[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The sterile connecting tube, through the provided main body, tightening ring, and butt-joint tube structure, allows medical staff to directly butt the butt-joint tube to the inner wall of the main body during the process of butt-joining the infusion tube. Since the silicone material has the characteristics of toughness and elasticity, the infusion tube with a larger diameter can also be butt-jointed with the main body, thereby achieving the effect that the connecting tube can butt-join infusion tubes of different diameters, thereby improving the infusion efficiency of medical staff for patients.
[0013] 2. The aseptic connecting tube, through the provided bayonet pin, bayonet hole, butt joint tube and sealing ring structure, can be installed by the user by pulling the bayonet pin to make it separate from the docking ring, so that the main body cannot be contracted by the tightening ring, and the butt joint tube can be inserted deeper into the main body. The cooperation of the butt joint tube and the sealing ring prevents the leakage of the liquid medicine between the main body and the butt joint tube. After the docking is completed, the main body can be tightened again through the cooperation of the tightening ring, bayonet pin and bayonet hole, thereby improving the sealing of the infusion tube after docking with the connecting tube.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-5 The aseptic connecting tube comprises a body 1, a tightening ring 2 is clamped on the outer edge of the body 1, a mounting hole 7 is opened in the middle of the tightening ring 2, a retaining spring 8 and a bayonet 3 are respectively sleeved on the inner wall of the mounting hole 7, a pressure ring 9 is fixedly sleeved on the outer edge of the bayonet 3, a clamping hole 4 is opened on the outer edge of the body 1, a docking tube 5 is fixedly sleeved on the inner wall of the body 1, a sealing ring 6 is fixedly assembled on the inner wall of the body 1, and a docking groove 10 is opened at one end of the docking tube 5 located on the inner wall of the body 1. By setting the sealing ring 6 and the docking groove 10, the sealing ring 6 can be docked with the docking groove 10 after being inserted into the inner wall of the body 1, which can not only further improve the tightness of the connection structure between the docking tube 5 and the body 1, but also reduce the probability of liquid medicine leakage, thereby improving the sealing of the connecting tube.
[0022] See also Figure 4 The inner walls of both ends of the mounting hole 7 are provided with sliding holes, the inner wall of the card hole 4 is fixedly sleeved with a docking ring, and the inner wall of the docking ring is slidably sleeved with the outer edge of the bayonet 3, the top of the pressure ring 9 overlaps the bottom end of the retaining spring 8, and the diameter of the pressure ring 9 is respectively larger than the diameter of the sliding hole and the retaining spring 8, the outer edge of the pressure ring 9 is slidably connected with the inner wall of the mounting hole 7, and the sliding hole can ensure that the user has enough space for movement when pulling the mounting hole 7, so as to facilitate the user to move the tightening ring 2 to continue to push the docking tube 5 to dock with the body 1, thereby improving the sealing between the docking tube 5 and the body 1 after the docking.
[0023] See also Figure 1 The butt-joint pipe 5 is fixedly assembled with the main body 1 by the cooperation of the tightening ring 2, the mounting hole 7, the bayonet pin 3, the bayonet hole 4 and the sealing ring 6. The main body 1 and the sealing ring 6 are respectively made of medical silicone and non-toxic medical rubber. The butt-joint pipe 5 can play the effect of conveying liquid medicine after being docked with the main body 1, and the medical silicone has the characteristics of elasticity and toughness, so that the butt-joint pipes 5 of different diameters can be inserted into the main body 1, so as to achieve the effect of connecting infusion tubes of different specifications and improve the infusion efficiency of medical staff for patients. The non-toxic medical rubber has the characteristics of hardness and elasticity, so that the butt-joint pipe 5 can push the sealing ring 6 to deform after being inserted into the main body 1, and can automatically dock with the docking groove 10 after the docking groove 10 corresponds to the position of the sealing ring 6, thereby improving the sealing between the butt-joint pipe 5 and the main body 1 after the two are docked.
[0024] See also Figure 5The diameter of the sealing ring 6 is equal to the diameter of the docking groove 10. The tightening ring 2 is slidably connected with the outer edge of the main body 1 after the bayonet 3 is separated from the docking ring. The sealing ring 6 and the docking groove 10 can be docked. After the main body 1 is tightened by the tightening ring 2, the sealing ring 6 and the docking groove 10 are tightly fitted, further improving the sealing and stability of the connecting tube after docking the infusion tube.
[0025] See also Figure 3 The number of the card holes 4 and the sealing rings 6 are both several, and the several card holes 4 and the sealing rings 6 are evenly distributed along the outer edge of the main body 1 and the inner wall of the main body 1. The number of the card holes 4 and the sealing rings 6 can ensure that the user can adjust the insertion depth of the docking tube 5 at will after the docking tube 5 is docked with the main body 1, thereby ensuring the stability of the infusion tube during the infusion process.
[0026] See also Figure 4 The end of the bayonet 3 away from the docking ring passes through the inner wall of the mounting hole 7 to the outside of the tightening ring 2. The tightening ring 2 is clamped with the main body 1 through the cooperation of the bayonet 3 and the docking ring. The tightening ring 2 can be fixed by the cooperation of the bayonet 3 and the docking ring, and the tightening ring 2 will tighten the main body 1, so that the inner wall of the main body 1 is tightly fitted to the outer edge of the docking tube 5, thereby achieving the effect of improving the sealing of the infusion tube after docking.
[0027] Working principle, first, the user can directly insert the docking tube 5 into the main body 1. Since the docking tube 5 will support the inside of the main body 1 after insertion, the main body 1 will expand, and under the tightening action of the tightening ring 2, the user cannot continue to insert the docking tube 5 deeply into the main body 1. At the same time, when the docking tube 5 is inserted, it will push the first sealing ring 6, so that the first sealing ring 6 will tilt and deform in the moving direction of the docking tube 5. When the position of the first sealing ring 6 coincides with the position of the docking groove 10, it will automatically dock with the docking groove 10 under the action of the elasticity of the sealing ring 6 material. At this point, the docking process is completed. If it is necessary to continue to push the docking tube 5 into the inside of the main body 1, the user can pull the pin 3 to disengage the pin 3 from the docking ring, and then move the tightening ring 2 to re-dock the pin 3 with the next docking ring, and finally continue to push the docking tube 5 until the main body 1 is at a suitable depth.
