[0026] Figure 5 It is a block diagram of the circuit block diagram of the integrated ultrasonic bone densitometer with airbag of the present invention.

[0027] Please continue to see Figure 5 In the integrated ultrasonic bone densitometer provided by the present invention, an airbag 9 is provided on the cylinder, and the airbag 9 is connected to the ultrasonic probe 1 through a guide rail mechanism, and the ultrasonic probe 1 is connected to a distance measuring device 12, and the distance measuring The device 12 may be a displacement sensor or a laser rangefinder. The airbag 9 is provided with a pressure sensor 11, the input end of the drive controller 2 is connected with a displacement sensor or a laser rangefinder to detect displacement data, and is connected with the pressure sensor 11 to detect airbag pressure. The output end is connected to the airbag 9 through the air pump controller 10 to control the inflation and deflation of the airbag 9. The drive controller 2 can select an Atmega64 single-chip computer to complete the real-time control of the instrument. The Atmega64 single-chip computer is connected to the tablet computer 3 through a USB interface, such as an ARM11 tablet computer. The ATmega64 single-chip microcomputer control board is used to receive commands from the ARM11 tablet computer and send control commands to the ultrasound probe; the ARM11 tablet computer is used for medical record writing and human-machine interface interaction, data calculation, data storage, and measurement result display; The embedded printer 4 is used to print the text and graphics of the measurement result parameters.

[0028] In the integrated ultrasonic bone densitometer provided by the present invention, the ultrasonic probe 1 is provided with an ultrasonic transmitting signal generating circuit and an ultrasonic signal receiving circuit, and the driving controller 2 is provided with an A/D converter and a signal amplifier. The input end of the A/D converter is connected with the ultrasonic signal receiving circuit, and the output end is connected with the tablet computer 3 through the USB interface. The ultrasonic probe driving mechanism is used to automatically move the probe closer to the calcaneus to be measured, and the ultrasonic probe 1 is used to transmit ultrasonic pulses and receive ultrasonic signals passing through the calcaneus.

[0029] The measurement and use of the integrated ultrasonic bone densitometer provided by the present invention is as follows: First, input medical record information on the virtual keyboard of the operating tablet 3, and then click the measurement menu to issue a measurement command. The measurement command is sent by the CPU of the tablet 3 to the ATmega64 microcontroller control board through the USB interface. After the ATmega64 microcontroller parses the command, the inflatable relay is turned on. The airbag inflates and pushes the receiving and sending probe closer to the middle of the calcaneus, and the probe is pressed against the back of the calcaneus. The probe transmits ultrasound, and part of the ultrasound passes through the calcaneus to the receiving probe on the other side, see figure 2 Shown. The ATmega64 single-chip microcomputer control board receives the attenuated ultrasound and amplifies it. After A/D conversion, it is sent back to the ARM11 tablet through the USB interface. The bone density analysis and calculation software running in the Android4.2 environment processes the received data. The processing result is displayed on the screen in the form of graphics and parameters, or output by a micro printer 4. The doctor's diagnosis conclusion can be input with the touch screen, and the medical record data can be stored in the ARM11 tablet. After the measurement, the operating doctor enters the end command on the virtual keyboard of the tablet computer 3. The end command is sent by the CPU of the tablet computer 3 to the ATmega64 microcontroller control board through the USB interface. After the ATmega64 microcontroller parses the command, the inflatable relay is disconnected, and the airbag is deflated to drive the transceiver. The probe is retracted to its position on both sides.

[0030] In summary, the integrated ultrasonic bone densitometer provided by the present invention integrates the tablet computer 3, the color printer 4, the ultrasonic probe 1 and the drive controller 2 into the frame 8 of the embedded structure to complete the ultrasonic signal detection , Analyze, process and print the diagnostic report, simple structure, easy to operate and use, the specific advantages are as follows: 1. Small size, low site requirements; 2. Easy to transport; 3. Low power consumption; 4. Touch screen operation, no keyboard required Mouse; 5. Open source Android operating system, no copyright fees; 6. ARM tablet computer cost lower than X86 desktop computer.
