There was a time when different medical equipments were used by doctors only and their availability was also restricted to doctors only. However, in modern days there are many such tools that are related to medical science but a common man also uses it with same expertise and hence one can know a lot of things about health without going to a doctor. The fetal Doppler is also one of such machines that can help the users to know the movement of the baby in the womb and know about its health and life. The Doppler is such a device that one can easily use at home and understand the movement of the baby easily.
Fetal Doppler Machine:
This machine is also known as fetal monitoring machine. It is a part of non-invasive diagnostic that can help one check the fetal heart beat and rate. It also helps to measure the heat rate. The mechanism of the Doppler is interesting to know. It uses the ultrasonic waves which human ears cannot hear. The machine emits and receives these waves and on the basis of change of frequency as well as shift of pitch the monitor notes the beat rate. The waves are too sensitive to note even minutest movement in the rhythm also and hence the result of it is considered as accurate also.
This machine was invented by Christian Doppler who was an Austrian physicist and mathematician. The machine works on the principle of varying MGHZ which with the help of piezoelectric crystals note the shortest pulse of sound also and hence it is used to detect the heart beat and rate. The machine sends and receives the waves and as per the emission as well as reception ratio the calculation of the beat rate is done. Many times people get confused with the beat but this is not the actual heartbeat of the baby. It is just a reproduction of the same done by machine.
It is a handy tool these days that one can get from online shop as well as offline one. One can have fetal Doppler buy online from some of the reputed brands also. However, there are a number of features and facts one needs to consider while going to buy it from an online market. One needs to check the quality and price of the machine and compare the same with competitors to get a better deal. One can also go for the reviews of the products provided by the previous shoppers as they have already used the product and it can provide better idea to the new shopper. One can also ask the local expert about the technical aspects of the machine and decide whether to go for it or not.
While going for the offline shopping of such machine also, one needs to check with the brands and go for a little survey before finalizing any deal. The warranty and guarantee, repairing and replacement, extended warranty are also some important features one must consider.
