An Intelligent Skin Clearing Machine Based On SCM Design

In this paper,an intelligent skin cleaning machine is designed based on the single-chip machine,which can be used in dermatology and surgery to scraping the lesions of skin diseases or burns.The parameters of the cleaning range and speed of the intelligent skin cleaning machine can be set according to the treatment requirements of medical staff and the location,depth and size of the patient’s lesions.Compared with the traditional scalpel,the machine has the following advantages:it is easy and quick,time and labor saving,just set relevant parameters on the touch screen or use the default parameters;it is adaptively adjust the height and depth,automatically adjust the position of the scraper according to the arm distance and pressure feedback;3,monitor the pressure in real time and alarm,and stop working in time when the pressure is too high to prevent injury.This machine reduces the labor intensity of medical staff and also shortens the treatment time of patients,which is of great significance to improve the medical level and patient satisfaction.The five chapters of this article are now being summarized as follows:The first chapter introduces the research purpose and the common clinical cleaning method,and points out that the traditional cleaning tool for skin scraping has time-consuming and laborious problems,difficult control and difficult operation.This paper expounds that the design of intelligent skin cleaning machine can improve the efficiency and quality of dermatology and surgical treatment,and ensure the safety of medical staff and patients.At the same time,through consulting,research literature discovery and market,hospital investigation,there is no relevant product at home and abroad,so the intelligent skin cleaning machine designed in this paper is an innovative product.The second chapter introduces the overall design idea,research method,hardware composition and selection,connection mode and working principle of the intelligent skin cleaning machine.Its main hardware structure includes distance sensor,pressure sensor,motor,clear scraper,and SCM.Two kinds of sensors are mainly introduced:one is the pressure sensor,which adopts the pressure resistance structure and output the electric signal by measuring the resistance changes of the four varistors integrated on the elastic film to reflect the real-time pressure of the clear blade at the patient lesion.The other is the distance sensor,which adopts the infrared principle to output the electric signal by measuring the time interval between the reflection of the emitted light and reflecting the distance from the lesion of the patient.Chapter 3 introduces the research and design of intelligent skin cleaner intelligent control module,the main components of the module is the microcontroller,pressure sensor,distance sensor,the module is responsible for the machine scraping distance setting and real-time monitoring,the distance sensor real-time monitoring data display on the screen,and according to the pressure data collected by the pressure sensor,the module is also responsible for the alarm function of the start and end and the pressure is excessive.This chapter also introduces the technical principle of the single chip computer as the core component of the control module,comparing the advantages and disadvantages of each type of single chip computer and combining with the actual situation of the subject,powerful performance,high quality and low price,development and use of simple STM 32 model and the circuit diagram and circuit board of the control module.This chapter also introduces the hardware design of the sensor data acquisition circuit,using the Wheiss bridge principle to convert the sensor resistance change into the voltage signal,and using a differential amplifier to amplify the voltage signal.This paper analyzes the advantages and disadvantages of the common programming tools and the tools selected according to the actual needs,writes the corresponding program code in C language,and designs the communication interface and protocol between the control module and other components.This chapter also introduces some microcontroller code fragments,which consists of initialization,data acquisition and data display.The initialization part sets some parameters and functions using LCD screen,timer,interrupt,etc.The data acquisition part reads the voltage signal from the sensor every 0.1 seconds and converts it into pressure and distance values.The data display part calls the LCD drive function and displays the pressure and distance values on the LCD screen.Chapter 4 introduces the methods and steps of quality calibration,including boot detection,distance detection,blade movement accuracy detection,noise detection,appearance detection,function detection,etc.,record the detection data and results,using electrical safety analyzer to the machine,to ensure that the machine will not occur in use leakage or electric shock,through physical test verified the function and performance of the control module,and the possible problems and improvement direction are discussed,the final machine smoothly through the test.The fourth chapter introduces the methods and steps of performance verification and calibration quality control of the intelligent skin cleaning machine,including startup detection,distance detection,motion accuracy detection,noise detection,appearance detection,function detection,etc.,and records the detection data and results to calibration and optimize the parameters.The electrical safety analyzer was used to conduct electrical safety testing to ensure that the equipment would not have dangerous leakage or electric shock in use.Finally,the function and performance of the control module were verified through the physical test,and the possible problems and improvement directions were discussed.Chapter 5 summarizes the main research conclusions of the intelligent skin cleaning machine and the problems encountered in the production process,and puts forward the future prospects and further improvement of the performance of the machine and the aspects that need to be improved.At present,the production of the finished machine has been completed,and the hospital clinical trial will be carried out after the approval of the Ethics Committee.Combined with the actual use,the structure and function of the machine will be optimized and the design and improvement will continue.
