Abstract

Appts. for the disposal of air exhaled by patients connected to anaesthetic machines, which is exhausted to a central point, includes plant for sepg. the N2O fraction. - The air is passed through a pipe with a controllable closing mechanism and bubbled in limited amts. through a finely porous layer into closed vessel no.1, partly filled with water kept at 0 deg.C, where it is absorbed physically in amts. of 1.3052 vol. pts. N2O/vol. pt. water at 0 deg.C; or in water kept at higher temps. suitable for the required deg. of absorption e.g. 25 deg.C, at which the physical absorption is 0.5962 vol. pts. N2O/vol. pt. water. The air freed from N2O is collected in the space above the water level and can be discharged to the outside atmos. through an outlet with controllable closure mechanism. When the water is satd. with N2O, the contaminated air supply is switched to a similar vessel no.2. The water from vessel no.1 is transferred to vessel no.3, where it is heated, so that N2O is expelled and collects above the water level. The N2O is then transferred to (a) appts. where it decomposed into the elements by heating to min. 600 deg.C; or (b) appts. for the recovery of N2O. After emptying, each vessel is filled with water at the required temp. A soln. for chemical reaction with N2O can be used instead of water.

Description

Die Erfindung stellt eine Entsorgungsmöglichkeit dar, die die ausgeatmete N2O-haltige Luft eines am Narkosegerät angeschlos­ senen Patienten auffängt und zentral ableitet, nach den Ober­ begriff des Anspruchs 1.The invention represents a disposal option that collects and centrally discharges the exhaled N 2 O-containing air from a patient connected to the anesthesia machine, according to the preamble of claim 1.

Die zentrale Absaugung und Ableitung der N2O-haltigen Aus­ atmungsluft ist in gut eingerichteten Krankenhäusern zum Schutz des OP-Personals bereits bestehende Praxis, wird aber unbehan­ delt an die Außenluft abgegeben.The central extraction and discharge of the N 2 O-containing exhaled air is already an existing practice in well-equipped hospitals to protect the operating room staff, but is released untreated to the outside air.

Sinn dieser Erfindung ist es, die mit N2O angereicherte und zentral abgeleitete Ausatmungsluft über eine Anlage zur Ent­ sorgung des N2O-Anteils zu leiten.The purpose of this invention is to pass the centrally exhaled air enriched with N 2 O through a system for disposing of the N 2 O portion.

Der Vorteil dieser Erfindung liegt darin, daß das in der Aus­ atmungsluft befindliche N2O, bekannt als ein klimawirksames Gas - entnommen aus der Druckschrift "HOECHST HEUTE" Nr. 96, Seite 11 letzter Absatz, Seite 12 erster Absatz und aus einem Artikel der "HANNOVERSCHEN LAND- und FORSTWIRTSCHAFTLICHEN ZEITUNG" vom 3.6.1989 - nicht mehr unbehandelt an die Außen­ luft freigesetzt wird und damit den Anteil der klimawirksamen Gase reduziert und der Treibhauseffekt gemindert wird.The advantage of this invention is that the N 2 O in the breathing air, known as a climate-effective gas - taken from the publication "HOECHST HEUTE" No. 96, page 11 last paragraph, page 12 first paragraph and an article from "HANNOVERSCHE LAND- und FORSTWIRTSCHAFTLICHE ZEITUNG" from 3.6.1989 - is no longer released untreated to the outside air, thus reducing the proportion of climate-affecting gases and reducing the greenhouse effect.

Die Absorbtion des in der Ausatmungsluft befindlichen N2O erfolgt mit physikalischen und chemischen Reaktionen, die im einzelnen in den Schutzansprüchen dargelegt sind.The absorption of the N 2 O in the exhaled air takes place with physical and chemical reactions, which are set out in detail in the protection claims.
