UIC-2018-114 – Direct and Indirect Blood Temperature Sensor

Current body temperature monitoring systems, such as surface, esophageal, or bladder measurements, have various shortcomings, such as difficulty in placement, lack of accuracy, or cause infection. An improved method to continually monitor core temperature with a high degree of accuracy that doesn’t increase risk of infection is needed for monitoring critically ill patients. UIC Researchers have designed a blood temperature sensor via direct and indirect methods Direct Sensor: The concept uses the existing patient arterial line to pull a small amount of blood from the patient into a small sensor chamber in order to take more precise internal body temperature measurement using a non-intrusive method. The temperature is read for about 5 seconds, after which the blood can be returned into the patient through the arterial line Indirect Sensor: This design measures blood temperature through a thermistor encased in a plastic. The temperature reading is based on an algorithm developed by a neural network since the thermistor is reading temperatures indirectly. Hyunjin Kim hkim227@otm.uic.edu 312355-7843
