Definitions

  • the present invention relates to a peristaltic pump which may be used in the medical field, e.g. administration of drugs or of contrast media, peritoneal dialysis, etc... More precisely, the invention relates to a peristaltic pump of the "membrane" type.
  • Peristaltic pumps of the "membrane" type comprise a pumping cavity covered by a flexible membrane. Fluid is moved in the cavity by a moving pressure wave applied to the membrane.
  • the pressure wave can be obtained by a plurality of pressure elements situated along the cavity or by one or some moving pressure elements. Examples of such peristaltic pumps can be found in patent documents US 5 044 902, DE 197 17 452, DE 199 226 12 or DE 1 528 971.
  • the cavity contains an inlet and an outlet, the fluid has to be directed along a specific path (the pumping path).
  • a sealing element has to be placed between the inlet and the outlet.
  • the sealing element is made of a ridge forming part of the membrane.
  • the driving shaft is mounted in an axial bearing which permits the drive shaft to move axially, i.e. against the action of a spring.
  • the present invention provides a solution to the above cited problems. It concerns a peristaltic pump which comprises :
  • the sealing ridge is made of an elastomeric material which allows the sealing ridge to collapse.
  • the sealing ridge is designed to reach a position which places the complete membrane external face which is pressed in the same plane.
  • the groove contains a zone of greater depth. This deeper forms a part of the permanent fluid tight sealing segment.
  • the sealing ridge being designed to tightly fill the deeper zone.
  • One preferred embodiment for fixing the membrane to the pump body consists in providing the pump body with a second groove and in providing the membrane with a second ridge.
  • the second ridge is designed to be located in the second groove and to therefore tightly fix the membrane to the pump body.
  • the movable pressure element is a ball which, preferably, is rotatably fixed to an axis forming part of the driving means.
  • the axis is parallel to the membrane.
  • the groove forms a portion of a circle.
  • the groove forms at least a complete circle.
  • the groove may contain a fluid inlet and a fluid outlet. The permanent fluid tight sealing segment being then located on the shortest distance separating said inlet from said outlet. This forces the fluid to move on the greatest distance.
  • the groove may consist of a complete circle and two connected branches, one branch containing the inlet and the other branch containing the outlet.
  • the driving means may comprise a crown with a diameter at least identical to the first groove diameter.
  • the crown is adapted to be in close contact with the membrane when the membrane is not pressed by said movable pressure element. Such a configuration ensures a more regular flow in the channel.
  • the peristaltic pump may also contain several balls which, preferably, are separated by a rigid element being in close contact with the membrane.
  • the rigid element may contain several balls of relatively small diameter which are adapted to freely rotate on the membrane when the driving means are activated.
  • the pump body face contains at least another cavity forming part of an element such as a valve, a pressure sensor or a hub chamber.
  • the other cavity is also covered by the membrane.
  • the peristaltic pump according to the invention may be incorporated in a liquid distribution system similar to the one disclosed in international patent application PCT/CH2004/000480 filed by the applicant of the present invention.
  • the membrane is tightly fixed to the pump body.
  • the peristaltic pump comprises a pressure sensor located within the channel entry, the pressure sensor being connected to a flow compensating means, including e.g. a microprocessor, in such a way that any pressure difference recorded by said pressure sensor would adapt the fluid flow accordingly.
  • a flow compensating means including e.g. a microprocessor
  • the pressure sensor may be located within the channel exit.
  • the peristaltic pump comprises flow compensating means, based on membrane wear, which is adapted to automatically correct the fluid flow after a certain time and/or a certain number of pumping cycles.
  • Figure 1 shows a pump according to the invention including all essential elements.
  • Figures 2 to 9 show some of the elements of figure 1 which are taken separately.
  • the pump body 3 contains a circular groove 4 which extends in two parallel branches 6.
  • Each branch 6 contains an inlet or an outlet 10 through which liquid can enter or exit the circular groove 4.
  • the groove 4 and the branches 6 are covered by a membrane 2 made of flexible material.
  • the membrane 2 is covered by a membrane plate 1 which is fixed to the pump body 3.
  • the membrane is provided with an external ridge 11 and an internal ridge 12 which are located in a corresponding external groove 13 and an internal groove 14 contained in the pump body 3.
  • the membrane 2 is not covered by the membrane plate 1 in the central part and above the groove.
  • the groove 4 contains a zone of greater depth 17 having a transversal groove 5.
  • the membrane 2 On its internal face, the membrane 2 contains a protruding part 19 with a transversal ridge 20 which represents a negative reproduction of the groove deeper zone 17 and transversal groove 5.
  • This configuration forms a resting fluid sealing segment in the groove 4, i.e. in order to go from the inlet to the outlet, liquid is forced to use the groove longest path.
  • the membrane 2 On its external face, contains a cavity 18 which is approximately identical in shape to the zone of greater depth 17 and the transversal groove 5.
  • a ball bearing unit 8 is rotatably positioned above the membrane central part.
  • the ball bearing unit 8 contains several freely rotating balls 7 which can freely rotate around axis 9 which are parallel to the membrane 2.
  • the ball bearing unit 8 is mounted rotatable around a vertical axis so that the balls 7 can move along the groove 4.
  • the bottom part of the ball bearing unit 8 forms a crown 15.
  • the crown segments 16 which are situated between the balls 7 are in close contact with the membrane upper face.
  • FIG. 10 shows a possibility to include a pump according to the invention in a liquid distribution system, e.g. as defined in international patent application PCT/CH2004/000480.
  • the liquid distribution system may contain several cavities 21 forming part of a valve, pressure sensor, hub chamber or any similar object.
