[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figure 1-4 This utility model provides a flushing infusion set with an easily openable cap, including an infusion tube 1 and a sealing cap 3. A flushing tube 4 is fixedly connected to the right end of the infusion tube 1, and the sealing cap 3 is sealed and fitted onto the outside of the flushing tube 4. A fixing tube 5 is fixedly fitted to the right side of the infusion tube 1. A pushing ring 6 is provided on the left side of the fixing tube 5, and the pushing ring 6 is slidably fitted onto the closing of the infusion tube 1. A groove 9 is provided inside the right sidewall of the fixing tube 5, and a top ring 11 is slidably connected inside the groove 9. The top ring 11 is slidably fitted onto the tube wall of the infusion tube 1. Connecting rods 12 are symmetrically fixedly installed on the right sidewall of the pushing ring 6. The right ends of the connecting rods 12 all penetrate the inside of the right sidewall of the fixing tube 5 and are slidably connected to the inside of the right sidewall of the fixing tube 5. The right end of 12 is fixedly connected to the left side wall of the top ring 11 through the inside of the fixed tube 5. The left side wall of the sealing cover 3 fits against the side wall of the top ring 11 in the initial position. The outer side wall of the fixed tube 5 is provided with a groove 10. The diameter of the pushing ring 6 is equal to the diameter of the fixed tube 5. When using the infusion tube 1, the medical staff holds the outside of the fixed tube 5 with one hand and opens the patient's conjunctival sac with the other hand. Then, the medical staff uses the hand holding the infusion tube 1 to push the pushing ring 6 with the thumb. Pushing the ring 6 moves the connecting rod 12 until the position of the top ring 11 is moved, so that the sealing cover 3 in the position of the moving top ring 11 can be directly pushed out. Then, the patient's conjunctival sac is flushed in time.

[0021] Example 2

[0022] To facilitate the repositioning of the top ring 11 and prevent obstruction of medical staff's work, squeezing allows for convenient adjustment of the liquid flow rate. In this embodiment, as shown... Figure 1-3As shown, a movable ring 7 is slidably connected inside the fixed tube 5. The two ends of the movable ring 7 are respectively fixedly sleeved on the rod wall of the connecting rod 12. Tension springs 8 are symmetrically fixed between the movable ring 7 and the inner side wall of the fixed tube 5, and the tension springs 8 are respectively sleeved on the outside of the rod wall of the connecting rod 12. A piston 2 is fixedly sleeved on the tube wall of the infusion tube 1 and is located on the left side of the push ring 6. After the sealing cover 3 is pushed out, the position of the movable ring 7 can be reset under the action of the tension spring 8, so as to conveniently reset the position of the top ring 11 and prevent obstruction of the work of medical staff.

[0023] It should be noted that in this embodiment, when using a flushing infusion set with an easily openable cap, such as Figure 1-4 As shown, when using the infusion tube 1, the medical staff should hold the outside of the fixed tube 5 with one hand and position it in the slot 10. With the other hand, open the patient's conjunctival sac. Then, the medical staff should use the hand holding the infusion tube 1 to push the push ring 6 with their thumb. Pushing the ring 6 will move the connecting rod 12 until the top ring 11 is moved. This will directly push out the sealing cap 3, which is in the position of the moving top ring 11. Then, the patient's conjunctival sac can be flushed in time. After the sealing cap 3 is pushed out, the position of the moving ring 7 can be reset under the action of the tension spring 8, so that the position of the top ring 11 can be easily reset, preventing any obstruction to the work of the medical staff.
