Technical Field

[0001] This application relates to the field of medical device technology, specifically to a disposable gastroscopy bite block. Background Technology

[0002] A gastroscopy (also known as an endoscope) is a medical instrument used to examine the upper part of the digestive tract, including the esophagus, stomach, and duodenum. It is a flexible, tubular instrument, usually inserted through the mouth, and equipped with a camera and light source, allowing doctors to directly observe the inner lining of the digestive tract. During a gastroscopy, the patient needs to keep their mouth open because the endoscope is inserted through the mouth. To reduce discomfort and potential injury to the mouth and teeth during insertion, a bite block (also called a mouthguard) is usually used.

[0003] The current gastroscopy bite block is designed to help patients keep their mouths open so that the endoscope can be inserted smoothly for examination. When the patient bites down on the bite block, the bite force of the lower and upper teeth fixes the bite block in the mouth, thus keeping the patient's mouth in a certain open position. During this process, the soft tissues on both sides of the patient's mouth (such as the cheeks and tongue) will be pulled to a certain extent, causing them to move closer to the center of the mouth. The endoscope is prone to friction with these soft tissues during insertion, which increases the patient's discomfort.

[0004] Therefore, it is necessary to provide disposable endoscope bite blocks to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
