Abstract

In order to overcome the so-called nausea threshold in the mouth-to-mouth method which is instantly required in unconscious patients and in order to avoid the mutual infection with contagious diseases by the patient receiving the breath and by the donor, the tube comprises an attachment and a mouthpiece. The bent attachment which keeps the tongue at the back in the mouth of the injured individual and hence keeps the trachea free, has an anatomically shaped cover plate which seals the mouth of the recipient of the breath, and a standardised cone on the donor side. A hydrophobic filter is firmly incorporated in the adaptable mouthpiece by ultrasonic welding. This filter keeps back both blood and saliva on both sides while the breathing air can flow through unhindered throughout the mouth-to-mouth breathing.

Description

Die Erfindung bezieht sich auf einen Tubus, der für die Not­ fall-Beatmung von Bewußtlosen konzipiert worden ist. Bewußtlose, z.B. in Folge von Unfällen, sind häufig nur durch sofortige Mund-zu-Mund-Beatmung zu retten. Obgleich die Tech­ nik dieser Notfall-Beatmung in den Erste-Hilfe-Kursen vermit­ telt wird, scheitert ihre Anwendung häufig zum einen an der sog. Ekelschwelle, die Hilfswillige nicht zu überwinden ver­ mögen, zum anderen an der Furcht, sich durch aus dem Mund blu­ tende Verletzte oder Kontakt mit deren Speichel zu infizieren (Aids, Hepatitis, TB). Die gleiche Ansteckungsgefahr besteht für den Verletzten durch mit der Atemluft des Spenders über­ tragenen Speichel oder Blut.The invention relates to a tube for emergency case ventilation has been designed by the unconscious. Unconscious, e.g. as a result of accidents, are often just through save immediate mouth-to-mouth resuscitation. Although the Tech nik of this emergency ventilation in the first aid courses is used, their application often fails because of the So-called disgust threshold, the willingness to help not overcome like, on the other hand, fear of bleeding out of your mouth infecting injured persons or contact with their saliva (AIDS, hepatitis, TB). The same risk of infection exists for the injured person through with the donor's breath carried saliva or blood.

Versucht wird, dem mit verschiedenartigen Beatmungshilfen zu begegnen, u.a. durch die Verwendung von Beatmungs-Tuben. Mit einem Tubus, der, wie der hier verwendete, über einen ge­ bogenen Ansatz verfügt, der im Mund des Bewußtlosen die Zunge zurück- und damit die Luftröhre freihält, der mit einer ana­ tomisch geformten Abdeckplatte versehen ist, die den Mund des Atemempfängers abdeckt und damit ein nutzloses Entweichen der Atemluft des Spenders verhindert und der schließlich auf der Spenderseite über einen Normkonus sowie ein adaptierbares Mundstück verfügt, werden zwar die Ekelschwelle überwunden, erhebliche Nachteile anderer Beatmungshilfen beseitigt und die Gefahr der gegenseitigen Ansteckung vermindert.Attempts are being made with various ventilation aids encounter, among other things through the use of ventilation tubes. With a tube that, like the one used here, has a ge curved approach, the tongue in the mouth of the unconscious back and thus keeps the windpipe clear, which with an ana tomically shaped cover plate is provided, which covers the mouth of the Respirator covers and thus a useless escape of the Breathing air from the donor is prevented and ultimately on the Dispenser side via a standard cone as well as an adaptable one Mouthpiece, the disgust threshold is overcome, significant disadvantages of other ventilation aids and the The risk of mutual infection is reduced.

Nicht sichergestellt ist indessen, daß bei der Beatmung Blut und Speichel des Verletzten in den Mund des Spenders oder Blut und Speichel des Spenders mit der Atemluft in den Mund des Ver­ letzten gelangt mit der Gefahr der Übertragung von Krankheits­ erregern.However, there is no guarantee that blood will form during ventilation and saliva of the injured person in the donor's mouth or blood and saliva of the donor with the air we breathe into the mouth of the ver last comes with the risk of transmission of disease excite.

Bekannt ist der Einbau von Einweg-Ventilen in Beatmungs-Tuben, die jedoch nur einseitig verhindern, daß Blut und Speichel des Verletzten unmittelbar in den Mund des Spenders gelangen kön­ nen, nicht aber umgekehrt.It is known to install one-way valves in ventilation tubes, which, however, only prevent the blood and saliva of the Injured can get directly into the donor's mouth nen, but not the other way around.

Der Erfindung liegt die Aufgabe zu Grunde, unter gleichzeiti­ ger Nutzung der bereits beschriebenen Vorzüge des verwendeten Beatmungs-Tubus durch eine in der Herstellung einfache Vor­ richtung, die die Beatmung durch hohe Durchlässigkeit nicht erschwert, zu erreichen, daß für die Dauer der Mund-zu-Mund- Beatmung sichergestellt wird, daß Blut und Speichel in bei­ den Richtungen gleichermaßen zurückgehalten werden. Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß in das adaptierbare Mundstück des Beatmungs-Tubus ein hydropho­ ber Filter mit einem Durchmesser von 28 mm in Ultraschall- Schweißtechnik fest eingearbeitet wird, der beidseitig Blut und Speichel für eine Dauer von mindestens fünf Minuten bei einem Atemdruck Δ p von maximal fünf mbar und einer rela­ tiven Luftfeuchte von 100% sicher zurückhält.The invention is based, with simultaneous use of the advantages of the ventilation tube used by a simple to manufacture device that does not make ventilation difficult due to high permeability, to achieve that for the duration of the mouth-closing -Mouth ventilation ensures that blood and saliva are retained in the directions equally. This goal is achieved in that in the adaptable mouthpiece of the ventilation tube a hydrophobic filter with a diameter of 28 mm in ultrasonic welding technology is firmly incorporated, the blood and saliva on both sides for a period of at least five minutes at a breathing pressure Δ p of a maximum of five mbar and a relative humidity of 100%.

Ein Ausführungsbeispiel ist im Längsschnitt zeichnerisch dar­ gestellt und wird nachfolgend beschrieben.An embodiment is shown in the drawing in longitudinal section and is described below.

Der Tubus besteht aus dem gebogenen Ansatz (Ziffer 1), der in den Mund des Bewußtlosen geschoben wird sowie dem adaptier­ baren Mundstück (Ziffer 2).The tube consists of the curved attachment (number 1 ), which is pushed into the mouth of the unconscious and the adaptable mouthpiece (number 2 ).

Er verfügt auf der Empfängerseite über eine anatomisch geform­ te Abdeckplatte (Ziffer 3) sowie einen 15 mm Normkonus für den Anschluß sowohl des Mundstücks als auch handelsüblicher Beat­ mungsbeutel.On the receiver side, it has an anatomically shaped cover plate (number 3 ) and a 15 mm standard cone for connecting both the mouthpiece and standard ventilation bag.

In das Mundstück ist in Ultraschall-Schweißtechnik fest einge­ arbeitet ein hydrophober Filter mit einem Durchmesser von 28 mm (Ziffer 5).A hydrophobic filter with a diameter of 28 mm is worked into the mouthpiece using ultrasonic welding technology (section 5 ).
