The clamping mechanism uses a bidirectional threaded rod to drive the movable plate to move synchronously, which can adapt to different specifications of sampling dishes and lofting containers. The fixing and rotating mechanism picks up and rotates the cotton swab to ensure uniform contact between the cotton tip and the sample. The tilting mechanism drives the hinged frame to adjust the angle of the cotton swab through an electric push rod. The cotton swab can complete internal and external transmission through the connecting groove on the side wall of the isolation box, avoiding direct contact by humans. The translation mechanism uses a stepping motor to drive the threaded rod to achieve horizontal positioning, combined with the lifting control of the cylinder, to form a multi-dimensional movement path in a closed environment, significantly reducing the risk of operators being exposed to harmful microorganisms and reducing the harm of harmful microorganism samples to staff during the sampling process.

[0019] 2. Through the coordinated cooperation of the separation mechanism, the collection box and the pushing plate, the driving motor drives the saw teeth to rotate at high speed, accurately cutting the connection between the wooden handle and the cotton tip of the cotton swab. The cotton tip directly falls into the lofting container, and the wooden handle is transferred to the collection box for unified treatment through the translation mechanism, avoiding cross-infection caused by traditional scissors operation, optimizing the detection steps, and further improving the detection efficiency of microorganisms.

[0033] The following further describes in detail the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0034] Example 1:

[0035] As shown in the attached Figure 1 to the attached Figure 11As shown in the figure, the present invention provides a microbial sample detection and sampling device for medical testing, including an isolation box 1. A first fixing frame 2 is fixedly connected to the bottom of the inner wall of the isolation box 1. A sampling dish 3 and a sample placing container 4 are both movably connected to the top of the first fixing frame 2. A clamping mechanism 5 is arranged inside the first fixing frame 2 for clamping and fixing the sampling dish 3 and the sample placing container 4. A cotton swab 6 is arranged inside the isolation box 1 for sampling the microorganisms inside the sampling dish 3. A fixing and rotating mechanism 7 is arranged above the cotton swab 6 for clamping and rotating the cotton swab 6. An inclination mechanism 8 is arranged above the fixing and rotating mechanism 7 for driving the fixing and rotating mechanism 7 to tilt left and right. A translation mechanism 10 is arranged at the top of the inner wall of the isolation box 1 for driving the fixing and rotating mechanism 7 to translate left and right. A cylinder 9 is fixedly installed between the inclination mechanism 8 and the translation mechanism 10 for driving the fixing and rotating mechanism 7 to move up and down. A connecting frame 11 is fixedly connected to the rear side of the inner wall of the isolation box 1. A separating mechanism 12 is arranged inside the connecting frame 11 for cutting the cotton swab 6. A glass plate 101 is arranged on the front side of the isolation box 1. A box door 102 is installed on the outer surface of the glass plate 101 through a hinge. The material of the box door 102 is also glass. Connecting grooves 103 are opened on both the left and right sides of the isolation box 1. A telescopic plate 104 is slidably connected inside the connecting groove 103. A handle 105 is fixedly connected to the outer surface of the telescopic plate 104. Weight plates 201 are fixedly connected to both the left and right sides of the first fixing frame 2. A cover body 30 and a collection box 13 are respectively placed on the tops of the two groups of weight plates 201. A sliding plate 401 is slidably connected inside the sample placing container 4. A push plate 14 is fixedly connected to the outer surface of the lower shell 7013. The cotton swab 6 is made of a wooden handle 601 and a cotton tip 602.

[0036] As can be seen from the above, when it is necessary to sample a volatile and harmful microbial sample, first open the box door 102 and place the sampling dish 3 sealed by the cover 301 and the sample placing container 4 inside the first fixing rack 2, and place the collection box 13 for collecting the wooden handle 601 of the cotton swab 6 on the top of a group of load-bearing plates 201. Then close the box door 102 to make the box door 102 in a sealed state. Then, clamp and fix the sampling dish 3 and the sample placing container 4 through the clamping mechanism 5 to prevent the sampling dish 3 and the sample placing container 4 from shaking during the operation. Then, drive the fixing and rotating mechanism 7 to the top of the sampling dish 3 through the translation mechanism 10, and then rotate the cover 301 of the sampling dish 3 through the cooperation of the cylinder 9 to separate the cover 301 from the sampling dish 3, and place the sampling dish 3 on the top of another group of load-bearing plates 201. Then hold and pull up the left grip 105 to move the telescopic plate 104 upward, and through the translation mechanism 10, the tilting mechanism 8 and the cylinder 9, the fixing and rotating mechanism 7 moves to the outside of the box door 102 through the connecting groove 103. Then, clamp the wooden handle 601 of the cotton swab 6 through the fixing and rotating mechanism 7. Similarly, make the cotton swab 6 enter the isolation box 1. Then pull down the grip 105 to seal the isolation box 1 again, avoiding the staff from inhaling the harmful microbial sample for a long time. Then, through the translation mechanism 10, make the cotton swab 6 reach the upper side of the sampling dish 3, and then make the cotton head 602 uniformly contact the sample in the sampling dish 3 through the cylinder 9 and the fixing and rotating mechanism 7. After driving the sampled cotton swab 6 to move to the top of the sample placing container 4 through the translation mechanism 10 and the cylinder 9, separate the cotton swab 6 through the separating mechanism 12 to make the cotton head 602 fall into the inside of the sample placing container 4. The translation mechanism 10 continues to drive the wooden handle 601 to move to the right until it reaches the top of the collection box 13. Release the wooden handle 601 through the fixing and rotating mechanism 7 to make the wooden handle 601 fall into the inside of the collection box 13. Through the translation mechanism 10 and the cylinder 9, the push plate 14 fixedly connected to the outer surface of the fixing and rotating mechanism 7 pushes the sliding plate 401 to slide leftward to seal the sample placing container 4. Similarly, then clamp the sealed sample placing container 4 through the translation mechanism 10, the cylinder 9 and the fixing and rotating mechanism 7, and take the sealed sample placing container 4 through the right connecting groove 103. Then, seal the sampling dish 3 again through the cover 301. After completely purifying the air in the isolation box 1 through a purification device (not shown in the figure), then open the box door 102 again to take various containers inside the isolation box 1, and complete the entire sampling process of the microbial sample.

[0037] Embodiment 2:

[0038] As shown in the attached Figure 2 to the attached Figure 3As shown in the figure, this embodiment is basically the same as the previous one, except that the clamping mechanism 5 includes an L-shaped mounting plate 501 fixedly connected to the right side of the first fixing frame 2. A first stepping motor 502 is fixedly installed on the outer side of the vertical plate of the L-shaped mounting plate 501. The output end of the first stepping motor 502 extends to the inner side of the vertical plate of the L-shaped mounting plate 501 and is fixedly connected to a driving wheel 503. The driving wheel 503 is drivingly connected to a driven wheel 505 through a belt 504. Both the front and rear sides inside the first fixing frame 2 are rotatably connected to a rotating rod 506. Two sets of opposite thread grooves 507 are formed on the outer surface of the rotating rod 506. The rotating rod 506 is threadedly connected to a first movable plate 508 and a second movable plate 509 through the two sets of thread grooves 507 respectively. There are two first movable plates 508 and two second movable plates 509, and they are respectively located on the opposite sides of the two sets of opposite thread grooves 507. One end of both sides of the rotating rod 506 extends to the outside of the first fixing frame 2 and is respectively fixedly connected to the driving wheel 503 and the driven wheel 505.

[0039] As can be seen from the above, when the sampling dish 3 and the sample placing container 4 are fixed, the first stepping motor 502 is turned on. The first stepping motor 502 drives the driving wheel 503 to rotate, and through the belt 504, the driven wheel 505 rotates synchronously. The driving wheel 503 and the driven wheel 505 drive the rotating rods 506 on both sides to rotate, so that the two first movable plates 508 and the second movable plates 509 approach each other, thereby fixedly clamping the sampling dish 3 and the sample placing container 4.

[0040] Embodiment 3:

[0041] As shown in the attached Figure 5 to the attached Figure 6As shown, this embodiment is basically the same as the previous one, except that the fixing and rotating mechanism 7 includes a housing 701, which is composed of a connecting plate 7011, an upper housing 7012 and a lower housing 7013. The upper housing 7012 is fixedly connected to the top of the connecting plate 7011, and the lower housing 7013 is arranged on the lower side of the connecting plate 7011. A driving motor 702 is fixedly installed at the top of the inner wall of the upper housing 7012. The output end of the driving motor 702 is fixedly connected to a gear 703. A gear 704 is meshed with the outer surface of the gear 703. The bottom of the gear 704 is fixedly connected to a connecting column 705. The connecting column 705 extends to the lower side of the connecting plate 7011 and is fixedly connected to the lower housing 7013 by bolts. A stepping motor 706 is also fixedly installed at the top of the inner wall of the upper housing 7012. The output end of the stepping motor 706 is fixedly connected to a worm 707 through a flange. One end of the worm 707 away from the stepping motor 706 is rotatably connected to the bottom of the inner wall of the upper housing 7012. Two fixing blocks 708 are fixedly connected to the rear side of the inner wall of the upper housing 7012. A rotating column 709 is rotatably connected between the two fixing blocks 708. A worm gear 710 is fixedly connected to the outer surface of the rotating column 709. The worm 707 is meshed with the worm gear 710. A gear 711 is also fixedly connected to the outer surface of the rotating column 709. A movable sleeve 712 is movably connected to the outer surface of the connecting column 705. One end of the movable sleeve 712 away from the gear 704 penetrates through the connecting plate 7011 and extends into the interior of the lower housing 7013. The gear 711 is meshed with the movable sleeve 712. A double-headed lead screw 714 is rotatably connected to the left and right inner walls of the lower housing 7013. A gear 713 is fixedly connected to the middle of the double-headed lead screw 714. The gear 713 is meshed with the movable sleeve 712. Nut seats 715 are threadedly connected to the opposite sides of the double-headed lead screw 714. Connecting plates 716 are fixedly connected to the outer surfaces of the nut seats 715. One ends of the connecting plates 716 away from the nut seats 715 extend to the lower side of the housing 701 and are fixedly connected to clamping plates 717.

[0042] As described above, the fixing and rotating mechanism 7 can clamp and rotate the cover 301 and the cotton swab 6. When in use, the second stepping motor 706 is turned on. The second stepping motor 706 drives the worm 707 to rotate, and then the worm gear 710 rotates. The rotation of the worm gear 710 drives the rotating column 709 to rotate, thereby driving the third gear 711 to rotate. When the third gear 711 rotates, it drives the movable sleeve 712 connected in mesh to slide on the outer surface of the connecting column 705, causing the fourth gear 713 connected in mesh to rotate. When the fourth gear 713 rotates, it drives the double-headed lead screw 714 to rotate, and then drives the connecting plates 716 to approach or move away from each other through the nut seats 715, so that the clamping plates 717 clamp components such as the cover 301 or the cotton swab 6. Then, the first driving motor 702 is turned on. The first driving motor 702 drives the first gear 703 to rotate, causing the second gear 704 connected in mesh to rotate. When the second gear 704 rotates, it drives the connecting column 705 to rotate, thereby driving the lower housing 7013 to rotate. When the lower housing 7013 rotates, it can drive components such as the cover 301 or the cotton swab 6 to rotate. This can not only make the cotton tip 602 rotate in the sampling dish 3 to evenly contact the sample in the sampling dish 3, but also open the cover 301 of the sampling dish 3 or reseal the sampling dish 3 through the cover 301 again, improving the sampling quality and efficiency of microorganisms.

[0043] Embodiment 4:

[0044] As shown in the Figure 8 accompanying drawings, this embodiment is basically the same as the previous embodiment, except that the tilting mechanism 8 includes two straight plates 801. Hinge frames 802 are fixedly connected to the sides of the two straight plates 801 that are close to each other. The two hinge frames 802 are movably connected by a connecting rod 803. An electric push rod 804 is movably installed at the bottom of one straight plate 801, and the extending end of the electric push rod 804 is movably connected to the top of the other straight plate 801.

[0045] As described above, when cooperating with the fixing and rotating mechanism 7 to fix it to the outer cotton swab 6 through the connection slot 103, the electric push rod 804 is turned on. The extending end of the electric push rod 804 drives one side of one of the straight plates 801 to move downward. With the cooperation of the hinge frame 802 and the connecting rod 803, the fixing and rotating mechanism 7 is tilted, so that one side of the fixing and rotating mechanism 7 can smoothly pass through the connection slot 103, assisting the fixing and rotating mechanism 7 to complete the fixed clamping of the cotton swab 6.

[0046] Embodiment 5:

[0047] As shown in the Figure 10As shown in the figure, this embodiment is basically the same as the previous one. The difference is that the translation mechanism 10 includes a second fixed frame 1001. A first threaded rod 1002 is rotatably connected inside the second fixed frame 1001. A third stepper motor 1003 is fixedly installed on the right side of the second fixed frame 1001. The output end of the third stepper motor 1003 extends into the second fixed frame 1001 and is fixedly connected to one end of the first threaded rod 1002. Two fixed rods 1004 are fixedly connected inside the second fixed frame 1001. The two fixed rods 1004 are symmetrically distributed on the front and rear sides of the first threaded rod 1002.

[0049] Embodiment Six:

[0050] As shown in the appendix Figure 11 As shown in the figure, this embodiment is basically the same as the previous one. The difference is that the separation mechanism 12 includes a mounting seat 1201 slidably connected inside the connecting frame 11. A second threaded rod 1202 is also rotatably connected inside the connecting frame 11. The second threaded rod 1202 is threadedly connected to the mounting seat 1201. A third driving motor 1203 is fixedly installed on the right side of the connecting frame 11. The output end of the third driving motor 1203 extends into the connecting frame 11 and is fixedly connected to one end of the second threaded rod 1202. A bearing plate 1204 is fixedly connected to the front side of the mounting seat 1201. A fourth driving motor 1205 is fixedly installed on the top of the bearing plate 1204. The output end of the fourth driving motor 1205 extends to the lower side of the bearing plate 1204 and is quickly disassembled and assembled with a sawtooth 1206.

[0051] As can be seen from the above, when separating the cotton swab 6, the cylinder 9 is used to make the connection between the wooden handle 601 and the cotton tip 602 be at the same horizontal line as the saw teeth 1206. When the translation mechanism 10 drives the cotton swab 6 to be perpendicular to the laying container 4, the third driving motor 1203 is turned on. The third driving motor 1203 drives the second threaded rod 1202 to rotate, causing the mounting seat 1201 to slide leftward within the connecting frame 11. During this process, the fourth driving motor 1205 is turned on. The fourth driving motor 1205 drives the saw teeth 1206 to rotate, and through the cooperation of the bearing plate 1204, the saw teeth 1206 cut the connection between the wooden handle 601 and the cotton tip 602, thereby completing the separation of the wooden handle 601 and the cotton tip 602 in the cotton swab 6 and improving the resource utilization rate.
