Description

Technical Field

[0001] The utility model relates to the technical field of flushing toothbrushes, in particular to an improved flushing toothbrush. Background Art

[0002] The aspirating and rinsing oral care suction tube is used by clinical medical staff to clean and aspirate sputum in the patient's oral cavity and perform oral cleaning and care, such as: patients in a coma, those who have been in bed for a long time, those on mechanical ventilation, those fasting, those unable to eat orally, and those unable to take care of themselves in daily life. It is especially suitable for critically ill patients who have been in bed for a long time and are in a coma.

[0003] In the existing aspirating and rinsing oral care suction tube, a negative pressure chamber is provided inside. One end of the negative pressure chamber is provided with a negative pressure connection port, and the other end is a sputum suction port. A negative pressure adjustment port communicating with the negative pressure chamber is also provided on the aspirating and rinsing oral care suction tube. During use, the operator places a finger on the negative pressure adjustment port. When it is necessary to increase the negative pressure at the sputum suction port, the finger closes the negative pressure adjustment port more to reduce the air entering the negative pressure chamber. When it is necessary to reduce the negative pressure at the sputum suction port, the finger opens the negative pressure adjustment port more to allow more air to enter the negative pressure chamber.

[0004] However, since sputum flows in the negative pressure chamber and the operator's finger presses on the negative pressure adjustment port and directly contacts the negative pressure chamber, it may cause the operator's finger to stick with sputum after use, and may cause contamination when touching other items. Moreover, there are fewer liquid suction holes on the brush head, making it difficult to suck flushing water, saliva or sputum. Content of the Utility Model
