Fetal
Doppler applies ultrasonic doppler principle to obtain the movement
information of fetal heart from abdomen of pregnant women, enlarge the
signals, and output them from earphones so as to calculate the value of
fetal heart rate.

The LRH biochemical incubator should pay attention to the following points in daily use, so as to avoid unnecessary damage of the incubator and prolong the service life of the incubator to some extent.
(1) The incubator housing should be reliably grounded.
(2) When the biochemical incubator is working in refrigeration, it is not advisable to make the difference between the temperature inside the box and the ambient temperature greater than 25 degrees.
(3) The incubator should be placed in a cool, dry, well-ventilated place away from heat and sunlight. Place it smoothly to prevent noise from occurring.
(4) In order to ensure the effective heat dissipation of the condenser, the distance between the condenser and the wall should be greater than 100mm. The side of the box should have a gap of 50mm, and the top of the box should have at least 300mm space.
(5) During the handling, maintenance and maintenance of the incubator, avoid collision, shaking and shaking; the large inclination of Zui is less than 45 degrees.
(6) The instrument suddenly does not work. Please check whether the fuse tube (after the box) is burnt out and check the power supply.
