Problems solved by technology

[0002] The currently used tracheal tubes generally have no cuff pressure display device, and only rely on the doctor's experience to judge the amount of inflation; with the improvement of technology, pressure display devices that can display cuff pressure, such as pressure display balls and pressure sensors, have appeared one after another. , the pressure display ball and the cuff are communicated through the one-way air valve. When inflated, the cuff and the pressure display ball expand together. The air intake of the cuff is controlled according to the expansion of the pressure display ball, but when the pressure display ball is inflated, the volume changes. Large, there are problems of inconvenient operation and easy misuse to damage the pressure display ball; while the pressure sensor is expensive and not suitable for use in the configuration of a disposable endotracheal tube

Abstract

The invention discloses a low-pressure-controllable endotracheal tube comprising an endotracheal tube body (1). The low-pressure-controllable endotracheal tube is characterized in that the front end of the endotracheal tube body (1) is provided with a cuff (2) connected to an inflating bin (4) through a cuff tube (3), the gas inlet of the inflating bin (4) is provided with a gas needle (5) which is located at the center of the circle and which is used for inflating and sealing and a low pressure display device (6) which is located at the circumference of the center of the circle and which wraps the gas needle (5), and the gas inlet of the inflating bin (4) is provided with scales. The low-pressure-controllable endotracheal tube is simple in design, low in cost and convenient to use, and security and controllability can be achieved due to pressure display.
