摘要： This disclosure relates to dialysis systems and methods. In some implementations, a dialysis system includes a dialysis machine with a fluid line and a drain line, a blood line set configured to be connected to the dialysis machine, and a drain apparatus coupled to the dialysis machine. The drain apparatus includes a chamber configured to receive an end of a patient line of the blood line set, an inlet line, an outlet line, and a valve. The inlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the fluid line of the dialysis machine. The outlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the drain line of the dialysis machine. The valve is configured to control flow of fluid through the outlet line.

摘要： A leak detector is provided that is incorporated into the wheels of a moveable medical device and/or cart or cabinet therefor. By incorporating a leak detector into the wheels themselves of the movable medical device, the leak detector, despite movement of the medical device, is suitably located to locate leaks with respect to the medical device at all times and requires no additional setup. The leak detector can further be tested by and interface with the moveable medical device to ensure the leak detector is in working condition and provide a convenient interface for a user. Additionally, by using this technology on each of the multiple wheels of a moveable medical device, the detectable area may be bigger than a leak detector at only one location.

摘要： A detector assembly configured for use in a dialysis (e.g., a hemodialysis) system is disclosed herein. The detector assembly including a wetness detector configured to detect blood, fluid, a leak, etc. The detector assembly being operatively coupled to, and more preferably, including an inertial measurement unit (IMU). Thus arranged, the detector assembly is configured to measure, read, obtain, provide, etc. additional information or data during a dialysis treatment, which information or data can be transmitted and/or used to, for example, provide greater insight into the system and/or to make better decisions. In one embodiment, the detector assembly can be used to determine when and how a patient is moving and feed that information back to the dialysis machine. In use, the information or data can be used in combination with other information to make an improved determination as to the requirement for an alert and/or stoppage of the dialysis treatment.

摘要： A drip chamber is provided that includes a hollow body and a nucleation column extending into the interior of the hollow body or formed on the inner surface of a drip chamber sidewall. The nucleation column can be formed with, or treated by a treatment to include, microfeatures or other surface properties that provide nucleation sites for the nucleation and amalgamation of microbubbles. The drip chamber can include a bubble catcher in the bottom of the hollow body and the nucleation column can extend from the bubble catcher into the interior of the hollow body. Methods of making such drip chambers are also provided.

摘要： A sorbent canister utilized when performing a dialysis treatment during hemodialysis (HD) or peritoneal dialysis (PD) is provided. The sorbent canister includes inlet and outlet ports that include a threaded interface for connection to inlet and outlet tubes for circulation of dialysate through the sorbent canister. Upon disconnection from a dialysis machine, a pressure relief cap can be threaded onto the threaded interface to seal the fluid in the sorbent canister while allowing for off-gases to be expelled when a pressure within the sorbent canister exceeds a threshold pressure, thereby preventing a rupture in the canister body. In one embodiment, the pressure relief cap includes a deformable insert with a hole formed therein that is closed in an uncompressed state and opened in a compressed state. In another embodiment, the pressure relief cap includes a diaphragm that mates with a feature of the inlet or outlet port.

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： A medical wetness sensing device includes a cover, a first and second electrically conductive portions housed in the cover, an electrically insulative portion housed in the cover, and a compressible portion. The cover defines an outer surface. The first and second electrically conductive portions are exposed along an inner surface of the device. The first and second electrically conductive portions are configured to transmit a test signal indicating an absence or presence of a liquid on the inner surface. The electrically insulative portion electrically isolates the first electrically conductive portion from the second electrically conductive portion. The compressible portion is flexible, compressible, and configured such that the inner surface of the device is conformable to skin of a wearer of the device. The compressible portion is formed by at least one of the cover, the first and second electrically conductive portions, and the electrically insulative portion.
