Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical Y-type connector. Background Technology

[0002] The Y-connector is an essential instrument for interventional procedures. Its primary functions during interventional procedures are to assist in the introduction of contrast agents and guidewires or other medical devices via balloon dilation catheters, and to control blood backflow and provide a fluid pathway into the interventional system when using guiding or dilation catheters.

[0003] In the existing technology, the Y-connector is closed by a cross-shaped incision in the silicone valve when it is in the closed state during operation, which can stop bleeding while operating other medical devices. However, relying solely on the cross-shaped incision of the silicone valve for sealing may result in an incomplete seal and cannot achieve a more stringent and secure seal. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a medical Y-type connector to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides a medical Y-type connector, including a pressing component, a first silicone valve, a sealing component, and a Y-shaped body; the pressing component, the first silicone valve, the sealing component, and the Y-shaped body are connected in sequence, the sealing component includes a rotary valve, a silicone valve cavity, and a second silicone valve, the first silicone valve is embedded in one end of the silicone valve cavity, the second silicone valve has a through hole, one end of the silicone valve cavity is detachably connected to the inner wall of the rotary valve, the rotary valve can be relatively displaced along the axial direction of one end of the Y-shaped body, the other end of the silicone valve cavity cooperates with one end of the Y-shaped body to form a compression space, and the second silicone valve is provided in the compression space.

[0007] Preferably, the pressing assembly includes a pressing handle and a spring, one end of the pressing handle is inserted into the spring, one end of the pressing handle is engaged with one end of the rotary valve, and the pressing handle can reciprocate along the axial direction of the rotary valve.

[0008] In any of the above embodiments, it is preferred that one end of the pressing handle is provided with a first hook, and the inner wall of one end of the rotary valve is provided with a first protrusion that cooperates with the first hook.

[0009] In any of the above embodiments, it is preferred that the silicone valve cavity includes a valve cavity body, one end of which is provided with an annular flange, and a second hook is provided around the periphery of the annular flange. A second boss that cooperates with the second hook is provided on the inner wall of one end of the rotary valve. A third boss is provided at one end of the Y-shaped body. The other end of the valve cavity body is inserted into one end of the Y-shaped body, and the other end of the valve cavity body cooperates with the third boss to form a compression space.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] This invention uses a pressing component to drive the opening of the first silicone valve, facilitating the rapid insertion of medical devices. After the medical device passes through the second silicone valve and the Y-shaped body in sequence, the downward movement of the rotary valve causes the silicone valve cavity and the Y-shaped body to work together to form a dynamically adjustable compression space. As the rotary valve continues to move downward, it causes the silicone valve cavity to shift, and the second silicone valve is subjected to progressive compression. Its through hole achieves an adaptive and tight fit with the outer periphery of the medical device, thereby forming a multi-seal structure, which significantly improves the sealing reliability and adaptability, and effectively prevents media leakage.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 3 As shown, a medical Y-type connector according to an embodiment of the present invention includes a pressing component, a first silicone valve 1, a sealing component, and a Y-shaped body 2. The pressing component, the first silicone valve 1, the sealing component, and the Y-shaped body 2 are connected in sequence. The sealing component includes a rotary valve 3, a silicone valve cavity, and a second silicone valve 5. The first silicone valve 1 is embedded in one end of the silicone valve cavity. The second silicone valve 5 is provided with a through hole 6. One end of the silicone valve cavity is detachably connected to the inner wall of the rotary valve 3. The rotary valve 3 can be relatively displaced along the axial direction of one end of the Y-shaped body 2. The other end of the silicone valve cavity and one end of the Y-shaped body 2 cooperate to form an adjustable compression space 7. The second silicone valve 5 is provided in the compression space 7.

[0024] The pressing component is used to open the first silicone valve 1. The first silicone valve 1 has a cross-shaped cut in its cross section. The through hole 6 of the second silicone valve 5 has a circular cross section. The first silicone valve 1 and the second silicone valve 5 are made of elastic silicone material. The Y-shaped body 2 is Y-shaped in overall shape, including a first interface end 20, a second interface end 21, and a third interface end 22. One end of the Y-shaped body 2 is the first interface end 20, and the other end is the second interface end 21. The axes of the first interface end 20 and the second interface end 21 coincide. The axis of the third interface end 22 forms an angle with the axis of the first structural end. The angle is greater than zero degrees and less than ninety degrees. As an optional embodiment, the angle can be 30 degrees or 60 degrees. Optionally, the cross sections of the first interface, the second interface, and the third interface are circular.

[0025] Furthermore, the pressing assembly includes a pressing handle 8 and a spring 9. One end of the pressing handle 8 passes through the spring 9, and one end of the pressing handle 8 engages with one end of the rotary valve 3. The pressing handle 8 can reciprocate along the axial direction of the rotary valve 3.

[0026] One end of the handle 8 is a cylindrical cavity that extends into the spring 9. One end of the cylindrical cavity engages with the rotary valve 3, while the outer surface of the other end connects to the pressing cap. When pressed, the operator moves the pressing cap downwards, causing the cylindrical cavity to contact one end of the spring 9. Pressing down compresses the spring 9 through the pressing cap.

[0027] Specifically, a first hook 10 is provided at one end of the pressing handle 8, and a first protrusion 11 that cooperates with the first hook 10 is provided on the inner wall of one end of the rotary valve 3.

[0028] One end of the press handle 8 is also one end of the cylindrical cavity. A first hook 10 is provided at one end of the cylindrical cavity. This end of the cylindrical cavity is inserted into one end of the rotary valve 3, achieving a clearance fit with the inner wall of that end. One end of the spring 9 rests against the press cap, and the other end rests against the rotary valve 3. The spring 9 is in a state of compression. Through its elastic force, the spring 9 causes the first hook 10 to contact and engage with the boss, thus limiting the pressing assembly and preventing the cylindrical cavity from detaching from the rotary valve 3. The cylindrical cavity has a first channel 23 inside, and the valve body 4 has a second channel 24 inside.

[0029] Furthermore, the silicone valve cavity includes a valve cavity body 4, one end of which is provided with an annular flange 12, and a second hook 13 is provided around the annular flange 12. A second boss 14 that cooperates with the second hook 13 is provided on the inner wall of one end of the rotary valve 3. A third boss 15 is provided at one end of the Y-shaped body 2. The other end of the valve cavity body 4 is inserted into one end of the Y-shaped body 2, and the other end of the valve cavity body 4 cooperates with the third boss 15 to form a compression space 7.

[0030] Multiple second hooks 13, preferably four, are evenly distributed around the periphery of the annular flange 12. The second hooks 13 engage with the third boss 15, limiting and fixing the silicone valve cavity, thus securing it within the inner wall of the rotary valve 3. The rotary valve 3 has a locking slot 25, into which the top portion of the second hook 13 is inserted. When the silicone valve cavity needs to be removed, simply press the second hook 13 through the locking slot 25 to disengage it from the third boss 15. Each second hook 13 corresponds to one locking slot 25. The shape of the locking slot 25 matches the cross-sectional shape of the second hook 13, which is elastic. Pushing the second hook 13 through the locking slot 25 disengages it from the second boss 14, thus disassembling the second hook 13 from the rotary valve 3. The valve cavity body 4 and the second hooks 13 can be made of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), or other plastic materials. The valve cavity body 4 can be integrally injection molded.

[0031] The outer circumferential diameter of the annular flange 12 is equal to the outer circumferential diameter of the first interface end 20 of the Y-shaped body 2. When the rotary valve 3 is rotated downward to the limit position, the bottom of the annular flange 12 contacts the end face of the first interface end 20. At this time, the bottom end of the valve cavity body 4 compresses the second silicone valve 5 to the limit state. The first silicone valve 1 is set inside the annular flange 12. The inner wall of the top of the annular flange 12 cooperates with the top of the rotary valve 3 to limit and fix the first silicone valve 1.

[0032] Optionally, a retaining ring 16 is provided on the inner wall of the other end of the valve cavity body 4, and a protrusion 17 is provided on the second silicone valve 5. The protrusion 17 is inserted into the other end of the valve cavity body 4 and cooperates with the retaining ring 16. The protrusion 17 is inserted into the inner wall of the silicone valve body to limit and fix the second silicone valve 5. The retaining ring 16 contacts the protrusion 17 and together with the inner wall of the valve cavity body 4, it limits the second silicone valve 5.

[0033] The blocking ring 16 has a ring-shaped structure. The through hole 6 on the second silicone valve 5 passes through the protrusion 17 and the bottom of the second silicone valve 5. The diameter of the through hole 6 is equal to the diameter of the inner ring of the blocking ring 16.

[0034] Furthermore, the rotary valve 3 is threadedly engaged with one end of the Y-shaped body 2. The outer wall of the first interface end 20 of the Y-shaped body 2 is provided with an external thread, and the inner wall of the rotary valve 3 is provided with an internal thread that engages with the external thread. By rotating the rotary valve 3, the rotary valve 3 moves along the axial direction of the first interface end 20 of the Y-shaped body 2.

[0035] Furthermore, it also includes an inner conical locking connector 18, which is connected to the other end of the Y-shaped body 2. A sealing ring 19 is provided at the connection between the inner conical locking connector 18 and the Y-shaped body 2. The inner conical locking connector 18 is used to connect the Y-shaped body 2 to other pipelines.

[0036] The working principle of this utility model embodiment is as follows: Press the pressing component to make the pressing component penetrate the cross-shaped cut of the first silicone valve, place the medical device into the first channel and the second channel, pass through the second silicone valve and exit from the second interface end of the Y-shaped body, and then turn the rotary valve to make the valve body squeeze the second silicone valve. The second silicone valve is compressed, the through hole becomes smaller and comes into close contact with the outer circumferential surface of the medical device to achieve a seal.

[0037] The first and second silicone valves of this invention constitute a dual sealing structure. The two valves work together to form a multi-level sealing barrier, which significantly enhances the sealing reliability. The first silicone valve achieves initial sealing and isolation, while the second silicone valve forms an adaptive and tight fit with the outer surface of the medical device under pressure. The two valves work together to effectively compensate for the shortcomings of a single sealing structure, which not only greatly improves the overall sealing performance, but also adapts to the sealing requirements of different specifications of medical devices, effectively prevents media leakage, and ensures the safety and stability of the operation process.
