[0007] Furthermore, the ferry mechanism also includes a meshing drive gear and a driven rack. The drive gear is rotatably mounted on the ferry frame. The second drive member is driven to connect with the drive gear. The driven rack extends vertically and is connected to the first support platform.

[0008] Furthermore, the ferry mechanism also includes a first guide rail and a first chute extending in a vertical direction. The first guide rail is mounted on the ferry frame, and the first chute is mounted on the first support platform. The first chute is movably mounted on the first guide rail along the extension direction of the first guide rail.

[0009] Furthermore, the first support platform includes a first flat plate and a first vertical plate, the upper ends of the first flat plate and the first vertical plate are connected, and the second driving member is drivenly connected to the first vertical plate.

[0010] Furthermore, the second support platform includes a second flat plate and a second vertical plate. The upper ends of the second flat plate and the second vertical plate are connected. An clearance opening is provided on the second flat plate. The lower end of the second vertical plate is connected to the frame.

[0011] Furthermore, the shuttle mechanism also includes a base, on which the shuttle frame is movably mounted along a first horizontal direction.

[0012] Furthermore, the ferry mechanism also includes a transmission belt extending along a first horizontal direction, the transmission belt being disposed on the base, the first drive member being driven connected to the transmission belt, and the transmission belt being driven connected to the ferry frame; and / or, the ferry mechanism also includes a second guide rail and a second slide rail extending along the first horizontal direction, the second guide rail being disposed on the ferry frame, the second slide rail being disposed on the base, and the second slide rail being movably disposed on the second guide rail along the extension direction of the second guide rail.

[0013] Furthermore, the upper surface of the first support platform is a rectangular structure, and the extension direction of the long side of the first support platform is the same as the first horizontal direction; the transfer frame has a first transfer position and a second transfer position in the first horizontal direction, and the transfer frame has a first transfer position and a second transfer position in the second horizontal direction. The second transfer position and the second transfer position coincide in the horizontal direction. When the transfer frame is in the first transfer position, the gripper can move to the top of the first support platform and place medical consumables. When the transfer frame is in the second transfer position and the first support platform is in the first support position, the gripper can move to the top of the first support platform and grab the medical consumables. When the first support platform is in the avoidance position and the transfer frame is in the first transfer position, the gripper can place the medical consumables on the transfer frame.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 9As shown, this embodiment of the invention provides a medical consumables transfer device, which includes a transfer mechanism 10, a transfer mechanism, and a gripping mechanism. The transfer mechanism 10 includes a transfer frame 11, a first driving member 121, a second driving member 122, and a first support platform 13. The first driving member 121 can drive the transfer frame 11 to move along a first horizontal direction, and the second driving member 122 can drive the first support platform 13 to move vertically relative to the transfer frame 11. The transfer mechanism includes a transfer frame and a third driving member, which can drive the transfer frame to move perpendicular to the first horizontal direction. The gripping mechanism includes a gripper that is movable in the vertical and first horizontal directions. The first bearing platform 13 has a first bearing position and a clearance position below the first bearing position. When the first bearing platform 13 is in the first bearing position, the upper surface of the first bearing platform 13 is on the same horizontal plane as the upper surface of the transfer frame, and the gripper can move above the first bearing platform 13 and grip the medical consumables. When the first bearing platform 13 is in the clearance position, the transfer frame can move above the first bearing platform 13, and the gripper can place the medical consumables on the transfer frame.

[0031] The medical consumables transfer device provided in this embodiment includes a ferry mechanism 10, a transfer mechanism, and a gripping mechanism. The medical consumables are placed on a first support platform 13 located at a first bearing position. A first driving member 121 drives a ferry frame 11 to approach a gripper along a first horizontal direction. When the first support platform 13 moves below the gripper, the gripper grips the medical consumables on the first support platform 13. A second driving member 122 drives the first support platform 13 to descend to a clearance position, and a third driving member drives a transfer frame to approach the gripper along a second horizontal direction. When the transfer frame moves above the first support platform 13, the gripper places the medical consumables on the transfer frame. The third driving member then drives the transfer frame away from the gripper along a second horizontal direction, thereby transferring the medical consumables from the ferry frame 11 to the transfer frame. Therefore, by utilizing the movement of the first bearing platform 13 between the first bearing position and the avoidance position, the movement of the transfer frame 11 along the first horizontal direction, and the movement of the transfer frame along the second horizontal direction, the gripper can simply grasp and place medical consumables between the transfer frame 11 and the transfer frame, simplifying the movement stroke of the gripper and improving the transfer efficiency of medical consumables.

[0032] like Figure 1 and Figure 3As shown, the transfer frame 11 includes a frame body 111 and a second support platform 112. A first driving member 121 can drive the frame body 111 to move along a first horizontal direction. The second support platform 112 is disposed on the frame body 111 and has a clearance opening 1121. A first support platform 13 is vertically movable and passes through the clearance opening 1121. The first support platform 13 also has a second support position lower than the first support position. When the first support platform 13 is located in the second support position, the upper surface of the first support platform 13 is not higher than the upper surface of the second support platform 112. By using the above-mentioned second support platform 112, when the size of the medical consumables is large, the medical consumables can be placed on the second support platform 112 by moving the first support platform 13 to the second support position, thereby increasing the support area of ​​the medical consumables.

[0033] In this embodiment, when the first support platform 13 is located in the second support position, the upper surface of the first support platform 13 can be on the same horizontal plane as the upper surface of the second support platform 112, so that the first support platform 13 and the second support platform 112 can jointly support medical consumables, and the second support position and the avoidance position are on the same horizontal plane.

[0034] In other embodiments, when the first support platform 13 is in the second support position, the upper surface of the first support platform 13 is lower than the upper surface of the second support platform 112. At this time, the first support platform 13 does not need to support medical consumables, and only the second support platform 112 is used to support medical consumables.

[0035] like Figures 4 to 6 As shown, the medical consumables include an amplification plate 21, an amplification plate frame membrane 22, and an extraction plate 23. When the first support platform 13 is in the first support position, it supports the amplification plate 21 or the amplification plate frame membrane 22. When the first support platform 13 is in the second support position, it supports the extraction plate 23. Since the height of the extraction plate 23 is greater than the height of the amplification plate 21 and the amplification plate frame membrane 22, in order for the gripper to be able to grasp the medical consumables from the same height, when carrying the extraction plate 23, the first support platform 13 is lowered to the second support position, so that the placement position of the extraction plate 23 is lower than the placement position of the amplification plate 21 or the amplification plate frame membrane 22. This allows the gripper to grasp medical consumables of different heights by lowering a fixed height, simplifying the movement stroke of the gripper and improving the transfer efficiency of the medical consumables.

[0036] like Figure 3As shown, the ferry mechanism 10 also includes a meshing drive gear 141 and a driven rack 142. The drive gear 141 is rotatably mounted on the ferry frame 11. The second drive member 122 is drivenly connected to the drive gear 141. The driven rack 142 extends vertically and is connected to the first support platform 13. The second drive member 122 drives the drive gear 141 to rotate. The drive gear 141 drives the driven rack 142 to move vertically relative to the ferry frame 11 through gear meshing transmission, thereby causing the first support platform 13 to move vertically relative to the ferry frame 11. This allows the first support platform 13 to move between the first support position, the avoidance position, and the second support position, improving the reliability of the movement of the first support platform 13.

[0037] like Figure 3 As shown, the transfer mechanism 10 also includes a first guide rail 151 and a first slide groove extending in a vertical direction. The first guide rail 151 is disposed on the transfer frame 11, and the first slide groove is disposed on the first support platform 13. The first slide groove is movably disposed on the first guide rail 151 along the extension direction of the first guide rail 151. The guiding effect of the first guide rail 151 on the first slide groove improves the reliability of the movement direction of the first support platform 13.

[0038] like Figure 3 As shown, the first support platform 13 includes a first flat plate 131 and a first upright plate 132. The upper ends of the first flat plate 131 and the first upright plate 132 are connected, and the second driving member 122 is drivenly connected to the first upright plate 132. Setting the first sliding groove on the first upright plate 132 can improve the reliability of the movement direction of the first support platform 13, and placing medical consumables on the first flat plate 131 can improve the stability of the placement of medical consumables.

[0039] like Figure 3 As shown, the second support platform 112 includes a second flat plate 1122 and a second upright plate 1123. The upper ends of the second flat plate 1122 and the second upright plate 1123 are connected. A clearance opening 1121 is provided on the second flat plate 1122. The lower end of the second upright plate 1123 is connected to the frame 111. When the first support platform 13 is in the second support position, the upper surface of the first support platform 13 is not higher than the upper surface of the second flat plate 1122. Setting the first guide rail 151 on the second upright plate 1123 can improve the reliability of the movement direction of the first support platform 13. Setting the clearance opening 1121 on the second flat plate 1122 can improve the stability of the placement of medical consumables when placing them on the second flat plate 1122.

[0040] like Figure 1As shown, the transfer mechanism 10 also includes a base 16, and the transfer frame 11 is movably mounted on the base 16 along a first horizontal direction. By moving the transfer frame 11 on the base 16, the movement of the transfer frame 11 is made more stable, preventing medical consumables from falling.

[0041] like Figure 1 As shown, the shuttle mechanism 10 also includes a transmission belt 17 extending along a first horizontal direction. The transmission belt 17 is disposed on the base 16. The first driving member 121 is driven to connect with the transmission belt 17, and the transmission belt 17 is driven to connect with the shuttle frame 11. The first driving member 121 drives the transmission belt 17 to move, thereby causing the shuttle frame 11 to move relative to the base 16 along the first horizontal direction. The transmission belt 17 is used to improve the stability of the movement of the shuttle frame 11.

[0042] like Figure 2 As shown, the transfer mechanism 10 also includes a second guide rail 152 and a second slide groove extending along a first horizontal direction. The second guide rail 152 is disposed on the transfer frame 11, and the second slide groove is disposed on the base 16. The second slide groove is movably disposed on the second guide rail 152 along the extending direction of the second guide rail 152. By utilizing the guiding effect of the second guide rail 152 on the second slide groove, the reliability of the movement direction of the transfer frame 11 is improved.

[0043] Specifically, the second slide is provided on the frame 111.

[0044] like Figures 4 to 6 As shown, the upper surface of the first support platform 13 is rectangular, and the long side of the first support platform 13 extends in the same direction as the first horizontal direction. When the first support platform 13 is in the first support position, it supports the amplification plate 21 or the amplification plate frame membrane 22. At this time, the long side of the medical consumable on the first support platform 13 is parallel to the long side of the first support platform 13. When the first support platform 13 is in the second support position, it supports the extraction plate 23 on the second support platform 112. At this time, the short side of the medical consumable on the first support platform 13 is parallel to the long side of the first support platform 13. This allows the gripper to grasp medical consumables of different sizes within a similar gripper arm extension range, simplifying the gripper's structure and control method. Specifically, the gripper grasps and transfers the amplification plate 21 by its long side, the amplification plate frame membrane 22, or the extraction plate 23 by its short side.

[0045] In this embodiment, the transfer frame 11 has a first transfer position and a second transfer position in the first horizontal direction, and the transfer frame has a first transfer position and a second transfer position in the second horizontal direction. The second transfer position and the second transfer position coincide in the horizontal direction. When the transfer frame 11 is located at the first transfer position, the gripper can move to the top of the first support platform 13 and place medical consumables. When the transfer frame 11 is located at the second transfer position and the first support platform 13 is located at the first support position, the gripper can move to the top of the first support platform 13 and grab the medical consumables. When the first support platform 13 is located in the avoidance position and the transfer frame is located at the first transfer position, the gripper can place the medical consumables on the transfer frame. When the transfer frame is located at the second transfer position, the medical consumables on the transfer frame can be added.

[0046] Another embodiment of the present invention provides a nucleic acid detection integrated machine, which includes a reagent preparation device, a analyte extraction device, and an amplification detection device. The reagent preparation device is used to prepare extraction reagents and amplification reagents. The analyte extraction device is used to extract analytes from samples and combine the analytes with amplification reagents to form a assay mixture. The amplification detection device is used to amplify and detect the assay mixture. The analyte extraction device includes the medical consumable transfer device provided above. Therefore, the nucleic acid detection integrated machine provided in this embodiment can also utilize the movement of the first support platform 13 between the first support position and the avoidance position, the movement of the transfer frame 11 along the first horizontal direction, and the movement of the transfer frame along the second horizontal direction, so that the gripper only needs to simply grasp and place to transfer medical consumables between the transfer frame 11 and the transfer frame, simplifying the movement stroke of the gripper and improving the transfer efficiency of medical consumables.

[0047] Among them, the medical consumables transfer device is used to transfer medical consumables between the reagent preparation device and the analyte extraction device.

[0048] Specifically, extraction reagents and amplification reagents are prepared using a reagent preparation device. The extraction reagents and amplification reagents are then transported separately to a sample processing device. The sample processing device mixes the sample with the extraction reagents for extraction. The analytes are then combined with the amplification reagents to form a assay mixture. The assay mixture is transported to an amplification detection device. After amplification of the analytes in the assay mixture, the assay mixture is analyzed and detected to obtain the test results of the sample.
