Definitions
- the present invention relates to a peristaltic pump device.
- Peristaltic pumps are notably, but not exclusively, used in the medical field to deliver drugs in liquid form, for example for infusions with a very regular flow rate.
- these pumps consist of a motor assembly and a cassette.
- the cassette essentially consists of a tube in which the liquid to be pumped circulates, this tube being deformable and pressed against a wall. Inside a loop formed by this tube, there is a plurality of rollers which are generally driven in rotation on themselves, these rollers punctually crushing the tube. The drive of the rollers is obtained by the rotation of the shaft of the motor assembly when the cassette is mounted on the latter. Between these crushing points, one defines in the tube of the chambers filled with liquid, the rotation of the rollers causing the displacement of these chambers from the entry of the tube until its exit.
- An object of the present invention is to provide a peristaltic pump device in which what has been called the cassette and which is to being discarded after each use has a simpler structure and therefore a lower cost.
- the peristaltic pump device is characterized in that it comprises: a first assembly comprising:
- each roller having a pivot axis and an active side face of revolution about said axis, and
- a plate mounted movable in said cavity along the axis of said shaft and having an orifice capable of allowing the free end of said shaft to pass
- a wall comprising at least one cylindrical portion
- the second set constitutes the equivalent of part of the cassette of the prior art and will be called the insert.
- This has a very simple structure since it is reduced to a portion of wall preferably provided with a cover and with the portion of deformable tubing which cooperates with the rollers. This structure is therefore very simple and inexpensive.
- the set of rollers is an integral part of the first set, that is to say of the motor device, the latter of course not being changed between two uses of the peristaltic pump.
- said cavity of the housing of the first set is substantially cylindrical of revolution around said shaft and has a bottom, and it is characterized in that said cavity further comprises guide means in translation of said plate in the direction of said shaft, and in that it is provided with elastic means interposed between said bottom and said plate tending to separate said plate from said bottom.
- said means for mounting the rollers comprise a plate mounted to rotate freely on said plate around the axis of the orifice of said plate and provided with a passage opposite said orifice capable of letting said shaft pass.
- FIG. 3 is a vertical sectional view of the pump device showing the insert and the separate motor device;
- Figure 4 is a view similar to Figure 3 but showing the insert engaged on the rollers of the motor device;
- FIG. 5 shows a part of the peristaltic pump device according to a first embodiment
- FIGS. 6a and 6b show a top view, respectively, of the engagement of the insert and of the insertion of the insert and of the rollers according to the first alternative embodiment
- FIG. 7 shows a partial view of the engine part of a second alternative embodiment.
- the peristaltic pump device consists on the one hand of a motor assembly and on the other hand of a second assembly constituting the insert.
- the insert 10 comprises a housing 12 which defines a cylindrical internal cavity 14.
- the cavity 14 is limited by a cylindrical side wall of the housing 16 corresponding to an angle at the center C greater than 180 * and which is for example of the order of 210 * , the wall of the cavity being completed by a massive portion 18.
- the upper edge of the wall 16 is preferably closed by a transparent cover or not 19.
- the lower end 20 of the wall 16 is open.
- the cavity 14 opens out at its lower end.
- a tubular conduit 22 made of a deformable material as will be explained later.
- this tubular pipe 22 has a cross section in the form of a substantially ellipse whose major axis is parallel to the direction of the height of the wall.
- the tubular conduit 22 is housed more precisely in a curved recess 24 on the internal face of the wall 16.
- the inlet end 22a and the outlet end 22b of the tube 22 are fixed in the solid part 18 of the housing of the insert 10.
- the tube 22 is thus completely immobilized inside the housing of the insert. As the shows Figure 1, the face of the tube 22 facing the interior of the cavity 14 is free.
- the engine part which bears the general reference 30 essentially comprises a housing 32 defining a cavity 34 capable of receiving the cassette 10 as will be explained later.
- the motor part 30 also comprises, mounted on the housing 32, a motor 36 of suitable type, the output shaft 38 of which protrudes inside the cavity 34 along the axis of revolution of the cavity XX '.
- the shaft 38 has, in this mode, a frustoconical free end 40.
- the shape of the internal cavity 34 of the housing 32 coincides with the external shape of the housing 12 of the cassette.
- the cavity 34 has a bottom 42 through which the shaft 38 passes through the opening 44.
- Inside the cavity 34 there is an assembly 46 for mounting rollers 48. In the particular embodiment described in connection with Figures 1 and 3, the number of rollers is equal to 3 and they are referenced 48a, 48b and 48c.
- the mounting assembly 46 essentially consists of a plate 50 whose external edge 50c coincides with the internal wall of the cavity 34.
- the plate 50 can move inside the cavity 34 while being guided in translation according to the XX 'direction.
- the plate 50 has an axial orifice 52.
- the plate 54 On the plate 50 is mounted a guide plate of the rollers 54.
- the plate 54 is rotatably mounted around the axis XX 'relative to the plate 50 but it is immobilized in translation relative to this same plate in direction XX '.
- This result is obtained by providing for example in the central part of the plate 54 a cylindrical sleeve 56 ending in a lip 58 which cooperates with a lower shoulder 59 of the center of the plate 50.
- the sleeve 56 of the plate 54 defines an axial orifice 60 of diameter d greater than the diameter of the shaft 38.
- the plate 54 has radial grooves 62a, 62b and 62c, the number of which is equal to the number of rollers 48.
- the plate 54 is completed by an upper plate 64 integral with the plate 54 and itself provided with radial slots 66a, 66b and 66c coinciding with the grooves 62a of the lower plate 54.
- Each roller 48a to 48c has a pivot axis xx 'materialized by a shaft 68, the ends 70 and 72 of which protrude from the end faces 74 and 76 of each roller.
- the ends 70 and 72 of the axis of each roller penetrate into the grooves 62 and 66 respectively of the lower plate 54 and the upper plate 64.
- the distance between these two plates is very slightly greater than the height h of the rollers of such so that they can pivot freely around their axis xx 'while being substantially immobilized in translation in the direction XX'.
- each roller comprises a side face, preferably curved, 80 which has around the axis xx 'a diameter D.
- a spring 78 or any other suitable elastic system is disposed in the cavity 34 of the motor device and is interposed between the bottom 42 of the cavity and the underside 50b of the plate 50. The spring therefore tends to maintain in the high position the plate 50 inside the cavity 54, the plate being retained by a shoulder 79 on the periphery of the cavity 34.
- the insert 10 is engaged around the rollers 48 of the motor device 30. This engagement is easily done since the rollers 48 can move freely towards the axis XX 'under the effect of contact between the part of the tube 22 which projects into the cavity of the insert and the lateral surface 80 of the rollers 48a to 48c. As shown in FIG. 4, at the end of this operation, a part of the lower end face 76 of the rollers 48 projects above the axial orifice 60 of the plate 54.
- FIG. 4 shows the insert engaged around the rollers 48.
- the rollers and the insert are held in the high position under the action of the spring 78 tending to push the plate 50 towards the upper end of the cavity 34 by means of the shoulder 79.
- the insert 10 and therefore the plate 50 are pressed in by compressing the spring 78.
- the frustoconical end 40 of T chandelier 38 progressively pushes the rollers 48a to 48c in. moving them away from the axis XX ', which of course tends to locally compress the tube 22 at the three contact zones.
- the rollers are guided by the radial slides 62 and 66.
- Figure 5 shows an alternative embodiment which facilitates the engagement of the insert 10 around the rollers 48 and the passage of the end of the shaft 38 between the rollers.
- FIG. 5 shows that the periphery of the lower face 76 of the rollers 48 is bevelled at 82.
- the free end of the shaft 38 which is then referenced 40 ′ has, in an axial plane, a curvature which goes in decreasing from the side wall 38a of the tree to its top 84.
- the return springs 86 or other elastic systems which tend to push the rollers towards the axis XX 'of the plate 50. These springs are interposed between the end 70 or 72 of the pivot axis of the rollers and the closed end 88 of the grooves 62 or 66.
- the insert 10 not being modified, we will only describe the modifications made to the motor means 30 '.
- the plate 50 ' is always provided with its axial orifice 52 and its shoulder 59.
- a sleeve 90 is mounted for free rotation in the orifice 52. It is immobilized in translation along the direction of the axis XX' and its chamfered end 92 protrudes above the upper face 50a of the plate.
- the plate 54 ' corresponding to the plate 54 of FIG. 3, has an axial bore 94 which is engaged around the sleeve 90, the latter being able to slide in the bore 94.
- the plate 54' has radial grooves 62 'in number equal to that of the rollers 48.
- Each groove 62 ' has one end which opens into the bore 94 and another closed end 96.
- a slide 98 In each groove 62' is mounted a slide 98.
- Each slide 98 is pierced with an orifice 100 intended to receive the lower end 72 of the pivot axis of a roller.
- the end 102 of the slide facing the bore 94 is rounded in a vertical section plane.
- a return spring 104 is mounted in each groove 62 'between the slider 98 and the closed end 96 of the groove. Under the effect of the spring 104, the end 102 of the slider 98 projects into the bore 94 while coming to bear on the bevelled part 92 of the sleeve 90.
- the upper plate 64 ' has the same structure as the lower plate 54' with its grooves 66 ', its slides 98' in which the upper ends 70 of the axes of the rollers 48 are engaged and its return springs 104 '.
- a pusher 106 In the axial bore 94 'is engaged a pusher 106 having a beveled end 108 on which the slides 98' are supported.
- the tray 50 and the insert are inserted into the cavity 34 of the housing. During this depression, the side wall of the shaft 38 completely pushes the rollers 48 so that they locally compress the pipe 22. The pump is then ready to be used.
- the roller 48a in Figure 6a has its pivot axis x, x 'which is arranged in the plane of symmetry AA of the motor device , the other two rollers 48b and 48c being arranged symmetrically with respect to the plane AA '.
- This particular positioning can be obtained by the combination of a position sensor mounted in the housing 32 detecting the effective position of the rollers, this sensor controlling a limited operation of the motor to bring the roller 48a to the desired position.
