摘　　要：目的克服现有临床气囊测压技术中存在的不足，提供一种人工气道气囊在充气过程中的自动压力控制和连续监测的仪器。方法利用单片机进行压力控制，具体结构包括：充气泵、放气阀、压力传感器、CPU、气压稳定腔。结果通过压力传感器控制充气压力，确保人工气道气囊压力在25～30cmH2O的安全范围内。结论实践证明该装置使用便利、安全可靠，压力控制精准，可以临床推广使用。Objective To overcome present deficiencies in manometry technology with clinical balloon by providing an automatic pressure control and monitor device with an artificial airway gasbag. Methods Single- chip microcomputer was used for pressure control, which structure included air pump, valve, pressure sensor, CPU, and pressure stabilizing cavity. Results The pressure was controlled through a pressure sensor to ensure that the artificial airway ballonet pressure stays within a safe range, 25 - 30 cm H2O. Conclusions Practice shows that the device is convenient, safety, reliable, and precisely pressure control. So, It can be promoted in clinical activities.
