Have you heard of the IP rating? It’s an important number that tells how much protection something has against things like water and dust. When doctors prescribe a prosthesis, they sometimes forget to consider the IP rating.
This can be a big mistake because it can end up costing you a lot of money. In this article, I’ll explain why the IP rating is so important and why you shouldn’t ignore it.
Why the IP Rating is Important for Prosthetics
Prosthetics have come a long way in recent years, with advancements in technology allowing for greater functionality and customization. However, one important aspect of prosthetic devices that is often overlooked is the IP rating. IP stands for “Ingress Protection,” and refers to a device’s ability to resist the intrusion of foreign objects like dust and water.
the IP rating is a system used to rate the degree of protection. The International electrotechnical commission (IEC) has developed ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids. The ratings are widely used throughout the industry.
While the IP rating may seem like a technical detail that doesn’t matter much to the average person, it is actually a crucial factor in the functionality and longevity of a prosthetic device.
From providing protection against accidental spills to ensuring the device remains operable in dusty or wet environments, the IP rating plays a vital role in ensuring that prosthetics continue to function optimally over time. Whether you are a prosthetics provider or a patient in need of a prosthetic device, understanding the significance of the IP rating can help to make informed decisions when it comes to selecting the right prosthetic.
Why is IP Rating Important for Prosthetic Devices?
Prosthetic devices are exposed to all sorts of conditions, and it can cause major issues in the long run. Elements like moisture and dust can cause severe damage, leading to corrosion, and short circuits in the case of externally powered systems, or microprocessor prostheses. Moreover, if the patient lives in coastal areas or areas with high rainfall, the chances of corrosion are even higher. In these cases, an IP rating can make all the difference, ensuring that the device continues to function correctly despite the harsh conditions.
IP Rating and Patient Safety
Apart from the device’s functionality, an IP rating also plays a vital role in ensuring patient safety. For example, a short circuit in an externally powered device due to moisture can lead to a severe electric shock to the user. However, if the device has an appropriate IP rating, the risk of electrical hazards is significantly reduced.
Professionals choosing the Right IP Rating while considering a prosthetic device
It’s crucial to choose the right IP rating for prosthetic devices. For instance, if the patient works in a dusty environment, a device with an IP67 rating is recommended. Similarly, if the patient lives in a coastal area or a place with high rainfall, an IP68 rating is recommended.
“After all, it’s not just about the initial investment in a prosthetic limb but also about how long it will last and how well it will continue to perform”
Key Factors to Consider When Evaluating the IP Rating of Prosthetic Devices
The first factor to consider when evaluating the IP rating of a prosthetic device is the level of protection against solid objects. This is the first number in the IP rating, which ranges from 0 to 6. The higher the number, the greater the level of protection. For example, a rating of 6 indicates that the device is completely protected against dust and other solid objects. This is particularly important for amputees who work in dusty or dirty environments.
The second factor is the level of protection against liquids, such as water. This is the second number in the IP rating, which ranges from 0 to 9. The higher the number, the more protected the device is against water and other liquids. For example, a rating of 8 indicates that the device can withstand continuous immersion in water. This is crucial for amputees who want to swim or participate in other water-related activities.
The impact of materials and design on the IP rating
The material plays a crucial role in determining the durability and functionality of the device.
Carbon fiber is a popular material used in prosthetic devices due to its strength, lightweight, and resistance to moisture and corrosion. It is composed of thin, tightly woven carbon fibers that are layered and bonded together with resin. This results in a material that is extremely durable and can withstand a variety of environmental conditions.
Carbon fiber is more resistant to moisture, making it less susceptible to corrosion. Its strength-to-weight ratio is unmatched by most other materials, which means that it can provide a high level of support without adding excess weight to the device.
Example of IP Ratings in Microprocessor Knee (MPK) Units
Let’s explore some of the microprocessor knee units that are currently available in the market and have an IP rating. For the purpose of illustration, let’s focus on one of the leading brands in the industry, Ottobock. Ottobock has a solid reputation for manufacturing high-quality prosthetic devices that are widely used by amputees across the globe.
The first microprocessor knee (MKP) from Ottobock is the X3, which boasts an impressive IP68 rating. According to Ottobock, the X3 has the highest rating of any MKP on the market.
An IP68 rating means that it’s protected from dust, sand, dirt, and water. This is a huge advantage for users, as they can be confident that their prosthetic knee will remain functional and reliable even in harsh environments. Not all MPKs can say that.
What’s more, the X3 is not just water-resistant, but also corrosion-resistant in salt, fresh, and chlorinated water. This is a game-changer, as other MPKs may be okay with temporary submersion or contact with water, but there’s always a risk of corrosion.
An IP68 rating means that the X3 is even protected from that. This makes it an excellent choice for anyone who wants to maintain an active lifestyle without worrying about their prosthetic knee’s durability.
Moving on to Ottobock’s C-Leg 4 and Genium, both of these models are rated at IP67.
An IP67 rating means that they are protected from dust, sand, dirt, and temporary submersion in freshwater. While they may not be as fully protected as the X3, they still offer users peace of mind that their prosthetic knee is built to withstand the elements.
It’s worth noting that not all MPKs can claim to have the same level of durability and reliability that Ottobock’s offerings do. For example, Ottobock’s revolutionary C-Leg has helped over 100,000 users walk confidently in the last 25 years. That’s an impressive track record that speaks to the quality of the product.
Final thought
Prosthetic devices are more than just mere tools for the people who use them, they are a lifeline. For millions of people around the globe, these devices allow them to perform day-to-day tasks with ease and live a more fulfilling life. However, prosthetic devices are exposed to a wide range of harsh environmental conditions, and over time, this exposure can cause serious damage. That’s why selecting the appropriate IP rating for these devices is so important.
An appropriate IP rating can be the difference between a prosthetic device that functions correctly and one that fails due to damage caused by environmental factors. The right rating can protect these devices against moisture, dust, and other environmental elements that could lead to corrosion, short circuits, or other types of damage. With the right IP rating, we can increase the lifespan of prosthetic devices, ensuring that they continue to make a positive impact on the lives of those who rely on them.
As professionals, it is our responsibility to ensure that the prosthetic devices we prescribe function correctly and safely. By choosing the right IP rating, we can protect these devices against harsh environmental conditions, reduce the risk of damage, and increase their lifespan.
We owe it to those who rely on prosthetic devices to do everything, we can to ensure their continued success. So let’s make the right choice and select an appropriate IP rating for prosthetic devices, ensuring that they continue to make a positive impact on the lives of those who need them most.
