胎儿监护仪一共有三种。
胎儿监护仪？
方法采用临产后胎儿监护仪来监护胎心率。
Methods Certainly, it is a good way to tutelage the fetal heart under monitor.
超声胎儿监护仪宜在孕妇的视线内,并且她也必须要听取有关胎儿的描述。
The ultrasound monitor is put in the patient’s line of sight, and she must also listen to a description of the fetus.
因此，如果你符合这个范畴，那么你可能不需要在整个产程中被要求带上胎儿监护仪。
So if you fit in that category, you probably won't have to be attached to a fetal monitor for the entire duration of your labor.
胎儿监护仪通过测量宫缩时胎心率的反应，从而评估你的宝宝如何处理临产中的压力。
A fetal monitor assesses how your baby is handling the stresses of labor by gauging the response of its heartbeat to the contractions of the uterus.
基于传统的胎儿监护仪功能单一、数据处理手段原始，我们研制了多通道胎儿监护仪。
The methods of traditional fetal monitor are based on linear and statistical analysis, so the multichannel fetal monitor comes forth under the endeavor of our group.
这种胎儿心电监护仪除能象通常胎儿监护仪提供胎心率与宫缩曲线外，还同时能给出胎儿心电图和母亲心率曲线。
This fetal ECG monitor provides not only the tococardiogram (FHR and UC) as a conventional fetal monitor, but also fetal ECG and maternal heart rate records.
当需要更多的准确信息时——比如怀疑发生胎儿窘迫——也许会用到内部监护仪。
When more accurate results are required-such as when there is reason to suspect fetal distress-an internal monitor may be used.
胎儿血氧监护仪与传统的电子监护仪(测胎儿心率，以确定胎儿是否处于应激或缺氧状态)起使用。
Fetal oxygen machines are designed to be used with traditional electronic monitors, which track heart rate to determine whether the fetus is experiencing stress or lacking oxygen.
介绍了一种采用DSP 组成的胎儿心率监护仪的基本结构和工作原理，重点说明了胎儿心率算法的实现。
The paper presents the development and design of an ultrasonic Doppler fetal heart rate monitoring system based on DSP, and explains the realization of a algorithm for detecting fetal heart rate.
Garvin无法说出在美国有多少家医院安装了胎儿血氧监护仪。
Garvin could not say how many fetal oxygen machines are installed in U. s. hospitals.
方法：用胎心监护仪作NST试验，用B超观察FBM、FM、FT、AFV ，该5个指标联合用于监测胎儿宫内状态。
Methods: 5 parameters including NST, FBM, FM, FT, AFV were applied to biophysical score to monitor fetal situation.
在FDA批准18个月后的一则新闻中，Nellcor估计，已经有超过400台监护仪用于约9000名美国胎儿的分娩过程监测。
In a news release 18 months after gaining FDA approval, Nellcor estimated that more than 400 devices have been used to monitor the births of about 9,000 U. s. babies.
