Description

A gastroscope mouth pad for children's gastroscopy

technical field

The invention belongs to the field of medical equipment, and in particular relates to a gastroscope mouth pad for children's gastroscopy.

Background technique

Gastroscopy is the most commonly used inspection method for diagnosing upper gastrointestinal diseases. To facilitate inspection and protect the gastroscope tube, a disposable gastroscope mouth pad (also known as a mouthpiece) is currently used during gastroscopy to keep the subject's mouth open for a long time.

At present, in practice, the saliva in the patient's mouth or the refluxed gastric juice may easily cause nausea, coughing, or flow out of the mouth to contaminate the operating bed, which may lead to interruption of the operation and delay the patient's diagnosis and treatment. Among the methods adopted in the prior art, some are to set absorbent cotton at the mouthpiece of the mouth pad of the gastroscope to absorb saliva, and some are to suck away saliva or gastric juice by setting a suction tube. Among the above two methods, the former can only absorb a certain amount of liquid due to its limited adsorption capacity, while the latter, because the suction position is relatively fixed, when the patient is in different positions, the area where the saliva or gastric juice is concentrated is not the same, resulting in its inconsistency. The saliva or gastric juice in the corresponding position cannot be accurately sucked away, and the suction effect is poor.
