Abstract
The utility model provides an ultrasonic Doppler fetal heart voice meter, which comprises a CPU, a main plate, a probe, a power supply and a display screen, wherein CUP signals are connected with the main plate, main plate signals are connected with the probe, display screen signals are connected with the CPU, and the power supply is respectively electrically connected with the CPU, the main plate, the probe and the display screen. The ultrasonic Doppler fetal heart voice meter uses an ultrasonic probe to obtain frequency shifting signals of fetal heartbeat, and accurately analyzes, treats and obtains fetal heart rate without invasion.
Description
Technical field
This utility model relates to the Medical Instruments technical field, particularly a kind of ultrasonic doppler fetal heart sound instrument.
Background technology
The fetal rhythm rate is at present to one of important physical signs of fetal monitoring.The method of obtaining the fetal rhythm rate has: (1) receiver picks up method: the sound wave that vibration produces when utilizing heart of fetus to beat, after the receiver sympathetic response of loudspeaker column, monitor the heart of fetus sound of beating; (2) mike picks up method: mike converts beating of heart of fetus to the signal of telecommunication, and this signal of telecommunication amplifies driving speaker sounding through audio frequency and power amplifier; (3) the fetus electrocardio detects: obtain the fetal rhythm rate by analysis and related algorithm processing to fetal electrocardiogram, preceding two kinds of methods personnel that need guard count acoustic artificial, waste of manpower, and easily because noise and miscount cause erroneous results, real-time is also poor.The third method is owing to be subjected to the interference of parent electrocardiosignal, and the fetus electrocardiosignal is difficult to identification, needs empirical doctor or just can obtain heart rate value more accurately than complicated algorithm.
The utility model content
This utility model provides a kind of frequency shift signal that adopts ultrasonic probe to obtain fetal heartbeat, and analyzing and processing is obtained the ultrasonic doppler fetal heart sound instrument of fetal rhythm rate.
To achieve these goals, this utility model provides following technical scheme:
A kind of ultrasonic doppler fetal heart sound instrument, it comprises: CPU, mainboard, probe, power supply and display screen, wherein said cpu signal connects described mainboard, described mainboard signal connects described probe, described display screen signal connects described CPU, and described power supply is electrically connected described CPU, mainboard, probe and display screen respectively.
Wherein, preferred, described probe is a ultrasonic probe.
Wherein, preferred, described mainboard is provided with digital signal processor and computer interface unit.
By implementing above technical scheme, have following technique effect: ultrasonic doppler fetal heart sound instrument that this utility model provides adopts ultrasonic probe to obtain the frequency shift signal of fetal heartbeat, and analyzing and processing is obtained the fetal rhythm rate and accurately do not had wound.
Description of drawings
The structural representation of the ultrasonic doppler fetal heart sound instrument that Fig. 1 provides for this utility model.
The specific embodiment
In order better to understand the technical solution of the utility model, describe the embodiment that this utility model provides in detail below in conjunction with accompanying drawing.
This utility model provides a kind of ultrasonic doppler fetal heart sound instrument, as shown in Figure 1, this ultrasonic doppler fetal heart sound instrument comprises: CPU 102, mainboard 103, probe 104, power supply 105 and display screen 101, wherein said CPU 102 signals connect described mainboard 103, described mainboard 103 signals connect described probe 104, described display screen 101 signals connect described CPU 102, and described power supply 105 is electrically connected described CPU 102, mainboard 103, probe 104 and display screen 101 respectively.
Wherein, described probe 104 utilizes doppler principle, picks up fetal heart sound signal; Demodulate Doppler signal, and mainboard is delivered in its amplification; Detect the fetal heart sound signal in the Doppler signal
Described CPU is used for using the related algorithm analyzing and processing to obtain the fetal rhythm rate fetal heart sound signal, by mainboard 103 outputs.Perhaps show this fetal rhythm rate etc. by display screen 101.
Described mainboard 103 is used for fetal heart sound signal is amplified, and outputs to CPU 102 and carry out computational analysis and processing, from loudspeaker output, and the demonstration, control, warning etc. that are used for supplemental characteristic.Have digital signal processor and computer interface unit on this mainboard 103, be used for fetal heart sound signal is processed into digital signal, and be used for connecting computer by this computer interface unit.
Wherein, in the present embodiment, preferred, described probe 104 is a ultrasonic probe.Also can pop one's head in for other.
More than a kind of ultrasonic doppler fetal heart sound instrument that this utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to this utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
