Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a thoracic drainage tube adapter. Background Art

[0002] A drainage tube is used for clinical surgical drainage, which is a medical device that guides pus, blood, and fluid accumulated in human tissues or body cavities to the outside of the body to prevent postoperative infection and promote wound healing. When a thoracic drainage tube is in use, an adapter is required to connect the drainage tube to a drainage bag, so as to drain the body fluid of the patient into the drainage bag. However, the connection part between the existing drainage tube and the adapter is prone to falling off, resulting in the inability of the fluid in the drainage tube to flow into the drainage bag for collection. Summary of the Invention

[0014] The present invention has achieved the following technical effects compared with the prior art: By inserting the drainage tube into the first channel inside the first connector, then pushing the sleeve so that the sleeve gradually moves away from the hand-held portion until the sleeve moves to a suitable position, and finally fixing the sleeve by using the fixing mechanism. During this process, the sleeve drives the piston rod to move inside the second cavity, and the piston rod drives the piston to move away from the hand-held portion. Thus, the air in the first cavity can be sucked into the second cavity through the third through hole, and the air in the second cavity is discharged through the second through hole, so that a negative pressure is formed inside the first cavity. Thereby, the drainage tube can be adsorbed inside the first connector through the first through hole, and further improve the connection stability between the drainage tube and the adapter, and reduce the risk of the drainage tube falling off.

When in use, first insert the drainage tube into the first channel inside the first connector 2, then push the sleeve 9 to make the sleeve 9 gradually move away from the hand-held part until the sleeve 9 moves to a suitable position, and finally fix the sleeve 9 by using the fixing mechanism. During this process, the sleeve 9 drives the piston rod 8 to move inside the second cavity 4, and the piston rod 8 drives the piston 7 to move away from the hand-held part 1, so that the air in the first cavity 3 can be inhaled into the second cavity 4 through the third through-hole 5, and the air in the second cavity 4 is discharged through the second through-hole 10, so as to form a negative pressure inside the first cavity 3, thereby adsorbing the drainage tube inside the first connector 2 through the first through-hole 6, and further improving the connection stability between the drainage tube and the adapter and reducing the risk of the drainage tube falling off.

[0025] In this embodiment, the fixing mechanism includes a first magnet 11 and a second magnet 12; four limiting blocks 13 are provided on the outer side wall of one end of the first connector 2 away from the handheld part 1; the four limiting blocks 13 are distributed in an annular array; a limiting groove 14 adapted to the limiting block 13 is formed on the sleeve 9; the number of the limiting blocks 13 is the same as that of the limiting grooves 14, and they are arranged in one-to-one correspondence; the limiting block 13 is inserted into the corresponding limiting groove 14; a first magnet 11 is provided on one side of the limiting block 13 close to the handheld part 1; a second magnet 12 is provided on one side of the limiting groove 14 close to the handheld part 1; when in use, first insert the drainage tube into the first channel inside the first connector 2, and then push the sleeve 9 to move the sleeve 9 away from the handheld part until the sleeve 9 moves to a proper position so that the first magnet 11 and the second magnet 12 are adsorbed together, thus realizing the fixation of the sleeve 9. When it is necessary to remove the drainage tube, push the sleeve 9 in the direction of the handheld part 1 to a proper position, and then pull out the drainage tube.

On the one hand, it is convenient for the storage of the adapter, and on the other hand, it avoids the sleeve from shaking when taking or inserting the drainage tube, which affects the working efficiency.

[0034] In this embodiment, the inner diameter of the connecting ring 15 is smaller than the inner diameter of the first channel inside the first connector 2.

[0035] In some other embodiments, the numbers of the first cavity 3 and the second cavity 4 can be designed according to actual situations.

[0036] In some other embodiments, the numbers of the limiting block 13 and the limiting groove 14 can be designed according to actual situations.
