Medical Device Sterilization Standards

Hso s standards for the reprocessing and sterilization of reusable medical devices address the safe and effective reprocessing and sterilization of reusable medical devices in health care facilities with the object of achieving an adequate level of sterility assurance and minimizing the risk of injury to the operators of reprocessing and sterilization equipment.

Medical device sterilization standards.

How steam sterilization works. Most medical and surgical devices used in healthcare facilities are made of materials that are heat stable and therefore undergo heat primarily steam sterilization. For the best results sterilization needs to begin with the manufacturers who make use of steam ethylene oxide radiation and other methods to assure the cleanliness of their products long before they are ever brought into use many of these sterilization techniques are addressed. A list of recognized sterilization standards appears at fda s center for devices and radiological health cdrh s web site.

For ethylene oxide sterilization two voluntary consensus standards ansi aami iso 11135 2014 and ansi aami iso 10993 7 2008 r 2012 describe how to develop validate and control ethylene oxide. Please see ansi aami st79 2017 comprehensive guide to steam sterilization and sterility assurance in health care facilities for more information section 3 3 3 1 and annex m. These tests are intended to be performed when defining validating or maintaining a sterilization process.

A consolidation of several previous standards ansi aami st79 2017 offers a comprehensive guide to steam sterilization and sterility assurance in health care facilities. Iso 11737 2 2009 specifies the general criteria for tests of sterility on medical devices that have been exposed to a treatment with the sterilizing agent reduced relative to that anticipated to be used in routine sterilization processing. Also aami tir34 2014 r 2017 water for the reprocessing of medical devices. However compliance to.

Sterile medical device clause 3 20 of iso 13485 2016 states that sterility requirements of each medical device can be subject to applicable regulatory requirements. However since 1950 there has been an increase in medical devices and instruments made of materials e g plastics that require low temperature sterilization. Firms may elect to comply with these standards.
