[0026] Through the above design, when the drainage tube 11 and the drainage bottle 12 are connected and communicated by using the device, first, according to the inner diameter size and the model of the pipeline on the drainage tube 11 and the drainage bottle 12, two joint pipes 8 with expansion rings 10 corresponding to the size are selected, after the selection is completed, the conical tube 9 on the outer end of one of the joint pipes 8 is inserted into the pipeline on the drainage bottle 12, until the pipeline on the drainage bottle 12 is sleeved on the joint pipe 8 beyond the pair of expansion rings 10, then the joint pipe 8 is threadedly connected to the threaded head 2 on the right side of the connecting pipe 1, after the connection is completed, at this time, the fixed ring 5 on the right side of the connecting pipe 1 is moved to the position of the pair of expansion rings 10 on the joint pipe 8, so that the fixed ring 5 on the right side is sleeved and abuts on the outer wall of the pipeline on the drainage bottle 12, then the drainage tube 11 is sleeved and installed on the other joint pipe 8 according to the same method, and the joint pipe 8 is threadedly connected to the threaded head 2 on the left side of the connecting pipe 1, at the same time, the fixed ring 5 on the left side is moved and adjusted to be sleeved and abutted on the outer wall of the drainage tube 11, so that the drainage tube 11 and the drainage bottle 12 are connected and communicated, and the pipeline on the drainage tube 11 and the drainage bottle 12 of different sizes and models can be effectively connected and communicated due to the multiple joint pipes 8 with different size expansion rings 10.
[0027] Reference Figure 1 , 2, 3, 4, the inner circle of the inflatable ring 3 is fixedly installed with a middle plate 13, the middle plate 13 is connected with a plurality of air pipes 14 in a circumferential direction, the corrugated pipe 4 is located below the middle plate 13 inside the inflatable ring 3, the top of the middle plate 13 is fixedly connected with a sealing plug 15 abutting against the inner wall of the inflatable ring 3 through a reset spring, the top of the inflatable ring 3 is provided with a plug hole 16 above the sealing plug 15, the inner wall of the inflatable ring 3 is provided with a sealing ring 17 at the position of the plug hole 16, and the top of the sealing plug 15 is fixedly installed with a cross rod 18 with a cross-shaped top.
[0028] Through the above design, after the drainage tube 11 and the drainage bottle 12 are connected, medical staff can hold the syringe and insert the injection head into the inflatable ring 3 from the plug hole 16 in the top of the inflatable ring 3, and the outer periphery of the injection head is abutted and sealed by the sealing ring 17. When the injection head abuts against the cross rod 18, the injection head is continuously inserted into the inflatable ring 3, so that the injection head extrudes the sealing plug 15 to compress the reset spring and moves downward, so as to open the passage of the inflatable ring 3. Then, the medical staff press the injection rod of the syringe to discharge the air in the syringe into the inflatable ring 3, and the air entering the inflatable ring 3 flows through the air pipes 14 on the middle plate 13 and the corrugated pipe 4 and is discharged into the air bag ring 6 on the inner ring of the fixed ring 5, so that the air bag ring 6 inflates and expands. Since the two fixed rings 5 are respectively sleeved on the outer walls of the pipes of the drainage tube 11 and the drainage bottle 12, the inflated air bag ring 6 cooperates with the joint pipe 8 to extrude and fix the pipes of the drainage tube 11 and the drainage bottle 12, and a pair of expansion rings 10 on the outer wall of the joint pipe 8 limits the two sides of the inflated air bag ring 6, so that the pipes of the drainage tube 11 and the drainage bottle 12 are firmly and sealingly connected to the joint pipe 8, thereby preventing the pipes from being separated. In addition, it should be explained that when the air bag ring 6 is inflated, the medical staff can slowly pull out the syringe from the top of the inflatable ring 3. When the cross rod 18 loses the abutment of the injection head of the syringe, the sealing plug 15 abuts against the inner wall of the inflatable ring 3 again under the rebound of the reset spring to prevent the air bag ring 6 from deflating, so as to always maintain the inflation state of the air bag ring 6. After the reset of the sealing plug 15, the syringe can be completely pulled out from the inflatable ring 3. When the drainage tube 11 and the drainage bottle 12 need to be separated, the syringe is reinserted and deflated according to the same principle, and then each part is removed one by one, which is convenient, fast and practical.
[0029] The implementation principle of the embodiment of the application is:
[0030] When the drainage tube 11 and the drainage bottle 12 are connected by using the device, two joint pipes 8 with the expansion rings 10 corresponding to the size of the pipe of the drainage tube 11 and the drainage bottle 12 are selected first. Then, the tapered pipe 9 at the outer end of one of the joint pipes 8 is inserted into the pipe of the drainage bottle 12 until the pipe of the drainage bottle 12 is sleeved on the joint pipe 8 through the expansion rings 10. Then, the joint pipe 8 is screwed on the threaded head 2 on the right side of the connecting pipe 1. After the connection, the fixed ring 5 on the right side is adjusted to the position of the expansion rings 10 on the joint pipe 8, so that the fixed ring 5 on the right side is sleeved on the outer wall of the pipe of the drainage bottle 12. Then, the drainage tube 11 is sleeved on the other joint pipe 8 in the same way, and the joint pipe 8 is screwed on the threaded head 2 on the left side of the connecting pipe 1. At the same time, the fixed ring 5 on the left side is adjusted to be sleeved on the outer wall of the drainage tube 11, so that the drainage tube 11 and the drainage bottle 12 are connected.
[0031] After the drainage tube 11 and the drainage bottle 12 are connected, the medical staff can hold the syringe and insert the injection head into the inflation ring 3 through the insertion hole 16 at the top of the inflation ring 3. At this time, the outer circumference of the injection head is sealed by the sealing ring 17. When the injection head abuts against the cross rod 18, the injection head is further inserted into the inflation ring 3, so that the injection head is pressed to compress the reset spring through the cross rod 18, so as to open the passage of the inflation ring 3. Then, the medical staff presses the injection rod of the syringe to discharge the air in the syringe into the inflation ring 3. The air in the inflation ring 3 flows through the air pipe 14 on the middle plate 13 and the corrugated pipe 4 into the air bag ring 6 in the inner ring of the fixed ring 5, so that the air bag ring 6 is inflated. At this time, the inflated air bag ring 6 is fixed on the pipe of the drainage tube 11 and the drainage bottle 12 through the joint pipe 8 and the expansion rings 10 on the outer wall of the joint pipe 8, so that the pipe of the drainage tube 11 and the drainage bottle 12 is firmly and sealingly connected on the joint pipe 8, thereby preventing the pipe from being loosened.
[0032] In addition, it is also necessary to explain that when the air bag ring 6 is inflated, the medical staff can slowly pull out the syringe from the top of the inflation ring 3, at this time when the cross rod 18 loses the abutment of the injection head of the syringe, the sealing plug 15 will be abutted on the inner wall of the inflation ring 3 under the rebound of the reset spring to prevent the air bag ring 6 from deflating, so as to always keep the inflation state of the air bag ring 6, after the reset of the sealing plug 15, the syringe can be completely pulled out from the inflation ring 3, when it is needed to separate the drainage tube 11 and the drainage bottle 12, according to the same principle as above, the syringe is reconnected and deflated, and then each part is removed one by one, which is convenient, fast and practical.
[0033] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the technical solution of the present application, and any equivalent embodiments with equivalent changes or modifications are still within the scope of the present application.
