Abstract
The utility model relates to the technical field of fetus education articles and medical appliances, in particular to a card insertion type multimedia fetus-voice meter with a fetus education function. The existing fetus-voice meter has the problems that the function is single, only the monitoring on the fetal heart of a fetus can be realized, circuit unit resources are wasted and are not fully utilized, the cost is high, and the performance price ratio is low. The card insertion type multimedia fetus-voice meter comprises an ultrasonic Doppler probe, a prepositive magnification unit, a magnification demodulation unit and a pulse formation unit which are sequentially connected, wherein the magnification demodulation unit and the pulse formation unit are respectively connected with a digital signal processing and multimedia audio decoder, a card insertion device and a universal serial bus (USB) interface are arranged on the digital signal processing and multimedia audio decoder, and the digital signal processing and multimedia audio decoder is connected with an audio output unit through the magnification unit. The card insertion type multimedia fetus-voice meter simultaneously has a fetus-voice meter function and a fetus education function and can be connected with a computer for carrying out data exchange, the data quantity is larger, the card insertion device is used, audio files can be selected according to the requirements, and the performance price ratio is high.
Description
Technical field
This utility model relates to fetus education articles for use and technical field of medical instruments, is specifically related to a kind of card insert type multimedia fetus-voice meter with fetus education function.
Background technology
In daily life because fetus is carried out fetal rhythm monitoring, listens to the health status that fetal heart sound can be understood fetus, so the fetal rhythm monitoring, to listen to fetal heart sound be to meet the thing that comes into one's own day by day in baby's the process, so all kinds of fetus-voice meter arises at the historic moment.Common fetus-voice meter generally comprises doppler transducer, pre-amplifier unit, amplification demodulator unit, pulse forming unit, data processing unit and the display unit that joins successively at present, and display unit can show the fetal rhythm rate of fetus.The problem that existing fetus-voice meter exists is: function singleness can only provide the monitoring to the fetus fetal rhythm; The circuit unit wasting of resources fails to be fully utilized, the cost height, and cost performance is low.
Summary of the invention
This utility model will provide a kind of card insert type multimedia fetus-voice meter with fetus education function, to overcome function singleness and the high problem of cost that prior art exists.
In order to overcome the problem that prior art exists, the technical scheme that this utility model provides is: a kind of have a fetus education function card insert type multimedia fetus-voice meter, comprise the ultrasonic Doppler transducer that joins successively, pre-amplifier unit, amplification demodulator unit and pulse forming unit, it is characterized in that: described amplification demodulator unit and pulse forming unit join with Digital Signal Processing and multimedia audio decoder respectively, Digital Signal Processing and multimedia audio decoder are provided with card-inserted device and USB interface, and Digital Signal Processing and multimedia audio decoder join by power amplifier unit and audio output unit.
Above-mentioned Digital Signal Processing and multimedia decoding are that the chip U1 of ATS2501 is a core with the model.
Above-mentioned Digital Signal Processing and multimedia audio decoder and display unit join.
Above-mentioned audio output unit comprises internal magnetic loudspeaker and earphone.
Compared with prior art, the utility model has the advantages that:
1, function is many: owing to adopted more advanced Digital Signal Processing and multimedia decoding unit, therefore all right displaying audio file when the fetal rhythm rate is carried out computing is to carry out fetus education.
2: data volume is bigger: adopt USB interface not only can also be connected with computer and carry out exchanges data battery charge.
3; The cost performance height: used card-inserted device, without the fixed memory chip stores file of reuse, so can not cause the waste of resource, can select audio file according to user's needs simultaneously, the cost performance of entire equipment is increased dramatically.
