Abstract:
The invention relates to a fluid sensor apparatus and a related sensor card for determining and/or monitoring a pH and/or solute concentration in a fluid. The fluid sensor apparatus can be used in any application requiring the detection of fluid components or concentrations of solutes, and in an exemplary embodiment, is used to detect ammonia concentration and/or pH in dialysis fluid. The fluid sensor apparatus has a camera, a light source positioned opposite to the camera, and a receiving slot for positioning a removable sensor card between the camera and the light source such that both sides of the sensor card are exposed to the sampled fluid.
Abstract:
Parallel modules for in-line recharging of sorbent materials using alternate duty cycles for a sorbent cartridge. The sorbent cartridge can have two or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein can be recharged.
Abstract:
Systems and methods of generating a customized dialysate solution are provided. The system and methods use stock concentrates, with the addition of spikes to generate a customized dialysate solution based on the needs of the patient.
Abstract:
Systems and methods of generating peritoneal dialysate are provided. The systems and methods use a water purification module, a sterilization module and concentrates to prepare a bolus of peritoneal dialysate from source water for use with an non-integrated cycler.
Abstract:
The invention relates to an infusate holder for use in dialysis. The infusate holder can include one or more interior compartments for holding infusate containers or infusates. The interior compartments are aligned to cooperate with fluid connectors of a dialysis system, ensuring that the proper infusates are added to the dialysis system at a proper location.
Abstract:
A medical monitoring device for monitoring electrical signals from the body of a subject is described. The medical monitoring device monitors electrical signals originating from a cardiac cycle of the subject and associates each cardiac cycle with a time index. The medical monitoring device applies a forward computational procedure to generate a risk score indicative of hyperkalemia, hypokalemia or arrhythmia of the subject. The medical monitoring device can adjust the forward computational procedure based upon clinical data obtained from the subject.
Abstract:
Control logic and processes for monitoring and controlling sorbent rechargers are presented. The control logic and processes use control systems to monitor the rechargers for performance problems and to control the recharging process. Various sensors in communication with the control systems are provided to ensure proper operation.
Abstract:
A reserve zirconium phosphate module for continuing dialysis in the event the capacity of the original zirconium phosphate module is exceeded. The sorbent cartridge can have a sensor for detecting when the capacity of the zirconium phosphate material has been exceeded, and a valve assembly for diverting the flow of spent dialysate into the reserve module when needed. Any of the modules of the sorbent cartridge can be reusable and the sorbent materials therein recharged.
