[0002] Flow cytometry is a core tool for high-throughput analysis of single cells or biological particles using laser excitation and photoelectric detection technologies. Its core function is to achieve multi-dimensional analysis of cell phenotype, function, and molecular characteristics. The core functional modules of a flow cytometer include four major systems: laser excitation, optical detection, fluid flow control, and data processing. Traditional single-laser multi-channel optical detection systems, i.e., signal acquisition modules, use multiple optical systems with different wavelengths to simultaneously acquire excitation fluorescence at various wavelengths. Furthermore, the filters corresponding to each optical system are different, and the corresponding filters need to be replaced when the acquired wavelength changes. Replacing traditional filters requires disassembling the flow cytometer signal receiving device and the mounting bracket for the filters, making filter replacement cumbersome and inconvenient.

[0033] This utility model provides a filter replacement tool 3, which is suitable for picking up and putting in a filter holder. By removing the filter holder from the flow cytometer signal receiving device 100, the filter set on the filter holder can be maintained or replaced. Specifically, in conjunction with Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the filter replacement tool 3 includes a tool body 31 and at least two clamping parts 32 disposed on the tool body 31, wherein the dimensions of each clamping part 32 are different.

[0034] In this embodiment, the tool body 31 can be held by a user's hand or clamped by a robotic arm, allowing the entire filter replacement tool 3 to be moved by holding the tool body 31. The clamping part 32 can be used to clamp the filter holder, making it easy to remove the filter holder from the flow cell signal receiving device 100 for maintenance and replacement of the filter set on the filter holder; moreover, at least two of the clamping parts 32 are configured with different sizes, so that each clamping part 32 can be used to clamp filter holders of different sizes to replace different types or sizes of filters, making filter replacement simpler and more convenient. The filter replacement tool 3 is applicable to the replacement of various filters, with a wider range of applications and convenient operation.

[0035] The shape and size of the tool body 31 are not specifically limited. The tool body 31 can be block-shaped, sheet-shaped, or strip-shaped, and its cross-section can be circular, triangular, or polygonal. Preferably, the tool body 31 is flat and square, having both length and width directions. The flat shape of the tool body 31 occupies less space and is easier to store.

[0036] The number of clamping parts 32 can be two or more, so that the number of clamping parts 32 can be reasonably adjusted according to the number of filter holders on the corresponding flow cytometer signal receiving device 100, so that one filter replacement tool 3 can solve the replacement problem of multiple filter holders, without the need to set up multiple tools, which saves more space and also saves more cost.

[0037] In one embodiment, at least two clamping portions 32 are located on the same side of the tool body 31, and the at least two clamping portions 32 can be arranged at intervals along the length or width direction of the tool body 31. Wherein, if multiple clamping portions 32 in the same row are identical, multiple clamping portions 32 can simultaneously clamp onto multiple filter holders in the same row, thereby allowing for the simultaneous handling of multiple filter holders, saving time. If multiple clamping portions 32 are not identical, different filter holders can be handled one by one.

[0038] In another embodiment, such as Figure 1 and Figure 2 As shown, at least two of the clamping parts 32 may be located on different sides of the tool body 31. When using one of the clamping parts 32, interference from the other clamping part 32 can be avoided, and different filter holders can be picked up better.

[0039] It is understood that the clamping part 32 can be configured in various ways. In one embodiment, the clamping part 32 can be configured as a finger cylinder for picking up and putting down the filter holder; or, the clamping part 32 can be configured as a mechanical claw.

[0040] Preferably, each clamping part 32 includes two clamping arms 321 arranged opposite to each other, which clamp the filter holder on opposite sides, thereby enabling the pick-up of the filter holder. Furthermore, the distance between the two clamping arms 321 of the plurality of clamping parts 32 is different, allowing for the provision of corresponding two clamping arms 321 for different filter holders. This results in better compatibility and higher efficiency in picking up and placing the filter holder by using different clamping parts 32 to hold different filter holders.

[0041] Furthermore, combined Figure 3 and Figure 4 As shown, each of the clamping arms 321 has a connecting end and a free end arranged opposite to each other. The connecting end is connected to the tool body 31. The free end of each clamping arm 321 is provided with a buckle 322. The buckles 322 of the two clamping arms 321 extend toward each other and abut against the second step of the filter holder through the two buckles 322. Thus, when lifted upward, the filter holder can be dislodged from the mounting groove of the self-flowing cell instrument signal receiving device 100, making the effect on the filter holder more stable.

[0042] In another embodiment, each of the clamping portions 32 may include a plurality of clamping arms 321 arranged in a ring shape, with an entrance on one side. Each clamping portion 32 is adapted to engage with the end of the filter holder from the entrance. This ensures that the filter holder is abutted against by the clamping arms 321 on at least three sides, making it more stable and less likely to fall when the filter holder is picked up.

[0043] The clamping parts 32 are arranged at intervals along the same direction on the tool body 31 in a row or array pattern. This arrangement is suitable for situations with a large number of filter holders, allowing for simultaneous pickup of multiple filter holders with higher efficiency. Alternatively, the clamping parts 32 can be located on opposite sides of the tool body 31, allowing for pickup of different filter holders by switching between different directions. This improves the pickup efficiency of individual filter holders without affecting other filter holders. Furthermore, the clamping parts 32 can be arranged circumferentially along the tool body 31. When there are many types of filter holders, more clamping parts 32 of various sizes can be provided, resulting in a wider range of applications and better adaptability.

[0044] Preferably, there are two clamping parts 32, which are respectively located at both ends of the tool body 31 along the length direction. This makes the filter replacement tool 3 smaller in size and applicable to the replacement operation of two types of filter holders, making the filter replacement tool 3 easier to store and more versatile.

[0045] This utility model also provides a flow cytometer signal receiving device 100, combined with... Figure 1 and Figure 3 As shown, the flow cytometer signal receiving device 100 includes a housing 1, an optical component 2, and the aforementioned filter replacement tool. The optical component 2 is disposed within the housing 1 and includes a mounting groove, a first optical support 22 and a second optical support 23 disposed within the mounting groove, a first lens 24 disposed on the first optical support 22, and a second lens 25 disposed on the second optical support 23. At least a portion of the first optical support 22 and at least a portion of the second optical support 23 protrude from the mounting groove. The filter replacement tool 3 is detachably disposed within or outside the housing 1 and is used to engage with the portion of the first optical support 22 or the second optical support 23 protruding from the mounting groove to remove the first optical support 22 or the second optical support 23 from the mounting groove. This invention improves the applicability of the flow cytometer signal receiving device 100, makes filter replacement more convenient, and thus increases work efficiency.

[0046] Both the first optical bracket 22 and the second optical bracket 23 have a first stepped portion and a second stepped portion. The first stepped portion abuts against the opening of the mounting groove, thereby limiting the positioning of the first optical bracket 22 and the second optical bracket 23. The filter replacement tool 3 is used to engage with the second stepped portion. Specifically, the two clamping arms 321 of the filter replacement tool 3 are respectively clamped on both sides of the second stepped portion, and the two fasteners 322 are fastened to the second stepped portion, so as to better remove the first optical bracket 22 or the second optical bracket 23 from the corresponding mounting groove.

[0047] Furthermore, the outer casing 1 includes a casing body 11 and a cover plate 12 disposed on the casing body 11. The casing body 11 is box-shaped and has an upward-facing opening. The cover plate 12 is slidably disposed at the opening to close or open the opening. When the cover plate 12 is in the open state, both the first optical support 22 and the second optical support 23 are exposed, making it easier to replace the filter using the filter replacement tool 3. Moreover, the cover plate 12 is slidably disposed on the casing body 11, making opening and closing more convenient.

[0048] The optical component 2 includes an optical mounting base 21, which comprises a first base 211, a second base 212, and a partition plate 213. The first base 211 and the second base 212 are detachably connected. The first base 211 has a first semi-groove, and the second base 212 has a second semi-groove opposite to the first semi-groove. Both the first base 211 and the second base 212 are approximately U-shaped, with the open sides of the first base 211 and the second base 212 facing each other. The partition plate 213 is disposed between the first base 211 and the second base 212, and its two sides respectively block the open sides of the first and second semi-grooves to form the two accommodating cavities mentioned above. Each accommodating cavity has a plurality of partition protrusions on its sidewall, and the space between each pair of adjacent partition protrusions forms a mounting groove. The optical mounting base 21 is designed as a split structure, which facilitates the processing of the first base 211, the second base 212 and the partition plate 213, and also facilitates the maintenance of the first base 211, the second base 212 and the partition plate 213, resulting in lower maintenance costs.

[0049] Furthermore, a first mounting groove 2111 is formed between the first base 211 and the partition plate 213, and a second mounting groove 2121 is formed between the second base 212 and the partition plate 213. Multiple first lenses 24 and multiple second lenses 25 are provided, with each first lens 24 corresponding to one of the multiple first mounting grooves 2111 and each second lens 25 corresponding to one of the multiple second mounting grooves 2121. The first filter can reflect and transmit light. A portion of the light is reflected to the corresponding second filter and then transmitted to the detection component after being filtered by the second filter. Another portion of the light passes through the first filter and is transmitted to the next first filter, thus reflecting and transmitting light of different wavelengths. Therefore, multiple different wavelengths of excitation fluorescence are obtained through the multiple first filters and multiple second filters.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
