Indications for Use
Gambro PrismaSate solutions are indicated for use as a dialysate in Continuous Renal Replacement Therapy.
Device Story
PrismaSate solutions are sterile, ready-to-use dialysate fluids packaged in flexible bags. Used in commercially available CRRT machines; physician prescribes specific chemical composition. During therapy, solution is perfused through the dialysis fluid compartment of a hemofilter/dialyzer. Dialysate is separated from patient blood by a semi-permeable membrane; waste products, fluids, and toxins pass from blood into dialysate via diffusion/convection for removal. Therapy aims to normalize blood chemistry in patients with acute renal failure or poisoning. Operated by clinicians in clinical settings.
Clinical Evidence
No clinical data provided; device is a sterile dialysate solution for established CRRT procedures.
Technological Characteristics
Sterile, ready-to-use liquid dialysate solution. Packaged in flexible bags. Chemical composition is prescribed by a physician. Functions via passive diffusion/convection across a semi-permeable membrane in a hemofilter/dialyzer.
Indications for Use
Indicated for use as a dialysate in Continuous Renal Replacement Therapy (CRRT) for the treatment of acute renal failure and other conditions requiring fluid or solute removal, such as drug poisoning with dialysable or filterable substances.
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.
