The When aggregate is coupled to a breathing apparatus, a substantially volume neutral delivery of anesthetic agent is provided a to the breathing apparatus. | 02-09-2012 |
20150040900 | VAPORIZER ARRANGEMENT FOR A BREATHING APPARATUS - 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. | 02-12-2015 |
