[0005] The socket assembly includes a connecting sleeve, a conical hemostatic valve, an accordion-type hemostatic valve and a button. One end of the connecting sleeve has an internal thread, and one end of the main pipe has an external thread. The internal thread of the connecting sleeve is connected with the external thread of the main pipe.

[0006] The connecting sleeve has a guide tube extending toward the main pipe, the conical hemostatic valve is connected to an end of the guide tube close to the main pipe, and the accordion-type hemostatic valve is connected to an end of the guide tube away from the main pipe;

[0046] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] See also Figures 1 to 6 As shown, the present application provides a Y-type connector, including a valve body 10, a movable joint 20 and a socket assembly 30. The valve body 10, the movable joint 20 and the socket assembly 30 are pre-assembled together, wherein:

[0049] The valve body 10 has a main pipe 11 and a branch pipe 12 connected to the main pipe 11. The movable joint 20 and the socket assembly 30 are respectively connected to the opposite ends of the main pipe 11. The end of the main pipe 11 connected to the socket assembly 30 has an external thread 111.

[0050] The socket assembly 30 includes a connecting sleeve 31 , a conical hemostatic valve 32 , an accordion hemostatic valve 33 and a button 34 . One end of the connecting sleeve 31 has an internal thread 313 , and the internal thread 313 of the connecting sleeve 31 is matched with the external thread 111 of the main pipe 11 .

[0051] The connecting sleeve 31 has a guide tube 314 extending toward the main tube 11 . The conical hemostatic valve 32 is connected to one end of the guide tube 314 close to the main tube 11 . The accordion-type hemostatic valve 33 is connected to one end of the guide tube 314 away from the main tube 11 .

[0052] The conical hemostatic valve 32 has a tapered head on the end near the main pipe 11. The head is made of elastic silicone and has a socket that connects the main pipe 11 to the guide pipe 314. The inner wall of the main pipe 11 near the head has a guide tapered surface, and the outer wall of the head fits in contact with the guide tapered surface.

[0053] The accordion-style hemostatic valve 33 includes a valve disc made of elastic silicone material. One end of the valve disc has a protrusion 331, which is embedded in the guide tube 314. The outer annular wall 343 of the protrusion 331 abuts the inner wall of the guide tube 314. The end surface of the protrusion 331 has a cross-shaped cutout 332, which divides the protrusion 331 into four valve discs 333.

[0054] One end of the button 34 has an insertion tube 341, which passes through the button 34 and is connected to the instrument socket 342 on the button 34. The insertion tube 341 is inserted into the connecting sleeve 31 from the other end of the connecting sleeve 31, and the tube opening of the insertion tube 341 is aligned with the center of the cross cut 332.

[0055] One end of the button 34 has an annular wall 343, which surrounds the outside of the insertion tube 341. The outer wall of the annular wall 343 has a retaining groove 344. The inner wall of the connecting sleeve 31, near the button 34, has protruding retaining teeth 315 that engage with the retaining groove 344. The outer wall of the annular wall 343 has a locking groove 345 that extends circumferentially around the annular wall 343 and connects laterally with the retaining groove 344. To facilitate manufacturing and installation of components such as the accordion-style hemostatic valve 33 within the connecting sleeve 31, the connecting sleeve 31 is welded together from a front half 311 and a rear half 312. The internal threads 313 and guide tube 314 are located on the front half 311, while the retaining teeth 315 are located on the rear half 312.

[0056] The Y-connector operates as follows: To quickly insert an interventional instrument, the button 34 is pressed. The insertion tube 341 on the button 34 presses against the cross-cut 332 on the valve disc and passes through the cross-cut 332, allowing the insertion tube 341 to enter the guide tube 314 and connect with the socket on the cone head. The interventional instrument is placed into the insertion tube 341 through the instrument socket 342 on the button 34, then passes along the insertion tube 341 into the guide tube 314, and then passes through the socket on the cone head into the valve body 10. Then, the button 34 is released, and the valve disc 333 on the valve disc is reset. Simultaneously, the elastic force of the valve disc 333 retracts the insertion tube 341, and the valve disc 333 on the valve disc tightly adheres to and clamps the outside of the interventional instrument, sealing the guide tube 314. Then rotate the connecting sleeve 31 to make the main pipe 11 on the valve body 10 penetrate into the connecting sleeve 31 , driving the cone head to squeeze the guide cone surface. The cone head will be deformed by the action of the guide cone surface, thereby clamping the interventional instrument and sealing the main pipe 11 .

[0057] In addition, after pressing the button 34, the button 34 can be rotated to rotate the limiting teeth 315 on the connecting sleeve 31 into the locking groove 345, thereby fixing the button 34 and preventing it from retreating due to the elastic force after releasing the button 34. This eliminates the need to constantly press the button 34 with your fingers. After inserting the interventional instrument, the button 34 can be rotated in the opposite direction and released to seal and lock the interventional instrument.

[0058] The dual hemostatic valve design allows the Y-connector to simultaneously utilize both rotary and push-action functions. Rotation provides a more secure seal, a tight seal, and flexible valves. The push-action design, on the other hand, allows for single-handed operation, quickly stopping bleeding. The multi-flap design allows for easy gripping of connected instruments and rapid hemostasis. Pressing the valve easily opens the valve, while withdrawing allows for easy removal of the instrument and instantly seals it, resolving the conflict between unobstructed access and a poor seal.
