A storage device for nucleic acid detection samples

Abstract

The application is suitable for the field of nucleic acid detection, and provides a storage device for nucleic acid detection samples, a storage box, and a plurality of first placing racks for containing sample test tubes are arranged in the storage box. The application has novel design. When in use, a recognition probe installed recognizes the test tube of the throat swab being stored. Medical staff members put the detected throat swab into the partition rack through the round hole on the partition rack. An infrared sensor recognizes the throat swab entering the partition rack. Because the throat swab is thin, the difference between the finger and other objects is small. Therefore, the electric telescopic rod on one side operates. The movable end of the electric telescopic rod pushes the connecting block on one side to move. The moving connecting block drives the cutting plate fixed thereto to move. Because the cutting plate slides on the slide rods on both sides, the cutting plate can only move in a horizontal straight line. The throat swab in the test tube is cut off through the movement of the cutting plate. The efficiency of nucleic acid detection is faster through the partition assembly.

Description

Technical Field

[0001] This invention relates to the field of nucleic acid testing, specifically to a storage device for nucleic acid testing samples. Background Technology

[0002] Nucleic acid testing is a common testing method during the pandemic. It can determine whether there is a viral infection in a short time. Nucleic acid testing usually involves taking a sample from the throat or nose with a cotton swab and then testing to get the result. A nucleic acid test tube can hold one sample or several samples.

[0003] When screening for infection in large populations, nucleic acid testing uses a pooled sampling method, placing samples from 5 or 10 people into a collection tube, and then testing with reagents. The test involves swabbing both sides of the pharyngeal tonsils and the posterior pharyngeal wall with a cotton swab, placing the swab into a test tube containing virus preservation solution, breaking off the end of the swab, and tightening the screw cap. However, nucleic acid testing often requires testing large populations, and the long testing time necessitates operators constantly breaking off the ends of the swabs, leading to an increase in the workload of testing personnel. Summary of the Invention

[0004] The purpose of this invention is to provide a storage device for nucleic acid detection samples to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The storage box contains multiple first placement racks for holding sample tubes. One first placement rack is fixedly installed inside the storage box, and the other first placement rack is connected to a support component installed inside the storage box. The support component separates the two first placement racks from each other. The storage box is equipped with a locking component connected to the support component. The locking component locks the first placement rack after it is raised by the support component, preventing the first placement rack from sliding down.

[0008] A pusher is installed on one side of the storage box, which pushes ice into the storage box to cool the sample tubes placed on the first placement rack. A separator rack is fixedly installed inside the storage box, and a separation component is installed inside the separator rack to separate the nucleic acid test pharyngeal swabs.

[0009] As a further aspect of the present invention: the support assembly includes a plurality of support columns fixedly installed on a first placement frame, and another first placement frame has a circular hole for the support columns to slide through. A support plate is fixedly installed inside the storage box, and a plurality of telescopic rods for supporting the first placement frame are fixedly installed on the support plate. The movable ends of the telescopic rods are fixedly installed with the first placement frame.

[0010] As a further embodiment of the present invention: the locking component includes a plurality of circular holes formed on one of the support columns, a prism fixedly installed inside the support column, a sliding plate that slides on the prism below the circular holes, a first compression spring sleeved on the prism and the inner wall of the support column abutting between the sliding plate and the prism, an arc-shaped locking block fixedly installed with the sliding plate is placed in one of the circular holes, and a locking groove for the arc-shaped locking block to be engaged is formed on the first placement frame.

[0011] As a further embodiment of the present invention: a first cylinder is fixedly installed on one side of the storage box, a sliding plate is slidably connected inside the first cylinder, a pressing column extending out of the first cylinder is fixedly installed on one side of the sliding plate, a pressing plate is fixedly installed at the end of the pressing column away from the sliding plate, a circular hole is opened on the first cylinder for the pressing column to pass through, a squeezing column extending into the storage box is fixedly installed on the side of the sliding plate away from the pressing column, the end of the squeezing column away from the sliding plate cooperates with the sliding plate, and a circular hole is opened on the storage box for the squeezing column to pass through, and a second compression spring sleeved on the squeezing column is abutted between the sliding plate and the storage box.

[0012] As a further embodiment of the present invention: the pusher includes a circular hole opened on the storage box, a push rod that is slidably connected in the circular hole and fixedly installed with the pusher plate, and the pusher plate slides on the support plate.

[0013] As a further embodiment of the present invention: the segmentation component includes an identification probe fixedly installed on one side of the segmentation frame, the segmentation frame having a circular hole for a nucleic acid testing pharyngeal swab to pass through, a cutting plate sliding inside the segmentation frame below the circular hole, multiple sliding rods fixedly installed inside the segmentation frame, sliding blocks fixedly installed on the sliding rods and the cutting plate, an electric telescopic rod fixedly installed on the segmentation frame, a connecting block fixedly installed at the movable end of the electric telescopic rod, the connecting block being fixedly installed on the cutting plate, and an infrared sensor fixedly installed on the segmentation frame.

[0014] As a further embodiment of the present invention: a second cylinder is fixedly installed inside the partition frame, a clamping block is provided on one side of the second cylinder, a push column extending into the second cylinder is fixedly installed on the clamping block, a push plate that slides inside the second cylinder is fixedly installed at the end of the push column away from the clamping block, a third compression spring abuts against the inner wall of the partition frame, and a trigger button that cooperates with the push plate is fixedly installed on the partition frame.

[0015] As a further embodiment of the present invention: a top cover is placed on the storage box, a hinge seat is installed between the top cover and the storage box, rubber blocks distributed in a circle are fixedly installed in the placement holes on the first placement frame, a rectangular window communicating with the partition frame is opened on the storage box, a dustproof plate is slidably connected in the rectangular window, and a handle is fixedly installed on the dustproof plate.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention features a novel design. During use, the installed identification probe identifies the test tube containing the throat swab. Medical personnel insert the tested throat swab through the round hole on the separator rack. An infrared sensor identifies the throat swab entering the separator rack. Because throat swabs are thin and distinguishable from fingers and other objects, an electric telescopic rod on one side rotates. The movable end of the electric telescopic rod pushes a connecting block on one side to move. The moving connecting block drives a cutting plate fixed to it to move. Because the cutting plate slides on sliding rods on both sides, it can only move in a horizontal straight line. The movement of the cutting plate cuts the throat swab placed in the test tube. Simultaneously, the electric telescopic rod is connected to a control panel, which controls the number of times the electric telescopic rod rotates. Through the cooperation of the electric telescopic rod and the infrared sensor, only a certain amount of throat swabs can be stored in a single sample test tube, preventing the storage of more swabs. The separator component makes nucleic acid testing more efficient. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0029] Please see Figures 1-9 In this embodiment of the invention, a storage device for nucleic acid detection samples includes:

[0030] The storage box 1 is provided with a plurality of first placement racks 11 for holding sample test tubes. One of the first placement racks 11 is fixedly installed in the storage box 1, and the other first placement rack 11 is connected to a support assembly installed in the storage box 1. The two first placement racks 11 are separated from each other by the support assembly.

[0031] Please see Figure 3 , Figure 4The support assembly includes a plurality of support columns 13 fixedly installed on the first placement frame 11. Another circular hole is provided on the first placement frame 11 for the support column 13 to slide through. A support plate 16 is fixedly installed inside the storage box 1. A plurality of telescopic rods 15 for supporting the first placement frame 11 are fixedly installed on the support plate 16. The movable end of the telescopic rod 15 is fixedly installed with the first placement frame 11.

[0032] When it is necessary to place the sample tube on the lower first placement rack 11, pull the first placement rack 11 upward. The upward movement of the first placement rack 11 causes the movable end of the telescopic rod 15 to move upward, and at the same time, it causes the multiple support columns 13 on the other side to move upward. The upward movement of the support columns 13 and the movable end of the telescopic rod 15 separates the two first placement racks 11 from each other, making it easier to place the sample tube on the lower first placement rack 11. Of course, the support columns 13 and the telescopic rod 15 make the movement of the upper first placement rack 11 more stable, and make it only able to move in a straight line up and down.

[0033] Preferably, an electric telescopic rod is fixedly installed on the support plate 16, and the movable end of the electric telescopic rod is fixedly installed with the first placement frame 11. The electric telescopic rod can automatically push the first placement frame 11 to move up and down.

[0034] The storage box 1 is equipped with a locking component connected to the support component. The locking component locks the first placement rack 11 after it is raised by the support component, so that the first placement rack 11 will not slide down.

[0035] Please see Figure 4 , Figure 5 The locking assembly includes multiple circular holes formed on one of the support columns 13. A prism 18 is fixedly installed inside the support column 13. A sliding plate 17 is provided below the circular holes and slides on the prism 18. A first compression spring 19 sleeved on the prism 18 abuts between the sliding plate 17 and the inner wall of the support column 13. An arc-shaped locking block 14 fixedly installed with the sliding plate 17 is placed in one of the circular holes. A locking groove for the arc-shaped locking block 14 to be locked on is provided on the first placement frame 11.

[0036] When the first placement frame 11 moves to its apex, it pushes the abutting arc-shaped locking block 14 to move. The moving arc-shaped locking block 14 pushes the fixed slide plate 17 to move. Because the slide plate 17 slides on the prism 18, it can only move in a reciprocating straight line. The moving slide plate 17 pushes the first compression spring 19 fixed to it to compress. The support column 13 continues to move, driving the arc-shaped locking block 14 into the locking groove. At this time, the compressed first compression spring 19 pushes the slide plate 17 and the arc-shaped locking block 14 fixed on it to press tightly against the locking groove, so that the first placement frame 11 will not easily slide down.

[0037] Preferably, an electric telescopic rod is fixedly installed inside the support column 13. The movable end of the electric telescopic rod is fixedly installed with the slide plate 17. The electric telescopic rod can automatically push the arc-shaped locking block 14 to move and control the opening and closing of the locking component.

[0038] Please see Figure 3 , Figure 4 , Figure 6 A first cylinder 2 is fixedly installed on one side of the storage box 1. A sliding plate 20 is slidably connected inside the first cylinder 2. A pressing post 12 extending outside the first cylinder 2 is fixedly installed on one side of the sliding plate 20. A pressing plate 3 is fixedly installed on the end of the pressing post 12 away from the sliding plate 20. A circular hole is opened on the first cylinder 2 for the pressing post 12 to pass through. A squeezing post 22 extending into the storage box 1 is fixedly installed on the side of the sliding plate 20 away from the pressing post 12. The end of the squeezing post 22 away from the sliding plate 20 cooperates with the sliding plate 17. A circular hole is opened on the storage box 1 for the squeezing post 22 to pass through. A second compression spring 21 sleeved on the squeezing post 22 abuts against the sliding plate 20 and the storage box 1.

[0039] When the locking assembly fixes the support column 13 to the first placement frame 11, the locked first placement frame 11 cannot move downwards and the locking assembly needs to be released. At this time, the pressing plate 3 is pressed to one side, and the moving pressing plate 3 pushes the pressing column 12 fixed on it to move. The moving pressing column 12 pushes the sliding plate 20 inside the first cylinder 2 to slide to the other side. The sliding plate 20 pushes the pressing column 22 on one side to move. The moving pressing column 22 passes through the hole and abuts against the slide plate 17, and pushes the slide plate 17 to move. The moving slide plate 17 drives the arc-shaped locking block 14 to disengage from the locking groove, so that the first placement frame 11 above can move down to its original position. At the same time as the slide plate 17 moves, it also squeezes the first compression spring 19.

[0040] A pusher is installed on one side of the storage box 1, which pushes ice blocks into the storage box 1 to cool the sample tubes placed on the first placement rack 11.

[0041] Please see Figure 3 , Figure 8 The pushing component includes a circular hole formed on the storage box 1, and a pushing rod 5 that is fixedly installed in the pushing plate 25 is slidably connected in the circular hole, and the pushing plate 25 slides on the support plate 16.

[0042] When the external temperature is high, ice blocks are poured into the storage box 1 through the holes on both sides of the divider 10. The falling ice blocks will accumulate on the support plate 16. At this time, the push rod 5 can be pushed to one side to move the push rod 5. The moving push rod 5 drives the push plate 25 to move, pushing the accumulated ice blocks into the storage box 1.

[0043] A separator 10 is fixedly installed inside the storage box 1, and a separation component for separating nucleic acid test throat swabs is installed inside the separator 10.

[0044] Please see Figure 1 , Figure 3 , Figure 8 The segmentation assembly includes an identification probe 8 fixedly installed on one side of the segmentation frame 10. The segmentation frame 10 has a circular hole for a nucleic acid detection throat swab to pass through. Below the circular hole is a cutting plate 24 that slides within the segmentation frame 10. Multiple sliding rods 29 are fixedly installed within the segmentation frame 10. Sliding blocks that are fixedly installed on the cutting plate 24 are slidably connected to the sliding rods 29. An electric telescopic rod 27 is fixedly installed on the segmentation frame 10. A connecting block 28 is fixedly installed at the movable end of the electric telescopic rod 27. The connecting block 28 is fixedly installed on the cutting plate 24. An infrared sensor 26 is fixedly installed on the segmentation frame 10.

[0045] The identification probe 8 installed on one side can identify the label on the sample tube. When in use, the identification probe 8 identifies the test tube containing the pharyngeal swab. Medical staff insert the pharyngeal swab after testing into the separator 10 through the round hole on the separator 10. The infrared sensor 26 identifies the pharyngeal swab that has entered the separator 10. Because the pharyngeal swab is thin and can be distinguished from fingers and other objects, the electric telescopic rod 27 on one side operates. The movable end of the electric telescopic rod 27 pushes the connecting block 28 on one side to move. The moving connecting block 28 drives the cutting plate 24 fixed to it to move. Because the cutting plate 24 slides on the sliding rods 29 on both sides, the cutting plate 24 can only move horizontally in a straight line. The movement of the cutting plate 24 cuts the pharyngeal swab placed in the test tube.

[0046] It should be noted that the electric telescopic rod 27 is connected to a control panel, which controls the number of times the electric telescopic rod 27 operates. Through the cooperation of the electric telescopic rod 27 and the infrared sensor 26, only a certain amount of pharyngeal swabs can be stored in a sample tube, and no more pharyngeal swabs can be stored.

[0047] Please see Figure 1 , Figure 8 , Figure 9 A second cylinder 31 is fixedly installed inside the partition frame 10. A clamping block 30 is provided on one side of the second cylinder 31. A push column 32 extending into the second cylinder 31 is fixedly installed on the clamping block 30. A push plate 33 sliding inside the second cylinder 31 is fixedly installed at the end of the push column 32 away from the clamping block 30. A third compression spring 34 abuts between the push plate 33 and the inner wall of the partition frame 10. A trigger button 35 cooperating with the push plate 33 is fixedly installed on the partition frame 10.

[0048] In use, the sample tube to be used is attached to the clamping block 30. Because the clamping block 30 is made of rubber, the sample tube will be pushed to move when it is attached to the clamping block 30. The moving clamping block 30 pushes the push column 32 fixed to it to move continuously into the second cylinder 31. The moving push column 32 pushes the push plate 33 to slide inside the second cylinder 31. When the push plate 33 moves to a certain position, it abuts against the trigger button 35, causing the trigger button 35 to switch on the identification probe 8 on one side to operate and scan the label on the sample tube. At the same time, the control panel connected to the electric telescopic rod 27 is adjusted to refresh the number of times it operates.

[0049] Please see Figure 1 , Figure 2 The storage box 1 is equipped with a top cover 4, and a hinge seat 9 is installed between the top cover 4 and the storage box 1. Rubber blocks 23 distributed in a circle are fixedly installed in the placement holes on the first placement frame 11. The storage box 1 has a rectangular window that communicates with the partition frame 10. A dustproof plate 6 is slidably connected in the rectangular window, and a handle 7 is fixedly installed on the dustproof plate 6.

[0050] The top cover 4 can be flipped over by the connecting hinge seat 9. The flipping of the top cover 4 facilitates the opening and closing of the storage device. When nucleic acid testing is required, pull the handle 7 to one side so that the dust cover 6 moves and opens the separator 10. When it is not needed, pull the handle 7 to the other side so that the handle 7 moves the dust cover 6 and closes the separator 10.
