The present invention relates to an "facility!" ? .only sterile keeping of onerations. ^i; Let by filtering the air from a person inside.

Until now, face masks were generally used in Russian a textlien Gev / ebe or made of peeipnet rr ^ rared parry or carton. These brands act as mechanical filters are on the one hand vrepen the occurring V'ö.rr'eentv.'icklunr bothersome for the person wearing them and, on the other hand, have the disadvantage that the person's breath is still weppeblat.en directly from their mouth to the front.

An improvement in the situation was already achieved when one went over to the actual operating theater to separate an air curtain from the rest of the operating room. A further advance was made through never introduction achieved by covering the entire facial space, transparent face masks, the interior of which Masks by means of a flexible line to a central

the Fi ^. 1 a complete invention, sren "RKe facility and the Fir. 2 shows a section through the air suction device.

Non-inventive equipment for keeping sterile Operating rooms essentially consist of three elements,

rr 'with a face mask 1 covering the firm face space of the person stepping on it, one on the back of the same person to be bcfeLiLireridfcn Lurtririaaur ^ orrichtunr 2 and ni; r. one or two of the suction device 2 with the man): ο 1 suction hoses 3

The face mask 1 is made of a transparent plastic and is reformed in such a way that it fits snugly against the head of the person wearing it without, of course, being uncomfortably tight. It completely closes off the face of the person. A plastic hose 3, which rests against the lower inner edge of the mask and has a slot 3a there, is used as flexible suction lines, through which the person's exhaled air is sucked into it. Fresh air inlet openings la, which are arranged on the upper edge of the mask and are provided with valve flaps, are used to supply fresh air into the interior of the mask, so that fresh air can be released into the mask, but no exhaust air to it. Four can exit into the Unpebunr.

The usual means are used to hold the mask v; earth, v; although it is not necessary, an exact seal is given To reach Kerf des Träf-ers, because of the when draining The slight negative pressure created by the breathing air prevents the breathing air from escaping.

The two ends of the tube 3 open into the upper part of the air intake device 2 shown in FIG. 2 in Länpsschnitt, v / oak means zv / eggs hook 2a for example, of a set on the shoulders of the person and with a hip belt 4a fixed supporting belt h at Back of the person concerned is attached.

The air intake device 2 is essentially designed as a bottle-like vessel 5 made of plastic, in FIG

The vessel 5 weeps on an intermediate base 5b, so that a cavity remains between this and the actual vessel base to accommodate the power source 7, which is designed as batteries or accumulators. The latter is via lines not shown and one in the fir. 1 shown switch 7a with the motor 6a of the vent ".

This filter 8 forms a self-contained one Unit of approximately cylindrical shape and is inserted in the correspondingly shaped blow-out opening 10 of the vessel 5 in such a way that it can be easily exchanged. Depending on the type of filter used, the type of attachment may vary * In the present case, due to its simplicity, it is an elastic press fit.

The advantages of the device according to the invention are evident. The respiratory air of the person concerned can no longer flow directly away from the mouth, but is immediately after the exit diverted from the respiratory organs in the simplest way to the person's back and filtered there. It will but the freedom of movement of the person, in contrast to the known facilities of this type, so to speak not at all restricted. Setup is easy, simple and practical
