Description

Technical Field

[0001] The present invention relates to the field of biological detection technology, and in particular to a coronavirus PCR detection kit and a method for using the same. Background Art

[0002] When faced with a large number of test samples, in order to reduce the difficulty of testing and shorten the testing process, single-tube mixed testing is generally adopted. After the sample collection is completed in multiple groups of single tubes, they are placed in the test kit for storage and then sent to the laboratory for PCR testing.

On the other hand, when the sealing cover is fully opened, the base and the support plate move upward along the length direction of the sliding guide part and protrude from the storage box, which makes it more convenient for the inspector to take the test tubes on the base and the support plate.

[0036] By setting up an oscillation component, the base and the support plate drive the test tube to move upward, causing the test tube to oscillate. Therefore, before the test tube is taken out, the test tube can be oscillated to a certain extent, thereby avoiding the precipitation of the liquid in the test tube and improving the uniformity of the liquid in the test tube before detection.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0049] In an embodiment of the present invention, a coronavirus PCR detection kit includes: a storage box 1, a loading structure, a lifting assembly, and an oscillation assembly, which is used to store test tubes filled with a predetermined number of throat swabs. Before taking out the test tubes, the test tubes can be shaken to a certain extent to avoid precipitation of the liquid in the test tubes and improve the uniformity of the liquid in the test tubes before testing.

[0050] See also Figure 1 、 Figure 2 、 Figure 4 , specifically as follows: a sealing cover plate 2 is rotatably mounted on the storage box body 1;

[0051] The loading structure is arranged in the storage box 1, and multiple sets of coronavirus PCR detection reagents can be inserted into the loading structure;

[0052] The loading structure includes a base 3 disposed in the storage box 1 and a support plate 4 disposed parallel to the base 3, wherein the support plate 4 is provided with a plurality of through holes 6, and the base 3 is provided with a concave base 5 corresponding to the through holes 6;

[0053] The base 3 is connected to the oscillating component.

[0054] During use, a test tube filled with a predetermined number of pharyngeal swabs can be inserted into the through hole 6 on the support plate 4 until the bottom of the test tube abuts against the concave base 5. At this time, the interior of the test tube is embedded in the concave base 5, and the upper part of the test tube is supported by the through hole 6 to prevent the test tube from tilting and colliding with adjacent test tubes during the process of moving the base 3 and the support plate 4, thereby preventing the test tube from being damaged. This means that when the test tube is placed in the through hole 6, the test tube is kept in a vertical upward position.

[0055] Through the above arrangement, the multiple test tubes placed between the support plate 4 and the base 3 can be kept in a vertical and parallel state. On the one hand, it can prevent a test tube from tilting and colliding with an adjacent test tube during transportation, causing damage to the test tube. At the same time, the test tube is kept in a vertical upward state, thereby reducing the risk of internal liquid spilling during transportation.

[0056] See also Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 The lifting assembly is arranged in the storage box 1 and connects the loading structure and the sealing cover plate 2. The lifting assembly includes a gap driving structure and a yaw structure. The gap driving structure can drive the loading structure to move toward the top of the storage box 1 through the yaw structure after the sealing cover plate 2 rotates a predetermined angle relative to the storage box 1;

[0057] The gap driving structure includes a turntable 15 rotatably mounted in the storage box 1, a connecting rod 16 rotatably mounted on the turntable 15, and an end of the connecting rod 16 away from the turntable 15 is rotatably connected to the sealing cover plate 2;

[0058] The connecting rod 16 is located above the rotation center of the turntable 15;

[0059] The gap drive structure also includes a clutch kit connected to the rotating shaft of the rotary disk 15, and the clutch kit includes an active disk 18 and a driven disk 20 rotatably mounted on the storage box 1, the active disk 18 and the driven disk 20 are coaxial and parallel, and a second cam 19 is fixed at an eccentric position of the active disk 18, and the second cam 19 can slide in an arc-shaped groove 21 formed on the driven disk 20;

[0060] The driving disc 18 is connected to the rotating disc 15 via a belt 17, and the driven disc 20 is connected to the yaw structure. The yaw structure includes a yaw rod 22 fixedly connected to the driven disc 20, and a pulley 23 is rotatably mounted on one end of the yaw rod 22 away from the driven disc 20;

[0061] The deflection structure further includes a horizontal guide member 24 fixedly connected to the base 3. The horizontal guide member 24 is provided with a horizontal slide groove 25 along its length, and the pulley 23 can slide in the horizontal slide groove 25.

[0062] The base 3 is connected to the storage box 1 via a stretching assembly, which includes a placement mounting frame 26 fixed to the storage box 1, a fitting block 29 slidably mounted in the placement mounting frame 26, a pulling rod 28 rotatably mounted on the fitting block 29, and an end of the pulling rod 28 away from the fitting block 29 is rotatably connected to the base 3;

[0063] The placement and mounting frame 26 is further provided with a second cylindrical spring 27, one end of the second cylindrical spring 27 is connected to the interlocking block 29, and the other end is connected to the inner wall of the placement and mounting frame 26;

[0064] The base 3 and the support plate 4 are connected by a connecting plate, and a horizontal shaft 8 is slidably installed on the connecting plate. Two sliders 11 are symmetrically provided at both ends of the horizontal shaft 8. The sliders 11 can slide in a sliding guide part 12 provided on the inner wall of the storage box 1.

[0065] In the initial state, the base 3 and the support plate 4 are inside the storage box 1, and the sealing cover 2 is in a closed state. When the sealing cover 2 is opened, the sealing cover 2 will pull the turntable 15 to rotate through the connecting rod 16. When the turntable 15 rotates, the rotating shaft of the turntable 15 will drive the active disk 18 to rotate through the belt 17, and make the second convex shaft 19 set on the active disk 18 do a circular motion. Specifically, in the initial stage of the circular motion of the second convex shaft 19, the second convex shaft 19 will be in the arc concave The base 3 and the support plate 4 are in a stationary state due to the presence of the No. 2 columnar spring 27, the engaging block 29 and the pulling rod 28. That is, the sealing cover 2 is in a stationary state before it is opened. At this time, the inspector can check the test tubes between the base 3 and the support plate 4 to check whether there are any damaged test tubes or liquid overflowing during transportation, so as to avoid the spread of pathogens in the test tubes due to damage or liquid overflowing in the test tubes, which may cause infection to the inspectors.

[0066] When the No. 2 cam 19 rotates to the end of the arc-shaped groove 21, the No. 2 cam 19 drives the driven disk 20 to rotate by abutting against the arc-shaped groove 21. When the driven disk 20 rotates, it can drive the deflection plate rod 2 to deflect upward, and make the pulley 23 slide in the horizontal slide groove 25 in the horizontal guide member 24, thereby driving the base 3 and the support plate 4 to move upward along the length direction of the sliding guide part 12 and protrude from the storage box 1. At this time, it is more convenient for the inspection personnel to pick up the test tubes on the base 3 and the support plate 4.

[0067] Through the above arrangement, on the one hand, in the stage before the sealing cover 2 is opened, the base 3 and the support plate 4 are in a stationary state. At this time, the inspector can check the test tubes between the base 3 and the support plate 4 to check whether there are any damaged test tubes or liquid overflowing during transportation, so as to avoid the spread of pathogens in the test tubes due to damage or overflow of liquid in the test tubes, which may cause the inspectors to be infected. On the other hand, when the sealing cover 2 is fully opened, the base 3 and the support plate 4 move upward along the length direction of the sliding guide part 12 and protrude from the storage box 1. At this time, it is more convenient for the inspector to pick up the test tubes on the base 3 and the support plate 4.

[0068] See also Figure 5 The oscillating component connects the storage box 1 and the loading structure, and the oscillating component can drive the loading structure to vibrate when the loading structure moves;

[0069] The oscillation assembly includes a first convex shaft 7 fixedly connected to the connecting plate and a vertical plate 13 fixedly mounted on the inner wall of the storage box 1. A convex portion 14 is provided on one side of the vertical plate 13, and the first convex shaft 7 can slide on the convex portion 14.

[0070] The oscillation assembly further includes a reset kit provided on the transverse shaft 8, the reset kit including a No. 1 cylindrical spring 10 sleeved on the transverse shaft 8, one end of the No. 1 cylindrical spring 10 being connected to the connecting plate, and the other end being connected to one of the sliders 11;

[0071] The reset kit further includes a limiting ring 9 arranged on the transverse shaft 8 and adapted to the connecting plate.

[0072] When the base 3 and the support plate 4 rise, the No. 1 cam 7 will be driven to rise. In the initial state, the No. 1 column spring 10 has a pushing force on the connecting plate, and the connecting plate is in contact with the limit ring 9, so that the relative position of the base 3 and the support plate 4 on the horizontal axis 8 is stable. In this state, the No. 1 cam 7 is located between the recessed parts between the two adjacent protrusions 14, and as the No. 1 cam 7 rises, the No. 1 cam 7 will move between the protrusions 14 and the recessed parts in turn, driving the base 3 and the support plate 4 to reciprocate along the length direction of the horizontal axis 8, thereby causing the test tube placed on the base 3 and the support plate 4 to reciprocate, and the frequency of this reciprocating motion is high, so that the test tube can be oscillated, so that before the test tube is taken out, the test tube can be oscillated to a certain extent, thereby avoiding the precipitation of the liquid in the test tube and improving the uniformity of the liquid in the test tube before detection.

[0073] Through the above arrangement, the base 3 and the support plate 4 drive the test tube to move upward, which can cause the test tube to vibrate. Therefore, before the test tube is taken out, the test tube can be vibrated to a certain extent, thereby avoiding the precipitation of the liquid in the test tube and improving the uniformity of the liquid in the test tube before detection.

[0074] As an embodiment of the present invention, a method for using the coronavirus PCR detection kit is also proposed, comprising the following steps:

[0075] Step 1: Break off the end of the sampled throat swab and place it in the test tube. When the test tube is full of the designed number of throat swabs, close the upper cover of the test tube and insert the test tube into the loading structure;

[0076] Step 2: insert the test tubes into the loading structure in sequence until the loading structure is full of test tubes;

[0077] Step 3: Close the sealing cover 2 and transport it to the testing laboratory;

[0078] Step 4: When the storage box 1 filled with test tubes to be inspected is transported to the laboratory, the sealing cover 2 is opened. During the first period of time when the sealing cover 2 is opened, the loading structure is in a stationary state. At this time, the inspection personnel can inspect the appearance of the test tubes on the loading structure to check whether the test tubes have been damaged during transportation;

[0079] Step 5: Continue to open the sealing cover 2. At this time, the loading structure will move toward the top of the storage box 1 under the action of the jacking assembly, and under the action of the oscillation assembly, the loading structure will drive the test tube to oscillate when it rises;

[0080] Step 6: Test the throat swab mixture in the test tube.

[0081] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
