[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Combine the following Figure 1-Figure 3 , the sample injection control device and the commercial sterility detection station provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0040] In the first aspect, Figure 1As shown, the embodiment of the utility model provides a sampling control device, including: an unlocking mechanism 1 and an opening and closing mechanism 2; the unlocking mechanism 1 is used to press the cover opening button on the sampling tray 102 to trigger the unlocking of the tray cover 1021 and the tray body 1022 of the sampling tray 102;

[0041] The opening and closing mechanism 2 includes a driving component 21 and a working head 22, wherein the driving component 21 and the working head 22 are connected, and the working head 22 is used to connect to the disk cover 1021; wherein the driving component 21 is used to control the disk cover 1021 to flip between a closed state and an open state relative to the disk body 1022 through the working head 22.

[0042] It is understandable that the injection control device is applied to a commercial sterility detector 10, which has a detector body 101, and a sample injection tray 102 is provided at the injection port of the detector body 101. The sample injection tray 102 can switch between a first state extending out of the injection port and a second state retracted into the injection port.

[0043] Furthermore, the sample tray 102 includes a tray body 1022 and a tray cover 1021, wherein the tray cover 1021 is used to cover the upper side of the tray body 1022, and one side of the tray cover 1021 is rotatably connected to one side of the tray body 1022. A receiving groove is provided on the upper surface of the tray body 1022, and the receiving groove is used to receive consumables 20, and the consumables 20 include microplates, waste discharge plates, etc. Among them, a locking assembly is provided between the tray body 1022 and the tray cover 1021, and the locking assembly is connected to the cover opening button on the tray body 1022 by power coupling, and a plurality of through holes are provided on the tray cover 1021, and the plurality of through holes are arranged one by one opposite to the plurality of detection positions on the consumables 20 for containing samples.

[0044] When the cover opening button receives a press trigger from the unlocking mechanism 1, the locking assembly is in the unlocking state, the locking connection between the disk body 1022 and the disk cover 1021 is released, and the disk cover 1021 can be controlled by the opening and closing mechanism 2 to switch from the closed state to the open state.

[0045] When the opening and closing mechanism 2 controls the disk cover 1021 to return from the open state to the closed state, by releasing the pressure of the unlocking mechanism 1 on the open cover button, for example, controlling the unlocking mechanism 1 to separate from the open cover button, the locking assembly can be switched from the unlocked state to the locked state, and the locking connection between the disk body 1022 and the disk cover 1021 is restored.

[0046] In some examples, the unlocking mechanism 1 may adopt a mechanical arm and other driving structures, as long as it can achieve pressing the cover opening button and separating from the cover opening button.

[0047] In some examples, the driving component 21 of the opening and closing mechanism 2 can adopt a robotic arm and other driving structures, and the working head 22 can use a clamp or an electric magnetic head according to the structure and material properties of the disk cover 1021 to conveniently control the connection or separation of the working head 22 and the disk cover 1021.

[0048] For the sample injection control device shown in this embodiment, by configuring the unlocking mechanism 1 and the opening and closing mechanism 2, in the process of commercial sterility testing of the sample, the unlocking mechanism 1 can be used to press the cover opening button on the sample injection tray 102 to trigger the unlocking of the tray cover 1021 and the tray body 1022 of the sample injection tray 102, and then the driving component 21 of the opening and closing mechanism 2 controls the working head 22 to connect with the tray cover 1021, and controls the tray cover 1021 to switch from a closed state to an open state; after the consumable 20 containing the sample is placed into the tray body 1022, the driving component 21 controls the tray cover 1021 to switch from an open state to a closed state through the working head 22; finally, the unlocking mechanism 1 is controlled to separate from the cover opening button, so as to realize the automatic loading of the consumable 20 into the sample injection tray 102, thereby facilitating the subsequent commercial sterility testing.

[0049] From the above, it can be seen that the utility model is convenient for assisting the commercial sterility testing instrument 10 to perform automated testing in a sterile environment. The entire testing process does not require human participation, and there is no need to consider the requirements of traditional testing methods on the number of testing personnel and the operating level. It not only improves the testing efficiency, but also effectively reduces the waste of personnel resources caused by human participation in testing. While reducing the testing cost, it ensures the accuracy of the commercial sterility test results.

[0050] In some embodiments, Figure 2 As shown, the unlocking mechanism 1 includes a first telescopic driving member 11 and a pressing member 12; the first telescopic driving member 11 and the pressing member 12 are connected to drive the pressing member 12 to move between a first position and a second position;

[0051] When the pressing member 12 is in the first position, the pressing member 12 contacts the cover-opening button to press the cover-opening button; when the pressing member 12 is in the second position, the pressing member 12 and the cover-opening button are separated.

[0052] It is understandable that, in actual application, upon receiving an instruction for the consumable 20 (e.g., microplate) to enter the sample tray 102, the first telescopic driving member 11 drives the pressing member 12 to move to the first position to press the cover opening button, triggering the unlocking of the tray cover 1021 and the tray body 1022 of the sample tray 102. When it is determined that the consumable 20 (e.g., microplate) is loaded into the tray body 1022 and the tray cover 1021 is in the closed state, the first telescopic driving member 11 drives the pressing member 12 to return from the first position to the second position.

[0053] The first telescopic driving member 11 may be a cylinder or an electric push rod. In order to facilitate pressing the cover opening button at a set height, the first telescopic driving member 11 is horizontally arranged and is configured to be installed on the first adjustment bracket 13. The first adjustment bracket 13 adjusts the height of the first telescopic driving member 11 in the vertical direction, and then the first telescopic driving member 11 drives the pressing member 12 to move between the first position and the second position in the horizontal direction, so as to press the cover opening button or separate from the cover opening button.

[0054] Optionally, the first adjustment bracket 13 includes a first screw assembly and a first mounting plate; the first screw assembly includes a plurality of vertically arranged screws, and the plurality of screws are installed side by side on the workbench, and the first mounting plate is used to install a horizontally arranged first telescopic drive member 11, and the first mounting plate is threadedly connected to the plurality of screws respectively, so that the first mounting plate can be adjustably arranged above the workbench in the vertical direction, and then the first mounting plate adjusts the first telescopic drive member 11 to a height suitable for the cover opening button.

[0055] Optionally, the first telescopic driving member 11 is connected to the pressing member 12 through an "L"-shaped bracket. The "L"-shaped bracket includes a vertical rod and a horizontal rod. The vertical rod and the horizontal rod are vertically connected. The telescopic end of the first telescopic driving member 11 is connected to the vertical rod of the "L"-shaped bracket, and the horizontal rod of the "L"-shaped bracket is connected to the pressing member 12.

[0056] Furthermore, the horizontal rod of the "L"-shaped bracket is movably disposed on the first telescopic driving member 11, and the first telescopic driving member 11 provides support for the horizontal rod and the pressing member 12. This design is beneficial for controlling the pressing member 12 to move smoothly in the horizontal direction, and is beneficial for providing protection for the first telescopic driving member 11, thereby ensuring the service life of the first telescopic driving member 11.

[0057] In some embodiments, the pressing member 12 includes a first pressing block and a second pressing block; the telescopic end of the first telescopic driving member 11 is connected to the first end of the first pressing block, and the second end of the first pressing block is connected to the first end of the second pressing block; the first pressing block and the second pressing block are both extended along the telescopic direction of the first telescopic driving member 11, and the second pressing block is located at the lower side of the first pressing block.

[0058] It is understandable that when the pressing member 12 is in the first position, the second end of the first pressing block contacts the cover opening button, and the second pressing block presses on the disk body 1022. Since the second end of the first pressing block contacts the cover opening button, the cover opening button can be pressed, thereby releasing the locking connection between the disk body 1022 and the disk cover 1021. In the process of the opening and closing mechanism 2 controlling the disk cover 1021 to switch from the closed state to the open state, the second pressing block presses on the disk body 1022, thereby ensuring the stability of the disk body 1022 in this process.

[0059] Among them, a socket can be constructed on the disk body 1022, and the socket is located below the cover opening button. This design makes it easy to ensure that the second pressure block is inserted into the socket, so that when the disk body 1022 is pressed, the first pressure block can perform the pressing operation of the cover opening button.

[0060] Correspondingly, when the pressing member 12 is in the second position, the second end of the first pressing block is separated from the cover opening button, and the second pressing block is separated from the disk body 1022 to release the pressing on the disk body 1022 .

[0061] In some embodiments, Figure 1 and Figure 2 As shown, in order to facilitate the pressing control of the cover opening button, a first telescopic driving member 11 can be set to drive the pressing member 12 to move along a first direction, and the first direction is parallel to the rotation axis of the disk cover 1021 relative to the disk body 1022.

[0062] In some embodiments, Figure 1 As shown, the driving assembly 21 includes a second telescopic driving member 211 and a flip driving member 212; the second telescopic driving member 211 is connected to the flip driving member 212, and the flip driving member 212 is connected to the working head 22; the second telescopic driving member 211 is used to drive the flip driving member 212 to drive the working head 22 to approach or move away from the disk cover 1021; the flip driving member 212 is used to drive the working head 22 to flip between the third position and the fourth position;

[0063] When the working head 22 is in the third position, the working head 22 controls the disk cover 1021 to be in a closed state; when the working head 22 is in the fourth position, the working head 22 controls the disk cover 1021 to be in an open state.

[0064] It is understandable that the second telescopic driving member 211 can be a cylinder or an electric push rod. In order to facilitate the control of the connection between the working head 22 and the plate cover 1021 of the sample tray 102, the second telescopic driving member 211 is horizontally arranged and is configured to be installed on the second adjustment bracket 23. The second adjustment bracket 23 adjusts the height of the second telescopic driving member 211 in the vertical direction, and then the second telescopic driving member 211 drives the flip driving member 212 to drive the working head 22 to approach or move away from the plate cover 1021. Among them, the second adjustment bracket 23 is similar to the first adjustment bracket 13, and no further description is given.

[0065] At the same time, after the working head 22 is connected to the disk cover 1021 of the sample tray 102, the working head 22 can be controlled to flip around the rotation axis of the disk cover 1021 through the flipping drive 212 to control the disk cover 1021 to be between the closed state and the open state relative to the disk body 1022.

[0066] Optionally, in order to facilitate control of the connection or separation of the working head 22 and the disk cover 1021 , the working head 22 is provided with a bayonet, and the bayonet is used to be clamped on both sides of the disk cover 1021 along the thickness direction of the disk cover 1021 .

[0067] Specifically, the working head 22 includes a first clamping plate and a second clamping plate. The first clamping plate is connected to the flip driving member 212 . A clamping slot is formed between the first clamping plate and the second clamping plate. The gap width of the clamping slot is greater than or equal to the thickness of the disk cover 1021 .

[0068] In practical applications, the snap-in on the working head 22 and the disk cover 1021 can be snapped into or separated from each other by controlling the second telescopic driving member 211 to be extended and retracted in the horizontal direction.

[0069] In some embodiments, Figure 3 As shown, the flip driving member 212 includes a connecting seat 2121, a third telescopic driving member 2122, a crank arm 2123 and a connecting rod 2124;

[0070] The connecting seat 2121 is connected to the second telescopic driving member 211, the third telescopic driving member 2122 is arranged on the connecting seat 2121, one end of the connecting rod 2124 is rotatably connected to the connecting seat 2121, and the other end is rotatably connected to the first end of the crank arm 2123; the telescopic end of the third telescopic driving member 2122 is rotatably connected to the crank arm 2123, and the second end of the crank arm 2123 is connected to the working head 22;

[0071] The third telescopic driving member 2122 is used to drive the crank arm 2123 to rise and fall, and the crank arm 2123 is used to rotate relative to the telescopic end of the third telescopic driving member 2122 under the limitation of the connecting rod 2124, thereby driving the working head 22 to perform a flipping movement.

[0072] Specifically, the crank arm 2123 and the connecting rod 2124 are arranged on the upper side of the connecting seat 2121, and the third telescopic driving member 2122 is vertically arranged and located on the lower side of the connecting seat 2121; the rotation axis between the connecting rod 2124 and the connecting seat 2121, the rotation axis between the crank arm 2123 and the connecting rod 2124, and the rotation axis between the third telescopic driving member 2122 and the crank arm 2123 are respectively parallel to the rotation axis of the disk cover 1021 relative to the disk body 1022.

[0073] In actual application, after the unlocking mechanism 1 presses the cover opening button, the second telescopic driving member 211 controls the working head 22 to move toward the side close to the sample tray 102 until the working head 22 is in the third position, at which time the working head 22 is connected to the tray cover 1021 of the sample tray 102;

[0074] Next, the third telescopic driving member 2122 drives the crank arm 2123 to rise, and the crank arm 2123 drives the working head 22 to turn over along the first rotation direction under the limitation of the connecting rod 2124 until the working head 22 is in the fourth position, at which time the tray cover 1021 switches from the closed state to the open state;

[0075] After the consumables 20 (e.g., microplate) are loaded into the tray body 1022, the third telescopic driving member 2122 drives the crank arm 2123 to descend, and the crank arm 2123 drives the working head 22 to flip along the second rotation direction under the limitation of the connecting rod 2124 until the working head 22 returns to the third position, at which time the tray cover 1021 switches from the open state to the closed state;

[0076] Finally, the second telescopic drive member 211 controls the working head 22 to move toward the side away from the sample tray 102 until the working head 22 and the tray cover 1021 of the sample tray 102 are separated, and then controls the unlocking mechanism 1 to separate from the cover opening button, thereby completing the automatic loading of the consumables 20 (such as a microplate).

[0077] Based on the solution of the above embodiment, in order to reduce the space occupied, the unlocking mechanism 1 and the opening and closing mechanism 2 are arranged side by side and are configured to be arranged on the same side of the sample feeding tray 102 .

[0078] For example, when the cover opening button is located on the left side of the sample tray 102 along the first direction, the unlocking mechanism 1 and the opening and closing mechanism 2 can be arranged side by side on the left side of the sample tray 102. The first direction is the direction in which the tray cover 1021 is parallel to the rotation axis of the tray body 1022.

[0079] In the second aspect, Figure 1 As shown, the embodiment of the utility model also provides a commercial sterility testing station, including: a commercial sterility testing instrument 10 and the sample injection control device as described above;

[0080] The commercial sterility testing instrument 10 has a sampling port and a sampling tray 102 adapted to the sampling port. The sampling tray 102 can switch between a first state extending out of the sampling port and a second state retracted into the sampling port. The sampling control device is arranged on one side of the commercial sterility testing instrument 10 and is arranged opposite to the sampling tray 102 in the first state.

[0081] It is understandable that since the commercial sterility testing station includes an injection control device, the specific structure of the injection control device refers to the above embodiment, and the commercial sterility testing station of this embodiment includes all the technical solutions of the above embodiment, and therefore at least has all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be described one by one.

[0082] Among them, the commercial sterility testing station has a testing room, which is equipped with an independent temperature and humidity adjustment mechanism. The commercial sterility testing instrument 10 and the above-mentioned sampling control device are arranged in the testing room. An ultraviolet lamp is arranged on the top of the testing room. The ultraviolet lamp is used to perform ultraviolet sterilization on the internal environment of the testing room to ensure that all testing work in the testing room is in a sterile environment.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
