Abstract

The two-aperture nozzle allows percutaneous artificial respiration of a patient, combining the two principles of jet-ejector respiration and venturi. The nozzle can comprise a tube 4mm. diameter x 70mm. long, allowing air to penetrate into the trachea, and a tube of 1.6mm. diameter inside one tube, and emerging from it at 40mm. from its end, where it is connected at a supply of high-pressure air. The end of the nozzle can be cut at 45 degrees, so that the two tubes can be welded at the same end.

Description

DESCRIPTION
La canule permet de ventile-r artificiellement avec de t'oxy- gène (pression hyperbarrique et atmo-sphérique) ou de l'air comprimé toute personne présentant une insuffisance ou un
arrêt respiratoire.DESCRIPTION
The cannula allows to ventilate-r artificially with oxygen (hyperbaric and atmospheric pressure) or compressed air anyone with insufficiency or
respiratory arrest.

Dans le cas d'une insuffisance ou d'un arrêt respiratoire, les tecniques habituelles sont:
. l'intubation trachéale
. la trachéotomie
. la "jet-ventilation
Le nouveau système proposé permet de ventiler le sujet par
la voie per-cutanée. II n'exige pas l'intervention d'un per
sonne spécialisé.In the case of insufficiency or respiratory arrest, the usual techniques are:
. tracheal intubation
. tracheostomy
. the "jet-ventilation
The new system proposed allows the subject to be broken down by
the per-cutaneous way. It does not require the intervention of a per
sounds specialized.

il réuni t les deux principes:
. la "jet-ventilation't
. le principe Venturi
et agit selon le "va-et-vient". it combines the two principles:
. the "jet-ventilation't
. the Venturi principle
and acts according to the "back and forth".

C'est une canule en acier inoxydable à deux lumières, compo
sée de:
. un tube A de diamètre 4mm, de longueur 70mm, coudévà 130
pour faciliter le passage de la canule dans la trachée.It is a two-lumen stainless steel cannula, consisting of
set of:
. a tube A diameter 4mm, length 70mm, bends to 130
to facilitate the passage of the cannula in the trachea.

. un tube (aiguille G14) de 1,6 mm de diamètre. IL est si
tué à l'intérieur du tube A et ressort du tube A à 40 mm de 'l'entrée. II est relié en C au système "jet-ventillation".. a tube (needle G14) 1.6 mm in diameter. He is so
killed inside tube A and comes out of tube A 40 mm from the entrance. It is connected at C to the "jet-ventilation" system.

Dans chaque tube -se trouve un mandrin pour préserver cha
que lumière de la canule lors de l'entrée de celle-ci dans la
trachée.In each tube is a mandrel to preserve each
that light from the cannula when entering it into the
trachea.

La canule est coupée à son extrémité D sous un angle de 450 de façon que les deux tubes soient soudés au même point extrème. ç
Le système fonctionne selon le principe du "va-et-vient":
. te gaz oxygène ou air comprimé) entre de façon intermit
tente par le tube B avec une pression de 3-32 barres, dans
la trachée (principe de la 'fjet-vent-ilation")
. dans le même t e p5, le tube A envoie de l'air atmosphéri
que dans la trachée de façon intermittente (principe Ventur
C'est la phase aspiration. Quand celle-ci est finie commen
ce le cycle de l'expiration passive par le tube A.The cannula is cut at its end D at an angle of 450 so that the two tubes are welded at the same end point. vs
The system works on the back-and-forth principle:
. oxygen gas or compressed air) intermittently
tent by tube B with a pressure of 3-32 bars, in
the trachea (principle of 'fjet-vent-ilation ")
. in the same te p5, tube A sends atmospheric air
intermittently in the trachea (Ventur principle
This is the aspiration phase. When this one is finished starts
this the cycle of passive exhalation through tube A.

Les deux tubes oeuvent etre branchés sur n'importe quel sys
tème d'aspiration ou d'expiration.The two tubes can be connected to any sys
suction or expiration tem.

Avantages
Ce système ne nécessite pas une infrastructure lourde car
il peut etre branché sur un système léger, portatif.Benefits
This system does not require a heavy infrastructure because
it can be connected to a light, portable system.

Sa manipulation est facile à acquérir.  Its handling is easy to acquire.

C'est pourquoi; il peut être utilisé dans toutes les situations réclamant une e intervention urgente: accidents de la route,
du travail, tremblements de terre, guerre......etc, mais
aussi à l'hopital, en particulier dans le service d'otorhinolaryngologie. That is why; it can be used in all situations requiring urgent intervention: road accidents,
of work, earthquakes, war ...... etc, but
also in the hospital, especially in the otolaryngology department.
