Abstract

It is known that bed-ridden patients are a frequent source of nuisance to the environment due to unpleasant odours. There have already been proposed devices which are directly connected under the bed cover in order to eliminate the unpleasant odours. However, continuous aspiration under the bed cover may lead to hypothermia of the patient, so that it must be rejected in many cases. In order to avoid these disadvantages the invention proposes an air-purifying device which comprises a purification cartridge (3) on the suction side of a fan (4) and a purification cartridge (5) on the pressure side of the fan (4). The purification cartridges (3, 5) are designed as combined sound absorbers/chemisorption filters. The filter cartridge (3) is preferably designed as a multi-layer chemisorption filter, the layers comprising alkaline and acidic compositions having bactericidal and odour-absorbing effects. <IMAGE>

Description

Es ist bekannt, daß bettlägerige Patienten vielfach Geruchsbelästigungen für die Umwelt verursachen.It is known that bedridden patients are common Cause odor nuisance to the environment.

Es wird vielfach vorgeschlagen, Geräte zu bauen, die unmittelbar unter der Bettdecke angeschlossen werden, um die Geruchsbelästigungen zu beseitigen.It is often proposed to build devices that connected directly under the duvet, to eliminate the smell.

Die ständige Absaugung unter der Bettdecke kann eine Unterkühlung für den Patienten bedeuten und muß daher in vielen Fällen abgelehnt werden.The constant suction under the duvet can Hypothermia for the patient means and must therefore be rejected in many cases.

Dies gilt insbesondere für stark geschwächte Patienten und solche, die starke Hautverbrennungen oder Hautver­ letzungen aufweisen.This is especially true for severely debilitated patients and those who have severe skin burns or skin ver have recent.

Um eine Frischluftatmosphäre für den Patienten und andere Personen im Raum zu schaffen, wird erfindungs­ gemäß vorgeschlagen, eine Vorrichtung entsprechend Zeichnung zu verwenden.To create a fresh air atmosphere for the patient and Creating other people in the room becomes inventive proposed according to a device accordingly To use drawing.

In der Zeichnung ist dargestellt:The drawing shows:

Abb. A Fig.A

mit (1) ein Pflegebett;with ( 1 ) a nursing bed;

mit (2) die Luftzirkulation;with ( 2 ) air circulation;

mit (3) eine Ansaugpatrone, als Schalldämpfer und Chemisorptionsfilter ausgebildet;with ( 3 ) a suction cartridge, designed as a silencer and chemisorption filter;

mit (4) der Ventilator;with ( 4 ) the fan;

mit (5) die Reinigungspatrone auf der Druckseite, die ebenfalls als Schalldämpfer und Chemi­ sorptionsfilter ausgebildet ist.with ( 5 ) the cleaning cartridge on the pressure side, which is also designed as a silencer and chemi sorption filter.

Schalldämpfer, die gleichzeitig als Reinigungspatronen dienen und mit zusätzlichen UV-Strahlern ausgerüstet sein können, beinhalten erfindungsgemäß abwechselnd angeordnete saure und alkalische Massen, die eine keimtötende und geruchsabsorbierende Wirkung haben.Mufflers that also act as cleaning cartridges serve and equipped with additional UV lamps according to the invention include alternately arranged acidic and alkaline masses, the one  have germicidal and odor-absorbing effects.

Es wird weiterhin vorgeschlagen, Patronen auswechsel­ bar auf der Saug- und Druckseite des Ventilators im Saug- und/oder Gegenstrom zu betreiben, d. h. daß die auszuwechselnde Patrone auf der Ansaugseite durch eine teilbeladene Patrone von der Druckseite ersetzt wird und auf der Druckseite eine neue Patrone eingesetzt wird, so daß auf diese Weise stets eine hohe Abscheidung der Geruchsträger gesichert ist.It is also suggested to replace cartridges bar on the suction and pressure side of the fan To operate suction and / or counterflow, d. H. that the cartridge to be replaced on the suction side by a partially loaded cartridge is replaced from the pressure side and inserted a new cartridge on the print side is, so that always a high separation in this way the smell carrier is secured.

Die Ansaugpatronen sind vorzugsweise ineinandersteckbar und beinhalten mehrschichtige alkalische und saure Massen, die als Sorptionsschichten Anwendung finden, wobei die Endschicht vorzugsweise eine neutrale A-Kohle-Schicht ist.The suction cartridges are preferably pluggable and include multilayered alkaline and acidic Masses that are used as sorption layers, the final layer preferably being a neutral one A coal layer is.

In der Abb. B ist dargestellt: Fig. B shows:

mit (1) ein perforiertes Ansaugrohr, das gleichzeitig als Schalldämpfer ausgebildet ist; with ( 1 ) a perforated intake pipe, which is also designed as a silencer;

mit (2) die Chemisorptionsfilterpatrone mit dem Ventilator (3);with ( 2 ) the chemisorption filter cartridge with the fan ( 3 );

mit (4) steckbare, schalldämpfende Rohre mit integrierter Filterpatrone (5).with ( 4 ) pluggable, sound-absorbing pipes with integrated filter cartridge ( 5 ).

Auf diese Weise ist gesichert, daß die Chemisorptions­ filterkapazität je nach Bettenanzahl und Raumgröße beliebig verändert werden kann.In this way it is ensured that the chemisorption filter capacity depending on the number of beds and room size can be changed at will.
