Description

Dichtungs- und Begrenzungseinrichtung für IJber- und Unterdruckkammern Dichtungs- und Begrenzungseinrichtungen für Xber- und Unterdruckkammern, bestehend aus einem vorzugsweise zylindrischen Gehäuse und einem in demselben angeordneten ringförmigen, aufblasbaren Gummikissen, sind bekannt. Bei derartigen Dichtungs- und Begrenzungseinrichtungen hat sich der Nachteil ergeben, daß, wenn der Innendurchmesser des aufblasbaren Gummikissens kleiner wird als die stirnseitigen Begrenzungswandungen des Gehäuses, das Kissen aus dem Gehäuse herausquillt und unter Umständen sogar reißt. Man hat diesen über stand dadurch zu beseitigen versucht, daß man Stirnwandungen unterschiedlichen Innendurchmessers auf Vorrat hielt und die Stirnwandungen mit für den jeweiligen Anwendungsfall passendem Innendurchmesser einsetzte. Das Auswechseln der Stirnwandungen ist sehr umständlich.Sealing and limiting device for hyperbaric and negative pressure chambers Sealing and limiting devices for high and low pressure chambers, consisting of from a preferably cylindrical housing and one arranged in the same annular, inflatable rubber cushions are known. With such sealing and limiting devices has the disadvantage that when the inner diameter of the inflatable rubber cushion becomes smaller than the frontal boundary walls the housing, the cushion oozes out of the housing and possibly even rips. One has tried to eliminate this over stood by the fact that one end walls different inside diameters in stock and the end walls with it suitable inside diameter for the respective application. The replacement the end walls is very cumbersome.

Die Erfindung verhindert das Herausquellen des aufgepumpten Luftkissens dadurch, daß an beiden Stirnseiten des Gehäuses auf den gewünschten Durchmesser stufenlos einstellbare, an sich bekannte Lamellenblenden vorgesehen sind. The invention prevents the inflated air cushion from swelling out in that on both ends of the housing to the desired diameter Infinitely adjustable, per se known lamellar panels are provided.

Zwar sind auch bei (tber- und Unterdruckkammern Lamellenblenden an sich schon bekannt, diese dienen aber nicht zur Verhinderung des Herausquellens eines aufblasbaren Luftkissens, sondern bilden selbst das Mittel zur Abdichtung der Kammern nach außen bzw. das Mittel zum Andrücken einer Dichtungsmanschette an den zu behandelnden Körperteil. It is true that lamellar diaphragms are also on in (overpressure and underpressure chambers already known, but these are not used to prevent it from oozing out an inflatable air cushion, but form the means of sealing themselves the chambers to the outside or the means for pressing a sealing sleeve on the part of the body to be treated.

Im Erfindungsfalle fällt den Lamellenblenden somit eine völlig verschiedene Aufgabe zu. In the case of the invention, the lamellae diaphragms are therefore completely different Task to.

Die Zeichnung erläutert die Erfindung schematisch an einem Ausführungsbeispiel. The drawing explains the invention schematically using an exemplary embodiment.

An den offenen Stirnseiten 3 und 4 einer vorzugsweise zylindrischen Kammer 1, in welcher sich ein ringförmiges, aufblasbares Gummikissen (nicht gezeichnet) befindet, ist je eine Lamellenblende 8 angeordnet. Die Durchmesser dieser Lamellenblenden sind durch Getriebe 5, 6, 7 stufenlos veränderlich. Hierdurch wird es ermöglicht, den lichten Durchmesser der durch die Lamellenblenden gebildeten Stirnseiten der Kammer dem Innendurchmesser des aufgepumpten Kissens stufenlos so anzupassen, daß ein Herausquellen des Kissens mit Sicherheit verhindert wird. At the open end faces 3 and 4 a preferably cylindrical Chamber 1, in which there is a ring-shaped, inflatable rubber cushion (not shown) is located, a lamella diaphragm 8 is arranged. The diameter of these lamellas are continuously variable by gears 5, 6, 7. This enables the clear diameter of the end faces formed by the lamellar diaphragms Chamber to adapt steplessly to the inner diameter of the inflated cushion so that the cushion is prevented from swelling out with certainty.

An einer der beiden Stirnflächen sind ein pneumatischer Wulst 9, 10, 11 und ein an einem aufgeschraubten Ring 2 befestigter Bajonettverschluß 12 für den luft- und druckdichten Anschluß der Einrichtung an beliebige andere Geräte vorgesehen. On one of the two end faces are a pneumatic bead 9, 10, 11 and a bayonet catch 12 fastened to a screwed-on ring 2 for the airtight and pressure-tight connection of the device to any other device is provided.
