目的为了降低跳水运动所致视网膜脱离的高发病率,通过研制压力感受器模拟眼,研究不同情况下模拟眼眼压曲线的影响因素,提出眼防护措施。设计实验研究。研究对象内置压力传感器的模拟眼。方法模拟眼由硅胶制成,内置压力传感器,其量程为0~800mmHg,采样频率为512Hz。模拟眼置于模拟头的突出程度分别为-3.5mm、0mm、5mm、10mm,内置模拟眼跳水整体装置的重量分别为6kg、11kg、16kg、26kg。试验跳台为10m、5m、3m。跳水入水角度为正常垂直入水及平拍入水。主要指标模拟眼眼压曲线。结果模拟眼记录的眼压有两个时段,先出现的瞬间冲击压为振荡峰压,后出现的静水压为逐渐上升至平台的曲线。在正常体位入水时,瞬间冲击压总是小于静水压,眼球突出程度对瞬间冲击压无明显影响;随着跳水高度、跳水负重的增加,瞬间冲击压也随之增加。而平拍入水时,在10m跳台、负重16kg,入水瞬间眼压达520mmHg,明显高于静水压。结论跳水入水角度是影响瞬间模拟眼眼压最重要的因素。建议跳水失误时应用手臂护眼,可有效减少眼损害。
Objective To reduce the high incidence of retinal detachment caused by diving exercise and to study the influencing factors of simulated intraocular pressure curve under different conditions by developing pressure receptor simulated eyes and propose eye protection measures. Design experiment research. Study object Built-in pressure sensor simulation eye. Methods The simulated eye was made of silicone with a built-in pressure sensor with a range of 0 to 800 mmHg and a sampling frequency of 512 Hz. The simulated eyes were placed in the simulated head were -3.5mm, 0mm, 5mm, 10mm, built-in artificial eye diving unit weight of the overall device were 6kg, 11kg, 16kg, 26kg. Test platform for the 10m, 5m, 3m. Diving into the water for the normal vertical into the water and into the water flat. The main indicators simulated ocular pressure curve. Results The intraocular pressure recorded by simulated eyes had two time periods. The first instantaneous impact pressure appeared as the peak pressure of oscillation. The hydrostatic pressure appeared later gradually increased to the curve of the platform. In the normal position into the water, the instantaneous impact pressure is always less than the hydrostatic pressure, the extent of eyeball impact on the instant impact pressure has no significant effect; with the diving height, diving load increases, instantaneous impact pressure also increases. The flat into the water, jumping in 10m, load 16kg, instantaneous pressure into the water 520mmHg, significantly higher than the hydrostatic pressure. Conclusion Diving into the water angle is the most important factor that influences the transient intraocular pressure. The proposed application of arm eye protection when diving mistakes, can effectively reduce eye damage.
