Definitions

  • the invention relates to a roller pump for peristaltic delivery of liquid and gaseous Media.
  • Roller pumps and pumps are used in many medical devices and devices in laboratory diagnostics Peristaltic pumps for various conveying tasks, mainly for the transport of liquids used because they have no direct contact with the pumped medium. Both types convey the pumped medium by means of a pump hose segment provided for this purpose is partially squeezed tightly from the outside and this crushing is then moved in the conveying direction is, so that the material to be conveyed in the hose must also continue to move. Before this Seals the hose at the end of the pump segment again, at the beginning of the Pump segment created the next sealing point, which then with the next delivery portion advanced.
  • the advantage of this method is that no part of the pump touches the material to be conveyed directly. This enables sterile and toxic substances to be conveyed.
  • the hose system with The pump segments are mostly disposable items and are disposed of after use.
  • a hose system often contains several pump segments for different pumping tasks. Confusion of one pump segment with another must be done when inserting the Hose system can be avoided safely, as well as a reversal of the insertion direction and thus the pumping direction. Especially in medical devices such as dialysis machines this requirement is often vital for the connected patient. That's why there are many Provide pump segments in this area with mechanical adapters and coding, that prevent incorrect insertion.
  • the number of existing in the hose system Pump segments are based on the task; in medical technology, they are devices with far more than ten pumps and hose clamp valves in use, in laboratory diagnostics up to 40 channels are required simultaneously (example laboratory cassette pump). The complexity of these hose systems often leads to a tangle that is difficult to see on hoses, pump segments and connecting elements. The correct insertion of all Pump segments are a particular problem here.
  • Another disadvantage is the costly production of such a hose system Tightness problems at the gluing points of the hose pieces and connecting elements and Dead spaces and dead ends in the hose system due to the spatially distant arrangement of Pump.
  • Another general problem with peristaltic pumps is the generally limited one Lifetime of the pump segment. Because the tube is actually round in cross section is cyclically flat rolled, there is a risk that it is particularly at its laterally extremely loaded Bends break prematurely and therefore leak.
  • the pump rollers have to To be able to build up pressure, press the pump hose so that the pressure point really is tightly closed, occlusion at zero distance. Through this tightness requirement in Pump segment, the bending radius at the pump segment cross section is very small when squeezing, a real kink. Therefore, there are generally only a few very flexible materials for these requirements suitable as a pump segment (e.g. silicone). The transition of these materials to that Other hose material (usually PVC) is often a further problem.
  • Roller pumps of various types are used for the hose systems mentioned.
  • One such is shown in US-A-3832 096.
  • This pump has several on a common Axis arranged rotating body, all rigidly connected to each other, by one and be driven by the same motor.
  • the flow is regulated by adjusting the individual adjustable counter bearing of each individual pump segment compared to the itself rotating roller of all rotating bodies. Examples with individual are also known Driving each rotating body, e.g. US 5443 451. It shows one out of four side by side arranged pumps existing four-pump block, in which each pump through from each other differently constructed gear shaft connections is driven. These drives sit to the right and left of the side of the pump block, so that no further baying a pump or a further four-pump block is possible.
  • a decisive step forward in solving the problems presented is the use of a flexible tube cassette made by thermoplastic molding with embossed Pumping segments.
  • the invention has for its object a roller pump for operation with such hose cassettes to sharpen that those shown in the prior art Overcomes disadvantages.
  • the narrow roller pump units are each separate Drives in any number according to the requirements of the flow of the Pump hose system embossed pump segments modularly arranged on one axis.
  • the structure of the roller pump is thus easy to service and clear.
  • a double security compared to conventional solenoid valves is realized by implementing a general Stop position of each roller pump unit in such a way that stationary roller pump units basically be brought into the state that two roles at the same time are engaged and double clamping takes place.
  • a roller pump 1 for operation with a hose cassette 2 is shown, wherein the individual roller pump units 4 sit on a common axis 6 and each have their own drive 14.
  • the sprung pressure rollers 7, 8 of the rotating body 5 of each roller pump unit act on a pump hose segment 3 Hose cassette 2.
  • the hose cassette 2 is on the roller pump units when the cover 9 of the roller pump 2 is open 4 placed. When the lid 9 is closed, the entire hose system is finished inserted.
  • All parts of a roller pump unit 4 are arranged on a mounting plate 15.
