Application of Schaffner‘s EMC Products in Medical Technology

Posted by Holger Urban

Schaffner’s EMC product portfolio is being integrated with a wide range of medical technology applications

The demographic change creates new tasks and challenges, especially in the area of medicine and medical care. The need for treatment and care as well as the costs of care increase with the age of the patients.  On the one hand, this should lead to a drastic expansion of the hospitals as a consequence, but on the other hand, the declining birth rate reduces the revenue of the medical insurance funds. As a solution to this dilemma, medical supply should be improved in nursing homes, hospice services, palliative care wards, and outpatient nursing services (Keyword: home care). Decentralizing medical care inevitably implies an increasing need of medical devices and appliances, and at the same time, security and reliability of these devices is more crucial and important than ever, as for example, in outpatient care professional medical aid is far away in case of an emergency due to technical defects.

Operating with faulty technical devices puts the life of patients as well as the operating persons in danger. To perform in a riskless, reliable, and hassle-free way, the devices must harmonize perfectly in terms of electromagnetic compatibility (EMC) and must not disturb each other with emissions. This places extremely high demands on EMC. The IEC standard 60601-1, which is obligatory for all medical products, should first of all prevent human injury and, additionally, avoid damage to appliances and devices. To obtain approval in Europe, medical devices must furthermore comply with the obligatory EMC limits set in IEC standard 60601-1-2.

This is where Schaffner’s EMC products come into play. Schaffner’s entire product portfolio is being integrated with a wide range of medical technology applications to secure their EMC: engines and drive systems of compressor units in medical cooling devices as well as conveyor belts in pharmacy robots comprise Schaffner’s single or three phase filters. IEC inlet filters are currently applied in propulsion engines of infusion pumps, and chokes ensure the compliance of EMC limits in processors of displays of varied medical applications and lab scales.

Specialization, Expertise and Long-term Experience

Schaffner FilterSchaffner Group is specialized in electromagnetic compatibility, and additionally has expertise as well as extensive experience collaborating with medical technology. In the course of this collaboration, the existing EMC products have been permanently optimized and adapted to meet the specific requirements of the industry. In addition to the regular EMC products, Schaffner implemented a medical variation (B types) without Y-capacitors The, so that no additional leakage current is introduced into the system through the filter. 

Schaffner Filter_mediznische Versorgung_1pgTo comply with the requirements of the current medical technology and in anticipation of future innovations as well, Schaffner is currently developing a class II filter according to the high requirements and needs of medical technology. Due to its special design, it simplifies the installation in terms of clearance and creepage distances. Additionally, it also prevents any additional leakage current and can therefore be easily installed in devices which need to comply the highest standards.
