A kind of measuring device of human respiratory system's function, it includes a respiration measurement devices, when what measures human respiratory system's parameter, user breathes through the respiration measurement device, the respiratory air flow that breathing generates passes through the respiration measurement device, and the respiration measurement device calculates human respiratory system's parameter by signal processing mould group by measuring the related signals such as above-mentioned respiratory air flow measurement, air pressure, temperature, which can show one reception device of what; The utility model has the advantage that 1.Easy structure test user can voluntarily, improves the convenience of lung's detection, can make lung disease patient's early detection relevant issues, early treatment by convenient detection mode; 2.Error using absolute pressure as human respiratory system's parameter is calculated, caused by effectively reducing because of measurement site elevation height.一種人類呼吸系統功能的測量裝置,其包含一呼吸測量裝置,於測量一人類呼吸系統參數時,使用者透過該呼吸測量裝置進行呼吸,呼吸產生的呼吸氣流通過該呼吸測量裝置,而該呼吸測量裝置藉由測量上述呼吸氣流測量、氣壓、溫度等相關訊號,由該訊號處理模組計算出該人類呼吸系統參數,該人類呼吸系統參數可顯示於一接收裝置;本新型具有下列優點:1. 簡易的結構使使用者可自行進行測試,提高肺部檢測的便利性,藉由便利的檢測方式可使肺疾病患者早期發現相關問題,早期治療;2. 以絕對氣壓作為計算人類呼吸系統參數,有效減少因測量地點海拔高度所造成的誤差。
