Definitions

  • This invention relates to gas-treatment devices of the kind for a tracheal tube including a housing containing one or more gas-treatment elements through which gas passes to a tracheal tube, the device including a tracheal coupling adapted for connection with the tracheal tube and a suction port substantially aligned with the tracheal coupling.
  • the invention is more particularly concerned with devices such as HMEs and filters adapted for attaching to the machine end of a tracheal tube.

  • HME heat and moisture exchange device
  • HMEs When the patient inhales, gas passes through the exchange element in the opposite direction and takes up a major part of the heat and moisture in the exchange element so that the gas inhaled by the patient is warmed and moistened.
  • HMEs are low cost and disposable after a single use. They can be connected in a breathing circuit or simply connected to the machine end of a tracheal tube and left open to atmosphere where the patient is breathing spontaneously.
  • HMEs are sold by Smiths Medical International Limited of Hythe, Kent, England under the Thermovent name (Thermovent is a registered trade mark of Smiths Medical International Limited), by Hudson RCI AB under the TrachVent name (TrachVent is a registered trade mark of Hudson RCI AB), by DAR, Medisize, Intersurgical and other manufacturers.

  • the suction port is usually closable by a tethered cap. The problem with suctioning in this way is that the user is exposed to contamination on the outside surface of the suction catheter when this is withdrawn from the tube. The suction catheter has to be handled carefully to avoid cross contamination and must be disposed of after a single use.

Abstract

L'invention concerne un dispositif HME (10), pour un tube trachéal (1), qui possède un boîtier (11) ayant un élément HME (15) et (16) à chaque extrémité et un couplage trachéal central (17) qui s'adapte sur le raccord d'extrémité de machine (5) du tube trachéal. Un orifice d'aspiration (20) est directement opposé au couplage trachéal (17) et présente un filetage externe (21) et une soupape à clapet interne (22). Un agencement de cathéter d'aspiration de système fermé (30) possède un raccord d'extrémité de patient (31), fileté à l'intérieur, qui se couple de façon étanche à l'orifice d'aspiration (20). Un cathéter d'aspiration (35) s'étend du raccord d'extrémité de patient (31) à un raccord d'extrémité de machine (40) conçu pour être relié à une source d'aspiration (41), (42), (43). Une enveloppe de protection souple (46) s'étend autour du cathéter (35) et le long de celui-ci, du raccord d'extrémité de patient (31) au raccord d'extrémité de machine (40). Le cathéter d'aspiration (35) peut être avancé dans le tube trachéal (1), à travers le dispositif HME (10) par manipulation à travers l'enveloppe (46) sans besoin d'un contact direct avec le cathéter.
