The experimental study of intranasal synthetic filter with stent was tried to decrease suspended particulate matter for human respiratory tract. Facial mask or surgical mask were evaluated. Nasal vestibular size in Thai adults was estimated. Different kinds of stents and filters were used. Standard anterior rhinomanometry was the proper objective method to test nasal air flow resistant of stent and filter. Nasal obstructive symptom correlated well with rhinomanometric results. One layer of outer and inner face mask at each end of the cylindrical silicone stent was the suitable device. There were no complications or side effects. This personal protective device was cheap and available. The filtration efficacy should be tested in a general population during a highly air-polluted period.
尝试进行了带支架的鼻内合成过滤器的实验研究，以减少进入人体呼吸道的悬浮颗粒物。对面罩或外科口罩进行了评估。估计了泰国成年人的鼻前庭大小。使用了不同种类的支架和过滤器。标准前鼻测压法是测试支架和过滤器鼻气流阻力的合适客观方法。鼻阻塞症状与鼻测压结果相关性良好。圆柱形硅胶支架两端各有一层内外面罩是合适的装置。没有并发症或副作用。这种个人防护装置价格便宜且容易获得。应在空气污染严重时期对普通人群进行过滤效果测试。
