Definitions

  • the present invention relates to a connection for a tube to a mixer or mixer accessory.
  • a tube also called a capillary
  • a mixer For certain applications, especially in the dental or medical field, it is often necessary to connect a tube, also called a capillary, to a mixer in order to be able to apply the mixed material selectively, even in places that are difficult to access.
  • EP-A-0 091 773 discloses a connection of a pressure hose for compressed air controls, the hose being slotted and a clamp acting on it. Such an arrangement is not suitable for dental or medical technology.
  • EP-A-0 368 377 discloses an implantable injection chamber with a tube on the chamber into which a catheter is inserted, which is then fastened with a clamping ring.
  • US-A-4 013 310 relates to a connection for a tube to a connecting device, the tube being inserted into a flexible, slotted outlet of the device and a displaceable clamping ring securing the tube.
  • US-A-4 690 306 relates to a connection between an outlet piece and a mixer, but a screw ring is used for fastening.
  • US-A-4 771 919 discloses mounting a mixer on a cartridge by means of an adjustable screw ring.

  • Other snap-in elements such as noses and notches can also be used
  • the transition piece Before attaching a tube or capillary, the transition piece is pushed as far as it will go into the mixer outlet until the shoulder 9 comes behind the inner groove 6 on the mixer, snaps into place and holds the transition piece.
