Abstract
A biological availability testing device for simulating a structure of a respiratory system, wherein, including a respiratory pump, a diaphragm, a lung model, alveolar components, an upper respiratory tract, an inhalation component, a mucus replenishment device, a vibration cleaning device, a sealed chamber, a temperature controller of respiratory, a temperature controller of lung. The diaphragm is provided with a one-way valve, the sealed chamber is divided into an upper region and a lower region by the diaphragm. The lung model is connected to the alveolar components, and the lung model and alveolar components are located in the upper region of the sealed chamber. A lung fluid injection/an extraction port of the alveolar component is connected to the sealed chamber. The biological availability testing device has simulated the anatomical structure and physiological functions of the human respiratory system more realistic, and has improved the accuracy and reliability of test results.
