Abstract:
Objective:To design and analyze a muscle relaxation monitoring system so as to increase the anesthesia efficiency and safety.Methods: The hardware design of system was based on single chip machine (STC89C52RC), and it has the function of LCD real-time display for pressure change and the printing function. The design of software mainly included the system main program design, pressure sensor subroutine, A/D conversion subroutine, LCD real-time display subroutine and printer subroutine, etc.Results:Through the multiple times of test and improvement for the system, the system has achieved stably run, and the pressure value could achieve accurately display between 0-100N.Conclusion: The monitoring system of muscular relaxation has series of advantages, such as simple circuit design, low cost, higher reliability and practicability and so on. It can real-timely and effectively monitor the change of the indexes of muscular relaxation for patients during operation. And the anesthesiologist can effectively control and change medication for patients. In this way, the monitoring system can increase the anesthetic efficiency and decrease the incidence of postoperative residual muscle relaxant.
