Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to a microbial detector. Background Art

[0002] A microbial detector is a device used to culture microorganisms and detect the cultured microorganisms. Currently, there are some fully automated microbial detectors. Users place a sample container loaded with a growth medium and a sample on the sample loading mechanism of the microbial detector, and the sample loading mechanism automatically transfers the sample container into the device for subsequent incubation, detection, etc. In related technologies, users usually place the sample containers on the sample loading mechanism in a disorderly manner. Therefore, the microbial detector also needs to be provided with a sorting mechanism for sorting the sample containers, which increases the cost and volume of the sample loading module. In addition, currently, the microbial detector usually uses a conveyor belt as the sample loading mechanism, and the sample containers are freely placed on the conveyor belt and are prone to tipping due to collision and vibration during transportation, thereby causing blockage of the sample loading mechanism. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a microbial detector that can achieve orderly placement of sample containers during the sample loading process and reduce the collision between sample containers during the sample loading process.

[0004] According to the microbial detector in an embodiment of the present invention, it includes:

[0005] A housing assembly;

[0006] A sample loading assembly, including a carrying member that can move relative to the housing assembly. The carrying member is used to receive a sample container loaded with a sample and a growth medium. Among them, the carrying member has a plurality of accommodating structures that are spaced apart and used to accommodate the sample container, so as to transport the received sample container into the housing assembly when the carrying member moves relative to the housing assembly;

[0007] A transfer assembly for transferring the sample container from the carrying member in the housing assembly;

[0008] An incubation assembly for receiving the sample container transferred by the transfer assembly and incubating the sample in the sample container;

[0010] A controller configured to output a detection result of the growth condition of microorganisms in the sample container according to the feedback information of the detection assembly.

[0011] The sample extraction device according to an embodiment of the present invention has at least the following beneficial effects:

[0012] The carrying member carries the sample container through the accommodating structures arranged at intervals. When the user places the sample container into the accommodating structures within the carrying member, the sample containers are sorted. Therefore, there is no need to set an additional sorting mechanism in the loading assembly, which can reduce the cost and volume of the loading assembly. On the other hand, the accommodating structures can accommodate the sample containers to position them, thereby reducing the mutual collision of the sample containers, further reducing the tipping of the sample containers, and ensuring the normal progress of the loading process.

[0013] In other embodiments of the present invention, the accommodating structures are further configured to: during the movement of the carrying member relative to the housing assembly, at least restrict the relative movement in the horizontal direction between the sample container and the carrying member.

[0090] The present invention provides a microbial detector, which can culture microorganisms and detect the culture conditions of microorganisms. Referring to Figures 1 to 3 , respectively show the three-dimensional schematic diagrams of the microbial detector in different directions in the first embodiment of the present invention, and the three-dimensional schematic diagram after hiding the housing assembly 400. As shown in the figure, the microbial detector in this embodiment includes a sample loading assembly 100, a transfer assembly 200, an incubation assembly 300, a housing assembly 400, a detection assembly and a controller. For the convenience of understanding, first, the components of the microbial detector and its main working modes will be described.

[0091] The sample loading assembly 100 is used to receive the sample container 10, and the sample container 10 is loaded with a sample and a growth medium. The housing assembly 400 defines an inner cavity, and the sample loading assembly 100, the transfer assembly 200, the incubation assembly 300, the detection assembly, the controller, etc. are all located inside the housing assembly 400. In some embodiments, the inner cavity of the housing assembly 400 includes a sample loading cavity and an incubation cavity that communicate with each other. On the one hand, the housing assembly 400 can play a role in safety protection. On the other hand, the housing assembly 400 also helps to maintain an environment suitable for the growth of microorganisms inside it (such as the incubation cavity).

[0092] The transfer assembly 200 is used to transfer the sample container 10. For example, it transfers the sample container 10 from the sample loading assembly 100 to the incubation assembly 300, or transfers the tested sample container 10 from the incubation assembly 300 to the positive container storage assembly 600 or the negative container storage assembly 700. In some embodiments, the transfer assembly 200 includes a manipulator and a motion mechanism for driving the manipulator to move in three-dimensional space. The manipulator is used to hold the sample container 10, and the motion mechanism includes a moving power mechanism for driving the manipulator to move along the X-axis, Y-axis, and Z-axis. In other embodiments, the motion mechanism may further include a rotational power mechanism for driving the manipulator to rotate around a horizontal axis so that the sample container 10 rotates from a vertical posture to a horizontal posture. In Figures 1 to 3 In the illustrated embodiment, the transfer assembly 200 includes the aforementioned manipulator, moving power mechanism, and rotational power mechanism.

[0093] The incubation assembly 300 is located in the incubation cavity of the housing assembly 400 and is used to receive the sample container 10 transferred by the transfer assembly 200, so that the sample in the sample container 10 is incubated in the incubation cavity. In some embodiments, the incubation assembly 300 includes a plurality of incubation slots. One end of the incubation slot is an inlet for inserting the sample container 10, and the other end is a detection port for the detection assembly to detect the growth of microorganisms in the sample container 10. The sample container 10 is placed horizontally in the incubation slot, and its bottom faces the detection port. In other embodiments, the incubation assembly 300 may further be provided with a mixing mechanism, and the mixing mechanism can drive the sample container 10 to move, so that the sample and the growth medium in the sample container 10 are fully mixed. In some specific embodiments, the incubation assembly 300 includes an incubation rack, an incubation seat, and an incubation driving mechanism. A plurality of incubation slots are provided on the incubation seat. The incubation seat is rotatably connected to the incubation rack through a horizontally arranged rotating shaft, and the incubation driving mechanism can drive the incubation seat to swing back and forth around the rotating shaft, so as to realize the batch mixing of a plurality of sample containers 10.

[0094] The detection component is used to detect the growth of microorganisms in the sample container 10 placed in the incubation component 300, so that the controller can judge whether the growth of microorganisms meets the standard based on the detection results of the detection component. In some embodiments, the detection component performs detection based on the colorimetric method. For example, a color-developing element is provided inside the sample container 10 (specifically, at its bottom), and the color-developing element changes color according to the growth of microorganisms in the sample container 10. The detection component can detect the growth of microorganisms by detecting the color change of the color-developing element. In other embodiments, the detection component can also detect based on the fluorescence of microorganisms.

[0095] In addition to the above components, in some embodiments, the microorganism detector may further include a positive container storage component 600 and a negative container storage component 700. Among them, the positive container storage component 600 is used to recycle positive containers (that is, the sample containers 10 in which the growth of microorganisms meets the standard), and the positive containers in the positive container storage component 600 will be taken away by the user for further cultivation. The negative container storage component 700 is used to recycle negative containers (that is, the sample containers 10 in which the growth of microorganisms does not grow or does not meet the standard), and the negative containers in the negative container storage component 700 will be taken away and discarded by the user. Figures 1 to 3 For example, the housing component 400 is respectively provided with a second window 420 and a third window 430 corresponding to the positive container storage component 600 and the negative container storage component 700. Both the second window 420 and the third window 430 are closed by covers, and the corresponding covers can be opened to take away the positive container or the negative container.

[0096] A typical microorganism detection process is described in combination with the above structure: The user sends the sample container 10 into the loading component 100, and the transfer component 200 transfers the loading component 100 into the incubation component 300 for incubation. After incubation, the detection component detects the growth of microorganisms in the sample container 10 in the incubation component 300. For positive containers, the transfer component 200 transfers the positive containers from the incubation component 300 to the positive container storage component 600. For negative containers, the transfer component 200 transfers the negative containers from the incubation component 300 to the negative container storage component 700.

[0097] In the related art, the loading component of the microbial detector usually uses a conveyor belt as a loading mechanism. The user places the sample container 10 on the conveyor belt in disorder. The conveyor belt transfers the sample container 10 to the sorting mechanism for sorting. The sorted sample container 10 is then transferred to the incubation component by the transfer component. However, this method requires the provision of a sorting mechanism for sorting the sample containers 10, which increases the cost and volume of the loading component. In addition, the sample container 10 is freely placed on the conveyor belt, which is prone to tipping over due to collision and vibration during transportation, thereby causing blockage of the loading mechanism. Based on this, the present embodiment proposes a sample analyzer that does not require the provision of an additional sorting mechanism, can reduce the cost and volume of the loading component, and can also reduce the tipping over of the sample container 10, thereby ensuring the normal progress of the loading process.

[0098] Reference Figure 1 , Figure 2 The sample loading component 100 in this embodiment includes a carrying component 110, and the carrying component 110 can move relative to the housing component 400 to receive the sample container 10. In different embodiments, the carrying component 110 can have different shapes and movement modes. For example, the carrying component 110 can move in a straight line, or the carrying component 110 can be a chain structure, which will be explained in conjunction with different embodiments later.

[0099] The supporting component 110 can accept a sample container 10 loaded with a sample and a growth medium. Specifically, the supporting component 110 has a plurality of spaced-apart accommodating structures, and the accommodating structures are used to accommodate the sample containers 10. In this way, the user has sorted the sample containers 10 when placing them in the accommodating structures in the supporting component 110. Therefore, there is no need to provide an additional sorting mechanism in the sample loading component, which can reduce the cost and volume of the sample loading component. On the other hand, the accommodating structure can accommodate the sample containers 10 to position them, thereby reducing collisions between the sample containers 10, thereby reducing the tipping over of the sample containers 10 and ensuring the normal progress of the sample loading process.

[0100] On the basis of the first embodiment, in some embodiments of the present invention, during the movement of the carrying component 110 relative to the housing assembly 400, the accommodating structure can at least limit the relative movement between the sample container 10 and the carrying component 110 in the horizontal direction. In a common sample loading scenario, multiple sample containers 10 are placed on the carrying component 110 in the horizontal direction. Therefore, by limiting the displacement of the sample container 10 in the horizontal direction, the collision between the sample containers 10 can be reduced. In other embodiments, the accommodating structure can also limit the displacement of the sample container 10 in the vertical direction, for example, limiting the displacement of the sample container 10 upward to separate from the carrying component 110, so that the sample container 10 can be placed on the carrying component 110 more stably.

[0101] It should be noted that when the carrying member 110 is stationary relative to the housing assembly 400, the accommodating structure can also limit the relative movement between the sample container 10 and the carrying member 110 in the horizontal direction.

[0102] When the accommodating structure can at least limit the relative movement between the sample container 10 and the carrying member 110 in the horizontal direction, in some embodiments of the present invention, the accommodating structure includes a carrying portion and a positioning portion. The carrying portion is used to carry the bottom wall of the sample container 10, and the positioning portion is used to cooperate with the side wall of the sample container 10 to limit the relative movement between the sample container 10 and the carrying member in the horizontal direction. That is, this embodiment is applicable to the case where the sample container 10 is placed vertically. In some specific embodiments, when the sample container 10 is placed in the accommodating structure, the positioning portion remains in contact with the side wall of the sample container 10 for positioning. In other specific embodiments, when the sample container 10 is placed in the accommodating structure, there may be a certain gap between the positioning portion and the side wall of the sample container 10. When the sample container 10 moves or topples to a certain extent in the accommodating structure and then comes into contact with the positioning portion for positioning.

[0103] In other embodiments, the accommodating structure includes a carrying and positioning portion. The carrying and positioning portion is used to carry the side wall of the sample container 10 and cooperate with the side wall of the sample container 10 to limit the relative movement between the sample container 10 and the carrying member in the horizontal direction. That is, this embodiment is applicable to the case where the sample container 10 is placed horizontally. When the sample container 10 is also placed in the incubation assembly 300 in a horizontal posture, compared with the foregoing embodiment, this embodiment can omit the step of the transfer assembly 200 adjusting the sample container 10 from a vertical posture to a horizontal posture. In this embodiment, the accommodating structure is provided with a groove that coincides with the outer contour of the sample container 10 in a horizontal posture, and the sample container 10 can be inserted into the groove. In addition, the accommodating structure can also be an annular clamp. The axis of the clamp is parallel to the horizontal direction. When the sample container 10 is inserted into the clamp, the clamp can hold the sample container 10 tightly, thereby realizing the positioning of the sample container 10.

[0104] When the accommodating structure includes a carrying portion and a positioning portion, in some embodiments of the present invention, the carrying portion and the positioning portion together form an accommodating space for accommodating the sample container 10. Among them, the carrying portion defines the bottom of the accommodating space, and the positioning portion defines the side portion of the accommodating space. Thus, when the sample container 10 is placed in the accommodating structure, the carrying portion carries the bottom of the sample container 10, and the positioning portion cooperates with the side wall of the sample container 10 for positioning.

[0105] When the accommodating structure includes a carrying and positioning portion, in some embodiments of the present invention, the carrying and positioning portion itself forms an accommodating space for accommodating the sample container 10. For example, the carrying and positioning portion is the inner wall surface of the groove that coincides with the outer contour of the sample container 10, or the inner wall surface of the foregoing annular clamp.

[0106] When the bearing part and the positioning part together form a receiving space for receiving the sample container 10, in some embodiments of the present invention, the bearing member 110 includes at least one substrate 1111 for setting the receiving structure, and the receiving space is recessed relative to the substrate 1111. For example, the bearing member 110 includes at least one bearing seat 111, and the bearing seat 111 can be Figure 4 the rectangular seat body shown, or can be Figure 17 the smallest unit of the chain structure shown in. The bearing seat includes a substrate 1111, and the substrate is provided with a receiving structure. In some embodiments, the receiving structure is a placement hole 1115 formed by recessing from the upper side surface of the substrate 1111. At this time, the bearing part includes the bottom wall surface of the placement hole 1115, and the positioning part includes the side wall surface of the placement hole 1115. When the sample container 10 is inserted into the placement hole 1115, the bottom wall of the placement hole 1115 bears the sample container 10, and the side wall can abut against the outer side wall of the sample container 10, so that the sample container 10 is held in the placement hole 1115. Refer to Figure 4 , the bearing member 110 includes two bearing seats 111, and a plurality of spaced-apart placement holes 1115 are provided on each bearing seat 111, and the plurality of placement holes 1115 can be arranged in an array, for example, arranged in a rectangular array.

[0107] When the bearing part and the positioning part together form a receiving space for receiving the sample container 10, in some embodiments of the present invention, the bearing member 110 includes at least one substrate 1111 for setting the receiving structure, and the receiving space protrudes relative to the substrate 1111. Specifically, the receiving structure includes at least a part of the substrate 1111 and a protruding part 1112, and the protruding part 1112 protrudes relative to the substrate 1111. At this time, the bearing part includes the surface of the substrate 1111 that defines the receiving space with the protruding part 1112, and the positioning part includes the surface of the protruding part 1112 that defines the receiving space with the substrate 1111. When the sample container 10 is placed on the substrate 1111, the protruding part 1112 can cooperate with the side surface of the sample container 10 to limit the horizontal movement of the sample container 10 relative to the bearing seat 111. For example, refer to Figure 15 , the bearing member 110 includes a plurality of bearing seats 111 forming a chain structure, and each bearing seat 111 is provided with a substrate 1111 and a protruding part 1112. The protruding part 1112 is an annular side plate extending from the upper side surface of the substrate 1111. Among them, the annular side plate can be closed in the circumferential direction or can be provided with a notch (for example Figure 17 shown). In other embodiments, a plurality of protruding parts 1112 for positioning a single sample container 10 are provided, and the plurality of protruding parts 1112 are spaced apart along the circumference of the sample container 10. More specifically, the protruding part 1112 can be provided as an elastic structure.

[0108] It should be noted that the above examples respectively illustrate different forms of the bearing part and the positioning part by Figure 4 and Figure 17 However, it does not represent a limitation thereto. For example, Figure 4 the carrier base 111 in Figure 17 the carrier base 111 in Figure 20 may also be provided with a placement hole 1115, as shown in, for example

[0109] It should also be noted that when the carrier base 111 is the smallest unit of a chain structure as shown in Figure 15 multiple accommodating structures may also be provided on the carrier base 111. For example, multiple Figure 15 annular side plates as shown in

[0110] are provided on the carrier base 111, and each annular side plate is used for positioning a single sample container 10. At this time, the multiple base plates 1111 corresponding to the multiple annular side plates may be connected into an integral structure to form an integral base plate.

[0111] When the carrier positioning part itself forms an accommodating space for accommodating the sample container 10, in some embodiments of the present invention, the carrier member 110 includes at least one base plate 1111 for setting the accommodating structure, and the accommodating space is concave relative to the base plate 1111. For example, the accommodating structure is the groove that matches the outer contour of the sample container 10 described above, and the carrier positioning part is the inner wall surface of the groove.

[0112] Based on the first embodiment, in some embodiments of the present invention, the carrier member 110 is configured to be able to move linearly relative to the housing assembly 400, so as to transfer the sample container 10 input by the user into the housing assembly 400.

[0113] Specifically, referring to Figure 1 and Figure 2 , the carrier member 110 can linearly move relative to the housing assembly 400 in a first direction to switch between an extended position and a retracted position. When it is in the extended position, at least part of the carrier member 110 extends outside the housing assembly 400 for the user to place the sample container 10. When it is in the retracted position, the carrier member 110 is located inside the housing assembly 400. In this way, the carrier member 110 can be hidden, reducing the risk of damage and contamination of the carrier member 110.

[0114] Based on the above, the detection process of microorganisms in this embodiment includes: the supporting component 110 moves to the extended position to receive the sample container 10, and after receiving the sample container 10, the supporting component 110 moves to the retracted position, and the transfer component 200 transfers the sample container 10 in the supporting component 110 in the retracted position to the incubation component 300 for incubation. After the incubation is completed, the detection component detects the growth of microorganisms in the sample container 10 that has completed incubation.

[0115] The supporting component 110 in this embodiment can move in a straight line direction, and its moving stroke is short, which helps to reduce the volume of the microorganism detector and helps the supporting component 110 to quickly reach the extended position or the retracted position. Figure 1 , Figure 2 As shown in the example, the first direction is the front-to-back direction in the figure (the front side refers to the side of the housing assembly 400 having the human-computer interaction channel opening).

[0116] It should be noted that, in some specific embodiments, the first direction is a horizontal direction, more specifically Figure 1 , Figure 2 The front-to-back direction.

[0117] When the bearing member 110 is capable of moving along the first direction, in some embodiments of the present invention, the housing assembly 400 has a transfer area therein. Figure 8 , Figure 9 The approximate range of the transfer area is exemplarily indicated by a dotted frame, wherein the transfer area refers to an area in which the transfer component 200 can obtain the sample container 10 in the supporting component 110 that enters the housing component 400. The size and position of the transfer area are not limited in this embodiment. In some compact microbiological detectors, the internal space is limited, resulting in a limited range of motion of the transfer component 200. Thus, when the supporting component 110 moves to the retracted position along the first direction, only some of the multiple containing structures are located in the transfer area, and the transfer component 200 can only transfer the sample container 10 in the containing structure located in the transfer area to the incubation component 300. In other words, when the range of motion of the transfer component 200 is limited, if the supporting component 110 has a large number of containing structures, the transfer component 200 can only obtain the sample container 10 in some of the containing structures. For example, in Figure 4 In the embodiment, when the bearing member 110 is in the retracted position, only the accommodating structure in the left area is located in the transfer area, and the accommodating structure in the right area is located outside the transfer area; for example, in Figure 4 In the embodiment, when the carrying component 110 is in the retracted position, the accommodating structure in the middle area is located in the transfer area, and the accommodating structure in the left area and the accommodating structure in the right area are located outside the transfer area.

[0118] Based on the above, the bearing component 110 of the present embodiment is further configured to be able to move at least between the retracted position and the first position along a second direction intersecting the first direction, and the bearing component 110 has at least a first area and a second area arranged along the second direction, and the first area and the second area are both provided with at least one accommodating structure, wherein the first area and the second area are different but may have a common area, in other words, the first area and the second area do not overlap at all, or the first area and the second area have a partially overlapping area, and some accommodating structures can be considered to be in the first area or in the second area, for example Figure 9 shown.

[0119] When the carrying component 110 is located at the first position, the transfer component 200 can transfer the sample container 10 from the accommodating structure in the first area. When the carrying component 110 is located at the retracted position, the transfer component 200 can transfer the sample container 10 from the accommodating structure in the second area. That is, by moving the carrying component 110 along the second direction, the accommodating structures in different areas of the carrying component 110 can be located in the transfer area respectively, so that the transfer component 200 can obtain the accommodating structures in all areas of the sample loading component 100. For example, Figure 8 In the figure, the carrying component 110 includes a first area and a second area. The figure exemplarily divides the first area to the second area by a vertical dotted line, the right side is the first area, and the left side is the second area. The carrying component 110 can move between the first position and the retracted position. When the carrying component 110 is in the retracted position, the accommodating structure in the second area is located in the transfer area, and the accommodating structure in the first area is located outside the transfer area. When the transfer component 200 moves all the sample containers 10 in the second area out, the carrying component 110 moves from the retracted position to the first position in the left direction, so that the accommodating structure in the first area is located in the transfer area, and the transfer component 200 then moves all the sample containers 10 in the first area out; for another example, Figure 9In the figure, the supporting component 110 includes a first area, a second area and a third area, the first area is on the right, the second area is in the middle, and the third area is on the left. The figure exemplarily divides the first area to the third area by vertical dotted lines. The supporting component 110 can move between a first position, a retracted position and a second position. When the supporting component 110 is in the retracted position, the accommodating structure of the second area is located in the transfer area, and the accommodating structures of the first area and the third area are located outside the transfer area. When the transfer component 200 moves out all the sample containers 10 in the second area, the supporting component 110 first moves from the retracted position to the first position in a left direction so that the accommodating structure of the first area on the right is located within the transfer area. After the transfer component 200 moves out all the sample containers 10 in the first area, the supporting component 110 moves from the first position to the second position in a right direction so that the accommodating structure of the third area on the left is located within the transfer area. The transfer component 200 then moves out all the sample containers 10 in the third area.

[0120] It should be noted that, in some specific embodiments, the second direction is perpendicular to the first direction, and both are horizontal directions.

[0121] When the carrying member 110 is capable of moving along the first direction, in some specific embodiments, referring to Figure 3 The incubation components 300 are arranged in two groups, along the second direction (eg Figure 3 The two groups of incubation components 300 are arranged side by side and spaced apart, and an entrance to the incubation tank is provided on one side of the two groups of incubation components 300 that are opposite to each other, and the transfer component 200 is located between the two groups of incubation components 300, so as to facilitate the selective delivery of the sample container 10 into the incubation components 300 on both sides.

[0122] It should be noted that since the transfer component 200 is located between the two groups of incubation components 300, the maximum stroke of the transfer component 200 along the second direction will be limited by the incubation components 300 on both sides. In order to be able to carry more sample containers 10 at one time, the sample loading component 100 of this embodiment has more accommodating structures. Specifically, the maximum spacing between the accommodating structures on the sample loading component 100 along the second direction is longer than the maximum stroke of the transfer component 200 along the second direction, that is, the length of the transfer area along the second direction. At this time, the transfer component 200 can be moved along the second direction by the carrying component 110 to obtain the sample containers 10 in the accommodating structures in each area on the sample loading component 100.

[0123] When the carrying member 110 is capable of moving in the first direction, in some embodiments of the present invention, a plurality of carrying members 110 are provided. For example, the carrying members 110 are provided as two, three, four, etc. Each carrying member 110 is configured to move independently relative to the housing assembly 400, so that when at least one carrying member 110 is in the retracted position, at least another carrying member 110 can be in the extended position. Thus, when the user loads a sample onto one of the carrying members 110, the transfer assembly 200 can transfer the sample container 10 from other carrying members 110 in the retracted position, thereby reducing the waiting time of the transfer assembly 200 and helping to improve efficiency.

[0124] When the carrying member 110 is capable of moving in the first direction, in some embodiments of the present invention, referring to Figure 1 , Figure 2 , the housing assembly 400 has a first channel opening 410, and the shape and size of the first channel opening 410 are adapted to allow the carrying member 110 to extend or enter the housing assembly 400. For example, the first channel opening 410 is a rectangular channel opening. In this embodiment, when the carrying member 110 is in the retracted position, the sample loading assembly 100 closes the first channel opening 410. Thus, on the one hand, it can further enhance the safety protection of the carrying member 110 and reduce the pollution of the carrying member 110 and other internal structures by external pollution sources. On the other hand, it can also increase the heat preservation performance of the housing assembly 400, reduce the temperature fluctuation inside the housing assembly 400, and is conducive to forming a temperature-stable incubation environment.

[0125] Specifically, the sample loading assembly 100 has a blocking structure for closing the first channel opening 410. For example Figures 1 to 4 the shown cover. Among them, the blocking structure can be provided on the carrying member 110 or on other components of the sample loading assembly 100. For example Figure 4 in, the blocking structure is provided on the sliding seat for realizing the sliding of the carrying member 110.

[0126] It should be noted that in some specific embodiments, the size of the blocking structure is slightly smaller than the size of the first channel opening 410. When the blocking structure closes the first channel opening 410, it is embedded in the first channel opening 410; in other specific embodiments, the size of the blocking structure is larger than the size of the first channel opening 410. When the blocking structure closes the first channel opening 410, it fits with the outer surface of the housing assembly 400 and covers the edge of the first channel opening 410.

[0127] In some other embodiments of the present invention, the housing assembly 400 includes a housing having a first channel opening 410, the shape of the first channel opening 410 being larger than and adapted to allow the loading member 110 to extend out of or enter the housing assembly 400. For example, the first channel opening 410 is a rectangular channel opening. In this embodiment, the housing assembly 400 further has a cover independently provided from the sample loading assembly 100, and the cover can move relative to the housing to open or close the first channel opening 410. When the loading member 110 is in the retracted position, the cover closes the first channel opening 410, which can also achieve effects such as enhancing safety protection, reducing external contamination, and enhancing heat preservation performance.

[0128] It should be noted that the cover in this embodiment can rotate relative to the housing to open or close the first channel opening 410, or can move relative to the housing to open or close the first channel opening 410.

[0129] It should also be noted that the cover in this embodiment can be manually opened or closed, or can be opened or closed by a driving mechanism.

[0130] When the loading member 110 can move in the first direction, in some embodiments of the present invention, referring to Figures 4 to 7 , the sample loading assembly 100 further includes a sliding mechanism 120. The sliding mechanism 120 includes a fixed member 121 connected to the housing assembly 400, and a sliding member 122 slidably connected to the fixed member 121. The loading member 110 is connected to the sliding member 122, thereby realizing the sliding of the loading member 110 relative to the housing assembly 400. In some specific embodiments, two fixed members 121 are provided, and the two fixed members 121 are arranged in parallel. In some specific embodiments, the sliding member 122 includes a first sliding seat 1221. The first sliding seat 1221 is connected to the fixed member 121 and can slide relative to the fixed member 121 in the first direction. The loading member 110 is connected to the first sliding seat 1221. For example, the fixed member 121 is provided with a first slide rail 123 extending in the first direction, and the first sliding seat 1221 is slidably connected to the first slide rail through a first slider 124. Specifically, Figure 5 、 Figure 6In [description], first slide rails 123 are provided on both side fixing members 121, and both ends of the first sliding seat 1221 are slidably connected to the first slide rails 123 on both sides through first sliders 124. In some other specific embodiments, the sliding member 122 includes a first sliding seat 1221 and a second sliding seat 1222. The first sliding seat 1221 can be understood as described above. The second sliding seat 1222 is connected to the first sliding seat 1221 and can slide relative to the first sliding seat 1221 in a second direction. The carrying member 110 is connected to the second sliding seat 1222, so that the carrying member 110 can slide in the first direction and the second direction. For example, the first sliding seat 1221 is provided with a second slide rail 125, and the second sliding seat 1222 is provided with second sliders (not shown). The second sliding seat 1222 is slidably connected to the second slide rail 125 through the second sliders. Specifically, in Figure 5 , Figure 6 In [description], a second slide rail 125 is provided on the upper side of the first sliding seat 1221, and second sliders are provided on the lower side of the second sliding seat 1222. It should be noted that, as Figures 4 to 7 shown, when the sliding member 122 includes a first sliding seat 1221 and a second sliding seat 1222, the second sliding seat 1222 has a vertical cover. When the carrying member 110 is in the retracted position, the vertical cover of the second sliding seat 1222 will close the first channel opening 410.

[0131] In this embodiment, the specific connection between the aforementioned carrying member 110 and the sliding member 122 means that the carrying member 110 and the sliding member 122 are detachably connected. In this way, when the user loads the sample, the carrying member 110 can be first transferred from the sliding member 122 to other positions convenient for loading the sample, and then the carrying member 110 is reinstalled on the sliding member 122 after loading the sample, making the user operation more flexible. In addition, it is also convenient to clean the carrying member 110. It should be noted that when the sliding member 122 includes the first sliding seat 1221, the carrying member 110 and the first sliding seat 1221 are detachably connected. When the sliding member 122 includes the first sliding seat 1221 and the second sliding seat 1222, the carrying member 110 and the second sliding seat 1222 are detachably connected.

[0132] It should be noted that the aforementioned detachable connection includes the case where the carrying member 110 and the sliding member 122 are locked through a locking mechanism. For example, the carrying member 110 and the sliding member 122 are provided with locking mechanisms such as mutually cooperating buckles, and also includes the case where the carrying member 110 is directly placed on the sliding member 122.

[0133] When the carrying member 110 is detachably connected to the sliding member 122, in some embodiments of the present invention, the carrying member 110 and the sliding member 122 are further provided with cooperating positioning portions. For example, one of the carrying member 110 and the sliding member 122 is provided with a positioning post, and the other is provided with a positioning hole. When the carrying member 110 is placed on the sliding member 122, the positioning post is inserted into the positioning hole to achieve positioning. Another example is that the sliding member 122 is provided with a positioning groove, and the carrying member 110 is integrally placed in the positioning groove, and positioning is achieved by the abutment between the outer side surface of the carrying member 110 and the groove wall of the positioning groove.

[0134] When the carrying member 110 is detachably connected to the sliding member 122, in some embodiments of the present invention, referring to Figures 7 to 11 , the carrying member 110 includes a carrying seat 111, and the carrying seat 111 includes a carrying body 112 and a handle 113. The carrying body 112 is used for placing the sample container 10, and the handle 113 is connected to the carrying body 112. The user can lift the carrying member 110 through the handle 113, so that the carrying member 110 is separated from the sliding member 122. It should be noted that the aforementioned substrate 1111 can be connected to the carrying body 112 as an independent element, or as a part of the carrying body 112.

[0135] The handle 113 includes a connecting portion 1131 rotatably connected to the carrying body 112, and a gripping portion 1132 for the user to grip. Specifically, the connecting portion 1131 includes a rotating shaft, and the handle 113 can rotate relative to the carrying body 112 between a lifted position and an initial placement position around the rotating shaft. In Figures 7 to 11 the shown embodiment, the handle 113 further includes two connecting arms 1133. The two connecting arms 1133 are respectively connected to opposite sides of the carrying body 112 through two connecting portions 1131, and the gripping portion 1132 is connected between the two connecting arms 1133, specifically connected to the ends of the connecting arms 1133. It should be noted that the present invention does not limit the specific shape of the handle 113. For example, the connecting arm 1133 can have a curved section or a bent section.

[0136] In this embodiment, the handle 113 can rotate upward relative to the carrying body 112 to the lifted position, that is, Figure 10 the position shown. After this position, the handle 113 cannot continue to rotate. When the handle 113 is in the lifted position, the gripping portion 1132 is higher than the connecting portion 1131, and the center of gravity A of the carrying body 112 (for easy understanding, the position of the center of gravity is indicated by a dotted circle in the figure) and the gripping portion 1132 are located on the same side of the connecting portion in the horizontal direction. Thus, when the user lifts the carrying member 110, the carrying body 112 can remain stable under the action of its own gravity, so as to Figure 10Taking the shown example, the center of gravity A and the holding part 1132 are both located on the right side of the connecting part 1131 in the horizontal direction. When the user lifts the handle 113, there is a tendency for the carrying body 112 to rotate to the right relative to the handle 113 under the action of its own gravity. However, since the handle 113 cannot continue to rotate in the lifting direction at the lifted position, the carrying body 112 will remain in the current position. If the carrying body 112 rotates to the left relative to the handle 113, it is necessary to overcome the gravity of the carrying body 112 itself, so that the carrying body 112 can be kept stable. In addition, after the user puts down the handle 113, the handle 113 can rotate downward to the retracted position under the action of its own gravity, without the user folding the handle 113, which is more convenient to use.

[0137] When the carrying component 110 includes the carrying body 112 and the handle 113, in some embodiments of the present invention, referring to Figure 10 , when the handle 113 is in the lifted position, both the connecting part 1131 and the holding part 1132 are located above the center of gravity A of the carrying body 112, which helps to shorten the length of the handle 113 and can enhance the stability of the carrying body 112 at the same time.

[0138] When the carrying component 110 includes the carrying body 112 and the handle 113, in some embodiments of the present invention, referring to Figure 11 , the handle 113 can also rotate downward relative to the carrying body 112 to the initial placement, and when the handle 113 is in the initial placement, the uppermost end of the handle 113 is not higher than the uppermost end of the carrying body 112, so as to reduce the overall height of the carrying component 110 and facilitate the carrying component 110 to enter and exit the chassis assembly 400.

[0139] When the carrying component 110 includes the carrying body 112 and the handle 113, in some embodiments of the present invention, the carrying body 112 has a first limiting part 1121, and the first limiting part 1121 is configured to abut against the handle 113 when the handle 113 rotates to the lifted position, so as to limit its further rotation. Referring to Figure 10 , the first limiting part 1121 can be a limiting post on the carrying body 112, and the limiting post abuts against the handle 113 (such as the connecting arm 1133 of the handle 113). Referring to Figure 12 , a receiving groove 1123 is provided on the carrying body 112, and the first limiting part 1121 is the groove wall on one side of the receiving groove 1123.

[0140] When the carrying component 110 includes the carrying body 112 and the handle 113, in some embodiments of the present invention, the carrying body 112 has a second limiting part 1122, and the second limiting part 1122 is configured to abut against the handle 113 when the handle 113 rotates to the initial placement, so as to limit its further rotation. Referring to Figure 11, the second limiting portion 1122 can be a limiting post on the bearing body 112, and the limiting post abuts against the handle 113 (such as the connecting arm 1133 of the handle 113). Refer to Figure 12 , a receiving groove 1123 is provided on the bearing body 112, and the second limiting portion 1122 is the groove wall on the other side of the receiving groove 1123.

[0141] The foregoing describes an example in which the bearing member 110 moves linearly. Next, another example of the bearing member 110 will be described, that is, a chain-type solution. Specifically, refer to Figures 13 to 15 , the bearing member 110 includes a plurality of bearing seats 111, and each bearing seat 111 is provided with at least one accommodating structure. The plurality of bearing seats 111 are sequentially connected to form a chain structure, and adjacent bearing seats 111 can rotate around the first axis of their connecting part. For example, when adjacent bearing seats 111 are rotatably connected by a rotating shaft 114, the first axis is the axis of the rotating shaft.

[0142] The chain structure includes a straight segment and an arc segment, and the arc segment is connected to one end of the straight segment. For example, refer to Figure 15 , the chain structure includes two straight segments and two arc segments. The two straight segments are arranged in parallel, and the two ends of the straight segment are respectively connected to the two arc segments, so as to form a closed chain structure. It should be noted that the chain structure is not limited to this form. For example, the two straight segments may not be parallel, or for another example, the chain structure includes more than two straight segments and more than two arc segments, so that the chain structure includes a part extending in an S shape.

[0143] Wherein, when the bearing member 110 moves relative to the housing assembly 400, the bearing seats 111 in the straight segment can move linearly. When adjacent bearing seats 111 are in the arc segment, adjacent bearing seats 111 can rotate around the first axis of their connection, and each adjacent bearing seat can rotate around the second axis of the arc segment. In this way, a cyclic motion of the chain structure can be achieved.

[0144] As a specific embodiment of the chain structure, the bearing member 110 further includes a plurality of rotating shafts 114, and adjacent bearing seats 111 are rotatably connected by the rotating shafts 114. For example, refer to Figure 17 , one end of the bearing seat 111 is provided with a rotating shaft 114, and the other end is provided with a rotating shaft hole 1113. Taking three adjacent bearing seats 111 as an example for explanation, the rotating shaft of the second bearing seat 111 passes through the rotating shaft hole 1113 of the first bearing seat 111, and the rotating shaft of the third bearing seat 111 passes through the rotating shaft hole 1113 of the second bearing seat 111. Connected in sequence, a plurality of bearing seats 111 can form a chain structure. It should be noted that in some embodiments, the rotating shaft 114 is connected to the bearing seat 111 as an independent part, and in other embodiments, the rotating shaft 114 and the bearing seat 111 are connected as an integral structure.

[0145] Referring to Figure 17 , more specifically, the carrier base 111 is further provided with a connecting plate 1116, and the connecting plate 1116 can also be connected to structures such as the aforementioned substrate 1111, for example, connected into an integral structure. The connecting plate 1116 includes a first section and a second section with a height difference, wherein a rotating shaft 114 is provided on the first section, and a rotating shaft hole 1113 is provided on the second section.

[0146] In this embodiment, the sample loading assembly 100 further includes a driving component 150. The driving component 150 includes a rotating disk 151 and a third power component 152. The third power component 152 can drive the rotating disk 151 to rotate around the aforementioned second axis, that is, the axis of the rotating disk 151 coincides with the second axis of the arc segment. The third power component 152 can drive the rotating disk 151 to rotate through a transmission mechanism such as a synchronous belt or a synchronous gear. Referring to Figure 16 , a plurality of first concave positions 1511 are provided along the circumferential direction of the rotating disk 151. The shape and size of the first concave positions 1511 are adapted to the embedding of the rotating shaft 114. For example, the first concave positions 1511 are arc-shaped concave positions.

[0147] In this embodiment, when adjacent carrier bases 111 are in the arc segment, the rotating shafts 114 between adjacent carrier bases 111 are correspondingly embedded in the first concave positions 1511 of the rotating disk 151. For the convenience of description, the process of embedding the rotating shaft 114 into the first concave position 1511 is called the meshing of the carrier base 111 and the rotating disk 151. As the rotating disk 151 rotates, the rotating disk 151 drives the carrier bases 111 in the arc segment to rotate around the second axis, and then the carrier bases 111 are separated from the rotating disk 151 and enter the straight segment, while the carrier bases 111 in the other straight segment continuously enter the arc segment to mesh with the rotating disk 151, so that the chain structure moves with the rotation of the rotating disk 151.

[0148] As another specific embodiment of the chain structure, the carrier component 110 further includes a plurality of rotating shafts 114. The adjacent carrier bases 111 are rotatably connected through the rotating shafts 114. For example, referring to Figures 18 to 20 , the carrier bases 111 are divided into two types, respectively named the first carrier base 115 and the second carrier base 116. Among them, rotating shafts 114 are provided at both ends of the first carrier base 115, and rotating shaft holes are provided at both ends of the second carrier base 116. Taking Figure 20 three adjacent carrier bases 111 shown as an example for description, the middle carrier base 111 is the first carrier base 115, and the carrier bases 111 on the left and right are the second carrier bases 116. The rotating shaft 114 at the left end of the first carrier base 115 passes through the rotating shaft hole of the second carrier base 116 on the left, and the rotating shaft 114 at the right end of the first carrier base 115 passes through the rotating shaft hole of the second carrier base 116 on the right. Connecting them in sequence, a plurality of carrier bases 111 can form a chain structure.

[0149] In this embodiment, referring to Figure 19 , the sample loading assembly 100 further includes a driving component 150. The driving component 150 includes a rotating disk 151 and a third power member 152. The third power member 152 can drive the rotating disk 151 to rotate around the aforementioned second axis, that is, the axis of the rotating disk 151 coincides with the second axis of the arc segment. The third power member 152 can drive the rotating disk 151 to rotate through a transmission mechanism such as a synchronous belt or synchronous gears.

[0150] Referring to Figure 19 , Figure 20 , the differences between this embodiment and the foregoing embodiments include: in the foregoing embodiments, the rotating disk 151 is provided with a first concave position 1511, and the rotating shaft 114 is embedded in the first concave position 1511. In this embodiment, the bearing seat 111 (including the first bearing seat 115 and the second bearing seat 116) is provided with a second concave position 1114. Moreover, a plurality of transmission teeth 1512 are arranged along the circumferential direction of the rotating disk 151. The shape of the transmission teeth 1512 is adapted to be embedded in the second concave position 1114. For example, the transmission teeth 1512 are approximately conical. The second concave position 1114 is adapted to be embedded by the transmission teeth 1512. In this embodiment, the second concave position 1114 penetrates through the bearing seat 111. Taking the first bearing seat 115 as an example, the first bearing seat 115 includes an upper chain plate 1117 and a lower chain plate 1118. The upper chain plate 1117 and the lower chain plate 1118 are spaced apart and connected by a rotating shaft 114. A second concave position 1114 is formed between the upper chain plate 1117 and the lower chain plate 1118.

[0151] More specifically, the bearing seat 111 of this embodiment includes a connecting portion for forming a chain structure and a bearing portion for bearing the sample container 10. In some embodiments, the first bearing seat 115 includes the aforementioned connecting portion and bearing portion, and the second bearing seat 116 includes a connecting portion. Taking Figure 20 the first bearing seat 115 in

[0152] In this embodiment, when the carrier seat 111 is in the arc section, the transmission gear 1512 is correspondingly embedded in the second concave position 1114 of the carrier seat 111. For the convenience of description, the process of embedding the transmission gear 1512 into the second concave position 1114 is called the meshing of the carrier seat 111 and the rotating disk 151. As the rotating disk 151 rotates, the rotating disk 151 drives the carrier seat 111 to rotate around the second axis, and then the carrier seat 111 separates from the rotating disk 151 and enters the straight section. The carrier seat 111 in the other straight section continuously enters the arc section to mesh with the rotating disk 151, thereby realizing cyclic drive.

[0153] When multiple carrier seats 111 form a chain structure, in some embodiments of the present invention, both the first axis and the second axis are arranged horizontally. At this time, there is a height difference between the two straight sections of the chain structure, that is, one straight section is located above the other straight section, and the straight section located above is used to carry and transport the sample container 10. Correspondingly, the transfer assembly 200 needs to remove the sample container 10 from the carrying member 110 before the sample container 10 reaches the arc section. More specifically, the two straight sections of the chain structure are arranged in parallel, so that the heights of the two second axes are equal.

[0154] When multiple carrier seats 111 form a chain structure, in some embodiments of the present invention, both the first axis and the second axis are arranged vertically. For example Figure 15 、 Figure 18 as shown, at this time, the heights of the straight sections and the arc sections of the chain structure are all equal, and all can be used to carry and transport the sample container 10.

[0155] When multiple carrier seats 111 form a chain structure, in some embodiments of the present invention, a part of the chain structure is located outside the housing assembly 400, and another part is located inside the housing assembly 400. As the carrying member 110 moves, the part of the chain structure located outside the housing assembly 400 can enter the housing assembly 400, and the part located inside the housing assembly 400 can be sent out of the housing assembly 400. The controller is further configured to control the transfer assembly 200 to transfer the sample container 10 from the part of the chain structure located inside the housing assembly 400.

[0156] For example, when both the first axis center and the second axis center are arranged in the vertical direction, one straight line segment and two arc segments of the chain structure are both located inside the housing assembly 400, and the other straight line segment is located outside the housing assembly 400 for the user to place the sample container 10; when both the first axis center and the second axis center are arranged in the horizontal direction, along the height direction of the chain structure, the lower straight line segment and the two arc segments are both located inside the housing assembly 400, and the upper straight line segment is located outside the housing assembly. Along the length direction of the chain structure, a part of the upper straight line segment is located outside the housing assembly 400 for the user to place the sample container 10, and another part of the upper straight line segment is located inside the housing assembly 400.

[0157] When a plurality of carrier seats 111 form a chain structure, in some embodiments of the present invention, the carrier member 110 is configured to be intermittently movable relative to the housing assembly 400. And when the carrier member 110 is stationary relative to the housing assembly 400, the controller is further configured to control the transfer assembly 200 to transfer the sample container 10 from the accommodating structure on the chain structure located inside the housing assembly 400. In this way, the transfer assembly 200 can stably transfer the sample container 10 from the accommodating structure on the chain structure. It should be noted that, in some embodiments, the transfer assembly 200 can transfer the sample container 10 at a fixed transfer position. In order to enable the carrier seat 111 to accurately stay at the transfer position, the loading assembly 100 can also be provided with a positioning sensor for positioning the carrier seat 111. For example, the loading assembly 100 is provided with a transmissive opto-coupler at the transfer position, and a baffle is provided on the carrier seat 111. When the baffle triggers the transmissive opto-coupler, the chain structure stops moving, and thus the carrier seat 111 can be stopped at the transfer position.

[0158] Based on the first embodiment, in some embodiments of the present invention, referring to Figure 18 , the microbial detector further includes an identification component 800. The identification component 800 is used to identify whether there is a sample container 10 in the accommodating structure. The controller is further configured to: when the identification component 800 identifies that there is a sample container 10 in the accommodating structure, control the transfer assembly 200 to transfer the sample container 10 in the accommodating structure. In this way, it can be avoided that the transfer assembly 200 grabs nothing, and the working efficiency can be improved.

[0159] It should be noted that when the recognition component 800 recognizes the sample container 10 in the accommodation structure, the carrying component 110 can temporarily stop moving, and the transfer component 200 can transfer the sample container 10 from the accommodation structure in a timely manner. It is also possible that the recognition component 800 first recognizes all the accommodation structures. After the carrying component 110 moves to a set position, the transfer component then transfers the sample containers 10 in each accommodation structure in sequence according to the recognition results. For example, the sample loading component includes a recognition position, which can be understood as a fixed spatial area within the housing component 400, but the shape and size of this area are not limited. The carrying component 110 includes a plurality of carrying seats 111. When the plurality of carrying seats 111 form a chain structure, the accommodation structures in each carrying seat 111 can pass through the recognition position in sequence as the carrying component 110 moves, and thus are sequentially recognized by the recognition component 800. When the recognition component 800 recognizes that the accommodation structure of a certain carrying seat 111 has a sample container 10, the chain structure stops moving. After the transfer component 200 transfers the sample container 10 in this accommodation structure, the chain structure moves again. Another example is that when the carrying component 110 can move linearly in the first direction, the recognition component 800 is arranged on the moving path of the carrying component 110, such as at the first channel opening 410. In this way, during the process of the recognition component 800 moving from the extended position to the retracted position, each accommodation structure will pass through the recognition component 800. After the recognition component 800 moves to the retracted position, the controller controls the transfer component 200 to transfer the sample containers 10 in the carrying component 110 based on whether there are sample containers in all the accommodation structures recognized by the recognition component 800.

[0160] The recognition component 800 can have different solutions. In some specific embodiments, the recognition component 800 can be a camera device with a photographing function, and the controller determines whether there is a sample container 10 in the accommodation structure based on the image captured by the camera device; in other embodiments, the recognition component 800 includes a transmissive sensor or a reflective sensor, and the controller determines whether there is a sample container 10 in the accommodation structure based on whether the sensor receives a light signal.

[0161] It should be noted that the microbial detector may not be provided with the recognition component 800, and the transfer component 200 performs transfer operations on each accommodation structure one by one. For example, when the carrying component 110 includes the aforementioned chain structure, the chain structure will pause when each carrying seat 111 moves to the transfer position. The transfer component 200 performs a transfer operation on the accommodation structure in the carrying seat 111 at the transfer position, and determines whether the sample container 10 is grabbed by detecting factors such as the force received by the transfer component during the transfer operation. Another example is that when the carrying component 110 can move linearly between the extended position and the retracted position, after the carrying component 110 moves to the retracted position, the transfer component 200 performs transfer operations on each accommodation structure in sequence.

[0162] Based on the first embodiment, in some embodiments of the present invention, the carrier member 110 further includes a turntable, which can rotate relative to the housing assembly 400 around its own axis. A plurality of placement accommodating structures are arranged on the turntable along its rotation direction. Among them, a part of the turntable is located inside the housing assembly 400, and the other part is located outside the housing assembly 400. In this way, the user can place the sample container 10 in the accommodating structure of the part of the turntable located outside the housing assembly 400. As the turntable rotates, the sample container 10 can be transported into the housing 400 assembly and then transferred by the transfer assembly 200. The control of the turntable can be understood with reference to the chain structure. For example, the turntable rotates intermittently, and the transfer assembly 200 transfers the sample container 10 when the turntable stops. Another example is that when the identification assembly 800 identifies that there is a sample container 10 in a certain accommodating structure on the turntable, the turntable stops moving, and the transfer assembly 200 performs a transfer operation on the sample container 10 in this accommodating structure.

[0163] Based on the first embodiment, in some embodiments of the present invention, with reference to Figure 3 , Figure 13 and Figure 14 , the microorganism detector further includes an information acquisition component 500. The information acquisition component 500 is used to perform information acquisition operations on the sample container or the sample in the sample container. The controller is further configured to control the transfer assembly 200 to transfer the sample container 10 that has completed the information acquisition operation to the incubation component 300. Among them, the information of the sample container 10 can be acquired by the information acquisition component 500 in the accommodating structure, or the sample container 10 can be separated from the accommodating structure first and then the information is acquired by the information acquisition component 500. This will be described in combination with different embodiments later.

[0164] When the microorganism detector further includes an information acquisition component 500, in some embodiments, the information acquisition component 500 further includes an information acquisition part and a rotating part. The rotating part is used to place the sample container 10 and can drive the carried sample container 10 to rotate synchronously, and the rotation angle is usually greater than or equal to 360°. In this embodiment, the rotating part and the carrier member 110 are located in different areas. Therefore, the transfer assembly 200 needs to first transfer the sample container 10 on the carrier member 110 to the rotating part. After the information acquisition component 500 performs the information acquisition operation, the transfer assembly 200 then transfers the sample container 10 from the rotating part to the incubation component 300.

[0165] In this embodiment, the controller is configured to control the information acquisition component of the information acquisition component 500 to perform information acquisition operations during the rotation of the sample container 10. In this way, the information acquisition component can more comprehensively acquire the information of the sample container 10 or the sample in the sample container 10, reducing omissions. On the other hand, in this embodiment, the rotation component drives the sample container 10 to rotate synchronously, and there is no relative movement between the sample container 10 and the rotation component. Therefore, it is possible to prevent the bottom of the sample container 10 from being worn and affecting transparency, thereby affecting the detection results of the detection component.

[0166] When the information acquisition component 500 further includes a rotation component, in some embodiments of the present invention, the rotation component may be a turntable. The axis of the turntable is arranged in the vertical direction, and the turntable is driven to rotate by a power component such as a motor. The information acquisition component performs information acquisition operations from the side. This method is applicable to sample containers placed vertically. In some specific embodiments, the sample container 10 can be directly placed on the turntable. In other embodiments, a placement structure similar to a containment structure may also be provided on the turntable to achieve stable placement of the sample container 10.

[0167] When the information acquisition component 500 further includes a rotation component, in some embodiments of the present invention, the rotation component may be relatively arranged rotating rollers. The axes of the rotating rollers are parallel to the horizontal direction and are driven by a power component such as a motor. The information acquisition component performs information acquisition operations from above. This method is applicable to sample containers placed horizontally.

[0168] When the information acquisition component 500 further includes a rotation component, in some embodiments of the present invention, along the first direction, the information acquisition position is located between the sample loading component 100 and the incubation component 300. In this way, it is convenient for the transfer component 200 to transfer the sample container 10 from the loading component 110 to the information acquisition position and from the information acquisition position to the incubation component 300 with a shorter stroke, which helps to reduce the volume of the microbial detector. For example, when the loading component 110 can move relative to the housing component 400 to switch between the extended position and the retracted position, the first direction is the moving direction of the loading component 110.

[0169] It should be noted that when the sample container 10 obtains information by the information acquisition component 500 on the rotation component instead of on the loading component 110, there is no need to consider whether the occlusion of the containment structure on the sample container 10 will affect information acquisition. Therefore, the loading component 110 can be as Figure 18 、 Figure 20As shown, the annular side plate of the accommodating structure of the bearing seat 111 is circumferentially closed without any notch, so it has better positioning ability. When the sample container 10 is on the bearing member 110 and information is acquired by the information acquisition component, if the accommodating structure blocks the sample container 10, it will affect the information acquisition by the information acquisition component 500. Based on this, the bearing member 110 can be as Figure 15 , Figure 17 shown, the annular side plate of the accommodating structure of the bearing seat 111 has a notch, and the part of the sample container 10 inserted into the accommodating structure can be exposed from the notch.

[0170] When the microorganism detector further includes an information acquisition component 500, in some embodiments, the controller is further configured to control the transfer component 200 to drive the sample container 10 placed on the accommodating structure to rotate, and control the information acquisition component 500 to perform information acquisition operations during the rotation of the sample container 10. That is, this embodiment is applicable to the scenario where the information acquisition component 500 acquires information from the sample container 10 within the accommodating structure. This embodiment utilizes the existing transfer component 200 to drive the sample container 10 to rotate, without the need to set up an additional rotating part, which can reduce the number of components.

[0171] It should be noted that since the sample container 10 stays within the accommodating structure during information acquisition, the accommodating structure can be as Figure 17 shown to be provided with an information acquisition window that can expose the sample container 10.

[0172] It should also be noted that in this embodiment, after the information acquisition component 500 completes the information acquisition operation, the transfer component 200 can directly transfer the sample container 10 to the incubation component 300.

[0173] When using the transfer component 200 to rotate the sample container, in some embodiments of the present invention, the transfer component 200 includes a clamping jaw and a rotation power component. The clamping jaw is used to clamp the sample container 10, and the rotation power component can be a rotating motor, which can drive the clamping jaw to rotate.

[0174] When the microorganism detector further includes an information acquisition component 500, in some embodiments, referring to Figure 15 , the sample loading component 100 further includes a rotating part 160. The controller is further configured to control the rotating part 160 to drive the sample container 10 placed on the accommodating structure to rotate, and control the information acquisition component 500 to perform information acquisition operations during the rotation of the sample container 10. That is, this embodiment is applicable to the scenario where the information acquisition component 500 acquires information from the sample container 10 within the accommodating structure.

[0175] Specifically, when the carrier member 110 includes the aforementioned chain structure, the microorganism detector sequentially has an information acquisition position and a transfer position along the movement direction of the chain structure. Taking one of the carrier seats 111 as an example, after the carrier seat 111 reaches the information acquisition position, the sample container 10 thereon is driven to rotate by the rotating member 160. During the rotation process, the information acquisition operation is performed by the information acquisition component 500. Then the chain structure moves. When the carrier seat 111 reaches the transfer position, the transfer component 200 transfers the sample container 10 on the carrier seat 111 to the incubation component 300.

[0176] When rotating the sample container by the rotating member 160, in some embodiments of the present invention, the rotating member 160 is disposed above the sample container 10, and the information acquisition component 500 acquires information from the side of the sample container 10.

[0177] On the basis of the first embodiment, in some embodiments of the present invention, the microorganism detector further includes an information acquisition component 500, and the information acquisition component 500 is used to perform an information acquisition operation on the sample container or the sample in the sample container. In this embodiment, the controller is further configured to control the transfer component 200 to drive the sample container 10 in the accommodation structure to lift upward, drive the sample container 10 to rotate after lifting, control the information acquisition component 500 to perform an information acquisition operation during the rotation of the sample container 10, and control the transfer component 200 to transfer the sample container 10 that has completed the information acquisition operation to the incubation component 300.

[0178] In this embodiment, the transfer component 200 can lift the sample container 10 to separate it from the accommodation structure. Therefore, the sample container 10 will not be blocked by the accommodation structure. The accommodation structure can adopt, for example Figure 20 the accommodation structure with a complete annular side wall as shown. On the other hand, the sample container 10 will not rub against the accommodation structure during the rotation process. Therefore, it can be avoided that the bottom of the sample container 10 is scratched and the transparency is affected. At the same time, in this embodiment, the existing transfer component 200 is used to drive the sample container 10 to rotate, and no additional rotating member needs to be provided, which can reduce the number of components. In addition, in this embodiment, when the information acquisition component 500 completes the information acquisition operation, the transfer component 200 can directly transfer the sample container 10 to the incubation component 300.

[0179] Based on the first embodiment, in some embodiments of the present invention, the microbial detector further includes an information acquisition component 500. The information acquisition component 500 is configured to perform an information acquisition operation on the sample container or the sample in the sample container. The sample component 100 further includes a rotating member 160. In this embodiment, the controller is further configured to control the rotating member 160 to drive the sample container 10 in the accommodating structure to be lifted upward, and after the lifting, drive the sample container 10 to rotate, control the information acquisition component 500 to perform an information acquisition operation during the rotation of the sample container 10, control the rotating member 160 to place the sample container 10 that has completed the information acquisition operation downward back into the accommodating structure, and control the transfer component 200 to transfer the sample container 10 that has completed the information acquisition operation from the accommodating structure to the incubation component 300.

[0180] For example, when the carrying member 110 includes the aforementioned chain structure, the microbial detector sequentially has an information acquisition position and a transfer position along the movement direction of the chain structure. Taking one of the carrying seats 111 as an example, after the carrying seat 111 reaches the information acquisition position, the rotating member 160 drives the sample container 10 thereon to be lifted upward and rotate. During the rotation, the information acquisition component 500 performs an information acquisition operation. After the information acquisition component 500 completes the information acquisition operation, the rotating member 160 drives the sample container 10 to descend to place it back into the accommodating structure. Then the chain structure moves. When the carrying seat 111 reaches the transfer position, the transfer component 200 transfers the sample container 10 on the carrying seat 111 to the incubation component 300.

[0181] In this embodiment, the rotating member 160 can lift the sample container 10 to separate it from the accommodating structure. Therefore, the sample container 10 will not be blocked by the accommodating structure. The accommodating structure can adopt, for example Figure 20 the accommodating structure shown with a complete annular side wall. On the other hand, the sample container 10 will not rub against the accommodating structure during rotation. Therefore, it is possible to avoid the bottom of the sample container 10 from being scratched and affecting transparency. At the same time, in this embodiment, the rotating member 160 is used to drive the sample container 10 to rotate, and the transfer component 200 can perform other transfer operations during this period.

[0182] When the microbial detector further includes an information acquisition component 500, in some embodiments, the controller is further configured to: when the information acquisition component 500 completes the information acquisition operation on one sample container 10, during the process of controlling the transfer component 200 to transfer the sample container 10 to the incubation component 300, control the information acquisition component 500 to synchronously perform the information acquisition operation on another sample container 10. That is, the information acquisition component 500 can utilize the time when the transfer component 200 transfers the sample container 10 to the incubation component 300 to acquire the information of other sample containers 10. In this way, the waiting time of the transfer component 200 can be reduced, which helps to improve the efficiency.

[0183] Specifically, in some embodiments, the sample container 10 undergoes an information acquisition operation by the information acquisition component 500 on the carrier component 110. For example, referring to Figure 15 (The information acquisition component is not shown in the figure), the carrier component 110 includes the aforementioned chain structure. The microorganism detector sequentially has an information acquisition position and a transfer position along the movement direction of the chain structure. Taking one of the carrier seats 111 as an example, the carrier seat 111 first undergoes an information acquisition operation by the information acquisition component 500 at the information acquisition position. After the information acquisition operation is completed, the chain structure continues to move. When the carrier seat 111 reaches the transfer position, another carrier seat 111 also reaches the information acquisition position. The transfer component 200 transfers the sample container 10 on the carrier seat 111 to the incubation component 300. During the process of the transfer component 200 transferring the sample container 10 on the carrier seat 111 to the incubation component 300, the information acquisition component 500 simultaneously performs an information acquisition operation on the sample containers 10 on some other carrier seats 111.

[0184] In some other embodiments, the microorganism detector has an information acquisition position disposed at a different location from the carrier component 110. The transfer component 200 needs to first transfer the sample container 10 to the information acquisition position for the information acquisition component 500 to obtain information, and then transfer the sample container 10 from the information acquisition position to the incubation component 300. For example, the information acquisition component 500 includes the aforementioned rotating component, and the rotating component is disposed at the information acquisition position. Among them, multiple information acquisition positions are set. For example, multiple rotating components are provided. When at least one of the multiple information acquisition positions is in an empty state and at least another information acquisition position contains a sample container 10, the information acquisition position in the empty state is defined as the first acquisition position, and the information acquisition position containing the sample container 10 is defined as the second acquisition position.

[0185] Among them, the controller is further configured to control the transfer component 200 to first transfer the sample container 10 on the accommodation structure to the first acquisition position, and then transfer the sample container 10 with acquired information in the second acquisition position to the incubation component 300. During the process of transferring the sample container 10 in the second acquisition position to the incubation component 300, the information acquisition component 500 simultaneously performs an information acquisition operation on the sample container 10 in the first acquisition position.

[0186] It should be noted that when the information acquisition component 500 includes multiple information acquisition positions, the information acquisition operation can be performed on the sample containers 10 or the samples therein in the multiple information acquisition positions by a single information acquisition component respectively, or multiple information acquisition components can be provided to perform the information acquisition operation on the sample containers 10 or the samples therein in the multiple information acquisition positions respectively.

[0187] When the microorganism detector further includes an information acquisition position and an information acquisition component 500, in some embodiments of the present invention, the controller is configured to obtain the identification code information of the sample container 10 according to the information acquired by the information acquisition component 500. In some specific embodiments, the information acquisition component 500 includes a scanning component with a scanning function, and the scanning component obtains the identification code information by scanning the identification code on the sample container 10; in other specific embodiments, the information acquisition component 500 includes an acquisition component with an image acquisition function (such as a camera), and the controller obtains the identification code information based on the image acquired by the acquisition component.

[0188] It should be noted that the identification code on the sample container 10 includes a first identification code for associating sample information and a second identification code for associating sample container information. The sample information associated with the first identification code includes sample type information. For example, the sample is a blood, sputum or other type of biological fluid sample. The sample information associated with the first identification code can also be associated with the patient information of the sample and / or the sampling time of the sample. The sample container information associated with the second identification code includes the type information of the sample container 10. For example, the sample container 10 is an aerobic bottle or an anaerobic bottle. In this embodiment, the identification code on the sample container 10 includes two identification codes, namely the first identification code and the second identification code. Of course, in specific applications, the setting method of the identification code on the sample container 10 is not limited to this, and it can also be one or more than three. For example, as an alternative implementation, the identification code on the sample container 10 can also only have the first identification code; or, as another alternative implementation, in addition to the above-mentioned first identification code and second identification code, the identification code on the sample container 10 can also include a third identification code for associating sample source information and / or a fourth identification code for associating patient information.

[0189] It should also be noted that the identification code on the sample container 10 includes at least one of a bar code, a two-dimensional code, and a radio frequency code.

[0190] When the microbial detector further includes an information acquisition component 500, in some embodiments of the present invention, the controller is configured to obtain the sample volume information of the sample in the sample container 10 according to the information acquired by the information acquisition component 500. In some specific embodiments, the information acquisition component 500 is configured to obtain the liquid level information of the sample container 10 placed at the information acquisition position, and the controller obtains the sample volume information of the sample in the sample container 10 through the liquid level information. Among them, the information acquisition component 500 includes an acquisition component with an image acquisition function (such as a camera); in other embodiments, the information acquisition component 500 is configured to obtain the total weight information of the sample container 10 and the sample placed at the information acquisition position, and the controller obtains the sample volume information of the sample in the sample container 10 through the weight information of the sample container 10. For example, the weight information of the sample container 10 is preset in the controller, and the weight information of the sample can be obtained by the difference between the total weight information and the weight information of the sample container. Then, the sample volume information is obtained based on the weight information and the database or curve preset in the controller. Another example is that the controller directly obtains the sample volume information through the total weight information and the database or curve preset in the controller. Among them, the information acquisition component 500 includes a weighing component with a weighing function.

[0191] When the microbial detector further includes an information acquisition component 500, in some embodiments of the present invention, the controller is configured to obtain the type information of the sample in the sample container 10 according to the information acquired by the information acquisition component 500. For example, the controller determines whether the sample in the sample container 10 is a blood sample according to the information acquired by the information acquisition component 500. The microbial detector can be used for culturing and detecting blood samples, and can also be used for culturing and detecting other body fluids. In this embodiment, before culturing and detecting the sample in the sample container 10, the controller first determines whether the sample in the sample container 10 is a blood sample, which is beneficial for the controller to better distinguish and detect each sample to ensure the accuracy of the detection results of each sample.

[0192] When the sample in the sample container 10 is a blood sample, the microbial detector can detect bloodstream infection of the blood sample through blood culture method. The operation method in its specific application is as follows: Add the blood sample drawn from the patient into the sample container 10 (such as a blood culture bottle). After the microbial detector obtains the identification code information and the sample volume information, place the sample container 10 loaded with the blood sample in the microbial detector for culturing to make the bacteria multiply, and detect the growth of the bacteria through the detection component, so as to know whether the patient has bloodstream infection. Since the number of bacteria in the patient's blood is not large, the amount of the blood sample added to the sample container 10 determines the number of bacteria added to the sample container 10. If the amount of the blood sample added to the sample container 10 is too small, the number of bacteria added to the sample container 10 is small or there are no bacteria at all, which will affect the reproduction and growth of the bacteria and may lead to false test results. While if the amount of the blood sample added to the sample container 10 is too large, the respiration of a large number of blood cells in the blood sample also produces carbon dioxide, and it is impossible to determine whether the carbon dioxide in the culture bottle is produced by the microorganisms or the blood cells in the blood sample, resulting in the possibility of false positives in the test results. Therefore, before performing blood culture detection on the blood sample, it is necessary to obtain the information of the amount of the blood sample in the sample container 10 (in this implementation, it is obtained by obtaining the liquid level in the sample container 10), so as to facilitate the controller to comprehensively analyze the test results by combining the information of the amount of the blood sample in the sample container 10 and the detection information of the detection component.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
