Design Of B-mode Ultrasonic Handle Booster Based On Single-chip Microcomputer

With the advancement of science and technology and the integration of medicine and industry,the development of medical equipment has also entered a new stage of automation,intelligence and digitization.In the process of diagnosis and treatment,how to use machines to assist or even replace medical personnel for operations has become a global research hotspot today.In order to solve the problem of wrist strain caused by long-term pressure applied by medical staff during the B-ultrasound detection process,a B-mode ultrasound handle booster based on a single-chip microcomputer is designed as an auxiliary device in the detection process.The purpose is to operate through simple keystrokes.The entire process of applying pressure is replaced by machine automation,which can effectively,safely,easily and accurately complete the entire inspection process.Firstly,the main control structure and scheme of the booster system are determined.The design is based on the single-chip microcomputer,which forms a complete composite control system with the motor drive module,pressure acquisition module,and display module.Select the STM32F103C8T6 chip as the main controller,press the trigger command to the drive module,and control the stepping motor to advance and retreat,thereby driving the B-ultrasound handle to increase or decrease the pressure.The pressure applied during the whole process is collected by a thin-film pressure sensor,and digitally displayed on an OLED display screen after ADC conversion to assist medical staff in making judgments.Secondly,further improve system functions.Set the upper pressure limit to ensure the safety of the control system.When it is detected that the current pressure value exceeds the upper limit,the buzzer and the OLED display warning message will be used to remind the operator at the same time.In order to ensure the flexibility in the operation process,the pressure is controlled by the method of button selection,the use of button selection to control the size of the pressure,you can make more targeted adjustments according to different patients and different detection methods.In order to avoid the waste of detection data,a host computer software based on a computer platform is designed,which can display,collect and save the pressure data collected during the detection process,which is helpful for subsequent research and use.Finally,the test is performed through a combination of software and hardware.The circuit simulation results of the software show that the control system can operate stably under ideal conditions.the physical overlap results of the hardware show that the designed B-ultrasound handle booster can complete the control function in practical applications,the system is safe and stable,and has portability.Simple and flexible,it can effectively reduce the workload of medical staff.
