中心供氧设备在连续不断的供氧过程中，压力一旦超过和低于正常值时，如不及时发现及调整，将对病人的抢救及手术治疗带来影响。为此，我们研制了这种中心供氧压力自动监测装置。当该装置工作时，中心供氧设备的压力超出正常使用范围时，立即发出声、光报警信号，及时提醒有关 In the continuous oxygen supply process of the central oxygen supply equipment, if the pressure exceeds and falls below the normal value, if it is not discovered and adjusted in time, it will affect the patient’s rescue and surgical treatment. For this purpose, we developed this automatic monitoring device for central oxygen supply pressure. When the device is working, when the pressure of the central oxygen supply equipment exceeds the normal use range, sound and light alarm signals are issued immediately to promptly remind the relevant
