  • Publication number: 20240189493
    Abstract: The present disclosure generally relates to a device (200) for detecting infection in a patient (102) undergoing peritoneal dialysis. The device (200) comprises: a housing module (202) removably coupleable to a fluidic element (204) configured for receiving waste dialysate fluid (130) from the patient (102); a set of lighting elements (206) disposed on the housing module (202) and configured for emitting light into the fluidic element (204); a set of optical sensors (208) disposed on the housing module (202) and configured for measuring optical properties of the light that has interacted with the waste dialysate fluid (130) in the fluidic element (204); and a control module configured for measuring turbidity of the waste dialysate fluid (130) based on the optical properties, wherein the dialysate turbidity is indicative of infection in the patient (102) if the dialysate turbidity and historical dialysate turbidity of the patient (102) satisfy a set of predefined conditions.

  • Publication number: 20230256149
    Abstract: The current invention relates to a peritoneal dialysis filter device, which comprises a housing comprising a first port and a second port, and a hollow fibre membrane formed from hollow hydrophilic fibres within the housing. When in use, a dialysate from a subject enters the filter device through the first port and exits via the second port in an outflow direction, and a regenerated dialysate from a sorbent system enters the filter device through the second port and exits via the first port in an inflow direction. Also disclosed herein is a peritoneal dialysis system comprising said filter device, a method for controlling dialysate flow in a peritoneal dialysis system, and a haemodialysis device.

  • Publication number: 20230248890
    Abstract: The present disclosure generally relates to a device for analysing spent peritoneal dialysate from a peritoneal dialysis apparatus. The device comprises: a set of housings attachable to the peritoneal dialysis apparatus; a set of test components disposed in the housings, each test component and comprising one or more reagents for detecting one or more substances; and a set of fluidic conduits connected to the housings for communicating the dialysate from the peritoneal dialysis apparatus to the housings, wherein the test components are arranged for the reagents to react with the dialysate communicated to the housings and thereby detect the substances in the dialysate.

  • Publication number: 20220401634
    Abstract: The invention relates to a sorbent for removing metabolic waste products from a dialysis liquid, the sorbent comprising a soluble source of sodium ions. The sorbent comprises an ion exchange system which converts urea to ammonium ions and which is configured to exchange ammonium ions for predominantly hydrogen ions and to exchange Ca, Mg, and K for predominantly sodium ions. The soluble source of sodium ions overcomes an initial drop in sodium concentration in regenerated dialysate. When used in conjunction with an infusion system configured to utilise exchange of Ca, Mg and K for sodium during dialysate regeneration a desired sodium ion concentration can be maintained.
