用于慢性软组织损伤的大功率光谱治疗仪

光谱波段和治疗光强度是光治疗的关键,决定了适应症、治疗深度和疗效。基于水滤红外线A原理,本文采用大功率高效卤素灯为光源,通过对光束整形、密闭液体过滤器以及电子学控制等系统设计了大功率光谱治疗仪,其基本性能与国外先进产品基本相同。该治疗仪的光谱、光功率密度、电气安全性和电磁兼容性通过了医疗器械注册检验,并应用于慢性软织损伤炎症、疼痛的临床治疗中。临床实验结果显示,71例患者在经过(6±1)天治疗后的总有效率达100%,显效率达80.28%,未发生不良反应。该治疗仪提升了有效光谱宽度和治疗光强度,降低了热效应,提高了穿透深度和疗效,有望广泛用于软组织的损伤、慢性炎症、疼痛及伤口愈合等领域。

High-power spectral instrument for chronic soft tissue injury

In the course of phototherapy,the spectral band and therapeutic light intensity are the key fac_tors that determine the indications,therapeutic depth,and curative effect.Based on the principle of waterfiltered infrared A,a high-power halogen lamp was used as the light sourcein this study.A high-power spectral therapeutic apparatus,comprising a beam shaper,a closed liquid filter,and an electronic control system,was designed.Its basic performance was equivalent to those of advanced foreign products.The spectrum,optical power density,electrical safety,and electromagnetic compatibility passed the medical device registration test.The device was used clinically for 71 patients to treat chronic soft tissue injury,inflammation,and pain.After(6±1)days of treatment,the total effective rate is 100%,and the significant efficiency is 80.28%,without adverse reactions being recorded.The therapeutic apparatus improves the effective spectral width and the therapeutic light intensity,reduces the thermal effect,increases the penetration depth and curative effect,and can be widely used in soft tissue injuries,chronic diseases,pain and wound healing.
