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 often cause odor nuisance for 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 are connected directly under the covers to eliminate the odor.

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 covers can be a hypothermia for the patient 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 having severe skin burns or injuries Hautver.

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

In der Zeichnung ist dargestellt: In the drawing is shown:

Abb. A Fig. A

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

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

mit ( 3 ) eine Ansaugpatrone, als Schalldämpfer und Chemisorptionsfilter ausgebildet; formed with (3) a Ansaugpatrone as a silencer and chemical sorption filter;

mit ( 4 ) der Ventilator; with (4) of 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 muffler and Chemi sorption.

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. Muffler, at the same time serve as a purification cartridge and may be equipped with additional UV lamps, according to the invention include alternately arranged acidic and alkaline compositions having a germicidal and odor effect.

Es wird weiterhin vorgeschlagen, Patronen auswechsel bar auf der Saug- und Druckseite des Ventilators im Saug- und/oder Gegenstrom zu betreiben, dh 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 further proposed cartridge replaceable bar on the suction and pressure side of the fan in the suction and / or counter-current to operate, ie that the auszuwechselnde cartridge on the suction side by a partly loaded cartridge is replaced from the pressure side and on the pressure side of a new cartridge is used, so that a high deposition of the odor carrier is secured in this way always.

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 Ansaugpatronen are preferably inserted into one another and include multi-layer alkaline and acidic compositions, which are used as sorption application, wherein the final layer is preferably a neutral activated carbon layer.

In der Abb. B ist dargestellt: . In Figure B is shown:

mit ( 1 ) ein perforiertes Ansaugrohr, das gleichzeitig als Schalldämpfer ausgebildet ist; with (1) a perforated suction pipe, which is formed simultaneously as a silencer;

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

mit ( 4 ) steckbare, schalldämpfende Rohre mit integrierter Filterpatrone ( 5 ). plug, sound absorbing pipes with an integrated filter cartridge (4) (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 filtering capacity depending on the number of beds and space size can be arbitrarily changed.
