Patent number: 11701465Abstract: A sensor system for a volumetric pump operating according to the linear peristalsis principle includes at least one sensor unit; at least one sensor transmitter unit; and a sensor output signal processing unit. The sensor transmitter unit is arranged to apply a detection variable varying as a function of a travel position to the sensor unit along a predetermined travel along which a fixedly arranged sensor unit and a movably arranged sensor transmitter unit or a movably arranged sensor unit and a fixedly arranged sensor transmitter unit are moving relative to each other. The sensor unit is configured to output a detection signal corresponding to a travel position on the basis of the varying detection variable. The sensor output signal processing unit is arranged to receive the detection signal output by the sensor unit and discriminate at least three travel positions on the basis of the received detection signal.Type: GrantFiled: May 22, 2018Date of Patent: July 18, 2023Assignee: B.

Patent number: 11497861Abstract: An injection device includes a cylinder having a cavity for receiving a liquid. A passage is connected to the cavity for inflow and/or outflow of the liquid. The passage can be connected to an injection component. A shut-off valve has a valve body and a flexible sealing ring with an opening. The valve body, proceeding from a release position in which the passage is freed, is at least partially movable through the opening of the sealing ring to a blocking position in which the valve body engages behind the opening so that movement of the valve body to the release position is blocked and the passage is sealed off against proximally directed flow. An adapter body is connected to the cylinder. The shut-off valve is arranged at a proximal end of the adapter body and at a distal end of the cylinder. The device can be used in a syringe.Type: GrantFiled: September 20, 2018Date of Patent: November 15, 2022Assignee: B.
