【摘要】 鼻咽癌患者放疗后有67%存在吞咽障碍,严重吞咽障碍者表现为饮用呛咳。目前评估吞咽功能的检查方法都是定性检查,不能为治疗提供有效的依据。使用小气压、脉冲气流的刺激,观察室带的内收缩,是目前国际上定量评估喉功能的最先进方式。本文介绍了我院自行研制的吞咽功能脉冲气流测量仪的整体设计和软及硬件结构及原理。更多还原

【Abstract】 67% of the patients with nasopharyngeal carcinoma after radiotherapy have swallowing dysfunction,and some serious patients will be choked when drinking water.The existing assessment methods of swallowing function are all based on the qualitative evaluation,ang can not provide effective bases for the treatment.The most advanced mode to evaluate the laryngeal functions now is: using the stimulation with small air pressure and pulse airflow to observe the internal constriction of plica vestibularis.This paper introduces the overall design,structure of software and hardware and the principle of swallowing function impulse air flow measuring instrument developed in our hospital.更多还原
