Wearable and portable device for recirculating flow dialysis

Abstract

The invention relates to a dialysis device that provides recirculating flow dialysis in a wearable and portable format. It uses an exchangeable purification unit holding a volume of dialysate and/or a sorbent system for the in-situ regeneration of dialysate. The invented dialysis device comprises a carrier that is mounted on a replaceable cartridge. The carrier holds the electronics, user-interface, actuators and sensors. It actuates, controls and monitors the dialysis operation. The cartridge is a replaceable part that is connected to the patient via a flexible tubing. It consists of a reusable housing with a memory chip and holds a disposable inlay containing the purification unit with fluid lines, connectors, dialysate and/or sorbents in combination with a nanofilter. The cartridge is intended for use during the day, as a wearable system. The cartridge can be enlarged with an extension set to offer more capacity. The extended cartridge is intended to be used during the night as a bedside device.
