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.
Challenges in Personalized Medicine
Modern medicine has been able to drastically improve the quality of life of the global population. Diseases such as polio, syphilis, tuberculosis or the plague have been almost eradicated and are successfully treatable or curable. The next milestone for modern medicine is personalized medicine. This novel discipline does not target the broad population, but focuses on the individual for the diagnosis and beyond. Personalized medicine takes the individual’s disease pattern, the patient’s constitution and gender and the resulting implications for the therapies and medicines into account. The overall goal is to create a therapy tailored to the individual that can, if necessary, be adjusted and fine-tuned according to the disease progression.
Yet Another Technical Gap Closed: Measuring Lowest Flow Rates in Medical Therapies
Medical procedures and therapies are often faced by the same challenge: accurately measuring and controlling lowest flow rates down to the microliter per hour range. In most of these cases the outcome of the therapy, as well as the well-being or even the survival of the patient strongly rely on the reliable and continuous drug administration in such low flow regimes. While various countermeasures have been evaluated and introduced, there is still room for improvement and for new technologies to be established. One novel development with tremendous potential is a single-use liquid flow sensor that is able to measure lowest flow rates and detect common failure modes quickly and reliably.
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.
Single-Use Proximal Flow Sensors
In the past, the decision to opt for a particular flow sensing technology in respirators and ventilation devices was a painstaking and complex process. More recently, however, we have seen the emergence of flow sensor solutions that provide a fully calibrated and temperature-compensated output signal. Proximal flow sensors are widely used in respiratory devices for intubated patients and non-invasive ventilation patients in hospitals, home care situations and emergency rooms. With applications ranging from neonatal to adult care, the associated requirements for proximal flow sensors are both diverse and challenging. Sensors must be reliable and cost-effective while offering long-term stability – in addition to a host of other characteristics. Proximal flow sensors also have particularly high requirements with regard to hygienic sterilization due to the patient’s contact with air, which can potentially be infected with pathogens.
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.
