Description

Technical Field

[0001] The invention relates to the field of medical connecting tubes, in particular to a connecting tube of a PTCD composite drainage tube. Background Art

[0002] PTCD drainage tube is the drainage tube used in percutaneous transhepatic choledochal drainage. It means that with the help of color ultrasound or CT, the doctor uses a special puncture needle to percutaneously puncture the patient's abdominal cavity, puncture the liver to reach the bile duct, and perform bile drainage. It is clinically used for preoperative preparation, drainage decompression, palliative treatment, and other functions.

[0003] When working, the PTCD drainage connecting tube usually acts as a transition between the two ends of the catheter. When in use, it drains the internal bile. In this process, a puncture needle will be used to pierce the patient's abdominal cavity. The tail end of the puncture needle is connected to a wire rope, and the wire rope needs to be dragged to remove it later. Since the puncture needle is dangerous and there is a lack of effective fixing protection measures, the drainage connecting tube itself needs to be adhered to the patient's skin with the help of external tools such as medical tape to maintain the stability of the infusion. Therefore, a connecting tube of the PTCD composite drainage tube is needed. Summary of the invention

[0016] By setting a patterned torsion shaft, rotational friction is increased to prevent slipping. By setting a sleeve, the patterned torsion shaft rotates to drive the sleeve to rotate. The rotation of the sleeve causes the arc-shaped slide groove to rotate, which drives the overall position of the convex shaft and the push rod to change. The control ball controls and blocks the internal flow in the first through hole or the second through hole, thereby achieving blocking. When the blocking surface of the control ball is larger, the flow of bile is slowed down, and conversely, the outflow of bile is accelerated. The advantage of this is that precise control of the flowing liquid in the first through hole can be achieved to keep the patient in a comfortable state when the liquid flows.

[0017] The excess wire is wrapped around the surface of the infusion tube. The used puncture needle is placed in the syringe and fixed. The folding plate is rotated to reset it. At this time, the L-shaped card plate is connected to the U-shaped plate, so that the groove and the triangular protrusion are engaged and matched to position and fix the puncture needle to prevent other safety hazards.

[0031] By setting a first O-ring 706, the first O-ring 706 is pressed and matched with the surface of the plug-in tube 5 to perform a sealing operation. By setting multiple fastening soft rings 707, the multiple fastening soft rings 707 are pressed and contacted with the surface of the plug-in tube 5, the friction is increased and secondary sealing is performed to prevent the plug-in tube 5 from detaching from the tapered plug-in tube 702.

[0032] As a preferred implementation in this embodiment, the inner wall of the connecting body 1 is rotatably connected with a sleeve 719, the surface of the sleeve 719 is fixedly connected with a patterned torsion shaft 703, and the inner wall of the sleeve 719 is provided with a pair of arc-shaped sliding grooves 720.

[0033] By setting the patterned torsion shaft 703, the rotational friction is increased to prevent slipping. By setting the sleeve 719, the patterned torsion shaft 703 rotates to drive the sleeve 719 to rotate, and the rotation of the sleeve 719 drives the push rod 717 to move. By setting the arc-shaped slide groove 720, space is given for the convex shaft 721 to move around, and the rotation of the arc-shaped slide groove 720 drives the overall position of the convex shaft 721 and the push rod 717 to change.

[0035] By setting the top rod 717 and installing the fixed control ball 718, the internal flow in the first through hole 710 or the second through hole 709 can be controlled and blocked, thereby achieving blocking. When the blocking surface of the control ball 718 is large, the flow of bile is slowed down, otherwise, the outflow of bile is accelerated.

[0036] As a preferred implementation in this embodiment, the inner wall of the connecting cylinder 3 is rotatably connected to a folding plate 705 , one side of the folding plate 705 is fixedly connected to a syringe 722 , and one end of the folding plate 705 is fixedly connected to a toggle plate 714 .

[0037] By setting the folding plate 705, the installation and fixation of the syringe 722 on one side is achieved. By setting the syringe 722, the puncture needle is placed and stored. By setting the toggle plate 714, the operator can use the toggle plate 714 to drive the folding plate 705 to rotate together to take out the needle in the syringe 722.

[0038] In this embodiment, a U-shaped plate 711 is fixedly connected to the inner wall of the connecting tube 3, a triangular protrusion 712 is fixedly connected to the inner wall of the U-shaped plate 711, an L-shaped clamping plate 713 is fixedly connected to one side of the folding plate 705, and a groove 724 is provided on the surface of the L-shaped clamping plate 713, which is adapted to the triangular protrusion 712.

[0039] By setting a U-shaped plate 711, installing and fixing the triangular protrusion 712, and setting an L-shaped clamping plate 713, the L-shaped clamping plate 713 has a certain toughness and can be completely deformed. When the L-shaped clamping plate 713 is clamped in the corresponding U-shaped plate 711, the groove 724 is engaged with the triangular protrusion 712 to keep the folding plate 705 stable after rotation.

[0040] In this embodiment, a friction sleeve 726 is fixedly connected to the surface of the connecting body 1 , and the patterned torsion shaft 703 is in frictional contact with the surface of the friction sleeve 726 .

[0041] By providing the friction sleeve 726 , the patterned torsion shaft 703 is twisted so that after the patterned torsion shaft 703 stops, it remains stable and does not rotate due to the surface contact with the friction sleeve 726 .

[0042] In this embodiment, the control ball 718 is adapted to the inner wall of the first through hole 710, the diameter of the second through hole 709 is larger than the diameter of the first through hole 710, the surface of the driving shaft 704 is fixedly connected with a second O-ring 723, and the inner wall of the connecting body 1 is provided with an annular groove 725, and the second O-ring 723 is adapted to the inner wall of the annular groove 725.

[0043] By setting the annular groove 725, space is provided for the installation of the second O-ring 723. By setting the second O-ring 723, liquid is prevented from flowing out when the driving shaft 704 is rotated. By setting the control ball 718 to adapt to the inner wall of the first through hole 710, precise control of the flowing liquid in the first through hole 710 is achieved to keep the patient in a comfortable state when the liquid flows.

[0044] The working principle of the present invention is as follows: a connecting tube of a PTCD composite drainage tube. When the user uses it, the operator first toggles the toggle plate 714 to rotate and open the folding plate 705, takes out the puncture needle in the syringe 722, and performs acupuncture on the patient's part. After the acupuncture is completed, the puncture needle is pulled out through the string connected to the puncture needle, and one end of the infusion tube 4 is inserted into the patient's abdomen. The excess string is wound around the surface of the infusion tube 4, and the used puncture needle is placed in the syringe 722 for fixing, and the folding plate 705 is rotated to reset it, and at this time, the L-shaped The clamping plate 713 is clamped in the U-shaped plate 711, so that the groove 724 is clamped with the triangular protrusion 712 to maintain stability and prevent the needle and thread from being outside and causing danger. When the operator needs to adjust the flow of bile in the connecting body 1, the handle 2 can be twisted and rotated. The rotation of the handle 2 drives the driving shaft 704 to rotate, and the rotation of the driving shaft 704 drives the adjusting disk 708 to rotate. The adjusting disk 708 rotates to change the direction of the second through hole 709 or the first through hole 710, so that the liquid flows out from one of the holes. When the flow speed of the liquid in the connecting body 1 needs to be slowed down, the operator The author rotates the pattern torsion shaft 703, and the rotation of the pattern torsion shaft 703 drives the sleeve 719 to rotate. The rotation of the sleeve 719 drives the convex shaft 721 to move and adjust the position in the arc-shaped slide groove 720. At this time, the convex shaft 721 changes the distance of the push rod 717 in the sleeve 719, so that the push rod 717 originally located in the sleeve 719 extends and lengthens, and the control ball 718 blocks the intersection of the second through hole 709 and the first through hole 710. The liquid is blocked and its flow is slowed down. At this time, the rotation angle of the control pattern torsion shaft 703 is adjusted to control the flow of the liquid. To ensure that the patient is in a comfortable state during the drainage, the surface of the friction sleeve 726 is in friction contact with the surface of the patterned torsion shaft 703, remains stable and does not rotate. When in use, the operator tears off the dust protection sticker 716, and can stick the adhesive plate 715 to the patient's skin to keep it fixed to the skin and prevent it from falling off. With the above structure, after the puncture needle is used, the puncture needle is positioned and fixed to prevent other safety hazards. At the same time, when in use, the dust protection sticker 716 is torn off and the adhesive plate 715 is stuck to the patient's skin, which is quick and convenient.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
