Description

A cuff pressure adjustment measuring device after tracheal intubation

Technical field:

The utility model relates to the field of pressure monitoring of an intubation air bag, in particular to a cuff pressure regulating and measuring device after tracheal intubation.

Background technique:

The existing ventilator inserts an endotracheal tube into the patient's trachea, and there is a high-volume low-pressure cuff at the front end of the endotracheal tube. The cuff is inflated and pressed against the patient's trachea wall by manual injection with a syringe, so as to prevent the gas in the airway from flowing out of the airway. The overflow between the tube and the tracheal wall prevents vomit, blood or oral secretions from flowing into the trachea. The end of the tracheal tube is connected to the Y-shaped interface of the ventilator, so that the ventilator can inject oxygen into the patient through the tracheal tube, so that the patient can control breathing. The normal value is generally 25 to 30cmH2O, the pressure should not be too small, otherwise it will leak, and the pressure should not be too high, otherwise it will cause damage to the airway mucosa.

In the actual use process, the degree of pressurization and inflation of the cuff is not easy to control. At present, most doctors rely on experience to touch and communicate with the air bag to indicate the inflation amount of the balloon when using the endotracheal tube. The size of the airbag inflation at the central position, this method is purely based on experience and feel, and there is no uniform judgment standard. To solve this problem, the hospital connected a pressure gauge to the airbag and injected air into the airbag at the same time. After the pressure stabilized, the pressure gauge was removed. However, in this method, the syringe is manually inflated, the pressure is not easy to fine-tune, and the value of the pressure gauge fluctuates. It takes repeated adjustments by doctors and nurses to reach the above normal value range. It needs to be adjusted as soon as possible and accurately, so as to reduce the risk to the patient. damage.
