Abstract
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.
Claims21
A sensor, comprising:
- a transmitter light source;
- the transmitter light source operable to emit light through a fluid flow path;
- and
- an optical receiver;
- the optical receiver operable to receive at least a portion of the light emitted by the transmitter light source, passing through the fluid flow path,
- wherein the sensor is configured to measure at least one optical parameter of a fluid in the fluid flow path in one or more wavelengths.
3 more elements
A peritoneal dialysis system, comprising:
- a dextrose source fluidly connectable to a peritoneal dialysis fluid generation flow path;
- at least one refractive index sensor;
- a control system;
- the control system programmed to receive a refractive index from the at least one refractive index sensor and to determine a dextrose concentration of a fluid in the peritoneal dialysis fluid generation flow path based on the refractive index.
