[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Such as Figures 1 to 5As shown in the figure, an embodiment of the present invention provides a sample analyzer 100, which includes a reagent carrier assembly 10, a reagent container group 20, a base 30, and an open lid assembly 40. The reagent carrier assembly 10 is provided with a plurality of reagent positions 11. The reagent container group 20 is placed on the reagent positions 11. The reagent container group 20 includes a reagent container 21 provided with a receiving hole 211 for receiving a magnetic bead bottle 22. The magnetic bead bottle 22 includes a bottle body 221 and a bottle cap 222 connected to the bottle body 221. The bottle body 221 is rotatably disposed in the receiving hole 211. The base 30 is disposed below the reagent carrier assembly 10 and is disposed opposite to the receiving hole 211. The open lid assembly 40 includes an open lid member 41 and an open lid driving assembly 42 for driving the open lid member 41 to move. The open lid member 41 is disposed above the reagent carrier assembly 10, and the open lid member 41 is used to open the bottle cap 222 of the magnetic bead bottle 22. Among them, the magnetic bead bottle 22 is provided with a first positioning member 223, and the base 30 is provided with a second positioning member 31. The first positioning member 223 and the second positioning member 31 are snap-connected so that the magnetic bead bottle 22 received in the receiving hole 211 is non-rotatably clamped to the base 30.

[0032] In the sample analyzer 100 proposed by the embodiment of the present invention, by providing a first positioning member 223 on the magnetic bead bottle 22 and a second positioning member 31 on the base 30, and the first positioning member 223 and the second positioning member 31 are snap-connected, so that when the magnetic bead bottle 22 and the base 30 are snap-connected, they can be fixed relative to the base 30. In this way, when the base 30 is fixed, it can play a role in fixing and orienting the bottle cap 222 of the magnetic bead bottle 22 received in the receiving hole 211, so that the subsequent open lid assembly 40 can smoothly open the bottle cap 222 of the magnetic bead bottle 22, and when the base 30 rotates, it can drive the magnetic bead bottle 22 to rotate to mix the magnetic bead reagent contained in the magnetic bead bottle 22.

[0033] As Figure 4 and Figure 5 shown, in one embodiment, the first positioning member 223 is a positioning protrusion 2231 provided on the magnetic bead bottle 22, and the second positioning member 31 is a positioning slot 311 provided on the base 30. When the magnetic bead bottle 22 is received in the receiving hole 211, the positioning protrusion 2231 is embedded in the positioning slot 311. It should be noted that the positions of the positioning protrusion 2231 and the positioning slot 311 can be interchanged, that is, the positioning protrusion 2231 can be provided on the base 30, and the positioning slot 311 can be provided on the magnetic bead bottle 22, which can be determined according to actual design needs.

[0034] As Figure 4As shown, in one embodiment, the base 30 includes a base body 32 and a plurality of flap bodies 33 connected to the base body 32. The plurality of flap bodies 33 are distributed around the central axis of the base 30 and are spaced apart from each other. The gap between two adjacent flap bodies 33 forms a positioning card slot 311. The magnetic bead bottle 22 further includes a plurality of rib plates 224. The plurality of rib plates 224 are provided at the bottom of the bottle body 221, are distributed around the central axis of the magnetic bead bottle 22 and are spaced apart from each other. The rib plates 224 form positioning protrusions 2231.

[0035] As Figure 4 shown, in one embodiment, the number of flap bodies 33 and the number of rib plates 224 are six. Of course, the number of flap bodies 33 is not limited to six, and can also be two, three, four, five, seven or more, which can be determined according to actual design needs. The number of rib plates 224 is not limited to six either, and can also be one or two, three, four, five, seven or more corresponding to the number of rib plates 224, which can be determined according to actual design needs.

[0036] As Figure 4 shown, in one embodiment, the flap body 33 includes a first end and a second end opposite to the first end. The first end of the flap body 33 is connected to the base body 32. The flap body 33 includes a first side surface 33a and a second side surface 33b in the rotation direction of the base 30. In two adjacent flap bodies 33, the gap between the first side surface 33a of one flap body 33 and the second side surface 33b of the other flap body 33 forms a positioning card slot 311. The flap body 33 further includes a first guiding surface 33c and a second guiding surface 33d. The first guiding surface 33c extends obliquely from the second end of the flap body 33 towards the base body 32 to be connected to the first side surface 33a, and the second guiding surface 33d extends obliquely from the second end of the flap body 33 towards the base body 32 to be connected to the second side surface 33b. In this embodiment, by providing the flap body 33 with the first guiding surface 33c and the second guiding surface 33d, the first guiding surface 33c and the second guiding surface 33d can guide the rib plates 224 of the magnetic bead bottle 22 into the positioning card slot 311 of the base 30, reducing the difficulty of connecting the magnetic bead bottle 22 to the base 30. Of course, in some other embodiments, it is also possible that the flap body 33 does not have the first guiding surface 33c and the second guiding surface 33d, which can be determined according to actual design needs. Optionally, the first side surface 33a and the second side surface 33b are parallel to the central axis of the base 30.

[0037] As Figures 4 to 6As shown, in one embodiment, the bottle body 221 includes a bottle body 2211 and a bottle bottom 2212. The bottle body 2211 includes a bottle mouth end A1 and a bottle bottom end A2 opposite to the bottle mouth end A1. The bottle bottom 2212 is connected to the bottle bottom end A2. The outer surface S of the bottle bottom 2212 is an arc surface, and the cross-sectional profile of the outer surface S of the bottle bottom 2212 gradually decreases in the direction from the bottle mouth end A1 towards the bottle bottom end A2. The flap body 33 further includes an arc surface 33e. The arc surface 33e is located on one side of the flap body 33 facing the central axis of the base 30. The arc surface 33e is connected to the first guiding surface 33c and the second guiding surface 33d. The arc surface 33e extends obliquely downward from the second end of the flap body 33 towards the central axis of the base 30, and the arc surface 33e fits against the bottom surface of the magnetic bead bottle 22. In this embodiment, by providing the arc surface 33e on the flap body 33 to match the arc-shaped bottom surface of the magnetic bead bottle 22, the fitting degree between the bottom surface of the magnetic bead bottle 22 and the base 30 can be improved, so that the magnetic bead bottle 22 can be stably clamped on the base 30.

[0038] As Figure 4 shown, in one embodiment, the first guiding surface 33c, the second guiding surface 33d, and the arc surface 33e are connected at the second end of the flap body 33, so that the second end of the flap body 33 is in a pointed shape.

[0039] As Figure 7 and Figure 8 shown, in one embodiment, the reagent container 21 is provided with a guiding protrusion 212, and the magnetic bead bottle 22 is provided with a guiding slot 225. The guiding protrusion 212 is embedded in the guiding slot 225. When the guiding protrusion 212 is embedded in the guiding slot 225, the positioning protrusion 2231 is embedded in the positioning slot 311. That is, the cooperation between the guiding protrusion 212 and the guiding slot 225 can guide the clamping of the positioning protrusion 2231 and the positioning slot 311. In actual use, the operator can first position and install the magnetic bead bottle 22 on the reagent container 21 in such a way that the positioning protrusion 2231 is embedded in the positioning slot 311, and then place the reagent container 21 in the reagent position 11 of the reagent carrying assembly 10. The positioning protrusion 2231 on the magnetic bead bottle 22 can automatically be embedded in the positioning slot 311 on the base 30. Of course, it is not limited to the above installation method. In other embodiments, the operator can first place the reagent container 21 in the reagent position 11 of the reagent carrying assembly 10, and then place the magnetic bead bottle 22 in the accommodation hole 211 of the reagent container 21 in such a way that the positioning protrusion 2231 is embedded in the positioning slot 311. The positioning protrusion 2231 on the magnetic bead bottle 22 is automatically embedded in the positioning slot 311 on the base 30. In this embodiment, the installation difficulty between the magnetic bead bottle 22 and the base 30 can be reduced. It should be noted that the positions of the guiding protrusion 212 and the guiding slot 225 can be interchanged, that is, the guiding protrusion 212 can be provided on the magnetic bead bottle 22, and the guiding slot 225 can be provided on the reagent container 21, which can be determined according to actual design requirements.

[0040] As Figure 7 and Figure 8 shown, in one embodiment, the guiding slot 225 includes a first end face 2251 and a second end face 2252 in the rotation direction of the magnetic bead bottle 22, and there are gaps between the guiding protrusion 212 and the first end face 2251 and between the guiding protrusion 212 and the second end face 2252. Due to possible errors in the actual manufacturing and assembly of parts, the position where the positioning protrusion 2231 is engaged with the positioning slot 311 may not correspond to the position where the guiding protrusion 212 is engaged with the guiding slot 225, that is, when the guiding protrusion 212 is engaged in the guiding slot 225, the positioning protrusion 2231 does not engage into the positioning slot 311. In this embodiment, by providing gaps between the guiding protrusion 212 and the first end face 2251 and between the guiding protrusion 212 and the second end face 2252, that is, in the rotation direction of the magnetic bead bottle 22, the width of the guiding slot 225 is greater than the width of the guiding protrusion 212. In this way, the influence of errors existing in the actual manufacturing and assembly of parts can be eliminated, and even if there are errors in the actual manufacturing and assembly of parts, the positioning protrusion 2231 can engage into the positioning slot 311.

[0041] As Figure 4 , Figure 7 and Figure 8As shown, in one embodiment, the valve body 33 includes a first end and a second end opposite to the first end. The first end of the valve body 33 is connected to the base body 32. The valve body 33 further includes a first guiding surface 33c and a second guiding surface 33d. The first guiding surface 33c extends obliquely from the second end of the valve body 33 towards the base body 32 and one of the two valve bodies 33 adjacent to the valve body 33. The second guiding surface 33d extends obliquely from the second end of the valve body 33 towards the base body 32 and the other of the two valve bodies 33 adjacent to the valve body 33. The rotation angle of the magnetic bead bottle 22 corresponding to the gap is the first angle. The valve body 33 includes a first side surface 33a and a second side surface 33b in the rotation direction of the base 30. The extended surfaces of the first side surface 33a and the second side surface 33b intersect at the central axis of the base 30. The included angle between the first side surface 33a and the second side surface 33b is the second angle. Wherein, the first angle is less than one-half of the second angle. Wherein, the rotation angle of the magnetic bead bottle 22 corresponding to the gap refers to the angle that the magnetic bead bottle 22 rotates when the first end face 2251 or the second end face 2252 abuts against the guiding protrusion 212. In this embodiment, by defining that the first angle is less than one-half of the second angle, thus, as long as the guiding protrusion 212 is clamped in the guiding slot 225, the positioning protrusion 2231 of the magnetic bead bottle 22 will surely fall into the positioning slot 311, or fall onto the first guiding surface 33c, or fall onto the second guiding surface 33d. For the case where the guiding protrusion 212 falls onto the first guiding surface 33c or the second guiding surface 33d, under the action of the gravity of the magnetic bead bottle 22, it can finally slide into the positioning slot 311 along the first guiding surface 33c or the second guiding surface 33d.

[0042] As Figure 7 and Figure 8 shown, in one embodiment, the reagent container 21 includes a first side and a second side opposite to the first side in the first direction. The first direction is the inserting direction of the magnetic bead bottle 22 into the accommodating hole 211. The guiding protrusion 212 is provided on the first side of the reagent container 21. The magnetic bead bottle 22 further includes a supporting portion 226. The supporting portion 226 is provided on the outer side wall of the bottle body 221. The magnetic bead bottle 22 is clamped on the first side of the reagent container 21 through the supporting portion 226. Part of the edge of the supporting portion 226 is recessed towards the bottle body 221 to form a guiding slot 225.

[0043] As Figure 5 and Figure 6As shown, in one embodiment, the bottle body 221 of the magnetic bead bottle 22 further includes an annular support portion 2213. The annular support portion 2213 is provided at the bottom of the bottle body 221, and a plurality of rib plates 224 are located inside the annular support portion 2213. When the positioning protrusion 2231 is embedded in the positioning card slot 311, the flap body 33 is located inside the annular support portion 2213. In this embodiment, under the restriction of the annular support portion 2213, relative movement between the base 30 and the magnetic bead bottle 22 in the radial direction can be avoided, so that the magnetic bead bottle 22 can be stably clamped on the base 30.

[0044] In one embodiment, the sample analyzer 100 further includes a rotation driving assembly (not shown in the figure). The rotation driving assembly is connected to the base 30 and is used to drive the base 30 to rotate to mix the magnetic bead reagent contained in the magnetic bead bottle 22. The rotation driving assembly can be, but is not limited to, a driving method of a motor cooperating with a conveyor belt assembly or a motor cooperating with a gear assembly. Taking the motor cooperating with the conveyor belt assembly as an example, a driven wheel is installed at the bottom of each base 30, the driving wheel is installed on the output shaft of the motor, and the transmission belt surrounds the driving wheel and all the driven wheels. When the motor runs, all the driven wheels are driven to rotate through the driving wheel and the transmission belt, so as to mix the magnetic bead reagent in the magnetic bead bottle 22.

[0045] In one embodiment, the sample analyzer 100 further includes a lifting mechanism (not shown in the figure). The lifting mechanism is connected to the base 30 and is used to drive the base 30 to rise to lift the magnetic bead bottle 22. It should be noted that the connection between the lifting mechanism and the base 30 can be a direct connection to the base 30 or an indirect connection to the base 30. For example, the rotation driving assembly and the base 30 are installed on a bracket, the lifting mechanism is connected to the bracket, and the lifting mechanism indirectly drives the base 30 to rise by driving the bracket to rise. In this embodiment, by providing the lifting mechanism to drive the base 30 to rise, when it is necessary to mix the magnetic bead reagent in the magnetic bead bottle 22, the base 30 can be driven to rise by the lifting mechanism to lift the magnetic bead bottle 22 first, so that the guiding card slot 225 on the magnetic bead bottle 22 is disengaged from the restriction of the guiding protrusion 212 on the reagent container 21, so that the subsequent rotation of the magnetic bead bottle 22 can proceed smoothly.

[0046] As Figures 1 to 8As shown in the figure, an embodiment of the present invention further provides a sample analyzer 100. The provided sample analyzer 100 includes a reagent carrier assembly 10, a base 30, and an open lid assembly 40. The reagent carrier assembly 10 is provided with a plurality of reagent positions 11.

Among them, the magnetic bead bottle 22 is provided with a first positioning member 223, and the base 30 is provided with a second positioning member 31. The first positioning member 223 and the second positioning member 31 are clamped to make the magnetic bead bottle 22 contained in the containing hole 211 be non-rotatably clamped to the base 30.

[0047] In one embodiment, the second positioning member 31 is a positioning slot 311 arranged on the base 30. The base 30 includes a base body 32 and a plurality of lobes 33 connected to the base body 32. The plurality of lobes 33 are distributed around the central axis of the base 30 and are spaced apart from each other. The gap between two adjacent lobes 33 forms the positioning slot 311.

[0048] In one embodiment, the lobe 33 includes a first end and a second end opposite to the first end. The first end of the lobe 33 is connected to the base body 32. The lobe 33 includes a first side surface 33a and a second side surface 33b in the rotation direction of the base 30. Among two adjacent lobes 33, the gap between the first side surface 33a of one lobe 33 and the second side surface 33b of the other lobe 33 forms the positioning slot 311. The lobe 33 further includes a first guiding surface 33c and a second guiding surface 33d. The first guiding surface 33c extends obliquely from the second end of the lobe 33 towards the base body 32 to be connected to the first side surface 33a, and the second guiding surface 33d extends obliquely from the second end of the lobe 33 towards the base body 32 to be connected to the second side surface 33b.

[0049] In one embodiment, the lobe 33 further includes an arc surface 33e. The arc surface 33e is located on the side of the lobe 33 facing the central axis of the base 30. The arc surface 33e is connected to the first guiding surface 33c and the second guiding surface 33d. The arc surface 33e extends obliquely downward from the second end of the lobe 33 towards the central axis of the base 30.

[0050] In one embodiment, the sample analyzer 100 further includes a rotation drive assembly. The rotation drive assembly is connected to the base 30. The rotation drive assembly is used to drive the base 30 to rotate to mix the magnetic bead reagent contained in the magnetic bead bottle 22.

[0051] In one embodiment, the sample analyzer 100 further includes a lifting mechanism, which is connected to the base 30 and is used to drive the base 30 to rise so as to lift the magnetic bead bottle 22.

[0052] For the effective effect of the solution adopted by the sample analyzer 100 proposed in this embodiment, the structures and connection relationships of other components can refer to all the above embodiments and will not be elaborated here.

[0053] As Figure 3 、 Figures 5 to 8 shown, an embodiment of the present invention further provides a set of 20 reagent containers 21. The set of 20 reagent containers 21 includes a reagent container 21 and a magnetic bead bottle 22. The reagent container 21 is provided with a receiving hole 211. The magnetic bead bottle 22 includes a bottle body 221 and a bottle cap 222 rotatably connected to the bottle body 221. The bottle body 221 is rotatably disposed in the receiving hole 211.

Among them, one of the reagent container 21 and the magnetic bead bottle 22 is provided with a guiding protrusion 212, and the other of the reagent container 21 and the magnetic bead bottle 22 is provided with a guiding slot 225. The guiding protrusion 212 is embedded in the guiding slot 225. When the guiding protrusion 212 is embedded in the guiding slot 225, the positioning protrusion 2231 is embedded in the positioning slot 311.

[0054] In one embodiment, the guiding slot 225 includes a first end face 2251 and a second end face 2252 in the rotation direction of the magnetic bead bottle 22, and there are gaps between the limiting protrusion and the first end face 2251 and between the limiting protrusion and the second end face 2252.

The first direction is the inserting direction for the magnetic bead bottle 22 to be inserted into the receiving hole 211, and the limiting protrusion is provided on the first side of the reagent container 21. The magnetic bead bottle 22 further includes a supporting portion 226, and the supporting portion 226 is provided on the outer side wall of the bottle body 221.
