Technical Field

[0001] The present invention relates to the technical field of medical tools, and particularly to a visual airbag pressure automatic adjustment device. Background Technique

[0002] An airbag in the medical field is a medical tool used for patients with endotracheal intubation or tracheotomy to fix the trachea, prevent air leakage, and block oral and gastric secretions from entering the lungs. During clinical use, airbag pressure management is crucial. The ideal airbag pressure should be maintained within the range of 25~30 cmH2O, which can effectively seal the gap between the airbag and the trachea and prevent compressive damage of the airbag to the mucosa.

[0029] The gas pre-storage cavity 6 is arranged inside the inner cavity of the airbag body 3. The outer surface of the air charging pipe 4 penetrates through the catheter 1, the gas pre-storage cavity 6 and the first electromagnet 19, and the end of the air charging pipe 4 is arranged inside the inner cavity of the gas pre-storage cavity 6.

[0030] The end of the air outlet pipe 5 penetrates through the conduit 1 and extends into the inner cavity of the airbag body 3. One end of the air charging pipe 4 far from the gas pre-storage cavity 6 penetrates through the conduit 1 and extends to the outside. One end of the air outlet pipe 5 far from the airbag body 3 penetrates through the conduit 1 and extends to the outside.

[0031] The outer surface of the ventilation pipe 7 penetrates through the first electromagnet 19 and the gas pre-storage cavity 6 and extends into the inner cavity of the airbag body 3. The first electromagnet 19 is arranged at the side of the inner surface of the gas pre-storage cavity 6.

[0032] One end of the air charging pipe 4 far from the gas pre-storage cavity 6 is provided with a connector 15. The air charging pipe 4 is connected to the connecting pipe 14 through the connector 15.

[0033] The inner surface of the annular magnetic plate 21 is adapted to the outer surface of the conduit 1, and the outer surface of the annular magnetic plate 21 is adapted to the inner surface of the gas pre-storage cavity 6. The annular magnetic plate 21 is arranged opposite to the first electromagnet 19.

[0034] The outer surface of the fixing plate 801 is fixedly connected to the inner surfaces of the ventilation pipe 7 and the air outlet pipe 5. The bottom end of the first rotating rod 802 is rotatably connected to the inner surfaces of the ventilation pipe 7 and the air outlet pipe 5. The lower surface of the fixing seat 803 is fixedly connected with a support rod 804. The bottom end of the support rod 804 is fixedly connected to the inner surfaces of the ventilation pipe 7 and the air outlet pipe 5.

[0035] The guiding groove 807 is arranged at the end of the second electromagnet 806. The bottom of the ball 809 is in contact with the bottom of the inner surface of the guiding groove 807. The rack 810 is arranged on the upper surface of the fixing seat 803. One end of the second return spring 812 far from the magnetic slider 808 is fixedly connected to the inner surface of the internal slot 811.

[0036] The outer surface of the cylindrical gear 813 is meshed with the outer surface of the rack 810. The outer surface of the first bevel gear 814 is meshed with the outer surface of the second bevel gear 816. The outer surface of the adjusting baffle 817 is attached to the outer surface of the fixing plate 801.

[0037] During use, after the catheter 1 is inserted into the trachea, inflation of the airbag body 3 is started. The deflation device 8 in the ventilation tube 7 is controlled to open by the visualization terminal 2, and the deflation device 8 in the air outlet tube 5 is controlled to close. The inflation pump 13 is started by the visualization terminal 2 and the solenoid valve 16 is opened. Gas enters the gas pre-storage cavity 6 through the inflation tube 4, and then enters the airbag body 3 through the ventilation tube 7, causing the airbag body 3 to inflate. When the second pressure sensor 18 detects that the air pressure value in the airbag body 3 reaches the appropriate range, the deflation device 8 in the ventilation tube 7 is closed, and the inflation pump 13 continues to inject an appropriate amount of gas into the gas pre-storage cavity 6. When the first pressure sensor 17 detects that the air pressure in the gas pre-storage cavity 6 is greater than the air pressure in the airbag body 3, the inflation pump 13 and the solenoid valve 16 are closed, ending the inflation operation. When dynamic adjustment of the air pressure in the airbag body 3 is required, when deflation is needed, the deflation device 8 in the ventilation tube 7 is kept closed through the visualization terminal 2, and the deflation device 8 in the air outlet tube 5 is in the open state, so that the gas in the airbag body 3 is discharged from the air outlet tube 5. When inflation is needed, the deflation device 8 in the air outlet tube 5 is kept closed through the visualization terminal 2, the deflation device 8 in the ventilation tube 7 is in the open state, and the first electromagnet 19 is controlled to be energized to generate a magnetic force through the visualization terminal 2. The first electromagnet 19 generates a suction force on the annular magnetic plate 21. The current intensity is precisely adjusted to control the magnetic force of the first electromagnet 19, so that the annular magnetic plate 21 gradually approaches the first electromagnet 19, and the first return spring 20 is stretched accordingly. The gas in the gas pre-storage cavity 6 is squeezed into the airbag body 3 through the ventilation tube 7. When the second pressure sensor 18 detects that the appropriate air pressure is reached in the airbag body 3, a signal is transmitted to the visualization terminal 2. The first electromagnet 19 is de-energized and the deflation device 8 in the ventilation tube 7 is closed through the visualization terminal 2. After the first electromagnet 19 is de-energized, it loses its magnetic force, and the annular magnetic plate 21 returns to its initial position under the elastic force of the first return spring 20.

[0038] Through the air release device 8, the air release device 8 is in a closed state in its initial state, that is, the adjusting baffle 817 completely blocks the ventilation hole 805. When it is necessary to open the air release device 8, the second electromagnet 806 is controlled to be energized to generate magnetic force through the visualization terminal 2. The second electromagnet 806 generates a suction force on the magnetic slider 808. The current intensity is precisely adjusted to control the magnetic force of the second electromagnet 806, so that the magnetic slider 808 gradually approaches the second electromagnet 806. The second return spring 812 is stretched accordingly. The rack 810 moves with the movement of the magnetic slider 808, driving the cylindrical gear 813 and the first rotating rod 802 to rotate. The first bevel gear 814 rotates accordingly. The first bevel gear 814 drives the second bevel gear 816 and the second rotating rod 815 to rotate. The adjusting baffle 817 rotates accordingly. By controlling the magnetic force of the second electromagnet 806, the opening degree of the ventilation hole 805 can be controlled, so that the rate of gas passing through the air release device 8 can be flexibly adjusted, thereby adjusting the ventilation volume at the air release device 8 to adjust the air pressure in the airbag body 3. When the visualization terminal 2 controls the second electromagnet 806 to be powered off, the second electromagnet 806 loses its magnetic force. The magnetic slider 808 returns to its original position under the elastic pull of the second return spring 812, driving the adjusting baffle 817 back to its original position to completely block the ventilation hole 805, and the air release device 8 is closed. By providing a ball 809 at the bottom of the magnetic slider 808, the ball 809 rolls accordingly during the movement of the magnetic slider 808, which can reduce the resistance during the movement of the magnetic slider 808.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
