Abstract
Description
Die Erfindung betrifft eine Innenmaske für eine Atemschutzmaske mit verbessertem Sitz und Tragekomfort.The invention relates to an inner mask for a respirator with an improved Fit and comfort.
Bei Atemschutzmasken mit Innenmaske kann der Sitz der Innenmaske bedingt durch eine unterschiedliche Gesichtsform zu weit vom Gesicht des Maskenträgers entfernt sein. Es besteht aber auch die Möglichkeit, daß die Innenmaske unangenehm am Ge sicht des Maskenträgers sitzt. Ursache dafür ist, daß es insbesondere im Nasenbereich des Maskenträgers zu einem erhöhtem Druck der Dichtlinie der Innenmaske auf das Gesicht des Maskenträgers kommt, was zu einer erheblichen Beeinträchtigung des Tragekomforts führt.In the case of breathing masks with an inner mask, the fit of the inner mask can be caused by a different face shape too far from the face of the mask wearer be. But there is also the possibility that the inner mask on the Ge view of the mask wearer. The reason for this is that it is particularly in the nose area of the mask wearer to an increased pressure of the sealing line of the inner mask on the Face of the mask wearer comes, which significantly affects the Comfort.
Aus der DD-PS 1 60 727 ist ein Anschlußstück für eine Atemschutzvollmaske bekannt, bei dem zur Anpassung an unterschiedliche Gesichtsformen zwischen Innen- und Au ßenmaske unterschiedliche Aufknöpfmöglichkeiten der Innenmaske auf dem erfin dungsgemäßen Anschlußstück bestehen. Die drei verschiedenen Möglichkeiten der Aufknöpfung der Innenmaske an die Atemschutzmaske ermöglichen eine bessere Abdichtung im Bereich der Mund- und Nasenpartie des Maskenträgers. Nachteilig an dieser Lösung ist, daß nur drei Möglichkeiten der Anpassung bestehen, daß Einstell aufwand erforderlich ist, und daß keine Entkoppelung zwischen Innen- und Außen maske besteht.From DD-PS 1 60 727 a connector for a full face mask is known, where to adapt to different face shapes between inside and outside Different masking options for the inner mask on the inventor appropriate connector exist. The three different ways of Buttoning the inner mask onto the respirator allows a better one Sealing in the area of the mouth and nose area of the mask wearer. Disadvantageous this solution is that there are only three ways to adjust that setting effort is required, and that no decoupling between inside and outside mask exists.
Eine weitere Möglichkeit zur Erhöhung der Sicherheit des Trägers einer Atemschutz maske ist aus der US-PS 4,905,683 bekannt. Die Lösung bietet die Möglichkeit zur Detektierung der Leckage am Außendichtrahmen der Vollmaske. Nachteil dieser Lö sung ist, daß diese kostenaufwendige Atemschutzmaske nicht an unterschiedliche Ge sichtsformen anpaßbar ist.Another way to increase the safety of the wearer of respiratory protection mask is known from US Pat. No. 4,905,683. The solution offers the possibility of Detection of leakage on the outer sealing frame of the full face mask. Disadvantage of this Lö solution is that this costly respirator mask does not have different Ge view forms is customizable.
Am Markt sind auch offene Innenmasken für Atemschutzmasken bekannt, die ohne formschlüssige Verbindung zur Dichtlinie des äußeren Maskenkörpers im Kinnta schenbereich ausgeführt sind. Open inner masks for breathing masks are also known on the market, but without positive connection to the sealing line of the outer mask body in the chin area are executed.
Nachteilig an diesen Lösungen ist, daß bei der Anpassung an unterschiedliche Ge sichtsformen durch die offene Ausführung der Dichtsitz nicht gegeben ist.The disadvantage of these solutions is that when adapting to different Ge views through the open design of the sealing seat is not given.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Innenmaske für eine Atemschutzmaske zu entwickeln, die sich an unterschiedliche Gesichtsformen anpaßt, wodurch eine besserer Dichtsitz erzielt wird und sich der Tragekomfort für den Masken träger erhöht.The present invention has for its object an inner mask for a To develop a respirator that adapts to different face shapes, which results in a better seal and the wearing comfort for the masks carrier increased.
Erfindungsgemäß wurde die Aufgabe dadurch gelöst, daß eine Innenmaske für eine Atemschutzmaske entwickelt wurde, die über flexible Ausgleichselemente verfügt, die symmetrisch vom Rand bis in den Nasenbereich der Innenmaske durchgehend ange ordnet sind. Bestand bei den Lösungen des Standes der Technik die Möglichkeit der Anpassung an eine Gesichtsform durch begrenzte Einstellung, die Verformung des oberen Innenmaskenbereiches oder durch eine offene Ausführung der Innenmaske, so wurde mit der erfindungsgemäßen Lösung ein bessere Anpassung einer geschlossen ausgeführten Innenmaske durch eine Entkoppelung zwischen dem oberhalb der Aus gleichselemente angeordneten Teil der Innenmaske und dem unterhalb der Aus gleichselemente angeordneten und mit der Außenmaske verbundenen Teil der Innen maske erzielt, indem die bei der Anpassung notwendige Verformung der Innenmaske auf definierte Verformungsbereiche begrenzt wird. Beim Aufsetzen der Atemschutz maske drückt sich die Innenmaske durch die erfindungsgemäßen flexiblen Aus gleichselemente mit relativ gleichbleibendem Anpreßdruck angenehm an die jeweilige Gesichtsform des Maskenträgers dicht an, ohne daß sich die außerhalb der Aus gleichselemente angeordneten Innenmaskenbereiche verformen. Das bedeutet, daß bei der Anpassung an den Maskenträger die Geometrie des oberen Bereiches der In nenmaske erhalten bleibt.According to the invention the object was achieved in that an inner mask for a Respiratory mask was developed, which has flexible compensation elements that symmetrical from the edge to the nose area of the inner mask are arranged. Was there a possibility in the state of the art solutions Adaptation to a face shape through limited adjustment, the deformation of the upper inner mask area or by an open design of the inner mask, see above a better adaptation of a was concluded with the solution according to the invention executed inner mask by a decoupling between the above the off the same elements arranged part of the inner mask and the below the Aus same elements arranged and connected to the outer mask part of the interior mask achieved by the necessary deformation of the inner mask is limited to defined deformation ranges. When putting on the respiratory protection mask expresses the inner mask by the flexible Aus according to the invention same elements with relatively constant contact pressure pleasant to the respective Face shape of the mask wearer close, without the outside of the deform the same elements arranged inner mask areas. It means that when adapting to the mask carrier, the geometry of the upper area of the In remains intact.
Durch die Beschränkung der Verformung auf die definierten Bereiche der flexiblen Ausgleichselemente wird der Tragekomfort erhöht, da eine Behinderung des Masken trägers, z. B. durch erhöhtem Druck der Dichtlinie auf den Nasenbereich des Masken trägers oder eine Einengung durch undefinierte Verformung der Innenmaske vermie den wird. By restricting the deformation to the defined areas of the flexible Compensating elements increase the wearing comfort because the mask is obstructed carrier, e.g. B. by increased pressure of the sealing line on the nose area of the mask wearer or a narrowing due to undefined deformation of the inner mask that will.
Die flexiblen Ausgleichselemente sind erfindungsgemäß so angeordnet, daß sie - aus gehend von den Enden, die im Wangenbereich des hinteren Randes der Innenmaske angeordnet sind - nach vorn in Richtung des Verbindungsstückes für den Anschluß an die Atemschutzmaske und vor dem Verbindungsstück nach oben in den Nasenbereich verlaufen. Die Flexibilität der Ausgleichselemente wird dadurch erreicht, daß sie einen u- oder v-förmigen Querschnitt aufweisen. Zur Erhöhung der Flexibilität kann die Wandstärke der Ausgleichselemente dünnwandiger als die der Innenmaskenwände ausgeführt sein. Die flexiblen Ausgleichselemente können im Wangenbereich an den Enden offen oder geschlossen ausgeführt sein.The flexible compensating elements are arranged according to the invention so that they - from going from the ends to the cheek area of the back edge of the inner mask are arranged - forward towards the connector for connection the respirator and in front of the connector up into the nose area run. The flexibility of the compensating elements is achieved in that they are one have a u-shaped or v-shaped cross-section. To increase flexibility, the Wall thickness of the compensation elements is thinner than that of the inner mask walls be executed. The flexible compensating elements can be attached to the cheek area The ends are open or closed.
