发明名称 Method for reuse of anaesthetics and a device for realization of the method.
摘要 The invention relates to a method and to a device for carrying out the method. The method is based on the anaesthetic agent not absorbed by a patient being adsorbed in a filter during exhalation and thereafter being desorbed from the filter upon inhalation and being introduced once again into the respiratory flow, this flow passing through a carbon dioxide absorber before it is supplied to the patient. The device comprises a common conduit for the supply and removal of anaesthetic gases and respiratory gases to and from a patient. Arranged in this conduit is an adsorption filter for adsorption and desorption of anaesthetic gases. In order to obtain a device of this type which by simple means prevents the carbon dioxide adsorbed from the exhalation gas of the patient in the adsorption material from being supplied to the patient in the next inhalation phase, the invention proposes that the common conduit (2) between the patient (3) and the adsorption filter (4) should be divided at least in part into an inhalation branch (6) and an exhalation branch (7), a carbon dioxide absorber (8) being arranged in the inhalation branch (6). <IMAGE>
