[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] The following is for reference. Figures 1 to 3 This invention describes the sample testing device.

[0021] This utility model provides a sample detection device, including: The main body of the chassis 100 has a sample detection chamber 101 and a sample placement chamber 102, a consumable placement chamber 103 and a waste collection chamber 104, all of which are connected to the sample detection chamber 101. The sample detection chamber 101 is equipped with a sample detection assembly. The sample placement chamber 102 and the consumable placement chamber 103 are respectively provided with a sample placement port and a first consumable placement port. The waste collection chamber 104 is provided with a waste collection port. The box cover assembly includes a first box cover 201 covering the sample placement opening, a second box cover 202 covering the first consumable placement opening, and a third box cover 203 covering the waste collection opening. The robotic arm assembly is located in the inner cavity of the chassis and is used to transfer the testing consumables in the consumables placement chamber 103 to the sample testing chamber 101, the samples in the sample tube to the testing consumables, and the testing consumables in the sample testing chamber 101 to the waste collection chamber 104.

[0022] When using the aforementioned sample testing equipment, the inner cavity of the main body 100 is divided into a sample testing chamber 101, a sample placement chamber 102, a consumable placement chamber 103, and a waste collection chamber 104. The sample placement port, the first consumable placement port, and the waste collection port are used by operators to place or retrieve items from the outside into the corresponding chambers. This partitioned design facilitates quick identification of the storage locations of different types of items by operators, improving the efficiency of item retrieval and placement. The first chamber cover 201, the second chamber cover 202, and the third chamber cover 203 are also included. The sample placement port, the first consumable placement port, and the waste collection port are respectively covered to seal the main body 100 of the chassis. The robotic arm assembly transfers the testing consumables in the consumable placement chamber 103 to the sample testing chamber 101, the samples in the sample tubes to the testing consumables, and the testing consumables in the sample testing chamber 101 to the waste collection chamber 104 according to the set program. This realizes automated material transfer for the entire sample testing process, reduces manual intervention, and effectively improves testing efficiency.

[0023] Specifically, the lid of the box is equipped with a handle structure to facilitate the operator to hold and open the lid; the testing consumables are selected as PCR plates, which have multiple sample injection wells; or the testing consumables are set as independent PCR tubes.

[0024] In this embodiment of the invention, the first box cover 201 includes at least two first box cover plates, which are joined together to cover the sample placement opening. At least two sample tube racks 303 are provided inside the sample placement chamber 102. Each of the at least two sample tube racks 303 is connected to one of the at least two first box cover plates. Both sample tube racks 303 are retractable and each has a receiving hole for placing sample tubes. Therefore, when placing or removing sample tubes, the operator can pull out one of the sample tube racks 303 independently without affecting the current testing operation of the equipment, enabling sample loading at any time. This is suitable for urgent needs requiring rapid sample loading in scenarios such as hospital emergency rooms.

[0025] Specifically, all sample tube racks 303 are mounted on the same base plate, and the base plate has grooves or rails corresponding to the number of sample tube racks 303.

[0026] Specifically, at least one first box cover is marked, and a sample tube rack 303 connected to the marked first box cover is used to place abnormal sample tubes. Through the marking, operators can quickly identify the purpose of the corresponding sample tube rack 303. Furthermore, the marking can be a pattern, font, or the width of the first box cover can be increased.

[0027] In this embodiment of the invention, the sample testing device further includes a tube clamping mechanism 304, which is disposed within the sample placement chamber 102 and used to clamp the tube body of the sample tube. The robotic arm assembly is used to transfer the sample tube onto the tube clamping mechanism 304. The tube clamping mechanism 304 can fix the tube body of the sample tube, ensuring the stability of the sample tube in subsequent testing processes.

[0028] In this embodiment of the invention, the sample placement chamber 102, the sample detection chamber 101, and the consumable placement chamber 103 are arranged sequentially along the length direction. The tube clamping mechanism 304 is located on the side of the sample placement chamber 102 near the sample detection chamber 101. The top of the main body 100 of the chassis is provided with a first slide rail extending along the length direction. The robotic arm assembly includes a first robotic arm 301 and a second robotic arm 311 that are slidably connected to the first slide rail. The first robotic arm 301 is used to transfer the sample tube to the tube clamping mechanism 304. The second robotic arm 311 is used to transfer the detection consumables in the consumable placement chamber 103 to the sample detection chamber 101, to transfer the sample in the sample tube in the tube clamping mechanism 304 to the detection consumables, and to transfer the detection consumables on the sample detection assembly to the waste collection device in the waste collection chamber 104. Through the coordinated operation of the two robotic arms, the transfer of sample tubes and detection consumables can be completed efficiently, avoiding the time waste caused by the frequent movement of a single robotic arm between multiple workstations.

[0029] In this embodiment of the utility model, the tube clamping mechanism 304 extends along the width direction and is sequentially formed with at least two tube clamping holes. The first robotic arm 301 and the second robotic arm 311 both include a mounting base slidably connected to the first slide rail and a second slide rail provided on the mounting base. The second slide rail extends along the width direction. A sample tube clamping mechanism is connected to the second slide rail of the first robotic arm 301, and a pipetting mechanism and a consumable clamping mechanism are connected to the second slide rail of the second robotic arm 311.

[0030] Specifically, the sample tube has a tube body and a cap. The sample tube clamping mechanism can be used to clamp the sample tube and open the cap. The structure of the sample tube clamping mechanism is selected according to the structure of the sample tube. For example, if the tube body and cap of the sample tube are connected by threads, the sample tube clamping mechanism can be configured to have a rotating clamping mechanism, which clamps the cap and applies a rotational torque to unscrew the cap. If the sample tube has a press-type cap design, the sample tube clamping mechanism can be equipped with a gripper with an elastic pressing component, which first applies a downward pressing unlocking force to the cap, and then clamps the cap to complete the vertical removal action.

[0031] In this embodiment of the invention, the sample testing equipment further includes a sample tube cooling device 302. The sample tube cooling device 302 is located on the side of the sample tube rack 303 away from the sample placement opening. The robotic arm assembly is used to sequentially transfer sample tubes to the sample tube cooling device 302 and then transfer the sample tubes on the sample tube cooling device 302 to the tube clamping mechanism 304. The sample tube cooling device 302 is used to cool the sample tubes to meet the requirements of low-temperature testing. Of course, for samples that do not require low-temperature testing, the robotic arm assembly can directly transfer the sample tubes from the sample tube rack 303 to the tube clamping mechanism 304. The sample tube cooling device 302, located on the side of the sample tube rack 303 away from the sample placement opening, effectively utilizes the internal space of the equipment and avoids interference with the sample tube handling operations.

[0032] Specifically, the cooling device can be equipped with a semiconductor cooling module or a compression cooling unit, which, together with a temperature sensor and control system, enables precise temperature control of the sample tube, ensuring that the sample temperature remains stable within the set range during the cooling process. Furthermore, the surface of the cooling device can be designed with a groove structure that fits the bottom of the sample tube, increasing the contact area between the sample tube and the cooling device and improving cooling efficiency.

[0033] In this embodiment of the invention, the sample testing equipment further includes a quality control reagent tube rack 305, which is located on the side of the tube clamping mechanism 304 near the sample testing station. The quality control reagent tube rack 305 is used to hold sample tubes containing quality control reagents. By comparing the actual test results of the quality control reagents with known standard data, potential errors in the testing system can be detected in a timely manner, providing an important guarantee for the quality control of molecular diagnostic results.

[0034] In this embodiment of the invention, the second box cover 202 includes two second box cover plates, which are joined together to cover the first consumable placement opening. The consumable placement chamber 103 is equipped with a pipette tip holder rack 309 and a reagent tube holder rack 310. Both the pipette tip holder rack 309 and the reagent tube holder rack 310 are retractable and connected to the two second box cover plates respectively. This allows for separate loading of pipette tips and reagents, avoiding interference with other areas of the equipment during consumable replenishment and improving operational convenience. The retractable design of the pipette tip holder rack 309 and the reagent tube holder rack 310 facilitates quick access to and from the pipette tips and reagent tubes by the operator.

[0035] In this embodiment of the invention, a suction tip disposal port 312 is provided on the side of the suction tip holder 309 away from the first consumable placement port. The suction tip disposal port 312 connects the consumable placement chamber 103 and the waste collection chamber 104. The suction tip disposal port 312 is located close to the suction tip holder 309, shortening the working stroke of the second robotic arm 311 when changing suction tips. Specifically, the suction tip holder 309 is located on the side close to the sample detection chamber 101.

[0036] In this embodiment of the invention, the sample testing device further includes a testing consumable box 313, a cover plate consumable rack 307, and an assembly platform 308 disposed within the sample testing chamber 101. The testing consumable box 313 is used to hold testing consumables, the cover plate consumable rack is used to hold cover plate consumables, and the assembly platform 308 has a support position for positioning the testing consumables. The robotic arm assembly is used to sequentially transfer the testing consumables in the testing consumable box 313 to the support position, transfer the sample in the sample tube to the testing consumables in the support position, transfer the cover plate on the cover plate consumable rack 307 to the testing consumables in the support position, and transfer the capped testing consumables to the sample testing assembly. By capping the testing consumables, the evaporation of reagents and external contamination during the testing process can be effectively prevented, ensuring that the subsequent amplification reaction proceeds stably in a closed environment. Moreover, the capping operation is automatically completed by the second robotic arm 311 without human intervention.

[0037] In this embodiment of the invention, the assembly table 308 extends along its length to divide the sample detection chamber 101 into a detection area and a consumable assembly area. The detection area is recessed to form a receiving space, within which the sample detection assembly is located. The detection consumable box 313 and the cover consumable rack 307 are located in the consumable assembly area. The consumable assembly area has a detection consumable disposal port 306, which connects the sample detection chamber 101 and the waste collection chamber 104. This partitioned design of consumable assembly and sample detection avoids cross-interference between different stages. Furthermore, consumable assembly and transfer occur in the same direction. After detection, the second robotic arm 311 retrieves the consumables and returns them to the consumable assembly area for disposal, then proceeds with subsequent consumable assembly, shortening the robotic arm's travel distance and improving detection efficiency. Specifically, the sample detection chamber 101 has a second consumable placement port, and the detection consumable box 313 and the cover consumable rack 307 are mounted on the same mounting plate, which is connected to a fourth box cover 204.
