[ background of the invention ]
After a trachea cannula is inserted into a cardiopulmonary resuscitation patient and a critically ill patient with respiratory dysfunction, the cuff of the trachea cannula needs to be inflated, and a gap between the trachea cannula and the trachea of the patient is filled and sealed by the inflated cuff. Clinical experience shows that the cuff pressure of the tracheal catheter is 20-30cm water column which is a proper pressure, if the cuff pressure is less than 20-30cm water column, air leakage and poor intubation effect can be caused, and if the cuff pressure is more than 20-30cm water column, local tissues on the inner wall of the trachea of a patient can be subjected to pressure necrosis, even arterial hemorrhage, and finally airway stenosis of the patient can be caused. Therefore, when using endotracheal tubes, pressure control of the endotracheal tube cuff is particularly important.
At present, medical personnel is when using trachea cannula, generally, the atmospheric pressure of adopting gasbag manometer to cuff repeatedly at the inflation in-process monitors, if the gasbag manometer shows that cuff pressure is low then continue to inflate, if the gasbag manometer shows that cuff pressure is too high then the gassing, whole process operation is troublesome, consume time, and the gasbag manometer is expensive, in the area that medical conditions is than poor, when the patient is numerous, can't satisfy all trachea cannula processes and all can use the gasbag manometer to monitor cuff pressure, furthermore, when the patient needs urgent intubate to salvage, medical personnel do not have the time repetition to monitor cuff pressure, generally need medical personnel to judge according to own experience, the degree of accuracy is lower.
There are also many studies related to monitoring/controlling the pressure of an endotracheal tube cuff in response to the above, but all suffer from different problems. For example, chinese patent CN207640771U discloses a pressure regulator for an endotracheal intubation balloon, which is provided with a side tube, wherein a piston is disposed in the side tube, and an exhaust hole is disposed on a side wall of the side tube, and when the air pressure is greater than a preset air pressure value, the piston moves towards the end of the side tube to communicate a main tube with the exhaust hole for exhausting air, thereby achieving the effect of controlling the pressure, but the scheme has the problem that the pressure cannot be accurately controlled, and is not convenient for medical staff to control the specific air pressure value of the cuff according to the actual condition of a patient; moreover, many studies have been made to improve the existing endotracheal tube structure, which results in waste of the produced endotracheal tube, such as CN207970323U, which discloses monitoring the pressure of the cuff by connecting a bypass to the inflation tube, the bypass being connected to a pressure gauge.
