Definitions

  • Peristaltic pumps are e.g. used in dialysis for blood transport.
  • Usual are roller pumps, in which a rotating roller carrier is provided, wherein the rollers gradually compress a piece of the tube over its length, thus conveying the liquid forward.
  • rolling the rollers on the hose creates friction (rolling resistance) and wear. The speed can therefore be relatively low.
  • a peristaltic pump in which the hose is pressed by the side of a pivotable, successively operated pressure fingers against a support surface for the hose.
  • a rotating eccentric is provided, which acts on the other side of the pressure fingers.
  • the peristaltic pump consists of many parts, has a large volume and is prone to failure and expensive.
  • Out FR 1 430 288 is a hose pump with a receiving part for a flexible hose in a recess and a ring with a plurality of radially extending punches which are pressed with their outer ends against the tube lying in the recess known. Furthermore, acts on the inner end of the punch, a motor-driven, non-circular rotor such that the punch is pressed during the rotation of the rotor progressively against the hose and then moved back in the opposite direction to release the hose one after the other.
  • the stamps are wrapped at their outer ends by an elastic band, which presses the punch with their inner ends against the rotor.
  • the stamps are in holes a ring guided longitudinally displaceable.
  • the peristaltic pump is made up of relatively many individual parts consuming.
  • the invention has for its object to build a peristaltic pump of a few items and to prevent rolling resistance, so that higher speeds are possible and the wear of the hose is low.
  • 1 is a pump body and 1a a receiving part, for. B. plastic, designated for a hose 2.
  • the hose 2 is made of flexible material and is located in a recess 3, which results from pump body 1 and receiving part 1a.
  • the recess 3 is closed by a plastic cover 4, which is omitted in Fig. 1.
  • a wheel 5 is arranged with a plurality of approximately radially located punches 6, which are interconnected by resilient webs 7.
  • the stamp 6 are with their outer ends by a non-circular, z. B. elliptical rotor 8 progressively pressed against the tube 2 and lie with their inner ends on the rotor 8 at.
  • z. B. in the direction of arrow 9
  • the tube 2 is compressed by the plunger 6 progressively peristaltic and the punch 6 are then moved back to release the tube 2 in succession. This will be liquid from the entrance 10 to the exit 11.
  • An electric motor 12 drives the rotor 8.
  • FIG. 3 shows a variant in region III of FIG. 2.
  • a yielding material 14 is applied to the punches 6 opposite the tube bed 13 of the recess 3, which prevents excessive squeezing of the tube 2.
  • the punch 6 may be formed resiliently in its longitudinal direction.
  • Fig. 4 is a U-shaped receiving part 15 in which the tube 2 is located between serving as stops 16 sides, which rests on the elastic material 14 and is movable in the direction of the tube bed 13 of the recess 3.
  • the pressing path of the hose 2 is limited. The latter is not completely compressed and thus z. B. lowered the hemolysis rate of blood pumps.
  • Fig. 5 shows that the hose 2 between the wheel 5 (punch 6) and the hose bed 13 can be biased so that the flexing is reduced.
  • a further, unbiased hose 2a is arranged.
  • the hose pump can therefore work simultaneously with several hoses.
  • FIG. 6 In the variant of FIG. 6 is located at the inner ends of the punch 6, a flexible ring 17 and between this ring 17 and the rotor 8 are rolling elements 18, which are guided by a flexible cage 19. Sliding friction between the punches 6 and the rotor 8 is thereby prevented.
