A method includes flowing spent dialysate through a spent dialysate line of a dialysis system into a fluid receptacle fluidly coupled to the spent dialysate line, reacting the spent dialysate with a chemical reagent contained within the fluid receptacle to generate a reacted sample, emitting electromagnetic radiation through the reacted sample using an emitter; detecting a level of one or more waste products present in the spent dialysate using a spectroscopy sensor positioned proximate the fluid receptacle.

A method and a detection device for detecting blood in a dialysate flow of a dialysis machine during extracorporeal blood treatment.

The invention relates to a testing system and related methods for detecting peritonitis or infection in peritoneal dialysate removed from a patient. The testing system can include a fluid sensor apparatus in a fluid line of a peritoneal dialysis cycler through which spent peritoneal dialysate can be pumped. The fluid sensor apparatus can detect one or more markers associated with peritonitis or infection.

A system and method for monitoring the health of dialysis patients with Raman spectroscopy measurements of one or more target analytes is described. The methods include irradiating one or more fluids of interest with light to produce one or more spectrum and detecting the spectrum with a detector. The fluids of interest are preferably those related to dialysis, including hemodialysis and peritoneal dialysis. In a preferred embodiment, the fluids are irradiated with monochromatic light, and one or more Raman spectra are detected as a result of the irradiation. The fluids may be irradiated within the dialysis tubing itself, or removed from the dialysis tubing and irradiated in a separate chamber. The Raman spectra of one or more target analytes of a dialysis patient may be followed over time or compared to one or more reference spectra, thereby providing information on the health of dialysis patients.

A measurement apparatus for a peritoneal dialysis apparatus (10) comprises a connecting means (102), which is in contact with a drain line system (104) of the peritoneal dialysis apparatus (10), and electrochemical sensor means (110). The measurement apparatus (100) receives spent dialysate through the drain line system (104) when the dialysis apparatus (10) is connected with a patient (12). The electrochemical sensor means (110), which is in contact with the spent dialysate, outputs an electric signal in response to contents of urea and glucose of the spent dialysate for data processing and/or data presentation of the electric signal.

The present disclosure is related to a method and system for providing personalised haemodialysis for subject. The method includes obtaining concentration of electrolytes and of metabolic content in blood sample flowing into and out of dialyser through first blood bypass tube and second blood bypass tube, respectively. The first and the second blood bypass tube are arranged in first sensor and second sensor. Similarly, concentration of electrolytes and metabolic content in dialysate fluid flowing into and out of dialyser through first and second dialysate tube, respectively. The first dialysate tube and second dialysate tube are arranged to pass through third sensor and fourth sensor. Further, variations are identified in concentration obtained for electrolytes and metabolic content in blood sample with respect to concentration obtained for electrolytes and metabolic content in dialysate fluid, respectively. Thereafter, removal of electrolytes and metabolic content is performed from blood sample.

A peritoneal dialysis (PD) fluid line set includes a fluid line configured to carry spent dialysate to a drain receptacle and a chemical testing device disposed along the fluid line. The chemical testing device is configured to detect a presence of a substance in the spent dialysate as the spent dialysate flows past the chemical testing device, and the chemical testing device is configured to provide a visual indicator of the presence of the substance in the spent dialysate.

The specification discloses a portable dialysis machine having a detachable controller unit and base unit. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface, a heater in thermal communication with the planar surface, and a sodium sensor in electromagnetic communication with the planar surface. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.

An extracorporeal blood treatment apparatus is provided comprising a filtration unit connected to a blood circuit and to a dialysate circuit, a preparation device for preparing and regulating the composition of the dialysis fluid; a control unit is configured for receiving a desired sodium mass transport at the end of the treatment session and for setting the sodium concentration value for the dialysis fluid in the dialysis supply line at a set point to achieve the desired sodium mass transport at the end of the treatment session.

System and methods for sensing fluid characteristics of peritoneal dialysate infused into and removed from a patient during treatment are provided. The systems and methods can use an optical sensor including a transmitter light source operable to emit light through a fluid flow path and an optical receiver operable to receive at least a portion of the light emitted by the transmitter light source.
