[0031] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic three-dimensional assembly structure diagram of an embodiment of the reagent storage device 10 provided by the present application, Figure 2 is Figure 1 a schematic three-dimensional exploded structure diagram of the reagent storage device 10 in
[0032] Among them, the storage body 11 is formed with a storage space 101 and a pick-and-place opening 102 communicating with the storage space 101. The storage space 101 is used to store reagents. In practical applications, reagents are generally stored in reagent containers such as reagent bottles and reagent cans first, and then the reagent containers such as reagent bottles and reagent cans are placed in the storage space 101 through the pick-and-place opening 102. When it is necessary to replace the reagent, for example, when the reagent in the reagent container is used up, or when the reagent in the reagent container has not been used for a long time and needs to be replaced with a new reagent, the reagent container can be taken out through the pick-and-place opening 102 to complete the replacement operation of the reagent.
[0033] Optionally, in this embodiment, the storage body 11 includes a housing 111 and a cover 112. The housing 111 is formed with a storage space 101 and an opening 103 communicating with the storage space 101. The cover 112 is formed with the above-mentioned pick-and-place opening 102. The cover 112 is covered on the opening 103 so that the pick-and-place opening 102 communicates with the storage space 101.
[0034] Please refer to Figure 3 and Figure 4 , Figure 3 is Figure 2 the schematic exploded three-dimensional structure diagram of the handle module 12 in Figure 4 is Figure 1 the schematic cross-sectional view of the handle module 12 and the cover 112 along the K1-K1 direction. The handle and cover module 12 includes a handle cover 121, a handle assembly 122 and a packaging member 123.
[0035] Among them, the handle cover 121 is covered on the pick-and-place opening 102, and the handle assembly 122 is rotatably connected to the handle cover 121.
[0036] Specifically, the handle cover 121 is provided with a mounting hole 104. The handle assembly 122 includes a handle 1221, a first connecting member 1222 and a second connecting member 1223. The first connecting member 1222 passes through the mounting hole 104. The handle 1221 and the second connecting member 1223 are respectively connected to the first connecting member 1222 at both ends of the first connecting member 1222, so that the handle 1221 and the second connecting member 1223 are respectively located on opposite sides of the handle cover 121. When the handle 1221 is rotated by an external force, the second connecting member 1223 is driven to rotate relative to the handle cover 121 through the first connecting member 1222.
[0037] Furthermore, one of the packaging member 123 and the handle assembly 122 is provided with a guide groove 105, and the other of the packaging member 123 and the handle assembly 122 is provided with a guide member 123a. In this embodiment, taking the handle assembly 122 being provided with the guide groove 105 and the packaging member 123 being provided with the guide member 123a as an example for illustration, the guide groove 105 is provided on the second connecting member 1223.
[0038] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 5 which Figure 4 are front schematic views of the lifting cover 121, the second connecting member 1223, and the encapsulation member 123 in the M direction in Figure 6 which Figure 5 is a schematic view of the state of the encapsulation member 123 away from the rotation axis I of the handle assembly 122 in Figure 7 which Figure 4 is an enlarged schematic view of the N1 part in Figure 8 which Figure 7 is a schematic view of the state where the encapsulation member 123 is disengaged from the cover body 112. The guide member 123a is arranged in cooperation with the guide groove 105. When the handle assembly 122 rotates relative to the lifting cover 121, the guide member 123a moves along the extension direction of the guide groove 105, and drives the encapsulation member 123 to move in the direction away from or close to the rotation axis I of the handle assembly 122, so that the encapsulation member 123 is in an encapsulated state or a disengaged state from the storage main body 11, and further enables the lifting cover 121 to encapsulate or open the access port 102. Through this setting method, when the reagent needs to be replaced, only the handle assembly needs to be rotated. Compared with the prior art, there is no need to disassemble the connection mechanism such as bolts, the operation is simple, and the convenience of reagent replacement is improved.
[0039] Specifically, the guide groove 105 is an arc groove, and the arc groove extends in the direction away from the rotation axis I of the handle assembly 122. An encapsulation groove 106 is provided on the storage main body 11. In this embodiment, taking Figure 5 the rightmost guide groove 105 in Figure 5 as an example for illustration. At this time, the distance between the position of the guide member 123a in the guide groove 105 and the rotation axis I of the handle assembly 122 is L1. When the second connecting member 1223 rotates upward in A1 as shown in Figure 6 , since the guide groove 105 extends in the direction away from the rotation axis I of the handle assembly 122, during the process of the guide member 123a moving along the extension direction of the guide groove 105, the distance between the guide member 123a and the rotation axis I of the handle assembly 122 gradually increases, that is, as shown in Figure 7As shown, the package 123 is inserted into the package slot 106 of the storage body 11. At this time, the package 123 and the storage body 11 are in a packaged state, and the lifting cover 121 packages the access opening 102; similarly, when the second connecting member 1223 rotates upward as shown in Figure 6 A2, during the process that the guide member 123a moves along the extension direction of the guide groove 105, the distance between the guide member 123a and the rotation axis I of the handle assembly 122 gradually decreases, so that the distance between the package 123 connected to the guide member 123a and the rotation axis I of the handle assembly 122 also gradually decreases, thereby causing the guide member 123a to move in the direction close to the rotation axis I of the handle assembly 122 until as shown in Figure 8 A2, the package 123 is removed from the package slot 106 of the storage body 11. At this time, the package 123 and the storage body 11 are separated from the packaged state, and the lifting cover 121 can then open the access opening 102.
[0040] Optionally, the number of the guide grooves 105, the packages 123, and the guide members 123a are respectively multiple. In this embodiment, three guide grooves 105, three packages 123, and three guide members 123a are taken as examples.
[0041] Furthermore, the guide member 123a is rotationally connected to the handle assembly 122 or the package 123, so that the package 123 moves on the radial direction F1 or radial direction F2 perpendicular to the rotation axis I of the handle assembly 122. In this embodiment, the guide member 123a is rotationally connected to the package 123 as an example.
[0042] Specifically, since the movement of the guide member 123a along the extension direction of the guide groove 105 is caused by the rotation of the handle assembly 122, when the guide member 123a moves in the direction away from or towards the rotation axis I of the handle assembly 122, it not only receives the force in the radial direction F1 or F2, but also receives the force in the rotation direction of the handle assembly 122. Then, if the guide member 123a is fixedly connected to the encapsulation member 123, it will cause the encapsulation member 123 to not only receive the force in the radial direction F1 or F2, but also receive the force in the rotation direction of the handle assembly 122. As a result, under the action of these two forces, during the process of moving away from or towards the rotation axis I of the handle assembly 122, the encapsulation member 123 rotates relative to the lid 121, which will lead to a longer movement stroke of the encapsulation member 123 and a larger occupied movement space. In this embodiment, by rotatably connecting the guide member 123a to the encapsulation member 123, when the guide member 123a moves along the extension direction of the guide groove 105, the guide member 123a rotates relative to the encapsulation member 123, so that the force in the rotation direction of the handle assembly 122 received by the guide member 123a will not be transmitted to the encapsulation member 123. The encapsulation member 123 only receives the force in the radial direction F1 or F2, and under the action of the force in the radial direction F1 or F2, it moves away from or towards the rotation axis I of the handle assembly 122 in the radial direction F1 or F2, reducing the movement stroke of the encapsulation member 123 and lowering the movement space.
[0043] Please refer to Figure 9 , Figure 9 is Figure 5 a three-dimensional structural schematic diagram of the lid 121 in [reference]. In this embodiment, the lid 121 is further provided with a limiting channel 107. The limiting channel 107 extends in the radial direction F1 or F2 perpendicular to the rotation axis I of the handle assembly 122, and the encapsulation member 123 is movably arranged in the limiting channel 107.
[0044] Specifically, although the above-mentioned method of rotatably connecting the guide member 123a to the handle assembly 122 or the encapsulation member 123 makes the force in the rotation direction of the handle assembly 122 received by the guide member 123a not be transmitted to the encapsulation member 123, during the rotation of the guide member 123a relative to the handle assembly 122 or the encapsulation member 123, there will still be friction, and this friction will also cause the guide member 123a to drive the encapsulation member 123 to rotate when rotating. Therefore, in this embodiment, through the setting of the limiting channel 107, the encapsulation member 123 moves in the extension direction of the limiting channel 107, providing a limiting effect on the movement direction of the encapsulation member 123.
[0045] Please refer to Figure 6 , Figure 9 and Figure 10 , Figure 10 is Figure 6Schematic cross-sectional view of the middle lift cover 121 and the second connecting member 1223 along the K2-K2 direction. Among them, the lift cover 121 is provided with a first positioning portion 121a, and the handle assembly 122 is provided with a second positioning portion 122a. The first positioning portion 121a and the second positioning portion 122a are configured to be in a cooperative setting when the handle assembly 122 rotates to a preset position. For example, when the handle assembly 122 rotates to the position where the encapsulation member 123 and the storage main body 11 are in an encapsulated state and / or a state of being separated from the encapsulated state, the first positioning portion 121a and the second positioning portion 122a are in a cooperative setting to position the rotation process of the handle assembly 122.
[0046] Among them, one of the first positioning portion 121a and the second positioning portion 122a is a positioning hole, and the other of the first positioning portion 121a and the second positioning portion 122a is an elastic positioning protrusion. In this embodiment, taking the first positioning portion 121a as the elastic positioning protrusion and the second positioning portion 122a as the positioning hole as an example, the positioning hole of the second positioning portion 122a is provided on the second connecting member 1223 of the handle assembly 122.
[0047] Specifically, in practical applications, generally, the handle assembly 122 is rotated manually by hand. When the handle assembly 122 is not rotated to the preset position, the elastic positioning protrusion undergoes elastic deformation under the extrusion of the handle assembly 122. In this embodiment, that is, under the extrusion of the second connecting member 1223. When the handle assembly 122 rotates to the preset position, the elastic positioning protrusion slides into the positioning hole and is in a cooperative setting with the positioning hole. At this time, the elastic positioning protrusion rebounds under the action of elastic force, and this rebound phenomenon will cause the handle assembly 122 to vibrate, and this vibration can be felt by the human hand, thereby realizing tactile positioning and improving the positioning accuracy during the rotation of the handle assembly 122.
[0048] Among them, the lift cover 121 or the handle assembly 122 is provided with a mounting groove (not marked in the figure). In this embodiment, that is, the lift cover 121 is provided with a mounting groove. The elastic positioning protrusion includes a support body 121b and an elastic body 121c. The support body 121b is arranged in the mounting groove, and the elastic body 121c is exposed outside the mounting groove on the side of the support body 121b close to the positioning hole.
[0049] Please refer to Figure 6 and Figure 11 , Figure 11 is Figure 3An enlarged schematic diagram of the N2 part. Optionally, the number of positioning holes is multiple, and the multiple positioning holes are arranged at intervals in sequence along the rotation direction of the handle assembly 122. A guiding channel 108 is provided between two adjacent positioning holes. With this setting method, on the one hand, it enables the elastic positioning protrusion to slide along the guiding channel 108 between two adjacent positioning holes, playing a limiting role in the movement of the elastic positioning protrusion. On the other hand, it reduces the elastic deformation generated when the elastic positioning protrusion is squeezed, avoiding excessive deformation, which may lead to too much resistance to the rotation of the handle assembly 122 or damage to the elastic positioning protrusion. In this embodiment, taking the number of positioning holes as two as an example, the elastic positioning protrusion is in a cooperative setting with one of the positioning holes when the encapsulation member 123 and the storage main body 11 are in an encapsulated state, and is in a cooperative setting with the other positioning hole when the encapsulation member 123 and the storage main body 11 are out of the encapsulated state.
[0050] An embodiment of the present application also provides a sample analyzer, which includes a detection device and the reagent storage device 10 in the above embodiment.
[0051] Among them, the detection device is used to detect the mixed solution of the reagent stored in the reagent storage device 10 and the sample to be detected.
[0052] It can be understood that in this embodiment, the specific type of the sample analyzer and the specific detection method of the detection device are not limited. For example, the sample analyzer can be a male, female, blood analyzer, etc.
[0053] The beneficial effect of the present application is: Different from the prior art, the lid-lifting module provided by the present application includes: a lid; a handle assembly rotatably connected to the lid; an encapsulation member, one of the handle assembly and the encapsulation member is provided with a guiding groove, and the other of the handle assembly and the encapsulation member is provided with a guiding member, and the guiding member is cooperatively arranged with the guiding groove, so that when the handle assembly rotates relative to the lid, the guiding member moves along the extending direction of the guiding groove and drives the encapsulation member to move in a direction away from or close to the rotation axis of the handle assembly. With this setting method, when it is necessary to replace the reagent, only the handle assembly needs to be rotated. Compared with the prior art, there is no need to disassemble connection mechanisms such as bolts, the operation is simple, and the convenience of reagent replacement is improved.
[0054] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application.
