Design of pressure reading system for splinting distal radius fractures
摘要
Abstract
Objective To design a pressure reading system for splinting distal radius fractures to enable real-time monitoring of splint fixation pressure.Methods A pressure reading system for splinting distal radius fractures was developed with the components of a main contrl unit,a pressure and temperature acquisition unit and a power management unit.The main control unit had a STC15 series SCM as the main control chip,and the pressure and temperature acquisition unit was realized with a FSR400 thin film pressure sensor and a DS18B20 digital temperature measurement chip.The software of the system was developed with C language.The system developed was used to test the magnitude and distribution of the pressure on the splints by applying loads on the fixation straps at 90°,60° and 30° directions to the willow splint and 3D printing splint,respectively,with the total mass of the loads increased from 600 g to 1 200 g and each test repeated by 6 times.Results The system developed was capable of collecting the pressure values at real time and showed them on the display screen.The maximum pressure always occurred at the the connection between the fixation straps and the edge of the splints and the middle parts of the splints were subject to relatively low pressure in case of different loads,when the fixation straps were 90°,60° and 30° to the willow splint and 3D printing splint respectively.The maximum pressure on the willow splint was(239.17±4.49)g when the fixation strap was 90° to the splint and loaded with 1 200 g;the minimum pressure on the willow splint was(89.83±17.38)g when the fixation strap was 60° to the splint and loaded with 600 g.The maximum pressure on the 3D printing splint was(177.67±21.77)g when the fixation strap was 90° to the splint and loaded with 1 100 g;the minimum pressure was(66.50±3.02)g for the 3D printing splint when the fixation strap was 30° to the splint and loaded with 600 g.Conclusion The ssystem developed can read pressure values of the splint under different loads and angles,and the 3D printing splint behaves better than the willow splint in the evenness of pressure distribution.Theoretical references are provided for quantitative clinical treatment with splint fixation.[Chinese Medical Equipment Journal,2024,45(8):44-50]关键词
