Indications for Use
Intended specifically for use in patients with acute or chronic renal failure when conservative therapy is judged to be inadequate. It may also be indicated in the treatment of patients intoxicated with poisons or drugs.
Device Story
CA Cellulose Acetate Hollow Fiber Dialyzers (Models 90, 110, 130, 150) function as hemodialyzers for extracorporeal blood treatment. Device facilitates solute removal and fluid management in patients with renal failure or intoxication. Operated by clinical staff in a hemodialysis setting. Blood flows through hollow fibers; dialysate flows counter-currently to facilitate mass transfer across the semi-permeable membrane. Output is treated blood returned to the patient. Device supports single use or reuse protocols. Clinical benefit includes restoration of electrolyte balance, removal of metabolic waste, and detoxification.
Clinical Evidence
Clinical data collected per FDA Guidance for Hemodialyzer Reuse Labeling. Includes in vivo and in vitro performance data. Bench testing confirms compliance with USP XXI Class VI biological requirements, pyrogen testing (Japanese Pharmacopeia), and particle limits (USP 23 <788> and ASTM F25-68). Sterilization validated per AAMI ST-27.
Technological Characteristics
Hollow fiber dialyzer; cellulose acetate membrane. Sterilized via Ethylene Oxide (EtO) per AAMI ST-27 to SAL 10^-6. Materials meet USP XXI Class VI requirements. Complies with ASTM F25-68 for particle limits. Models 90, 110, 130, 150.
Indications for Use
Indicated for patients with acute or chronic renal failure requiring hemodialysis when conservative therapy is inadequate, and for treatment of drug or poison intoxication. Indicated for single use or reuse on the same patient following specified procedures.
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.
