Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a connector and a drain connector. Background Technology

[0002] Hemodialysis is a key treatment for acute and chronic renal failure and the accumulation of drugs or other toxins in the body. During dialysis, blood and dialysate exchange substances through diffusion, convection, and ultrafiltration to achieve a dynamic balance.

[0003] During dialysis, the patient, dialyzer, and dialysis machine are interconnected via extracorporeal circulation tubing, and the various connectors on this tubing are the core components for achieving a closed-loop extracorporeal circulation system. During the pre-filling phase, the drain connector is used to connect the extracorporeal circulation tubing to the drain port of the dialysis machine. However, after pre-filling or dialysis, when the extracorporeal circulation tubing needs to be separated from the patient, dialyzer, and dialysis machine, residual liquid (such as blood, dialysate, or pre-filling fluid) often remains at the connector joints. This liquid can easily drip during separation, contaminating the dialysis unit floor, fostering bacterial growth, and increasing the risk of infection for the patient. Currently, commonly used separation procedures in clinical practice cannot effectively prevent the dripping of residual liquid from the connector joints and the resulting contamination and infection risks.

[0004] Therefore, how to solve the problem of residual liquid dripping from the joint that cannot be avoided in existing separation operations is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a connector that can effectively prevent liquid from dripping onto the floor of the dialysis department, thereby avoiding contamination and infection caused by liquid dripping.

[0006] Another objective of this invention is to provide a drain connector including the aforementioned connector, which can prevent residual liquid from dripping from the connector.

[0039] 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.

[0040] 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.

[0041] It should be noted that the directional terms such as "left" and "right" in the following text are defined based on the accompanying drawings in the instruction manual.

[0042] The core of this invention is to provide a connector that effectively prevents liquid from dripping onto the floor of the dialysis room, thereby avoiding contamination and infection caused by dripping liquid. Another core aspect of this invention is to provide a drainage connector including the aforementioned connector, which can prevent residual liquid from dripping from the connector.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 A connector includes a connector body 1 and a receiver 2.

[0044] Specifically, the outer periphery of the connector body 1 is provided with a limiting groove 11 extending along the length direction, and the receiver 2 is provided with a sliding part that is slidably connected to the limiting groove 11, so that the receiver 2 can move flexibly on the connector body 1. Medical staff can quickly adjust the position of the receiver 2 according to actual operational needs. When the receiver 2 is in the receiving state, it extends beyond the end of the connector body 1 to receive the liquid dripping from the connector connection, which can effectively prevent the liquid from dripping onto the floor of the dialysis department, thereby avoiding contamination and infection caused by the liquid dripping. When not in the receiving state, the receiver 2 does not extend beyond the end of the connector body 1, so it will not hinder the medical staff's dialysis machine loading and unloading operations, ensuring the smooth progress of dialysis operations. The receiver 2 is provided with a water-absorbing structure 3, which can quickly absorb the dripping liquid, prevent liquid splashing and overflow, and enhance the anti-contamination effect. Even when the liquid dripping volume is large, it can effectively avoid the risk of contamination and infection caused by the liquid dripping.

[0045] The connector body 1 is a circular tube structure with an internal liquid channel. This optimizes fluid dynamics, ensuring smooth liquid flow within the channel, resulting in lower fluid resistance and effectively reducing energy loss during transport. This ensures smooth flow of dialysate or blood, minimizes turbulence and pressure loss, and improves the efficiency of liquid transport during dialysis. The circular tube structure of the connector body 1 is simple to design, easy to manufacture and process, reduces production costs, and increases production efficiency.

[0046] The connector designed in the above manner cleverly incorporates a sliding receiver 2 on the connector body 1, specifically designed to absorb liquid dripping during connector separation. This effectively prevents liquid from splashing or dripping onto the dialysis room floor, thus preventing bacterial growth and significantly reducing the risk of infection for patients. It not only improves the safety and hygiene of dialysis procedures but also provides a cleaner and safer medical environment for medical staff and patients.

[0047] Please refer to Figure 4 and Figure 5 The receiver 2 is slidably connected to the connector body 1 via the connecting rod 4. One end of the connecting rod 4 is provided with a sliding part, and the other end of the connecting rod 4 is connected to the receiver 2.

[0048] It should be noted that one end of the connecting rod 4 is equipped with a sliding part, which cooperates with the limiting groove 11 on the connector body 1 to ensure that the receiver 2 always stays on the predetermined track during sliding, avoiding deviation and further enhancing the stability of the connection. The sliding connection design between the connecting rod 4 and the connector body 1 allows the receiver 2 to move flexibly on the connector body 1. Medical staff can quickly adjust the position of the receiver 2 according to actual operational needs, adapting to different operating scenarios and improving the flexibility and convenience of operation. The sliding connection method makes the movement of the receiver 2 simple and quick. When performing dialysis on / off operations, medical staff can quickly slide the receiver 2 to the required position without affecting the normal dialysis operation process, improving work efficiency. The other end of the connecting rod 4 is connected to the receiver 2 by a snap-fit ​​connection. This connection method is simple and reliable, ensuring that the receiver 2 will not loosen or fall off during use, improving the stability and reliability of the entire connector structure.

[0049] Specifically, a through hole can be provided on the connector 2, into which the connecting rod 4 can be inserted to achieve an effective connection between the connector 2 and the connecting rod 4. Connecting the connector 2 and the connecting rod 4 through the through hole allows for easy disassembly and reassembly. The through hole design provides a stable connection point, ensuring a firm and reliable connection between the connecting rod 4 and the connector 2, reducing the risk of loosening or detachment due to insecure connections, and improving the overall stability of the joint structure.

[0050] In practical applications, the other end of the connecting rod 4 can also be connected to the receiver 2 by a threaded connection, or the connecting rod 4 and the receiver 2 can be made into an integral structure without any restrictions.

[0051] Please refer to Figure 6 The sliding part is a sliding block 41 located on both sides of the connecting rod 4. The limiting groove 11 is provided with a side groove 12, and the sliding block 41 is slidably arranged along the side groove 12.

[0052] It is understood that the sliding part of the connecting rod 4 consists of sliding blocks 41 on both sides. The sliding blocks 41 are embedded in the side grooves 12 and can slide within them, thus driving the connector 2 to slide. The sliding blocks 41, located on both sides of the connecting rod 4, cooperate with the side grooves 12 within the limiting groove 11, providing precise guidance for the sliding of the connector 2. This ensures that the connector 2 always moves along a predetermined trajectory during sliding, avoiding the risk of deviating from the track and improving the accuracy and reliability of the operation. The design of the side grooves 12 provides stable support for the sliding blocks 41, reducing wobbling and offset during sliding, ensuring that the connector 2 remains stable during sliding, and improving the stability of the entire joint structure. The sliding blocks 41, located on both sides of the connecting rod 4, provide double support, enhancing the structural strength of the connecting rod 4, enabling it to withstand greater forces, thereby improving the durability and reliability of the entire joint. The sliding block 41 slides along the side groove 12, allowing the position of the receiver 2 to be flexibly adjusted. Medical staff can quickly slide the receiver 2 to the required position according to actual operational needs, adapting to different operating scenarios and improving operational flexibility and convenience. This design makes the sliding operation of the receiver 2 simple and quick. When performing dialysis on / off operations, medical staff can quickly slide the receiver 2 to the required position without affecting the normal dialysis operation process, thus improving work efficiency. The cooperative design of the sliding block 41 and the side groove 12 makes the entire connector structure more compact, reducing additional space occupation and making the entire connector smaller, facilitating operation in limited spaces and improving the overall layout rationality of the equipment.

[0053] The length of the limiting groove 11 is 1 / 3 to 3 / 5 of the overall length of the connector body 1. This allows for precise control of the sliding range of the receiver 2, ensuring effective coverage of the end of the connector body 1 when in the receiving state. This prevents liquid from splashing or dripping onto the dialysis room floor, reducing the risk of contamination and bacterial growth, and improving the hygiene of the dialysis environment. When not in the receiving state, it does not interfere with operation. However, in practical applications, the length of the limiting groove 11 is not limited and can be designed according to actual conditions.

[0054] Please refer to Figure 6 and Figure 7 One end of the connector body 1 is provided with a connecting part, which is either a threaded connecting section 5 or a sliding component connecting section 6.

[0055] It should be noted that the threaded connection section 5 provides a tight connection through its helical structure, effectively preventing liquid leakage and ensuring normal fluid flow during dialysis, thus improving the reliability and safety of the connection. Threaded connection section 5 offers a robust and reliable connection method, suitable for scenarios requiring a tight connection that is not easily loosened, such as connecting to the drain port of the dialysis machine, ensuring connection stability during dialysis. The sliding component connection section 6 provides a flexible connection method, suitable for scenarios requiring rapid connection and disconnection, such as when frequent replacement or adjustment of connection parts is needed during dialysis, enabling quick operation and improving work efficiency.

[0056] Please refer to Figure 1 and Figure 2 The sliding component connecting section 6 includes a connector 61. A limiting part 62 is sleeved on one end of the connector 61 near the middle of the connector body 1. A limiting groove with the limiting part 62 and the connector body 1 is formed with the limiting part recessed inward around the perimeter. A sliding connector cap 63 is sleeved on the limiting groove. The connector cap 63 is used to fix the connector body 1 and the drain port of the dialysis machine.

[0057] Understandably, the sliding component connecting section 6, through the design of the sliding connector cap 63 and the limiting part 62, provides a flexible connection method, enabling quick fixing and release of the connector, ensuring that liquid leakage or component detachment will not occur due to loose connection during operation. In use, the connector 61 can be inserted into the drain port of the dialysis machine. The connector cap 63 has an internal thread that matches the external thread of the drain port. By rotating the connector cap 63, it slides along the limiting groove. When the connector cap 63 connects to the drain port, it fixes the connector body 1 to the drain port, tightly securing the connector body 1 to the dialysis machine's drain port, effectively preventing liquid leakage and ensuring normal liquid flow during dialysis. The design of the sliding connector cap 63 allows for quick connection and disconnection, allowing medical personnel to quickly connect or disconnect the connector body 1 from the dialysis machine's drain port, significantly improving the efficiency of dialysis operations, especially when frequent replacement or adjustment of connecting components is required. The operation of the sliding connector cap 63 is simple and intuitive, reducing operation steps and time.

[0058] The limiting part 62 and the connector body 1 form a limiting groove with inward inwards on all four sides. It can be understood that the outer diameters of both the limiting part 62 and the connector body 1 are larger than the outer diameter of the limiting groove. The limiting groove is used to install the connector cap 63, which can slide relative to the limiting groove. This provides a clear limit for the connector cap 63, ensuring that it will not disengage from the limiting groove during sliding, thereby enhancing the stability of the connection. This limiting design effectively prevents the connector cap 63 from loosening or falling off due to external force or vibration during use, improving the reliability of the entire connector structure. The sliding function of the connector cap 63 allows medical personnel to quickly adjust its position, ensuring rapid connection and disconnection during dialysis, improving operational convenience and efficiency. The design of the limiting part 62 and the connector cap 63 makes the entire connector structure more compact, reducing additional space occupation, facilitating operation in limited spaces, and improving the overall layout rationality of the equipment.

[0059] Based on the above embodiment, the connector 61 has a tapered structure.

[0060] It should be noted that the conical connector 61 design allows for easier insertion into the dialysis machine's drain port or other connecting components, reducing the force required for insertion and making the connection operation smoother, thus improving convenience and efficiency. The tapered tip allows for more precise alignment with the drain port, reducing insertion difficulties caused by inaccurate alignment. When inserted into the drain port, the conical connector 61 forms a tight fit with the inner wall of the drain port, effectively preventing liquid leakage, improving the connection's sealing performance, reducing the risk of liquid leakage at the connection point, ensuring normal fluid flow during dialysis, and enhancing the safety and reliability of the dialysis operation.

[0061] In practice, please refer to Figure 1When connecting the connector body 1 and connector cap 63 to the dialysis machine's drain port, medical staff will slide the receiver 2 to the leftmost end of the limiting groove 11 to facilitate the connection operation. When separating the connector body 1 and connector cap 63 from the dialysis machine's drain port, medical staff will slide the receiver 2 to the rightmost end of the limiting groove 11 to prevent liquid splashing or dripping and contamination during the separation operation. When the connecting rod 4 slides to the rightmost end of the limiting groove 11, the rightmost end of the receiver 2 is 3-5 mm away from the rightmost end of the connector body 1 in the horizontal direction. The part of the receiver 2 that protrudes from the connector body 1 can effectively receive the liquid dripping from the connector body 1 and the dialysis machine drain port. The dripping liquid is then absorbed by the absorbent layer 31, thus avoiding the risk of contamination caused by liquid splashing or dripping during the dialysis process. When the connecting rod 4 slides to the leftmost end of the limiting groove 11, the rightmost end of the receiver 2 is located to the left of the connector cap 63. The right end of the limiting groove 11 is 1-2 mm away from the left end of the connecting part. This design ensures that the receiver 2 will not cause any obstruction to medical staff when it is in this position for dialysis machine operation.

[0062] In the above embodiment, the receiver 2 is a semi-cylindrical shell. It is concentric with the connector body 1, and its radius is 5-6 mm larger than the maximum radius of the connector body 1. The semi-cylindrical shape of the receiver 2 provides a larger receiving area, effectively catching liquid dripping from the connector connection and reducing the risk of liquid dripping onto the dialysis room floor. The receiver 2 being concentric with the connector body 1 and having a radius 5-6 mm larger than the maximum radius of the connector body 1 allows the receiver 2 to better cover the end of the connector body 1, ensuring complete coverage in the receiving state and effectively preventing liquid dripping. The semi-cylindrical receiver 2 has a compact structure, reducing additional space occupation and making the entire connector structure more compact, facilitating operation in limited spaces and improving the overall layout rationality of the equipment. In the non-receiving state, the receiver 2 does not extend beyond the end of the connector body 1, thus not interfering with the normal operation of medical staff and ensuring the smooth progress of dialysis operations.

[0063] In a preferred embodiment, the water-absorbing structure 3 includes a water-absorbing layer 31, which is disposed on the inner surface of the receiver 2.

[0064] It should be noted that the absorbent layer 31 can quickly absorb liquid dripping from the connector joint, preventing splashing or accumulation when liquid drips into the receiver 2, further reducing the risk of liquid dripping onto the dialysis room floor. The absorbent properties of the absorbent layer 31 effectively prevent liquid splashing and overflow, ensuring complete absorption even in cases of large liquid drips, further improving the anti-fouling effect and ensuring a clean and hygienic dialysis operating environment. The absorbent layer 31 can be directly adhered to the inner surface of the receiver 2 and completely cover the inner wall of the receiver 2, ensuring that liquid dripping from different directions is effectively absorbed, thus improving the protective effect of the receiver 2.

[0065] Furthermore, the receiver 2 has Velcro closures inside, and the absorbent layer 31 is attached to the receiver 2 via Velcro. This allows medical staff to quickly replace the absorbent layer 31 as needed, ensuring the hygiene and reliability of the equipment. It also simplifies and facilitates the replacement and cleaning of the absorbent layer 31, without affecting normal dialysis procedures, improving work efficiency, reducing maintenance time and costs, and extending the equipment's lifespan. The absorbent layer 31 effectively absorbs dripping liquid, reducing the likelihood of liquid dripping onto the dialysis ward floor, lowering the risk of bacterial growth, and improving the hygiene of the dialysis environment.

[0066] In one feasible embodiment, the absorbent layer 31 is fixed to the inner surface of the receiver 2 by a snap-fit ​​structure. The snap-fit ​​can be designed at the edge of the absorbent layer 31, and quick installation and removal are achieved by engaging with slots provided on the inner wall of the receiver 2. In another feasible embodiment, the absorbent layer 31 is fixed to the inner surface of the receiver 2 by an embedded structure. The inner wall of the receiver 2 can be designed with a grooved structure, and the absorbent layer 31 can be embedded in these grooves for a secure fixation. In yet another feasible embodiment, the absorbent layer 31 is fixed to the inner surface of the receiver 2 by a magnetic material. Magnetic material can be embedded on the back of the absorbent layer 31, and quick installation and removal are achieved by engaging with magnetic adsorption points on the inner wall of the receiver 2. In practical applications, there are no restrictions on the connection method between the absorbent layer 31 and the receiver 2.

[0067] The absorbent layer 31 is made of absorbent material and non-woven fabric, which can quickly absorb dripping liquid, reduce liquid accumulation in the receiver 2, and effectively prevent liquid dripping. The absorbent material includes, but is not limited to, one or more combinations of SAP superabsorbent resin and porous sponge. These materials have high absorbency and rapid absorption capacity, which can effectively reduce liquid dripping and splashing, improve the hygiene level of the dialysis environment, and adapt to different types of liquids (such as blood, dialysate, priming fluid, etc.), improving the versatility and applicability of the connector and reducing the need for equipment replacement due to different liquid types. The thickness of the absorbent layer 31 is 2-3mm. This design makes the entire receiver 2 structure more compact, reduces additional space occupation, and facilitates operation in limited spaces.

[0068] Please refer to Figure 8 The water-absorbing structure 3 includes a water-absorbing layer 31 and a dry microsphere 32. The receiver 2 is provided with a partition 21, which is a microporous plate. A cavity for storing the dry microsphere 32 is formed between the partition 21 and the receiver 2. The outer end face of the partition 21 is provided with the water-absorbing layer 31.

[0069] Understandably, a partition 21 is installed inside the receiver 2. This partition 21 is tightly fitted to the receiver 2 through grooves on both ends and the inner wall of the receiver 2, forming a stable structure. The partition 21 is designed as a microporous plate, with its surface covered with countless tiny pores. These pores not only increase the air permeability of the partition 21 but also provide channels for liquid flow. Above the partition 21, a water-absorbing layer 31 is laid. When liquid drips into the receiver 2, it is first quickly absorbed by this water-absorbing layer 31, effectively reducing the accumulation of liquid in the receiver 2. However, when the amount of dripping liquid is large and exceeds the absorption capacity of the water-absorbing layer 31, the excess liquid will flow smoothly into the lower cavity of the receiver 2 through the small holes on the partition 21. In the cavity below the partition 21, dried microspheres 32 are pre-filled. These dried microspheres 32 are carefully made of porous materials with strong water absorption properties, such as zeolite, bentonite, or soda lime. When liquid not adsorbed by the absorbent layer 31 drips into the cavity below the receiver 2, the drying microspheres 32 exert their strong adsorption effect to further adsorb the liquid, thereby significantly reducing the risk of liquid leakage during separation operations in the receiver 2. This not only improves the efficiency of liquid processing but also enhances the safety and reliability of the entire connector system, providing a more reliable guarantee for dialysis operations.

[0070] The design of the partition 21 and the drying microspheres 32 makes the entire absorbent structure 3 more compact, reducing additional space occupation and making the receiver 2 smaller, facilitating operation in limited spaces. The design of the absorbent structure 3 does not affect the sliding operation of the receiver 2. Medical staff can quickly slide the receiver 2 to the required position according to actual operational needs, adapting to different operational scenarios and improving operational flexibility and convenience.

[0071] Please refer to Figure 9 A drain connector includes three connectors as described above, integrally formed to form a three-way structure. One connector has a sliding component connecting section 6 as its connecting part, while the other two connectors have threaded connecting sections 5. This drain connector adopts a Y-shaped design, consisting of three integrally formed connectors. The sliding component connecting section 6 of one connector allows for flexible and rapid connection and disconnection with the drain port of the dialysis machine, greatly improving operational convenience and efficiency. The other two connectors are tightly connected by a robust reinforcing body 7. This structure not only ensures the stability of the entire drain connector but also provides sufficient support strength to withstand various pressures and external forces that may occur during dialysis. Furthermore, both of these connectors use threaded connecting sections 5, which provides excellent sealing performance and robustness, effectively preventing liquid leakage and ensuring the smooth operation of the dialysis process.

[0072] It should be noted that the three connectors are integrally molded to form a T-junction structure, integrating multiple functions to simultaneously meet the connection needs of different tubing during dialysis, thus improving the integration and functionality of the connector. One connector has a sliding component connection section 6, while the other two connectors have threaded connection sections 5, combining the advantages of quick connection and tight fixation to adapt to different operating scenarios and needs. The sliding component connection section 6 allows for quick connection and disconnection, reducing the time and effort required by medical staff during dialysis operations, especially when frequent replacement or adjustment of connection components is needed, significantly improving operational efficiency. The two threaded connection sections 5 provide a robust and reliable connection, effectively preventing fluid leakage and ensuring normal fluid flow during dialysis, improving connection reliability and stability. The integral molding design of the three connectors makes the entire drain connector structure more compact, reducing additional space occupation, facilitating operation in limited spaces, and improving the overall layout rationality of the equipment.

[0073] In summary, the connector provided by this utility model can solve the problem of liquid dripping and contaminating the dialysis room floor at the connector connection point. The receiver 2 can slide flexibly on the connector body 1, allowing medical staff to quickly slide the receiver 2 to the required position according to actual operational needs, adapting to different operational scenarios and improving operational flexibility and convenience. By setting an absorbent layer 31 or an absorbent layer 31 and drying microspheres 32 inside the receiver 2, it can effectively absorb liquid dripping from the connector connection point, preventing liquid splashing or dripping onto the dialysis room floor and reducing the risk of contamination and bacterial growth.
