VAPORIZER ARRANGEMENT FOR A BREATHING APPARATUS

摘要

A vaporizer arrangement for a breathing apparatus serves the double purpose of vaporizer and pressurized supply of vapor-containing gas for direct delivery to a patient. The vaporizer arrangement has at least a first gas inlet channel for conveying a flow of a carrier gas into a vaporization chamber, a vaporizer for vaporizing a liquid into the carrier gas in the vaporization chamber, and a gas outlet channel for conveying a flow of vapor-containing carrier gas out of the vaporization chamber and toward the patient. The vaporizer arrangement further has a gas flow regulator that maintains the carrier gas within the vaporization chamber at an overpressure, and that controls the flow of vapor-containing carrier gas out of the vaporization chamber in a variable manner.

1. A vaporizer arrangement for a breathing apparatus (1), comprising:
at least a first gas inlet channel that conveys a flow of a carrier gas into a vaporization chamber (9); a vaporizer that vaporizes a liquid into the carrier gas in the vaporization chamber; a gas outlet channel that conveys a flow of vapor-containing carrier gas out of the vaporization chamber and toward a patient; and a gas flow regulator configured to maintain the carrier gas within the vaporization chamber at an overpressure, and to control a flow of said vapor-containing carrier gas out of the vaporization chamber in a variable manner.
