[0022] Example 1: as Figures 1-4The utility model provides a kind of anesthesia machine circuit adapter for bronchoscopy, it include: adapter 1, first pivot shaft 2 is rotatably connected in the inner wall of adapter 1, second pivot shaft 3 is movably sheathed on the outer surface of first pivot shaft 2 and near top portion, first baffle 4 is fixedly connected on the outer surface of first pivot shaft 2, second baffle 5 is fixedly connected on the outer surface of second pivot shaft 3, first gear 6 is fixedly connected on the outer surface of second pivot shaft 3 and near top end, first connecting plate 7 is rotatably connected on the outer surface of first gear 6 and near bottom end, second connecting plate 8 is fixedly connected on the top of first connecting plate 7 and near one side edge, second gear 9 is rotatably connected on the outer surface of second connecting plate 8 and near center, third connecting plate 10 is fixedly connected on the top of second connecting plate 8, third gear 11 is fixedly sheathed on the outer surface of first pivot shaft 2 and near one end, two second limit plates 19 are fixedly connected on the inner wall of adapter 1, one end of first pivot shaft 2 movably penetrates adapter 1 and extends to outside, the outer surface of second baffle 5 is contacted with the outer surface of first pivot shaft 2, the outer surface of second baffle 5 is contacted with the outer surface of first pivot shaft 2, the inner wall of third connecting plate 10 is contacted with the outer surface of third gear 11, the outer surface of third gear 11 is engaged with the outer surface of second gear 9, the outer surface of first gear 6 is engaged with the outer surface of second gear 9.
[0023] The effect achieved by the whole embodiment 1 is that when the adapter of the anesthesia machine circuit for bronchoscopy is used, the medical staff first needs to connect one end of the adapter 1 with the anesthesia machine and the other end with the bronchoscope. In operation, the anesthesia gas generated by the anesthesia machine enters the adapter 1. When the anesthesia gas flows in the adapter 1, it drives the first baffle 4 and the second baffle 5 to move towards each other. When the first baffle 4 is displaced and rotated, it drives the first shaft 2 to rotate. When the first shaft 2 rotates, it drives the third gear 11 to rotate. When the third gear 11 rotates, it drives the second gear 9 to rotate. When the second gear 9 rotates, it drives the first gear 6 to rotate. When the first gear 6 rotates, it drives the second shaft 3 to rotate. When the second shaft 3 rotates, it drives the second baffle 5 to rotate. At the same time, when the second baffle 5 is displaced and rotated, it drives the second shaft 3 to rotate. When the second shaft 3 rotates, it drives the first gear 6 to rotate. When the first gear 6 rotates, it drives the second gear 9 to rotate. When the second gear 9 rotates, it drives the third gear 11 to rotate. When the third gear 11 rotates, it drives the first shaft 2 to rotate. When the first shaft 2 rotates, it drives the first baffle 4 to rotate. The anesthesia gas flows into the bronchoscope through the gap between the first baffle 4 and the adapter 1 and the gap between the second baffle 5 and the adapter 1. When the concentration of the anesthetic and the tracheal pressure of the patient do not match, it will cause the anesthetic to backflow. When the anesthetic backflows, the backflow gas will flow in the adapter 1, which drives the first baffle 4 and the second baffle 5 to move away from each other. When the backflow gas passes through the first baffle 4, it drives the first baffle 4 to be displaced and rotated. The first baffle 4 drives the first shaft 2 to rotate. When the first shaft 2 rotates, it drives the third gear 11 to rotate. When the third gear 11 rotates, it drives the second gear 9 to rotate. When the second gear 9 rotates, it drives the first gear 6 to rotate. When the first gear 6 rotates, it drives the second shaft 3 to rotate. When the second shaft 3 rotates, it drives the second baffle 5 to rotate, until the outer surface of the first baffle 4 is in contact with the second limiting plate 19. At the same time, when the second baffle 5 is displaced and rotated, it drives the second shaft 3 to rotate. When the second shaft 3 rotates, it drives the first gear 6 to rotate. When the first gear 6 rotates, it drives the second gear 9 to rotate. When the second gear 9 rotates, it drives the third gear 11 to rotate. When the third gear 11 rotates, it drives the first shaft 2 to rotate. When the first shaft 2 rotates, it drives the first baffle 4 to rotate, until the second baffle 5 is in contact with the second limiting plate 19. At this time, the gas cannot continue to backflow through the blockage between the first baffle 4 and the second baffle 5, which can effectively ensure the anesthesia effect and reduce the risk of surgery.
[0024] Embodiment 2: as Figures 1-4As shown, the inner part of the second gear 9 is fixedly connected with a connecting shaft 12, one end of the connecting shaft 12 is provided with a groove 13, the outer surface of the adapter 1 is fixedly connected with a box body 18, one side of the outer surface of the box body 18 is rotatably connected with a third rotating shaft 16, the outer surface of the third rotating shaft 16 is fixedly connected with a limiting block 17, one end of the third rotating shaft 16 movably penetrates through the box body 18 and extends into the interior, one end of the third rotating shaft 16 is fixedly connected with a first limiting plate 15, the outer surface of the first limiting plate 15 is fixedly connected with a protrusion 14, the outer surface of the first rotating shaft 2 is rotatably connected with the inner wall of the second rotating shaft 3, and the outer surface of the protrusion 14 is slidably connected with the inner wall of the groove 13.
[0025] The effect achieved by the whole embodiment 2 is that when the distance between the first baffle 4 and the second baffle 5 is too small and the anesthetic agent cannot flow smoothly or the distance between the first baffle 4 and the second baffle 5 is too large and the anesthetic agent flows too much, the staff can push the third rotating shaft 16 into the box body 18, the third rotating shaft 16 will drive the limiting block 17 to move, and at the same time, the first limiting plate 15 will also be driven to move, and the first limiting plate 15 will drive the protrusion 14 to move, until the limiting block 17 is attached to the box body 18 and the outer surface of the protrusion 14 is attached to the groove 13, at this time, the third rotating shaft 16 is rotated, the third rotating shaft 16 will drive the protrusion 14 to rotate, the protrusion 14 will drive the connecting shaft 12 to rotate, the connecting shaft 12 rotating will drive the second gear 9 to rotate, the second gear 9 rotating will simultaneously drive the first gear 6 to rotate and the third gear 11 to rotate, the first gear 6 rotating will drive the second rotating shaft 3 to rotate, the second rotating shaft 3 rotating will drive the second baffle 5 to displace, and at the same time, the third gear 11 rotating will drive the first rotating shaft 2 to rotate, the first rotating shaft 2 rotating will drive the first baffle 4 to rotate, thereby changing the distance between the first baffle 4 and the second baffle 5, when it is not necessary for the medical staff to manually adjust, the third rotating shaft 16 can be moved out of the box body 18, the third rotating shaft 16 will drive the limiting block 17 to move, and at the same time, the first limiting plate 15 will also be driven to move, and the first limiting plate 15 will drive the protrusion 14 to move, until the first limiting plate 15 is attached to the box body 18, and the protrusion 14 is located outside the groove 13, thereby improving the flexibility of the adapter 1.
