Automatic counting device for fetal movement

Technical Field

The invention relates to a medical appliance, more specifically it is a kind of the soil for detecting and recording automatic counting device for fetal movement.

Background Art

Pregnancy mitsuru 4 months later, in other words from the section 5 month precursor can be clearly felt that the activities of the fetus, reach the fetus in the uterus, kicking, impact uterine wall, that is moveable. The number of the number of times for fetal movement, said speed or the safety of the fetus. Normal obviously quickening 1 hours of not less than 3-5 time, 12 hours times as fetal movement obviously 30-40 or more times. However, due to large individual difference of a fetus, some fetal 12 hours movable 100 times the left and right, as long as the regular extractor, a rhythm, does not change much, that is, showing that fetal development is normal. Fetal movement normal, said good function of placenta, adequate oxygen delivery to the fetus, fetal growth and development of the sound in the uterus, the activities very pleasant.

When the pregnant women found that the soil 12 hours less than 20 times, every hours or less than 3 times, indicates the fetal hypoxia, may be subject to serious threat to life. The initial stage of the oxygen, will increase the number of times for fetal movement, because of the lack of oxygen, fetal dysphorias. When the intrauterine fetal hypoxia continue to increase, gradually for fetal movement, the number of times to reduce, at this moment the fetal dangerous harbingers. If do not take appropriate rescue measures, there will be a fetus fetal movement disappears, and even the fetal dematerialised, asystole and death. This process about 12-48 hours. Abnormal fetal movement once it is discovered that pregnant women therefore, must not be lightly, for should immediately to midwifery, timely treatment, often dialogist view.

Observation quickening preferably every morning, noon, evening, a, for each successive counting 1 hour, then the 3 and multiplied by the count of 4 can be projections 12 hours times for fetal movement.

The current method for detecting fetal movement of pregnant women themselves mainly depends on the counting, subjectivity is relatively strong, counting is not accurate, the unreliable.

Content of the invention

The purpose of this invention is to provide a convenient to carry, easy to use, can be operated by non-medical personnel of the automatic counting device for fetal movement, the invention can at any time and any place the monitoring of the number of a pregnant woman, can be by the way of wireless transmission to transfer the information to the health care staff or family, quickening the number of times on the display screen, and immediate notification pregnant women, if lower than the number of audible and visual alarm will be carried out immediately.

In order to achieve the above-mentioned purpose, this invention adopts the following design scheme: a quickening automatic counting device, comprises a host computer, sensor, belt and a wireless receiver, the host comprises a circuit board, a battery, a power switch, a wireless transmitting module, a low-voltage indicator light and working state indicating lamp; the sensor is the pressure sensor and the sensor wire; the wireless receiver comprises a wireless receiving module, display, a sound alarm circuit, light alarm circuit, battery and a power supply switch; said pressure sensor is connected with the host computer through the sensor wire; the host through wireless signal transmission mode of the data transmission to the wireless receiver. The host circuit board is composed of a pressure counter module, a constant current circuit, low voltage indicating circuit and wireless transmitting module; said pressure counter module and a signal input end of the signal of the pressure sensor is connected with the output end of the; pressure counter module to the signal output terminal is connected with the wireless transmitting module, pressure counter module of the another signal output end is connected with the low voltage indicating circuit; said constant current circuit is a pressure sensor to provide a constant current power supply. The wireless transmission module is made up of signal digital encryption circuit, a modulation circuit and a power amplifier circuit. The wireless receiving module is composed of a high-frequency amplifier circuit, a mixer circuit, modulation-demodulation circuit, the decryption circuit and a driving circuit; low-voltage detection circuit, sound reminding circuit, light indicating circuit is connected with the drive circuit. The pressure sensor is arranged in the one elastic body, additional soft absorbed by the shield, in the belt.

To summarize the above, the advantage of this invention is to: automatically records the quickening of the digital, objective and accurate results, quickening is abnormal immediately alarm, the pregnant medical treatment in a timely manner, which greatly reduces the risk of intrauterus the embryo dies.
