Description

Technical Field

[0001] This utility model belongs to the field of biomedical instrument and equipment technology, and relates to a multi-channel electric shock tube. Background Technology

[0002] Electroporation (also known as electrotransfection or electroporation) is a process that uses a high-intensity electric field to momentarily increase the permeability of the cell membrane, temporarily making it porous and allowing external materials, such as macromolecules, to pass through. The effectiveness of cell membrane electroporation depends on various parameters of the electric field, such as pulse type, pulse voltage, pulse duration, number of pulses, and other experimental conditions.

[0003] The applicant previously filed a Chinese patent application [Authorization Announcement No.: CN104403943B] disclosing an electroporation tube and a cell electroporation device with an electroporation tube. The electroporation tube includes a tube body, a first electrode, a second electrode, and a stopper. The tube body has a cavity for containing a target liquid sample. One end of the tube body is provided with the first electrode, and the other end of the tube body has an opening communicating with the cavity. The working part of the first electrode is connected to the cavity, and the edge of the opening has an annular end face. The second electrode is disposed in the stopper, and the outer end of the second electrode can be electrically connected to the outside through the opening of the stopper. The inner end face of the second electrode can fit against the annular end face of the opening edge. An elastic element connected to the second electrode is disposed in the stopper. The outer side of the elastic element is connected to the stopper, and the inner side of the elastic element is connected to the second electrode. The periphery of the opening has a positioning structure that can fix the stopper to the end of the tube body and cause the elastic element to undergo compression deformation.

[0004] The above structure allows the tube to be filled with an experimental sample containing cells and the substance to be injected into the cells. The stopper is then placed on the tube to close the opening. The first and second electrodes are connected to a pulsed power supply, and discharge causes the tube to generate an electric field. However, when multiple experimental samples need to be tested, the tube can only hold one sample at a time, which cannot meet the need for simultaneous testing of multiple sets of experiments, resulting in low experimental efficiency. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a multi-channel electric shock tube. The technical problem this invention aims to solve is: how to address the low experimental efficiency of existing electric shock tubes.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A multi-channel electric shock tube includes multiple sample receiving tubes made of insulating material. The sample receiving tubes are fixed in a row, each having a first end opening and a second end opening. The multi-channel electric shock tube also includes a first conductive material component, a cap, and a second conductive material component. The first conductive material component seals the first end opening of the sample receiving tube, and when the cap is placed on the sample receiving tube, the second conductive material component seals the second end opening of the sample receiving tube. The first and second conductive material components are generally made of metals such as aluminum, copper, or steel.

[0008] By using multiple sample receiving tubes, the first opening of each tube is sealed with a first conductive material. The tubes are filled with a liquid sample containing cells and substances to be injected into the cells. The multi-channel electroconvulsive tube also has a cap, the second opening of which is sealed with a second conductive material. This design, with multiple sample receiving tubes fixed in a row, allows for the placement of multiple liquid samples in their respective tubes during experiments. By then energizing the first and second conductive materials, multiple samples can be processed, thereby improving the experimental efficiency of the electroconvulsive tube.

[0009] In the aforementioned multi-channel electric shock tube, there are multiple first conductive material components, and each first conductive material component is arranged in a one-to-one correspondence with a sample receiving tube.

[0010] Multiple first conductive material components can be provided, each corresponding to a sample receiving tube, and each component can seal the first end opening of the corresponding sample receiving tube. In this case, the first conductive material component can be directly embedded into the sample receiving tube to seal the first end opening, thereby ensuring better experimental results.

[0011] In the aforementioned multi-channel electric shock tube, a first conductive material component is provided and is elongated. The first conductive material component is located below all sample receiving tubes and seals the first end opening of the sample receiving tube.

[0012] The first conductive material component adopts a long strip design, which allows one first conductive material component to seal all sample receiving tubes, improving the convenience of sealing the sample receiving tubes.

[0013] Furthermore, the first conductive material component can be in the form of a long strip.

[0014] In the aforementioned multi-channel electric shock tube, multiple covers are provided, each corresponding to a sample receiving tube. Adjacent covers are fixed together by connecting strips, and each cover contains a second conductive material component.

[0015] By providing multiple covers, with adjacent covers connected by connecting strips, the covers can be separated from each other while also being quickly and stably snapped together, improving the ease of use of multi-channel electric shock tubes and increasing experimental efficiency.

[0016] The connecting strip can be integrally formed with the cover, or it can be a separate component that connects multiple covers by means of its shape.

[0017] In the aforementioned multi-channel electric shock tube, the cover is provided and is elongated, and multiple second conductive material components are provided, with the second conductive material components located within the cover.

[0018] This structure allows the second conductive material component to quickly and synchronously seal the second end opening of the sample container tube as the cover closes, improving the sealing effect and facilitating rapid experiments with multiple sample container tubes.

[0019] In the aforementioned multi-channel electric shock tube, the cover is provided and is elongated, and the second conductive material component is provided and is elongated. The second conductive material component is disposed within the cover, and after the cover is closed, the second conductive material component seals the second end opening of the sample receiving tube.

[0020] The use of a long strip-shaped second conductive material component allows for simultaneous and rapid sealing of the second end opening of the sample container tube during the closing process, improving closing efficiency and thus enhancing experimental efficiency.

[0021] In the aforementioned multi-channel electric shock tube, the sample receiving tube is made of an elastic material, and the edge of the sample receiving tube is squeezed and deformed when the second conductive material component seals the second end opening of the sample receiving tube.

[0022] Similarly, the sample container tube is made of an elastic material, and when the first conductive material component seals the first end opening of the sample container tube, the edge of the sample container tube can also be deformed by compression. The sample container tube is generally made of polymers such as plastic, silicone, and rubber. When using elastic materials such as silicone, rubber, or PVC, the main body of the sample container tube can be thicker, while the first and second end openings can have relatively thin sealing ribs. The thinner sealing ribs are easily deformed under pressure to ensure a tight seal, while the thicker main body can withstand pressure and maintain the shape of the sample container tube.

[0023] By using an elastic material, the second or first conductive material component can be deformed by compression when sealing the sample container tube, thus ensuring the sealing effect inside the sample container tube and improving the stability of the experiment.

[0024] In the aforementioned multi-channel electric shock tube, multiple sample receiving tubes form a multi-unit sample receiving tube, with a clearance gap between two adjacent sample receiving tubes.

[0025] The multi-unit sample receiving tube can consist of 4, 6, or 8 sample receiving tubes, and can be manufactured using injection molding, facilitating installation and production, and reducing production and installation costs. Alternatively, the multi-unit sample receiving tube can be connected by a single connector with multiple insertion holes for inserting multiple sample receiving tubes. Furthermore, the connector can also be part of the first conductive material component, which has multiple conductive protrusions corresponding one-to-one with the sample receiving tubes, allowing each sample receiving tube to be fitted onto one of the protrusions to form a connection.

[0026] By designing a clearance gap, when the liquid in the sample container is slightly overflowing, the small amount of overflowing liquid will be squeezed out during the pressing down of the cap. The squeezed-out liquid will flow between two adjacent sample containers, rather than into adjacent sample containers, thus preventing contact between the liquids of two adjacent samples and affecting the experiment. Generally, it is sufficient to slightly overflow the sample; the small amount of squeezed-out liquid will adhere to the vicinity of the nozzle and is unlikely to flow into adjacent samples.

[0027] In the aforementioned multi-channel electric shock tube, the second conductive material component has a transversely spaced groove that corresponds one-to-one with the clearance gap.

[0028] By setting up interval grooves that correspond one-to-one with the clearance gaps, the liquid squeezed out from the sample receiving tube will flow out and adhere along the second conductive material component. The interval grooves can prevent the squeezed liquid from flowing to the vicinity of the adjacent sample receiving tube opening, thereby improving experimental efficiency while ensuring experimental stability.

[0029] In the aforementioned multi-channel electric shock tube, one or more clearance openings are provided at the upper end of the cover. All clearance openings are distributed along the length direction of the cover. When the cover is closed, the second conductive material component is located below the clearance openings.

[0030] The design of the clearance port allows external current to be introduced into each sample container tube when the second conductive material component is electrically connected to the outside, thereby improving the experimental efficiency of simultaneous experiments in multiple sample container tubes.

[0031] In the aforementioned multi-channel electric shock tube, the multi-channel electric shock tube also includes a long strip-shaped box body, the multi-sample receiving tube is disposed in the box body, the bottom of the box body has a connection port, the bottom of the box body is snapped with a mounting base, the aforementioned first conductive material component is installed in the mounting base, the first conductive material component is located below the connection port.

[0032] A mounting base is snapped into the bottom of the box. By placing the first conductive material component inside the mounting base, the box and the mounting base can press the first conductive material component onto the sample receiving tube through the clamping force during installation, which improves the sealing of the lower end of the sample receiving tube and ensures the stability of the experiment.

[0033] In the aforementioned multi-channel electric shock tube, a frame is connected inside the box. The frame has mounting holes that correspond one-to-one with the sample receiving tubes. The outer side wall of the sample receiving tube has an outwardly protruding limiting flange. The sample receiving tube passes through the corresponding mounting hole, and the lower end face of the frame abuts against the upper end face of the limiting flange.

[0034] The frame design makes it easier to install the sample receiving tube inside the box. The limiting edge design ensures that the first conductive material not only conducts electricity but also presses the limiting edge of the sample receiving tube against the frame, thus positioning the sample receiving tube and improving the installation stability of the multi-channel electric shock tube.

[0035] In the aforementioned multi-channel electric shock tube, the sample receiving tubes are all hollow cylinders, and two adjacent sample receiving tubes are connected by a connecting component, the upper end of which abuts against the lower end face of the frame.

[0036] The design of the connecting components facilitates the quick installation of the sample receiving tube into the box, making the installation of the entire multi-channel electroshock tube convenient.

[0037] In the aforementioned multi-channel electric shock tube, the connecting component is disposed at the lower end of the sample receiving tube and connects the lower end of the sample receiving tube, and the aforementioned clearance gap is formed between the upper ends of two adjacent sample receiving tubes.

[0038] Because the lower end of the sample container tube is always in contact with the first conductive material component, when liquid is injected into the corresponding sample container tube and slightly overflows, the liquid overflows from the upper opening when the sample container tube is pressed down by the second conductive material component. Therefore, by setting a clearance gap at the upper end of the sample container tube, the liquids in two adjacent sample container tubes will not interfere with each other, and the position of the connecting component can also improve the installation efficiency of multi-unit sample container tubes while ensuring the stability of the experiment.

[0039] In the aforementioned multi-channel electric shock tube, card interfaces can be provided on the front and rear side walls of the box body, and the mounting base has elastic card blocks that correspond one-to-one with the card interfaces. The elastic card blocks are embedded in the corresponding card interfaces and connect the mounting base to the box body.

[0040] In the above structure, the positions of the card interface and the elastic card block can also be interchanged, and the card connection function can still be completed.

[0041] In the aforementioned multi-channel electric shock tube, each of the elastic blocks has a snap-fit ​​end. The elastic block is located inside the box body and the snap-fit ​​end snaps into the corresponding snap-fit ​​interface from inside the box body. There is a gap between the elastic block and the outer wall of the sample receiving tube. The elastic block is located outside the connecting component.

[0042] The elastic locking block is inserted into the corresponding locking interface from the inside of the box. Since the multi-channel electric shock tube needs to be held by hand when pouring the liquid to be electro-polarized during the experiment, the elastic locking block is inserted from the inside of the box, so that it is stably set inside the box and does not protrude from the box. This avoids accidentally touching the elastic locking block and causing the box to separate from the mounting box, thus improving the stability of the multi-channel electric shock tube. The elastic locking block is located on the outside of the connecting block, which makes the mounting box easier and faster to install and remove, further improving the convenience of installation and use.

[0043] In the aforementioned multi-channel electric shock tube, the snap-fit ​​end is located inside the snap-fit ​​interface, and there is a gap between the upper end of the snap-fit ​​end and the wall of the snap-fit ​​interface, while the lower end face of the snap-fit ​​end abuts against the wall of the snap-fit ​​interface.

[0044] The snap-fit ​​design ensures that the entire elastic snap-fit ​​block is located within the outer wall of the housing after installation, preventing accidental contact during use and improving the ease of use of the electric shock tube. The spacing design allows the snap-fit ​​end to have upward movement space within the snap-fit ​​interface, further facilitating the installation of the mounting base.

[0045] In the aforementioned multi-channel electric shock tube, the outer wall of the mounting base is recessed inward to form grooves that correspond one-to-one with the elastic blocks. The grooves are arranged vertically and the lower end of the box is directly opposite the grooves.

[0046] The groove design allows for longitudinal clearance of the elastic block, so that the lower end of the elastic block only needs to rest against the wall of the interface, without any other limiting components below, thus improving the ease of installation.

[0047] In the aforementioned multi-channel electric shock tube, a rotatable connection mechanism is provided between the cover and the housing. The rotatable connection mechanism includes a hinge post disposed on one side of the cover, an upper limit block and a lower limit block protruding on the outer side wall of the housing, a notch for the upper limit block to pass through on the cover, and multiple positioning blocks arranged axially on the hinge post, with the positioning blocks disposed at one end of the upper limit block or the lower limit block.

[0048] This structure allows for a detachable hinged connection between the lid and the box. To enhance the stability of the connection, upper and lower limit blocks are used to improve the stability of the hinged connection between the lid and the box.

[0049] Furthermore, the hinge shaft is located on the outer side wall of the box, so that when the cover is opened, it will not block the connection port at the top of the sample container tube inside the box, making it easier for liquid to be injected into the sample container tube and improving the convenience of using the sample container tube.

[0050] In the aforementioned multi-channel electroporation tube, the rotatable connecting mechanism includes a flexible connecting strip to help maintain the connection between the cover and the box body when they are opened and closed. The flexible connecting strip can be integrally formed with the cover or the box body. The box body and the cover have a matching switch latch on the opposite side wall of the rotatable connecting mechanism. When the switch latch is open, the cover can be opened to allow the addition of a liquid sample. After sample addition is completed, the switch latch is closed, fixing the cover to the box body. At this time, the second conductive material component seals the second end opening of the sample receiving tube, allowing the sample to undergo electroporation experiments. After the electroporation experiment is completed, the switch latch can be opened to remove the liquid sample.

[0051] This invention also provides a method for batch processing multiple sample cells for electroporation. Using the multi-channel electroporation tube of this invention, liquid samples are added when the cap is opened. Generally, multiple samples are added simultaneously using a multi-channel pipette. The samples contain cells and substances to be injected into the cells. During sample addition, the volume of the liquid sample is slightly larger than the volume in the sample receiving tube, resulting in a slightly curved bulge at the top of the liquid sample. After adding the sample, the cap is closed. The second conductive material in the cap contacts the liquid downwards and squeezes the second end opening of the sample receiving tube, forming a seal. After the second end opening is closed, a small amount of squeezed liquid flows out into the clearance gap near the second end opening. At this time, an electroporation instrument releases electrical pulses to the multi-channel electroporation tube to perform the electroporation experiment. After electroporation, the cap is opened, and the samples are removed from the sample receiving tube, generally using a multi-channel pipette. The removed cell samples can be cultured in conventional cell culture plates with wells arranged in rows and columns, or in other types of culture plates.

[0052] The cell culture plates and multichannel pipettes mentioned above are existing structures.

[0053] Compared with existing technologies, this multi-channel electric shock tube has the following advantages:

[0054] 1. By fixing multiple sample receiving tubes in a row, when conducting experiments on multiple liquid samples, multiple liquid samples can be placed in the corresponding sample receiving tubes. Furthermore, multiple samples can be processed in batches by simply energizing the first and second conductive material components, thereby improving the experimental efficiency of the electric shock tube.

[0055] 2. By sealing the opening of the sample receiving tube with the first and second conductive material components, the electrochemical reaction bubbles generated during cell electroporation can be compressed, thereby improving the electroporation efficiency and cell viability in the experiment. The multi-channel electroporation tube has a reliable structure, is easy to operate, and can improve the experimental results.

[0056] 3. A mounting base is snapped into the bottom of the box. By placing the first conductive material component inside the mounting base, the box and the mounting base can press the first conductive material component tightly onto the sample receiving tube during installation through the snapping force, which improves the sealing of the lower end of the sample receiving tube and ensures the stability of the experimental device.

Detailed Implementation

[0069] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0070] Example 1

[0071] like Figure 1-3 As shown, this multi-channel electric shock tube includes multiple sample receiving tubes 8 made of insulating material, which are fixed in a row. Each sample receiving tube 8 has a first end opening 81 and a second end opening 82. The multi-channel electric shock tube also includes a first conductive material component 21, a cover 4, and a second conductive material component 41. The first conductive material component 21 seals the first end opening 81 of the sample receiving tube 8.

There are multiple first conductive material components 21, and each first conductive material component 21 is arranged in a one-to-one correspondence with a sample receiving tube 8.

[0072] By setting up multiple sample receiving tubes 8, the sample receiving tubes 8 are filled with liquid samples containing cells and substances to be injected into the cells.

The second end opening 82 of the cover 4 is sealed by the second conductive material component 41. The design of multiple sample receiving tubes 8 fixed in a row allows multiple liquid samples to be placed in the corresponding sample receiving tubes 8 when conducting experiments on multiple liquid samples. Then, the first conductive material component 21 and the second conductive material component 41 are energized to achieve the purpose of improving experimental efficiency by electrostatically processing multiple samples.

[0073] like Figure 1 and Figure 3As shown, the sample receiving tube 8 is made of elastic material. When the second conductive material component 41 seals the second end opening 82 of the sample receiving tube 8, the edge of the sample receiving tube 8 is squeezed and deformed. There are multiple cover bodies 4, which are arranged one-to-one with the sample receiving tubes 8. Adjacent cover bodies 4 are fixedly connected by connecting strips 9. The cover body 4 is provided with a second conductive material component 41.

The second conductive material part 41 is disposed inside the cover 4. After the cover 4 is closed, the second conductive material part 41 seals the second end opening 82 of the sample receiving tube 8. Multiple sample receiving tubes 8 form a multi-unit sample receiving tube 7. There is a clearance gap 5 between two adjacent sample receiving tubes 8. The multi-unit sample receiving tube 7 is injection molded. The second conductive material part 41 has transverse openings that correspond one-to-one with the clearance gaps 5. The cover 4 has a spacer slot 41a, and a clearance opening 42 is provided at the upper end of the cover 4. All clearance openings 42 are distributed along the length of the cover 4. The second conductive material component 41 is located below the clearance opening 42. The multi-channel electric shock tube also includes a long strip-shaped box 1. The multi-sample receiving tube 7 is set inside the box 1. A connection port 12 is provided at the bottom of the box 1. The bottom of the box 1 is snapped with a mounting base 2. The first conductive material component 21 is installed inside the mounting base 2. The first conductive material component 21 is located below the connection port 12.

[0080] like Figure 4-9As shown, a frame 6 is connected inside the box body 1. The frame 6 has mounting holes 61 that correspond one-to-one with the sample receiving tubes 8. The outer side wall of the sample receiving tube 8 has an outwardly protruding limiting flange 33. The sample receiving tube 8 passes through the corresponding mounting hole 61 and the lower end face of the frame 6 abuts against the upper end face of the limiting flange 33. Two adjacent sample receiving tubes 8 are connected by a connecting component 34. The connecting component 34 is integrally formed with the sample receiving tube 8. The upper end of the connecting component 34 abuts against the lower end face of the frame 6. The connecting component 34 is located at the lower end of the sample receiving tube 8 and connects the lower end of the sample receiving tube 8. The aforementioned clearance gap 5 is formed between the upper ends of two adjacent sample receiving tubes 8.

[0081] like Figure 6-10 As shown, card interfaces 13 are provided on the front and rear side walls of the box body 1. The mounting base 2 has elastic card blocks 22 corresponding to the card interfaces 13. The elastic card blocks 22 are embedded in the corresponding card interfaces 13, connecting the mounting base 2 to the box body 1. Each elastic card block 22 has a snap-fit ​​end 22a. The elastic card block 22 is located inside the box body 1, and the snap-fit ​​end 22a snaps into the corresponding card interface 13 from the inside of the box body 1. The elastic card block 22 and the outer side wall of the sample receiving tube 8 are... There is a gap 23 between them. The elastic card block 22 is located outside the connecting component 34. The card contact end 22a is located inside the card interface 13. There is a gap 22b between the upper end of the card contact end 22a and the opening wall of the card interface 13. The lower end face of the card contact end 22a abuts against the opening wall of the card interface 13. The outer wall of the mounting base 2 is recessed inward to form a groove 24 that corresponds one-to-one with the elastic card block 22. The groove 24 is arranged vertically and the lower end of the box body 1 is directly opposite the groove 24.

[0082] like Figure 4 and Figure 11 As shown, a rotatable connection mechanism exists between the cover 4 and the box 1. This rotatable connection structure includes a hinge post 43 on one side of the cover, an upper limit block 14 and a lower limit block 15 protruding from the outer wall of the box 1, a notch 44 for the upper limit block 14 to pass through on the cover 4, and multiple positioning blocks 43a arranged axially on the hinge post 43, each positioning block 43a located at one end of either the upper limit block 14 or the lower limit block 15. A fastening plate 45 is provided on the other side of the cover 4, with a fastening interface 45a. A fastening block 16, embedded in the fastening interface 45a, protrudes outward from the outer wall of the box 1. The fastening plate 45 and the fastening interface 45a further enhance the stability of the connection between the cover 4 and the box 1.

[0083] Example 5

[0084] The content of this embodiment is basically the same as that of Embodiment 1, except that:

[0085] The rotatable connection mechanism includes a flexible connecting strip to help maintain the connection between the cover 4 and the box 1 when they are opened and closed. The flexible connecting strip can be integrally formed with the cover 4 or the box 1. The box 1 and the cover 4 have matching switch latches on the opposite side wall of the rotatable connection mechanism. When the switch latches are open, the cover 4 can be opened to allow the addition of a liquid sample. After the sample is added, the switch latches are closed, fixing the cover 4 to the box 1. At this time, the second conductive material 41 seals the second end opening 82 of the sample receiving tube 8, allowing the sample to undergo an electroporation experiment. After the electroporation experiment is completed, the switch latches can be opened to remove the liquid sample.
