Description

Tracheal cannula with pressure indicating device Technical Field The utility model belongs to the technical field of medical appliances, and particularly relates to an endotracheal tube with a pressure indicating device. Background The tracheal tube (Endotracheal Tube/Tracheal Tube) is a medical device, which is a special tracheal tube inserted into the trachea through the glottis. When the tracheal cannula is used, in order to avoid secretion of the oral cavity and the nasal cavity flowing into the trachea, the pressure of an air bag or a balloon on the tracheal cannula is required to be ensured to be within a preset range, the lung infection is easily caused by the incorrect inhalation due to the fact that the pressure is too low, and the damage of the tracheal mucosa is easily caused due to the fact that the pressure is too high. Most of the existing air-inserted air passage is provided with a balloon, the balloon is required to be inflated after the intubation, certain requirements are met on the air pressure inside the balloon, medical staff usually need to detect or monitor the air pressure inside the balloon by means of other appliances, if the air pressure of the balloon is not in a standard range, the air pressure of the balloon is possibly harmful to a patient, the air pressure inside the balloon needs to be checked by means of external equipment, time and labor are wasted, and the use cost of equipment is increased.
