From pre-cleaning to sterile packaging
MDR- and FDA-compliant turnkey cleaning solutions for the medical industry
The spectrum of medical products ranges from simple plasters, syringes and cannulas through surgical instruments, implants and pacemakers right up to large machines such as computer and magnetic resonance tomographs (CT and MRT). Depending on type and intended use, the products have to comply to the relevant regulations of the FDA or new European Medical Device regulation (MDR), which became mandatory on 26 May 2021. It has brought about several changes that need to be considered. For example, more products are covered by the regulation, and must be classified in a higher risk category. Furthermore, particulate and filmic contaminations from manufacturing processes must now be considered in addition to bioburden and cytotoxicity values. Traceability and identification requirements have also become stricter. The comprehensive and globally-available range of certified cleaning solutions from the SBS Ecoclean Group enable these requirements to be met in a robust and reproducible manner. Equipped with software solutions specially developed for medical technology applications and RFID technologies, the cleaning and packaging systems provide optimal conditions for equipment certification and process validation according to IQ, OQ and PQ. The inclusion of Audit-Trail and CFR 21 enable automatic acquisition and storage of process data and ensure that all parts and components processed in the systems can be seamlessly traced and identified.
Cleaning - one of the tasks in the production chain
When it comes to components that are manufactured using classic production processes such as machining, forming, extrusion and injection molding, particulate and/or thin-film residues remain on the surface. These residues are usually removed in a pre-cleaning step. For these tasks, the SBS Ecoclean Group supplies modular and customized chamber cleaning systems which use solvents, such as modified alcohols or non-halogenated hydrocarbons, as well as aqueous media (neutral, acidic, alkaline). An intermediate cleaning step that is generally performed after finishing processes such as grinding, blasting or polishing can be carried out efficiently in an aqueous chamber or in-line immersion cleaning system, for example the UCMSmartLine.
In today’s human and dental medicine, additively manufactured components play an ever-more important role in individual patient care. Powder residues from parts produced in powder bed-based printing processes must be cleaned off after unpacking. Dry methods such as vacuum technology can be used to do this, which also enable excess powder to be recovered.
Capillary, lumen or pore structures of geometrically complex components manufactured in sintering or 3D printing processes are especially difficult to clean. For these tasks, multi-stage immersion cleaning systems equipped with multi-frequency ultrasound, injection flood washing and/or pulsated pressure cleaning (PPC) coupled with a suitable medium ensure that contaminants and powder residues are reliably removed from the most delicate structures, narrow lumens and complex geometries.
The final cleaning step is usually carried out in customized in-line immersion cleaning systems, with the appropriate water treatment and cleaning fluid. A passivation step can also be integrated here as necessary. A cleanroom-compatible design of the system or connection to a cleanroom, which is also planned by the companies of the SBS Ecoclean Group, is a further service available on request.
Packaging process included
Regardless of whether the products need sterile or non-sterile packaging after final cleaning, the Group's turnkey solutions also include suitably-adapted machines and equipment. To make sure that production gets off to a quick start, previously designed and validated packaging materials for medical instruments and implants can be used.
Global delivery with local service
The range of turnkey solutions for the medical industry includes the planning, development and manufacture of cleaning systems, as well as interface coordination and implementation. Local service staff not only trains customer employees to operate and maintain the systems; it provides technical support should any queries arise during their operation and also supplies any necessary spare parts. This guarantees maximum availability of the systems and machines.
