Description

Technical Field

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

[0002] A microbial detector is a device used for culturing microorganisms and detecting 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, the sample loading component of the microbial detector usually uses a conveyor belt as the sample loading mechanism. In order to facilitate receiving the sample container, at least a part of the conveyor belt needs to be kept outside the device housing. On the one hand, there is a risk of being damaged, and on the other hand, it is also easily contaminated by external pollution sources. In addition, in related technologies, users usually place the sample containers on the sample loading mechanism disorderly. 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.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0068] The present invention provides a microorganism detector that 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 microorganism 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 microorganism 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 ease of understanding, first, the components of the microorganism detector and its main working modes will be described.

[0069] 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, and 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).

[0070] The transfer assembly 200 is used to transfer the sample container 10, for example, to transfer the sample container 10 from the loading assembly 100 to the incubation assembly 300, or to transfer 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 a three-dimensional space. The manipulator is used to grip 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 the illustrated embodiment, the transfer assembly 200 includes the aforementioned manipulator, moving power mechanism, and rotational power mechanism.

[0071] 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 that can drive the sample container 10 to move, so that the sample in the sample container 10 is fully mixed with the growth medium. In some specific embodiments, the incubation assembly 300 includes an incubation frame, 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 frame through a horizontally arranged rotating shaft, and the incubation driving mechanism can drive the incubation seat to swing reciprocally around the rotating shaft, thereby realizing the batch mixing of a plurality of sample containers 10.

[0072] The detection assembly is used to detect the growth of microorganisms in the sample container 10 placed in the incubation assembly 300, so that the controller can judge whether the growth of microorganisms meets the standard based on the detection results of the detection assembly. In some embodiments, the detection assembly performs detection based on a colorimetric method. For example, a color-developing element is provided inside the sample container 10 (specifically, its bottom), and the color-developing element changes color according to the growth of microorganisms in the sample container 10. The detection assembly can detect the growth of microorganisms by detecting the color change of the color-developing element. In other embodiments, the detection assembly can also detect based on the fluorescence of microorganisms.

[0073] 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 (i.e., the sample containers 10 with qualified microorganism growth). 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 (i.e., the sample containers 10 with no or unqualified microorganism growth). The negative containers in the negative container storage component 700 will be taken away and discarded by the user. For Figures 1 to 3 example, the housing component 400 is respectively provided with a second channel opening 420 and a third channel opening 430 corresponding to the positive container storage component 600 and the negative container storage component 700. Both the second channel opening 420 and the third channel opening 430 are closed by covers. Opening the corresponding covers can take away the positive container or the negative container.

[0074] Combined with the above structure, a typical microorganism detection process is described as follows: The user sends the sample container 10 into the sample loading component 100, and the transfer component 200 transfers the sample 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.

[0075] In the related art, the sample loading component of the microorganism detector usually uses a conveyor belt as the sample loading mechanism. In order to facilitate receiving the sample container 10, at least a part of the conveyor belt needs to be kept outside the device housing. On the one hand, there is a risk of being damaged, and on the other hand, it is also easily contaminated by external pollution sources. Based on this, referring to Figure 1 、 Figure 2 , the sample loading component 100 in this embodiment includes a carrying component 110. The carrying component 110 can move relative to the housing component 400 to switch between the extended position and the retracted position. When it is in the extended position, at least part of the carrying component 110 extends outside the housing component 400 for the user to put the sample container 10. When it is in the retracted position, the carrying component 110 is located inside the housing component 400. In this way, the hiding of the carrying component 110 can be realized, and the risks of the carrying component 110 being damaged and contaminated can be reduced.

[0076] 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.

[0077] On the basis of the first embodiment, in some embodiments of the present invention, the carrying component 110 has a plurality of spaced accommodation structures, and the accommodation structures are used to accommodate the sample containers 10. In this way, the user has sorted the sample containers 10 when placing the sample containers 10 in the accommodation structures in the carrying component 110, so there is no need to set up 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 accommodation structure can accommodate the sample containers 10 to position them, thereby reducing the mutual collision of the sample containers 10, thereby reducing the tipping of the sample containers 10, and ensuring the normal progress of the sample loading process. Among them, the carrying component 110 has a plurality of placement positions 111, and the accommodation structures are arranged in the corresponding placement positions 111, wherein the placement position 111 can be understood as a certain area, but the area and shape of the area are not limited.

[0078] Specifically, 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.

[0079] It should be noted that when the carrying component 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 component 110 along the horizontal direction.

[0080] In some embodiments of the present invention, when the accommodating structure can at least restrict the relative movement between the sample container 10 and the carrying member 110 in the horizontal direction, 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 restrict 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, after 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, after 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 tilts to a certain extent in the accommodating structure and then comes into contact with the positioning portion for positioning.

[0081] 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 restrict 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 embodiments, 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 fits 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.

[0082] In some embodiments of the present invention, when the accommodating structure includes a carrying portion and a positioning portion, 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.

[0083] In some embodiments of the present invention, when the accommodating structure includes a carrying and positioning portion, 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 fits the outer contour of the sample container 10, or the inner wall surface of the foregoing annular clamp.

[0084] When the carrying part and the positioning part jointly form an accommodating space for accommodating the sample container 10, in some embodiments of the present invention, the carrying member 110 includes at least one carrying seat for setting the accommodating structure, and the accommodating space is concave relative to the carrying seat. For example, the carrying seat is Figure 4 the rectangular carrying seat shown, and the substrate is provided with an accommodating structure. In some embodiments, the accommodating structure is a placement hole formed by being concave downward from the upper side surface of the substrate. At this time, the carrying part includes the bottom wall surface of the placement hole, and the positioning part includes the side wall surface of the placement hole. When the sample container 10 is inserted into the placement hole, the bottom wall of the placement hole 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. Refer to Figure 4 , the carrying member 110 includes two carrying seats, and a plurality of spaced-apart placement holes are provided on each carrying seat. The plurality of placement holes can be arranged in an array, for example, in a rectangular array.

[0085] When the carrying part and the positioning part jointly form an accommodating space for accommodating the sample container 10, in some embodiments of the present invention, the carrying member 110 includes at least one carrying seat for setting the accommodating structure, and the accommodating space is convex relative to the substrate. Specifically, the carrying seat includes a substrate and a protruding part, and the protruding part protrudes relative to the substrate. At this time, the carrying part includes the surface on the substrate that defines the accommodating space with the protruding part, and the positioning part includes the surface on the protruding part that defines the accommodating space with the substrate. When the sample container 10 is placed on the substrate, the protruding part can cooperate with the side surface of the sample container 10 to limit the horizontal movement of the sample container 10 relative to the carrying seat. For example, the protruding part is an annular side plate extending from the upper side surface of the substrate, and among them, the annular side plate can be closed in the circumferential direction or provided with a notch. In other embodiments, a plurality of protruding parts for positioning a single sample container 10 are provided, and the plurality of protruding parts are spaced apart along the circumference of the sample container 10. More specifically, the protruding part can be provided as an elastic structure.

[0086] Based on the first embodiment, in some embodiments of the present invention, the aforementioned carrying member 110 can move relative to the housing assembly 400 to switch between the extended position and the retracted position. Specifically, it means that the carrying member 110 can move relative to the housing assembly 400 along a first direction to switch between the extended position and the retracted position. In other words, the carrying member 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 carrying member 110 to quickly reach the extended position or the retracted position. Taking Figure 1 、 Figure 2 shown as an example, the first direction is the front-back direction in the figure (the front side refers to the side of the housing assembly 400 with the human-computer interaction channel opening).

[0087] 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.

[0088] When the carrying component 110 is capable of moving along the first direction, in some embodiments of the present invention, the carrying component 110 has a plurality of placement positions 111 for placing the sample container 10, and the placement positions 111 can be understood with reference to the aforementioned embodiments. In some embodiments, the plurality of placement positions 111 can be arranged in an array, for example, in a rectangular array, wherein in some embodiments, the sample loading component 100 can be provided with a single larger carrying component 110; in other embodiments, the sample loading component 100 can be provided with a plurality of carrying components 110. Figure 4 As shown in the example, the sample loading component 100 includes two supporting components 110 arranged in parallel, and each supporting component 110 has a plurality of placement positions 111 arranged in a rectangular array.

[0089] 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 box, wherein the transfer area refers to: the transfer component 200 can obtain the sample container 10 in the support component 110 entering the housing component 400 within the area within the area, and the present embodiment does not limit the size and position of the transfer area. 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 support component 110 moves to the retracted position along the first direction, only some of the multiple placement positions 111 are located within the transfer area, and the transfer component 200 can only transfer the sample container 10 in the placement position 111 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 support component 110 has a large number of placement positions 111, the transfer component 200 can only obtain the sample container 10 in some of the placement positions 111. For example, in Figure 4 In the embodiment, when the carrying member 110 is in the retracted position, only the placement position 111 in the left area is located in the transfer area, and the placement position 111 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 placement position 111 of the middle area is located in the transfer area, and the placement position 111 of the left area and the placement position 111 of the right area are located outside the transfer area.

[0090] Based on the above, the carrier member 110 of the present embodiment is further configured to be movable at least between a retracted position and a first position along a second direction intersecting the first direction. The carrier member 110 has at least a first region and a second region arranged along the second direction. At least one placement position 111 is provided in both the first region and the second region. Among them, the first region and the second region are different but may have a common region. In other words, the first region and the second region do not completely overlap, or the first region and the second region have a partially overlapping region. Some placement positions 111 can be considered to be in the first region or in the second region. For example Figure 9 as shown

[0091] When the carrier member 110 is in the first position, the transfer assembly 200 can transfer the sample container 10 from the placement position 111 in the first region. When the carrier member 110 is in the retracted position, the transfer assembly 200 can transfer the sample container 10 from the placement position 111 in the second region. That is, by moving the carrier member 110 along the second direction, the placement positions 111 in different regions of the carrier member 110 can be respectively located in the transfer region, so that the transfer assembly 200 can access the placement positions 111 in all regions of the sampling assembly 100. For example, in Figure 8 the carrier member 110 includes a first region and a second region. In the figure, the first region to the second region is exemplarily divided by a vertical dotted line. The right side is the first region and the left side is the second region. The carrier member 110 can move between the first position and the retracted position. When the carrier member 110 is in the retracted position, the placement positions 111 in the second region are located in the transfer region, and the placement positions 111 in the first region are located outside the transfer region. After the transfer assembly 200 removes all the sample containers 10 in the second region, the carrier member 110 moves from the retracted position to the first position in the leftward direction, so that the placement positions 111 in the first region are located within the transfer region, and then the transfer assembly 200 removes all the sample containers 10 in the first region; Another example is in Figure 9In it, the carrier component 110 includes a first region, a second region, and a third region. The right side is the first region, the middle is the second region, and the left side is the third region. In the figure, the first region to the third region are exemplarily divided by vertical dotted lines. The carrier component 110 can move between a first position, a retracted position, and a second position. When the carrier component 110 is in the retracted position, the placement position 111 of the second region is within the transfer region, and the placement positions 111 of the first region and the third region are outside the transfer region. After the transfer assembly 200 removes all the sample containers 10 in the second region, the carrier component 110 first moves from the retracted position in the leftward direction to the first position, so that the placement position 111 of the first region on the right side is within the transfer region. After the transfer assembly 200 removes all the sample containers 10 in the first region, the carrier component 110 then moves from the first position in the rightward direction to the second position, so that the placement position 111 of the third region on the left side is within the transfer region. Then the transfer assembly 200 removes all the sample containers 10 in the third region.

[0092] It should be noted that, in some specific embodiments, the second direction is perpendicular to the first direction, and both are horizontal directions.

[0093] In some specific embodiments, referring to Figure 3 , two incubation assemblies 300 are provided. Along the second direction (such as Figure 3 the left - right direction in [[ ]]), the two incubation assemblies 300 are arranged in parallel at intervals. An inlet of the incubation tank is provided on the side where the two incubation assemblies 300 face each other. The transfer assembly 200 is located between the two incubation assemblies 300, so as to facilitate selectively feeding the sample containers 10 into the incubation assemblies 300 on both sides.

[0094] It should be noted that since the transfer assembly 200 is located between the two incubation assemblies 300, the maximum stroke of the transfer assembly 200 along the second direction will be limited by the incubation assemblies 300 on both sides. In order to be able to carry more sample containers 10 at one time, the loading assembly 100 in this embodiment has more placement positions 111. Specifically, the maximum distance between the placement positions 111 of the loading assembly 100 along the second direction is longer than the maximum stroke of the transfer assembly 200 along the second direction, that is, the length of the transfer region along the second direction. At this time, the carrier component 110 can move along the second direction to enable the transfer assembly 200 to obtain the sample containers 10 in the placement positions 111 of each region on the loading assembly 100.

[0095] Based on the first embodiment, in some embodiments of the present invention, a plurality of carrier members 110 are provided. For example, the number of carrier members 110 is set to two, three, four, etc. Each carrier member 110 is configured to move independently relative to the housing assembly 400, so that when at least one carrier member 110 is in the retracted position, at least one other carrier member 110 can be in the extended position. In this way, when the user loads a sample onto one of the carrier members 110, the transfer assembly 200 can transfer the sample container 10 from other carrier members 110 in the retracted position, thereby reducing the waiting time of the transfer assembly 200 and helping to improve efficiency.

[0096] Based on the first embodiment, 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 suitable for the carrier 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, when the carrier member 110 is in the retracted position, the sample loading assembly 100 closes the first channel opening 410. In this way, on the one hand, it can further enhance the safety protection of the carrier member 110 and reduce the pollution of the carrier 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 beneficial to forming a temperature-stable incubation environment.

[0097] 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 carrier 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 carrier member 110.

[0098] 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.

[0099] Based on the first embodiment, in some other embodiments of the present invention, the casing assembly 400 has a first channel opening 410, and the shape of the first channel opening 410 is larger than and suitable for allowing the loading member 110 to extend out of or enter the casing assembly 400. For example, the first channel opening 410 is a rectangular channel opening. In this embodiment, the casing assembly 400 further has a cover that is provided independently of the sample loading assembly 100, and this cover can move relative to the main structure of the casing assembly 400 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 pollution, and enhancing heat preservation performance.

[0100] It should be noted that the cover in this embodiment can rotate relative to the main structure of the casing assembly 400 to open or close the first channel opening 410, or can move relative to the main structure of the casing assembly 400 to open or close the first channel opening 410.

[0101] 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.

[0102] Based on the first embodiment, 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 casing 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, so as to realize the sliding of the loading member 110 relative to the casing 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 along a 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 along the first direction, and the first sliding seat 1221 is slidably connected to the first slide rail through a first slider 124. Specifically to Figure 5 、 Figure 6In this case, 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 with reference to the foregoing. The second sliding seat 1222 is connected to the first sliding seat 1221 and can slide relative to the first sliding seat 1221 along a second direction. The carrying member 110 is connected to the second sliding seat 1222. In this way, the carrying member 110 can slide along the first direction and the second direction. For example, a second slide rail 125 is provided on the first sliding seat 1221, and a second slider (not shown) is provided on the second sliding seat 1222. The second sliding seat 1222 is slidably connected to the second slide rail 125 through the second slider. Specifically to Figure 5 , Figure 6 In this case, a second slide rail 125 is provided on the upper side of the first sliding seat 1221, and a second slider is 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.

[0103] In this embodiment, the connection between the foregoing carrying member 110 and the sliding member 122 specifically 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 a first sliding seat 1221, the carrying member 110 and the first sliding seat 1221 are detachably connected. When the sliding member 122 includes a first sliding seat 1221 and a second sliding seat 1222, the carrying member 110 and the second sliding seat 1222 are detachably connected.

[0104] It should be noted that the foregoing 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.

[0105] When the bearing component 110 and the sliding component 122 are detachably connected, in some embodiments of the present invention, the bearing component 110 and the sliding component 122 are also provided with mutually cooperating positioning structures. For example, one of the bearing component 110 and the sliding component 122 is provided with a positioning column, and the other is provided with a positioning hole. When the bearing component 110 is placed on the sliding component 122, the positioning column is inserted into the positioning hole to achieve positioning. For another example, the sliding component 122 is provided with a positioning groove, and the bearing component 110 is placed as a whole in the positioning groove, and is positioned by relying on the contact between the outer side surface of the bearing component 110 and the groove wall of the positioning groove.

[0106] When the bearing member 110 and the sliding member 122 are detachably connected, in some embodiments of the present invention, Figures 7 to 11 The carrying component 110 includes a carrying body 112 and a handle 113 . The carrying body 112 is used to place the sample container 10 . The handle 113 is connected to the carrying body 112 . The user can lift the carrying component 110 through the handle 113 , thereby separating the carrying component 110 from the sliding component 122 .

[0107] The handle 113 includes a connection portion 1131 rotatably connected to the carrier body 112, and a grip portion 1132 for a user to hold. Specifically, the connection portion 1131 includes a rotation axis, and the handle 113 can rotate relative to the carrier body 112 between a lifting position and an initial position around the rotation axis. Figures 7 to 11 In the embodiment shown, 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 may have a curved section or a bent section.

[0108] In this embodiment, the handle 113 can be rotated upward relative to the carrying body 112 to a lifting position, that is, Figure 10 When the handle 113 is in the lifting position, the gripping portion 1132 is higher than the connecting portion 1131, and the center of gravity A of the carrying body 112 (the center of gravity position is indicated by a dotted circle in the figure for ease of understanding) and the gripping portion 1132 are located on the same side of the connecting portion in the horizontal direction. In this way, when the user lifts the carrying component 110, the carrying body 112 can remain stable under the action of its own gravity, so that 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 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.

[0109] 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.

[0110] 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 position, and when the handle 113 is in the initial position, 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.

[0111] 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 column on the carrying body 112, and the limiting column 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.

[0112] 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 position, so as to limit its further rotation. Referring to Figure 11, the second limiting part 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 part 1122 is the groove wall on the other side of the receiving groove 1123.

[0113] Based on the first embodiment, in some embodiments of the present invention, refer to Figure 3 , the microbial detector further includes an information acquisition component 500. The information acquisition component 500 is used to perform information acquisition operations on the sample container 10 or the sample in the sample container 10. The controller is further configured to control the transfer component 200 to transfer the sample container 10 that has completed the information acquisition operation to the incubation component 300.

[0114] When the microbial 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. The rotation angle is usually greater than or equal to 360°. In this embodiment, the rotating part and the bearing part 110 are located in different areas. Therefore, the transfer component 200 needs to first transfer the sample container 10 on the bearing part 110 to the rotating part. After the information acquisition component 500 performs the information acquisition operation, the transfer component 200 then transfers the sample container 10 from the rotating part to the incubation component 300.

[0115] In this embodiment, the controller is configured to control the information acquisition part 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 part can more perfectly 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 rotating part drives the sample container 10 to rotate synchronously, and there is no relative movement between the sample container 10 and the rotating part. Therefore, it is possible to avoid the bottom of the sample container 10 from being worn and affecting transparency, thereby affecting the detection results of the detection component.

[0116] When the information acquisition component 500 further includes a rotating part, in some embodiments of the present invention, the rotating part can 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 part performs information acquisition operations from the side. This method is applicable to the sample container 10 placed vertically.

[0117] Based on the first embodiment, in some embodiments of the present invention, refer to Figure 3, the carrier component 110 can move relative to the housing assembly 400 in a first direction to switch between an extended position and a retracted position. In other words, the carrier component 110 in this embodiment can move in a linear direction, and its moving stroke is short, which helps to reduce the volume of the microorganism detector and helps the carrier component 110 to quickly reach the extended position or the retracted position. Taking Figure 1 , Figure 2 as an example, the first direction is the front-back direction in the figure (the front side refers to the side of the housing assembly 400 with a human-computer interaction access port).

[0118] In this embodiment, along the first direction, the information acquisition component 500 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 carrier component 110 to the information acquisition component 500 and from the information acquisition component 500 to the incubation component 300 with a short stroke.

[0119] When the microorganism detector further includes an information acquisition position and the 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.

[0120] 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 10 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 10 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.

[0121] 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.

[0122] When the microbial 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 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 acquire 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 acquire 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 10, and 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.

[0123] When the microbial 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 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 or 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.

[0124] 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 incorrect test results. 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 blood cells in the blood sample, resulting in possible false positives in the test results. Therefore, before performing blood culture detection on the blood sample, it is necessary to obtain the information on the amount of the blood sample in the sample container 10 (in this implementation scheme, 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 on the amount of the blood sample in the sample container 10 and the detection information of the detection component.

[0125] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
