Invasive blood pressure monitoring system for artificial heart surgery

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.
