Monitor manufacturers of fetal monitoring is the guarantee of maternal and fetal safety, an important means to realize the eugenics, and fetal monitor is one of the most widely used fetal monitoring method is currently used in clinical.

Traditional fetal monitor monitoring probe is connected to the monitor host via a cable, these connecting wire winding to pregnant women brought great inconvenience and discomfort, serious when even pregnant women's psychology and physiology, is not suitable for pregnant women, a long time monitoring and water delivery, such as special cases. And current fetal monitor can realize the monitoring, the electronic monitoring to doctors and work efficiency can be improved effectively.

Wireless fetal monitor with nRF24E1 chip is selected as the core of multi channel wireless communication system, which solves the problems of small volume, low cost and impedance matching. The traditional monitor host conversion into PC and can better achieve fetal physiological information display and file storage storage, printing, and other functions. Fetal monitor has a bellyband, fetal heart monitoring component, a control circuit, a data storage unit, an output interface and a power supply; the number of fetal heart monitoring component is greater than a, uniform fixed in the inner side of the belt; control circuit respectively controls the fetal heart monitoring component, fetal heart monitoring component of the data stored in the data storage unit; data storage unit is connected with the output interface; power to the electrical power supply; the portable fetal heart monitor is convenient to carry, can real-time to the fetus of fetal heart monitoring, improve the monitoring level of the fetal heart and improve the health level of pregnant women, reduce fetal mortality.

The core component of the monitor is positioning device, including fetal heart monitor probe, nylon hook surface, probe protecting nylon net buckle suede, fixing belt buckle, the probe nylon buckle hook surface with a plastic hook, bottom face with a strong adhesive double-sided adhesive, adhesive in the fetal heart rate monitoring instrument probe back. The probe protection nylon net buckle around the pile is also provided with a fixing belt. The beneficial effect is to use protect online nylon buckle and fixing strap monitor probe fixed in the abdomen of a pregnant woman, the probe can not move, while reducing the network protection of abdominal pressure. Compared with the prior art, the existing technology has the advantages of simple structure, convenient use, safety, reliability, etc..
