ANSI/AAMI/RD62-2006 pdf download.Water treatment equipment for hemodialysis applications.
This standard covers devices used to treat water intended for use in the delivery of hemodialysis. Included in the scope of the standard is water used for: (1) the preparation of concentrates from powder at a dialysis facility, (2) the preparation of dialysate, and (3) the reprocessing of dialyzers for multiple uses. The provisions of this standard apply to individual water treatment devices and to water treatment systems assembled from one or more of these devices. In the first instance, this standard is directed at the individual or company that specifies the complete water treatment system and, second, at the vendor who assembles and installs the system. Since systems may be assembled from a number of individual water treatment devices, the provisions of this standard are also directed at the manutacturers of these devices, provided that the manufacturer indicates that the device is intended for use in hemodialysis applications. This standard is wrtten principally to address water treatment systems for dialysis facilties treating multiple patients. However, all of its provisions equally apply to water treatment systems used in applications where a single patient may be treated, such as in a home dialysis or acute hospital dialysis setting, except where stated otherwise. The physician in charge of dialysis has the ultimate responsibility for selecting a water treatment system.
The physician in charge of dialysis also is responsible for maintaining the performance of that system after control of the system has been transferred formally from the installer to the physician. Generally, this transfer takes place ater the installer of the system has demonstrated that the performance of the system meets the requirements of this standard. Recommendations for ongoing monitoring and maintenance of the system are provided in ANSI/AAMI RD52:2004, Dialysate for hemodialysis.
The requirements established by this standard will help protect hemodialysis patients from adverse effects arising from known chemical and microbial contaminants found in water supplies. However, proper dialysis and patient safety is ultimately dependent on the quality of the dialysate. Since the manufacturer of water treatment equipment does not have control over the dialysate, any reference to dialysate in this standard is for clarification only and not a requirement of the manufacturer. The responsibility for assuring that the dialysate is not contaminated, mismatched, or otherwise damaging to the patient rests with the clinical professionals caring for the patient under the supervision of the medical director. Recommendations on the preparation and handling of dialysate in a dialysis facility are provided in ANSI/AAMI RD52:2004, Dialysate for hemodialysis.
1.2 Inclusions The scope of this standard includes all devices, piping, and fttings between the point at which potable water is delivered to the water treatment system and the point of use of the treated water. Examples of components included within the scope of this standard are water treatment devices, on-line water quality monitors (such as conductivity monitors), and piping systems for the distribution of treated water.
Also included in the scope of this standard is the quality of water used to prepare dialysate, to prepare concentrates from powder at a dialysis facility, and to reprocess dialyzers for multiple use.
1.3 Exclusions Excluded from the scope of this standard are dialysate supply systems that proportion water and concentrates to produce dialysate, sorbent dialysate regeneration systems that regenerate and recirculate small volumes of the dialysate, dialysate concentrates, hemdifitration systems, hemofiltration systems, systems that process dialyzers for multiple uses, and peritoneal dialysis systems.
Some of these devices, such as dialysate supply systems and concentrates, are addressed in other American National Standards. Also excluded from the scope of this standard are requirements for the ongoing monitoring of the purity of water used for dialysate, concentrate preparation, or dialyzer reprocessing.
