Description

  

  Canule pour pompe d'aspiration de salive.    L'invention a pour objet une canule pour  pompe d'aspiration de salive, utilisée par les  dentistes et chirurgiens.  



  Le dessin ci-joint montre, à titre d'exem  ple, une forme d'exécution en métal.  



  La     fig.        1.    est une coupe;  La     fig.    2 est une vue de face avec partie  en coupe.  



  La canule représentée possède un tube  coudé A à l'extrémité duquel vient se fixer  par une vis intérieure B, une calotte C, rivée  à la pièce B.  



  Le tube A présente deux fentes dépas  sant légèrement la longueur de la pièce B,  vissée dans cette forme d'exécution, et ter  minée par un cône.  



  La calotte C, rivée sur la vis B, est  percée de plusieurs trous D sur le pourtour.  La canule décrite permet à la salive qui  entre librement dans la calotte, d'être aspirée  dans le tube sans que les muqueuses soient  aspirées contre les parois de la calotte.  



  Le moyen de fixation de la calotte vissée  dans le tube et laissant passer la salive,  évite que     cette    calotte puisse se libérer du    tube et être avalée accidentellement par le  patient pendant une opération.  



  Les dimensions et les détails de construc  tion de la canule décrite pourraient varier,  mais il sera pratique d'employer comme  moyen de fixation de la calotte, une pièce  se vissant à l'intérieur du tube.



  Cannula for saliva suction pump. The object of the invention is a cannula for a saliva suction pump, used by dentists and surgeons.



  The accompanying drawing shows, by way of example, an embodiment in metal.



  Fig. 1. is a cut; Fig. 2 is a front view with part in section.



  The cannula shown has an elbow tube A at the end of which is fixed by an internal screw B, a cap C, riveted to part B.



  Tube A has two slots slightly exceeding the length of part B, screwed in this embodiment, and terminated by a cone.



  The cap C, riveted to the screw B, is drilled with several holes D around the periphery. The cannula described allows saliva which freely enters the cap to be sucked into the tube without the mucous membranes being sucked against the walls of the cap.



  The means for fixing the cap screwed into the tube and allowing saliva to pass through, prevents this cap from being able to free itself from the tube and be accidentally swallowed by the patient during an operation.



  The dimensions and construction details of the cannula described could vary, but it will be practical to employ as a means of securing the cap a part which screws into the interior of the tube.
