Description

Technical Field

[0001] This invention relates to the field of cell injection machine applications, specifically to a cell injection machine. Background Technology

[0002] Cell injection technology is widely used in biomedical research, cell therapy, genetic engineering and other fields. Its core purpose is to precisely inject specific cells (such as stem cells and immune cells) into target samples (such as culture dishes, bioreactors, and microfluidic chips) to achieve targeted cell culture, detection or therapeutic applications.

[0003] Existing cell injection equipment typically includes a mechanical transmission module, a liquid delivery module, a control module, and an auxiliary power supply module. The mechanical transmission module often uses a combination of a stepper motor and a driver to position the injection needle to align with the target injection location on the sample. The liquid delivery module is mainly an injection pump, responsible for quantitatively pushing the cell suspension to ensure controllable injection volume. The control module often uses a PLC (Programmable Logic Controller) as the core control unit, with a simple operation panel or host computer software to set parameters and issue commands. The auxiliary power supply module is a switching power supply to provide stable voltage to various electrical components.

[0004] When using cell injection equipment, taking test tubes as culture dishes as an example, the operator places multiple test tubes onto the tube holder and then activates the lifting drive system. The rising of the holder raises multiple sets of test tubes, allowing the injection needles to extend as far into the test tubes as possible. This reduces cell fluid splashing during injection. A single test tube holder is less efficient for cell injection. When the test tubes are placed, the raised rolled edge at the top of the test tube engages with the locking hole of the holder. This means that the operator needs to push the test tube from the bottom to raise it when placing or removing it. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a cell injection machine to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cell injection machine, comprising an injection machine, wherein a tubular cell injection device is provided inside the injection machine, the tubular cell injection device being a second injection device, including a second support plate, a cell injection assembly provided on the side of the second support plate, a movable guide stage provided inside the second support plate, and a test tube rack installed inside the movable guide stage via a linear moving module, the test tube rack including a base plate assembly, the base plate assembly including a mounting plate, multiple sets of test tube sleeves provided on the top of the mounting plate, and multiple sets of first guide rods provided on the top of the mounting plate. Each set of first guide rods is fitted with a first spring. Two sets of movable components are symmetrically and movably mounted on the outside of the multiple sets of first guide rods. The movable components include a movable frame. The side of the movable frame is provided with a limit guide block. The inside of the movable frame is provided with multiple sets of second guide rods. Each set of second guide rods is fitted with a second spring. A shelf assembly is movably mounted between the second guide rods of the two sets of movable components. The shelf assembly includes a mounting frame. The top of the mounting frame is provided with a fitting hole for locking the test tube. The bottom of the mounting frame is provided with a round hole that matches the test tube sleeve. An extension frame is provided at the bottom of the mounting frame.

[0007] The inner side of the movable guide platform is provided with a limiting guide rail, which is used to adjust the height of the limiting guide block, thereby adjusting the height of the movable component of the test tube rack and the shelf component. The side of the second support plate is provided with a lifting component, which is used to adjust the height of the extension rack, thereby adjusting the height of the shelf component.

[0008] By adopting the above technical solution and setting up a test tube rack that can automatically raise the test tubes, the efficiency of test tube placement and retrieval is improved, thereby improving the efficiency of cell injection. The test tube rack is mainly composed of a base plate assembly, a movable assembly, and a shelf assembly, and the three are connected by a spring to be height-adjustable. The bottom assembly includes multiple sets of test tube sleeves for supporting the test tubes.

[0009] When the test tube rack is in the loading position, the movable component and the shelf component are in a low position with the height reduced. At this time, the test tube sleeve and the shelf component are close together. When the test tube is inserted into the fitting hole of the shelf component, the bottom of the test tube is located inside the test tube sleeve, and part of the test tube will be exposed outside the shelf component. In other words, compared with the traditional test tube rack, this application uses a test tube sleeve to support the test tube, so that the test tube can be placed only half the depth, making it more convenient for the staff to place the test tube.

[0010] When the test tube rack completes the test tube loading process and enters the injection station through the linear moving module, the moving components and the rack assembly will automatically rise to a high position under the adjustment of the limiting guide rail. The rising rack assembly will lift the test tube by restricting the rolled edge of the upper edge of the test tube, so that the test tube will be removed from the test tube sleeve. At this time, the test tube is completely supported by the rack. The rolled edge of the upper edge of the test tube and the fitting hole of the rack assembly are mutually locked and limited, which also improves the stability of the test tube placement.

[0011] Similarly, when the test tubes are returned to the loading station after injection, the moving components and the shelf components return to the low position, so that the height of the multiple sets of test tubes is lowered and they are placed back in the multiple sets of test tube sleeves, while the multiple sets of test tubes are exposed, which is also convenient for the staff to take the test tubes.

[0012] The present invention is further configured such that the injection machine is equipped with a cassette cell injection device, which is used to inject cells into a cassette culture dish.

[0013] Preferably, by incorporating a cassette injection device within the injection machine, the machine can inject cells into both test tubes and cassette culture dishes.

[0014] The invention is further configured such that the top of the mounting plate has multiple sets of through slots, which match the extension bracket.

[0015] Preferably, multiple sets of through slots are provided to avoid the extension frame of the shelving assembly, allowing the extension frame to move within the through slots.

[0016] The present invention is further configured such that the top of the test tube sleeve is provided with a flexible material, and the top of the test tube sleeve matches the bottom of the test tube.

[0017] Preferably, by providing a flexible material, such as a rubber layer, at the top of the test tube sleeve to support the bottom of the test tube, the test tube can be stabilized and protected to a certain extent.

[0018] The present invention is further configured such that the limiting guide block and the limiting guide rail of the active component are matched, the limiting guide block slides inside the limiting guide rail, and the limiting guide rail can change the height of the limiting guide block when the limiting guide block slides.

[0019] Preferably, by setting a limiting guide rail, when the test tube rack moves, the limiting guide block and the limiting guide rail interact to increase the height of the limiting guide block, thereby changing the height of the movable component and the rack assembly installed on top of it. In other words, the movable component and the rack assembly raise the height of multiple sets of test tubes.

[0020] The present invention is further configured such that multiple sets of the shelf assembly are provided between the two sets of movable components, and the mounting brackets of the multiple sets of shelf assemblies are all movably connected through the second guide rod of the movable component.

[0021] Preferably, by setting up multiple sets of shelf components, the test tube shelf can accommodate multiple sets of test tubes at the same time.

[0022] The present invention is further configured such that the injection machine is provided with a tubular cell injection device, which is a first injection device. The first injection device includes a first support plate, a cell injection assembly is provided on the side of the first support plate, and a lifting platform is installed on the side of the first support plate by means of a lifting assembly. The top of the lifting platform is provided with a fitting hole for locking the test tube.

[0023] Preferably, by setting up a lifting platform whose height is adjustable by a lifting component, the test tube can also be locked in place, thereby enabling cell injection.

[0024] The present invention is further configured such that the fitting hole opened on the top of the lifting platform and the mounting frame matches the rolled edge of the upper edge of the test tube, and the fitting hole is larger than the outer wall diameter of the test tube.

[0025] Preferably, by opening a fitting hole larger than the outer wall of the test tube, it is easier to insert the test tube, and the fitting hole matches the rolled end of the test tube, making it easier for the lifting platform or mounting frame to lift the test tube.

[0026] In summary, the present invention has the following main beneficial effects:

[0027] 1. This invention improves the efficiency of placing and retrieving test tubes by setting up a test tube rack that can automatically raise the test tubes, thereby improving the efficiency of cell injection. The test tube rack is mainly composed of a base plate assembly, a movable assembly, and a shelf assembly, and the three are connected by a spring to make the height adjustable. The bottom assembly includes multiple sets of test tube sleeves for supporting the test tubes.

[0028] When the test tube rack is in the loading position, the movable component and the shelf component are in a low position with the height reduced. At this time, the test tube sleeve and the shelf component are close together. When the test tube is inserted into the fitting hole of the shelf component, the bottom of the test tube is located inside the test tube sleeve, and part of the test tube will be exposed outside the shelf component. In other words, compared with the traditional test tube rack, this application uses a test tube sleeve to support the test tube, so that the test tube can be placed only half the depth, making it more convenient for the staff to place the test tube.

[0029] When the test tube rack completes the test tube loading process and enters the injection station through the linear moving module, the moving components and the rack assembly will automatically rise to a high position under the adjustment of the limiting guide rail. The rising rack assembly will lift the test tube by restricting the rolled edge of the upper edge of the test tube, so that the test tube will be removed from the test tube sleeve. At this time, the test tube is completely supported by the rack. The rolled edge of the upper edge of the test tube and the fitting hole of the rack assembly are mutually locked and limited, which also improves the stability of the test tube placement.

[0030] Similarly, when the test tubes are returned to the loading station after injection, the moving components and the shelf components return to the low position, so that the height of the multiple sets of test tubes is lowered and they are placed back in the multiple sets of test tube sleeves, while the multiple sets of test tubes are exposed, which is also convenient for the staff to take the test tubes.

[0031] 2. This invention, by setting multiple sets of shelf components inside the test tube rack, allows the test tube rack to hold more test tubes simultaneously. When the test tube rack moves to the cell injection station, the lifting component works in conjunction with the horizontal linear movement of the test tube rack to lift up the multiple sets of shelf components one by one, so that they actively approach the cell injection component. More test tubes are used in a single cell injection, which can reduce the frequency of staff placing and retrieving test tubes, thereby improving the overall work efficiency of cell injection.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] The embodiments of the present invention will now be described.

[0048] Example 1: Please refer to Figure 1 and Figure 2 A cell injection machine, wherein the injection machine 1 is internally equipped with a tubular cell injection device, which is a first injection device 3. The first injection device 3 includes a first support plate 301. A cell injection assembly 4 is provided on the side of the first support plate 301. The cell injection assembly 4 includes an injection needle, an injection system and a control system. A lifting platform 302 is installed on the side of the first support plate 301 through a lifting assembly. The top of the lifting platform 302 has a locking hole for locking the test tube. By setting the height of the lifting platform 302, which is adjusted by the lifting assembly, the test tube can be locked in place, thereby performing cell injection.

[0049] Please refer to the above embodiments for further details. Figure 2The fitting hole on the top of the lifting platform 302 matches the rolled edge of the test tube, and the fitting hole is larger than the outer diameter of the test tube. By making the fitting hole larger than the outer diameter of the test tube, it is easier to insert the test tube. The fitting hole matches the rolled edge of the test tube, which makes it easier for the lifting platform 302 to lift the test tube.

[0050] Please refer to the above embodiments for further details. Figure 1 The injection machine 1 is equipped with a cassette cell injection device 2, which is used to inject cells into cassette culture dishes. By installing the cassette cell injection device 2 inside the injection machine 1, the injection machine 1 can inject cells into both test tubes and cassette culture dishes.

[0051] Example 2: Please refer to Figure 1 and Figure 3 - Figure 12 The system includes an injection machine 1, which contains a tubular cell injection device, serving as a second injection device. The device includes a second support plate 5, and a cell injection assembly 4 is mounted on the side of the second support plate 5. The cell injection assembly 4 includes an injection needle, an injection system, and a control system. A movable guide platform 6 is located inside the second support plate 5. A test tube rack 10 is mounted inside the movable guide platform 6 via a linear moving module 9. The linear moving module 9 can be a guide rail structure used to move the test tube rack 10 laterally. The test tube rack 10 includes a base plate assembly 11, which includes a mounting plate 1101. Multiple test tube sleeves 1102 are mounted on the top of the mounting plate 1101. The test tube sleeves 1102 are used to hold and support test tubes. Multiple first guide rods 1103 are also mounted on the top of the mounting plate 1101. The exterior of each of the three components is fitted with a first spring 1104. Two sets of movable components 12 are symmetrically and movably installed on the exterior of multiple sets of first guide rods 1103. Each movable component 12 includes a movable frame 1201. The side of the movable frame 1201 is provided with a limit guide block 1204. Multiple sets of second guide rods 1202 are provided on the inner side of the movable frame 1201. The exterior of each set of second guide rods 1202 is fitted with a second spring 1203. A shelf assembly 13 is movably installed between the second guide rods 1202 of the two sets of movable components 12. The shelf assembly 13 is used to hold multiple sets of test tubes. The shelf assembly 13 includes a mounting frame 1301. The top of the mounting frame 1301 is provided with a fitting hole for holding the test tubes. The bottom of the mounting frame 1301 is provided with a round hole 1302 that matches the test tube sleeve 1102. An extension frame 1303 is provided at the bottom of the mounting frame 1301.

[0052] The inner side of the movable guide table 6 is provided with a limiting guide rail 7, which is used to adjust the height of the limiting guide block 1204, thereby adjusting the height of the movable component 12 and the shelf component 13 of the test tube rack 10. The side of the second support plate 5 is provided with a lifting component 8, which is used to adjust the height of the extension rack 1303, thereby adjusting the height of the shelf component 13.

[0053] Please refer to the above embodiments for further details. Figure 1 The injection machine 1 is equipped with a cassette cell injection device 2, which is used to inject cells into cassette culture dishes. By installing the cassette cell injection device 2 inside the injection machine 1, the injection machine 1 can inject cells into both test tubes and cassette culture dishes.

[0054] Please refer to the above embodiments for further details. Figure 6 and Figure 7 The top of the mounting plate 1101 has multiple through slots 1105, which match the extension frame 1303. By opening multiple through slots 1105 to avoid the extension frame 1303 of the shelf assembly 13, the extension frame 1303 can move within the through slots 1105.

[0055] Please refer to the above embodiments for further details. Figure 6 The top of the test tube sleeve 1102 is provided with a flexible material, and the top of the test tube sleeve 1102 matches the bottom of the test tube. By providing a flexible material, such as a rubber layer, on the top of the test tube sleeve 1102 to support the bottom of the test tube, it can play a certain role in stabilizing and protecting the test tube.

[0056] Please refer to the above embodiments for further details. Figure 4 and Figure 8 The limiting guide block 1204 of the movable component 12 matches the limiting guide rail 7. The limiting guide block 1204 slides inside the limiting guide rail 7. When the limiting guide block 1204 slides, the limiting guide rail 7 can change the height of the limiting guide block 1204. By setting the limiting guide rail 7, when the test tube rack 10 moves, the limiting guide block 1204 and the limiting guide rail 7 interact to increase the height of the limiting guide block 1204, thereby changing the height of the movable component 12 and the shelf assembly 13 installed on its top. In other words, the movable component 12 and the shelf assembly 13 rise to lift multiple sets of test tubes.

[0057] Please refer to the above embodiments for further details. Figure 5 The shelf assembly 13 is located in multiple sets of two sets of movable components 12, and the mounting brackets 1301 of the multiple sets of shelf assemblies 13 are all movably connected to the second guide rod 1202 of the movable component 12. By setting multiple sets of shelf assemblies 13, the test tube rack 10 can accommodate multiple sets of test tubes at the same time.

[0058] Please refer to the above embodiments for further details. Figure 9 The fitting hole on the top of the mounting bracket 1301 matches the rolled edge of the upper edge of the test tube, and the fitting hole is larger than the outer diameter of the test tube. By making the fitting hole larger than the outer wall of the test tube, it is easier to insert the test tube. Furthermore, the fitting hole matches the rolled edge of the test tube, which makes it easier for the mounting bracket 1301 to lift the test tube.

[0059] In practical operation, taking Example 1 as an example, the operator activates the lifting assembly to lower the height of the lifting platform 302 along the first support plate 301, leaving sufficient space between the lifting platform 302 and the cell injection assembly 4. Then, the operator places multiple test tubes into the fitting holes of the lifting platform 302 in sequence, using the upper end of the test tube along the rolled edge to engage with the fitting hole of the lifting platform 302. The size of the fitting hole is slightly larger than the outer wall size of the test tube, which facilitates the insertion of the test tube. However, the size of the fitting hole matches the rolled edge of the test tube, ensuring that the fitting opening of the lifting platform 302 can limit the test tube and drive it to rise, and ensuring that the center of the test tube is vertically upward. Subsequently, the operator activates the lifting assembly again to raise the lifting platform 302, allowing multiple needles of the cell injection assembly 4 to be inserted into the test tube, and then activates the cell injection assembly 4 to begin the cell injection. Similarly, after the cell injection is completed, when the operator retrieves the test tube, they lift the bottom of the test tube with their hand to remove it from the fitting hole.

[0060] Taking Example 2 as an example, the linear moving module 9 is first activated to move the test tube placement rack 10 to the loading station. At this time, the moving component 12 and the base plate component 11 are in a close fit, that is, the moving component 12 and the rack component 13 are both in a low position. That is, the fitting hole of the rack component 13 and the test tube sleeve 1102 of the base plate component 11 are close to each other. The staff puts multiple sets of test tubes into the fitting hole of the rack component 13 in sequence. When placing the test tubes, the bottom of the test tube is located in the test tube sleeve 1102, while the upper half of the test tube will be exposed on the rack component 13. At this time, since the fitting hole of the rack component 13 is distributed on the upper half of the outer wall of the test tube, the size of the fitting hole is slightly larger than the outer wall diameter of the test tube, and the test tube may tilt slightly.

[0061] When the test tube rack 10 completes the loading of test tubes, the linear movement module 9 is activated to move the test tube rack 10 to the injection station. During the movement of the test tube rack 10, the limiting guide block 1204 and the limiting guide rail 7 of the movable component 12 interact, causing the movable component 12 to slide and rise along the first guide rod 1103 and compress the first spring 1104. At the same time, the height of the two sets of movable components 12 will also drive multiple sets of shelf assemblies 13 to rise synchronously. In turn, the rise of multiple sets of shelf assemblies 13 lifts multiple sets of test tubes. That is, the fitting hole of the shelf assembly 13 lifts the test tube through the rolled edge of the upper end of the limiting test tube and helps to straighten the test tube, making its center vertically distributed. The bottom of the test tube will detach from the test tube sleeve 1102. By controlling the linear movement module 9, each set of shelf assemblies 13 is moved sequentially. The device moves directly beneath the cell injection assembly 4, and then activates the lifting assembly 8 to lift the extension frame 1303 of the shelf assembly 13 directly beneath the cell injection assembly 4. The extension frame 1303 moves and rises within the through groove 1105 of the base plate assembly 11, causing the connected mounting frame 1301 to slide and rise along the second guide rod 1202, compressing the second spring 1203. This causes multiple sets of test tubes engaged within the shelf assembly 13 to approach the cell injection assembly 4, activating the cell injection assembly 4 to perform cell injection. In the same manner, the linear movement module 9 and the lifting assembly 8 are controlled to complete the cell injection for all test tubes. After completion, the device returns to the loading station, and the moving assembly 12 and shelf assembly 13 return to their low positions, exposing multiple sets of test tubes for easy access by staff.

After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
