[0031] Please see Figures 1 to 9 The image shows an abdominal drainage device according to an embodiment of the present invention, comprising an abdominal catheter 10 for extracting ascites from a patient, a drainage bag 20 for collecting ascites from a patient, and a connecting assembly 30 connecting the abdominal catheter 10 and the drainage bag 20. The drainage bag 20 includes a drainage catheter and a bag body. The abdominal catheter 10 includes a first tube body 11 and a first connecting end 15 connected to the first tube body 11. The first connecting end 15 includes a sealing body 12. The drainage catheter includes a second tube body 21 and a second connecting end 25 connected to the second tube body 21. The second connecting end 25 includes a stepped section 22 with a stepped design. The side of the second connecting end 25 near the second tube body 21 has a flat portion 24. The connecting assembly 30 includes a connecting tube 31 and a connecting part 24 disposed near the first tube body 21. A third connecting end 32 at one end of a connecting end 15 and a fourth connecting end 33 at one end of the connecting pipe 31 near the second connecting end 25. The third connecting end 32 includes a plurality of clamping pieces 36 arranged in a ring array. A slot 34 is formed between the plurality of clamping pieces 36. A first through hole 42 for the first connecting end 15 to enter is formed inside the plurality of clamping pieces 36. Nuts 37 are provided on the plurality of clamping pieces 36. The clamping pieces 36 are threadedly connected to the nuts 37. The clamping pieces 36 are used to clamp the sealing body 12. The fourth connecting end 33 is recessed on the side near the second connecting end 25 to form a second through hole 45 for the second connecting end 25 to enter. The second through hole 45 is provided with an abutting platform 46 that abuts against the stepped section 22 and a clamping structure 41 for pressing the flat part 24.

[0032] Understandably, this utility model, by providing a connecting component 30 between the abdominal catheter 10 and the drainage bag 20, can more conveniently and securely connect the abdominal catheter 10 and the drainage bag 20, preventing leakage and loosening that occur with ordinary connecting tubes. Specifically, when it is necessary to connect the abdominal catheter 10 and the drainage bag 20, the sealing body 12 is inserted into the first through hole 42 formed by multiple clamps 36, and then the nut 37 is turned in the direction of the sealing body 12. Because there are slots 34 between the clamps 36, the clamps 36 are not purely rigid but have a certain degree of elasticity. The rotation of the nut 37 will cause the clamps 36 to clamp the sealing body 12, thus... The abdominal catheter 10 and the connecting component 30 are fixed. Then, the second connecting end 25 is inserted into the second through hole 45 until the abutting platform 46 in the second through hole 45 abuts against the stepped section 22. Then, the drainage bag 20 and the connecting component 30 are fixed by fixing the flat part 24 through the clamping structure 41. This design structure can conveniently fix the abdominal catheter 10 and the drainage bag 20. Since the production line of the abdominal catheter 10 and the drainage bag 20 is already very mature, this utility model only improves the connecting component 30 without changing the structure of the abdominal catheter 10 and the drainage bag 20. It is better adapted to the current technical situation and can be used immediately.

[0033] Furthermore, an installation groove 48 is provided inside the second through hole 45. The clamping structure 41 includes a rotating shaft 50 disposed in the installation groove 48, an extrusion plate 47 rotatably connected to the rotating shaft 50, and a torsion spring 49 connecting the extrusion plate 47 and the groove wall of the installation groove 48.

[0034] Understandably, when it is necessary to connect the second connecting end 25 and the fourth connecting end 33, the pressing plate 47 is flipped outward, and the second connecting end 25 is inserted into the second through hole 45 until the stepped section 22 abuts against the abutting platform 46. At this time, the flat part 24 is just at the opening of the second through hole 45. Then the pressing plate 47 is released. Due to the restoring force of the torsion spring 49, the pressing plate 47 will press against the flat part 24. It is necessary to pull the second connecting end 25 more to pull it out, which can prevent accidental loosening and facilitate disassembly.

[0035] Preferably, the nut 37 has an internal thread 38 on its inner wall, and the multiple clamping pieces 36 have external threads 35 on their outer walls that cooperate with the internal thread 38.

[0036] Furthermore, the first connecting end 15 also includes a sealing sleeve 13 disposed on the side of the sealing body 12 near the third connecting end 32. The sealing sleeve 13 has a first channel 14 that communicates with the first tube body 11. The first through hole 42 has a second channel 43 that cooperates with the first channel 14. The stepped section 22 has a third channel 23 that communicates with the second tube body 21. The second through hole 45 has a fourth channel 44 that cooperates with the third channel 23. The connecting pipe 31 has a fifth channel 52 that communicates with the second channel 43 and the fourth channel 44.

[0037] Understandably, the patient's ascites will pass sequentially through the first tube 11, the first orifice 14, the second orifice 43, the fifth orifice 52, the fourth orifice 44, the third orifice 23, and the second tube 21. The diameter of the second orifice 43 can be larger than the diameter of the first orifice 14 to prevent ascites from overflowing when it flows from the first orifice 14 into the second orifice 43. Similarly, the diameter of the third orifice 23 can be larger than the diameter of the fourth orifice 44 to prevent ascites from overflowing when it flows from the fourth orifice 44 into the third orifice 23.

[0038] Furthermore, the connecting pipe 31 is also provided with a drug injection channel 39 that communicates with the fifth channel 52. The side of the connecting pipe 31 near the second connecting end 25 is provided with a drug injection port that communicates with the drug injection channel 39. A cap 40 is detachably provided on the drug injection port.

[0039] Understandably, when draining ascites, it is necessary to inject medication into the patient's body. To prevent frequent tube removal and replacement, a fifth channel 52 can be set in the connecting tube 31, and a drug injection port can be set. The injection device injects the medication through the drug injection port. The medication will pass through the drug injection channel 39, the fifth channel 52, the second channel 43, the first channel 14, and the first tube 11 in sequence into the patient's body. After use, the cap 40 can be put on.

[0040] In summary, the abdominal drainage device in the above embodiments of this utility model, by setting a connecting component between the abdominal catheter and the drainage bag, can more conveniently and firmly connect the abdominal catheter and the drainage bag, preventing leakage and loosening that occur with ordinary connecting tubes. Specifically, when it is necessary to connect the abdominal catheter and the drainage bag, the sealing body is inserted into the first through hole formed by multiple clamps, and then the nut is turned in the direction of the sealing body. Since there are grooves between the clamps, the clamps are not purely rigid but have a certain degree of elasticity. The rotation of the nut will cause the clamps to clamp the sealing body, thereby fixing the abdominal catheter and the connecting component. Then, the second connecting end is inserted into the second through hole until the abutting platform in the second through hole abuts against the stepped section. Then, the drainage bag and the connecting component are fixed by fixing the flat part through the clamping structure. This design structure can conveniently fix the abdominal catheter and the drainage bag. Since the production line of the abdominal catheter and the drainage bag is already very mature, this utility model only improves the connecting component without changing the structure of the abdominal catheter and the drainage bag, better adapting to the current technical situation and ready to use.
