Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a liver and gallbladder nursing drainage device. Background Art

[0002] Hepatobiliary surgery mainly studies acute liver failure caused by hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and severe hepatitis, which are major diseases that threaten health. Percutaneous hepatobiliary puncture and drainage under the guidance of ultrasound or X-ray fluoroscopy is a common treatment measure for obstructive jaundice caused by liver cancer, hepatocellular carcinoma and pancreatic cancer. After hepatobiliary surgery, bile will accumulate inside the body. Hepatobiliary drainage is to drain the accumulated bile in the human body to the outside of the body through a drainage device to reduce the pressure in the bile system.

[0003] The existing drainage device is used to draw out the bile accumulated in the patient's body into a collection bag. When the collection bag stores a sufficient amount of bile and needs to be disassembled and replaced, the pipe opening in the drainage device connected to the collection bag is still in an open state. At this time, medical staff are required to take additional tools to seal it. This is not only troublesome, but the bile will also flow out during the process of taking the tools, causing pollution. Therefore, it is necessary to design a hepatobiliary care drainage device. Utility Model Content

[0021] Reference Figure 1-4 The utility model provides a liver and gallbladder care drainage device, including a guide tube, the upper end of the guide tube is fixedly connected with a conical head 2, the lower end of the guide tube is fixedly connected with a connecting tube 3, the lower end of the connecting tube 3 is fixedly connected with a drainage pipe head 12, the circumferential surface of the drainage pipe head 12 is fixedly connected with a fixing plate 6, the circumferential surface of the drainage pipe head 12 is threadedly connected with a connecting head 5, the connecting head 5 is located at the lower end of the fixing plate 6, the lower end of the connecting head 5 is fixedly connected with a negative pressure bag 4, the internal top end of the negative pressure bag 4 is installed with a jacking assembly, and the interior of the drainage pipe head 12 is installed with a sealing assembly.

[0022] The lifting assembly includes a connecting tube 18, a fixing frame 7, a fixing rod 8 and a pushing block 9. The inner top of the negative pressure bag 4 is fixedly connected to the connecting tube 18, the connecting tube 18 is located directly below the discharge pipe head 12, the inner wall of the connecting tube 18 is fixedly connected to the fixing frame 7, the upper end of the fixing frame 7 is fixedly connected to the fixing rod 8, and the upper end of the fixing rod 8 is fixedly connected to the pushing block 9.

[0023] The sealing assembly includes a sealing ball 11, a sealing ring 10, an annular support seat 13, a fixed cylinder 14, a moving rod 15, a spring 16 and a stopper 17. The inner wall of the discharge pipe head 12 is fixedly connected with the annular support seat 13 and the sealing ring 10. The sealing ring 10 is located at the lower end of the annular support seat 13. The interior of the annular support seat 13 is fixedly connected with the fixed cylinder 14. The interior of the fixed cylinder 14 is slidably connected with the moving rod 15 and the stopper 17. The stopper 17 is fixedly installed at the upper end of the moving rod 15. A spring 16 is arranged inside the fixed cylinder 14. One end of the spring 16 is fixedly connected to the fixed cylinder 14. The other end of the spring 16 is fixedly connected to the stopper 17. The lower end of the moving rod 15 is fixedly connected with the sealing ball 11, and the sealing ball 11 is sealed with the sealing ring 10.

[0024] During operation, with the cooperation of the lifting assembly and the sealing assembly, after the negative pressure bag 4 is removed, the negative pressure bag 4 will separate from the discharge pipe head 12 with the lifting assembly, and then the sealing ball 11 in the sealing assembly will move downward under the action of its own gravity and the spring 16. At this time, the sealing ball 11 will move downward under the action of its own gravity and the spring 16, so that with the cooperation of the sealing ball 11 and the sealing ring 10, the discharge pipe head 12 can be closed. Since the discharge pipe head 12 can be automatically closed immediately during the removal of the negative pressure bag 4, it is not only more convenient, but also can prevent bile from flowing out to the outside, thereby reducing pollution.

[0025] Furthermore, the push block 9 is located directly below the sealing ball 11 , and the diameter of the push block 9 is smaller than the diameter of the sealing ball 11 .

[0026] During operation, with the installation of the negative pressure bag 4, the push block 9 can accurately push the sealing ball 11 upwards, so that the sealing ball 11 moves away from the sealing ring 10. At this time, the moving rod 15 will also move toward the inside of the fixed tube 14. At the same time, the spring 16 is squeezed. Due to the separation of the sealing ball 11 from the sealing ring 10, the bile flowing out along the guide tube, the connecting tube 3 and the drainage pipe head 12 can be smoothly discharged into the negative pressure bag 4 through the sealing ring 10.

[0027] Furthermore, the diameter of the stopper 17 is larger than the diameter of the moving rod 15 , and a through hole is formed on the lower end surface of the fixing cylinder 14 for the moving rod 15 to slide, and the diameter of the through hole matches the diameter of the moving rod 15 , and the diameter of the through hole is smaller than the diameter of the stopper 17 .

[0028] During operation, under the action of the stopper 17 , the moving rod 15 is not easily separated from the fixing tube 14 .

[0029] Furthermore, two connecting tubes 3, negative pressure bags 4, connecting heads 5, fixing plates 6, drainage pipe heads 12, lifting assemblies and sealing assemblies are provided and symmetrically distributed at the left and right ends of the drainage tube 1, and the two connecting tubes 3 are interconnected with the drainage tube 1.

[0030] During operation, when the conical head 2 is inserted into the patient's liver and gallbladder, the liquid flowing out of the patient's liver and gallbladder can follow the catheter 1, enter the two connecting tubes 3, and then follow the two drainage pipe heads 12 into the two negative pressure bags 4, so that more bile can be stored and the frequency of replacing the negative pressure bags 4 can be reduced.

[0031] Furthermore, the outer surfaces of the sealing ball 11 , the sealing ring 10 , the moving rod 15 , the fixing tube 14 and the annular supporting seat 13 are all sprayed with anti-corrosion materials.

[0032] During operation, the corrosion resistance of the sealing ball 11, the sealing ring 10, the moving rod 15, the fixed tube 14 and the annular support seat 13 can be improved, and the probability of the sealing ball 11, the sealing ring 10, the moving rod 15, the fixed tube 14 and the annular support seat 13 being damaged due to corrosion can be reduced.

[0033] Furthermore, a material drop hole is formed on the upper end surface of the annular support seat 13 , and the material drop hole is communicated with the liquid discharge pipe head 12 .

[0034] During operation, the liquid flowing along the connecting pipe 3 toward the discharge pipe head 12 can smoothly flow into the discharge pipe head 12 along the drop holes on the annular support seat 13 and finally fall into the negative pressure bag 4 .

[0035] Working principle:

[0036] When it is necessary to disassemble and replace the negative pressure bag 4, first rotate the negative pressure bag 4 and the connecting head 5 along the drainage pipe head 12 until the connecting head 5 is separated from the drainage pipe head 12. At this time, the disassembly of the negative pressure bag 4 is completed. During the disassembly process, the push block 9 gradually moves downward with the rotation of the negative pressure bag 4 and gradually moves away from the sealing ball 11. When the negative pressure bag 4 is completely disassembled, the push block 9 will also be completely separated from the sealing ball 11. At this time, the sealing ball 11 will move downward under the action of its own gravity and the spring 16. In this way, the sealing ball 11 and the sealing ring 10 cooperate with each other to play the role of sealing the drainage pipe head 12. Since the drainage pipe head 12 can be automatically and immediately closed during the process of disassembling the negative pressure bag 4, it is not only more convenient, but also can prevent bile from flowing out to the outside, thereby reducing pollution.
