Description
La présente invention concerne un tube endo-trachéal ou un tube trachéotomique à ballon pour anesthésie, notamment pour le traitement au laser de tissus pathologiques des voies respiratoires hautes.The present invention relates to an endotracheal tube or a tracheotomy balloon tube for anesthesia, in particular for the laser treatment of pathological tissues of the upper respiratory tract.
On connait déjà un tube endo-trachéal pour anesthésie comportant un corps tubulaire servant à véhiculer le gaz de ventilation et d'anesthésie et pourvu au voisinage de son extrémité distale d'un ballon susceptible d'être gonflé depuis l'extérieur, par l'intermédiaire d'un canal auxiliaire, de manière à assurer l'étanchéité avec la trachée et à permettre ainsi une ventilation efficace. Un tel tube, ainsi que son ballon gonflable,est constitué de matières organiques naturelles ou de synthèse, afin de présenter une souplesse suffisante pour ne pas traumatiser les voies respiratoires dans lesquelles il est introduit.There is already known an endotracheal tube for anesthesia comprising a tubular body used to convey the ventilation and anesthesia gas and provided in the vicinity of its distal end with a balloon capable of being inflated from the outside, by the through an auxiliary channel, so as to seal with the trachea and thus allow efficient ventilation. Such a tube, as well as its inflatable balloon, is made of natural or synthetic organic materials, in order to present sufficient flexibility so as not to traumatize the respiratory tracts into which it is introduced.
Ce tube endo-trachéal connu donne toute satisfaction dans le cas d'une intervention classique. Toutefois, dans le cas d'un traitement au laser, qui présente des avantages certains par rapport aux techniques opératoires traditionnelles, des difficultés apparaissent.This known endotracheal tube gives complete satisfaction in the case of a conventional intervention. However, in the case of a laser treatment, which has certain advantages over traditional operating techniques, difficulties appear.
En effet, la matière constitutive d'un tel tube endo-trachéal connu absorbe généralement bien l'énergie infrarouge,de sorte que si une anesthésie est délivrée par ce tube pendant une intervention au moyen d'un laser, on risque la détérioration, et même la destruction, dudit tube qui est destiné à délivrer les gaz assurant la respiration du patient. Il peut donc en résulter des conséquences graves pour celui-ci, d'autant plus que les matières organiques utilisées pour la fabrication des tubes endo-trachéaux sont non seulement combustibles, mais peuvent également dégager des vapeurs caustiques ou toxiques.In fact, the material constituting such a known endotracheal tube generally absorbs infrared energy well, so that if anesthesia is delivered by this tube during an intervention by means of a laser, there is a risk of deterioration, and even the destruction of said tube which is intended to deliver the gases ensuring the breathing of the patient. It can therefore result in serious consequences for the latter, especially since the organic materials used for the manufacture of endo-tracheal tubes are not only combustible, but can also give off caustic or toxic vapors.
Il peut se faire que l'anesthésie ne puisse être pratiquée par les voies naturelles ou que, le patient étant déjà trachéotomisé, on n'utilise pas de tube endotrachéal,mais un tube de trachéotomie portant un ballon d'anesthésie,ou que l'on remplace, si le malade est déjà trachéotomisé, la canule dont il est appareillé par une canule souple munie d'un ballon permettant l'anesthésie.It may happen that anesthesia cannot be performed by natural means or that, the patient being already tracheotomized, one does not use an endotracheal tube, but a tracheostomy tube carrying an anesthesia balloon, or that the if the patient is already tracheotomized, the cannula with which he is fitted is replaced by a flexible cannula provided with a balloon allowing anesthesia.
Les inconvénients d'utilisation du faisceau laser lorsque l'anesthésie est délivrée par tube trachéotomique, et non par tube endo-trachéal, sont bien entendu les mêmes.The drawbacks of using the laser beam when anesthesia is delivered by tracheostomy tube, and not by endotracheal tube, are of course the same.
Pour tenter à remédier à ces inconvénients, on a déjà pensé à protéger le tube endo-tracheal ou le tube trachéotomique au moyen d'enroulements hélicoidaux d'une bande d'une matière réfléchissante de l'énergie infrarouge, telle que l'aluminium, ces enroulements étant par exemple fixés sur le tube au moyen d'un adhésif. Une telle solution peut être considérée comme acceptable pour la protection du tube lui-même, mais est sans effet pour protéger le ballon équipant le tube et qui a pour fonction d'assurer l'étanchéité et de permettre ainsi une ventilation efficace. Or, c'est justement le ballon qui est la partie dudit tube la plus vulnérable, car constitué d'une très faible épaisseur d'un élastomère sous tension
On a egalement pensé à realiser les tubes endo-tracheaux en une matière métallique.Mais alors, on obtient des tubes rigides dont l'introduction est traumatisante pour les voies respiratoires. -De plus, à cause du poli spéculaire d'un tel instrument, on risque des réflexions du faisceau laser sur des tissus sains ne devant pas être traités.In an attempt to remedy these drawbacks, it has already been thought of protecting the endotracheal tube or the tracheotomy tube by means of helical windings of a strip of a material reflecting infrared energy, such as aluminum, these windings being for example fixed on the tube by means of an adhesive. Such a solution can be considered acceptable for the protection of the tube itself, but has no effect on protecting the balloon equipping the tube and which has the function of ensuring sealing and thus allowing effective ventilation. However, it is precisely the ball which is the most vulnerable part of said tube, because it is made of a very thin thickness of a tensioned elastomer
We also thought of making the endo-tracheal tubes out of a metallic material. But then, we obtain rigid tubes whose introduction is traumatic for the respiratory tract. -Moreover, because of the specular polish of such an instrument, there is a risk of reflections of the laser beam on healthy tissue which should not be treated.
La présente invention a pour objet de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.
A cette fin, selon l'invention, le tube endo-trachéal ou trachéotomique pour anesthésie comportant un corps tubulaire servant à véhiculer les gaz de ventilation et ad'anesthésie et pourvu au voisinage de son extrémité distale d'un ballon d'étanchéité susceptible d'être gonflé, est remarquable en ce qu'il comporte entre ledit ballon et l'extrémité proximale du tube, à quelque distance dudit ballon, un bouclier thermique souple.To this end, according to the invention, the endo-tracheal or tracheotomic tube for anesthesia comprising a tubular body serving to convey ventilation and anesthesia gases and provided in the vicinity of its distal end with a sealing balloon capable of 'being inflated, is remarkable in that it comprises between said balloon and the proximal end of the tube, at some distance from said balloon, a flexible heat shield.
Ainsi, gracie à l'invention, il est possible d'obtenir un tube souple dans lequel le ballon, qui est la partie la plus fragile, est protégé par le bouclier thermique.Thus, thanks to the invention, it is possible to obtain a flexible tube in which the balloon, which is the most fragile part, is protected by the heat shield.
Un tel bouclier thermique peut se présenter sous la forme d'un disque coaxial au tube. Il peut être fixé sur celui-ci ou en être solidaire. Il peut être d'une seule pièce ou, au contraire, être constitué de plusieurs secteurs solidaires les uns des autres au voisinage de leur partie articulée et séparés les uns des autres par des fentes dont les bords se chevauchent.Such a heat shield can be in the form of a disc coaxial with the tube. It can be fixed on it or be integral with it. It may be in one piece or, on the contrary, consist of several sectors integral with each other in the vicinity of their articulated part and separated from each other by slots whose edges overlap.
De préférence, le bouclier thermique est constitué d'une matière souple semblable à celle du tube et contenant une dispersion d'une poudre métallique finement divisée comme une poudre d'aluminium, d'argent, d'or, etc... Ces particules métalliques absorbent et réfléchissent l'énergie reçue de l'impact du faisceau laser servant au traitement des tissus pathologiques.Preferably, the heat shield consists of a flexible material similar to that of the tube and containing a dispersion of a finely divided metallic powder such as a powder of aluminum, silver, gold, etc. These particles metals absorb and reflect the energy received from the impact of the laser beam used to treat pathological tissue.
Seul le bouclier thermique peut contenir la dispersion de poudre métallique finement divisée. Cepenciant, il est avantageux que la totalité du tube comporte une telle dispersion métallique, de sorte que sa résistance à l'énergie infrarouge est améliorée.Only the heat shield can contain the finely divided metal powder dispersion. However, it is advantageous for the entire tube to have such a metallic dispersion, so that its resistance to infrared energy is improved.
Dans le cas d'un tube endo-trachéal,la distance séparant le ballon du bouclier est choisie approximativement égale à 2 ou 3 cm de façon à permettre le franchissement en deux temps des cordes vocales.Dans le cas d'un tube trachéotomique, le problème du passage des cordes vocales ne se pose évidemment pas. Dans ces conditions, il est possible de placer le bouclier de protection thermique à quelques millimètres du ballon permettant l'étanchéité entre la trachée et le tube. Le diamètre du bouclier est choisi, dans les deux cas, légèrement inférieur au diamètre de la trachée à intuber.In the case of an endotracheal tube, the distance separating the balloon from the shield is chosen approximately equal to 2 or 3 cm so as to allow the vocal cords to be crossed in two stages. In the case of a tracheostomic tube, the the problem of the passage of the vocal cords obviously does not arise. Under these conditions, it is possible to place the thermal protection shield a few millimeters from the balloon allowing the seal between the trachea and the tube. The diameter of the shield is chosen, in both cases, slightly less than the diameter of the trachea to be intubated.
Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée.The figures of the appended drawing will make it clear how the invention can be implemented.
La figure 1 est une vue en perspective d'un tube endo-trachéal selon l'invention. Figure 1 is a perspective view of an endo-tracheal tube according to the invention.
la figure 2 est une vue de face agrandie d'une variante de réalisation du bouclier thermique.Figure 2 is an enlarged front view of an alternative embodiment of the heat shield.
La figure 3 est une coupe selon la ligne III-III de la figure 2.Figure 3 is a section along line III-III of Figure 2.
Le tube endo-trachéal ou trachéotomique selon l'invention, montré par la figure 1, comporte de façon connue un conduit principal 1 servant à véhiculer les gaz de ventilation et d'anesthésie et un canal auxiliaire 2, s'incorporant au conduit 1, et servant au gonflage d'un ballon 5, apte à assurer l'étanchéité avec les tissus de la trachée.The endotracheal or tracheotomy tube according to the invention, shown in FIG. 1, comprises in a known manner a main duct 1 used to convey the ventilation and anesthesia gases and an auxiliary channel 2, which is incorporated into the duct 1, and used for inflating a balloon 5, capable of ensuring sealing with the tissues of the trachea.
Conformément à l'invention, le tube comporte, en avant du ballon gonflable 5, un bouclier thermique souple 4.In accordance with the invention, the tube comprises, in front of the inflatable balloon 5, a flexible heat shield 4.
Sur la figure 1, ce bouclier thermique est formé par un disque solidaire dudit tube, orthogonalement à l'axe de celui-ci.In Figure 1, this heat shield is formed by a disc integral with said tube, orthogonally to the axis thereof.
En revanche, sur les figures 2 et 3, le mode de réalisation du bouclier thermique représenté est constitué de plusieurs secteurs 4 solidaires à leur base du conduit 1 et se recouvrant partiellement, à la manière de pétales. Les secteurs 4 se déforment facilement lors du franchissement de passages étroits, mais retrouvent élastiquement leur position naturelle lorsque le tube est en place dans la trachée.On the other hand, in Figures 2 and 3, the embodiment of the heat shield shown consists of several sectors 4 secured at their base to the duct 1 and partially overlapping, in the manner of petals. The sectors 4 are easily deformed when crossing narrow passages, but resiliently return to their natural position when the tube is in place in the trachea.
Le tube peut être fabriqué dans différentes matieres : les élastomères naturels ou artificiels , tels que le caoutchouc naturel, les polyisoprènes de synthèse,-les polychloroprènes, les polybutadiènes-styrènes ; les polybutadiènes, soit purs, soit en combinaison peuvent éventuellement convenir. Il en est de même des chlorures de polyvinyle plastifiés, des polyuréthanes. The tube can be manufactured in different materials: natural or artificial elastomers, such as natural rubber, synthetic polyisoprenes, polychloroprenes, polybutadienes-styrenes; polybutadienes, either pure or in combination, may possibly be suitable. It is the same for plasticized polyvinyl chlorides, polyurethanes.
mais il est préférable d'utiliser des polysiloxanes, tout particulièrement résistant à l'élévation de température et dont la dégradation thermique n'entraîne pas la formation de vapeurs caustiques ou toxiques. but it is preferable to use polysiloxanes, very particularly resistant to the rise in temperature and whose thermal degradation does not lead to the formation of caustic or toxic vapors.
En pratique, il suffit pour protéger le ballon 5 contre le laser, que le tube en silicone soit équipé au-dessus du ballon, d'un bouclier 4 de diamètre légèrement inférieur au diamètre de la trachée à intuber et d'une épaisseur d'environ 6 à 8/10 de mm, qui est par exemple fabriqué en silicone chargé en poudre d'aluminium.In practice, it is sufficient to protect the balloon 5 against the laser, that the silicone tube is fitted above the balloon, with a shield 4 of diameter slightly smaller than the diameter of the trachea to be intubated and of a thickness of about 6 to 8/10 mm, which is for example made of silicone loaded with aluminum powder.
Des essais expérimentaux ont montré qu'une proportion de 1 % d'aluminium en poids permet de garantir une résistance à 100 impulsions de 5/10 de seconde au rayon laser.Experimental tests have shown that a proportion of 1% of aluminum by weight makes it possible to guarantee resistance to 100 pulses of 5/10 of a second to the laser beam.
Toutefois, il est souvent avantageux de réaliser la totalité du tube en élastomère chargé de poudre métallique, utilisé pour la fabrication de bouclier 4. However, it is often advantageous to produce the entire elastomer tube loaded with metallic powder, used for the manufacture of shield 4.
