Description

Technical Field

[0001] This invention relates to the field of biopharmaceutical technology, and more specifically, to a sterile connector and its method of use. Background Technology

[0002] Current disposable sterile connectors are assembled using a paper-pulling method. The sterile connector is installed at the ends of the two pipes to be connected and sterilized (by steam or irradiation). The two connectors are then snapped together, and pulling the paper releases a seal between the sealing rings, completing the sterile connection. Liquid can then flow through the pipes. The existing technology relies on pulling the paper release to create a seal between the sealing rings before liquid can flow through the pipes.

[0003] However, the existing method has the following drawbacks: the design relies on the mutual pressing of sealing rings after the paper is pulled apart, which poses a risk of leakage in the pipeline. Summary of the Invention

[0004] In view of the shortcomings of existing methods, this invention proposes a sterile connector and its usage method to solve the technical problem of pipeline leakage caused by insufficient tightness of the connection between the first connector and the second connector in the prior art.

[0005] This invention provides a sterile connector, comprising: a first connector, a second connector, a pull paper, and at least one connecting tube; The second connector is provided with at least one insertion hole, and the connecting tube is movably disposed on the first connector; The end of the second connector where the insertion hole is located is defined as the insertion end, and the end of the first connector in the direction of movement of the connecting tube is defined as the connection end. The insertion end and the connection end are respectively sealed with the paper puller. Specifically, after connecting the plug-in end and the connecting end, all the paper pulls are pulled out so that the plug-in end and the connecting end are connected, and the connecting tube is pushed towards the second connector so that one of the connecting tubes is inserted into a plug-in hole.

[0006] Optionally, a second sealing ring may also be included; The connecting end and / or the plug-in end are provided with a second sealing ring, which is blocked by the paper pull at the end where it is located.

[0007] Optionally, it also includes a first sealing ring, and at least one of the first sealing rings is provided on one of the connecting pipes; When one of the connecting pipes is inserted into a plug hole, at least one of the first sealing rings on the connecting pipe forms a seal with the inner wall of the plug hole.

[0008] Optionally, it also includes an anti-detachment component; The anti-detachment component includes a connector and a backstop component. The connector is disposed at the end of the first connector away from the connecting end. The connector has a through hole, and an insertion hole communicating with the through hole is provided on one side of the connector. The connecting pipe is provided with an abutment block, and the connecting pipe passes through the through hole and is movably mounted on the first connecting member; During the process of a connecting tube moving towards a plug hole until the plugging is completed, the abutment block enters the through hole from outside the through hole, and one end of the anti-retraction member is inserted into the through hole from the insertion hole. The anti-retraction member abuts against the side of the abutment block away from the second connecting member to prevent the connecting tube from exiting the plug hole.

[0009] Optionally, the abutment block is configured as an abutment ring sleeved on the connecting pipe; The end of the anti-reverse component that abuts against the abutting ring is defined as the abutting end. The abutting end includes two support rods forming a locking position in the middle. After the abutting end is inserted into the through hole, the two support rods are arranged opposite to each other on both sides of the connecting tube and abut against the side of the abutting block away from the second connecting component. The locking position is locked onto the connecting tube.

[0010] Optionally, the side wall of the anti-reverse member is provided with a first locking protrusion extending away from the abutting end, and the inner wall of the insertion hole is provided with a second locking protrusion extending towards the through hole. After the anti-reverse member is inserted into the insertion hole, the second locking protrusion locks the first locking protrusion.

[0011] Optionally, one end of the paper puller is defined as the sealing end and the other end as the pull-out end, and the pull-out end is provided with a gripping hole; The sealing end is used to seal the connecting end and the plug-in end. After the plug-in end and the connecting end are connected, the gripping hole of the pull-out end is grasped to pull the paper away.

[0012] Optionally, it also includes a connecting lock, the connecting lock comprising a first latching member and a second latching member; The first fastener is provided on one end and two opposite sides of the first connector, and the second fastener is provided on one end and two opposite sides of the second connector. When the first connector and the second connector are assembled, one of the first fasteners and one of the second fasteners form a fastening connection.

[0013] Optionally, one end of the connecting tube used for insertion into the insertion hole is defined as the front end, and the other end as the rear end. An amplification protrusion ring is provided on the outer wall of the rear end of the connecting tube for tightening when connecting to an external pipe. The outer diameter of the amplification protrusion ring gradually increases from the rear end to the front end.

[0014] Optionally, three connecting tubes are movably disposed on one of the first connectors, and three plug holes are disposed on one of the second connectors.

[0015] Based on the same inventive concept, the present invention provides a method for using a sterile connector, including: S1: Align and splice the connecting end of the first connector and the plug-in end of the second connector; S2: Pull the paper from the connecting end and the insert end to make the connecting end and the insert end connected; S3: Insert a connecting tube into a socket.

[0016] The beneficial technical effects brought about by the technical solutions provided in the embodiments of the present invention include: The paper pull ensures aseptic sealing before the first and second connectors are connected. Furthermore, after the paper is removed, the connecting end of the first connector and the insertion end of the second connector form a first closed connection. Based on this, a second closed connection is formed by pushing the connecting pipe against the insertion hole. Therefore, this invention adds a second closed connection (insertion-type closure) to the existing first closed connection (surface contact closure) between the first and second connectors, enhancing the sealing performance of the connection and greatly preventing leakage from the pipe.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[0023] The sterile connector and its usage method provided by this invention aim to solve the above-mentioned technical problems of the prior art.

[0024] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0025] This invention provides a sterile connector product, the structural schematic of which is shown below. Figures 1 to 3 As shown, it includes: a first connector 10, a second connector 20, a paper puller 30, and at least one connecting tube 40; The second connector 20 is provided with at least one insertion hole 201, and the connecting tube 40 is movably disposed on the first connector 10. The end of the second connector 20 where the insertion hole 201 is located is defined as the insertion end 2011, and the end of the first connector 10 in the direction of movement of the connecting tube 40 is defined as the connecting end 101. The insertion end 2011 and the connecting end 101 are respectively sealed with paper pullers 30. After the insertion end 2011 and the connecting end 101 are connected, all paper pullers 30 are pulled out so that the insertion end 2011 and the connecting end 101 are connected. The connecting tube 40 is pushed in the direction of the second connector 20 so that one connecting tube 40 is inserted into one insertion hole 201.

[0026] In this embodiment, as is known from existing technology, the pull paper 30 is selected as sterile paper. The pull paper 30 pre-seals the connecting end 101 and the insertion end 2011, thereby ensuring that the two ends are not contaminated by the outside before connection. Of course, the pull paper 30 can be pulled away from the connecting end 101 and the insertion end 2011 by external force. For example, in this embodiment, the first connector 10 connects to the male connector, and the second connector 20 connects to the female connector.

[0027] In addition, the insertion hole 201 is a stepped hole. One end of the connecting tube 40 is inserted into the stepped hole and abuts against the bottom of the stepped hole to complete the positioning. The insertion hole 201 can be used for outward liquid flow.

[0028] It can be understood that the first connector 10 is provided with at least one channel, and one connecting tube 40 is movably disposed in one channel. That is, when the number of insertion holes 201 on the second connector 20 is one, the number of channels on the first connector 10 is one, and one channel corresponds to one connecting tube 40.

[0029] The splicing process of the first connector 10 and the second connector 20 is as follows: First, align and abut the connecting end 101 and the insertion end 2011. The connection method between the first connector 10 and the second connector 20 is not limited here; the connection method can be adhesive, screwing, etc. Next, pull the outer end of the pull paper 30 outward to separate the two pull papers 30 from the connection point of the first connector 10 and the second connector 20. At this time, the first connector 10 and the second connector 20 are connected. Finally, push the end of the connecting tube 40 that is away from the second connector 20. The end of the connecting tube 40 closest to the second connector 20 passes through the connecting end 101 and the insertion end 2011 in sequence and is inserted into the insertion hole 201.

[0030] As can be seen from the above, the ends of the first connector 10 and the second connector 20 are connected face to face. Since the two faces are in contact and closed, the gap is relatively difficult to eliminate and the risk of leakage is greater. Therefore, the present invention adds the insertion of the connecting pipe 40 and the insertion hole 201. It can be seen that the insertion method is an embedded closed connection, and its tightness is much greater than that of the face contact type, which greatly reduces the risk of leakage of the pipeline.

[0031] Optionally, it also includes a second sealing ring 60; the connecting end 101 and / or the plug-in end 2011 are provided with the second sealing ring 60, and the second sealing ring 60 is blocked by the paper pull 30 at the end where it is located.

[0032] A recessed groove is provided on the connecting end 101 and / or the plug-in end 2011, and the second sealing ring 60 is disposed in the recessed groove. In this embodiment, the second sealing ring 60 is disposed on the plug-in end as an example. Specifically, the recessed groove surrounds the outer periphery of the plug-in hole 201. When the first connecting member 10 and the second connecting member 20 are spliced, the second sealing ring 60 plays a sealing role at the splice point.

[0033] It should be noted that before the first connector 10 and the second connector 20 are spliced, the second sealing ring 60 is covered and blocked by the pull paper 30 on the insertion end. The second sealing ring 60 only comes into contact with the connection end 101 after the connection end 101 and the insertion end 2011 are connected and the two pull papers 30 are removed.

[0034] Optionally, it also includes a first sealing ring 50, and at least one first sealing ring 50 is provided on a connecting pipe 40; When a connecting pipe 40 is inserted into a plug hole 201, at least one first sealing ring 50 on the connecting pipe 40 forms a seal with the inner wall of the plug hole 201.

[0035] For example, a first sealing ring 50 is provided on a connecting pipe 40. In its initial state, before the connecting pipe 40 is pushed into the insertion hole 201, the first sealing ring 50 is located in the channel of the first connecting member 10, forming an interference fit between the first sealing ring 50 and the channel. In this embodiment, the first sealing ring 50 is positioned close to the end of the connecting pipe 40 used for insertion into the insertion hole 201. Thus, when the connecting pipe 40 is inserted into the insertion hole 201, a seal (i.e., an interference fit) is formed between the first sealing ring 50 and the inner wall of the insertion hole 201.

[0036] Furthermore, the number of first sealing rings 50 can be set to two, with the two first sealing rings 50 arranged along the length of the connecting tube 40. Initially, both first sealing rings 50 are located in the channel of the first connector 10. At this time, the connecting tube 40 is pushed to insert into the insertion hole 201. Ultimately, one first sealing ring 50 on the connecting tube 40 enters the insertion hole 201, while the other remains in the channel. In summary, the connecting tube 40, the insertion hole 201, and the channel of the first connector 10 all form a seal, further enhancing the sealing performance of the sterile connector.

[0037] Optionally, it also includes an anti-detachment component 70; the anti-detachment component 70 includes a plug-in base 71 and a stopper 72. The plug-in base 71 is disposed at one end of the first connector 10 away from the connecting end 101. The plug-in base 71 has a through hole 7101. An insertion hole 7102 communicating with the through hole 7101 is provided on one side of the plug-in base 71. An abutment block 401 is provided on the connecting tube 40. The connecting tube 40 passes through the hole 7101 and is movably disposed on the first connector 10. When a connecting tube 40 moves toward a plug-in hole 201 until the plug-in is completed, the abutment block 401 enters the through hole 7101 from outside the through hole 7101. One end of the stopper 72 is inserted from the insertion hole 7102 and enters the through hole 7101. The stopper 72 abuts against the side of the abutment block 401 away from the second connector 20 to prevent the connecting tube 40 from exiting the plug-in hole 201.

[0038] In this embodiment, the anti-detachment component 70 serves to prevent the connecting pipe 40 from automatically withdrawing from the insertion hole 201. Specifically, as described above, after the connecting pipe 40 is inserted into the insertion hole 201, it indicates that the first connecting member 10 and the second connecting member 20 are connected. At this time, both can be used as pipelines for liquid transportation. To prevent the connecting pipe 40 from automatically withdrawing from the insertion hole 201 during transportation, the anti-detachment component 72 acts on the abutment block 401 in the insertion hole 7102, thereby limiting the connecting pipe 40 and preventing it from automatically withdrawing from the insertion hole 201. When it is necessary to disconnect the connecting pipe 40 from the insertion hole 201, the anti-detachment component 72 should first be withdrawn from the insertion hole 7102 to release its ground limiting effect on the abutment block 401. At this time, the connecting pipe 40 is pulled away from the second connecting member 20, and finally the connecting pipe 40 separates from the insertion hole 201.

[0039] In addition, in the initial state, the abutment block 401 is located outside the through hole 7101. As the connecting tube 40 is pushed into the insertion hole 201 and finally inserted into the insertion hole 201, the abutment block 401 finally enters the through hole 7101 and is aligned with the position of the insertion hole 7102.

[0040] Optionally, the abutment block 401 is configured as an abutment ring sleeved on the connecting pipe 40; the end of the anti-reverse member 72 that abuts against the abutment ring is defined as the abutment end, the abutment end includes two support rods forming a locking position in the middle, after the abutment end is inserted into the through hole 7101, the two support rods are arranged opposite to each other on both sides of the connecting pipe 40 and abut against the side of the abutment block 401 away from the second connecting member 20 respectively, and the locking position is locked onto the connecting pipe 40.

[0041] This embodiment mainly describes the structure of the abutment block 401 as an abutment ring, with two support rods at the abutment end forming a U-shaped structure, and the aforementioned snap-fit ​​position forming the middle of the U-shaped structure. It can be understood that when the anti-retraction member 72 limits the connection tube 40, the U-shaped structure interlocks with the connection tube 40. More importantly, the two support rods form two symmetrical abutment points with the limiting ring on both sides of the connection tube 40, thus providing a stable abutment and limiting effect on the connection tube 40.

[0042] Optionally, the side wall of the anti-reverse member 72 is provided with a first locking protrusion 7201 extending away from the abutting end, and the inner wall of the insertion hole 7102 is provided with a second locking protrusion 72021 extending towards the through hole 7101. After the anti-reverse member 72 is inserted into the insertion hole 201, the second locking protrusion 72021 locks the first locking protrusion 7201.

[0043] In this embodiment, the purpose of setting a first locking protrusion 7201 on the anti-retraction member 72 and a second locking protrusion 72021 on the inner wall of the insertion hole 7102 is to limit the first locking protrusion 7201 by the second locking protrusion 72021. Specifically, during the process of pushing the anti-retraction member 72 into the insertion hole 201, the first locking protrusion 7201 moves from the side of the second locking protrusion 72021 away from the through hole 7101, passes the second locking protrusion 72021, and finally reaches the side of the second locking protrusion 72021 close to the through hole 7101. Thus, the second locking protrusion 72021 limits the first locking protrusion 7201, preventing the anti-retraction member 72 from automatically exiting the insertion hole 7102 and avoiding the failure of the anti-retraction member 72 to limit the connection tube 40.

[0044] More preferably, the first locking protrusion 7201 is a first locking plate, which is set at an angle (preferably 30°) between the anti-retraction member 72 and the side wall. Correspondingly, the second locking protrusion 72021 is a second locking plate, which is set at an angle (preferably 30°) between the second locking plate and the inner wall of the insertion hole 7102. The inner walls of the first locking plate and the second locking plate are cross-engaged, which makes the effect more reliable.

[0045] In the above-mentioned preferred method, at least two first locking protrusions 7201 are provided on the same side of the anti-retraction member 72, and at least two second locking protrusions 72021 are provided on the same inner wall of the insertion hole 7102. Alternatively, first locking protrusions 7201 are provided on two opposite side walls of the anti-retraction member 72, and second locking protrusions 72021 are provided on two opposite inner walls of the insertion hole 7102.

[0046] Optionally, one end of the paper puller 30 is defined as a sealing end and the other end as a pull-out end. The pull-out end is provided with a gripping hole 301. The sealing end is used to block the sealing connection end 101 and the insertion end 2011. After the insertion end 2011 and the connection end 101 are connected, the gripping hole 301 of the pull-out end is gripped to pull the paper puller 30 out.

[0047] As can be seen from the foregoing, the gripping hole 301 at the pull end of the paper puller 30 in this embodiment is designed to facilitate hand gripping when pulling the paper puller 30, thus ensuring that the paper puller 30 is easy to pull out and can be pulled out quickly.

[0048] Optionally, it also includes a connecting lock 80, which includes a first latching member and a second latching member; a first latching member is provided on one end and two opposite sides of the first connecting member 10, and a second latching member is provided on one end and two opposite sides of the second connecting member 20; when the first connecting member 10 and the second connecting member 20 are assembled, a first latching member and a second latching member form a fastening connection.

[0049] As mentioned above, the first connector 10 and the second connector 20 can be fixed by gluing or screwing after being spliced ​​together. This embodiment achieves the detachable splicing of the first connector 10 and the second connector 20 through a snap-fit ​​method. For example, taking the first connector 10 and the second connector 20 as a rectangular volume structure, the second connector 20 has hooks on its two opposite long sides, the first connector 10 has fastening blocks on its two opposite long sides, and one end of the second connector 20 has a locking plate with a locking hole. When the first connector 10 and the second connector 20 are spliced, one hook engages with one fastening block, and the locking plate engages with the locking hole. This snap-fit ​​method offers greater convenience for assembly and disassembly.

[0050] Optionally, the end of the connecting tube 40 used for insertion into the insertion hole 201 is defined as the front end and the other end as the rear end. An amplification protrusion ring 402 for tightening when connecting to an external pipe is provided on the outer wall of the rear end of the connecting tube 40. The outer diameter of the amplification protrusion ring 402 gradually increases from the rear end to the front end.

[0051] Specifically, the amplification ring 402 can be understood as a frustum structure, and the sloping sidewalls of the frustum structure facilitate the insertion of the tubing. More importantly, when one end of the external tubing is inserted into the amplification ring 402, the inner diameter of that end of the external tubing expands, and after passing through the amplification ring 402, the tubing retracts and tightens on the outer wall of the connecting tube 40. In this way, the amplification ring 402 forms a locking position on the inner wall of the connecting tube 40, effectively preventing the external tubing from falling off from the rear end. In addition, an external guide tube can be provided at the end of the insertion hole 201 of the second connector 20 opposite to the insertion end 2011. The end of the external guide tube can be designed similarly to the amplification ring 402, which will not be elaborated here.

[0052] Optionally, see Figures 4 to 7 A first connector 10 is provided with three connecting pipes 40, and a second connector 20 is provided with three insertion holes 201.

[0053] This embodiment mainly illustrates that a sterile connector can include multiple passages formed by multiple connecting tubes 40 and multiple insertion holes 201. Specifically, three connecting tubes 40 are respectively provided with three insertion holes 201, thereby forming three passages. Providing multiple passages on a sterile connector effectively improves its usage efficiency. In addition, a single sheet of paper 30 can simultaneously cover three connecting tubes 40 or three insertion holes 201, effectively reducing the use of paper 30.

[0054] Based on the same inventive concept, this embodiment provides a method for using a sterile connector, including: S1: Align and splice the connecting end 101 of the first connector 10 and the insertion end 2011 of the second connector 20; S2: Remove the paper pull 30 of the connecting end 101 and the paper pull 30 of the insertion end 2011 so that the connecting end 101 and the insertion end 2011 are connected; S3: Insert a connecting tube 40 into a insertion hole 201.

[0055] In conjunction with the foregoing, after the first connector 10 and the second connector 20 are spliced ​​together, all the paper pullers 30 are pulled out so that the root connector 40 can be inserted into the insertion hole 201.

[0056] Furthermore, with the anti-detachment component 70 installed, the connecting tube 40 passes through the through hole 7101. Specifically, the usage process between the connecting tube 40 and the anti-retraction component 72 is as follows: after the connecting tube 40 is inserted into the insertion hole 201, the anti-retraction component 72 is further installed into the insertion hole 7102 and abuts against the side of the block 401 away from the second connecting component 20.
