利用微探头压力换能器技术对猫的声门关闭压及声门关闭时间进行定量分析。9只成年猫用于本实验。全麻下行猫颈正中切口,置入T形气管套管,套管内导入微探头压力换能器,换能器直径约1mm,放置于声门膜部中央,探头下部用5—0尼龙线穿过弹力圆锥系于甲状软骨下缘,便于微探头随声带一起运 Micro-probe pressure transducer technology was used to quantitatively analyze cat’s glottic closing pressure and glottic closing time. Nine adult cats were used in this experiment. Under general anesthesia cat neck incision was cut into the T-shaped tracheal cannula, micro-catheter into the cannula pressure transducer, the transducer diameter of about 1mm, placed in the glottis membrane center, the lower part of the probe with 5-0 nylon thread wear Over the elastic cone on the lower edge of thyroid cartilage, easy micro probe with the vocal cords shipped together
