Abstract

A mobile dialysis therapy cart includes a top shelf; a cycler compartment positioned below the top shelf, the cycler compartment sized and shaped to house an APD cycler; a fluid bag management compartment sized and shaped to house at least two fluid bags; a drain compartment positioned below the fluid bag management compartment; and a plurality of wheels. The cart may include a heating device associated with the fluid bag management compartment and/or a sanitizing light source for sanitizing a location of a disposable set associated with the fluid bags.

Core Innovation

The invention relates to a mobile dialysis therapy cart that organizes automated peritoneal dialysis (APD) components into a stacked layout. The cart includes a top shelf, a cycler compartment positioned below the top shelf sized and shaped to house an APD cycler, a fluid bag management compartment positioned below the cycler compartment, a drain compartment positioned below the fluid bag management compartment, and a plurality of wheels. The fluid bag management compartment is sized and shaped to house at least two fluid bags and includes a heating device adapted to heat dialysis fluid in one or more of the at least two fluid bags.

The invention also addresses sanitization by integrating sanitizing device functionality into the cart. A sanitizing device can include a sanitizing light source such as UV light and/or an ozone generator that provides ozone-containing gas directed toward specified locations related to disposable-set locations and specific disposable-set features such as solution bag connectors. In this way, sanitization is targeted to particular locations associated with the fluid bag management arrangements and disposable-set interfaces.

In addition, the invention integrates sensor coverage to monitor fluid and material states across the cart compartments. Sensor modules are disclosed for monitoring fluid and/or effluent properties including urea, creatinine, turbidity, and conductivity/sodium concentration, along with sensors for fluid presence/leakage. The system also includes sensing for load/weight, pressure, strain, and level/orientation to provide monitoring related to dosing/volume/flow and cart orientation. Mobility is supported with wheels and battery power, and the document further discloses an optional just-in-time ordering concept based on sensor data.

Claims Coverage

The document provides two independent claims that define a mobile dialysis therapy cart/system with a specific stacked compartment layout on wheels. Across these claims, the main inventive features are the compartmentalized cart structure for APD therapy, the fluid bag management arrangement for at least two fluid bags, the onboard heating device for heating dialysis fluid, and the cart mobility via wheels.

The independent claims focus on a mobile cart/system architecture with a defined stacked compartment arrangement that houses an APD cycler and at least two dialysis fluid bags, where the fluid bag management compartment includes a heating device adapted to heat the dialysis fluid. In the system claim, the APD cycler is explicitly housed within the cycler compartment sized and shaped for the APD cycler, and the cart is characterized by mobility via wheels.
