Definitions

  • the present invention relates to a device for assembling a tubing on a peristaltic pump, comprising a support having a seat open laterally and whose shape is complementary to that of a portion of the tubing, the latter carrying an element of axial stop intended to be applied against a face of said support intersecting the axis of said seat, for retaining this tubing axially on this support against the tensile force exerted by the peristaltic pump on the tubing.
  • This assembly device generally comprises a support in which is formed a semi-cylindrical seat which can be accessed laterally by an opening parallel to the longitudinal axis of the seat, but whose width is less than the diameter of the section of this seat.
  • a semi-cylindrical seat which can be accessed laterally by an opening parallel to the longitudinal axis of the seat, but whose width is less than the diameter of the section of this seat.
  • the seat access opening has a width less than the diameter of this seat to prevent the accidental exit of this tube. Indeed, under the pinching and loosening action that the rollers of the peristaltic pump exert on a portion of the tubing, the latter could accidentally come out of its seat. Since, moreover, the rollers of the pump exert a tensile force on the tubing, the latter also comprises a collar which bears against a face of the support oriented transversely to the seat.
  • This assembly device has various drawbacks.
  • the installation of the tubing in the seat of its support requires, as has been said, a crushing of the tube.
  • This operation is not always easy to carry out, all the more so since the collar which cooperates with the support is generally molded, so that only a sufficiently flexible part of this tubing which is distant from this can be crushed. flange and then slide it into the seat to bring it into abutment against the transverse bearing face of the support.
  • Another drawback of this assembly device comes from the fact that nothing prevents the reversal of the tubing during assembly. It should indeed be known that such a tube is generally formed of various segments assembled to each other, each segment being made of a plastic material suitable for its function.
  • the object of the present invention is to remedy, at least in part, the above-mentioned drawbacks.
  • the subject of this invention is a device for assembling a tubing on a peristaltic pump according to claim 1, the preamble of which relates to document US-A-4 585 399.
  • Figure 1 is a front view of a peristaltic pump and the assembly device.
  • Figure 2 is a view along the line II-II of Figure 1.
  • Figure 3 is a perspective view showing the device in two separate parts.
  • FIG. 1 illustrates a tube 1 comprising two conduits 2 and 3 connected by a Y connection 4 to a common conduit 5 which is located upstream of a peristaltic pump of which only this part has been shown in this figure.
  • understanding of the invention namely a mobile 6 bearing rollers 7 distributed circularly around the axis of rotation 8 of the mobile 6 and a shoe 9 mounted pivoting about an axis 10, all integral with a frame B.
  • This shoe 9 has a semi-circular surface 11 concentric with the mobile 6.
  • a spring 1 (not shown) is used to elastically maintain this shoe 9 in a determined position relative to the mobile 6.
  • a segment 13 of the tubing 1 is placed between the semicircular surface 11 of the shoe 9 and the shoe 6.
  • the spacing between the mobile 6 and the shoe 9 is chosen so that each roller 7 compressively joins a portion of the wall of the segment 13 as the displacement of the roller 7 in the direction of the arrow F, opposite the semi-circular surface 11 of the shoe 9.
  • the length of this surface 11 being greater than the spacing between two rollers, it follows, according to the well known peristaltic drive mode, that a volume of liquid is thus advanced in the direction of arrow F by each roller 7 which moves along the semi-circular surface 11.
  • a support member 14 is fixed to the frame B on the upstream side of the peristaltic pump.
  • This support 14 is arranged to allow the assembly of the tubing 1 and comprises for this purpose a semi-cylindrical seat 15 whose diameter corresponds to that of the portion of tubing that this seat must receive.
  • This support 14 which is generally rectangular in shape is cut by an oblique face 14a which cuts the semi-cylindrical seat 15.
  • a groove 16 extends perpendicular to this oblique face 14a, passes through the semi-cylindrical seat 15 and enters the support 14, as illustrated by FIGS. 2 and 3.
  • the half-flange 17 engages in the groove 16 when the tubing part 5 is placed in the seat 15 of the support 14. Given their inclination, the groove 16 and the half-collar 17 maintain the part of tubing 5 in the semi-cylindrical seat 15. In fact, any traction exerted on this part of tubing 12 following the rotation of the mobile 6 in the direction of arrow F is reflected, by virtue of the inclination of the groove 16 and of the half-flange 17, by a force component acting on the tubing part 12, directed perpendicular to its longitudinal axis and towards the support 14 causing the self-locking of this tubing.
  • the tubing part 12 does not risk accidentally coming out of its seat 15, so that the lateral opening which gives access to this semi-cylindrical seat 15 can have a width equal to the diameter of the cylindrical section of the seat 15, the tubing being retained by the aforementioned force component.
