a heating element adjacent to one or more of the breathing gas spaces;
- and
- placing a cover over the block, the block and the cover cooperating to enclose the spaces as breathing gas conduits with the heating foil disposed adjacent to one or more of the conduits;
- positioning the heating foil on the valve plate.
A method of providing a breathing gas flow control device, the method comprising:
- forming a breathing gas block with the breathing gas spaces and breathing gas connections;
- connecting a valve plate to the block;
- positioning a heating foil as a heating element adjacent to one or more of the breathing gas spaces;
- and
- placing a cover over the block, the block and the cover cooperating to enclose the spaces as breathing gas conduits with the heating foil disposed adjacent to one or more of the conduits;
- determining condensate portions of the breathing spaces where condensate occurs;
- determining non-condensate portions of the breathing spaces which are free from condensate;
- applying the heating foil to the condensate portions;
- causing the non-condensate portions to be free of the heating foil.
A breathing gas flow control system, comprising:
- a breathing gas block with breathing gas connections;
- a cover, said block and said cover cooperating to enclose breathing channels;
- a valve arranged at a location between said breathing gas block and said cover;
- and
- a heating device for heating one or more of breathing gas channels, the heating device including a heating foil provided as a heating element adjacent to one or more of the breathing gas channels;
- said breathing gas channels have condensate portions where condensate occurs;
- said breathing gas channels have non-condensate portions which are free from condensate;
- said heating foil is arranged on said condensate portions;
- said non-condensate portions are free of the heating foil.
