Intended Use

The NikkiCart cartridge is indicated for use in patients undergoing extracorporeal bicarbonate hemodialysis for acute renal failure, chronic renal failure, or acute intoxication with dialyzable substances. The NikkiCart cartridge is intended to be used as one component in the preparation of dialysate according to a physician's prescription in a 3-stream proportioning machine on the Nikkiso DBB-06 dialysis system equipped with a compatible bicarbonate cartridge holder.

Device Story

NikkiCart is a single-use polypropylene cartridge containing dry sodium bicarbonate powder; used as a component in hemodialysis. When attached to a Nikkiso DBB-06 dialysis system, the machine draws water through the cartridge to create a saturated sodium bicarbonate solution. This solution is mixed with acid concentrate and water by the machine to produce bicarbonate-based dialysis fluid. Used in clinical settings by healthcare professionals; output is dialysate fluid for extracorporeal treatment. Benefits include enabling on-line preparation of dialysis fluid tailored to physician prescription for renal replacement therapy.

Clinical Evidence

No clinical data. Safety and effectiveness supported by bench testing, including biocompatibility (cytotoxicity, sensitization, irritation, acute systemic toxicity, material-mediated pyrogenicity, hemocompatibility), chemical characterization (chronic systemic toxicity, mutagenicity/carcinogenicity), stability testing (24-month shelf life), and shipping verification per ASTM D4169-16.

Technological Characteristics

Single-use polypropylene (PP) cartridge; contains USP/European Pharmacopeia grade sodium bicarbonate powder. Operates via water flow through the cartridge to create a saturated solution. Designed for 1:44 (45X) acid dilution ratio. Compatible with Nikkiso DBB-06 dialysis system. Sterilization not specified. No electronic or software components.

Indications for Use

Indicated for patients with acute renal failure, chronic renal failure, or acute intoxication with dialyzable substances undergoing extracorporeal bicarbonate hemodialysis.

Regulatory Classification

Identification

A hemodialysis system and accessories is a device that is used as an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and that consists of an extracorporeal blood system, a conventional dialyzer, a dialysate delivery system, and accessories. Blood from a patient flows through the tubing of the extracorporeal blood system and accessories to the blood compartment of the dialyzer, then returns through further tubing of the extracorporeal blood system to the patient. The dialyzer has two compartments that are separated by a semipermeable membrane. While the blood is in the blood compartment, undesirable substances in the blood pass through the semipermeable membrane into the dialysate in the dialysate compartment. The dialysate delivery system controls and monitors the dialysate circulating through the dialysate compartment of the dialyzer.(1) The extracorporeal blood system and accessories consists of tubing, pumps, pressure monitors, air foam or bubble detectors, and alarms to keep blood moving safely from the blood access device and accessories for hemodialysis (§ 876.5540) to the blood compartment of the dialyzer and back to the patient. (2) The conventional dialyzer allows a transfer of water and solutes between the blood and the dialysate through the semipermeable membrane. The semipermeable membrane of the conventional dialyzer has a sufficiently low permeability to water that an ultrafiltration controller is not required to prevent excessive loss of water from the patient's blood. This conventional dialyzer does not include hemodialyzers with the disposable inserts (Kiil type) (§ 876.5830) or dialyzers of high permeability (§ 876.5860). (3) The dialysate delivery system consists of mechanisms that monitor and control the temperature, conductivity, flow rate, and pressure of the dialysate and circulates dialysate through the dialysate compartment of the dialyzer. The dialysate delivery system includes the dialysate concentrate for hemodialysis (liquid or powder) and alarms to indicate abnormal dialysate conditions. This dialysate delivery system does not include the sorbent regenerated dialysate delivery system for hemodialysis (§ 876.5600), the dialysate delivery system of the peritoneal dialysis system and accessories (§ 876.5630), or the controlled dialysate delivery system of the high permeability hemodialysis system § 876.5860). (4) Remote accessories to the hemodialysis system include the unpowered dialysis chair without a scale, the powered dialysis chair without a scale, the dialyzer holder set, dialysis tie gun and ties, and hemodialysis start/stop tray.

# h. Device Description

The NikkiCart is a single use polypropylene (PP) cartridge containing dry sodium bicarbonate powder, which enables on-line preparation of saturated Sodium Bicarbonate solution that, in conjunction with appropriate acid concentrate solution and dialysis water, creates a bicarbonate -based dialysis fluid that meets the Association for the Advancement of Medical Instrumentation (AAMI) guidelines.

When the NikkiCart is attached to the Nikkiso DBB-06 dialysis machine with a compatible bicarbonate cartridge holder, water is drawn by the dialysis machine through the cartridge, producing a saturated solution of sodium bicarbonate. The dialysis machine mixes the sodium bicarbonate solution with water and the acid concentrate to produce a bicarbonate-based dialysis fluid. The acid concentrate must have a dilution ratio of 1:44 also known as 45X to be used with the NikkiCart Sodium Bicarbonate cartridge.

- i. Intended Use
The NikkiCart cartridge is intended for preparation of hemodialysis solutions on theNikkiso dialysis systems. The NikkiCart must always be used with a suitable acid concentrate.

# Indications for Use

The NikkiCart cartridge is indicated for use in patients undergoing extracorporeal bicarbonate hemodialysis for acute renal failure, chronic renal failure, or acute intoxication with dialyzable substances. The NikkiCart cartridge is intended to be used as one component in the preparation of dialysate according to a physician's prescription in a 3-stream proportioning machine on the Nikkiso DBB-06 dialysis system equipped with a compatible bicarbonate cartridge holder.
