Device for gasifying liquid and for metering the gas thereby obtained

Apparatus for delivery predetermined dosages of anesthetic gases are disclosed, including a reservoir for supply of anesthetic liquid, gasification chamber, a riser for delivering anesthetic liquid from the reservoir to the gasification chamber which is maintained at a predetermined temperature at which the anesthetic liquid is converted directly into anesthetic gas, a gas supply for maintaining the anesthetic liquid under a predetermined gas pressure which substantially corresponds to the pressure at which the anesthetic liquid is delivered to the gasification chamber, and a delivery line for controllably delivery the anesthetic gas from the gasification chamber.

Device for gasification and dosage

Anesthesia and/or respirator apparatus is disclosed which includes a moistening and/or gasification chamber. The chamber is constructed such that liquid intended to be gasified or evaporated can be received from a source through a metering valve. In the preferred embodiment, the gasification chamber includes a heatable plate or the like for the heating of the supplied liquid. The apparatus means further includes a microprocessor for measuring the energy which is used for the gasification as a measure of the quantity of liquid supplied. In this regard, if certain defined functions are not fulfilled, an alarm signal is generated.
