Definitions
- the present invention is in the field of medical peristaltic systems.
- a peristaltic cassette system includes 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. By opting for such a resistance, it limits considerably the traction that could exert the tube on elements of the peristaltic cassette, p. ex. clips.
- 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).
- Figure 1 shows an open cassette case before gluing.
- Figure 2 illustrates the different bonding positions.
- Figure 3 shows a profiled tube.
- Figure 4 shows a graph for the operation of a conventional cassette with respect to flow accuracy.
- Fig. 5 shows a graph for the operation of a conventional cassette with regard to the pressure of the cassette.
- Figure 6 shows a graph for the operation of a glued tube cassette with respect to flow accuracy.
- Fig. 7 shows a graph for the operation of a cassette with a sticky tube as regards the pressure of the cassette.
- 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 two stages, closed box, 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 its attachment by clamping 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.
