A differential pressure based flow sensor assembly and method of using the same to determine the rate of fluid flow in a fluid system. The sensor assembly comprises a disposable portion and a reusable portion. A flow restricting element is positioned along a fluid flow passage between an inlet and an outlet. The disposable portion further has an upstream fluid pressure membrane and a downstream fluid pressure membrane. The reusable portion has an upstream fluid pressure sensor and a downstream fluid pressure sensor. The upstream fluid pressure sensor senses the upstream fluid pressure at a location within the fluid flow passage between the inlet and the flow restricting element. The downstream fluid pressure sensor senses the downstream fluid pressure at a location within the fluid flow passage between the flow restricting element and the outlet. The process utilizes output of the sensors to calculate the flow rate of the fluid.

A medical fluid machine includes (i) a pump that pumps a medical fluid and (ii) a heater that heats the medical fluid, the heater including an electrically insulative housing, at least one flat sheet of electrically conductive material suitable for contacting the medical fluid, the sheet disposed within the insulative housing, the sheet defining a flow path for the medical fluid in which the medical fluid changes direction at least one time, a primary coil of a transformer located outside the insulative housing, the primary coil configured to induce a current into the at least one conductive sheet, creating heat that may be transferred to the medical fluid.

Dialysis system having inductive heating

Apparatuses and methods for providing sterile connection during, for example, dialysis therapy. The present invention provides a connector and a cap therefore that easily and readily attaches to a dialysate container and a catheter inserted into a patient's peritoneal cavity. The connector and the cap enable the dialysate to readily transport between the container and the peritoneal cavity while minimizing the potential of contamination therein due to, for example, handling during use. The connector includes a shell that encloses a cap. The cap houses a slit septum and also includes a sealed disinfectant within an interior receptacle. When the catheter or catheter set attaches to the cap, the seal breaks and the disinfectant spreads over the threads between the catheter set and the cap.
