国产TJ-1型超声多普勒儿监护仪临床应用鉴定会于1979年10月5日在上海市纺织工业局第二医院召开,参加会议的有上海市科委、市卫生局、中华医学会上海分会、市医学科学技术情报研究站,以及科研单位、医院、学校、工厂等共28个单位,58位代表。国产TJ-1型超率多普勒胎儿监护仪应用2.5兆赫超声多普勒效应,对胎心率作瞬时检测,具有声光显示和电表直读指示,并能测宫缩强度,与胎心率同时进行描记,并能自动报警。本仪器采用广角发射换能器。特殊设计的可变阈值比较器,自动增益控制和信号处理电路,所以仪器
Domestic TJ-1 ultrasound Doppler monitor clinical application of identification will be October 5, 1979 in Shanghai Textile Industry Bureau, the Second Hospital was held to attend the meeting of the Shanghai Municipal Science and Technology Commission, the Municipal Health Bureau, the Chinese Medical Association Shanghai Branch, City Medical Science and Technology Information Research Station, and scientific research units, hospitals, schools, factories and a total of 28 units, 58 representatives. Domestic TJ-1 ultra-rate Doppler fetal monitor 2.5 MHz ultrasonic Doppler effect, the fetal heart rate for instantaneous detection, with sound and light meter and direct reading instructions, and can measure the contractile strength, and fetal heart rate Rate at the same time tracing, and can automatically alarm. The instrument uses wide-angle transmitting transducer. Specially designed variable threshold comparator, automatic gain control and signal processing circuit, so the instrument
