[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Please refer to Figures 1 to 10 , Figure 1 It is a schematic diagram of assembling the consumable box loading device 1 and the consumable box provided in the embodiment of the present application; Figure 2 A schematic diagram of the structure of the consumable box loading device 1 provided in an embodiment of the present application in a first direction; Figure 3 A schematic diagram of the structure of the consumable box loading device 1 provided in an embodiment of the present application in the second direction; Figure 4 A schematic diagram of the structure of the consumable box loading device 1 provided in an embodiment of the present application in a third direction; Figure 5 A schematic diagram of the structure of the first consumable box provided in an embodiment of the present application; Figure 6 A schematic diagram of a partial structure of a first consumables box provided in an embodiment of the present application; Figure 7 A schematic diagram of the structure of a second consumables box provided in an embodiment of the present application; Figure 8 A schematic diagram of a partial structure of a second consumables box provided in an embodiment of the present application; Fig. 9 It is a schematic diagram of the assembly of the consumable box loading device 1 and the consumable box provided in an embodiment of the present application at the first elastic plunger and the plunger hole; Fig.10 This is a schematic diagram of the assembly of the consumable box loading device 1 and the consumable box at the guide groove, the guide column, the first limiting protrusion and the second limiting protrusion provided in an embodiment of the present application.

[0037] Please refer to Figure 1 and Figure 2 The present application provides a consumable box loading device 1, comprising a first mounting seat 11 and a second mounting seat 12 arranged on the first mounting seat 11; the first mounting seat 11 is used to fix the connection with the consumable processing instrument, for example, the first mounting seat 11 can be locked and positioned in the operating cavity of the consumable processing instrument by a fastener; the second mounting seat 12 is provided with a positioning groove for plugging and unplugging the consumable box 2, in other words, the second mounting seat 12 uses the positioning groove to hold the consumable box 2.

[0038] In this embodiment, the second mounting seat 12 is provided with one or more positioning grooves; for any positioning groove, the top end of the positioning groove is exposed, a pair of groove side plates 131 are provided on both sides of the positioning groove, and a groove bottom plate 132 is provided at the bottom of the positioning groove; the pair of groove side plates 131 are distributed at intervals, and the consumable box 2 inserted into the positioning groove is located between the pair of groove side plates 131; the groove side plates 131 and / or the groove bottom plate 132 are provided with a mechanical limit portion; the pair of groove side plates 131 and the mechanical limit portion are used to limit the freedom of movement of the consumable box 2 along the X, Y, and Z axes.

[0039] When the slot side plate 131 and the mechanical limiter are used to limit the freedom of movement of the consumable box 2 along the X, Y, and Z axes, the X axis can be regarded as Figure 2 The Y axis can be regarded as the left and right direction. Figure 2 The Z axis can be regarded as the front-to-back direction. Figure 2 When the slot side plate 131 and the mechanical limiter are used to limit the freedom of movement of the consumable box 2 along the three axes of X, Y, and Z, the slot side plate 131 and the mechanical limiter can respectively limit the freedom of movement of the consumable box 2 in different directions in the consumable box loading device 1, and the slot side plate 131 and the mechanical limiter can also be used together to limit the freedom of movement of the consumable box 2 in a certain direction in the consumable box loading device 1. Among them, the mechanical limiter can be set to various point, line, and surface mechanical components that can block the movement of the consumable box 2.

[0040] In this embodiment, the first mounting seat 11 can be set as a bracket structure, for example, the first mounting seat 11 includes a first side support plate, a reinforcement plate and a bottom plate; the bottom plate is fixed to the top of a plurality of first side support plates, and a reinforcement plate is provided between the plurality of first side support plates. Part of the bottom plate can be used as a groove bottom plate 132 of the positioning groove, and at the same time, the second mounting seat 12 includes a plurality of second side support plates provided on the bottom plate, and any two adjacent side support plates and the bottom plate therebetween jointly define a positioning groove.

[0041] When the consumable box loading device 1 provided by the present application is used to implement the loading operation of the consumable box 2 in the consumable processing instrument, the consumable box loading device 1 is arranged in the consumable processing instrument, and the operator can directly take and place the consumable box 2 in the consumable processing instrument. At the same time, the consumable box loading device 1 uses the positioning groove to clamp the consumable box 2, and the top of the positioning groove is exposed, so the operator can also directly take and place the consumables from the consumable box 2 in the consumable processing instrument. Usually, the consumable box loading device 1 provided by the present application can be used in conjunction with an automated device that can automatically operate consumables. For example, the automated device is provided with a robotic arm and a sampling needle, and the sampling needle is arranged at the end of the robotic arm. The robotic arm extends the sampling needle from the outside of the consumable processing instrument into the consumable processing instrument, so that the sampling needle operates the consumables in the consumable box 2 in the consumable processing instrument.

[0042] The consumable box loading device 1 provided in the present application provides a fixed installation position for the consumable box 2 in the consumable processing instrument. When the consumable box 2 and the consumables therein need to be moved, there is no need to remove the consumable box loading device 1 from the consumable processing instrument. The consumable box 2 and the consumables therein can be directly pulled out from the consumable box loading device 1. Conversely, when a new consumable box 2 and the consumables therein need to be placed in the consumable processing instrument, the new consumable box 2 and the consumables therein can be directly moved into the consumable processing instrument and inserted into the consumable box loading device 1, and the positioning groove and the mechanical limit part of the consumable box loading device 1 can be used to accurately position the consumable box 2 and the consumables therein.

[0043] It can be seen that, compared with the common closed consumable box loading device 1, the consumable box loading device 1 provided in the present application can be fixedly installed in the consumable processing instrument, providing a free access and precise positioning installation position for the consumable box 2 and the consumables in the consumable processing instrument. The above-mentioned measures can reduce the number of motion relationships between the consumable processing instrument, the consumable box loading device 1 and the consumable box 2, that is, can reduce the number of movable parts required for the consumable processing instrument, the consumable box loading device 1 and the consumable box 2, thereby simplifying the operation process, reducing the life risk caused by movable parts, and avoiding the problem of inaccurate positioning of the consumable box 2 caused by excessive assembly errors of the entire device.

[0044] The consumable box loading device 1 provided in the present application is further described below in conjunction with the accompanying drawings and implementation examples.

[0045] For reference Figure 1 and Figure 2 The consumable box loading device 1 provided in the present application uses a groove side plate 131 and a mechanical limiter to limit the freedom of movement of the consumable box 2 along the X, Y, and Z axes. In some embodiments, the mechanical limiter includes a first elastic plunger 141, one end of the first elastic plunger 141 is buried in the second mounting seat 12, and the other end of the elastic plunger extends into the positioning groove. In other words, the other end of the first elastic plunger 141 extends into the groove cavity of the positioning groove. The first elastic plunger 141 of the consumable box loading device 1 cooperates with the plunger hole 21 of the consumable box 2 to realize the positioning of the consumable box 2 in the consumable box loading device 1. Usually, the first elastic plunger 141 is a ball head plunger, and the ball head of the ball head plunger extends into the groove cavity of the positioning groove. The plunger hole 21 of the consumable box 2 is a hemispherical groove for the aforementioned ball head to be embedded.

[0046] In the above embodiment, when the consumable box 2 is inserted into the positioning slot of the consumable box loading device 1, when the consumable box 2 has not yet been inserted into place, the outer surface of the consumable box 2 squeezes the ball head of the ball plunger. At this time, the consumable box 2 can continue to move along the extension direction of the positioning slot. When the consumable box 2 is inserted into place, the ball head of the ball plunger is aligned with and inserted into the plunger hole 21 of the consumable box 2, thereby realizing the constrained positioning of the consumable box 2 and the consumable box loading device 1 in the extension direction of the positioning slot. In other words, the ball plunger is used to limit the freedom of movement of the consumable box 2 along the extension direction of the positioning slot.

[0047] For reference Figures 1 to 4 On the basis of the above embodiment, the mechanical limiter not only includes the first elastic plunger 141, but also includes the second elastic plunger 142; one end of the second elastic plunger 142 is buried in the second mounting seat 12, and the other end of the first elastic plunger 141 extends into the groove cavity of the positioning groove. In this embodiment, the first elastic plunger 141 is arranged on the groove bottom plate 132, and is used for plugging and connecting with the plunger hole 21 of the consumable box 2, so as to limit the freedom of movement of the consumable box 2 along the extension direction of the positioning groove; the second elastic plunger 142 is arranged on the groove side plate 131, and is used for pressing the box side wall of the consumable box 2, so as to realize the limitation of the freedom of movement of the consumable box 2 in the width direction of the positioning groove together with a pair of groove side plates 131.

[0048] Typically, the second elastic plunger 142 is disposed on and only disposed on one of the slot side plates 131 of the positioning slot.

[0049] In the above embodiment, the spacing between a pair of groove side plates 131 of the positioning groove is equal to the width of the positioning groove; the width of the positioning groove is slightly larger than the width of the consumable box 2, which facilitates the insertion and removal of the consumable box 2 in the positioning groove. The second elastic plunger 142 provided on one side of the positioning groove pushes the consumable box 2 toward the other side of the positioning groove to prevent the consumable box 2 from shaking along the width of the positioning groove.

[0050] For reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Fig.10On the basis of the above embodiment, the mechanical limiter also includes a second guide plane 15; the second guide plane is arranged on the slot side plate 131 and is horizontally distributed. When the consumable box 2 is inserted into the positioning slot, the second guide plane is in contact with the first guide plane 24 of the consumable box 2, which can limit the freedom of movement of the consumable box 2 in the depth direction of the positioning slot. The second guide plane 15 is arranged on the slot side plate 131, and it can be distributed downward or upward. Obviously, when the second guide plane 15 is horizontally downward, the first guide plane 24 of the consumable box 2 is horizontally upward, and the first guide plane 24 and the second guide plane 15 are in contact with each other. Conversely, when the second guide plane 15 is horizontally upward, the first guide plane 24 of the consumable box 2 is horizontally downward, and the first guide plane 24 and the second guide plane 15 are in contact with each other.

[0051] Based on the above embodiments, Figure 4 and Fig.10 As shown, the groove side plate 131 is provided with a guide groove; the guide groove and the positioning groove extend in the same direction, and the groove top surface of the guide groove is the second guide plane 15. In this example, the second guide plane 15 is arranged on the groove top surface of the guide groove, that is, the second guide plane 15 is horizontally downward. When the consumable box 2 is inserted into the positioning groove, the entire side surface of the consumable box 2 can be embedded in the guide groove, that is, the top surface of the consumable box 2 is the first guide plane 24 of the consumable box 2. In addition, the side surface of the consumable box 2 can also be provided with a guide slider that can be embedded in the guide groove and slide along the guide groove. Obviously, at this time, the top surface of the guide slider is the first guide plane 24 of the consumable box 2. In this embodiment, the second guide plane 15 of the guide groove can jointly limit the freedom of movement of the consumable box 2 in the depth direction of the positioning groove with the first elastic plunger 141. For example, when the ball head of the first elastic plunger 141 is embedded in the plunger hole 21 at the bottom of the consumable box 2, the first elastic plunger 141 is in a compressed state, which can make the second guide plane 15 of the guide groove and the first guide plane 24 of the consumable box 2 close to each other, thereby ensuring the positioning accuracy of the consumable box 2 in the depth direction of the positioning groove.

[0052] For reference Figure 1 and Fig.10 On the basis of the above embodiment, a second limiting protrusion 16 is provided on the bottom surface of the guide groove, and the second limiting protrusion 16 can abut against the first limiting protrusion 25 of the consumable box 2 to prevent the consumable box 2 from continuing to be inserted into the positioning groove, and can jointly ensure the positioning accuracy of the consumable box 2 in the extension direction of the positioning groove with the first elastic plunger 141.

[0053] Still available for reference Figure 1 and Fig.10In some embodiments, the guide groove may include a trumpet-shaped notch 171 and a long strip groove 172; the trumpet-shaped notch 171 and the long strip groove 172 are sequentially connected along the extension direction of the guide groove; the second guide plane 15 and the second limiting protrusion 16 are both provided on the long strip groove 172. From the perspective of the insertion and removal direction of the consumable box 2 in the positioning groove, the trumpet-shaped notch 171 is located in the front and the long strip groove 172 is located in the back. When the consumable box 2 is inserted into the positioning groove, the consumable box 2 first contacts the trumpet-shaped notch 171, then penetrates into the trumpet-shaped notch 171, and then slides along the long strip groove 172. The trumpet-shaped notch 171 can reduce the difficulty of installing the consumable box 2, and the consumable box 2 can be conveniently and quickly inserted into the positioning groove and the guide groove.

[0054] In some of the embodiments provided above, the number of positioning grooves is multiple; all positioning grooves include multiple first positioning grooves and multiple second positioning grooves, the groove depth of any first positioning groove is less than the groove depth of any second positioning groove, and the tops of all first positioning grooves and the tops of all second positioning grooves are in the same plane. In this embodiment, the groove depths of the first positioning grooves and the second positioning grooves are different, which is suitable for inserting and positioning different types of consumable boxes 2, and the type of consumable box 2 often depends on the type of consumables. For example, PCR tubes and PCR caps are suitable for the same type of consumable box 2, and Tip heads are suitable for another type of consumable box 2. The height of the consumable box 2 suitable for PCR tubes and PCR caps is often less than the height of the consumable box 2 suitable for Tip heads. For this reason, multiple consumable boxes 2 suitable for PCR tubes and PCR caps can be inserted into multiple first positioning grooves one by one, and multiple consumable boxes 2 suitable for Tip heads can be inserted into multiple first positioning grooves one by one.

[0055] In addition, in some of the embodiments provided above, the rear plate of the positioning slot is an RFID reading circuit board 18 or an RFID reader, which is used to read the RFID tag 26 of the consumable box 2. Figure 1 , Figure 2 , Figure 6 and Figure 8 A consumable box loading device 1 includes a plurality of first positioning slots, a plurality of second positioning slots and two RFID reading circuit boards 18, wherein one RFID reading circuit board 18 serves as a slot back plate for all the first positioning slots, and the other RFID reading circuit board 18 serves as a slot back plate for all the second positioning slots. Based on the RFID reading circuit board 18 of the consumable box loading device 1 and the RFID tag 26 of the consumable box 2, the consumable box loading device 1 can automatically obtain sample information of the consumable box 2 and the consumables therein during the test, which is conducive to the dataization of the consumable test operation. For any RFID reading circuit board 18, it is provided with a plurality of RFID sensing areas, and these RFID sensing areas are aligned with the corresponding RFID tags 26 of the plurality of consumable boxes 2.

[0056] The present application also provides a consumables box 2, which can be applied to the consumables box loading device 1 provided in the above embodiments. Figure 5 , Figure 7 and Fig.10 The consumable box 2 includes a box body 22 and a handle 23; the interior of the box body 22 is provided with a consumable positioning hole 27 for plugging and unplugging consumables, the consumable positioning hole 27 extends along the up and down directions of the box body 22, the top of the consumable positioning hole 27 is exposed upward, and the consumables can be inserted into the consumable positioning hole 27 from top to bottom; the exterior of the box body 22 is provided with a plunger hole 21, a first guide plane 24, a first limiting protrusion 25 and an RFID tag 26.

[0057] Among them, the plunger hole 21 is used in conjunction with the first elastic plunger 141 of the consumable box loading device 1, the first guide plane 24 is used in conjunction with the second guide plane 15 of the consumable box loading device 1, the first limit protrusion 25 is used in conjunction with the second limit protrusion 16 of the consumable box loading device 1, and the RFID tag 26 is used in conjunction with the RFID reading circuit board 18 or the RFID reader of the consumable box loading device 1.

[0058] For reference Figure 5 , Figure 7 and Fig.10 Typically, three guide bars 28 are provided on both sides of any consumable box 2 , and the upper surface of any guide bar 28 is a first guide plane 24 . The guide bar 28 in the middle of the same consumable box 2 is provided with a first limiting protrusion 25 .

[0059] In the above embodiment, a consumable box 2 is usually provided with a plurality of consumable positioning holes 27. The hole depths of the consumable positioning holes 27 of different types of consumable boxes 2 are often different, and can be used to insert different types of consumables. In addition, in addition to the parameter of hole depth, parameters such as the shape of the holes and the cross-sectional dimensions of the holes of different types of consumable boxes 2 may also differ.

[0060] The consumable box 2 provided in the present application is suitable for the consumable box loading device 1 provided in the present application; the aforementioned consumable box loading device 1 and the aforementioned consumable box 2 cooperate with each other to meet the precise positioning of consumables in the consumable processing instrument, and can reduce the number of movable parts required for the consumable processing instrument, the consumable box loading device 1 and the consumable box 2, simplify the operation process, reduce the life risk caused by movable parts, and avoid the problem of inaccurate positioning of the consumable box 2 caused by excessive assembly errors of the entire device. Among them, the consumable processing instrument can be a biological testing instrument such as a molecular diagnostic instrument. When a molecular diagnostic instrument is used to perform diagnostic tests on molecular samples, the consumables can be used as containers for carrying molecular samples. The consumable box 2 provided in the present application and the consumable box loading device 1 provided in the present application can easily and quickly load and position a number of consumables accurately and reliably in the molecular diagnostic instrument, and can also ensure that the consumable box 2 can be replaced without stopping the molecular diagnostic instrument.

[0061] In summary, the consumable box 2 provided in the present application and the consumable box loading device 1 provided in the present application are used in combination, and the consumable box loading device 1 is fixed in a consumable processing instrument such as a molecular diagnostic instrument. Therefore, when taking and placing the consumable box 2, it is only necessary to push and pull the consumable box 2 from the aforementioned consumable box loading device 1, and there is no need to first take out the loading device from the consumable processing instrument and then take out the consumable box 2 from the loading device, which improves the convenience of operation and reduces the equipment cost and equipment failure rate.
