Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical connection valves, and particularly relates to a medical Y-shaped connection valve. Background Technique
[0002] Medical Y-valves are commonly used in vascular interventional therapy. During the operation, a pipeline into the human body is first established by using instruments, and the Y-shaped connection valve is installed when the catheter or guide wire enters the human body. Its main function is to prevent blood from leaking out from the gap between the introducer and the guiding catheter through the sealing mechanism at the proximal end of the valve body. This patent specifically relates to a segmented pressing type medical Y-valve. The existing Y-shaped connection valves are mainly divided into two categories according to the opening and closing methods of the sealing ring, namely, the pressing type and the rotating type. When the guide wire or catheter passes through the Y-valve, the sealing ring is in an open state for easy installation. After the installation is completed, the sealing ring is completely attached to the outer surface of the guide wire or catheter by pressing or tightening to seal and prevent blood from leaking out. The pressing type realizes the sealing fit with the introducing component through the compression deformation of the sealing ring, can be operated with one hand, generally has a small adhesion force, and the maximum injection pressure that can be withstood during injection is not high.
[0003] Due to the need to ensure the passability during the penetration process of the existing medical Y-valve, the initial state of the sealing ring cannot be completely attached and sealed to the surface of the introducer, and blood leakage is likely to occur. For the commonly used pressing type Y-valve, its fastening after pressing is mainly achieved by pressing the sealing ring cover, so that the sealing ring cover generates plastic elastic deformation during the pressing process, increasing the friction force between the sealing ring cover and the Y-valve body to achieve the fastening after compression. During the actual operation, the sealing ring cover may be accidentally touched and moved, which may lead to sealing failure and there is a certain risk. At the same time, when the introducing component penetrates, it usually enters from the sealing end of the Y-valve, extends to the connection between the Luer connector and the guiding catheter, and then enters the human body. Since the Y-valve is welded by multiple plastic parts, in order to prevent the connecting position from hindering the introducing component, the connecting and transitional positions are usually designed to be in a shape that is easy to pass through. However, due to the common installation method being one-way, the transitional design is also only one-way. If the introducing component needs to pass through in the reverse direction, it will be difficult to operate. Therefore, we propose a medical Y-shaped connection valve. Content of the Utility Model
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a medical Y-shaped connection valve, which effectively solves the above problems.

Detailed implementation manner
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-4, a medical Y-shaped connection valve, comprising a Y-valve body 400. A sealing ring 300 is fixedly connected to the upper side of the Y-valve body 400, and a sealing ring cover 100 is fixedly connected to the upper side of the Y-valve body 400. A segmented buckle 700 is fixedly connected to the left side of the Y-valve body 400. A two-way pass-through structure 800 is fixedly connected to the lower side of the Y-valve body 400. An external conical Luer connector 600 equipped with a threaded retaining ring is fixedly connected to the lower side of the two-way pass-through structure 800. By setting two sets of locking blocks 110 to cooperate with the segmented buckle 700, the sealing ring 300 can be gradually released, making the operation of this device more flexible and easier to adjust when penetrating the guiding member. After the segmented buckle 700 is unlocked, the spring 200 automatically rebounds the sealing ring cover 100, making the single-handed operation more convenient. The connection position of the two-way pass-through structure 800 is designed as a two-way transition, which can support the guiding member to penetrate the Y-valve from different directions. Two sets of locking blocks 110 are fixedly connected to the left side of the sealing ring cover 100, and the lower sides of the locking blocks 110 are inclined. By setting the locking blocks 110, the limiting stability of the Y-valve body 400 to the segmented buckle 700 is improved. A convex block 410 is fixedly connected to the left side of the Y-valve body 400, and the convex block 410 is located at the lower right side of the segmented buckle 700. By setting the convex block 410 to limit the lower side of the segmented buckle 700, the segmented buckle 700 is more stable during use, and the segmented buckle 700 can more effectively limit the sealing ring cover 100. A spring 200 is fixedly connected to the upper side of the sealing ring 300, and the upper side of the spring 200 is fixedly connected to the sealing ring cover 100. By setting the spring 200, the sealing ring cover 100 can return to its original position automatically after use, improving the stability of the use of this device. An auxiliary plate 420 is fixedly connected to the right side of the Y-valve body 400, and the right side of the auxiliary plate 420 is connected to a side-mounted internal conical Luer connector 500. By setting the auxiliary plate 420, the stability of the side-mounted internal conical Luer connector 500 during use is improved, avoiding shaking during the use of the side-mounted internal conical Luer connector 500, and at the same time facilitating the user to take it. Function blocks 310 are fixedly connected to both the left and right sides of the sealing ring 300, and sliding grooves matching the function blocks 310 are provided on both the left and right sides of the sealing ring cover 100. By setting the cooperation between the function blocks 310 and the sliding grooves, when the sealing ring cover 100 squeezes the sealing ring 300, the sealing ring 300 will not have large shaking and displacement phenomena, improving the stability of the use of this device.
[0023] Working principle: When the new solution is implemented, in the initial state, the sealing ring cover 100 is pressed tightly. The downward movement of the sealing ring cover 100 drives the downward movement of the clamping block 110. When the clamping block 110 moves downward, it squeezes the upper side of the segmented buckle 700, causing the upper side of the segmented buckle 700 to move away from the Y-valve body 400. Then, when the lower side of the segmented buckle 700 touches the convex block 410 and can no longer move, at this time, the sealing ring cover 100 is locked by the upper side of the segmented buckle 700, and the inner tube of the sealing ring cover 100 fully expands the sealing ring 300, enabling the introduction component to pass through the Y-valve smoothly. After the installation is completed, the segmented buckle 700 is released, and the spring 200 pushes the sealing ring cover 100 to the farthest position, and the sealing ring 300 fits on the surface of the installed introduction component.
