"Elastischer Beutel zur Luft- oder Sauerstoffzuführung bei Wiederbelebungsapparaten" . ■"Elastic bag for air or oxygen supply for resuscitation apparatus ". ■
Die Erfindung bezieht sich auf einen elastischen Beutel zur Luft- oder Sauerstoffzuführung bei Wiederbelebungsapparaten, der quer zu seiner Längsachse elastisch zusammendrückbar ist. Nach dem Zusammendrücken nimmt der Beutel infolge seiner Elastizität seine ursprüngliche Form an, wobei er Luft bzw. Sauerstoff einsaugt, die bzw. der beim nachfolgenden Zusammendrücken des Beutels in die Atmungsorgane des Patienten gepresst wird.The invention relates to an elastic bag for Air or oxygen supply in resuscitation apparatus, which is elastically compressible transversely to its longitudinal axis. After being squeezed, the bag increases as a result of it Elasticity returns to its original shape, sucking in air or oxygen during the subsequent compression of the bag is pressed into the patient's respiratory system.
Da derartige Beutel im nicht zusammengedrückten Zustand relativ grosse Abmessungen aufweisen, nehmen sie sehr viel Platz ein, der in der Bestecktasche eines Arztes meistens nicht zur Verfügung steht. Es bestand deshalb die Aufgabe, diesen Beuteln eine solche !Form zu geben, dass sie einmal die notwendige Luftmenge aufnehmen können, zum anderen aber so zusammenlegbar sind, dass sie im unbenutzten Zustand möglichst wenig Platz einnehmen.Since such bags have relatively large dimensions when not compressed, they take up a lot of space, which is usually not available in a doctor's cutlery pocket stands. It was therefore the task to give these bags such a shape that they once had the necessary shape Can absorb air volume, but on the other hand so collapsible that they take up as little space as possible when not in use.
Es sind zu dem gena nnten Zweck blasebalgartige Beutel bekannt geworden, die aus einer luftdichten Hülle aus faltbarem StoffBellows-type bags are known for the purpose mentioned made from an airtight envelope made of foldable fabric

bestehen und ein Ein- und ein Auslaßventil aufweisen. Innerhalb der Hülle ist ein federndes Element vorgesehen, das die Hülle in Bereitschaftsstellung bringt. Dieses federnde Element wird aus einem in Windungen längs der Innenwand verlegten, aufblasbaren Schlauch gebildet. Nach dem Herauslassen der Luft aus dem Federschlauch kann dieser Beutel zusammengelegt, gerollt oder gefaltet werden. Ein anderes Balggebläse dieser Art ist dahingehend abgewandelt, dass zwei zueinander konzentrische Hüllen vorgesehen sind, die durch Abstandstege miteinander verbunden sind.exist and have an inlet and an outlet valve. Within the shell is provided a resilient element that the Bringing the case into readiness position. This resilient element is made from an inflatable one laid in turns along the inner wall Hose formed. After letting the air out of the spring tube, this bag can be folded up or rolled up or be folded. Another bellows fan of this type is modified so that two concentric to each other Sheaths are provided which are connected to one another by spacer bars.
Diese Balggebläse können zwar zusammengelegt werden, jedoch ist eine solche Ausbildung aufwendig und damit teuer, da im Inneren der äusseren Hülle eine weitere Hülle oder ein Schlauch vorgesehen sein muß. Ausserdem können diese Balggebläse nicht sofort benutzt werden, es muß vielmehr erst der Schlauch bzw. der Zwischenraum zwischen innerer und äusserer Hülle aufgeblasen werden, wodurch wert volle Zeit vertan wird, die für die Rettung des Patienten von grösster Bedeutung sein kann. Auch besteht die Gefahr von Undichtigkeiten am Schlauch oder an dem zusätzlich erforderlichen Ventil. Schließlich sind der Schlauoh bzw. die innere Hülle zusätzliche Elemente, die zusätzlichen Raum beanspruchen. Diese Balggebläse sind zwar zusammenlegbar, beanspruchen aber immer noch relativ viel Raum.Although these bellows fans can be folded up, such a design is complex and therefore expensive, since a further cover or a hose must be provided inside the outer cover. In addition, these bellows blowers cannot be used immediately, rather the tube or the space between the inner and outer cover must first be inflated, which wastes valuable time, which can be of great importance for saving the patient. There is also the risk of leaks in the hose or in the additionally required valve. After all, the smart or the inner shell are additional elements that take up additional space. This B a lggebläse are indeed folded, but still take considerable space.

Die Lösung dieser Aufgabe erfolgt gemäß, de τ Erfindung dadurch, daß der Beutel wenigstens zwei elastisehe, ringförmige Abschnitt e aufweist, die unte rs ehie d-Iiehe Wandstärken haben und/oder über verdünnte Zonen miteinander verbunden sind. Der erfindungsgemässe zusammengeklappte Beutel nimmt einen relativ kleinen Baum ein, der einem Bruchteil seines ursprünglichen Volumens entspricht, so daß er raumsparend aufbewahrt werden kann.Medical test; UKCteriZttbiiingen Bind. The solution of this object is achieved in accordance with, de τ invention in that the bag at least two elastisehe having annular portion e, the unte rs Ehie d-Iiehe have wall thicknesses and / or are connected via thinned zones. The folded bag according to the invention occupies a relatively small tree, which corresponds to a fraction of its original volume, so that it can be stored in a space-saving manner.
Der erfindungsgemässe Beutel kann aus einem mittleren, in axialer Richtung nicht zusammenklappbaren Teil und zwei äusseren, in den mittleren Teil hineinklappbaren Teilen bestehen, wobei die beiden äusseren Teile sich vom mittleren Teil nach den äusseren Enden verjüngend ausgebildet sind. Dadurch wird das Zusammenklappen erleichtert. Wenn in weiterer Ausgestaltung der Erfindung die beiden äusseren Teile sich auf den gesamten . Umfang erstreckende Einschnürungen aufweisen, wird der Vorteil erreicht, daß sich der zusammengeklappte Beutel in diesem zusammengeklappten Zustand selbst hält und nicht ohne weiteres aufgeklappt werden kann. Begünstigt wird dies noch dadurch,, daß nach einem weiteren Merkmal der Erfindung zwischen bzw. neben den Einschnürungen die äusseren Teile verdickt ausgebildet sind. Es muß eine bestimmte Zügkraft aufgewendet werden, um die durch die Verdickungen bedingten Rückhaltekräfte zu überwinden und den Beutel aufzuklappen.The bag according to the invention can consist of a middle, in the axial direction non-collapsible part and two outer parts, which can be folded into the central part, the two outer parts tapering from the middle part to the outer ends. This will making it easier to fold. If in further development the invention, the two outer parts on the whole . Have circumferentially extending constrictions, the advantage is achieved that the collapsed bag in this When folded, it holds itself and cannot be opened easily. This is further favored by that according to a further feature of the invention between or next to the constrictions, the outer parts are thickened are. A certain pulling force must be used to to overcome the retention forces caused by the thickenings and open the bag.

Wird der Beutel 1 gemäß Figur 1 in axialer Richtung zusammengedrückt t dann knioken die äueseren Seile 3 und 4 an den Einschnürungen 6,7 und 8,9 ein. Die ringförmigen Wandteile 16, werden um die Kanten 18,19 um nahezu T80° nach innen in den mittleren Teil 2 gebogen, während die ringförmigen Wandteile 20,21 ihre ursprüngliche Lage zur Mittelachse des rotationssymmetrisch ausgebildeten Beutels 1 behalten. Ebenfalls erfolgt eine Abbiegung der ringförmigen^Wandteile 22,23 um die Einschnürungen 7 und 9 um nahezu 180°. Bei diesen Abbiegungen wird nach Überschreitung eines Totpunktes eine Schnappbewegung'erzielt. Gleichzeitig wird den abgebogenen Wandte.ilen 16, 1^V 22, 23 eine Vorspannung verliehen, duroh die die zusammengeklappten äusseren Beutelteile 3 und 4 in ihrer Lage innerhalb des mittleren Beutelteiles 2 mit Sicherheit gehalten werden. Ea ist eine gewisse Kraft notwendig, um die Vorspannungen der abgebogenen Wandteile 16, 17, 22, 23 und die Totpunkte beim Zurückbiegen zu überwinden, um wieder den betriebsbereiten Zustand des Beutels 1 herzustellen.When the bag 1 is compressed in accordance with Figure 1 in the axial direction, then t knioken äueseren the ropes 3 and 4 at the constrictions 6.7 and 8.9 a. The annular wall parts 16 are bent inwards by almost T80 ° around the edges 18, 19 into the central part 2, while the annular wall parts 20, 21 retain their original position relative to the central axis of the rotationally symmetrical bag 1. The annular wall parts 22, 23 are also bent around the constrictions 7 and 9 by almost 180 °. With these turns, a snap movement is achieved after a dead center has been exceeded. At the same time, the bent wall parts 16, 1 ^ V 22, 23 are given a pretension, duroh the folded outer bag parts 3 and 4 are held in their position within the middle bag part 2 with certainty. Ea a certain force is necessary in order to overcome the pretension of the bent wall parts 16, 17, 22, 23 and the dead points when bending back in order to restore the operational state of the bag 1.
Die Einschnürungen 6 bis 9 können auch sickenförmlg vertieft oder erhaben ausgebildet sein. Hierbei kann der Beutel 1 eine gleichbleibende Wandstärke aufweisen.The constrictions 6 to 9 can also be deepened in the form of a bead or be raised. Here, the bag 1 can have a constant wall thickness.
