Saliva is a colorless and thin liquid commonly known as saliva or clam. It has functions of lubricating oral mucosa, dissolving food and facilitating swallowing, and also contains amylase and lysozyme, and has digestion promoting and antibacterial effects. Therefore, saliva is a physiological substance secreted by a human body per se, and the phenomenon that the human body secretes 1000-1500 ml of saliva every day is normal. Patients with swallowing disorder, such as the elderly, patients with cerebral apoplexy and even patients with severe brain injury, have dysphagia, oral fluid flowing and other conditions due to paralysis of facial muscles caused by degeneration or injury of nerves related to swallowing in the brain, and can easily cause coughing and even life danger due to incapability of swallowing independently when lying in bed, or excessive oral fluid flows out from the oral cavity and bacteria easily grow. Saliva detection is an important means for detecting oral diseases in the prior art.
