[0028] Please refer to 2-4 and Figure 8-10 The suction tube removal mechanism is provided on the negative pressure cylinder 1 for uniformly removing the suction tube 3 and adjusting its position. The suction tube removal mechanism is composed of a mounting cylinder 6, a positioning assembly 7 and a removal assembly 8, as described below: The mounting tube 6 is fixedly mounted on the bottom of the negative pressure tube 1, and a limiting groove is provided on the outer wall of one side of the mounting tube 6; The positioning assembly 7 is provided on the mounting tube 6 and is used for temporary positioning of the connecting mechanism 2.

The removal component 8 is arranged on the mounting tube 6, which is used for uniform movement and position adjustment of the positioning component 7 and the suction tube 3. Specifically: the removal component 8 includes a limit plate 801, a positioning ring 802 and a fixed convex plate 803.

The positioning ring 802 is fixedly sleeved on the outer wall of the mounting tube 6. The fixed convex plate 803 is fixedly connected to the outer wall of the mounting tube 6. A mounting screw 804 is rotatably embedded between the positioning ring 802 and the outer wall of the fixed convex plate 803, and the mounting screw 804 threadedly penetrates the limit plate 801. A first motor 805 is fixedly installed on the outer wall of one side of the fixed convex plate 803, and the output end of the first motor 805 is fixedly connected to one end of the mounting screw 804.

[0029] 702 and 703 are connected to the suction tube 3 by the first motor 805.

[0030] See also Figure 9-10 The positioning assembly 7 also includes a mounting seat 705, which is rotatably connected to the outer wall of one side of the mounting ring 701. A threaded rod 706 is rotatably embedded in the outer wall of one side of the mounting seat 705.

A second motor 708 is fixedly installed on the outer wall of one side of the mounting seat 705, and the output end of the second motor 708 is fixedly connected to one end of the threaded rod 706.

[0031] In this embodiment, the second motor 805 also adopts a motor with a self-locking function. The second motor 708 on the mounting seat 705 can conveniently drive the threaded rod 706 to rotate, and conveniently drive the threaded block 707 to move. Since the mounting seat 705 rotates to connect the mounting ring 701, the threaded block 707 rotates to connect the annular frame 702, and then conveniently drives the annular frame 702 to rotate inside the mounting ring 701, and cooperates with the mounting sleeve 703 to conveniently drive the positioning rod 704 to offset, thereby realizing the positioning of the connecting mechanism 2 and improving the ease of use of the suction tube removal mechanism.

[0032] See also Figure 4-5 A connecting mechanism 2 is provided on the negative pressure cylinder 1 for connecting the negative pressure cylinder 1 and the suction tube 3. Specifically, the connecting mechanism 2 includes a mounting tube 201, a bellows 202 and a hard tube 203. The mounting tube 201 is connected to the bottom of the negative pressure cylinder 1, the bellows 202 is connected to the bottom of the mounting tube 201, and the hard tube 203 is connected between the other end of the bellows 202 and one end of the suction tube 3. Two limiting rings 204 are fixed on the outer wall of the hard tube 203.

[0033] In the embodiment, the mounting tube 201 is threadedly connected to the bottom of the negative pressure cylinder 1, which is convenient for replacing and cleaning the connecting mechanism 2 and the suction tube 3. The length of the connecting mechanism 2 can be conveniently adjusted by the extension and contraction of the bellows 202, and then cooperates with the suction tube removal mechanism. The hard tube 203 corresponds to the positioning component 7 to avoid affecting the use of the suction tube 3 when the positioning component 7 is performing the clamping work. Multiple positioning rods 704 are located between the two limiting plates 204 to improve the use effect of the positioning component 7 and the removal component 8.

[0034] See also Figure 1-2 and Figure 8 , a plurality of limiting rods 9 are fixedly connected between the inner walls of the mounting cylinder 6, and each limiting rod 9 passes through the mounting ring 701; A breathing mask 10 is threadedly embedded in the bottom of the mounting tube 6 .

[0035] In this embodiment, the limiting rod 9 is fixed to the inside of the mounting cylinder 6 and passes through the mounting ring 701, thereby improving the stability of the mounting ring 701 when it is raised and lowered inside the mounting cylinder 6. The breathing mask 10 is connected to the patient's mouth, which facilitates the use of the negative pressure cylinder 1 and the negative pressure suction mechanism and the suction tube removal mechanism.

[0036] Working principle: In the initial state, the positioning rod 704 abuts the outer wall of the hard tube 203, the connecting mechanism 2 is in the positioning state, and the piston 401 is located at the bottom of the negative pressure cylinder 1. When in use, the breathing mask 10 abuts the patient's mouth and extends the bottom end of the suction tube 3 into the root of the patient's tongue. The cylinder 502 and the first motor 805 on the fixing plate 501 are started. The cylinder 502 drives the connecting rod 503 and the push-pull rod 402 to move upward, driving the piston 401 to move, so that the negative pressure cylinder 1 instantly generates negative pressure, and cooperates with the suction tube 3 on the connecting mechanism 2 to suck foreign matter from the patient's airway. At the same time, the first motor 805 drives the mounting screw 804 to rotate, driving the limiting plate 801 to move inside the limiting groove, driving the positioning assembly 7 to move upward, driving the connecting mechanism 2 and the suction tube 3 at the bottom thereof to slowly move out of the patient's mouth, thereby improving the foreign body suction effect. When the first suction is unsuccessful, the cylinder 502 and the first motor 805 are started to restore the piston 401 positioning assembly 7 to its original position. With the cooperation of the first one-way valve 403 and the second one-way valve 404, it is possible to prevent the gas from entering the airway through the suction tube 3 during the piston's descent and pressing the foreign body deeper into the airway. During disassembly and cleaning, start the second motor 708 on the mounting seat 705, and the second motor 708 drives the threaded rod 706 to rotate, driving the threaded block 707 to move. Since the threaded block 707 is rotatably installed on the annular frame 702, the mounting seat 705 is rotatably installed on the mounting ring 701, and then drives the annular frame 702 to rotate inside the mounting ring 701, driving multiple mounting sleeves 703 to move. Since the positioning rod 704 is movably embedded in the corresponding mounting sleeve 703, and one end of each positioning rod 704 is rotatably connected to the outer wall of the mounting ring 701, the other end of the positioning rod 704 is driven to detach from the outer wall of the hard tube 203, unscrew the bolts on the positioning ring 802, remove the mounting tube 6 from the bottom of the negative pressure tube 1, and rotate the mounting tube 201 to remove the connecting mechanism 2 and the suction tube 3.
