Questions and answers regarding IP Rating in microprocessor knees
IP Rating: Know the difference when it comes to choosing a microprocessor knee
When considering a microprocessor knee, many amputees inquire about the suitability of various prostheses in regard to their work requirements or leisure activities, such as water sports. Below you will find a selection of FAQs regarding particular levels of protection from water/moisture.
An IP rating tells you the level of protection your device has against ingress of solids and liquids. The larger the protection level, the less you have to worry about your prosthesis getting damaged.
If a microprocessor joint is considered weatherproof – how much contact with water or moisture is allowed without damaging the device?
The C-Leg 4 and Genium are considered weatherproof – meaning they can be exposed to rain or splashes of water.
Some water activities involve salt or chlorinated water. Considering this requirement, which microprocessor knee can you recommend?
As the X3 is fully waterproof (with the highest IP rating code) and also corrosion resistant, it meets the needs of those who like to participate in water sports.
After every water-based activity the knee should be rinsed with fresh water and dried.
No, it does not. But the fully waterproof X3 comes with corrosion resistance as an extra benefit.
X3 has the highest possible IP rating in terms of liquid ingress. But how about the joint’s functionality while under water?
When submerged in fresh, salt, or chlorinated water the X3 still offers you full functionality, as it is able to initiate the swing phase even under water. So you can rely on the safety it provides on land while in the water.
