The breathing expectoration auxiliary device of this creation offer is continuously blown using one end of what tube body,And then the metal ball body of the tube body other end and linked component is pushed to move back and forth, and position is replied with a spring-assist linked component, weight through metal ball body and interaction venting one's pent-up feelings of exerting oneself, the muscle of respiratory apparatus can be trained and strengthened using the impedance that the weight of metal ball body is formed, and physical vibration is carried out to respiratory tract, air pulsation caused by moving back and forth it, indirectly in throat or the dense phlegm of lung's attachment generates resonance effects, promoting dense phlegm in throat because of resonance auxiliary and expectoration. Furthermore this creation allows user to be apparent that the accurate location of the metal ball body of tubular body using the metal ball body moving condition for the floating piece instruction tubular body for fastening shaft member.本創作提供之呼吸咳痰輔助裝置，其利用於管體的一端連續地吹氣，進而推動管體另一端的金屬球體與連動組件往復移動，並且以一彈簧協助連動組件回復位置，透過金屬球體的重量與用力吐氣的相互作用，可利用金屬球體之重量形成的阻抗來訓練與強化呼吸器官的肌肉，並對呼吸道進行物理性振動，使其往復移動導致的空氣震動，間接對喉嚨內或肺部附著的濃痰產生共振效應，促使喉嚨內的濃痰因為共振輔助而咳出。此外本創作利用扣合軸件的浮片指示管體內部的金屬球體移動狀態，讓使用者可以清楚了解管體內部之金屬球體的確切位置。
