Definitions
- the present invention relates to improvements made to peristaltic pumps, especially those involved in irrigation devices and suction of physiological fluids, with regulation automatic flow and pressure.
- Peristaltic pumps including a tube flexible transfer pinched successively by rollers describing one behind the other a closed circuit, in particular rollers carried by a rotor, are of use frequent for the transfer and pressurization of aggressive or sterile liquids (see for example document CH-A-433 992.) Whatever their shape and number of their rollers, pumps current peristaltics do not require, at a time whatever their functioning, that two rollers simultaneously active. The enclosed space inside of the pump tube and delimited by these two rollers constitutes the liquid transfer chamber.
- Peristaltic pumps are the type of pump preferred in medical applications, in particular in extracorporeal circulation devices or in the irrigation systems of the cavities seat of a surgical intervention, such as urology or arthroscopy, where these pumps are already in use currently.
- a medical device known using a peristaltic pump we can here cite the surgical irrigation and suction apparatus described in documents FR-A-2642297 and WO-A-9008562.
- the peristaltic pumps available on the market generally deliver a cyclical flow, presenting instantaneous variations in flow that can exceed 20 to 30% of the average flow of these pumps. This is illustrated schematically by the diagram in Figure 1, where the time t is plotted on the abscissa, and the flow D in ordered.
- the present invention aims to eliminate these disadvantages, providing a peristaltic pump improved, as described in claim 1, provided with an integrated device for flow regulation, automatically compensating for variations this in a simple, economical way by manufacturing and efficient, according to a principle of reliable and precise operation, and with a configuration allowing easy separation and speed of the rotor relative to the stator, for the purpose of security and interchangeability.
- the profile to give to the stator, in the area particular considered, must therefore be a function of rotor rollers diameter, tube characteristics transfer used (inside and outside diameters, hardness), and the pressure exerted by the rollers on the transfer tube, that is to say the crushing of this tube.
- the diagram of the figure 2 represents the variation of the volume V of a room transfer according to the pinch P of the tube.
- the axis ordinates represents, in percentage, the variation of volume of a transfer chamber under the effect of pinching exerted by a roller, in other words, the volume occupied by this roller inside the transfer tube.
- the roller realizing during the complete action compression of the tube walls 0.5 mm.
- the curve C of variation of the volume V relative to the height of the roller takes a form approximately parabolic.
- the shape given to the stator in the area of gradually increasing radius takes into account counts the intrinsic characteristics of the tube system transfer / roller, shown in Figure 2, to make the volume change proportional to the angular variation.
- the variation to be spread over 30 °, pinches are determined from the diagram of figure 2 so that 1 ° of angular variation corresponds to 3.33% change in volume.
- the variation of the radius is a function, determined experimentally, in which the angle intervenes, the diameter of the transfer tube, the diameter of the rollers and the prestress applied to the tube in the area of constant radius.
- the previous example is repeated below, with numerical data concerning the values of rays.
- the pump rotor can be mounted on a carriage driven by a jack, allowing quick release in the radial direction, in particular in the event of overpressure not under control.
- the "tangential" arrangement also allows design the stator as a removable and easily interchangeable, in particular a part forming part part of a single-use tubing, and the characteristics are related to this tubing, which has its importance in medical applications and surgical.
- the device that is the subject of the invention provides particularly simple and economical, at the outlet of the pump, flow and pressure variations which can be ⁇ 2% compared to the nominal values.
- FIG. 4 very schematically shows a pump peristaltic, which includes a flexible transfer tube 1, a fixed body or stator 2 and a rotor 3 of general shape cylindrical, mounted rotating around an axis 4 orthogonal to the direction of the tube 1.
- the stator 2 here has a recess 5 of particular profile, specified below.
- the rotor 3 carries, at its periphery, a plurality rollers 6 distributed at regular angular intervals, for example twelve rollers 6 separated from each other by angular intervals of 30 °. In a certain area from their circular trajectory, the rollers 6 come pinch the transfer tube 1, pressing it against the bottom of recess 5 of stator 2. Between two rollers 6 pinching the tube 1 has a zone convex 7 forming liquid transfer chamber, at least two rollers 6 being simultaneously active at an instant any in the area of constant radius and delimiting thus a transfer chamber closed to its two extremities.
- the recess 5 of the stator 2 mainly extends along an arc, so with a constant radius, in being centered on the axis 4 of the rotor 3.
- this recess 5 has a particular profile in an area 5a located on the side of the liquid outlet, area which extends over an angle at least equal to the angle separating the rollers 6 (30 ° in the example given).
- the bottom of the recess 5 comprises, in the area considered, radii R1, R2, R3, .. Rn progressively increasing.
- the useful cross-section of the liquid is therefore increasing downstream, which compensates for the variation in volume observed during the escape of a roller 6, so as to obtain a flow of liquid D practically constant at the pump outlet.
- the rotor 3 of the peristaltic pump can be quickly removed from the stator 2, in the radial direction as indicated by an arrow F, thus releasing the transfer tube 1, in particular in the event of uncontrolled overpressure.
- the rotor 3 is mounted on a carriage driven by a jack, not shown.
- FIG 5 a unit of fluid management for endoscopic surgery, involving the application of a peristaltic pump such as previously described, designated as a whole by the item 8, whose stator 2 and rotor 3 appear partially.
- the stator 2 is here designed as a part molded removable, shown alone in Figure 6, which is an integral part of sterile tubing 1 for use unique.
- This stator 2, removable and interchangeable, is mounted on a support 9, itself fixed on the front of the device.
- stator 2 has in particular a profiled groove 5.5a receiving the zone of the tubing 1 called to cooperate with the rollers carried by the rotor 3, the longitudinal profile of the groove 5, 5a corresponding to the definition given previously. At both ends of this groove are formed of eyelets, respectively of inlet 10 and outlet 11, crossed by the pipe 1 and ensuring the maintaining this on the stator 2.
- the stator 2 presents here again another groove or surface 12, straight receiving a part of tubing which does not cooperate with the rotor 3.
- the stator 2 has, on its face opposite to grooves 5,5a and 12, a dovetail conformation 13, which cooperates with a complementary conformation provided on the fixed support 9.
- the removable mounting of the stator 2 is performed by cooperation of these conformations in dovetail, the extraction of stator 2 being done in the direction indicated by the arrow G in the figure 5.
