[0045] The embodiments of the present application will be specifically described below with reference to the drawings.

[0046] Refer to Figures 1-4 As shown, in some embodiments of the present application, the present application provides a multi-functional sample detection device, including at least two sample transfer mechanisms. The sample transfer mechanism includes: an inflow track 21, an intermediate conversion track 22, an outflow track 23, a first track conversion unit 24, a commutation unit 25 and a second track conversion unit 26. The inflow tracks 21 and the outflow tracks 23 in at least two sample transfer mechanisms are connected in one-to-one correspondence, that is, the inflow tracks 21 in multiple sample transfer mechanisms are connected, and the outflow tracks 23 in multiple sample transfer mechanisms are connected. The transmission directions of the inflow track 21 and the outflow track 23 are opposite.

[0047] In this solution, the inflow track 21 and the outflow track 23 are arranged in parallel, and the intermediate conversion track 22 is located between the inflow track 21 and the outflow track 23, so that the inflow track 21, the intermediate conversion track 22 and the outflow track 23 are all arranged in parallel. The transmission direction of the intermediate conversion track 22 is the same as that of the outflow track 23. A detection function station is arranged above the outflow track 23. Specifically, the detection function station at least includes a first detection function station 11 and a second detection function station 12 arranged in sequence along the transmission direction of the outflow track 23. The outflow track 23 includes a second conveyor belt 231, and function components consistent with the number of detection function stations are arranged on one side of the second conveyor belt 231. The function components are arranged corresponding to the detection function stations, and the function components perform different detection processes at the corresponding detection function stations.

[0048] The first transfer unit 24 is disposed between the inflow track 21 and the intermediate conversion track 22, and the first transfer unit 24 is used to transfer the sample from the first transfer unit 24 to the intermediate conversion track 22. The carrier 31 on the inflow track 21 is transferred to the intermediate conversion track 22 via the first transfer unit 24.

[0049] The commutation unit 25 and the second transfer unit 26 are both located between the intermediate conversion track 22 and the outflow track 23, and the commutation unit 25 and the second transfer unit 26 are used to transfer the sample between the intermediate conversion track 22 and the outflow track 23. On the one hand, the commutation unit 25 can transfer the carrier 31 on the intermediate conversion track 22 to the outflow track 23 or transfer the carrier 31 on the outflow track 23 to the intermediate conversion track 22; on the other hand, the second transfer unit 26 can transfer the carrier 31 on the intermediate conversion track 22 to the outflow track 23. The flow terminal of the commutation unit 25 on the outflow track 23 is located at the upstream end of the detection function station, and the flow terminal of the second transfer unit 26 on the outflow track 23 is located at the downstream end of the detection function station, so that the commutation unit 25 and the second transfer unit 26 are arranged on both sides of the detection function station. The commutation unit 25 can control the sample to be transferred directly below the detection function station or to the second transfer unit 26. The sample is placed in the test tube 32 loaded on the carrier 31. The first transfer unit 24, the commutation unit 25 and the second transfer unit 26 actually drive the carrier 31, the test tube 32 and the sample to be transferred together.

[0050] Among them, the flow start end of the commutation unit 25 on the intermediate conversion track 22 is located downstream of the flow terminal of the first transfer unit 24 on the intermediate conversion track 22. The carrier 31 flows on the inflow track 21, the intermediate conversion track 22 and the outflow track 23, and uses the commutation unit 25, the second transfer unit 26 and the intermediate conversion track 22, so that the carrier 31 can approach the second detection function station 12 after passing over the first detection function station 11, so that according to the user's needs, the sample flows into the corresponding detection function station for corresponding detection procedures. Compared with the existing pipeline structure, for some functional components with longer detection procedures, if the sample in the test tube 32 does not need to undergo the corresponding detection procedure, in this solution, the carrier 31 loaded with the test tube 32 passes over some detection function stations, reducing the waiting time in front of the corresponding detection function stations, improving the detection efficiency of the sample, and at the same time reducing the accumulation in front of these detection function stations and reducing the risk of blockage.

[0051] In some embodiments of the present application, the inflow track 21 includes a first conveyor belt 211. A first track-switching unit 24 and a first identification module 212 are installed on one side of the first conveyor belt 211 relative to the intermediate conversion track 22. The first track-switching unit 24 is electrically connected to the driving module 241; the first track-switching unit 24 and the first identification module 212 are arranged in sequence along the transmission direction of the inflow track 21.

[0052] The first track-switching unit 24 includes a driving module 241 and a baffle 242. The baffle 242 is installed on the power output end of the driving module 241. Driven by the driving module 241, the baffle 242 can move to the moving path of the vehicle 31 on the inflow track 21.

[0053] The first identification module 212 is used to identify the test tube 32 on the vehicle 31 to determine whether the detection process required for the sample in the test tube 32 is downstream of the detection function station corresponding to the first track-switching unit 24. If all the required detection processes are downstream of the detection function station corresponding to the first track-switching unit 24, the first identification module 212 controls the driving module 241 to drive the baffle 242, so that the baffle 242 blocks the first conveyor belt 211, forcing the vehicle 31 to flow to the intermediate conversion track 22. If there is a detection process that is upstream of the detection function station corresponding to the first track-switching unit 24, the vehicle 31 continues to move along the inflow track 21.

[0054] Further, an avoidance groove is provided on the side of the inflow track 21 close to the intermediate conversion track 22. The vehicle 31 on the inflow track 21 is transferred to the intermediate conversion track 22 through the avoidance groove. The avoidance groove is provided corresponding to the first track-switching unit 24. Driven by the driving module 241, the baffle 242 can move to be connected to the avoidance groove.

[0055] To facilitate the transfer of the vehicle 31 between the inflow track 21 and the intermediate conversion track 22, a track-switching conveyor belt 213 is provided at the bottom of the avoidance groove. The track-switching conveyor belt 213 drives the vehicle 31 to move in a direction perpendicular to the transmission direction of the inflow track 21. The vehicle 31 flows into the avoidance groove, and the track-switching conveyor belt 213 drives the vehicle 31 to transfer towards the intermediate conversion track 22.

[0056] At the same time, an avoidance groove corresponding to the second track-switching unit 26 is provided on the side of the outflow track 23 close to the intermediate conversion track 22. A track-switching conveyor belt 213 is provided at the bottom of the avoidance groove. The vehicle 31 in the intermediate conversion track 22 is transferred to the outflow track 23 through the track-switching conveyor belt 213;

[0057] Furthermore, the track-switching conveyor belts 213 in the two avoidance grooves are driven by the same driving unit, simplifying the structure of the track-switching conveyor belt 213.

[0058] In some embodiments of the present application, Figures 2-3 As shown, the reversing unit 25 can transfer the carrier 31 on the intermediate transfer track 22 to the outflow track 23 or transfer the carrier 31 on the outflow track 23 to the intermediate transfer track 22. Specifically, the reversing unit 25 includes a circular stop block and a driver, and the stop block is located on the flow path of the carrier 31 of the intermediate transfer track 22 and the outflow track 23. A clearance groove for accommodating the carrier 31 is provided on the stop block, and the clearance groove extends to the side of the stop block to form an opening, and the carrier 31 can enter the clearance groove from the opening.

[0059] In this solution, the carrier 31 is installed on the stop block. When the driver rotates, the stop block drives the carrier 31 to rotate out of the track 23 or the intermediate conversion track 22. Since the carrier 31 is located in the yield groove, the carrier 31 can pass through the obstruction of the stop block.

[0060] More specifically, the carrier 31 is circular, the inner wall of the clearance groove is in the shape of a major arc, and the width of the opening is not less than the diameter of the carrier 31. The major arc is an arc larger than a semicircle, and after the carrier 31 enters the clearance groove, the clearance groove can also limit the carrier 31 from escaping from the clearance groove, and after the carrier 31 can pass through the stop block, it is driven by the conveyor belt of the outflow track 23 or the intermediate conversion track 22, and the carrier 31 escapes from the clearance groove.

[0061] Furthermore, a second identification module 232 is installed on the outflow track 23, the second identification module 232 is electrically connected to the driver, and the second identification module 232 is arranged corresponding to the clearance groove of the stop block, and the second identification module 232 is used to identify the test tube 32 loaded on the carrier 31. Specifically, the second identification module 232 is a barcode scanner, and the scanning light of the barcode scanner passes above the clearance groove of the stop block. The carrier 31 is installed in the clearance groove, and the barcode scanner scans the test tube 32 loaded on the carrier 31. An information code is attached to the test tube 32, and it is determined whether the sample in the test tube 32 needs to perform the detection process of the nearest detection component according to the information on the information code. Among them, the nearest detection component is the detection component closest to the downstream of the corresponding second identification module 232 in the transmission direction of the outflow track 23.

[0062] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific implementations. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be understood to be within the scope of protection of the present application.
