Abstract

The invention relates to a breathing mask for long-term positive pressure respiration of patients with pulmonary insufficiency. The breathing mask surrounds mouth and nose. In long-term respiration (about 8 hours a day) sealing of the breathing mask against the face presents problems: the mask must only rest against the face very lightly in order to avoid painful pressure sores; on the other hand, however, it may only have low losses due to leakage. This sealing problem is solved by an inflatable annular bead which is formed such that the particularly sensitive areas of the face, that is bridge of the nose and eyes, are left free. Sealing and tolerability of the breathing mask can be improved by controlling the internal pressure in the sealing bead, so that the air pressure in the bead is slightly higher on inspiration than the air pressure in the mask, while it is lower on expiration, by a special cross-sectional shape of the bead with sealing lips and by application of an intermediate layer of a skin-compatible material.

Description

Die Erfindung bezieht sich auf eine dicht schließende Gesichtsmaske, die zur Langzeit-Überdruck-Beatmung von Personen mit Lungeninsuffizienz eingesetzt wird.The invention relates to a tight-fitting Facial mask used for long-term positive pressure ventilation People with lung insufficiency is used.

Die Beatmungsmaske (1) umschließt Mund und Nase. Die Atemluft wird der Maske von einem Drucklufterzeu­ ger (2) ("Beatmungsgerät") durch Schlauchleitungen und ein Dreiweg-Umschaltventil (3) ("Beatmungsventil") zugeführt. Dadurch wird im Innenraum der Maske ein Überdruck aufgebaut, der ausreichend hoch ist, um, ohne Zutun des Benutzers, dessen Lunge mit Atemluft zu füllen.The respiratory mask ( 1 ) encloses the mouth and nose. The breathing air is supplied to the mask from a compressed air generator ( 2 ) ("respirator") through hose lines and a three-way switch valve ( 3 ) ("respirator valve"). As a result, an excess pressure is built up in the interior of the mask, which is sufficiently high to fill the lungs with breathing air without the user having to do anything.

Beim Ausatmen wird die verbrauchte Luft durch das Beatmungsventil ausgeblasen (Fig. 1, Fig. 2).When exhaling, the used air is blown out through the ventilation valve ( Fig. 1, Fig. 2).

Bei der Langzeitbeatmung wird die Maske täglich mehr als 8 Std. getragen.With long-term ventilation, the mask increases daily worn as 8 hours.

Bei diesem Betrieb ist die Abdichtung des Beatmungs­ maske zum Gesicht problematisch:In this operation, the ventilation is sealed problematic face mask:

  • - einerseits darf die Maske nur sehr leicht anliegen, um Druckstellen und Beschädigungen der Epidermis zu vermeiden.- on the one hand, the mask may only fit very lightly, around pressure points and damage to the epidermis avoid.
  • - andererseits darf sie aber auch nur geringe Leckver­ luste aufweisen.- On the other hand, it may only have a small leakage have cracks.

Vergleichbare Beatmungsmasken sind bis heute nur zur Kurzzeit-Beatmung bekannt, z. B. zur Notbeatmung von Unfallopfern.To date, comparable ventilation masks are only for Short-term ventilation is known, e.g. B. for emergency ventilation of Accident victims.

Die Abdichtung dieser Beatmungsmasken zum Gesicht erfolgt z. T. durch einen aufblasbaren, geschlossenen Ringwulst, wobei die Luftmenge im Wulst während der Beatmung konstant bleibt (z. B. "Taschenmaske" der Fa. Lärdal Medical D 8031 Gräfelfing, Teilekatalog, Ausg. Jan. 86).These ventilation masks are sealed off from the face e.g. T. by an inflatable, closed ring bead, the amount of air in the bead during ventilation remains constant (eg "pocket mask" from Lärdal Medical D 8031 Graefelfing, parts catalog, edition Jan. 86).

Zum Teil erfolgt die Abdichtung auch durch Dichtlippen, die sich unter dem Innendruck ans Gesicht anlegen (z. B. "Silikonmaske" der Fa. Lärdal Medical, w. o.).In some cases, sealing is also carried out using sealing lips, that press against the face under the internal pressure (For example "Lärdal Medical" silicone mask, see above).

Diese Beatmungsmasken sind zur Langzeit-Beatmung nicht geeignet:These ventilation masks are for long-term ventilation not suitable:

  • - entweder verläuft das Dichtungselement quer über den Nasenrücken und führt dort wegen der lokal erhöhten Druckbelastung, insbesondere bei Patienten mit einem "hohen" Nasenrücken, zu Hautreizungen mit schmerzhaften Druckstellen;- either the sealing element runs transversely over the bridge of the nose and leads there because of the locally increased pressure load, especially at Patients with a "high" bridge of the nose, too Skin irritation with painful pressure points;
  • - oder die Beatmungsmaske ist im Nasen-Augen- Bereich so bereit, daß der Augapfel belastet und/oder das Gesichtsfeld eingeschränkt wird.- or the respiratory mask is in the nose and eye - Area so ready that the eyeball is stressed and / or the visual field is restricted.

Zudem bestehen bei diesem Beatmungsmasken die Dicht­ elemente aus Luft- und Wasserundurchlässigem Material und liegen direkt an der Gesichtshaut an.In addition, there are seals on this ventilation mask elements made of air and water impermeable material and lie directly on the skin of the face.

Dadurch kann in diesem Bereich die Hautfeuchtigkeit nicht verdunsten. Da nasse Haut wesentlich empfindlicher gegenüber Dauerbeanspruchungen ist, wird die Gefahr von Beschädigungen der Epidermis noch vergrößert.As a result, the skin moisture cannot in this area evaporate. Because wet skin is much more sensitive against permanent stresses, the risk of Damage to the epidermis increased.

Die Erfindung hat sich die Aufgabe gestellt, eine Beatmungs­ maske zu schaffen, die ausreichende Dichtigkeit aufweist und auch bei fortgesetztem Dauerbetrieb zu keinen körperlichen Beeinträchtigungen des Benutzers führt.The invention has set itself the task of ventilation to create a mask that has sufficient tightness and no physical activity even with continued continuous operation Leads to impairments of the user.

Das beschriebene Abdichtungsproblem wird erfindungsgemäß durch ein aufblasbaren Ringwulst (4) aus luftdichtem, elastischem Material mit einer Formgebung nach Anspruch 1 gelöst. Dabei werden der Nasenrücken und die Augäpfel frei gehalten (Fig. 3, Fig. 4, Fig. 5).The sealing problem described is solved according to the invention by an inflatable annular bead ( 4 ) made of airtight, elastic material with a shape according to claim 1. The bridge of the nose and the eyeballs are kept free ( Fig. 3, Fig. 4, Fig. 5).

An der Nase liegt die Dichtung nur in der oberen Hälfte der Nasenseitenwände an, darunter auf der Wange neben den Nasenflügeln.The seal on the nose is only in the upper half of the nose sidewalls, including on the cheek next to the Nostrils.

Eine konkave Wölbung des Dichtungswulstes, mit einem Krümmungsradius unter 1 cm, wie sie sonst entsteht, wenn der Dichtungswulst über den Nasenrücken verläuft und dort zu hohen lokalen Drücken führt, wird auf diese Art vermieden.A concave curvature of the sealing bead, with a Radius of curvature less than 1 cm, as is otherwise the case when the sealing bead runs over the bridge of the nose and there leads to high local pressures avoided this kind.

Zudem wird ein ausreichendes Gesichtsfeld für den Benutzer gewährleistet.In addition, a sufficient field of vision for the User guaranteed.

Durch die Anforderung einer Dichtlippe (8) entsprechend Anspruch 2 kann der zusätzliche Dichtungseffekt einer sich unter dem Innendruck selbst anlegenden Dichtlippe zur Verbesserung der Abdichtung dienen (Fig. 6).By requesting a sealing lip ( 8 ) according to claim 2, the additional sealing effect of a self-applying sealing lip under the internal pressure can serve to improve the seal ( FIG. 6).

Das Querschnittsprofil des Ringwulstes kann entsprechend Anspruch 3 geformt werden (Fig. 7).The cross-sectional profile of the annular bead can be shaped according to claim 3 ( Fig. 7).

Wird jetzt der Ringwulst mit Luft gefüllt, dann wird der Ringwulst immer mehr einen kreisförmigen Querschnitt annehmen. Dabei wird die Dichtlippe immer weiter vom Masken­ körper weg in Richtung der Gesichtsoberfläche gedreht. Die Kante der Dichtkippe bewegt sich dabei um den Be­ trag "H" (Fig. 8).If the ring bead is now filled with air, the ring bead will increasingly take on a circular cross section. The sealing lip is turned further and further away from the mask body in the direction of the face surface. The edge of the sealing tip moves around the loading "H" ( Fig. 8).

Dieser Effekt begünstigt eine gute Anpassung der Beatmungsmaske auch an stark unterschiedliche Gesichts­ formen.This effect favors a good adaptation of the Ventilation mask also on very different faces to form.

Durch die Steuerung des Innendruckes im Ringwulst ent­ sprechend Anspruch 4 kann die Druckbelastung, die der Ringwulst auf das Gesicht ausübt, auf das notwendige Mindestmaß verringert werden. Zusätzlich ergibt sich beim Ausatmen eine starke Reduzierung des Anpreßdruckes, was einen Erholungsvorgang in den betroffenen Haut­ partien begünstigen kann, z. B. durch eine bessere Durchblutung während der Entlastungsphase. By controlling the internal pressure in the toroid speaking claim 4, the pressure load that the Ring bead on the face, on the necessary Minimum be reduced. In addition there is when exhaling a strong reduction of the contact pressure, what a recovery process in the affected skin can favor lots, e.g. B. by a better one Blood flow during the relief phase.  

Die Steuerung des Innendruckes im Ringwulst kann durch eine Anordnung entsprechend Anspruch 5 erfolgen (Fig. 10). Diese Anordnung hat den Vorteil, daß der Betrag des Druck­ unterschiedes zwischen dem Druck im Wulst und dem Druck in der Maske in einem gewissen Ausmaß verstellbar ist. Nachteilig wirkt sich dabei aber aus, daß durch die zu­ sätzliche Drosselstelle (10) in der Zuluftleitung dem Be­ atmungsgerät eine höhere Leistung abgefordert wird.The control of the internal pressure in the ring bead can be done by an arrangement according to claim 5 ( Fig. 10). This arrangement has the advantage that the amount of pressure difference between the pressure in the bead and the pressure in the mask is adjustable to a certain extent. A disadvantage is that the additional throttle point ( 10 ) in the supply air line requires a higher performance from the breathing apparatus.

Bei einer Anordnung entsprechend Anspruch 6 wird das Beatmungsgerät nicht zusätzlich beansprucht (Fig. 11). Dies ist besonders bei Batteriebetrieb wichtig. Dafür ist eine Einstellmöglichkeit nicht vorhanden.In an arrangement according to claim 6, the ventilator is not additionally claimed ( Fig. 11). This is particularly important for battery operation. There is no setting option for this.

Durch eine hautfreundliche Zwischenlage (11) entsprechend Anspruch 7 wird die Bildung eines Feuchtigkeitsfilmes zwischen Gesichtshaut und Atemmaske vermieden (Fig. 5 und Fig. 12).By a skin-friendly liner (11) according to claim 7, the formation of a moisture film between facial skin and breathing mask is avoided (FIG. 5 and FIG. 12).

Aufgabe der Zwischenlage ist es, die ausgeschiedene Hautfeuchtigkeit aufzusaugen und durch Kapillarwirkung zum Außen- oder Innenraum der Maske zu transportierten, wo sie verdunsten kann.The job of the liner is to remove the one Absorb skin moisture and by capillary action to be transported to the outside or inside of the mask, where it can evaporate.

Dadurch wird die Haut in der belasteten Zone trocken gehalten, wodurch sich ihre Widerstandsfähigkeit erhöht. Zudem ist eine derartige Zwischenlage preisgünstig herstellbar und leicht zu befestigen, z. B. durch Knöpfe. Sie kann also haufig ausgewechselt werden, was besonders bei Dauerbetrieb aus hygienischen Gründen empfehlenswert ist.This will dry the skin in the affected area held, which increases their resilience. In addition, such an intermediate layer is inexpensive producible and easy to attach, e.g. B. by Buttons. So it can be replaced frequently, which is especially hygienic for continuous operation Reasons is recommended.

Bei einer Ausbildung des Dichtungselementes ent­ sprechend Anspruch 8 kann der Ringwulst und ggf. seine Drucksteuerung wegfallen, was die Beatmungsmaske vereinfacht (Fig. 9).In a design of the sealing element accordingly claim 8, the ring bead and possibly its pressure control can be omitted, which simplifies the respiratory mask ( Fig. 9).

Die Befestigung der Membran (13) kann durch einen Drahtspannring (17) erfolgen. Dies setzt voraus, daß am Außenrand der Maske eine Nut vorgesehen ist, in die der Drahtspannring eingelegt wird, und daß zusätzlich die Außenkontur der Maske in jedem Bereich konvex ist, damit der Drahtspann­ ring an jedem Punkt anliegt.The membrane ( 13 ) can be fastened by means of a wire tension ring ( 17 ). This requires that a groove is provided on the outer edge of the mask, into which the wire tension ring is inserted, and that in addition the outer contour of the mask is convex in each area, so that the wire tension ring rests at every point.

Durch Anbringung des Beatmungsventils (3) direkt an der Beatmungsmaske entsprechend Anspruch 9 (Fig. 12) werden 2 Vorteile erzielt:By attaching the ventilation valve ( 3 ) directly to the ventilation mask according to claim 9 ( Fig. 12), two advantages are achieved:

  • 1. Durch den Fortfall eines Verbindungsstückes zwi­ schen Beatmungsventil und Beatmungsmaske, das länger als 2 cm ist, wird das Totvolumen in der Maske verringert. (Unter "Totvolumen" ist das Volu­ men der verbrauchten Luft zu verstehen, die nach dem Ausatmen noch in der Maske verbleibt.) Dadurch wird die Beatmungsqualität der Maske verbessert. 1. By the elimination of a connecting piece between ventilation valve and respiratory mask, the is longer than 2 cm, the dead volume in the mask decreased. (Under "dead volume" is the volume to understand the amount of used air that remains in the mask after exhaling.) This improves the ventilation quality of the mask improved.  
  • 2. Bei einer Ausführung der Beatmungsmaske ent­ sprechend Anspruch 7 kann der Strömungswider­ stand des Beatmungsventils für die Drucker­ höhung im Ringwulst herangezogen werden, ohne daß eine zusätzliche Schlauchleitung erforder­ lich ist.2. When executing the respiratory mask speaking claim 7, the flow resistance the ventilation valve for the printer be raised in the ring bead without that an additional hose line is required is.

Durch eine Fixierung der Atemmaske am Gebiß des Benutzers mit Hilfe eines Formstückes (15) entsprechend Anspruch 10 (Fig. 13) wird ein Verrutschen der Beatmungsmaske, z. B. durch Kopfbewegungen, verhindert und ein stets gleich­ bleibender Sitz der Maske gewährleistet. Dadurch verbessert sich die Abdichtung der Beatmungsmaske.By fixing the breathing mask on the user's teeth with the help of a fitting ( 15 ) according to claim 10 ( Fig. 13), slipping of the respiratory mask, z. B. prevented by head movements and ensures a constant fit of the mask. This improves the sealing of the ventilation mask.
