Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a medical bite assembly with a multi-directional matching joint and an assembly method thereof. Background Art

[0002] The medical bite assembly is commonly known as a bite device. It is used when a tube needs to be inserted into the patient's mouth. It facilitates the doctor to intubate while ensuring the safety of the tube.

[0003] When the doctor inserts a tube into the patient's mouth, the doctor needs to use a medical bite assembly to support the patient's teeth to ensure that the patient's mouth can always be kept open to facilitate the insertion of the tube. At the same time, in the later treatment process, the medical bite assembly supports the patient's mouth to prevent the tube from being bitten by the teeth and ensure the smooth passage of the tube. However, the existing medical bite assembly has a relatively simple structure, and the tube is fixed by medical tape, which is troublesome to operate, and the use of medical tape will cause an uncomfortable touch to the patient. Furthermore, if the patient needs to insert multiple tubes, more medical tape must be used to fix the tubes, which is very inconvenient. When multiple tubes are inserted into the patient's mouth, there is a lack of matching joints that match the tubes, so that the inserted tubes lack a limiting mechanism, which will cause a certain impact on the tubes that need to be inserted when other tubes are plugged in, and the intubation operation is not carried out.
