An automatic electronically operated end-expiratory air sampler has been developed for use in small infants. Upon expiration, which is detected by a hot-wire sensor, a small portion of the end-expiratory air is automatically collected into a syringe mounted on a syringe driver. The sampler obtained 87% of the end-expiratory air sample. Additionally, highly reproducible and consistent results were obtained for the respiratory gases (O2, N2, CO2). The sampler has been applied for studying breath hydrogen excretion to detect lactose malabsorption. It may also be applicable to study other expiratory gases in infants.
已开发出一种自动电子操作的呼气末空气采样器，用于小婴儿。呼气时，通过热线传感器检测到呼气后，一小部分呼气末空气会自动收集到安装在注射器驱动器上的注射器中。该采样器采集到了87%的呼气末空气样本。此外，对于呼吸气体（氧气、氮气、二氧化碳）获得了高度可重复且一致的结果。该采样器已应用于研究呼气氢排泄以检测乳糖吸收不良。它也可能适用于研究婴儿的其他呼出气体。
