项目摘要

Fetal monitoring at patients' home has been safely and economically launched by utilizing most popular TV game machines, combined with newly developed compact-sized and telemetric fetal monitor, which sends 3 MHz continuous wave (c-w) Doppler signal and simultaneously obtaining the uterine contraction with the pocketable size of 77X57X21 mm, transmitting 55-710 MHz FM waves with the antenna which is simultaneously converted to the lead wire of Doppler signals.By electronically separating the patient's terminal from game machines, safe and inexpensive monitoring has been established. In practical use, after preparing and activating the terminal, patients should simply insert the cassette case into the receptacle of TV game machine, containing FM receiver , A/D converter, additional PROM, clock and other circuits on a compact single board. Fetal rate measurement has been afforded by the continuous calculation of autocorrelation coefficients, with the specially programmed ROM on the board. By these simple procedures, TV machine can be converted into a fetal home monitoring device, continuously designating the fetal heart rate patterns and uterine contractions.Most expensive portion of the system development consists in the programming of software including the translation of complicated data processing software into the specific game machine language. The display of the biomedical data into TV game machine also causes some difficulties in expressing the slow moving fetal heart rate into the specifically moving "game scene" and "characters". Total cost of the system can be estimated minimum and the safety of the patients can be easily assured, even by adding some other functions such as a data-storage, or a bidirectional data-transferring between the patient's home and hospital. As a conclusion, cost effective fetal monitoring system at the patients' home has been established by modifying a Home TV game machine with a telemetric compact front end.

利用最流行的电视游戏机，结合新开发的小型遥测胎儿监护仪，安全经济地开展了患者家中的胎儿监护，该监护仪发送3 MHz连续波（c-w）多普勒信号，同时获得子宫收缩，袖珍尺寸为77 × 57 × 21 mm，用天线发射55-710兆赫的调频波，同时转换成多普勒信号的引线。通过电子分离病人的终端和游戏机，建立了安全和廉价的监测。在实际使用中，患者在准备和激活终端后，只需将盒式磁带盒插入电视游戏机的插座中，在一块紧凑的单板上包含FM接收器、A/D转换器、附加PROM、时钟等电路。胎率测量已经提供了连续计算的自相关系数，与专门编程的ROM上的板。通过这些简单的程序，电视机可以转换成一个胎儿家庭监护设备，连续指定胎儿心率模式和子宫收缩。系统开发中最昂贵的部分包括软件编程，包括将复杂的数据处理软件翻译成特定的游戏机语言。将生物医学数据显示到电视游戏机中，也给将缓慢移动的胎心率表达为特定移动的“游戏场景”和“人物”带来了一定的困难。该系统的总成本可以估计为最低，病人的安全可以很容易地得到保证，甚至通过增加一些其他功能，如数据存储，或双向数据传输之间的病人的家和医院。作为结论，在病人家里的成本效益的胎儿监护系统已经建立了修改家庭电视游戏机与遥测紧凑的前端。
