DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-Figure 6 The utility model provides a technical solution: a sealed medical three-way connector that is easy to connect, comprising a first connecting tube 1, a second connecting tube 2 and a first connecting block 3, the bottom of the first connecting tube 1 is connected to the second connecting tube 2, and the top outer wall of the first connecting tube 1 is provided with the first connecting block 3;

[0028] Also includes:

[0029] The first docking block 3 and the first connecting pipe 1 are an integrated structure, and a sealing ring 16 is bonded and connected to the upper surface of the first docking block 3. The first connecting pipe 1 and the second connecting pipe 2 are an integrated structure, and both left and right ends of the second connecting pipe 2 are open.

[0030] The second docking block 6 is arranged above the first docking block 3, and the first docking tube 4 is installed on the upper surface of the second docking block 6. The first docking tube 4 and the second docking block 6 are an integrated structure. A fixed card block 7 is arranged on the lower surface of the second docking block 6, and the fixed card block 7 is connected to the first docking block 3 through a fixed card slot 5, and the fixed card slot 5 is provided on the inner wall of the first docking block 3. The inner walls of the first docking block 3 and the fixed card block 7 are both provided with a limiting groove 8, and the inner part of the limiting groove 8 is connected with a fixing pin 9, and the fixed card block 7 is distributed at equal angles on the lower surface of the second docking block 6. The installation structure of the first docking tube 4 and the first connecting tube 1 is the same as the installation structure of the second docking tube 10 and the second connecting tube 2, and the inner diameters of the first docking tube 4 and the second docking tube 10 are both smaller than the inner diameter of the second connecting tube 2;

[0031] When using the sealed medical three-way connector that is easy to dock, first, the fixed block 7 on the lower surface of the second docking block 6 is engaged with the fixed slot 5 on the inner wall of the first docking block 3. Since the inner walls of the first docking block 3 and the fixed block 7 are both provided with limiting slots 8, the fixing pin 9 can be engaged with the limiting slots 8 to limit and fix the first docking block 3 and the fixed block 7, so that the first docking block 3 and the second docking block 6 can be firmly connected. The second docking block 6 is fixed to the bottom of the first docking tube 4, and the first docking block 3 is fixed to the top of the first connecting tube 1, so that the docking installation between the first connecting tube 1 and the first docking tube 4 can be realized, and the upper surface of the first docking block 3 is also bonded with a sealing ring 16, so that the sealing of the connection can be better, ensuring the sealing effect during later use;

[0032] A second butt joint pipe 10 is installed at the end of the second connecting pipe 2. A rotating rod 11 is arranged inside the second connecting pipe 2. A rotating block 12 is installed at the top of the rotating rod 11. A baffle 13 is connected to the outer wall of the rotating rod 11. The outer surface of the second connecting pipe 2 is connected to one end of an elastic spring 14. The other end of the elastic spring 14 is connected to a limit block 15. The limit block 15 is ring-shaped and made of rubber. The limit block 15 forms a telescopic structure between the elastic spring 14 and the second connecting pipe 2;

[0033] Then, the second butt joint 10 and the second connecting pipe 2 are butt-jointed and installed in the same manner. Since the inner diameter of the second butt joint 10 is the same as that of the first butt joint 4, and the inner diameter of the first butt joint 4 is smaller than that of the first connecting pipe 1, the flow rate of the transported medium can be changed, thereby improving the flexibility of the three-way joint when used. Then, the external pipe is engaged with the second butt joint 10 and the first butt joint 4.

[0034] When the three-way joint is in use, if the flow rate needs to be adjusted, the limit block 15 can be pressed to squeeze the elastic spring 14 to separate the limit block 15 and the rotating block 12, and then the rotating block 12 is rotated to make the rotating block 12 drive the rotating rod 11 to rotate together. A baffle 13 is installed on the outer wall of the rotating rod 11, so when the rotating rod 11 rotates, the baffle 13 will be rotated, which is convenient for adjusting the flow rate of the medium, and is very convenient. After the rotating block 12 rotates to a certain angle, the staff releases the pressure on the limit block 15, and under the resetting action of the elastic spring 14, the limit block 15 rises and presses against the rotating block 12 to limit the rotating block 12. The above is the working process of the entire device. The contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
