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.

Apparatuses, devices, systems and methods for detecting access disconnection are provided. In one embodiment, a medical fluid system includes (i) a medical fluid machine and (ii) a device operable with the medical fluid machine, the device configured to provide electrical contact with a medical fluid, the device including (a) a tube used during dialysis therapy through which the medical fluid can flow, and (b) a conductive element configured to self-sealingly pierce the tube, the conductive element having a first portion exposed to the medical fluid and a second portion external to the tube.

Systems and methods relating to dialysis therapy, particularly continuous flow dialysis therapy, are provided. The present invention includes a single closed fluid path along which a minimal amount of therapy fluid including dialysate is fed into, continuously circulated and cleaned such that a therapeutic effective amount of solutes, excess water and the like can be removed from the patient connected to the closed fluid loop during treatment.

The present invention relates to a blood dialysis apparatus, in which a plural number of adequate dialysis therapy data (time-series data), wherein an estimated dry weight is closely similar to the dry weight, are memorized and thus it can be easily determined whether or not the subsequent dialysis therapy process achieves adequate therapeutic effects closely similar to the dry weight, and a blood dialysis method. A blood dialysis apparatus comprising: a dialytic treatment unit by which water is removed in accordance with the water removal amount determined based on an estimated dry weight and dialysis therapy is conducted; a BV detection unit (9) by which BV of the blood under extracorporeal circulation is measured at multiple points through time in the course of the dialysis therapy by using the dialytic treatment unit to thereby give time-series data; a determination unit (10) by which it is determined whether or not the estimated dry weight is closely similar to the dry weight after the completion of the dialytic therapy by using the dialytic treatment unit to thereby determine the adequacy of the dialysis therapy; and a memory unit (11) by which a plural number of the time-series data of the dialysis therapy having been judged as adequate by the determination unit (10) can be memorized.

Methods of producing macromolecular compositions and using same are provided. The method includes preparing a resin material; forming an acetyl group on the resin material; and oxidizing the acetyl group via a one-step reaction including reacting a sulfoxide and an acid with the acetyl group to form a ketoaldehyde group. The macromolecular compositions are capable of removing an effective amount of one or more constituents from a physiological solution, such as urea during dialysis therapy.

Dialysis systems and methods are described which can include a number of features. The dialysis systems described can be to provide dialysis therapy to a patient in the comfort of their own home. The dialysis system can be configured to prepare purified water from a tap water source in real-time that is used for creating a dialysate solution. The dialysis systems described also include features that make it easy for a patient to self-administer therapy. For example, the dialysis systems include disposable cartridge and patient tubing sets that are easily installed on the dialysis system and automatically align the tubing set, sensors, venous drip chamber, and other features with the corresponding components on the dialysis system. Methods of use are also provided, including automated priming sequences, blood return sequences, and dynamic balancing methods for controlling a rate of fluid transfer during different types of dialysis, including hemodialysis, ultrafiltration, and hemodiafiltration.
