Abstract
Description
Technical Field
[0001] The invention relates to the technical field of postoperative drainage for thoracic surgery, in particular to an anti-mispulling self-locking clamp sealing structure for a postoperative drainage tube for thoracic surgery. Background Art
[0002] Postoperative drainage in thoracic surgery is a very important part of clinical treatment. Its main purpose is to discharge fluid, gas or blood in the chest cavity. It can promote lung re-expansion, prevent infection and monitor postoperative recovery. The postoperative drainage tube in thoracic surgery is a medical device for extracting internal body fluids of patients. The drainage tube consists of two parts. The connecting tube is connected to the patient's chest cavity, and the delivery tube is connected to the drainage bottle. During the specific operation, the connecting tube needs to be connected to the patient's chest cavity. The other end of the connecting tube is provided with a clamp with a raised structure. The diameter of the clamp is larger than the inner diameter of the delivery tube. Based on this structural feature, the end of the connecting tube with the clamp can be inserted into the interior of the delivery tube. At this time, the delivery tube relies on its own retractable characteristics, and its inner wall will fit tightly and wrap the position of the clamp, thereby achieving a stable connection between the connecting tube and the delivery tube.
[0003] Although the delivery tube achieves connection with the connecting tube by virtue of its own retractable characteristics, this connection form has obvious shortcomings in terms of stability. Under the interference of external force, the connection is very likely to loosen and separate. Once the two are separated, the body fluid in the patient's chest cavity will lose its restraint and flow uncontrollably to the bed, which will not only pollute the ward environment, but also the bed soaked with body fluids will cause great inconvenience to the patient's normal use. Summary of the Invention

[0008] Specifically, there are four sliding plates in total, and the sliding plates are all slidably connected to the inside of the annular groove. The sliding plates slide through the annular groove and are fixedly connected to the rotating ring. One end of the limiting magnet is set as the south pole, and the other end of the limiting magnet is set as the north pole.

The connecting tube 1 is connected to the delivery tube 2 via the circular tube 6 and the sealing layer 7; When in use, the delivery tube 2 can be held by hand so that one end of the delivery tube 2 is docked with the circular tube 6, and then the delivery tube 2 is pushed forcefully toward the circular tube 6. As the delivery tube 2 is connected to the circular tube 6, the inner diameter of the delivery tube 2 will be squeezed and deformed by the sealing layer 7. At this time, the delivery tube 2 is connected to the connecting tube 1, and the drainage of the fluid accumulated in the patient's body can be carried out normally.

The first clamp self-locking mechanism 4 includes a plurality of sliding plates 41. One end of the sliding plate 41 is fixedly connected to the limiting magnet 42. There are four sliding plates 41 in total. The sliding plates 41 are all slidably connected to the inside of the annular groove 35. The sliding plates 41 slide through the annular groove 35 and are fixedly connected to the rotating ring 32. One end of the limiting magnet 42 is set as the South Pole, and the other end of the limiting magnet 42 is set as the North Pole. A second clamp self-locking mechanism 5 is provided on one side of the conveying pipe 2 to cooperate with the first clamp self-locking mechanism 4 to complete self-locking. The second clamp self-locking mechanism 5 includes a connecting ring 51. A plurality of sliding grooves 52 are opened on the connecting ring 51. A passage groove 53 is provided on the connecting ring 51 at the position corresponding to the sliding groove 52, and a limiting groove 54 is provided inside the connecting ring 51 at the position corresponding to the sliding groove 52. A first magnet 55 is fixedly connected to the limiting groove 54, and a second magnet 56 is fixedly connected to the limiting groove 54. The connecting ring 51 is fixedly connected to one side of the conveying pipe 2. There are four sliding grooves 52, four passage grooves 53, and four limiting grooves 54. The sliding grooves 52, the passage grooves 53 and the limiting grooves 54 are connected to each other. The first magnet 55 and the second magnet 56 are symmetrically fixedly connected to the limiting groove 54. One end of the first magnet 55 is set as a south pole, and one end of the second magnet 56 is set as a south pole.

At this time, the sliding plate 41 and the limiting magnet 42 are pushed toward the conveying pipe 2 through the connecting pipe 1 and the mounting ring 31. The limiting magnet 42 will first be inserted into the passage groove 53, and then the sliding plate 41 will be connected to the inside of the sliding groove 52. At this time, the sliding plate 41 and the limiting magnet 42 are continued to be moved, and the moved limiting magnet 42 will move to the inside of the limiting groove 54. At this time, the south pole position of the first magnet 55 will correspond to the south pole position of the limiting magnet 42, and the south pole position of the second magnet 56 will correspond to the south pole position of the limiting magnet 42. The position of the limiting magnet 42 will correspond to the north pole position of the limiting magnet 42, then a repulsive force will be generated between the first magnet 55 and the limiting magnet 42, and a magnetic attraction will be generated between the second magnet 56 and the limiting magnet 42.

At this time, the connecting pipe 1 and the conveying pipe 2 are self-locked by the cooperation of the first clamp self-locking mechanism 4 and the second clamp self-locking mechanism 5. When operating, it is only necessary to connect the connecting pipe 1 and the conveying pipe 2. After the connection is completed, the first clamp self-locking mechanism 4 and the second clamp self-locking mechanism 5 will self-lock, without manual intervention by the staff. The operation is extremely convenient, and the connection between the connecting pipe 1 and the conveying pipe 2 is tighter, which can prevent the conveying pipe from being stuck. 2 and the connecting tube 1 fall off during use. When the connecting tube 1 and the delivery tube 2 need to be separated, it is only necessary to reset the pushing block 34 to its original position. The pushing block 34 will drive the rotating ring 32 to rotate, and the rotating ring 32 will drive the sliding block 41 and the limiting magnet 42 to reset to between the first magnet 55 and the second magnet 56.
