[0027] The oral support assembly 10 includes a movable ring 1001, a connecting rod 1002, a limiting plate 1003, a fixed frame 1004, a movable block 1005 and an oral support plate 1006. The movable ring 1001 is arranged on the threaded adjustment tube 903 and is threadedly connected to the threaded adjustment tube 903. The fixed frame 1004 is symmetrically fixed on the threaded adjustment tube 903. The movable block 1005 is slidably arranged in the fixed frame 1004. The connecting rod 1002 is arranged between the movable block 1005 and the movable ring 1001. The connecting rod 1002 is rotatably connected to the movable block 1005 and the movable ring 1001. The limiting plate 1003 passes through the movable ring 1001 and is fixedly connected to the fixed frame 1004. The oral support plate 1006 is fixedly arranged on the movable block 1005.

[0028] When using it specifically, first determine whether the adjustable anti-bite tube mechanism 4 needs to be used according to the patient's condition. If it is not needed, directly unplug the adjustable anti-bite tube mechanism 4 from the snap ring 809. When the snap column 901 is removed from the snap ring 809, the adjustable anti-bite tube mechanism 4 can be removed, and then the suction tube can be connected to the threaded connecting tube 808 for use; if it needs to be used, directly connect the suction tube to the threaded interface 904 for use.

[0029] When the adjustable anti-bite tube mechanism 4 is assembled and used, the sputum suction tube is first inserted into the patient's throat, and then the oral support plate 1006 is inserted into the patient's oral cavity. The distance between the two oral support plates 1006 is adjusted according to the size of the patient's oral cavity. Only the rotating ring 902 is rotated, and the rotating ring 902 drives the threaded adjustment tube 903 and the clamping ring 809 to rotate. Under the limit of the limit plate 1003, the threaded adjustment tube 903 drives the moving ring 1001 to move forward, and the moving ring 1001 drives the connecting rod 1002 to rotate, so that the distance between the two connecting rods 1002 is increased. , the two connecting rods 1002 drive the two moving blocks 1005 to move toward both ends, and the two moving blocks 1005 drive the two oral support plates 1006 to move toward both ends, so that the patient's upper and lower gums are stuck in the oral support plates 1006, thereby achieving oral support for the patient, effectively preventing the transparent hose 710 from causing discomfort to the patient, and the patient closing the mouth and biting the hose due to stress, causing the problem of abnormal sputum suction; then the patient can be suctioned, and the motor 503 only needs to be started, and the motor 503 drives the convex column 504 to rotate, and the convex column 504 drives the rectangular frame 505 to rotate, The rectangular frame 505 drives the screw rod 509, the sliding block 510 and the sliding column 511 to rotate together. The sliding column 511 drives the moving frame 608, the cylinder 609 and the rectangular plate 607 to reciprocate left and right. The rectangular plate 607 drives the piston 606 to reciprocate left and right in the cylindrical tube 601. When the piston 606 moves to the right, the opening and closing plate 702 is forced to open, and the air inside the device is sucked into the cylindrical tube 601. The convex block 605 remains stationary under the limiting action between the limiting block 604 and the U-shaped block 603. When the piston 606 moves to the left, the opening and closing plate 702 closes. The air inside the cylindrical tube 601 is squeezed into the rectangular tube 602, and the air pushes the convex block 605 and the limit block 604 to move upward together. After the convex block 605 moves upward for a certain distance, the inside of the rectangular tube 602 is connected to the outside, and the inside is transported to the outside, and this cycle repeats, so that negative pressure is continuously generated inside the device, and the sputum in the patient's throat is sucked into the threaded adjustment tube 903 from the suction tube, and then passes through the threaded adjustment tube 903, the long hose 807, the rectangular block 701 and the transparent hose 710, so that the sputum enters the storage tube 705, thereby realizing the absorption of the sputum.

[0030] If you need to increase the suction force of the device, you only need to rotate the rotating rod 506. The rotating rod 506 drives the bevel gear 1 507 to rotate, and the bevel gear 1 507 drives the bevel gear 2 508 to rotate. The bevel gear 2 508 drives the screw rod 509 to rotate, and the screw rod 509 drives the sliding block 510 and the sliding column 511 to move to the left together, thereby increasing the distance between the sliding column 511 and the center of the convex column 504. This can increase the stroke of the moving frame 608 when the sliding column 511 rotates and drives the moving frame 608 to move back and forth left and right, thereby increasing the suction force of the device. Similarly, if you want to reduce the suction force of the device, you only need to rotate the rotating rod 506 in the opposite direction.

[0031] When sputum sampling is required, it is only necessary to press the conducting plate 802. The conducting plate 802 moves inward along the fixing box 801 and squeezes the spring 804. The spring 804 contracts under the force. When the round hole on the conducting plate 802 is aligned with the round hole on the fixing box 801, the sucked sputum can be passed from the storage cylinder 705 through the fixing box 801 and the conducting plate 802 into the disposable sputum collector 806. Finally, the disposable sputum collector 806 can be unscrewed from the connecting tube 805.

[0032] When the storage cylinder 705 needs to be cleaned, first unscrew the cover on the liquid inlet pipe 706, add cleaning and disinfecting liquid into the storage cylinder 705 through the liquid inlet pipe 706, then put the cover back in place, and then start the cleaning motor 708. The cleaning motor 708 drives the scraper 707 to rotate, and the scraper 707 automatically cleans the inner wall of the storage cylinder 705. After cleaning is completed, first pull the storage cylinder 705 upward to separate the locking tube 711 from the fixed column 11, so that the storage cylinder 705 can be separated from the liftable movable base 1, and then pull the liquid outlet plate 709 out of the storage cylinder 705, so that the cleaning waste water inside the storage cylinder 705 can flow out from the reserved wastewater hole at the bottom of the storage cylinder 705. After cleaning is completed, the liquid outlet plate 709 and the storage cylinder 705 can be returned to their positions.
