In medical technology design, engineering and manufacturing, accuracy is everything. Not only are standards and regulations for product quality extremely high in the medical industry, the safety and wellbeing of patients and users depends on it.
Interface continues to provide the medical device and healthcare industry with the most accurate and reliable force measurement products used for R&D, testing, and embedding sensors for continuous measurement.
In our Medical and Healthcare Solutions Overview, Interface dives deeper into our capabilities and product line that is used throughout the lifecycle of development and supply of medical device and healthcare components. For decades, Interface has been a supplier of precision measurement solutions those that are used in the design, engineering, testing and manufacturing of products used in the industry. Here is a quick recap spotlighting why Interface is a preferred industry partner.
Interface Medical and Healthcare Solutions
Interface provides load cells and sensors of all capacities and sizes to use in the development of medical devices, healthcare tools, and technologies that improve the ability to diagnose, mitigate risks, treat illness, support wellness and advance science.
First and foremost, to qualify as a provider of products in the industry the proper certifications for quality are a necessity. Interface is celebrated for meeting and exceeding the quality needs for our customer’s projects in medical and healthcare. Our products are built and tested in accordance with A2LA, International Standard ISO/IEC 17025:2017 and ANSI/NCSL Z540- 1-1994. This accreditation demonstrates technical competence for a defined scope and the operation of a laboratory quality management system.
The next qualification is experience. In the medical industry, they need to know that their suppliers understand their rigid requirements and use cases for their products. Our engineers and product teams have been providing proven sensor technologies used for a wide variety of medical devices, like prosthetics and surgical implements. These products require extremely accurate measurement before they are approved for use. Interface knows what it takes to meet these requirements.
The industry requires a range of capabilities and sizes of measurement devices like our various miniature and shear beam load cell solutions with 10x overload protection. Our torque transducers provide rotary and reactive measurement to accurately measure performance. These solutions are used to control product use, for fatigue testing, test surgical equipment durability, measure implants and monitor equipment. Other Interface medical device and healthcare solutions include multi-axis sensors for multiple channels of measurement in one housing to use in complex designs requiring multiple measurement outputs.
Interface supplies products to test how a prosthetics perform during different positions and stances. The products used in a prosthetic foot design test including the Interface Model 3A120 3-Axis Load Cell, which was installed between the leg socket and the prosthetic foot and the Model 3A120, which was connected to a portable data acquisition system. When standard precision solutions need a custom designed sensor, Interface’s solutions team and engineers work directly with medical device manufacturers to deliver specialized products, systems and software that meet the evolving needs and innovation requirements. Included below is an application note that outlines the prosthetic testing process using Interface force solutions.
In this example, a customer wanted to know how a prosthetic foot responds as it is loaded during different stances. This challenge required a force solution and Interface supplied 3A120 3-Axis Load Cell which were installed between the leg socket and the prosthetic foot. The Model 3A120 was then connected to a portable data acquisition system. With this solution, the customer was able to log data was for the X, Y, and Z axis, review the results and identify premature foot flat and dead spots during foot’s use. Using this data, they’re now able to make improvements to the design. Read more about this prosthetic load and fatigue testing application here.
Stent And Catheter Testing
For this specific use case, large testing rigs that contain approximately a dozen Interface load cells are used to test stents and heart valves that are surgically implanted into patients. The rigs subject the stents and heart valves to thousands of stress tests over months to determine their material properties. Stents stay in a patient’s body for the rest of their life, so accuracy and durability are extremely important. This application makes use of Interface’s Miniature Beam Load Cell product line, which is overload protected. This product line is extremely reliable and has never had a reported fatigue failure. Included below is another application example.
In this application note, the customer needed to apply known forces to stent and catheters to ensure they pass all necessary strength and flexibility testing. Interface’s solution was to use a MBP Overload Protected Beam Miniature Load Cell that is placed behind the guide wire for the stent or catheter. The motor will spin the linear drive and push the load cell and guide the wire through the testing maze. MBP Overload Protected Beam Miniature Load Cell is connected to the DIG-USB PC Interface Module. All forces are measured and stored on PC. Using this system, the Customer was able to perform required testing and log to PC, followed by being able to review results and take actions as needed. You can read more about this application use case for a stent testing system here.
