Description

Technical Field

[0001] This invention relates to the field of HIV sampling and testing, and in particular to a device for on-site HIV sampling and sample transport. Background Technology

[0002] AIDS is caused by infection with the human immunodeficiency virus (HIV) and is a highly dangerous infectious disease. Currently, the method for on-site sampling of HIV-infected patients involves collecting blood or bodily fluid samples from the patient using test tubes. The collected test tubes are then sealed and transported to a testing laboratory for analysis. However, commonly used testing instruments with storage devices typically expose the upper half of the test tube to facilitate sample introduction. However, if a foreign object impacts or shakes the test tube, it can easily detach or damage the tube, requiring manual cleaning by staff.

[0003] With the advancement of technology, technicians in related fields have optimized the process of HIV sampling and sample transportation. To make more accurate comparisons, Chinese Patent No. CN117049001A discloses a device for on-site HIV sampling and sample transportation, including a testing box, a fixing block, a placement hole, a sliding port, a test tube, and a placement mechanism. In use, the test tube is inserted into the placement hole and the retaining ring, and then the test tube is driven to continue to move down to the bottom of the placement slot to complete the placement of the test tube. Then, the downward connecting rod drives the transmission plate, retaining ring, fixing rod, and transmission long plate to move downward. The transmission long plate pulls down the cover plate, causing the cover plate to rotate and cover the upper end of the test tube.

[0004] However, the following problems still exist when using the above-mentioned existing technology to store and transport sampling tubes:

[0005] 1. When storing and positioning test tubes using the above-mentioned device, staff need to use both hands to place the test tubes on or remove them from the placement mechanism. However, staff cannot always free their hands to position or remove the test tubes during on-site collection. Therefore, when any staff member is holding other objects, it is difficult to place or remove the test tubes using only one hand, thus affecting the efficiency of on-site collection.

[0006] 2. Before placing the test tube containing the sample onto the placement mechanism, the above-mentioned device assists the staff in determining whether a test tube is placed in the placement hole by detecting the closed and open state of the cover plate inside the detection box. However, during use, since the cover plate is tilted upwards and set to the open state, the staff can easily accidentally touch other cover plates and close them while placing the test tube into the placement hole. If the staff does not open the closed cover plate at this time, it will interfere with the subsequent staff's judgment. If the closed cover plate is opened, it will take time, thus affecting the efficiency of on-site collection.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing methods for storing and transporting sample tubes. Summary of the Invention

[0008] To address the aforementioned problems, the present invention provides an on-site HIV sampling and sample transport device, comprising a storage box with an internal hollow structure. The storage box contains a partition plate and a mounting support plate arranged sequentially from top to bottom. The mounting support plate is equipped with a limiting member at its upper limit for limiting the sampling test tubes placed in the storage box. A drive end connected to the limiting member is also provided on the mounting support plate.

[0009] Preferably, the limiting component includes a plurality of limiting frames located on the upper side of the mounting support plate inside the storage box. The limiting frames are arranged in a U-shape, and one horizontal section is connected to the drive end. An arc-shaped sleeve is provided on one of the horizontal sections on the upper side of the limiting frame, and an arc-shaped positioning groove is formed on another horizontal section of the limiting frame. A sliding push plate is connected to the upper limit of the vertical section of the limiting frame, and a through hole is provided on the sliding push plate that is concentric with the arc-shaped sleeve and the positioning groove.

[0010] Preferably, the sliding push plate is hollow inside, and sliding side plates are symmetrically arranged inside the sliding push plate. A guide slide rod is symmetrically arranged between the two sliding side plates, and a retraction spring is sleeved on the guide slide rod located between the two sliding side plates.

[0011] Preferably, the arc-shaped sleeve has an arc-shaped groove, and a plurality of arc-shaped abutments are circumferentially connected to the arc-shaped groove. A clamping spring is provided between the arc-shaped abutments and the inner wall of the arc-shaped groove.

[0012] Preferably, an extension rod extends out of the sliding push plate and moves away from the inner wall of the storage box. A guide push block is provided at one end of the extension rod that is placed in the connected sliding push plate. Slave blocks are symmetrically arranged in the sliding push plate on both sides of the guide push block.

[0013] Preferably, the drive end includes at least two synchronous pulleys symmetrically arranged on the mounting support plate, with a synchronous belt connecting the two synchronous pulleys, and the synchronous belt and all the limit frames are connected together for limiting.

[0014] Preferably, one of the synchronous pulleys is connected to a drive rod that extends downward through a mounting support plate at its center. A support plate is fitted on the drive rod, and the end of the support plate near the limit frame is set as an inclined section. The inclined section is used in conjunction with the extension rod so that the opposing extension rod can slide along its inclined surface.

[0015] Preferably, the drive lever includes a rotating bar passing through the middle of the synchronous pulley, the rotating bar passing downward through a mounting support plate and a guide frame plate, a sliding bar inserted on the rotating bar, and the sliding bar and the rotating bar being limited and connected by a number of circumferentially distributed anti-rotation blocks. The synchronous pulley has a locking groove adapted to the anti-rotation blocks. After the sliding bar and the anti-rotation blocks are inserted into the synchronous pulley, the synchronous pulley is driven to rotate, and the supporting slide plate is sleeved on the sliding bar.

[0016] Preferably, the partition plate is provided with a limiting sleeve that is concentric with the sliding bar and has an opening facing downward. A spiral groove is provided inside the limiting sleeve, and a synchronous protrusion connected to the sliding bar is slidably inserted into the spiral groove. An adjusting spring is provided between the upper ends of the limiting sleeve and the sliding bar.

[0017] Preferably, the mounting support plate is provided with a guide frame plate located on the lower side of all the limiting frames, and the limiting sleeve is provided with an anti-rotation frame for limiting the support slide plate.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] I. This invention uses a synchronous belt to drive a limiting frame to move within the storage box, sequentially causing one of the empty test tubes located below the sealing plate to pass through the plate. This facilitates the introduction of collected samples into the test tube, saving the time required for staff to search for empty test tubes within the storage box, and effectively improving the efficiency of sample collection.

[0020] Second, this invention uses a synchronous belt to drive the test tube containing the collected sample to move within the storage box, while simultaneously moving the empty test tube to correspond to the opening on the partition plate. This eliminates the need for staff to check and place the test tube containing the collected sample, and also facilitates the collection of the next empty test tube, effectively improving the efficiency of sample collection.

[0033] The following is in conjunction with the appendix Figure 1 To be continued Figure 10 The embodiments of the present invention will be described in detail, but the present invention may be implemented in many different ways as defined and covered by the claims.

[0034] This application discloses an on-site HIV sampling and sample transport device. The device is primarily used during on-site sampling of patients, facilitating the transfer of collected patient samples into test tubes. Specifically, when transferring samples into test tubes, staff do not need to deliberately search for empty spaces to store the samples for subsequent transport. Furthermore, after sample collection and transport to the laboratory, the device also facilitates the removal of the test tubes containing the samples.

[0035] Reference Figure 1 and Figure 2 As shown, an on-site HIV sampling and sample transport device includes a storage box 1, a partition plate 10, a mounting support plate 11, a limiting member 2, and a drive end 3. The storage box 1 is hollow inside, and the partition plate 10 and the mounting support plate 11 are arranged sequentially from top to bottom inside the storage box 1. The mounting support plate 11 has an opening, and a cover plate is detachably installed at the top of the storage box 1 to close and seal the storage box 1, thereby facilitating the subsequent transport of the collected test tubes. The upper limit of the mounting support plate 11 is provided with a limiting member 2 to limit the sampling test tubes placed in the storage box 1. The drive end 3, connected to the limiting member 2, is also provided on the mounting support plate 11. In use, the drive end 3 drives the limiting member 2 to slide within the storage box 1, and the limiting member 2 moves the test tubes it limits to correspond to the opening, thereby facilitating the introduction of the collected samples into the test tubes for subsequent transport.

[0036] Reference Figure 2 and Figure 3 As shown, the limiting component 2 is used to limit the sampling tube placed in the storage box 1. Specifically, the limiting component 2 includes a limiting frame 20, an arc-shaped sleeve 21, and a sliding push plate 22. Several limiting frames 20 are provided in the storage box 1 located on the upper side of the mounting support plate 11. The limiting frame 20 is arranged in a U-shape, and one of its horizontal sections is connected to the drive end 3. An arc-shaped sleeve 21 is provided on one of the horizontal sections located on the upper side of the limiting frame 20. An arc-shaped positioning groove is formed on another horizontal section of the limiting frame 20. The sliding push plate 22 is connected to the upper limit of the vertical section of the limiting frame 20. A through hole is provided on the sliding push plate 22, which is concentric with the arc-shaped sleeve 21 and the positioning groove.

[0037] In use, the test tube is driven into the limiting frame 20. During the insertion process, the test tube passes through the arc-shaped sleeve 21 and the through hole on the sliding push plate 22 until its bottom is placed on the horizontal section under the limiting frame 20. The limiting sleeve on the limiting frame 20, the through hole on the sliding push plate 22 and the positioning groove on the lower side of the limiting frame 20 are used to position and clamp the inserted test tube, thereby achieving the effect of limiting and installing the test tube after sample collection in the storage box 1.

[0038] Reference Figure 3 and Figure 4 As shown, the sliding push plate 22 is hollow inside, and sliding side plates 220 are symmetrically arranged inside the sliding push plate 22. Guide slide rods 221 are symmetrically arranged between the two sliding side plates 220. The guide slide rods 221 are connected to one of the sliding side plates 220 and simultaneously slide through the other sliding side plate 220. A contraction spring 222 located between the two sliding side plates 220 is sleeved on the guide slide rod 221. When the guide slide rod 221 moves, it drives the sliding side plate 220 connected to it to move, and simultaneously slides axially on the other sliding side plate 220. After the sliding side plate moves, it stretches the contraction spring 222 connected to it. The contraction of the contraction spring 222 drives the two sliding side plates 220 to continue sliding towards each other.

[0039] In use, when the test tube is inserted into the through hole on the sliding push plate 22, the test tube pushes the two sliding side plates 220 inside the sliding push plate 22 to slide away from each other. When the sliding side plates 220 slide, they slide along the outer side of the connected guide slide rod 221. The sliding side plates 220 connected to the guide slide rod 221 also drive the guide slide rod 221 to slide in the same direction. The two sliding side plates 220 stretch the contraction spring 222 in their respective sliding directions, so that the contraction spring 222 between the two sliding side plates 220 is stretched to both sides. After the contraction spring 222 is stretched, it needs to return to its normal extended state, which drives the two sliding side plates 220 connected at both ends to slide and reset in the direction of approaching each other, so that the two sliding side plates 220 simultaneously press against the outer surface of the test tube.

[0040] Furthermore, the two sliding push plates 22 within the same sliding push plate 22 have symmetrically distributed "V"-shaped structures at their opposite ends. The sliding side plate 220 is symmetrically connected with limiting slide rods that are slidably inserted into the sliding push plate 22. In use, the openings at the opposite ends of the two sliding push plates 22 symmetrically press against the outer surface of the test tube, thereby automatically limiting the test tube within the sliding push plate 22 and keeping it concentric with the through hole and vertical. The movement of the sliding side plate 220 drives the connected limiting slide rods to slide horizontally within the sliding push plate 22.

[0041] Reference Figure 4As shown, an arc-shaped groove is provided inside the arc-shaped sleeve 21. Several arc-shaped abutments 210 are circumferentially connected inside the arc-shaped groove. A clamping spring 211 is provided between the arc-shaped abutments 210 and the inner wall of the arc-shaped groove. In use, as the test tube is inserted downward into the arc-shaped sleeve 21, the test tube comes into contact with the arc-shaped abutments 210 distributed circumferentially inside the arc-shaped sleeve 21. This pushes all the arc-shaped abutments 210 to slide away from the test tube, and compresses the clamping spring 211 connected to the arc-shaped abutments 210. After being compressed, the clamping spring 211 needs to reset, so it provides the connected arc-shaped abutments 210 with an elastic reset force that always slides closer to the test tube, thereby abutting against the outer surface of the test tube and achieving the effect of positioning and clamping the upper outer surface of the test tube.

[0042] Furthermore, to increase the friction between the arc-shaped abutment 210 and the sliding push plate 22 and the outer surface of the test tube, and to avoid damage to the test tube due to hard contact between the arc-shaped abutment 210 and the sliding push plate 22 and the test tube, a sponge pad is connected to the V-shaped opening section of the sliding push plate 22 and the upper limit of the arc-shaped abutment 210. Due to the porous structure and softness of the sponge pad, when the arc-shaped abutment 210 and the sliding push plate 22 are pressed against the outer surface of the test tube, the sponge pad itself undergoes elastic deformation and absorbs the impact force, thereby reducing the pressing force applied to the test tube and preventing the test tube from being damaged due to excessive impact stress. At the same time, after the sponge pad undergoes elastic deformation, part of the test tube is embedded in the sponge pad, forming the effect of the sponge pad wrapping the test tube, thereby increasing the contact area between the sponge pad and the outer surface of the test tube and increasing the friction.

[0043] Reference Figure 3 and Figure 4 As shown, an extension rod 223 extends out of the sliding push plate 22 and moves away from the inner wall of the storage box 1. A guide push block 224 is provided at one end of the extension rod 223 which is located in the connected sliding push plate 22. Slave blocks 225 are symmetrically arranged in the sliding push plate 22 on both sides of the guide push block 224. In use, the extension rod 223 is driven to slide deeper into the sliding push plate 22. The movement of the extension rod 223 drives the connected guide push block 224 to move synchronously. After the guide push block 224 moves to engage with the driven block 225, the extension rod 223 is driven to move deeper into the sliding push plate 22. The movement of the extension rod 223 drives the guide slider to move, and pushes the driven block 225 to slide away from each other through the inclined surfaces on both sides of the guide slider, until the driven block 225 is inserted into the guide slide rod 221. By limiting the movement of the driven block 225 and the guide slide rod 221, the sliding range of the two sliding push plates 22 on the guide slide rod 221 is limited. At this time, the two sliding push plates 22 are only allowed to slide towards each other, thus always pressing against the outer surface of the test tube.

[0044] Reference Figure 5 As shown, this is the drive end 3 used to drive the limiting frame 20 to slide within the storage box 1. Specifically, the drive end 3 includes a synchronous pulley 30 and a synchronous belt 31. At least two synchronous pulleys 30 are symmetrically arranged on the mounting support plate 11, and the synchronous belt 31 is connected between the two synchronous pulleys 30. The synchronous belt 31 is connected to all the limiting frames 20 for limiting. In use, the synchronous pulleys 30 are driven to rotate, which drives the synchronous belt 31 and the remaining synchronous pulleys 30 to rotate synchronously. The synchronous belt 31 rotates, which drives all the limiting frames 20 connected to it and the test tubes limited on the limiting frames 20 to move, thereby achieving the sliding adjustment of the position of the test tubes in the storage box 1, which facilitates the staff to import the collected samples into the empty test tubes.

[0045] Reference Figure 5 and Figure 6 As shown, a drive rod 32 that penetrates downward through the mounting support plate 11 is connected to the middle of one of the synchronous pulleys 30. A supporting slide plate 33 is sleeved on the mounting drive rod 32. The end of the supporting slide plate 33 near the limiting frame 20 is set as an inclined section. The inclined section is used in conjunction with the extension rod 223 so that the opposing extension rod 223 can slide along its inclined surface.

[0046] In use, the drive rod 32 is rotated, which in turn drives the connected synchronous pulley 30 to rotate, thereby driving the synchronous belt 31 and the limiting frame 20 to rotate and shift. When any one of the limiting frames 20 is rotated to correspond to the position of the supporting slide plate 33, the limiting frame 20 drives the sliding push plate 22 and the extension rod 223 to rotate until they are in contact with the inclined surface on the supporting slide plate 33. The supporting slide plate 33 restricts the sliding of the extension rod 223, thereby pressing the sliding side plate 220 against the test tube. In this embodiment, the drive rod 32 is driven by a drive motor. Specifically, the lower end of the drive rod 32 is connected to a drive motor installed between the bottom wall of the storage box 1 and the mounting support plate 11. The drive motor is installed in the storage box 1 through a motor mount. In actual use, the output shaft of the drive motor drives the drive rod 32 to rotate synchronously.

[0047] Reference Figure 6 and Figure 7As shown, the drive lever 32 includes a rotating bar 320 passing through the middle of the synchronous pulley 30. The rotating bar 320 passes downward through the support plate 11 and the guide frame plate 35. A sliding bar 321 is inserted on the rotating bar 320. The sliding bar 321 and the rotating bar 320 are connected by several circumferentially distributed anti-rotation blocks 322. The anti-rotation blocks 322 are connected to the sliding bar 321. The synchronous pulley 30 has a locking groove adapted to the anti-rotation blocks 322. After the sliding bar and the anti-rotation blocks 322 are inserted into the synchronous pulley 30, the synchronous pulley 30 is driven to rotate. The supporting slide plate 33 is sleeved on the sliding bar 321. In use, by moving the rotating bar 320 vertically, the rotating bar 320 moves and drives the connected anti-rotation block 322 to be inserted into the engagement groove, so that the anti-rotation block 322 is simultaneously inserted on the synchronous pulley 30 and the rotating bar 320. Thus, when the rotating bar 320 is driven to rotate, the rotating bar 320 rotates and drives the anti-rotation block 322 to rotate. The rotation of the anti-rotation block 322 drives the sliding bar 321 and the synchronous pulley 30 to rotate, thereby driving the synchronous belt 31 to rotate, so as to achieve the effect of moving and adjusting the test tubes on the limiting frame 20 within the storage box 1.

[0048] Reference Figures 8 to 10 As shown, a limiting sleeve 34, concentric with the sliding bar 321 and with its opening facing downward, is provided on the partition plate 10. A spiral groove 340 is provided inside the limiting sleeve 34. The spiral groove 340 includes at least two vertical grooves and a spiral groove that are spaced apart and staggered. The two ends of the vertical grooves and the spiral groove are connected alternately. A synchronous protrusion 341 connected to the sliding bar 321 is slidably inserted inside the spiral groove 340. An adjusting spring 342 is provided between the upper ends of the limiting sleeve 34 and the sliding bar 321. The adjusting spring 342 is rotatably connected to the sliding bar 321.

[0049] In use, the sliding bar 321 drives the connected stop block to be inserted into the synchronous pulley 30 and the rotating bar 320. At this time, the rotating bar 320 is driven to rotate, which drives the anti-rotation block 322, the sliding bar 321 and the synchronous pulley 30 to rotate. The rotation of the synchronous pulley 30 drives the synchronous belt 31 to rotate, thereby driving all the limiting frames 20 and the test tubes limited on the limiting frames 20 to adjust their positions in the storage box 1. The rotation of the sliding bar 321 drives the synchronous convex rod 3... 41 rotates around the sliding bar 321 as an axis, and the synchronous convex rod 341 rotates and slides along the spiral groove 340. While driving the sliding bar 321 to rotate, it also slides in the vertical direction. The upward movement of the sliding bar 321 causes the adjusting spring 342 to be compressed by force. When the synchronous convex rod 341 slides to the vertical groove, it drives the sliding bar 321 to quickly return to its original position. The upward movement of the sliding bar 321 also causes the moving stop block of the synchronous belt 31 to move upward and disengage from the synchronous belt pulley 30 and the rotating bar 320, thereby limiting the continued rotation of the limit frame 20.

[0050] Reference Figures 5 to 10 As shown, a guide frame plate 35 is provided on the mounting support plate 11, located below all the limit frames 20. The guide frame plate 35 has an upward inclined surface on the side near the opening on the partition plate 10, which is used to guide the sliding of the limit frame 20 in the storage box 1. An anti-rotation frame 36 is provided on the limit sleeve to limit the support slide plate 33. The anti-rotation frame 36 includes a vertical guide rod 360 provided on the limit sleeve 34. The outer sides of the vertical guide rod 360 and the sliding bar 321 are jointly fitted with a linkage disc 361. The vertical guide rod 360 slides through the linkage disc 361. The sliding bar 321 is rotatably connected to the linkage disc 361. The lower end of the linkage disc 361 is symmetrically provided with an extension protrusion 362. Limit grooves 363 are symmetrically opened on the support slide plate 33. A flexible arc strip is provided in the limit groove 363.

[0051] It should be noted that, in order to facilitate the protrusion of the test tube located between the mounting support plate 11 and the partition plate 10 from the opening on the partition plate 10 so that staff can collect HIV test samples on site, the lower horizontal section of the limiting frame 20 includes a snap-fit ​​block connected to the horizontal section, and a limiting sleeve that is slidably sleeved on the outer side of the snap-fit ​​block to limit the connected snap-fit ​​block. The end of the limiting sleeve away from the connected snap-fit ​​block is connected to the synchronous belt 31. The limiting sleeve is sleeved on the snap-fit ​​block, allowing the snap-fit ​​block that is limited by it to slide in the vertical direction.

[0052] In use, when the limiting frame 20 is moved to the position corresponding to the opening on the partition plate 10 by the synchronous belt 31, the limiting frame 20 slides upward a certain distance guided by the inclined surface of the guide frame plate 35. The movement of the limiting frame 20 causes the connected snap-fit ​​block to move upward, so that the snap-fit ​​block moves upward and disengages from the limiting sleeve and pushes the supporting slide plate 33 on the sliding bar 321 upward. After the supporting slide plate 33 moves upward, the extension protrusion 362 of the anti-rotation frame 36 is inserted into the limiting groove 363 on the supporting slide plate 33. After the lower end of the extension protrusion 362 contacts the arc strip in the limiting groove 363, the arc strip is squeezed and deformed as the extension protrusion 362 moves downward. After the lower end of the extension protrusion 362 is fully inserted into the limiting groove 363, the arc strip recovers its deformation and abuts against the outer surface of the extension protrusion 362 to limit the extension protrusion 362.

[0053] At this time, the sliding bar 321 moves upward, causing the linkage disc 361, the extension protrusion 362, the arc strip, and the supporting slide plate 33 to move upward as a whole. This causes the inclined section on the supporting slide bar to re-abut against the extension rod 223, which in turn drives the rotating bar 320 to rotate. The sliding bar 321 continues to move upward under the guidance of the spiral groove 340, and drives the supporting slide plate 33 to move upward. The upward movement of the supporting slide plate 33, through the inclined surface set on it, drives the extension rod 223 to penetrate into the connected sliding push plate 22 in a direction away from the sliding bar 321. This causes the two sliding side plates 220 in the sliding push plate 22 to be limited and pressed against the outer side of the test tube. After the supporting slide plate 33 moves upward and abuts against the sliding push plate 22, it pushes the sliding push plate 22 and the test tube confined in the sliding push plate 22 to move upward and protrude a section from the opening on the partition plate 10, so as to facilitate the staff to pick up and import the collected sample into the test tube.

[0054] Furthermore, referring to Figure 5As shown, the supporting slide plate 33 is equipped with an upward-extending active rod 37 that slides through the partition plate 10. In use, the upward movement of the supporting slide plate 33 causes the sliding push plate 22 and the test tube, which it is in contact with, to move upward, simultaneously causing the active rod 37 to move upward. After the staff has finished introducing the collected sample into the test tube, pressing the active rod 37 downwards removes the supporting slide plate 33 from its contact with the sliding push plate 22. The sliding push plate 22 then causes the test tube, which was previously confined by it, to move downwards into the storage box 1 for storage. After the test tube moves to the lower side of the partition plate 10, pressing the active rod 37 downwards causes the active rod 37 to move downwards, causing the supporting slide plate 33 to move upwards. As the slide continues to move downwards, the supporting slide plate 33 moves downwards, causing the extension protrusion 362, the linkage disc 361, and the sliding push rod to move downwards. The linkage disc 361 moves downwards and slides along the outer side of the vertical guide rod 360. After the linkage disc 361 contacts the lowest end of the vertical guide rod 360, it is limited by the vertical guide rod 360 and stops moving downwards. At this time, as the active rod 37 and the supporting slide plate 33 continue to move downwards, the arc strip on the supporting slide plate 33 disengages from the extension protrusion 362, thereby causing the extension protrusion 362 to disengage from the supporting slide plate 33.

[0055] The sliding bar 321 moves down, causing the connected stop block to be re-inserted onto the synchronous pulley 30 and the rotating bar 320. At this time, after the rotating bar 320 is driven to rotate, the stop block, the sliding bar 321 and the synchronous pulley 30 continue to rotate. The rotation of the synchronous pulley 30 drives the synchronous belt 31 and another synchronous pulley 30 to rotate. After the synchronous belt 31 rotates, it drives all the limiting frames 20 to continue to shift and adjust within the storage box 1, so that the test tube that has just been introduced into the collection slides to another position, and drives the other limiting frame 20 and the test tube adjacent to it to move to the position corresponding to the opening on the partition plate 10, so as to carry out the next test tube collection.

[0056] During the work, the first step is to place several test tubes in the storage box 1 and limit each test tube with the limiting frame 20. Then, the staff will transport the storage box 1 containing the test tubes to the collection site.

[0057] The second step is to open the storage box 1 and drive the synchronous belt 31 to rotate so that the test tube on one of the limiting frames 20 rotates to the position corresponding to the opening on the partition plate 10. At the same time, drive the sliding bar 321 to rotate and stop the synchronous belt 31 from rotating. During the rotation of the sliding bar 321, the test tube that is limited on the limiting frame 20 is pushed up and protrudes a section from the opening on the partition plate 10.

[0058] In the third step, after one of the test tubes protrudes, the staff will guide the collected sample into the test tube and drive the limiting frame 20 to move the test tube back down between the mounting support plate 11 and the partition plate 10. Then, the synchronous belt 31 will continue to rotate to collect the sample from the next test tube. This process will be repeated until all the test tubes in the storage box 1 have been collected.

[0059] The fourth step involves the staff transferring the storage box 1 containing the test tubes after the on-site sampling is completed, thus completing the transfer of the sampled test tubes.

[0060] Fifth step: After being transported to the laboratory, the staff opens storage box 1 and removes the partition plate 10 from storage box 1, and then takes out the test tubes that are placed inside storage box 1.
