Definitions

  • the present invention is in the field of medical peristaltic systems.
  • a peristaltic cassette system known for example from the document WO 03 / 097156A1 comprises a housing having a housing for receiving a tube portion and rollers.
  • a peristaltic cassette requires a compressive force of the tube by the rollers sufficient to ensure the tightness of the volume of liquid between two rollers. This force, associated with the rotation of the rollers driven by the motor shaft, can cause longitudinal sliding of the tube in the housing housing.
  • the housing comprises tube attachment means arranged along the tube housing so as to prevent the longitudinal displacement of a tube which would be disposed in said housing.
  • the invention is also characterized in that the tube attachment means are adapted to withstand a pressure greater than 2 bar.
  • peristaltic tube Various means for fixing the peristaltic tube can be envisaged.
  • bonding the use of an injected profiled tube, welding, vulcanization or melting of material (for example by ultrasound).
  • the casing of the cassette has 5 cavities along the raceway defining 5 bonding areas of the tube on the housing. 5 corresponding openings allow the introduction of the glue.
  • Bonding is carried out in 2 stages, closed housing, with the rollers and the motor shaft guaranteeing the position of the tube and its adhesion to the raceway (see figure 2 ). This bonding also ensures the closure of the two half-casings of the cassette.
  • Fixing the tube on the casing of the cassette can also be achieved by providing the tube with a profile having a longitudinal section, cut or not; allowing it to be clamped between the two half-casings of the cassette (see figure 3 ).
  • the invention was tested on a cassette by gluing the tube. A first series of preliminary tests showed a noticeable improvement in performance as shown by the flow and output pressure curves shown on graphs 1 to 4.

Claims (3)

  1. Gehäuse für eine peristaltische Kassette mit einer Schlauchaufnahme, die einen Kreisbogen bildet, und Schlauchbefestigungsmitteln, die so entlang der Aufnahme angeordnet sind, dass die Längsverschiebung eines in der Aufnahme angeordneten Schlauchs verhindert wird, wobei die Schlauchbefestigungsmittel geeignet sind, einem Druck von mehr als 2 bar zu widerstehen, wobei jedes der Schlauchbefestigungsmittel einen Hohlraum aufweist, der geeignet ist, eine Klebstoffmenge aufzunehmen, dadurch gekennzeichnet, dass der Hohlraum einen Durchgang bildet, der das Innere mit dem Äußeren des Gehäuses verbindet.
  2. Gehäuse nach Anspruch 1, das aus zwei Halbschalen besteht, dadurch gekennzeichnet, dass sich mindestens ein Teil der Kontaktzone der beiden Halbschalen auf der Höhe der Aufnahme befindet, wobei die Befestigungsmittel angeordnet sind, auch die Schließung der beiden Halbschalen zu gewährleisten.
  3. Gehäuse nach Anspruch 2, mit einem Schlauch, der mit einem Profil mit einem gegebenenfalls abgeschnittenen Längsabschnitt versehen ist, wodurch er durch Festziehen zwischen den beiden Halbschalen der Kassette befestigt werden kann.
