Medical devices must meet the highest standards in terms of quality and reliability. Doctors, nurses, and patients benefit daily from applications in the field of medical technology that are getting smarter by the day. The use of proven Sensirion sensor solutions contributes to this and offers the possibility of making applications safer, more reliable, and more convenient. Our many years of experience in the field of medical technology make us the preferred experts for leading medical-technology companies.
Our Expertise - Your Benefit
Response times are a decisive performance factor in the medical sector. Our unique CMOSens® technology allows your applications to be controlled with shorter response times than with conventional systems. The response time of a CMOSens® mass flow meter, for example, is less than 1 millisecond, which can be a decisive advantage in a variety of medical applications.
No matter what the application, we know where and how to integrate our sensors for the best results. Our experience with a wide variety of applications in the medical field ensures that the sensors will be implemented properly. Tell us what you need, and we will provide you with optimum sensors.
Our many years of experience in the medical sector make us a valuable partner, offering optimum support for every project in all stages – from the initial concept through the design stage to series production – thanks to our sensor expertise. Ideally you involve us in your project right from the start.
Long-Term Stability, Sensitivity, and Reliability
Our sensors achieve long-term stability, precision, and reliability that are unparalleled on the market. These characteristics are crucial in medical applications, and are fundamental to your and your products’ success.
Economy of Scale
As a standard process for semiconductor manufacturing, CMOS has been optimized for reliable mass production. Through their high-volume production, sensors using CMOSens® technology based on this standard process enable optimum cost-effectiveness – naturally without compromising reliability nor precision.
Sensirion sensor + Fraunhofer micropump = A miniaturized smart drug delivery module
Sensirion and the Fraunhofer Research Institution for Microsystems and Solid State Technologies (EMFT) is presenting an innovative concept study in the field of medical technology.
Fraunhofer EMFT’s silicon micropump has been combined with Sensirion’s LD20 disposable liquid flow sensor as part of a joint project with the aim of developing a smart and cost-efficient miniaturized module for controlled and monitored drug delivery. This highly integrated single-use drug delivery module measures a mere 35 x 15 x 5 mm3.
Efficient Gas Flow Measurements in Bypass
Measuring gas flow in applications requiring high precision and cost-efficiency is a challenge. Experience in recent years has shown that microthermal flow sensors are superior to other technologies. Industries with exacting demands, such as automotive and medical technology, have recognized that microthermal gas flow sensors give their products decisive advantages. These manifest themselves in high long-term stability and precision even when flow rates are minimal, and the sensors’ suitability for cost-efficient and reliable mass production.
Autoclavable Sensors for Medical Applications
Sensirion has been developing and marketing flow metering sensors for many years. Until now, these sensors have been used in ventilation and anesthetic devices to measure the volume of clean air administered to the patient. But apart from this clean tract, both ventilation and anesthetic procedures need a means of metering the flow of exhaled air. This is known as either proximal or expiratory flow metering. In both cases, the sensor comes into contact with air from the patient that is potentially infected with germs and pathogens. These sections of the apparatus are therefore comprised of disposable parts or hygienically sterilizable. Now Sensirion has developed new flow metering devices that are autoclavable and can be washed.
Infusion pumps that sense the drug flow - and even your heartbeat in it
Everyday millions of patients worldwide receive intravenous infusion therapy, many times assisted by a smart infusion pump. Smart infusion pumps provide well-controlled drug delivery over a prolonged period of time and are of tremendous help for hospital staff. However, they fall short when it comes to reliable failure detection. Today’s infusion pumps lack the technology to directly measure the flow rate of the drug inside the tubing which results in two main problems: First, there are failures that remain undetected and, second, over-sensitive pumps generate a high number of false alarms.
Typical failures during infusion therapy include occlusion, air-in-line, free flow, cross-flow in multi-infusion settings, and infiltration or extravasation. While all of the above failure modes are very well known to hospital staff, today’s infusion pumps can at best only detect the first three. Sensirion’s liquid flow sensing technology enables smart infusion pumps to detect not only these failures, but also reverse flow, cross-flow and even infiltration errors reliably.
