Technical Field

[0001] This utility model relates to the field of medical devices, specifically an anti-dislodgement device for clinical biliary drainage tubes. Background Technology

[0002] A biliary drainage tube is a medical device used to drain bile, usually after biliary surgery, to relieve bile duct pressure, prevent infection, and promote postoperative recovery.

[0003] Existing clinically used biliary drainage tubes can be fixed with a Silex clamp. Some biliary drainage tubes have perforated ear plates, which facilitate fixation. Silex clamps can be used in conjunction with these ear plates. However, some biliary drainage tubes do not have ear plates. If a Silex clamp is used in such cases, it can easily lead to excessive deformation of the drainage tube, affecting normal drainage. Furthermore, because the tube is long, it is prone to swaying and scratching the patient's skin. Another common method is to tie a rope to the other end of the drainage tube. However, this method does not allow for adjustment of the tightness of the biliary drainage tube.

[0004] Therefore, a novel anti-dislodgement device for clinical biliary drainage tubes needs to be designed to solve the above problems. Utility Model Content

[0023] Please refer to Figure 1-4As shown, this utility model provides a device to prevent dislodgement of a clinical biliary drainage tube, including a fixing plate 1 for fixing the biliary drainage tube 20. Adjustment grooves are provided on both sides of the fixing plate 1. A positioning post 3 is provided on the fixing plate 1 to be inserted into the adjustment groove. A positioning plate 4 is provided at the tail end of the positioning post 3. A sliding groove 5 is provided on the fixing plate 1 to cooperate with the positioning plate 4. A buckle plate is provided on one side of the fixing plate 1 to cooperate with the positioning post 3. A pull rope 7 for fixing the connector of the biliary drainage tube 20 is provided between the two buckle plates. The buckle plate includes a sleeve 8 and a connecting plate 9. The sleeve 8 is anti-rotationally engaged with the positioning post 3. A recess 10 for winding the pull rope 7 is provided on the outer wall of the sleeve 8. The adjustment groove includes multiple continuous positioning grooves 11 adapted to the positioning post 3.

[0024] The fixing plate 1 is made of medical-grade polypropylene. Adjustment grooves are formed on both sides of the fixing plate 1. Positioning posts 3 are inserted into the adjustment grooves. Positioning plate 4 is fixed to the tail end of the positioning post 3. A sliding groove 5 is formed on one side of the fixing plate 1, allowing the positioning plate 4 to remain fixed within the sliding groove 5. The adjustment groove consists of multiple continuous positioning grooves 11, each cylindrical. Positioning posts 3 can be inserted into the positioning grooves 11, allowing adjustment of the distance between the two positioning posts 3 according to the width of the fixing location of the biliary drainage tube 20. Positioning posts 3 cannot move left or right when inserted into the positioning grooves 11. The buckle plate is integrally injection molded from a sleeve 8 and a connecting plate 9. The sleeve 8 can be inserted onto the positioning post 3. The sleeve 8 and the positioning plate 4 clamp the fixing plate 1 in the middle, preventing the fixed biliary drainage tube 20 from detaching. Positioning plate 4 prevents positioning post 3 from rotating and fixes biliary drainage tube 20. Both ends of pull rope 7 are fixed to sleeve 8. The middle part of sleeve 8 can be wrapped around the connector of biliary drainage tube 20. The sleeve 8 and positioning post 3 cooperate to prevent rotation and adjust the tightness between the fixing part and the connector, preventing the drainage tube from loosening and avoiding damage to nearby skin tissue when the patient moves. The head of positioning post 3 is preferably hexagonal, and the inside of sleeve 8 is also hexagonal to improve the accuracy of tightness adjustment. Recess 10 is opened on the outer wall of sleeve 8. Excess pull rope 7 can be wrapped around recess 10 to prevent loosening. Drainage tube tee connector 50 is part of biliary drainage tube 20.

[0025] Specifically, a clamping plate 12 is provided on one side of the positioning post 3, and an arc-shaped notch 13 is provided on one side of the clamping plate 12. The clamping plate 12 is integrally formed on one side of the middle part of the positioning post 3, and the notch 13 is opened on one side of the clamping plate 12. The notch 13 is arc-shaped and can clamp and fix the body of the bile duct drainage tube 20, which is suitable for clamping to different parts of the bile duct drainage tube 20.

[0026] The fixing plate 1 has a protective pad 14 on one side, which is attached to the back of the fixing plate 1. The other side of the protective pad 14 can be attached to the skin, thus preventing the fixing plate 1 from directly contacting the patient's skin tissue.

[0027] Working principle: When fixing the biliary drainage tube 20, first determine the fixing position of the device, then remove the buckle plate and attach the protective pad 14 to the patient's skin. Insert the positioning post 3 into the appropriate positioning groove 11, and place the biliary drainage tube 20 between the two positioning posts 3. When there is an ear plate 30 at the required fixing location, use the positioning post 3 to pass through the hole on the ear plate 30. When there is no ear plate 30 at the required fixing location, rotate the positioning post 3 and use the clamp 12 on the side of the positioning post 3 to clamp the biliary drainage tube 20. Then, use the sleeve 8 on one of the buckle plates to insert into the head of the positioning post 3 so that the middle of the pull rope 7 passes around the joint of the drainage tube. Rotate the sleeve 8 according to the tightness. The rotation of the sleeve 8 can release or rewind the pull rope 7. After adjusting to the appropriate tightness, insert the cover sleeve 8 into the other positioning post 3.
