In one aspect of the invention, a method includes determining an amount of carbon dioxide (CO) in dialysate flowing through a dialysis system using a COsensor associated with the dialysis system, determining, using a pH sensor associated with the dialysis system, a pH level of the dialysate, and calculating a level of bicarbonate in the dialysate based at least in part on the determined amount of COmeasured in the gas and the determined pH level of the dialysate.

Devices for automatic fishing line release during a cast using the acceleration and deceleration of the rod to automatically release the fishing line. In one embodiment, the device is in an under-the-rod position. In another embodiment, the devices is in an over-the-rod position. In other embodiments, the over or under the rod function is determined by manufacturer or user adjustments or changes.

A conductivity detector detects the electrical conductivity of a fluid under analysis for determining chemical or physical properties of the fluid that are related its electrical properties. Such conductivity detectors may find use in, for example, hemodialysis systems for analyzing the effectiveness of the hemodialysis treatment. In an aspect, to improve accuracy of the conductivity measurements, the detector utilizes four-wire resistance measurement methods. In another aspect, to avoid fouling or contamination of the electrodes, the detector utilizes capacitively-coupled contactless conductivity detection (C4D) methods so that the electrodes are physically unconnected to the fluid contained in a fluid chamber. In a possible further aspect, the fluid chamber may be a disposable component removable from the electrodes. The conductivity detector can include other features such as calibration circuits and features for electrically isolating the fluid under detection from the fluid in the rest of the system.

Systems and methods for extracorporeal processing of blood or other body fluid for the treatment of conditions, such as sepsis, autoimmune disease, or toxemia related to kidney failure, liver failure, or drug overdose are provided. In an extracorporeal treatment system, a fraction of a body fluid is passed into a treatment fluid, at least a portion of which is then passed through a sorbent suspension reactor for treatment by a sorbent suspension. The treatment fluid circuit can be maintained at a fixed volume, which enables accurate fluid balance between the patient and the extracorporeal circuit. Some or all of the treatment fluid, optionally also containing nutrients and/or therapeutic agents, is returned to the patient. In a peritoneal dialysis system, dialysate is passed into a patient's peritoneal cavity, recovered from the cavity, passed through a sorbent suspension reactor in accordance with the invention, and returned to the cavity.

A pressurized roller-colloid mill in which the conventional rotor and stator of a colloid mill are preceded by one or more adjustable-thrust roller bearing assemblies disposed in a series relationship. A product to be refined in the form of a slurry is pumped into the feeding port of the mill to pass between the rollers and the inner and outer raceways of one or more roller bearing assemblies, then to the gap between conventional rotor and stator elements of a colloid mill. The multiple rollers and their cooperating raceways constitute working surface areas far in excess of conventional colloid mill rotors and stators. Gang mounting of the rotor of the mill and the inner raceways of the roller bearing assemblies upon a common axially movable shaft permits gap adjustment for the enhancement of milling action. A relief valve at the outlet of the mill cooperates with the adjustable gap to provide an output of product of any desired particle size down to the low micron range.
