2 | amphenol advanced sensors leading edge technology todays patient care demands the ultimate in accurate and reliable monitoring of critical parameters. amphenol is a pioneer in the development of new and increasingly robust sensor technology for medical applications. we offer innovative solutions, fast development cycles and excellent quality control to meet the most stringent requirements. our in-house design and modeling capabilities expedite the process of product development and ensure frst-time success rates for temperature (thermistors and thermopile ir) and gas, humidity and mems-based pressure sensors. we have developed state-of-the-art, high-performance sensors known for their accuracy, reliability and small size. they are used extensively for heart catheters, esophageal stethoscopes, fever thermometers, skin sensors, blood analyzers, incubators, respiration monitors and hypodermic needle sensors. innovative work on small precision sensors continues for cancer research. thermistors measure the temperature of cells and with precise monitoring, doctors can use heat to destroy diseased cells in tumors. healthcare applications ? tympanic temperature ? heart/lung machines ? thermal dilution catheters (heart) ? blood pressure monitors ? urinary catheters ? muscle/bone growth stimulation ? oral, rectal and skin temperature ? sleep apnea ? esophageal catheters ? glucose monitoring ? body mapping ? oxygen tents ? clinical mattresses ? humidifers ? anesthesia ? fluid heaters ? sterilizers ? culture ovens ? cryogenics intercranial pressure catheter oral temperature tympanic temperature thermal dilution catheter (heart) esophageal catheter skin temperature kidney dialysis urinary catheter glucose monitoring muscle/bone growth stimulation rectal temperature
amphenol advanced sensors | 3 although chemical analyzers have been used for many years, we are developing new products that range from large laboratory apparatus to small hand held devices. our sensors monitor oxygen level for critical care and blood chemistry (including glucose, dna and cholesterol), and for diseases such as hiv and cancer. the accuracy and small size of these devices mean that results that took time to process in the laboratory can now be available right at a patients bedside. during dialysis, a patients blood is removed from the body, artifcially fltered by a machine, treated and returned to the body. our ntc thermistor ensures that the blood is reheated to body temperature before it is returned. thermodilution catheters are used extensively in cardiac diagnostic and corrective procedures. tiny ntc thermistors located near the tip of catheters are hermetically sealed in glass and have fne diameter platinum alloy leads welded to insulated extension leads. they are then inserted into hypodermic needles, catheters or other small housings that require extended leads. disposable hypodermic needle sensors are especially critical during open heart surgery, when they are inserted into the myocardium muscle to monitor temperature. hypodermic needle probes with small thermistor beads or chips can be inserted into targeted anatomical sites for temperature measurement and are particularly suited for cancer research and treatment, particularly for brain tumors. disposable pressure sensors are used primarily during surgical procedures and in the icu to monitor patient heart rate and blood pressure. pressure sensors in ventilator machines watch patients with respiratory illness or people on life support, helping control the amount of air pressure delivered to a patients lung. they also monitor people with sleep disorders. during neonatal care, pressure sensors help physicians check the pressure within an expectant mothers uterus. ntc thermistors monitor temperature and air circulation within incubators and skin temperatures of premature babies. our biomedical chip thermistor assemblies are designed for oral or rectal patient temperature monitoring and also for continuous monitoring necessary during induced hypothermia and general anesthesia. ntc thermistor-based digital fever thermometers have replaced glass thermometers as the most widely used method for measuring human body temperature. our reusable probe has a plastic or metal shaft, with the thermistor located in the metal tip. media isolated high pressure sensors medium pressure sensor insulated lead chips
ntc thermistors thermistors are thermally sensitive resistors with either a negative resistance/temperature coeffcient (ntc) or positive resistance/temperature (ptc) coeffcient. amphenol offers a wide range of both types of thermistors from component level through complete assemblies. both types of thermistors are solid state ceramic components, known for their exceptional quality and long life. ntc thermistors are most often used for healthcare devices and are manufactured from the oxides of transition metals and can operate over the range of -196c to 1000c. key characteristics of ntc thermistors ? defned sensitivity to temperature ? sensitivity to electrical power input ? sensitivity to changes in thermal conductivity main applications for ntc thermistors ? temperature measurement and control ? temperature compensation ? surge suppression ? power measurement ? fluid level-fow detection ir sensors thermopile ir temperature and gas sensors and silicon base humidity sensors use micro machining technologies and proven semiconductor manufacturing processes for quality, reliability and price competitiveness. ir sensors are used in applications such as tympanic ear thermometers when an accurate and instant non-contact temperature measurement is needed. key characteristics of ir sensors ? high sensitivity and consistent accuracy ? ultra small size ? fast response time ? low cost ntc thermistors ir sensors main applications for ir sensors ? fever thermometers ? ear thermometers ? non-contact thermometers AAS-BR-165B-03/2014 www.amphenol-sensors.com ? 2014 amphenol corporation. all rights reserved. specifcations are subject to change without notice. other company names and product names used in this document are the registered trademarks or trademarks of their respective owners.
