Abstract
A portable anaesthetic machine allows dispensing of a liquid anaesthetic to a patient, which is sometimes desirable and may be hard to achieve, especially with portable equipment. This portable anaesthetic machine has a gas flow generator for generating a flow of gas at an adjustable pressure and/or flow rate, an inspiratory line and an expiratory line. The gas flow generator, inspiratory line and expiratory line constitute the gas flow pathways for the respirator. A membrane is arranged in the gas flow pathways, made of a self-sealing material. The membrane can be punctured by a syringe needle for dispensing the liquid anaesthetic into the gas flow pathways an optional number of times.
