Invasive Blood Pressure Monitoring System for Artificial Heart Surgery

摘要

Studies of cardiovascular system and cardiac assistance devices are key research direction in our laboratory,a challenging project requires conducting physiological experiments on animal constantly.In an operation,It is significant to detect small changes in important physiological parameters for ensuring the integrity of animal.As a result,in order to detect and acquire accurate parameter variation,a simple monitoring module is quite required as an adjunct to experiments.Directing the widely applied invasive blood pressure monitoring system,a typical block of it is introduced here.Sensor of this system applied has been used in present medical field whose superiorities embody in its continuity,high sensitivity and hygiene.A simulated experiment was established to functionally calibrate the performance of this module to ensure signals can be recorded by the data acquisition system.The result showed a high linear correlationship between pressure and output.That the serial output can be used to interface to a computer for further analysis serves a function as continuous monitor during experiment.
