A ventilation tube 8 is connected to the middle of the connecting tube 6. A plug 9 is fitted into one end of the ventilation tube 8.

[0021] The fixing mechanism 4 includes a first fixing block 401, a second fixing block 402, a sealing groove 403, a connecting block 404, a limiting groove 405, a locking block 406, a movable groove 407, a limiting block 408, a connecting rod 409, a spring 410, a pull ring 411, a sealing ring 412, and a locking groove 413. The first fixing block 401 is fixedly connected to one side of the surface of the collection bottle 1, and the second fixing block 402 is fixedly connected to one side of the surface of the collection bottle 1. A sealing groove 403 is provided on the top of the collection bottle 1. A connecting block 404 is fixedly connected to one side of the surface of the bottle cap 2, and a limiting groove 405 is provided on one side of the surface of the bottle cap 2. A locking block 405 is fixedly connected to one side of the surface of the first fixing block 401. 06. The second fixing block 402 has an internal movable groove 407. A limiting block 408 is fitted inside the movable groove 407. A connecting rod 409 is fixedly connected to one end of the limiting block 408. A spring 410 is sleeved on the surface of the connecting rod 409. A pull ring 411 is fixedly connected to one end of the connecting rod 409. A sealing ring 412 is fitted inside the sealing groove 403. A slot 413 is opened on one side of the surface of the connecting block 404. The mechanism is connected by an mounting block 301, a connecting buckle 302, a gathering strap 303, a first adhesive sheet 304, a second adhesive sheet 305, a fixing mechanism 4, a first fixing block 401, a second fixing block 402, a sealing groove 403, a connecting block 404, and a limiting ring 411. The arrangement of the slot 405, locking block 406, movable slot 407, limiting block 408, connecting rod 409, spring 410, pull ring 411, sealing ring 412, and locking groove 413 is as follows: During use, when the bottle cap 2 needs to be installed on top of the collection bottle 1, pulling the pull ring 411 causes the limiting block 408 to move into the movable slot 407 via the connecting rod 409. Simultaneously, the limiting block 408 compresses the spring 410, causing it to deform. When the limiting block 408 is fully engaged in the movable slot 407, the bottle cap 2 is pressed onto the top of the collection bottle 1. Then, rotating the bottle cap 2 causes the locking block 406 to fully engage in the locking groove 413. At this point, the movable groove 407 and the limiting groove 405 are aligned. When the force applied to the pull ring 411 is released, the spring 410 rebounds and causes the limiting block 408 to return to its original position. At this time, one end of the limiting block 408 is fitted inside the movable groove 407, and the other end is fitted inside the limiting groove 405. Thus, the locking block 406 and the limiting block 408 fix the bottle cap 2. The sealing ring 412 makes the bottle cap 2 and the collection bottle 1 form a sealed connection. When it is necessary to remove the bottle cap 2, simply pull the pull ring 411 to make the limiting block 408 fully fitted inside the movable groove 407. Then rotate the bottle cap 2 to make the locking block 406 disengage from the locking groove 413 to remove the bottle cap 2.

[0022] Furthermore, the first fixing block 401 and the second fixing block 402 are symmetrically distributed, the connecting block 404 is aligned with the first fixing block 401, and the limiting groove 405 is aligned with the second fixing block 402. With the setting of the limiting groove 405, when in use, one end of the limiting block 408 is fitted into the inside of the limiting groove 405 to limit and fix the bottle cap 2.

[0023] Furthermore, one end of the locking block 406 is fitted inside the locking groove 413, and one end of the limiting block 408 is fitted inside the limiting groove 405. With the setting of the locking block 406, when in use, the locking block 406 can be fitted inside the locking groove 413 to initially fix the bottle cap 2, and at the same time, the limiting groove 405 and the movable groove 407 can be aligned.

[0024] Furthermore, one end of the spring 410 is fixedly connected to the second fixing block 402, and the other end of the spring 410 is fixedly connected to the limiting block 408. With the setting of the spring 410, when in use, the spring 410 rebounds and deforms, which can drive the limiting block 408 to return to its original position.

[0025] Furthermore, the gathering mechanism 3 includes a mounting block 301, a connecting buckle 302, a gathering strap 303, a first adhesive sheet 304, and a second adhesive sheet 305. The mounting block 301 is fixedly connected to one side of the surface of the collection bottle 1, the connecting buckle 302 is fixedly connected to one side of the surface of the collection bottle 1, the gathering strap 303 is sewn to one side of the surface of the mounting block 301, the first adhesive sheet 304 is sewn to one side of the surface of the gathering strap 303, and the second adhesive sheet 305 is sewn to one side of the surface of the gathering strap 303. The gathering mechanism 3 is connected via the mounting block 301, the connecting buckle 302, the gathering strap 303, the first adhesive sheet 304, and the second adhesive sheet 305. With the installation of the tab 305, after the suctioning operation is completed and the bottle is cleaned, the suction tube 5, connecting tube 6, and syringe 7 are attached to the surface of the collection bottle 1. Then, the drawstring 303 is pulled so that one end of the drawstring 303 wraps around the collection bottle 1 and passes through the inside of the connecting buckle 302. Then, the drawstring 303 is pulled back so that the first adhesive tab 304 and the second adhesive tab 305 are attached together. Since the first adhesive tab 304 is the hook and loop side of the Velcro and the second adhesive tab 305 is the fleece side of the Velcro, the first adhesive tab 304 and the second adhesive tab 305 are bonded together, which can manage the suction tube 5, connecting tube 6, and syringe 7.

[0026] Furthermore, the drawstring 303 is an elastic band, with one end of the drawstring 303 penetrating the interior of the connecting buckle 302. Due to the elasticity of the drawstring 303, it can be pulled as needed during use, so that the suction tube 5, the connecting tube 6, and the syringe 7 fit tightly against the surface of the collection bottle 1.

[0027] Furthermore, the first adhesive piece 304 and the second adhesive piece 305 are both sewn together on the same side of the surface of the drawstring 303. The first adhesive piece 304 is the hook and loop side of the hook and loop fastener, and the second adhesive piece 305 is the fleece side of the hook and loop fastener. With the arrangement of the first adhesive piece 304 and the second adhesive piece 305, when the first adhesive piece 304 and the second adhesive piece 305 are attached to each other during use, they can be bonded together to fix the drawstring 303.

[0028] Working principle: In use, when it is necessary to install the bottle cap 2 on top of the collection bottle 1, pull the pull ring 411. The pull ring 411 drives the limiting block 408 to move into the movable groove 407 through the connecting rod 409. At the same time, the limiting block 408 compresses the spring 410, causing the spring 410 to deform. When the limiting block 408 is fully engaged in the movable groove 407, the bottle cap 2 is pressed onto the top of the collection bottle 1. Then, rotate the bottle cap 2 to make the locking block 406 fully engage. Inside groove 413, the movable groove 407 and the limiting groove 405 are aligned. Releasing the force applied to the pull ring 411 causes the spring 410 to rebound, returning the limiting block 408 to its original position. At this point, one end of the limiting block 408 is engaged inside the movable groove 407, and the other end is engaged inside the limiting groove 405. Thus, the locking block 406 and the limiting block 408 fix the bottle cap 2, and the sealing ring 412 forms a sealed connection between the bottle cap 2 and the collection bottle 1. When needed... To remove bottle cap 2, simply pull the pull ring 411 to fully engage the limiting block 408 inside the movable groove 407. Then, rotate bottle cap 2 to disengage the locking block 406 from the groove 413, thus removing bottle cap 2. Pull the syringe 7; at this time, the syringe 7, through the connecting tube 6, creates a negative pressure inside the collection bottle 1. The suction tube 5 can then collect sputum from the patient. After the suctioning operation is completed and the bottle is cleaned, attach the suction tube 5, connecting tube 6, and syringe 7 to the collection bottle. On the surface of 1, the drawstring 303 is then pulled so that one end of the drawstring 303 wraps around the collection bottle 1 and passes through the inside of the connecting buckle 302. Then the drawstring 303 is pulled back so that the first adhesive piece 304 and the second adhesive piece 305 are attached together. Since the first adhesive piece 304 is the hook and loop side of the Velcro and the second adhesive piece 305 is the fleece side of the Velcro, the first adhesive piece 304 and the second adhesive piece 305 are bonded together, which can be used to manage the suction tube 5, the connecting tube 6 and the syringe 7.
