Non-invasive Airway Mechanics 傷肺功能檢測，雙腔檢測系統(tǒng)

該系統(tǒng)使用雙腔式體積描記器，對動物的頭部和胸部氣流進行分別測定并計算得出特殊氣道阻力SRaw和特殊氣道導(dǎo)率SGaw?？杉友b霧化給藥系統(tǒng)。

產(chǎn)品主要特點
可同時觀測多只動物，適合長期追蹤的研究；
SRaw和SGaw參數(shù)與有創(chuàng)方式測定的氣道阻力具有高度相關(guān)性；
動物實驗準備較全身體積描記法復(fù)雜；
動物，清醒狀態(tài)下完成測試，無需麻醉；
可加裝霧化給藥模塊；

  The EMMS non-invasive airway mechanics system uses a classic Pennock style double-chamber plethysmograph to measure nasal and thoracic flow. The animal is placed in a double-chamber plethysmograph (eg. PLY 230 for guinea pig), and is restrained in the chamber with a rubber neck collar. This neck collar also provides an airtight seal between the thoracic and nasal chambers. Flow in the two chambers is measured across two pneumotachographs in the plethysmograph wall. A bias flow air supply is used to prevent build-up of CO2 in the plethysmograph, and may also be used to pull aerosol through the nasal chamber.
