Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to the drawings, the present invention provides a technical solution: an ultrasonic fetal heart monitoring device comprises an ultrasonic transducer array, wherein the ultrasonic transducer array is connected with a receiving and transmitting switch, the receiving and transmitting switch is connected with an amplifier A, the amplifier A is connected with an amplifier B, the amplifier B is simultaneously connected with two signal receivers, each of the two signal receivers is connected with an integrator, the two integrators are both connected with a modulus, the modulus is connected with a microprocessor, the microprocessor is simultaneously connected with a delayer and a signal source clock, the delayer is connected with a signal generator, the signal generator is connected with one of the signal receivers, the signal source clock is simultaneously connected with a frequency multiplier and a power amplifier, the frequency multiplier is connected with the signal generator, and the power amplifier is connected with the receiving and transmitting switch.
The amplifier A is a resonance preamplifier. It is a signal that is amplified by a preamplifier, such as a sound signal picked up by a microphone, and needs to be amplified to a certain level before reaching other stages because it is weak. The front-end generally has higher voltage gain and can amplify small signals to a standard level
The amplifier B is a main amplifier.
The signal receiver is a low-voltage differential signal receiver. LVDS technology is used for simple line driver and receiver physical layer devices and more complex interface communication chipsets. The channel link chipset multiplexes and de-multiplexes the slow TTL signal lines to provide a narrow high speed low power LVDS interface. These chipsets may save significant cable and connector costs for the system and may reduce the physical space required for the area occupied by the connectors. The LVDS solution provides a new choice for designers to solve the high speed I/O interface problem.
The delayer is a self-adaptive delayer.
The microprocessor comprises a Bluetooth module and a storage module. The Bluetooth module is used for data interaction with the mobile digital terminal.
The ultrasonic transducer array unit adopted by the device can be independently attached to any position of the abdomen of the pregnant woman, and the digitalization module of the device adopts a low-voltage differential signal acquisition method.
The device not only retains the advantages of the ultrasonic fetal heart monitoring technology, but also improves the sensitivity and the attaching difficulty of the transducer, improves the wearing comfort level, can be used for a very long time in the ultrasonic fetal heart monitoring, and simultaneously reduces the ultrasonic radiation power and the system power consumption.
