[0002] Sputum scab refers to the solid material formed after the sputum in the oral cavity dries due to the patient's inability to effectively cough out or remove the sputum. This condition is commonly seen in disabled patients in bed, long-term bedridden and lack of exercise leading to reduced saliva secretion, and decreased self-cleaning ability of the oral cavity, making it easy for sputum to accumulate in the tongue, palate and other parts and gradually dry to form sputum scab, especially for patients with cognitive impairment, they often cannot cooperate with routine oral cleaning measures such as brushing teeth and gargling.
[0003] In clinical practice, many disabled patients in bed cannot cooperate with tooth brushing due to cognitive impairment, resulting in a large amount of sputum scab accumulated in their oral cavity, tongue and palate. These sputum scabs not only affect the oral hygiene of the patient, but also can become a breeding ground for bacteria, significantly increasing the risk of lung infection. Disabled patients in bed are prone to form sputum scab in the tongue, palate and other parts due to long-term inability to effectively clean the oral cavity. These deposits not only cause bad breath, but also can cause oral inflammation and other oral diseases. The bacteria in sputum scab can rapidly reproduce in the warm and humid oral environment, further increasing the risk of respiratory tract infection.
