[0036] The following detailed description of the present disclosure is for purposes of illustration only and is in no way a limitation of the present disclosure, its application or uses. The embodiments described in this specification are not exhaustive and are merely some of multiple possible embodiments. The exemplary embodiments may be implemented in many different forms, and should not be construed as limiting the scope of the present disclosure. In some exemplary embodiments, well-known processes, well-known device structures, and well-known technologies may not be described in detail.
[0037] The signal switching device according to the present disclosure is suitable for various sample analyzers that include an optical detection system. For example, the sample analyzers are configured to detect or sort liquid samples containing biological particles (e.g., extracellular vesicles) or non-biological particles (e.g., beads) .
[0038] A signal switching device 100 according to a first embodiment of the present disclosure will be described below with reference to Figs. 1 to 2. In several accompanying drawings, like reference numerals indicate like components and / or assemblies.
[0039] Fig. 1 is a schematic view of a sample analyzer 10; and Fig. 2 is a schematic view of the signal switching device 100 according to the first embodiment of the present disclosure.
[0040] As shown in Fig. 1, the sample analyzer 10 includes an optical bench 11 and a Cyto WDM module 12. The optical bench 11 and the Cyto WDM module 12 are connected to each other by a second fiber 13, and the optical bench 11 transmits optical signals to the Cyto WDM module 12 via the second fiber 13.
[0041] As shown in Fig. 2, the signal switching device 100 includes a first fiber 110 and a tunnel 120 disposed on the sample analyzer 10. The first fiber 110 may be led out of the sample analyzer 10 through the tunnel 120.
[0042] As shown in Fig. 2, a BOSS WDM module 20 is a separate module independent of the sample analyzer 10, and the BOSS WDM module 20 is provided with a first fiber interface 21 for connecting to the first fiber 110. The signal switching device 100 may switch the optical signals output from the optical bench 11 between the Cyto WDM module 12 of the sample analyzer 10 and the BOSS WDM module 20.
[0043] Specifically, the signal switching device 100 according to this embodiment utilizes the first fiber 110 to replace the original second fiber 13 of the sample analyzer 10, and the first fiber 110 may pass out of the sample analyzer 10 from the tunnel 120. The first fiber 110 is longer than the original second fiber 13, so that the first fiber 110 may be connected to the BOSS WDM module 20 located outside the sample analyzer 10.
[0044] In this embodiment, the tunnel 120 is located in a rear panel of the sample analyzer 10.
[0045] When the BOSS WDM module 20 is needed, the first fiber 110 is pulled out from a second fiber interface 14 of the Cyto WDM module 12, and subsequently the first fiber 110 passes through the tunnel 120 and is then inserted into the first fiber interface 21 of the BOSS WDM module 20. When the Cyto WDM module 12 is needed, the first fiber 110 is pulled out from the first fiber interface 21 of the BOSS WDM module 20, and subsequently the first fiber 110 passes through the tunnel 120 and enters into the sample analyzer 10. The first fiber 110 is then curled until its length is suitable to connect the optical bench 11 and the Cyto WDM module 12. Finally the first fiber 110 is inserted into the second fiber interface 14 of the Cyto WDM module 12.
[0046] The signal switching device 100 according to this embodiment has a simple structure and a low cost.
[0047] A signal switching device 200 according to a second embodiment of the present disclosure will be described below with reference to Fig. 3. In Fig. 3, like reference numerals as above indicate like components and / or assemblies.
[0048] Fig. 3 is a schematic view of the signal switching device 200 according to the second embodiment of the present disclosure.
[0049] As shown in Fig. 3, the signal switching device 200 includes a third fiber 210 and a docker 220. The docker 220 is mounted on the sample analyzer 10, and preferably, the docker 220 is mounted on the rear panel of the sample analyzer 10. The docker 220 has an input port located inside the sample analyzer 10 and an output port located outside the sample analyzer 10.
[0050] As shown in Fig. 3, one end of the third fiber 210 is connected to the first fiber interface 21 of the BOSS WDM module 20, and the other end is connected to the output port of the docker 220.
[0051] When the BOSS WDM module 20 is needed, the second fiber 13 located within the sample analyzer 10 is pulled out from the second fiber interface 14 of the Cyto WDM module 12 and inserted into the input port of the docker 220, thereby the optical bench 11 and the BOSS WDM module 20 are connected to each other via the second fiber 13, the docker 220 and the third fiber 210. When the Cyto WDM module 12 is needed, the second fiber 13 is pulled out from the docker 220 and inserted into the second fiber interface 14 of the Cyto WDM module 12, thereby the optical bench 11 is connected to the Cyto WDM module 12 and the optical bench 11 is disconnected from the BOSS WDM module 20.
[0052] The signal switching device 200 disclosed in this embodiment has a simple structure and is simpler to operate as compared to the signal switching device 100 by avoiding curling of the longer first fiber 110.
[0053] A signal switching device 300 according to a third embodiment of the present disclosure will be described below with reference to Figs. 4 to 15. In Figs. 4-15, like reference numerals as above indicate like components and / or assemblies.
[0054] Fig. 4 is a schematic view of the signal switching device 300 according to the third embodiment of the present disclosure; Figs. 5-6 are respectively a schematic perspective view and a schematic exploded view of an optical switch; Figs. 7-11 are schematic structural views of different components of an optical switch; and Figs. 12-15 are schematic views of the optical switch in different operating positions.
[0055] As shown in Fig. 4, the signal switching device 300 includes the optical switch 30, a fourth fiber 310, a fifth fiber 320 and a sixth fiber 330. The optical switch 30 is connected to the optical bench 11 via the fourth fiber 310, the fifth fiber 320 connects the optical switch 30 and the Cyto WDM module 12, and the sixth fiber 330 connects the optical switch 30 and the BOSS WDM module 20. The optical signals entering the optical switch 30 from the optical bench 11 via the fourth fiber 310 may be switched by the optical switch 30 and then enter the Cyto WDM module 12 or the BOSS WDM module 20.
[0056] Specifically, as shown in Fig. 5, the optical switch 30 includes an input interface 31, a first output interface 32 and a second output interface 33. The fourth fiber 310 connects the optical bench 11 and the input interface 31 of the optical switch 30, the fifth fiber 320 connects the first output interface 32 of the optical switch 30 and the Cyto WDM module 12, and the sixth fiber 330 connects the second output interface 33 of the optical switch 30 and the BOSS WDM module 20. The optical switch 30 may switch the output signals between the first output interface 32 and the second output interface 33, so that the optical signals emitted from the optical bench 11 may enter the optical switch 30 via the fourth fiber 310, and then may be switched by the optical switch 30 and subsequently enter the Cyto WDM module 12 via the first output interface 32 and the fifth fiber 320 or enter the BOSS WDM module 20 via the second output interface 33 and the sixth fiber 330.
[0057] As shown in Figs. 5 and 6, the optical switch 30 further includes a body cover 40 and a body base 50, which together with a body end cover 80 which will be described in detail below form the main body of the optical switch 30 and provide a mounting foundation for other parts of the optical switch 30.
[0058] As shown in Fig. 7, the body cover 40 includes a first side plate 41, a second side plate 42 and a third side plate 43, wherein the first side plate 41 and the third side plate 43 are parallel to each other, and the second side plate 42 is perpendicular to the first side plate 41 and the third side plate 43. The first side plate 41, the second side plate 42 and the third side plate 43 are respectively provided with multiple first through holes 401, second through holes 402 and third through holes 403 along the length direction of the body cover 40 (the left -right direction in Fig. 7) . Each of the first through holes 401 corresponds to one inlet of the input interface 31, each of the second through holes 402 corresponds to one outlet of the first output interface 32, and each of the third through holes 403 corresponds to one outlet of the second output interface 33. The positions of the input interface 31, the first output interface 32 and the second output interface 33 in the length direction of the body cover 40 are corresponded to each other, so that the optical signals enter the input interface 31 may exit along the corresponding first output interface 32 or second output interface 33.
[0059] Further, the body cover 40 further includes a first positioning block 44, wherein the first positioning block 44 is connected to the first side plate 41 and the second side plate 42 and extends along the length of the body cover 40, so that the length of the first positioning block 44 is the same as that of the first side plate 41 and / or the second side plate 42. The first through holes 401 and the second through holes 402 extend through the first positioning block 44, as shown in Figs. 13 and 15. The first positioning block 44 includes a first surface 441, and the first surface 441 is oriented towards an inner hollow portion of the body cover 40 and positioned at an angle with the first side plate 41 and / or the second side plate 42.
[0060] In this embodiment, the angle “a” between the first surface 441 and the second side plate 42 is 45°.
[0061] Further, as shown in Fig. 8, the body base 50 includes a bottom base 51 and a second positioning block 52, and the body base 50 is connected to the body cover 40 via the bottom base 51.
[0062] For example, as shown in Figs. 5 and 6, the body base 50 is connected to the first side plate 41 and the third side plate 43 of the body cover 40 by bolts respectively.
[0063] Further, as shown in Fig. 8, the second positioning block 52 includes a second surface 521 and a vertical third surface 522, and the second surface 521 is positioned parallel to the first surface 441. The third surface 522 abuts against an inner surface of the third side plate 43 after the body base 50 and the body cover 40 are connected to each other, as shown in Figs. 13 and 15.
[0064] Further, as shown in Fig. 8, the second positioning block 52 is provided with multiple first through grooves 53 that connect the second surface 521 and the third surface 522. The positions of the first through holes 53 correspond to the positions of the first through holes 401 and the third through holes 403, so that the optical signals entering the optical switch 30 via the first through holes 401 may pass through the first through grooves 53 and then exit from the second output interface 33 via the third through holes 403.
[0065] Further, in order to enable the optical signals entering the input interface 31 to exit from the second output interface 33, as shown in Fig. 6, the optical switch 30 in this embodiment further includes a mirror assembly 60 and a mirror substrate 70. The mirror substrate 70 is positioned along the first surface 441, and the mirror assembly 60 is positioned along the second surface 521, so that the mirror assembly 60 and the mirror substrate 70 are parallel to each other.
[0066] Further, as shown in Fig. 8, the second positioning block 52 is provided with multiple elastic members 54 on the second surface 521, and the elastic force of the elastic members 54 causes the mirror assembly 60 to closely fit with the mirror substrate 70.
[0067] In a preferred embodiment of the present disclosure, the elastic members 54 are ball head spring plungers, and the ball head spring plungers abut against the mirror assembly 60 positioned along the second surface 521, so that the mirror assembly 60 closely fits with the mirror substrate 70.
[0068] Further, as shown in Fig. 9, the mirror substrate 70 is provided with multiple second through grooves 71, and the second through grooves 71 are positioned such that the positions of the second through grooves 71 are aligned with the positions of the first through holes 401, the first through grooves 53, and the second through holes 402 when the mirror substrate 70 is mounted between the body cover 40 and the body base 50, so that the optical signals entering the optical switch 30 may pass through the first through holes 401, the second through grooves 71, the first through grooves 53 and the second through holes 402 in turn and enter the second output interface 33.
[0069] Further, as shown in Fig. 10, the mirror assembly 60 includes a mirror body 61 and mounting portions 62, and two mounting portions 62 are symmetrically provided at both ends of the mirror body 61 in the length direction, respectively. Each of the mounting portions 62 includes a clamping portion 621, a connecting portion 622 and a handle cover 623. Two clamping portions 621 are respectively clamped at both ends of the mirror body 61 in the length direction. The clamping portion 621 is fixed to the mirror body 61, for example, by adhesion. One end of the connecting portion 622 is connected to the clamping portion 621, and the other end of the connecting portion 622 is connected to the handle cover 623. The handle cover 623 is mounted on the body end cover 80. The structures of the body end cover 80 and the handle cover 623 will be described in detail below.
[0070] As shown in Figs. 5 and 6, each of the two ends of the body cover 40 in the length direction is provided with a body end cover 80, and each end of the body cover 40 is closed by the body end cover 80. The body end cover 80 is connected to the body cover 40 by bolts, for example.
[0071] As shown in Fig. 11, the body end cover 80 is provided with a first groove 81 from the inner side (the side facing the body cover 40) to the outer side (the side away from the body cover 40) , and the body end cover 80 is provided with a second groove 82 from the outer side to the inner side. The first groove 81 and the second groove 82 are concentrically provided and pass through the thickness direction of the body end cover 80 together for guiding the movement of the handle cover 623 of the mirror assembly 60.
[0072] Specifically, as shown in Fig. 6, the handle cover 623 is mounted on an outer side surface of the body end cover 80, and the handle cover 623 is provided with a blind hole 624, the cross-sectional shape of which is matched with that of the connecting portion 622. The connecting portion 622 may extend out of the body end cover 80 from the first groove 81 and the second groove 82 of the body end cover 80 and be inserted into the blind hole 624 of the handle cover 623, so that the mirror body 61 may move up and down along the second surface 521, driven by the handle cover 623.
[0073] Further, the first groove 81 and the second groove 82 are dimensioned such that the connecting portion 622 may extend out from the first groove 81 and the second groove 82 to connect with the handle cover 623, while the clamping portion 621 may enter into the first groove 81 but not into the second groove 82.
[0074] Further, the length directions of the first groove 81 and the second groove 82 are parallel to the second surface 521, so that the movement of the mounting portions 62 along the first groove 81 and the second groove 82 may drive the mirror body 61 to move along the second surface 521.
[0075] In this embodiment, when the second output interface 33 is needed, the handle cover 623 of the mirror assembly 60 is located at a first position as shown in Fig. 12. At this position, the mirror body 61 is not located in optical paths, so that the optical signals entering the optical switch 30 pass through the first through holes 401, the second through grooves 71, the first through grooves 53 and the second through holes 402 and then reache the second output interface 33, as shown by the arrow in Fig. 13. When the first output interface 32 is needed, the handle cover 623 is slid to be moved obliquely upward along the first groove 81 and the second groove 82, driving the mirror body 61 to move obliquely upward along the second surface 521 until the handle cover 623 is located at a second position as shown in Fig. 14. At this position, the mirror body 61 is located in the optical paths, and the optical signals reaches the mirror body 61 after passing through the first through holes 401 and the second through grooves 71. After being reflected by the mirror body 61, the optical signals changes their routes to reach the first output interface 32 through the second through holes 402, as shown by the arrow in Fig. 15.
[0076] As shown in Fig. 8, since the second positioning block 52 is provided with multiple elastic members 54 on the second surface 521, the elastic force of the elastic members 54 causes the mirror assembly 60 to closely fit with the mirror substrate 70 to generate static friction. So when the handle cover 623 drives the mirror body 61 to move to the second position, it may be held in the second position against the effect of gravity.
[0077] The signal switching device 300 according to this embodiment may switch the optical paths by sliding of the handle cover 623, so that the plugging and unplugging of fibers is avoided and the operation is simple.
[0078] Although three embodiments of the signal switching device according to the present disclosure have been described above with reference to Figs. 1 to 15, it should be understood that the signal switching device according to the present disclosure should not be limited to the specific examples shown in the accompanying drawings, but may be varied as desired. For example, the signal switching device may add additional components as desired. For example, fiber holders are added to hold fibers located outside the sample analyzer 10. In addition, the signal switching device disclosed in the present disclosure is not limited to switch optical signals between the sample analyzer and the BOSS WDM, but also may switch optical signals between other different devices.
[0079] Although the present disclosure has been described with reference to exemplary embodiments, it should be understood that the present disclosure is not limited to the specific embodiments described and illustrated herein. Without departing from the scope defined by the claims, those skilled in the art may make various changes to the exemplary embodiments.
