摘要:
The invention relates to a device having a guide catheter for inserting a tracheal cannula into a tracheostoma. The invention proposes a device for inserting a tracheal cannula into a tracheostoma in such a way as to avoid an injury caused by the distal, frontal surface of the cannula. Such a device would be suitable for use with very flexible cannulas, cannulas with a small internal diameter, and/or cannulas with thick walls. The invention proposes that the guide catheter should have a shield that is made of a flexible material, that is fitted near the distal end of the guide catheter, and that has substantially the form of a distally oriented, conical tip. According to the invention, the tube of the guide catheter passes through the axis of this tip and has a basic outer diameter which, in its first state, is at least equal to the outer diameter of the tracheal cannula, and in its second state, as a result of deformation, is smaller than the internal diameter of the tracheal cannula, and can thus be withdrawn through the tracheal cannula.

摘要:
Elément d'étanchéité pour tubes endotrachéens, formant un joint étanche aux fluides entre la paroi externe du tube et l'ouverture dans laquelle le tube est introduit. L'un des désavantages que présente l'utilisation des éléments de joint classiques, à savoir de manchons gonflables, est représenté par les lésions qu'ils peuvent provoquer à la trachée. On évite ce désavantage en utilisant un élément d'étanchéité (50) comprenant une partie de collier (51) et un rebord pliable (53). Un ou plusieurs de ces éléments (50) sont positionnés sur le tube endotrachéen (55). Lorsque le tube (55) est introduit dans une ouverture, le rebord pliable (53) forme un joint entre la paroi externe du tube (55) et la paroi interne de l'ouverture.

Tube endo-trachéal ou trachéotomique pour anesthésie comportant un corps tubulaire (1) servant à véhiculer les gaz de ventilation et d'anesthésie et pourvu au voisinage de son extrémité distale (16) d'un ballon d'étanchéité (3) susceptible d'être gonflé un bouclier thermique souple (4) étant disposé entre ledit ballon (3) et l'extrémité proximale (1a) du tube, à quelque distance dudit ballon (3). Selon l'invention, ce tube est caractérisé en ce qu'il comporte un canal auxiliaire (6) débouchant (en 7) du côté dudit bouclier (4) opposé au ballon (3) et destiné à être parcouru par un gaz inerte. Traitement au laser des voies respiratoires hautes.
摘要:
A laryngeal mask that comprises a first element which is a rigid hollow tube essentially in the form of a "J", and which has a lengthwise opening along its entire length, and a second element that comprises a flexible tube, also essentially in the form of a "J", intended to be housed in the lengthwise opening of the first element, and which can be separated from it. This provides a configuration for a laryngeal mask that can change from having rigid properties to flexible ones at the doctor's will, without the need to interrupt the patient's supply of oxygen at any time.
摘要:
A device (1) for the tracheal intubation of and the administration of ventilation to a patient for rapid volume-compensating sealing of the trachea, wherein the sealing surfaces of a preferably fully and residually formed balloon-like film body (4) abut the wall of the trachea with a sealing pressure of the balloon (4) which is as constant as possible and follow the thoracic pressure acting on the balloon with the least possible time latency with regard to corresponding fluctuations of the balloon inflation pressure, and the trachea is kept sealed under such dynamic fluctuations or respiration synchronously alternating fluctuations of the balloon inflation pressure. This is enabled by a defined large lumen (7, 5) supply of the balloon inflation medium, the supplying lumen being measured in such a way that a sealing pressure-maintaining extracorporal volume compensation that works in a time synchronous manner can be achieved in the sealing balloon element.
摘要:
A laryngeal mask (1) comprising an air-way tube (2) and a mask portion (6) with an inflatable cuff (8) which is arranged around the airway tube (2) at the distal end thereof. A gastric tube (12) which extends at least partially along the outer surface of the airway tube (2), penetrates through the wall of said inflatable cuff (8) at a first location, extends through said inflatable cuff (8), and ends in a connection to an opening (12) in the wall of the cuff at a second location at the tip part of the laryngeal mask, so as to provide a passage through said circumferential cuff. With respect to a central mirror symmetry plane said gastric tube extends along the outer surface of the airway tube (2) in an asymmetrical manner, through said inflatable cuff (8) at the first location arranged asymmetrically with respect to said central plane, through said inflatable cuff (8), and ends in the connection to the wall of the cuff (8) at the second location at the tip part.
