  • Patent number: 11395876
    Abstract: A pump module for an infusion pump includes a plunger-cylinder unit that can be coupled to the infusion pump in order to deliver fluid from a fluid feed line into a fluid drain line to a patient. The plunger-cylinder unit has a delivery chamber that is fluidically connected to the fluid feed line and the fluid drain line. The delivery chamber is delimited by the cylinder (14). The plunger can be moved linearly/back and forth in the axial direction. A plunger seal seals the plunger in relation to the cylinder. The section of the wall of the cylinder, over which the plunger seal passes during the back-and-forth motion of the plunger, is sealed in a sterile manner in relation to the surroundings.

  • Patent number: 11116894
    Abstract: A medical pump device for delivering a medical fluid includes a base body and elastomeric hollow membrane secured to the base body and arranged in such a way that a pump volume for filling with medical fluid is formed between the base body and hollow membrane. The hollow membrane, in an at least partially filled state of the pump volume, is elastically extended and exerts a delivery pressure on the pump volume. The medical pump device has a sensor system set up to determine the extension of the hollow membrane such that, by using the extension that is thus determined, filling level information concerning the filling state of the pump volume is determined. The medical pump device can be used in infusion or transfusion arrangements.
