Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a temporary vascular shunt device. Background Technology
[0002] Temporary vascular shunt is a temporary measure taken during vascular injury or surgery to restore or maintain blood flow in order to ensure tissue perfusion and oxygenation. Specifically, it involves establishing a temporary pathway at both ends of the injured blood vessel, allowing blood to bypass the site of injury and continue flowing, thereby restoring blood supply.
[0003] During the temporary shunt procedure, Dr. Zhang needs to clean the damaged segment or end of the blood vessel down to the undamaged intima, then insert a shunt tube to establish a temporary access. The connection between the shunt tube and the blood vessel can loosen due to patient movement or blood flow pressure, resulting in poor fixation. In some cases (such as when the patient is experiencing continuous blood loss or when heparin is injected to prevent blood clotting), temporary shunts require the infusion of fresh blood or medication, which is troublesome and increases patient discomfort with a second puncture. Utility Model Content
[0004] This invention addresses the problem that the connection between the shunt tube and the blood vessel can become loose due to patient movement or blood flow pressure, resulting in poor fixation. In some cases (such as when the patient is experiencing continuous blood loss or when heparin is injected to prevent blood clotting), temporary shunts require the infusion of fresh blood or medication, which is troublesome and increases patient discomfort due to the need for a second puncture. This invention provides a temporary vascular shunt device.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a temporary vascular shunt device, including a medical tee, several catheters, and several sets of vascular connection components. The medical tee includes a main body, which is connected to two mutually perpendicular connecting tubes. One side of the main body is connected to a branch tube with a quick connector. The two ends of the catheters are respectively provided with an outer conical connector and a cylindrical connector. The outer conical connector is inserted into the connecting tube. The vascular connection components include an intermediate sleeve and a vascular connector. The intermediate sleeve is sleeved on the outside of the cylindrical connector and rotatably connected to the cylindrical connector. The intermediate sleeve is threadedly connected to the vascular connector.
[0006] As an improvement, the main body is a transparent shell, and the branch pipe is equipped with a valve.
[0007] As an improvement, the outer diameter of the vascular connector is the same as that of the cylindrical connector.
[0008] As an improvement, the outer side of the cylindrical connector is provided with several insertion holes along the circumference, and the side of the blood vessel connector near the cylindrical connector is provided with several rods along the circumference, and the rods are inserted into the insertion holes.
[0009] As an improvement, the medical tee is further provided with several matching caps, a first protective sleeve, and a second protective sleeve. The caps are threaded to the connecting pipe, the first protective sleeve is fitted onto the outside of the external conical connector, and the second protective sleeve is fitted onto the outside of the branch pipe.
[0010] The advantages of this utility model are: 1. The connection of the diversion pipeline is stable. Unlike the general plug-in or press-fit connection, the blood vessel connector used in this utility model has multiple rods. When connecting, the end of the blood vessel is in an outward-facing state. After the rods and the insertion holes are positioned and plugged in, the middle sleeve tightly connects and fixes the cylindrical connector and the blood vessel connector together. The blood vessel will not be stretched by strong external force and will not be able to detach, resulting in high stability.
[0011] 2. It is easy to operate and has an auxiliary infusion function. Unlike general medical reversing three-way valves, which require pathway switching for infusion, the medical three-way valve used in this utility model can connect the pipeline and perform blood transfusion and infusion operations while maintaining blood vessel connectivity.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.
[0017] Combined with appendix Figure 1 , Figure 2A temporary vascular shunt device includes a medical tee 1, several catheters 2, and several sets of vascular connection components. The medical tee 1 includes a main body 3, which is connected to two mutually perpendicular connecting tubes 4. One side of the main body 3 is connected to a branch tube 5 with a quick connector. The two ends of the catheters 2 are respectively provided with an outer conical connector 6 and a cylindrical connector 7. The outer conical connector 6 is inserted into the connecting tube 4. The vascular connection components include an intermediate sleeve 8 and a vascular connector 9. The intermediate sleeve 8 is sleeved on the outside of the cylindrical connector 7 and is rotatably connected to the cylindrical connector 7. The intermediate sleeve 8 is threadedly connected to the vascular connector 9. The medical tee 1 is also provided with several matching caps 13, protective sleeve one 14, and protective sleeve two 15. The caps 13 are threadedly connected to the connecting tube 4. The protective sleeve one 14 is sleeved on the outside of the outer conical connector 6, and the protective sleeve two 15 is sleeved on the outside of the branch tube 5.
[0018] Among them, the medical three-way valve 1, catheter 2, and vascular connection assembly are disposable items and are sealed in packaging bags after being sterilized. After opening, the cap 13, protective sleeve 14, and protective sleeve 2 15 can be removed for use as needed.
[0019] The main body 3 is a transparent shell, and the branch tube 5 is equipped with a valve 10. The transparent main body 3 allows clear observation of the blood flow status inside the medical three-way valve 1. The branch tube 5 can be quickly connected to an external pipeline as a pipeline connector for external blood supply or infusion, allowing infusion to be performed directly at the blood vessel connection point, replacing secondary puncture infusion.
[0020] Combined with appendix Figure 3 The outer diameter of the vascular connector 9 is the same as that of the cylindrical connector 7. The outer side of the cylindrical connector 7 is provided with several insertion holes 11 along the circumference. The side of the vascular connector 9 near the cylindrical connector 7 is provided with several rods 12 along the circumference. The rods 12 are inserted into the insertion holes 11.
[0021] The vascular connector 9 can be fitted onto the outside of the fractured blood vessel wall. After the hemostat closes the blood vessel, the probe 12 passes through the tube wall at the end of the blood vessel. At this time, the end of the blood vessel is slightly turned outward. The probe 12 is inserted into the insertion hole 11 during the connection of the vascular connector 9 and the intermediate sleeve 8, and the blood vessel flow path is connected to the catheter 2. It should be noted that when connecting the vascular connector 9 and the intermediate sleeve 8, the vascular connector 9 should be clamped with forceps and the intermediate sleeve 8 should be rotated to make the connection.
[0022] In specific implementation of this invention, the port of the blood vessel requiring temporary diversion is sealed using vascular clamps. The cap is removed, the outer conical connector is inserted into the connecting tube, the vascular connector is fitted onto the end of the blood vessel, and the end of the blood vessel is turned outward so that the probes are inserted one by one. The vascular connector is connected to the intermediate sleeve and the probes are fully inserted into the insertion hole. The blood vessel is sealed between the cylindrical connector and the vascular connector. When blood transfusion or infusion is required, the branch tube is connected to the infusion tube and the valve is opened.
[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
