Description

Technical Field

[0001] The utility model relates to the technical field of oral medical treatment, in particular to an oral spherical saliva suction tube. Background Art

[0002] A saliva suction tube (also known as a suction tube or suction tube) is a common auxiliary tool in dental treatment. It is mainly used to clear saliva, blood, water or other liquids from the patient's mouth so that the doctor can see the working area more clearly and perform operations.

[0003] The existing saliva suction tube needs to be placed inside the patient's mouth when in use, and the bottom of the existing saliva suction tube is usually set to a rectangular shape. Such a saliva suction tube is easy to scratch the inside of the patient's mouth when operating inside the patient's mouth. In addition, the operator needs to hold the saliva suction tube for a long time when using it, which can easily cause fatigue. Moreover, the manufacturing material of the saliva suction tube is mostly plastic hose, so if the grip is too strong, it is easy to cause blockage. Therefore, we propose an oral spherical saliva suction tube. Utility Model Content
