半导体激光对动脉血管外照射及血液流量变化学的研究

弱激光对动脉血管外照射及血液流量变化学的研究,是建立在弱激光对血管内照射方法基础上进行的（intravascular low level laser irradiation therapy）ILLLIT。血管内照射是通过低功率氦-氖（He-Ne）激光用光纤导入患者的血管内,直接照射循环血液利用激光的生物效应来实现治疗的一种方法。此种治疗方法对人体无损伤和不良反应,但（He-Ne）氦-氖激光器体积大、对病人的治疗为有创伤治疗和需要一定治疗环境,以至不能广泛地应用于预防治疗和保健治疗。使用血管外激光照射治疗方法是采用与氦-氖激光器波长近似的半导体激光器,采用多点的照射方法贴近皮肤内大血管进行照射,它的特点是体积小、造价低、治疗中可固定,不需要进行有创伤治疗和特定环境等特点,可以广泛地应用在医院及家庭。

Extravascular semiconductor diode irradiation: effects on the blood flow

The effects on the arterial blood flow caused by the low level laser irradiation on the extravascular system are derived from the intravascular low level laser irradiation therapy (ILLLIT), which is performed by introducing the low-power He-Ne laser propagating in an optic fibre.The therapy is done by the optic fibre laser irradiation happened in the circulation system that raises the biological effect in the blood vessels.Though this therapy doesn't show any side effect and it is non-invasive process,however,it is difficult to be broadly used in health and illness protection due to the ponderous He-Ne laser machine and a necessity of professional treatment environment.The idea of extravascular laser therapy is applying a semiconductor laser machine that generates the laser with similar He-Ne laser's wave length to create the irradiation in the trunk blood vessels,which irradiates merely on the surface of the skin.The therapy can be widely used in the hospital and home because the therapy itself is non-invasive and doesn't require any specific environment,in addition,the laser machine is very cheap, handy,and easy to fix during the treatment.
