    摘要: 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.

    摘要: Systems and methods handle air and rinsing fluid during fluid processing. The systems and methods eliminate air from a fluid processing system prior to, during, and after use. The systems and methods provide a connector assembly for establishing fluid flow from a fluid source. The connector assembly has discrete first and second passages that prevent communication between the fluid in first passage and the fluid in the second passage. Prior to system use, the connector assembly may be utilized in a priming function to remove residual air from a fluid circuit prior to use. The connector assembly may also be utilized after use to perform a rinse-back function.

    摘要: A pressure measurement device usable for monitoring pressure of fluids such as blood, waste, and replacement fluid in a blood treatment system provides a reliable signal and other benefits by virtue of a number of features of the various embodiments disclosed. The pressure of fluid carried by a vessel or tube is measured by measuring a change in shape of the vessel or tube via a sensor element contacting it. Materials, shape, and mechanical support cooperatively ensure that the little inelastic strain occurs and pressure measurements are repeatable. The embodiments are compatible with the use of disposable vessels and tubes.
