[0035] See also Figure 1 , Figure 1 It is a structural schematic diagram of the first embodiment of the sample tube processing device of the present application. The sample tube processing device 1 provided in the embodiment of the present application is arranged in a pipeline system, and is used to provide sample tubes for a sample analyzer and to recover sample tubes, including a rack 11 and a sample tube loading assembly 12.

[0036] The sample tube loading assembly 12 is slidably disposed on the rack 11 for loading sample tubes. The sample tube loading assembly 12 can slide relative to the rack 11 and be located inside or outside the rack 11 .

[0037] In one embodiment, the sample tube processing device 1 may further include a robotic arm assembly (not shown). When the sample tube loading assembly 12 is located inside the rack 11, the robotic arm assembly can clamp the sample tubes to be tested loaded on the sample tube loading assembly 12 to provide sample tubes for the sample analyzer, and clamp the sample tubes that have completed testing in the sample analyzer and place them on the sample tube loading assembly 12 to complete the recovery of the sample tubes.

[0038] The sample tube processing device 1 provided in the embodiment of the present application integrates sample injection and sample recovery into one, reduces the space occupied by the sample injection and sample recovery devices in the pipeline system, reduces the setup cost, improves the processing efficiency of the sample tube processing device 1, and enhances the user experience of the sample tube processing device 1.

[0039] Alternatively, as Figure 2 As shown, Figure 2 1 is a schematic structural diagram of a first embodiment of a sample tube loading assembly of the present application. The sample tube loading assembly 12 provided in the embodiment of the present application comprises a sample tube loading tray 121 and a loading tray drawer 122.

[0040] The sample tube loading tray 121 is detachably mounted on the loading tray drawer 122 for loading sample tubes. The loading tray drawer 122 is slidably mounted on the rack 11 and is configured to include a first state located inside the rack 11 and a second state located outside the rack 11 .

[0041] Specifically, when the loading tray drawer 122 is in the first state, located inside the rack 11, and the sample tube loading tray 121 placed on the loading tray drawer 122 is also located inside the rack 11, the sample tubes to be tested on the sample tube loading tray 121 can be provided to the sample analyzer to complete the sample tube injection operation. At the same time, the sample tubes that have completed testing in the sample analyzer can be placed on the sample tube loading tray 121 to complete the sample tube recovery operation.

[0042] Then, the loading tray drawer 122 switches to the second state, being located outside the rack 11, and the sample tube loading tray 121 placed on the loading tray drawer 122 is also located outside the rack. At this point, the sample tubes that have completed testing on the sample tube loading tray 121 can be unloaded and refilled with sample tubes to be tested. Since the sample tube loading tray 121 is detachably mounted on the loading tray drawer 122, the sample tube loading tray 121 loaded with the sample tubes that have completed testing can be directly removed from the loading tray drawer 122 and replaced with the sample tube loading tray 121 loaded with the sample tubes to be tested. This allows the sample tubes that have completed testing to be unloaded and the sample tubes to be tested to be refilled while the loading tray drawer 122 is in the second state.

[0043] By switching the loading tray drawer 122 between the first and second states, the sample tube injection and recovery operations can be completed. Furthermore, since the sample tube loading tray 121 is detachably mounted on the loading tray drawer 122, the sample tube loading tray 121 can be directly operated, simplifying the sample tube operation steps and further enhancing the user experience of the sample tube processing device 1.

[0044] The sample tube loading assembly 12 may include a plurality of sample tube loading trays 121 and a plurality of loading tray drawers 122 to improve the efficiency of sample tube injection and recovery in the sample tube processing device 1. Figure 1 As shown, the sample tube loading assembly 12 may include five sample tube loading trays 121 and five loading tray drawers 122. In other embodiments, the sample tube loading assembly 12 may also include other numbers of sample tube loading trays 121 and loading tray drawers 122, which may be set according to user needs, and this application does not impose any restrictions on this.

[0045] It can be understood that when the loading tray drawer 122 is switched from the second state to the first state, at least one of the multiple sample tube loading trays 121 can be in an empty state, and is used to collect sample tubes that have completed testing, and provide space for recycling and placing the sample tubes that have completed testing to complete the sample recovery operation.

[0046] Alternatively, as Figure 3 As shown, Figure 3 1 is a schematic structural diagram of a second embodiment of the sample tube loading assembly of the present application. The sample tube loading assembly 12 further includes a positioning flange 123 and a positioning pin 124.

[0047] A positioning flange 123 is provided on a side of the loading tray drawer 122 near the sample tube loading tray 121, and the positioning flange 123 and the loading tray drawer 122 form a placement area, on which the sample tube loading tray 121 is detachably placed. The size of the placement area can be equal to or slightly larger than the bottom size of the sample tube loading tray 121. Thus, when the sample tube loading tray 121 is placed on the loading tray drawer 122, the positioning flange 123 positions and roughly secures the sample tube loading tray 121, preventing the sample tube loading tray 121 from falling off the loading tray drawer 122 during the sliding process of the loading tray drawer 122 due to positional errors caused by the sample tube loading tray 121 being placed on the loading tray drawer 122. This improves the sliding safety of the loading tray drawer 122 and enhances the practicality and safety of the sample tube processing device 1.

[0048] Furthermore, a positioning pin 124 is provided on the placement area, and a groove (not shown) is provided on the side of the sample tube loading tray 121 near the loading tray drawer 122, which corresponds to the positioning pin 124. When the sample tube loading tray 121 is placed on the loading tray drawer 122, the positioning pin 124 is disposed in the groove, which can further position the sample tube loading tray 121 on the loading tray drawer 122, thereby improving the safety of the sample tube loading tray 121.

[0049] It is understandable that the positioning pin 124 can also be replaced with other protrusions, or other structures that cooperate with the sample tube loading tray 121. On the premise of achieving the effect of positioning the sample tube loading tray 121, this application does not limit the cooperating structure with the sample tube loading tray 121.

[0050] Optionally, see Figure 4 , Figure 4 1 is a schematic structural diagram of a second embodiment of the sample tube processing device of the present application. The sample tube processing device 1 further includes a sliding guide rail 13 .

[0051] The sliding rail 13 is disposed on the frame 11, and the loading tray drawer 122 is slidably disposed on the sliding rail 13. Specifically, a through slot extending along the length of the loading tray drawer 122 may be provided on the side of the loading tray drawer 122 away from the sample tube loading tray 121 (the side closer to the sliding rail 13). The loading tray drawer 122 is disposed on the sliding rail 13 via the through slot, and the loading tray drawer 122 can slide along the length of the loading tray drawer 122 on the sliding rail 13 to switch between a first state and a second state. Furthermore, because the loading tray drawer 122 is slidably connected to the sliding rail 13 via the through slot, the contact area between the loading tray drawer 122 and the sliding rail 13 is increased, thereby improving the stability of the loading tray drawer 122 sliding on the sliding rail 13.

[0052] In one embodiment, the frame 11 includes a drawer opening 14, and the first end of the sliding rail 13 is spaced away from the drawer opening 14 relative to the second end of the sliding rail 13. When the loading tray drawer 122 switches from the first state to the second state, the loading tray drawer 122 can be drawn out of the frame 11 via the second end of the loading tray drawer 122. The first end of the loading tray drawer 122 moves along the sliding rail 13 from the first end of the sliding rail 13 to the second end of the sliding rail 13, approaching the drawer opening 14. That is, when the loading tray drawer 122 is in the second state, the first end of the loading tray drawer 122 is closer to the drawer opening 14 than the second end of the loading tray drawer 122.

[0053] During the process of switching the loading tray drawer 122 from the second state to the first state, the loading tray drawer 122 can be pushed into the interior of the frame 11 through the second end of the loading tray drawer 122, and the first end of the loading tray drawer 122 will move along the sliding guide rail 13 from the second end of the sliding guide rail 13 to the first end of the sliding guide rail 13. At this time, the second end of the loading tray drawer 122 is close to the drawer opening 14. That is, when the loading tray drawer 122 is in the first state, the first end of the loading tray drawer 122 will be farther away from the drawer opening 14 than the second end of the loading tray drawer 122.

[0054] Optionally, see Figure 5 , Figure 5 This is a structural diagram of the third embodiment of the sample tube processing device of the present application. The sample tube processing device 1 also includes a positioning component 15.

[0055] The positioning assembly 15 is disposed on the frame 11 and spaced apart from the first end of the sliding guide rail 13 , and is used to detect that the loading tray drawer 122 switches to the first state and is in position.

[0056] Specifically, the in-position assembly 15 includes an in-position optical coupler 151, and the sample tube loading assembly 12 also includes an optical coupler baffle 125. The optical coupler baffle 125 is arranged at the first end of the loading tray drawer 122. When the loading tray drawer 122 switches from the second state to the first state, the optical coupler baffle 125 gradually approaches the in-position optical coupler 151 along the sliding guide rail 13 along the first end of the loading tray drawer 122. After the loading tray drawer 122 switches to the first state and is in position, the optical coupler baffle 125 will be located in the in-position optical coupler 151, blocking the in-position optical coupler. The light generated by 151 is in place, and the optical coupler 151 can respond to the loading tray drawer 122 to switch to the first state in place, thereby avoiding the loading tray drawer 122 from being pushed too much and colliding with other components in the rack 11, or the loading tray drawer 122 from being pushed into place, affecting the subsequent movement of the sample tubes in the sample tube loading tray 121 by the robotic arm components or the loading of the recovered sample tubes onto the sample tube loading tray 121, thereby improving the stability of the loading tray drawer 122 in switching to the first state and improving the stability and safety of the sample tube processing device 1.

[0057] Optionally, combine Figure 5 and Figure 6 , Figure 6 yes Figure 2 The sample tube processing device 1 further includes a first fixing member 16 and a second fixing member 17.

[0058] The first fixing member 16 is provided on the frame 11 and is spaced apart from the first end of the sliding guide rail 13. The second fixing member 17 is provided at the end portion of the first end of the loading tray drawer 122. The first fixing member 16 and the second fixing member 17 are used to fix the loading tray drawer 122 to the frame 11 when the loading tray drawer 122 is in the first state.

[0059] In one embodiment, the first fixing member 16 includes an iron sheet 161, and the second fixing member 17 includes a magnet 171. When the loading tray drawer 122 is switched to the first state, the first end of the loading tray drawer 122 moves to the first end of the sliding guide rail 13. At this time, the magnetic force generated by the magnet 171 attracts the iron sheet 161. The cooperation between the magnet 171 and the iron sheet 161 fixes the loading tray drawer 122 on the rack 11, and also positions the loading tray drawer 122 inside the rack 11, so as to prevent the loading tray drawer 122 from being driven by other components in the rack 11 and shaking relative to the rack 11, thereby improving the stability and safety of the sample tube processing device 1.

[0060] In another embodiment, the second fixing member 17 further includes a cushioning rubber pad 172, which is disposed on the magnet 171. When the loading tray drawer 122 is in the first state, the cushioning rubber pad 172 is located between the iron sheet 161 and the magnet 171. This prevents the magnet 171 from approaching the iron sheet 161 and colliding with the iron sheet 161 when the loading tray drawer 122 is switched to the first state, thereby preventing wear and tear on the iron sheet 161 and the magnet 171 or generating noise. This improves the safety of switching the loading tray drawer 122 to the first state and further enhances the user experience of the sample tube processing device 1.

[0061] Optionally, see Figure 7 , Figure 7 It is a structural schematic diagram of an embodiment of the locking assembly of the present application. The sample tube processing device 1 also includes a locking assembly 18, which is arranged on the frame 11 and the loading tray drawer 122. The locking assembly 18 is used to lock the loading tray drawer 122 on the frame 11 when the loading tray drawer 122 is in the first state.

[0062] In one embodiment, the locking assembly 18 includes a locking plate 181 and an electromagnet 182. The electromagnet 182 is disposed on the frame 11, specifically, at the drawer opening 14. The locking plate 181 is disposed at the second end of the loading tray drawer 122. When the loading tray drawer 122 is in the first state, the movable portion of the electromagnet 182 extends and is located in the fixing hole of the locking plate 181, thereby locking the loading tray drawer 122 in the first state to the frame 11.

[0063] Specifically, when the loading tray drawer 122 switches from the second state to the first state, the electromagnet 182 can be energized, and then the moving part of the electromagnet 182 extends out and is located in the fixed hole of the locking piece 181, locking the loading tray drawer 122 in the first state to the rack 11, thereby preventing the user from pulling the loading tray drawer 122 out of the rack 11 during the process of the robotic arm assembly operating the sample tubes in the sample tube loading tray 121 or other components of the sample tube processing device 1 operating the sample tubes in the sample tube loading tray 121, thereby affecting the internal operation process of the sample tube processing device 1, or even damaging other components of the sample tube processing device 1, and endangering the safety of the user, thereby improving the safety of the sample tube processing device 1.

[0064] When the loading tray drawer 122 switches from the first state to the second state, the electromagnet 182 is powered off, the moving portion of the electromagnet 182 retracts, and the loading tray drawer 122 is released. At this time, the loading tray drawer 122 can be pulled from the inside of the frame 11 to the outside of the frame 11.

[0065] In one embodiment, if Figure 7As shown, the movable portion of the electromagnet 182 is provided with an inclined surface at the end near the locking plate 181, and the inclined surface is arranged downwardly and away from the exterior of the frame 11. Therefore, when the loading tray drawer 122 is pushed to switch from the second state to the first state, the movable portion of the electromagnet 182 can be pre-extended. When the loading tray drawer 122 is about to switch to the first state, the locking plate 181 contacts the inclined surface. As the loading tray drawer 122 continues to be pushed, the locking plate 181 is guided by the inclined surface. When the loading tray drawer 122 switches to the first state, the locking plate 181 moves to the other side of the inclined surface, and the movable portion of the electromagnet 182 is located in the fixing hole of the locking plate 181, locking the loading tray drawer 122. At this time, the contact state between the locking plate 181 and the movable portion can be used to determine whether the loading tray drawer 122 has switched to the first state. When the locking plate 181 moves to the other side of the inclined surface and the movable portion is located in the fixing hole of the locking plate 181, it is determined that the loading tray drawer 122 has switched to the first state.

[0066] In summary, the sample tube processing device 1 provided in the embodiment of the present application integrates sample injection and sample recovery into one, reduces the space occupied by the devices for sample injection and sample recovery in the pipeline system, reduces the setup cost, improves the processing efficiency of the sample tube processing device 1, and enhances the user experience of the sample tube processing device 1.

[0067] At the same time, by sliding the sample tube loading component 12 inside and outside the rack 11, the sample tube sampling and recovery operations are simplified, and by setting the positioning component 15, the loading tray drawer 122 is switched to the first state in place to determine, and by setting the first fixing member 16, the second fixing member 17 and the locking component 18, etc., the loading tray drawer 122 is fixed on the rack 11, thereby improving the stability and safety of the sample tube processing device 1, and further enhancing the user's experience of the sample tube processing device 1.

[0068] The present application also provides a pipeline system, including a sample analyzer and a sample tube processing device 1. The sample tube processing device 1 is spaced apart from the sample analyzer and is used to provide sample tubes for sample testing by the sample analyzer or to recover sample tubes that have completed sample testing at the sample analyzer.
