PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet eine Vorrichtung zum Athmen in mit Rauch oder schädlichen Gasen erfüllten Räumen unter Verwendung von verdichtetem Sauerstoff bezw. verdichteter Luft. Dieselbe unterscheidet sich von den bereits bekannten Vorrichtungen ähnlicher Art dadurch, dafs in ihr die lebendige Kraft des verdichteten Sauerstoffs dazu benutzt wird, einen beständigen Kreislauf der ganzen Luftmenge in der Athmungsvorrichtung zu bewirken,, während bei den älteren Vorrichtungen dieser Kreislauf durch die Ein- und Ausathmung selbst hervorgerufen werden mufste, wodurch das Athmen in mehr oder minder hohem Grade erschwert wurde.The subject of the invention forms a device for breathing in with smoke or harmful gases filled spaces using compressed oxygen BEZW. compressed air. It differs more similarly from the devices already known Kind by the fact that in it the living force of the compressed oxygen is used for this purpose is to bring about a constant circulation of the whole amount of air in the breathing device, while in the older devices this cycle through inhalation and exhalation itself had to be evoked, whereby the breathing in a more or less high degree Degree was made more difficult.
Bei der vorliegenden Vorrichtung ist hinter dem Luftreiniger in das Luftzuführungsrohr eine Düse eingeschaltet, vermittelst deren durch den verdichteten Sauerstoff die ausgeathmete Luft durch den in bekannter Weise angeordneten Luftreiniger hindurchgesaugt und die gereinigte und mit frischem Sauerstoff gemischte Luft dem Munde wieder zugeführt wird.In the present device is behind the air cleaner in the air supply pipe When a nozzle is switched on, it mediates the exhaled one through the compressed oxygen Air is sucked through the air cleaner arranged in a known manner and the cleaned and air mixed with fresh oxygen is returned to the mouth.
Eine nach diesem Erfindungsgedanken ausgeführte Athmungsvorrichtung ist in Fig. 1 der Zeichnung dargestellt; Fig. 2 zeigt in gröfserem Mafsstabe einen Schnitt durch die Saugdüse.A breathing device designed according to this inventive concept is shown in FIG Drawing shown; Fig. 2 shows on a larger scale a section through the suction nozzle.
Der Vorrath an hochgespanntem Sauerstoff befindet sich in der Flasche a. Durch das Druckverminderungsventil b und eine Rohroder Schlauchleitung gelangt der Sauerstoffstrom zum Kanal c, welcher so klein bemessen ist, dafs der Vorrath in der Flasche die beabsichtigte Zeit hindurch mil gleicher Stärke ausströmt. Die auszusaugenden Athmungsgase können die Mündung des Druckkanals umstreichen. Der aus c ausströmende Sauerstoffstrom erfafst diese Gase und treibt sie in den Kanal d, welcher zu dem Kanal c in einem solchen Querschnittsverhältnifs steht, dafs die Gase mit einem gewissen Druck durch das Verbindungsrohr c in den Athmungsraum i geworfen werden.The supply of high-tension oxygen is in bottle a. The oxygen flow passes through the pressure reducing valve b and a pipe or hose line to channel c, which is so small that the supply in the bottle flows out for the intended time with the same strength. The respiratory gases to be sucked out can sweep around the mouth of the pressure channel. The stream of oxygen flowing out of c captures these gases and drives them into channel d, which has such a cross-sectional ratio to channel c that the gases are thrown at a certain pressure through the connecting tube c into the breathing space i.
Im Rohre f wird eine Saugwirkung hervorgerufen. Da das Rohr_/ mit dem Luftreiniger g und dieser wieder durch die Rohre h und e mit dem Athmungsraum i in Verbindung steht, so werden die der Auffrischung bedürftigen Athmungsgase durch diese Einrichtung stets von Neuem durch den Luftreiniger g gesaugt, wobei nach und nach eine Bereicherung der Athmungsluft an Sauerstoff — bis zu 60 pCt. — entsteht.A suction effect is created in the pipe f. Since the pipe / is connected to the air purifier g and the air purifier again through the pipes h and e to the breathing space i, the breathing gases that need to be refreshed are always sucked anew through the air purifier g by this device, whereby an enrichment step by step the breathing air to oxygen - up to 60 pCt. - arises.
