  • Medical flushing pump comprising two suction lines
    Patent number: 11925744
    Abstract: The present invention relates to a device for flushing a body cavity with a fluid, the fluid being pumped by means of two lines from the body cavity. The respective pumping capacity is regulated via controllable pinch valves, the two pinch valves being coupled in an antiparallel manner.
    Type: Grant
    Filed: December 4, 2019
    Date of Patent: March 12, 2024
    Assignee: W.O.M. WORLD OF MEDICINE GMBH

  • Method for the open-loop control of an electrically controllable valve in a vehicle transmission
    Patent number: 11913506
    Abstract: A vehicle transmission includes a hydraulic circuit and a control unit. The control unit is configured to: obtain (20) a target pressure specification; convert (26) the target pressure specification into a target volume flow rate; determine (42) a valve volume flow rate as a function of the target volume flow rate and as a function of parameters that represent system properties of the hydraulic circuit; determine (46) a pressure drop at a valve due to flow forces as a function of the valve volume flow rate; determine (48) a compensated valve output pressure as a function of the valve volume flow rate and the pressure drop; determine (58) the electric control current as a function of the compensated valve output pressure; and activate a valve with the electric control current.

  • Medical Fluid Pump with Possibility of Remote Assistance
    Publication number: 20230364359
    Abstract: The present invention relates to operating modes of a medical device for support and device training by a service person connected via data line. In particular, the invention relates to the simulation of operating modes of an insufflator by means of a computer located elsewhere, for example, in a training center. The invention further relates to the simulation of operating conditions of a medical fluid pump by means of a computer located at another location, e.g., in a training center.
