Coil Handling, Storage and Cleaning Tips and Guidelines SIEMENS Healthineers www.siemens-healthineers.us Coil Handling, Storage and Cleaning - Tips and Guidelines Introduction Damaged RF coils are the cause of many costly and time-consuming system issues. Although coils from Siemens Healthcare are manufactured to withstand daily clinical usage, they are precision imaging devices and improper handling can lead to electronic and mechanical coil damage. This document highlights common improper coil handling practices and provides recommendations to ensure maximum coil lifetime. Following these guidelines will help preserve image quality, increase efficiency, reduce parts consumed, and avoid the cost and impact of downtime on patient care. Weekly Coil Setup Check Removable Table with Trolley Removeable table with trolley: pull out and remove all surface coils including “Spine Coil” before connecting the trolley using the electrical connection. The mechanical connection shall only be used in case of emergency. Pins Check coil connectors weekly for bent or damaged pins. Bent, loose, or improperly aligned pins can prevent proper connection between coils and table plugs as well as damage other components in the table (e.g., table sockets), which limits customer scanning. Levers Check coil levers to ensure they open and close fully and properly. Visible Chips/Damage Plug the coils into the table and check to ensure they sit correctly on the table (no gaps, asymmetrical alignment, etc.). 2 Coil Handling, Storage and Cleaning - Tips and Guidelines Do’s Don’ts Do carry coils by the base Don’t carry coils by the upper piece.

We understand accidents do happen; however, coils must be handled carefully and are not developed to withstand excessive forces. The ShockWatch indicator is a device to track forces experienced by coils. It is applied on most of the hardcover coils. In an unlikely event of more force than 100G applied, the ShockWatch indicator will turn red and the coil is no longer covered by the service contract from Siemens Healthineers. Missing shock indicators will be handled as tripped shock indicators. SHOCKWATCH SHOCKWATCH Handin With Cam Impact 1000 030 Tripped shock indicator Intact shock indicator Note: In case the ShockWatch indicator is not tripped but the coil shows signs of misuse like cracked covers or ripped cables, the coil is also no longer covered by the service contract from Siemens Healthineers. 7 Coil Handling, Storage and Cleaning - Tips and Guidelines Cleaning Recommendations This section only contains information for proper cleaning of coils and accessories. Please reference the MR Operator Manual - Coils regarding cleaning and disinfecting coils. Always follow the manufacturer’s instructions. Cleaning RF Coils and Positioning Aids 1. Use commercially available cleaning and disinfectant solutions. 2. Do not pour cleaning fluid onto surfaces and do not spray fluids. Always use a damp cloth for cleaning. 3. Do not immerse in cleaning or disinfectant liquid. Do not rinse with water. The following table lists the classes of active agents that have been tested and are approved. The detergents listed under “not approved” must not be used. Approved Not Approved Aldehydes Alcohol solution (70% isopropyl alcohol and 30% water) – Pads and accessories Quaternary compounds Benzine undiluted Guanidine derivatives Acetone Peroxide compounds Phenols Pyridine derivatives Chloro derivatives Alcohol solution (70% isopropyl alcohol and 30% water) – COILS only Commercially available cleaning agents, detergent substances Alkylamine Organic acids 8 On account of certain regional limitations of sales rights and service availability, we cannot guarantee that all products included in this brochure are available through the Siemens sales organization worldwide.
