Abstract

Disclosed are example embodiments of a dialysis machine having a frame, a cartridge cassette, one or more alignment-locking features, and an actuation mechanism. The frame is fixedly coupled to the dialysis machine, and the cassette is slidably coupled to the frame. The cassette can have one or more track structures, with each of the one or more track structures having a rotor and one or more rollers. The one or more alignment-locking features extend from the frame and are configured to be inserted into one or more alignment features of a disposable cartridge that functions to secure or release the disposable cartridge. The actuation mechanism is made to slide the cassette with respect to the one or more track structures.

Core Innovation

The invention relates to a dialysis system that includes a dialysis machine and a disposable cartridge. The dialysis machine includes a frame fixedly coupled to the dialysis machine and a cassette slidably coupled to the frame. The cassette comprises three track structures, and each track structure comprises a rotor and one or more rollers.

The dialysis machine further includes one or more alignment-locking features extending from the frame. The alignment-locking features are configured to be inserted into one or more alignment features of the disposable cartridge, and to secure or release the disposable cartridge. An actuation mechanism is configured to slide the cassette with respect to the one or more track structures and to actuate the one or more alignment-locking features to either secure or release the disposable cartridge.

The disposable cartridge includes a housing having two or more alignment features configured to receive an alignment-locking feature from the dialysis machine. The alignment-locking feature is configured to pull the housing into the dialysis machine and secure the housing. The cartridge further includes first, second, and third tubing lines mounted on the housing, wherein each tubing line comprises a U-shape section configured to fall into a recessed track of the dialysis machine.

Claims Coverage

The identified independent claim defines a dialysis system with a fixedly coupled frame, a movable cassette on three track structures, frame-mounted alignment-locking features for securing or releasing the disposable cartridge, an actuation mechanism for sliding the cassette and actuating the alignment-locking features, and cartridge tubing lines with U-shaped sections that enter recessed tracks.

The claim coverage centers on a reusable dialysis machine frame supporting a cassette that moves on three rotor/roller track structures, while frame-mounted alignment-locking features are actuated to secure or release a disposable cartridge whose housing alignment features receive the locking features and whose tubing lines include U-shaped sections configured to fall into recessed tracks.
