  • Patent number: 8042838
    Abstract: Devices can use various features to prevent the disconnection of connectors used in medical treatments. For example, a disconnection prevention member can have ends which hold luer connectors such that a male luer connector is prevented from separating from a female luer connector. The member can thus prevent disconnection of luer connectors that are incompletely mated.

  • Patent number: 7112273
    Abstract: A method and device for adjusting a volumetric flow balancing system for an extracorporeal blood treatment system receives a pressure signal and calculates a compensation factor that is used to adjust the relative flow rates of the volumetrically balanced fluids. For example, in a hemofiltration system, the flow of waste and and replacement fluid may be balanced volumetrically. Ultrafiltrate may be pumped in a bypass circuit in such a system. The rate of ultrafiltrate flow may be adjusted by the compensation signal. The compensation signal may be empirically derived.
