The present invention relates to a flushing catheter device, flushing catheter components, and methods for making the same. A flushing catheter includes one or more flush segments comprised of one or more flush ports along a length of catheter body. A preferred method for making a flushing catheter incorporates a retrofit including one or more flush segments. Flushing catheters may be nested within each other's lumens to form a multi-catheter system. Flush segments may enable radial fluid communication between the many lumens and annular lumens of a multi-catheter system, e.g. intraluminal fluid communication. A multi-catheter system including flushing catheters may be entirely purged of air with a single step of fluid injection. A flushing catheter may include a tapered distal end to further enhance the ease of procedure with a multi-catheter system.

A system for purifying incoming fluid is modular and includes a heat exchanger module, an evaporator-condenser module and a compressor. The system components are arranged in a stacked configuration to facilitate gravitational flow of the purified fluid such that the purified fluid drains passively for collection. A system for preparation of ready-to-use treatment fluid includes the modular fluid purification system, a preparation station and a coupling device. The components are configured to be retained in a portable carrier that is manually operable for improved access to and mobility of the components. A coupling device can connect the flow channels of several components and can be used in preparing ready-to-use dialysate. A system prepares a receptacle and a ready-to-use treatment fluid in the receptacle.
