Specifically, the endotracheal tube body 1 is a medical instrument, which is often used to manage the airway of patients in clinic. It inserts the airway through the oral cavity or nasal cavity to ensure the airway unobstructed and help to maintain effective breathing. It includes a tube body, an inflatable tube and a connector, which 1s a mature technology at present. The outer air bag 2 1s used to seal the airway, its bottom is fixedly connected to the surface of the endotracheal tube body 1, and its top is fixedly connected to the surface of the housing 17 to form a sealed environment, and the inner air bag 3 is in contact with the extrusion plate 11; one side of the pressure gauge 5 is fixedly connected with a detection probe, and the detection end of the detection probe is positioned in the detection air bag 10; the detection probe is fixedly connected with the detection air bag 10 to detect the inner pressure of the detection air bag 10. During use, since both the inner air bag 3 and the detection air bag 10 are inflated and the air pressure is stable, the detection value of the pressure gauge 5 remains unchanged, and the suction cylinder 7 can be disassembled and squeezed to exhaust air, so that the inside of the suction cylinder 7 1s screwed on the connecting tube 22 in a negative pressure state.

At this time, the numerical value detected by the pressure gauge 5 changes and exceeds the initial detection value, and the alarm 16 gives an alarm, so that the first check valve 23 can be opened and the secretion can be sucked out through the suction cylinder 7 with inner negative pressure, thereby ensuring the air pressure of the outer air bag 2 and the sealing effect on the airway.
Embodiment 3
Referring to Figs. 1- 8, on the basis of Embodiment 1 and Embodiment 2, the inflation component further comprises an air inlet tube 24, and the air inlet tube 24 1s communicated with the extrusion balloon 8; a second check valve 25 is sleeved on the surface of the air inlet tube 24, and a third check valve 26 is sleeved at the
Joint of the through tube 9 and the extrusion balloon 8; one side of the through tube
9 1s communicated with an exhaust tube 27, and the surface of the exhaust tube 27099997 1s screwed with a tube cover 28; a supporting rod 29 is fixedly connected below the extrusion plate 11, and the bottom of the supporting rod 29 is fixedly connected with a limiting block; a supporting box 30 is arranged inside the outer air bag 2, and one side of the supporting box 30 is provided with a through groove; the inner air bag 3 1s fixedly connected to the surface of the endotracheal tube body 1; the through tube 9 is communicate with the outer air bag 2, and the housing 17 is fixedly connected to the surface of the endotracheal tube body 1; the housing 17 and the endotracheal tube body 1 are in contact with the piston plate 18.
Specifically, when inflating the outer air bag 2, the second check valve 25 and the third check valve 26 can be intermittently opened, and the extrusion balloon 8 is pressed to inflate; the bottom of the supporting box 30 is provided with a limiting groove adapted to the limiting block, which can limit the extrusion plate 11; the through tube 9, the drainage tube 21 and the endotracheal tube body 1 are all fixedly connected; the supporting box 30 is located on the surface of the inner air bag 3 and is fixedly connected to the surface of the endotracheal tube body 1.
The working principle of the invention is that when the outer air bag 2 inflates, both the inner air bag 3 and the detection air bag 10 are inflated, and the pressure gauge 5 monitors and detects the pressure in the air bag 10 in real time. If the outer air bag 2 is inflated too much, the inner air bag 3 will be squeezed, resulting in an increase in the pressure in the detection air bag 10; after the pressure gauge 5 detects the pressure change, it triggers the alarm 16 to prompt the medical staff to stop inflating or deflate through the exhaust tube 27 and the tube cover 28. On the other hand, if the air bag pressure is insufficient, the system will automatically replenish gas to ensure the tightness between the outer air bag 2 and the airway wall.
When secretions accumulate above the outer air bag 2, the secretions will transfer pressure through the piston plate 18 and the movable rod 14, squeezing the inner air bag 3, resulting in the pressure change in the detection air bag 10. When the pressure gauge 5 detects abnormal pressure, it triggers the alarm 16, and at the same time, the first check valve 23 is opened, and the suction cylinder 7 sucks out the secretion through negative pressure, so as to ensure the pressure stability of the air bag and prevent the secretion from leaking.
The through tube 9 controls the inlet and outlet of gas through the second check valve 25, the third check valve 26 and the exhaust tube 27. The medical staff inflates the gas into the outer air bag 2 by pressing the extrusion balloon 8, and releases the gas through the exhaust tube 27 when it is necessary to exhaust. In the whole process, automatic adjustment is realized through the cooperation of the pressure gauge 5 and the alarm 16, so as to ensure that the pressure of the outer air bag 2 is always within a safe range.
Through the above mechanism, the invention realizes the automatic monitoring and adjustment of the pressure of the outer air bag 2, and can automatically deal with the problem of secretion accumulation at the same time, which significantly improves the safety and use efficiency of the endotracheal tube body 1.

The preferred embodiments do not describe all the details in detail, nor are they limited to the specific embodiments described above. These embodiments are selected and described in detail in this specification in order to better explain the principles and practical applications of the present invention, so that people in the technical field can better understand and utilize the present invention.
