Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bite pad for a composite tongue depressor. Background Technology

[0002] Anesthesiologists need a mouthpiece when performing intubation or placing a fiberoptic laryngoscope. Usually, a simple ring tube is inserted between the teeth in the mouth to perform intraoral operations. Chinese patent CN221578131U discloses a tongue depressor and mouthpiece. The tongue depressor is a blade type. Compared with the commonly used tubular oropharyngeal airway, it can not only effectively prevent the tongue from falling back after insertion into the mouth and improve ventilation, but also occupy less oral space. It can be used for gastroscopy and bronchoscopy at the same time. The ventilation process does not require repeated insertion and removal of the tongue depressor, gastroscopy or bronchoscope. It is convenient to use and has high safety, which can indirectly improve the examination results. However, the mouthpiece requires the patient's mouth to be opened in advance before it is inserted into the patient's mouth. Patients may resist the use of the mouthpiece.
