基于MSP430的竹夹板固定和石膏托固定的作用力研究

Comparison of the force property between bamboo splint fixation and plaster fixation based on MSP430

目的比较MSP430的竹夹板固定和石膏托固定的作用力。方法本文设计了一款基于MSP430的使用气压闭环的肌肉水肿仿真系统,模拟人体肌肉水肿,通过仿真实验比较竹夹板固定和石膏托固定时肌肉所受压力的情况。结果共进行了15组对比实验,对实验结果求均值后进行二次函数拟合,拟合所得的竹夹板作用力呈较好的线性特性,并且在初始压力相同的情况下竹夹板的作用力衰减速度远远慢于石膏托实验组。结论竹夹板对肌肉的压力更稳固。

Objective To compare the force property between bamboo splint fixation and plaster fixation.Methods A muscular edema simulation system based on MSP430 was designed to carry out experiments.By simulation of human body muscle edema,the pressure on the muscles were compared between the simulation experiment of bamboo splint and plaster fixation.Results A tatol of 15 sets of comparative experiments were carried out.After the experimental,results were averaged,quadratic function fitting was performed.The fitting force of the bamboo plates showed a good linearity.With the same initial pressure,the force of the bamboo plates decrease much slower than plaster group.Conclusion Experiments shows that the force of bamboo splints is more durable and stable for muscles.
