Description

Technical Field

[0001] This invention relates to the field of medical tubing connection structure technology, specifically a connection component between an abdominal wall feeding tube and an enteral feeding bag. Background Technology

[0002] Currently, abdominal wall feeding tubes and enteral feeding bags are widely used in clinical practice for long-term or short-term enteral nutritional support. Their core component is the connecting assembly between the feeding tube and the feeding bag. This assembly not only needs to ensure smooth delivery of the nutrient solution but also must possess good sealing properties and ease of operation to meet the demands of high-frequency use in a medical environment.

[0003] Existing connection components generally employ mechanical snap-fit ​​or socket-type structures. A typical solution involves a female and male connector directly plugging together to form a passage, with a simple sealing ring or valve structure inside to achieve fluid blockage. While this traditional design can accomplish basic infusion functions in practical applications, it still has the following shortcomings:

[0004] Traditional connection components often consist of multiple stacked parts at the joint, with numerous connection surfaces, sealing grooves, and cavities, making them prone to nutrient solution residue and creating areas where dirt and grime can accumulate. Incomplete cleaning and disinfection can lead to bacterial growth and cross-infection, failing to meet the high hygiene and safety requirements of clinical practice.

[0005] Existing connector structures mostly rely on manual pushing and twisting to complete the connection. When connecting or disconnecting the fluid circuit, valves or seals require additional operation to open or close, increasing the burden on medical staff. In some emergency operation scenarios, the cumbersome operation procedures may cause leakage of nutrient solution or delay the infusion time, which is not conducive to the efficiency of clinical application. Moreover, if accidentally dislodged, they cannot seal themselves, leading to fluid leakage and bacterial contamination.

[0006] Existing sealing structures primarily rely on tight fit or ring friction to maintain sealing and positioning. With increased use, these joints are prone to wear and aging, leading to a decline in sealing effectiveness. Furthermore, the lack of an auxiliary positioning mechanism allows for slight loosening of the joint during use, increasing the risk of liquid leakage.

[0007] In summary, existing connection components for abdominal wall feeding tubes and enteral feeding bags generally suffer from problems such as complex structure, difficulty in cleaning, lack of quick-connect self-sealing function, and unreliable sealing positioning. There is an urgent need for an improved connection component with a simple structure, quick connection capability, and self-sealing and magnetic positioning functions to enhance the safety and convenience of use. Summary of the Invention

[0008] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0009] Therefore, the technical solution adopted by the present invention is as follows: a connection assembly between an abdominal wall feeding tube and an enteral feeding bag, including a female connector, a male connector, and a sealing assembly. The ends of the female connector and the male connector are respectively provided with connecting rods, and both are provided with flow channel holes inside, which can form a liquid channel in the connected state. The female collar and the male collar are positioned by mutual cooperation through the collar surface to ensure the stability of the connection. The sealing assembly includes a sliding collar, a valve block, a reset ring, and a reset spring. The valve block automatically closes the flow channel in the unconnected state and is pushed open by the connecting rod during the connection process, thereby realizing the automatic flow and disconnection of the liquid.

[0010] In a preferred embodiment, the female connector includes a first connecting rod, and the male connector includes a second connecting rod. Both are of the same size and are semi-cylindrical in shape. When the female connector and the male connector are engaged, the flow channels of the first and second connecting rods are interconnected. Specifically, this structure ensures accurate flow of the liquid path and smooth fluid transport.

[0011] In a preferred embodiment, the first and second connecting rods are each provided with a first sealing magnetic ring, with their magnetic poles arranged opposite each other; a second sealing magnetic ring is provided on the valve block surface, with its magnetic poles opposite to those of the first sealing magnetic ring. Specifically, magnetic attraction is used to achieve engagement positioning and valve block sliding guidance, improving the sealing performance and stability during the fluid circuit engagement process.

[0012] In a preferred embodiment, the first and second sealing magnetic rings are configured to be the same size and are both annular sealing ring structures made of magnetic rubber. Specifically, this design combines flexible sealing with magnetic positioning, ensuring no liquid leakage while achieving stable adsorption and positioning of the valve block.

[0013] In a preferred embodiment, the inner sides of both the female and male collars are provided with limiting grooves, the inner side of the valve block is provided with a limiting structure, and the surface of the collar has a raised edge located inside the limiting groove. Specifically, through the cooperation of the limiting groove and the raised edge, the collar and valve block are guided to slide stably in a straight direction, avoiding deviation and improving the guiding accuracy of the docking process.

[0014] In a preferred embodiment, the valve block is further configured as follows: the two ends of the return spring abut against the surface of the connecting rod and the inner side of the sliding sleeve ring, respectively. Specifically, when the connector is disengaged, the return spring automatically pushes the valve block into a closed state; when the connector is engaged, the connecting rod pushes the valve block to overcome the elastic force and open the liquid circuit, thereby achieving automatic liquid flow.

[0015] In a preferred embodiment, the reset ring is further configured such that it includes a ring plate and several integrally formed elastic top plates. Specifically, the elastic top plates are made of elastic metal sheets, which can provide elastic support and positioning during the reset process of the sliding ring, thereby enhancing the reset effect and the service life of the joint.

[0016] In a preferred embodiment, both the mating surface of the female collar and the outer surface of the male collar are machined to have a roughened texture. Specifically, the roughened texture generates friction during mating, ensuring a tight fit between the female and male collars, further improving the sealing performance and anti-loosening properties of the joint.

[0017] In a preferred embodiment, the female connector, male connector, first connecting rod, female collar, second connecting rod, and male collar are all made of medical-grade rubber. Specifically, this material has good biocompatibility, corrosion resistance, and flexible sealing properties, ensuring the long-term safe use of the product in medical environments.

[0018] In summary, the connection assembly between the abdominal wall feeding tube and the enteral feeding bag of the present invention avoids the accumulation of dirt and grime through a simplified structural design, improves operational convenience through a quick-connect and self-sealing integrated structure, and enhances the sealing reliability and positioning accuracy of the fluid circuit through a magnetic sealing structure, thereby improving the overall safety, stability and operational efficiency during clinical use.

[0019] The beneficial effects achieved by this invention are as follows:

[0020] 1. This invention adopts a compact structural design of female connector, male connector, and sealing component. The internal channel is rationally configured with valve block, sliding sleeve ring, and reset ring, avoiding the problems of liquid residue and dirt accumulation caused by the complexity of parts and excessive seams in traditional connectors. The overall structure has a smooth surface and simplified joint interface, significantly improving cleanliness and disinfection convenience, and meeting the hygiene and safety requirements of medical environments.

[0021] 2. This invention achieves rapid alignment and stable connection through the interlocking of the female and male collars, and the guiding effect of the anti-foolproof protrusion and positioning groove on the sliding collar. During the engagement process, the first and second connecting rods push the valve block to automatically open the fluid passage; upon separation, the valve block automatically closes the fluid passage under the action of the return spring, forming an integrated function of quick connection and self-sealing. This structure achieves the opening and closing of the fluid passage without additional operation, significantly improving the efficiency of clinical operations.

[0022] 3. This invention incorporates a first sealing magnetic ring and a second sealing magnetic ring between the first connecting rod, the second connecting rod, and the valve block. Magnetic attraction is used to achieve positioning and sealing during the connection and closure of the liquid circuit. The magnetic attraction not only ensures the stability of the valve block during sliding but also enhances the sealing reliability after engagement, preventing liquid leakage and improving the overall safety and reliability of the device during use. In the event of accidental disconnection, it can automatically seal itself, preventing external contamination from entering. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0038] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0039] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a connection assembly between an abdominal wall feeding tube and an enteral feeding bag.

[0040] Combination Figures 1-10 As shown, the present invention provides a connection assembly between an abdominal wall feeding tube and an enteral feeding bag, including a female connector 100, a male connector 200, and a sealing assembly 300.

[0041] The female connector 100 has a first connecting rod 110 at its end, and the male connector 200 has a second connecting rod 210 at its end. Both the first connecting rod 110 and the second connecting rod 210 have flow channel holes 211 inside, for communicating with the internal flow channels of the female connector 100 and the male connector 200. A sealing flange 222 is provided on the outer periphery of the port of the flow channel hole 211. A female collar 120 and a male collar 220 are respectively fixedly connected to the ends of the female connector 100 and the male connector 200, for positioning the sliding of the sealing assembly 300. The inner side of the female collar 120 has a fitting surface 121 that matches the outer surface of the male collar 220, achieving a stable fitting between the two.

[0042] The sealing assembly 300 includes a sliding ring 310, a valve block 320, and a return ring 330 and a return spring 340 located at one end of the sliding ring 310 and the valve block 320, respectively. One side of the valve block 320 slides against the surfaces of the first connecting rod 110 and the second connecting rod 210, and the valve block 320 is sleeved on the inner side of the sliding ring 310. The two sliding rings 310 are respectively slidably sleeved on the inner sides of the female ring 120 and the male ring 220. The surface of the valve block 320 has an annular groove 321, and a second sealing magnetic ring 322 is embedded in its inner side. It magnetically attracts and cooperates with the first sealing magnetic ring 212 on the surfaces of the first connecting rod 110 and the second connecting rod 210 to provide a sealing and positioning function in the closed and open states.

[0043] In a preferred embodiment, the female connector 100, the first connecting rod 110, the male connector 200, and the second connecting rod 210 are of the same size, and both the first connecting rod 110 and the second connecting rod 210 are semi-cylindrical structures. When the female connector 100 and the male connector 200 are mated, the surface flow channel holes 211 of the first connecting rod 110 and the second connecting rod 210 can be accurately aligned and connected to each other, realizing the connection of the liquid path.

[0044] In another embodiment, both the first connecting rod 110 and the second connecting rod 210 are provided with a first sealing magnetic ring 212, with their magnetic poles arranged opposite each other. When the female connector 100 and the male connector 200 are engaged, the two first sealing magnetic rings 212 are engaged and positioned by magnetic attraction. At the same time, the magnetic poles of the first sealing magnetic ring 212 and the second sealing magnetic ring 322 on the surface of the valve block 320 are arranged opposite each other, so that the valve block 320 can obtain magnetic guidance and positioning when sliding on the surfaces of the first connecting rod 110 and the second connecting rod 210, thereby further improving the sealing performance and stability of the hydraulic circuit connection.

[0045] In another embodiment, both the first sealing magnetic ring 212 and the second sealing magnetic ring 322 are annular sealing ring structures of the same specifications and are made of magnetic rubber. This magnetic structure has both a flexible sealing function and a magnetic positioning effect, thereby ensuring the reliable opening and closing of the valve block 320 during the liquid circuit docking process.

[0046] In a preferred embodiment, both the female collar 120 and the male collar 220 have limiting grooves on their inner sides to guide the sliding of the sliding collar 310. The valve block 320 has a limiting structure on its inner side, and the surface of the sliding collar 310 has a raised edge located within the limiting groove, ensuring that the sliding collar 310 maintains linear sliding during the mating of the female connector 100 and the male connector 200. One side of the sliding collar 310 is elastically supported by a reset ring 330, achieving an automatic reset function.

[0047] In another embodiment, the valve block 320 is semi-cylindrical, and the return spring 340 slides against the surfaces of the first connecting rod 110, the second connecting rod 210, and the inner side of the sliding sleeve ring 310. The valve block 320 remains closed under the action of the return spring 340. When the female connector 100 and the male connector 200 are engaged, the valve block 320 can overcome the elastic force and slide back under the push of the connecting rod, thereby opening the hydraulic circuit.

[0048] In another embodiment, the reset ring 330 includes a ring plate 331 and a plurality of elastic top plates 332 located on the surface of the ring plate 331. The ring plate 331 and the elastic top plates 332 are integrally formed structures, and the elastic top plates 332 are made of elastic metal sheets, which can provide elastic support and positioning during the reset process of the sliding ring 310.

[0049] In a preferred embodiment, the inner surface of the mating surface 121 of the female collar 120 and the outer surface of the male collar 220 are both machined with a rough surface structure. When the female connector 100 and the male connector 200 are engaged, the outer periphery of the male collar 220 fits tightly with the inner surface of the mating surface 121, further enhancing the friction and sealing of the engagement structure and preventing loosening.

[0050] In another embodiment, the female connector 100, the male connector 200, and the first connecting rod 110, female collar 120, second connecting rod 210, and male collar 220 on their surfaces are all made of medical-grade rubber. This material has good biocompatibility and sealing performance, meeting the safety requirements for medical use.

[0051] Working principle and usage process of this invention:

[0052] The connection assembly between the abdominal wall feeding tube and the enteral feeding bag of the present invention establishes a nutrient solution passage through the docking of a female connector 100 and a male connector 200. One end of the female connector 100 is provided with a first connecting rod 110, and one end of the male connector 200 is provided with a second connecting rod 210. When docked, the two are connected through a flow channel hole 211, allowing the liquid to flow smoothly. The female collar 120 and the male collar 220 are interlocked and tightly fitted for positioning, ensuring the stability and sealing of the connection.

[0053] Inside the sealing assembly 300, a sliding sleeve ring 310 is fitted inside the female sleeve ring 120 and the male sleeve ring 220. The valve block 320 is slidably installed inside the sliding sleeve ring 310, and one side is elastically supported by a return spring 340. The end of the sliding sleeve ring 310 is reset and positioned by a return ring 330. When the female connector 100 and the male connector 200 are not engaged, the second sealing magnetic ring 322 on the surface of the valve block 320, under the action of the return spring 340, achieves a seal by contacting the first sealing magnetic ring 212 on the surfaces of the first connecting rod 110 and the second connecting rod 210, automatically placing it in a closed position, blocking the flow of liquid, and preventing the leakage of liquid from the abdominal wall feeding tube and the enteral feeding bag.

[0054] When the female connector 100 and the male connector 200 are engaged, the first connecting rod 110 and the second connecting rod 210 slide alternately and push the valve block 320 to slide, thus opening the flow channel hole 211 and allowing the nutrient solution to flow smoothly. During this process, the first sealing magnetic ring 212 and the second sealing magnetic ring 322 attract and position each other, which not only provides a sealing function but also ensures the sliding positioning effect of the valve block 320, preventing liquid leakage.

[0055] Usage process

[0056] In a preferred embodiment of the present invention, during the docking process, the female connector 100 and the male connector 200 achieve fluid passage connection through the following steps in sequence:

[0057] Initial state: When the female connector 100 and male connector 200 are separated, the two sliding rings 310 are respectively fitted inside the female ring 120 and the male ring 220. The sliding rings 310 and valve block 320 are kept in an extended state under the elastic action of the reset ring 330 and the reset spring 340. At this time, the valve block 320 is in the closed position under the support of the reset spring 340, that is, the second sealing magnetic ring 322 on the surface is in contact with the first sealing magnetic ring 212 on the surface of the first connecting rod 110 and the second connecting rod 210. No fluid channel is established between the first connecting rod 110 and the second connecting rod 210, ensuring that the nutrient solution does not leak.

[0058] Sliding ring alignment: As the female connector 100 and male connector 200 begin to approach each other, the front ends of the two sliding rings 310 first contact each other, and the anti-fooling protrusion 311 on the surface of the sliding ring 310 on the female connector 100 side and the positioning groove 312 on the surface of the sliding ring 310 on the male connector 200 side gradually align. Through the mutual cooperation of the anti-fooling protrusion 311 and the positioning groove 312, the directional consistency of the two sliding rings 310 during the engagement process is ensured, avoiding misalignment. Simultaneously with engagement, the female ring 120 is fitted onto the outer circumference of the male ring 220;

[0059] Synchronous retraction: As the female connector 100 and male connector 200 continue to approach each other, the front ends of the two sliding rings 310 abut against each other and retract synchronously, and under the action of contact pressure, they retract simultaneously inward. Due to the constraint of the limiting groove, the two sliding rings 310 maintain stable linear sliding, realizing synchronous retraction.

[0060] Valve block opening process: As the sliding sleeve ring 310 retracts, the front end of the first connecting rod 110 at the female connector 100 gradually contacts the surface of the valve block 320 on the male connector 200, pushing it to slide inward against the elastic force of the return spring 340; simultaneously, the front end of the second connecting rod 210 at the male connector 200 also gradually contacts the surface of the valve block 320 on the female connector 100, and synchronously pushes it to slide inward. In this way, under the combined action of the first connecting rod 110 and the second connecting rod 210, the two valve blocks 320 retract synchronously along the inner wall direction of the sliding sleeve ring 310, causing the annular groove 321 on the valve block 320 to gradually disengage from the closed position from the sealing magnetic ring 322.

[0061] Flow channel connection: As the valve block 320 retracts completely, the front ends of the first connecting rod 110 and the second connecting rod 210 gradually approach and finally fit together, so that the flow channel holes 211 on their surfaces are accurately aligned and connected. At this time, a complete liquid flow channel is formed between the female connector 100 and the male connector 200, and the nutrient solution can flow smoothly from the female connector 100 end to the male connector 200 end, realizing the liquid delivery between the abdominal wall feeding tube and the enteral feeding bag.

[0062] Stable sealing and positioning: When the flow channel is connected, the first sealing magnetic ring 212 and the second sealing magnetic ring 322 attract each other, ensuring the stable positioning of the valve block 320 in the open position; at the same time, the sleeve surface 121 of the female collar 120 is tightly fitted with the outer surface of the male collar 220, enhancing the sealing performance of the overall structure.

[0063] Final state: Ultimately, the flow channel holes 211 of the first connecting rod 110 and the second connecting rod 210 are fully engaged, forming a stable liquid passage. Even after the external force is removed, the tight fit between the mating surface 121 of the female collar 120 and the outer surface of the male collar 220, along with the magnetic attraction effect of the sealing structure and the collar engagement, ensure that the female connector 100 and the male connector 200 maintain a stable liquid connection in the mating state.
