First, clean thoroughly depending on the material
Always begin cleaning after every use. If you are cleaning hard plastic models, such as basic CPR torsos and dental replicas, use a mild detergent with warm water. Avoid hot water because it can warp the plastic. Use a sponge or soft cloth to gently scrub away stains, such as simulated saliva or blood. Avoid using abrasive brushes that can scratch the surface.
Use a non-alcohol based, gentle cleaner for silicone or rubber (such as soft tissue suturing pad or realistic skin simulators). Silicone can crack if exposed to harsh chemicals like alcohol or acetone. To prevent moisture from building up, wipe gently with a wet cloth and then pat it dry with a lint free towel.
Check if fabric can be removed from models that have fabric parts. If it is removable, wash in cold water using mild detergent, and let air dry. Avoid tumble drying as this shrinks the fabric. If you don't have a mild detergent, use a dampened cloth to clean the stain. Then let it dry.
Avoid getting liquids on electronic components in models that have electronic parts. (For example, high-fidelity CPR with feedback screens and simulated heartbeats). Use a dampened cloth to wipe the surfaces that are not electronic (such as the chest), and a dry one to clean the screens or buttons. These models should never be submerged in water. Liquid can short circuit the internal components.
Second, maintain functional parts
Some medical models contain moving or interactive parts which require extra care. After using models that have simulated channels or tubes (such as IV training arms with fake blood veins), rinse the tubes thoroughly with clean water to remove any simulated fluid or blood. This will prevent clogging. Replace worn parts as soon as possible if the model has replaceable parts, such suturing pads or fake skin layers. Worn inserts will not mimic the real tissue feeling, which makes training less effective.
Remove batteries from battery-powered models if they won't be in use for more than one month. This will prevent battery leakage which can corrode internal components. If necessary, clean the battery compartment with a cotton swab to remove any rust or residue. For models that connect to computers (like laparoscopic simulators), update the software regularly as recommended by the manufacturer--outdated software can cause feedback errors.
Third, store properly to avoid damage
The storage conditions can affect the life expectancy of a model. Avoid direct sunlight, which can fade colors and deteriorate plastic/silicone, and damp places (which encourage mold growth on fabric parts, in particular). If possible, use the original storage case. They're made to fit your model and protect the delicate parts. Use a clean, soft box to store fragile items (like dental models). Wrap them in tissue paper if there is no case.
Avoid stacking heavy objects (like silicone tissue pad) on top of models that are soft. This will cause permanent deformation. Store tall models, such as full-body CPR dolls, upright with support.
Fourth: Regularly check for wear and tear
Models will wear out with time, even if they are stored and cleaned properly. Check for loose or cracked parts, such as a wobbly part on a training set. If you spot small cracks in plastic, use a manufacturer-recommended plastic glue to fix them early--small cracks grow into big ones. Tighten screws slowly to fix loose parts (don't overtighten as this will strip threads). Contact the manufacturer if a part cannot be repaired. Using a model that is damaged can result in incorrect training.
Post-use maintenance of medical models involves cleaning consistently, focusing on functional parts, storing properly, and performing regular checks. These steps will keep models durable and accurate, which ensures effective training over many years.
