A human respiratory system function detecting device comprises a respiratory detecting device detecting a human respiratory system parameter. The respiratory detecting device measures a respiratory flow and an air pressure while a user breaths through respiratory detecting device. A receiving device displays the human respiratory system parameter after a signal processor analyses it. This invention provides a simple structure of the human respiratory system function detecting device for a user to perform a respiratory test by him/herself with few steps. In this invention, an absolute air pressure is used to measure the human respiratory system parameter that is able to reduce detecting errors shown in the prior arts.一種人類呼吸系統功能的測量裝置,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,該呼吸測量裝置藉由測量上述呼吸氣流測量、氣壓等訊號,由該訊號處理模組計算出人類呼吸系統參數,該人類呼吸系統參數顯示於一接收裝置;本發明具有下列優點: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部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。10‧‧‧呼吸罩11‧‧‧罩體12‧‧‧濾膜13‧‧‧濾膜緊壓環15‧‧‧凹面16‧‧‧凸面20‧‧‧呼吸測量裝置21‧‧‧呼吸測量流道24‧‧‧測量模組25‧‧‧訊號處理模組28‧‧‧端塞29‧‧‧節流裝置
