The Research On Technology Of Condensation Physical Therapy And Its Clinical Application

Frozen therapy, for the treatment of diseases using liquid nitrogen, frozen knife andcondensate treatment equipment have been extensive applied clinically and achieved greatsuccess, partially because it is easier to operate such therapies. The basic principle is to useultra-low temperature or partially frozen tissues to promote rapid cooling, freezing and thawing,resulting in a series of irreversible damage to achieve the elimination of the lesion tissues.This paper presents a condensed description of physical therapy on the history, theoryfundamentals, refrigeration, freezing methods of research, Condensation physical therapyprinciples and characteristics of specific functions and the application of clinical application for adetailed description of then on the basis of this paragraph portable condensation physical therapyinstrument for the improvement of intelligent condensation physical therapy. Our purpose is tohelp medical doctors to make surgical judgment, to improve the safety and reliability oftherapeutic instruments.Therapy includes thermocouple amplifiers, filters, analog-to-digital converter,microcontroller control modules, liquid crystal display module. Papers detailing the physicaltherapy condensing technology hardware circuit design method and the module of the softwaredesign. C8051F020 system used as a controller, which can achieve the real-time digitaltemperature display and large screen shows the temperature curve movements, treatment time,timing alarm function. That the technology is difficult Ling accurate measurement of how coldthe temperature probe, Thermocouples use the sectional linear fitting method to solve thethermoelectric power and thermocouple temperature between nonlinear problems.Experimental Methods: As a combined method, we performed simulating experiment andmeasure the temperature in actual working environment. The results: The system works well andhas achieved good results in the measurement of temperature in low temperature experiments. Itsactual performance of the main indicators: measuring range:-80℃～+40℃; Resolution:±0.5℃; Error:±1℃. It meets the system requirements of the instrument parameters, simulationand actual measurement values of a certain error and analysis of the main sources of error.The apparatus is simple, easier to operate, low cost, and applicable to gynecology,dermatology, pediatrics, ophthalmology, surgery, dentistry, and thoracic surgery disease.
