Manufacturers must also control the microbiological load required in their sterilisation process.<\/p>\n<p>The cleaning process set out in ISO 19227 removes impurities left by previous manufacturing stages. It is particularly important to completely remove contaminated components or impurities from surfaces.[\/vc_column_text][vc_empty_space height=&#8221;20px&#8221;][\/vc_column_inner][\/vc_row_inner][\/vc_column][vc_column width=&#8221;1\/4&#8243;][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row&#8221; css=&#8221;.vc_custom_1581513658950{background-color: #ededed !important;}&#8221;][vc_column width=&#8221;1\/4&#8243;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_column_text]\n<h2>Requirements for cleaning methods<\/h2>\n[\/vc_column_text][vc_column_text]Under no circumstances should the chosen cleaning method compromise the performance of orthopaedic implants. Cleaning methods should neither interact with materials nor affect biocompatibility.<\/p>\n<p>In addition, residues of cleaning agents should be properly removed if they are proven to affect the biocompatibility or performance of the implant.[\/vc_column_text][gt3_spacing height=&#8221;25px&#8221;][vc_column_text]<b>ISO 19227 differentiates between the following residues:<\/b><\/p>\n<ul>\n<li>inorganic residues<\/li>\n<li>organic residues<\/li>\n<li>particulate residues<\/li>\n<li>endotoxins<\/li>\n<li>bioburden<\/li>\n<li>cytotoxic residues<\/li>\n<li>visual (visible) residues<\/li>\n<\/ul>\n[\/vc_column_text][vc_empty_space height=&#8221;35px&#8221;][vc_column_text]\n<h2>Cleaning validation<\/h2>\n[\/vc_column_text][vc_column_text]Cleaning validation is used to test the effectiveness of the cleaning process. This process uses accredited methods to analyse the reduction of physical, chemical and microbial contamination.<\/p>\n<p>Both the evaluation and the validation of the cleaning methods require comprehensive knowledge of the manufacturing process to eliminate possible contaminants or material-induced interactions. For example, unwanted interactions can occur when implants are placed in packaging after cleaning.<\/p>\n<p>Consequently, the validation of the cleaning process is interconnected with the biological evaluation of the implant according to ISO 10993-1.[\/vc_column_text][gt3_spacing height=&#8221;35px&#8221;][vc_column_text]\n<h2>Chemical test methods for verifying cleanliness according to ISO 19227<\/h2>\n[\/vc_column_text][vc_column_text]The chosen analytical methods should be applied in a way that allows the cleaning performance at each critical process step as well as during final cleaning to be assessed.<\/p>\n<p>It is therefore essential to have extensive knowledge of the complete production process and any processing aids and materials used in it. This allows possible contamination to be categorised, which significantly reduces the analysis required for validations or re-validations.<\/p>\n<p>Niutec AG uses validated and recognised test methods to identify chemical or physical residues:<\/p>\n<ul>\n<li>A TOC analyser to test for Total Organic Carbon (TOC)<\/li>\n<li>FTIR to check Total Hydrocarbon Content (THC)<\/li>\n<li>Conductivity or ion chromatography (IC) to test for ionic residues<\/li>\n<li>Particle counting and size distribution of particulate residues<\/li>\n<li>Gravimetry to test for particulate residues<\/li>\n<\/ul>\n<p>Using these methods, we can guarantee proof of cleanliness according to ISO 19227.[\/vc_column_text][gt3_spacing height=&#8221;35px&#8221;][vc_column_text]\n<h2>Seminars on the testing of cleanliness of medical of medical devices<\/h2>\n[\/vc_column_text][vc_column_text]\n<ul>\n<li>How do you put ISO 19227 requirements into practice?<\/li>\n<li>How do you adapt internal manufacturing and cleaning processes to these requirements?<\/li>\n<\/ul>\n<p>In our seminars, we examine individual aspects, risks and methods, helping you to implement the requirements professionally and correctly.<\/p>\n<p>Want to learn more?
