摘要： The present invention relates to an optical blood detector system that rapidly detects the presence of blood due to a blood leak in a system. The blood detector system contains a reusable blood sensor that is able to accurately detect the presence of blood in, for example, an extracorporeal blood treatment system by optically sensing light from a sensing region and determining if the light came from a leaked blood. The blood sensor may be responsive to reflected light or light emitted from blood due to bio-fluorescence excited by a light source in the blood detector system. The blood detector system can be placed against absorbent material adjacent to an intravenous needle injection site and quickly detect any blood wicked into the absorbent material. The blood detector system can eliminate the need for medical personnel to continuously inspect numerous patients visually for potentially fatal blood leaks due to needle dislodgement.

摘要： An electrical sensor for sensing electromagnetic properties of process fluids in a dialysis machine or a similar medical device can include a probe for interfacing with the fluids that is made from electronic fabric materials. The electronic fabric probe can include one or more conductors embedded in a non-conductive fabric layer. The electronic fabric probe is accommodated an enclosure which establishes a flow path with respect to the probe to establish fluid contact between the process fluids and the conductors. The conductors can apply or sense current and/or voltage with respect to the fluid. A portion of the electronic fabric probe can be disposed externally of the enclosure to provide electronic communication externally of the enclosure.

摘要： In one aspect, a peritoneal dialysis (PD) machine can be used to detect a heater bag filled with dialysate. The PD machine has a heater tray that includes a temperature sensor and also has a processor that determines a status of the heater bag based on data received from the temperature sensor. For example, the status may be presence of the heater bag on the heater tray and/or correct positioning of the heater bag on the heater tray.

摘要： A valve system is provided that includes an electromechanical solenoid, a gas valve including a magnetic flapper, a power source in electrical communication with the electromechanical solenoid, and a controller. The controller is configured to control the power source to supply an intermediate voltage that causes the electromechanical solenoid to move to a neutral position between a default position and a fully-actuated position. In so doing, the magnetic flapper is maintained in a neutral position between two gas ports and a flow of gas between the ports can be used to clean foreign particles from the magnetic flapper. The controller can also provide a varying voltage to the electromechanical solenoid while in the neutral position to cause vibration of the magnetic flapper and further assist in removing foreign particles. A closed loop system including a feedback circuit can be used for adjusting the voltage applied to the solenoid based on pressure sensed.

摘要： A device for measuring conductivity of a fluid. The device including a chamber and at least two electrodes. The chamber includes an inlet, an outlet, an upper surface, and a lower surface that runs separate from the upper surface. The fluid enters the chamber through the inlet and flows out of the chamber through the outlet. Moving along a length of the chamber from the inlet to the outlet or from the outlet to the inlet, a distance between the upper surface and the lower surface changes in at least one dimension of the chamber. The two electrodes are configured to measure electrical voltage in the fluid that enters the chamber through the inlet and flows out of the chamber through the outlet.
