Description

Technical Field

[0002] Oral intubation, usually refers to oral intubation, is an instrument for endotracheal intubation. The oral tube is inserted into the patient's trachea through the mouth. This is a technique for endotracheal anesthesia and rescue of patients. It is also the most reliable means to keep the upper airway open. The main purpose of oral intubation is to maintain airway patency and ensure adequate ventilation and oxygen supply. Oxygen is delivered directly to the lungs through the oral tube to ensure that the patient can breathe normally.

[0003] The catheter used for endotracheal intubation will close the airway through the balloon. The normal pressure of the balloon is generally 20-30cmH2O. The normal pressure level can ensure a certain pressure and tension, and can be tightly combined with the airway to prevent air leakage. However, the current method of measuring balloon pressure is generally manual multiple measurements. It is difficult to detect whether the balloon pressure is at the normal value in time, and the labor cost is high. Therefore, an oral intubation that can display the balloon pressure is needed to solve the above problems. Utility Model Content
