Indications for Use
The Solution Delivery System Local and Solution Delivery System Remote are intended to be used in a hemodialysis facility for mixing and distribution of sodium bicarbonate (bicarb) and the distribution of acid concentrates to remote points of use where they are mixed with purified water to create the dialysate solutions used in hemodialysis. The Acid Delivery System is intended to be used in a hemodialysis facility for the distribution of acid concentrates to remote points of use where they are mixed with bicarb and purified water to create the dialysate solution used in hemodialysis.
Device Story
System provides semi-automatic mixing of bicarbonate concentrate and distribution of bicarbonate and acid concentrates from storage to hemodialysis patient stations. Bicarbonate solution is automatically transferred to an elevated reservoir (head tank). System transfers up to three different acid concentrates from bulk storage (55-gallon drums or larger) to elevated head tanks. Bicarbonate and acid flow via gravity from head tanks to dispensing stations. Used in hemodialysis facilities; operated by clinical staff. Output is the delivery of concentrates to points of use for final dialysate mixing. Facilitates efficient, centralized preparation of dialysate solutions for patient treatment.
Clinical Evidence
Bench testing only; compliance with CAN/CSA C22.2 no. 601-1-M90 and UL std No. 2601-1.
Technological Characteristics
Semi-automatic mixing and gravity-fed distribution system. Includes elevated reservoirs (head tanks) and fluid transfer pumps for concentrates. Complies with CAN/CSA C22.2 no. 601-1-M90 and UL 2601-1 safety standards.
Indications for Use
Indicated for use in hemodialysis facilities to mix and distribute sodium bicarbonate and acid concentrates to patient stations for dialysate preparation.
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.
