Technical Field

[0001] This utility model relates to the field of medical connector technology, specifically to a sterile coupling medical connector structure. Background Technology

[0002] In the medical field, ensuring safe and sterile connections between medical devices and accessories is crucial. Coupling connectors are widely used for fluid exchange between different types of medical devices, such as the connection between infusion pumps and infusion bags, and the docking of dialysis machines with patient vascular access. These connectors not only ensure smooth fluid flow but also facilitate quick and accurate operation by medical staff, reducing preparation time and improving work efficiency.

[0003] Although current coupling connectors on the market can meet basic functional requirements, there is still room for improvement in some details. For example, existing coupling connector designs are not good at sealing and are prone to leakage after repeated insertion and removal. This not only affects the treatment effect but may also bring additional infection risks to patients. At the same time, some connectors require a lot of force to achieve a complete seal during installation, which causes some inconvenience to medical staff and increases the possibility of misoperation. Utility Model Content

[0004] The purpose of this invention is to provide a sterile coupling medical connector structure to solve the problems mentioned in the background art, such as insufficient sealing performance of current coupling connectors on the market, easy leakage after repeated insertion and removal, and the need to apply large pressure during installation to achieve a complete seal, which causes inconvenience to medical staff and increases the risk of misoperation.

[0006] Preferably, the connection between the inner and outer sealing rings is surrounded by several sets of corresponding buffer cavities, and the elastic support pieces are all embedded in the buffer cavities at the connection between the inner and outer sealing rings.

[0007] Preferably, the support block is uniformly welded and fixed to the inner wall of the fixed sleeve edge, and the extrusion member is connected to the inner wall of the support block through an elastic pad.

[0008] Preferably, a plurality of elastic clips are evenly arranged around the outer wall of the connecting end of the fixed ring, and a plurality of slots that cooperate with the elastic clip structure are arranged around the connecting ring.

[0010] Preferably, the support block and the extrusion member are both arc-shaped structures, and the support block and the extrusion member are provided in four sets on the inner wall of the fixed sleeve ring.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: the aseptic coupling medical connector structure improves sealing performance and reliability, simplifies the installation process, reduces operational difficulty, and effectively reduces the risk of leakage and the possibility of misoperation.

[0014] 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.

[0015] Please see Figure 1-4This utility model provides a technical solution: a sterile coupling medical connector structure, including a connector body 1, a connector head 2 fixed at the upper end of the connector body 1, the connector head 2 and the connector body 1 being an integral structure, a connecting ring 3 being provided on the outside of the connection between the connector body 1 and the connector head 2, a retaining ring 4 being engaged on the connecting ring 3, and a double-layer sealing mechanism consisting of an inner sealing ring 5, an outer sealing ring 6 and an elastic support 7 being provided inside the retaining ring 4, the inner sealing ring 5 being made of nitrile rubber, having good mechanical strength, the outer sealing ring 6 being made of fluororubber, having excellent high temperature resistance and weather resistance, the elastic support 7 being evenly distributed between the inner sealing ring 5 and the outer sealing ring 6, and several sets of support blocks 8 and extrusion parts 9 being provided on the inner wall of the retaining ring 4 along its edge. The reinforcement assembly provides additional pressure when the device port is inserted. In this structure, when the medical device port is inserted into the connector 2 and mates with the connector body 1, the retaining ring 4 is pre-installed on the outside of the connector 2 via a connecting ring 3. As the medical device port is further inserted, the inner sealing ring 5 and the outer sealing ring 6 deform under the force of the elastic support 7, filling any possible tiny gaps and tightly fitting the outer wall of the medical device port, thus achieving a more rigorous seal. Simultaneously, the reinforcement assembly consisting of the support block 8 and the extrusion member 9 provides additional pressure during device port insertion, further ensuring stability and sealing. Overall, this design not only improves the safety and stability of the connection but also... This significantly reduces the risk of leakage caused by repeated insertion and removal. Furthermore, since the entire assembly process does not require excessive force, it greatly reduces the operational burden on medical staff, decreases the possibility of misoperation, and thus improves the overall treatment effect and patient safety. It effectively solves the problems of insufficient sealing performance and complex operation existing in current technologies, providing a more reliable option for medical environments. Several corresponding buffer cavities are arranged around the connection between the inner sealing ring 5 and the outer sealing ring 6, and the elastic support plates 7 are all embedded in the buffer cavities at the connection between the inner sealing ring 5 and the outer sealing ring 6. This structure not only provides additional space to accommodate equipment ports of different sizes, but also allows the elastic support plates 7 to move flexibly and shape within them. This design allows the inner sealing ring 5 and outer sealing ring 6 to automatically adjust their sealing force according to pressure changes, thus forming a more tight and reliable double-layer sealing structure. The support block 8 is uniformly welded and fixed to the inner wall of the fixed ring 4. The extrusion component 9 is connected to the inner wall of the support block 8 through an elastic pad. When the medical device port is inserted, the extrusion component 9 first contacts the outer wall of the port and begins to compress the elastic pad. This allows the extrusion component 9 to adapt to ports of different diameters, ensuring a tight fit while avoiding damage caused by excessive compression, further improving the overall sealing performance. At the same time, the elastic pad between the extrusion component 9 and the support block 8 can be made of medical-grade silicone or fluororubber, which have excellent biocompatibility, chemical corrosion resistance, and temperature stability.The retaining ring 4 maintains its physical properties under various medical conditions. Several elastic clips 10 are evenly arranged around the outer wall of the connecting end, and several slots that mate with the elastic clips 10 are arranged around the connecting ring 3. During assembly, the retaining ring 4 only needs to be gently pushed into the connecting ring 3, and the elastic clips 10 will automatically find and embed themselves in the corresponding slots, achieving a quick and reliable connection. This mechanism not only simplifies the installation process and reduces operational difficulty, but also prevents accidental loosening due to external tension or vibration through a tight mechanical lock, further enhancing the safety and stability of the overall structure. The elastic clips 10 have a V-shaped structure and are fixedly connected to the outer wall of the retaining ring 4 via connecting posts 11. The connecting posts 11 and the elastic clips... The connection point of component 10 is an elastic structure. The V-shaped design of this elastic clip 10 allows it to deform elastically under pressure, smoothly entering the slot on the connecting ring 3. After passing through the slot, it returns to its original shape, forming a secure lock. Furthermore, the elastic characteristics of the outer end of the connecting post 11 allow the elastic clip 10 to be finely adjusted as needed, ensuring a smooth and accurate insertion into the slot. Both the support block 8 and the pressing component 9 are arc-shaped structures, and four sets of support blocks 8 and pressing components 9 are provided on the inner wall along the edge of the fixed ring 4. This structure allows the support blocks 8 and pressing components 9 to better conform to the outer wall of the equipment port, providing uniform pressure distribution and ensuring 360-degree all-around stable support and sealing effect, resulting in a larger contact area and further improving the stability and sealing of the connection.

[0016] Working principle: When using this sterile coupling medical connector structure, the retaining ring 4 is first pre-assembled with the connecting ring 3 via the elastic locking member 10 on it. That is, the elastic locking member 10 automatically finds and embeds into the corresponding slot on the connecting ring 3, realizing a quick and reliable locking between the retaining ring 4 and the connecting ring 3. After the retaining ring 4 is installed on the outside of the connector 2, the medical device port is inserted into the connector 2. It will first come into contact with the compression member 9. The compression member 9 begins to compress the elastic pad with the cooperation of the support block 8, and gradually adjusts its position to adapt to the shape of the outer wall of the port as the device port is further inserted. At the same time, the elastic support piece 7 between the inner sealing ring 5 and the outer sealing ring 6 deforms under the pressure of the device port, tightly fitting the outer wall of the medical device port. As the device port continues to go deeper, the four sets of reinforcement components evenly distributed on the support block 8 also continue to play a role, providing additional pressure support to ensure the stability and sealing of the entire connection process. In this way, the safe docking of the medical device port and the connector body 1 is completed, thus completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
