Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a portable nucleic acid extraction device. Background Technology

[0002] Nucleic acid extraction is a very important technique in life science research, biotechnology applications, and gene diagnosis. Early nucleic acid extraction was based on the principle of phenol-chloroform extraction to remove impurities and ethanol precipitation of nucleic acid. The substance detected by nucleic acid testing is the nucleic acid of the virus. Nucleic acid testing is used to find whether the nucleic acid of the foreign invading virus is present in human respiratory specimens, blood, or feces to determine whether the virus is present in the patient's body. After the virus infects the human body, it will first multiply in the respiratory system. Therefore, the presence of viral nucleic acid in sputum or nasopharyngeal swabs can determine whether the human body is infected with the virus.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0004] In existing extraction devices, the test tubes are still exposed after being clamped, making them susceptible to bumps and making them inconvenient to carry. Furthermore, existing extraction devices lack a structure to secure the test tubes during transfer, which can easily cause them to break due to jolting and lead to contamination.

[0005] Therefore, those skilled in the art have provided a portable nucleic acid extraction device to address the problems mentioned in the background section. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable nucleic acid extraction device that can store the collection tubes to make them easier to carry and prevent the tubes from being damaged during transfer.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A portable nucleic acid extraction device includes a storage box, inside which a test tube rack is provided. The test tube rack includes a first plate, a second plate, and a third plate. A second screw is rotatably provided at the center of both sides of the lower end face of the first plate. A locking block is fixedly provided at the center of both sides of the lower end face of the third plate. A groove is opened at the center of the two locking blocks on the opposite side.

[0009] Both sides of the outer wall of the storage box are slidably embedded with sliders. Each slider has a fixing mechanism inside. Each fixing mechanism includes an insert. A pull rod is fixedly installed at the center of one side of each insert. A fixing plate is fixedly installed on the opposite side of the two sliders. The upper surface of the fixing plate has slots on both sides. A screw is rotatably embedded at the center of the lower surface of the outer wall of the storage box.

[0010] Furthermore, multiple silicone frames are embedded in the upper surface of the first plate layer, and multiple bottom grooves are opened on the upper surface of the second plate layer. The two No. 2 screws are threaded through the center of both sides of the upper surface of the second plate layer and are respectively rotatably set at the center of both sides of the upper surface of the third plate layer.

[0011] Furthermore, springs are movably sleeved on the outer walls of both pull rods, and the two ends of the two springs are respectively fixedly connected to one side of the inner walls of the two inserts and the two sliders.

[0012] Furthermore, the two card blocks are respectively snapped into the two card slots, and the two inserts are respectively embedded in the two insert slots.

[0013] Furthermore, the lower ends of both sides of the outer wall of the storage box are provided with sliding grooves, and the two sliders are respectively embedded in the two sliding grooves. The first screw thread passes through the center of the lower end face of the fixing plate and slides through the third plate layer.

[0014] Furthermore, a lid is hinged to the rear end of the upper surface of the storage box, and a silicone pad is fixedly installed at the center of the lower surface of the lid.

[0015] Furthermore, handles are rotatably provided on both the upper ends of the front and rear end faces of the storage box.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a portable nucleic acid extraction device, in which a sampling tube is inserted through the first plate layer along the silicone frame so that the bottom end of the sampling tube is embedded in the bottom groove on the second plate layer. Then, two screws are rotated at the same time to drive the second plate layer to rise and fall, so that the tube rack can hold sampling tubes of different lengths and specifications, and put them into the storage box for storage. The storage box protects the sampling tubes, making them easy to carry.

[0018] 2. The portable nucleic acid extraction device proposed in this utility model involves placing a test tube rack inside a storage box, with two locking blocks embedded in two slots respectively. At this time, the two inserts are embedded in the two slots under the action of two springs, thereby fixing the test tube rack inside the storage box. Then, the box lid is closed and the No. 1 screw is rotated to one side to move the fixing plate and the test tube rack upward until the sampling test tube contacts the silicone pad, thereby achieving the effect of fixing the position of the test tube and effectively preventing the test tube from shaking and colliding during transportation, which could cause the test tube to break.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 4 One embodiment provided by this utility model:

[0027] A portable nucleic acid extraction device includes a storage box 1. Inside the storage box 1, there is a test tube rack 12. The test tube rack 12 includes a first plate layer 1201, a second plate layer 1203, and a third plate layer 1204. A second screw 1202 is rotatably installed at the center of both sides of the lower end face of the first plate layer 1201. A locking block 7 is fixedly installed at the center of both sides of the lower end face of the third plate layer 1204. A groove 8 is opened at the center of the two locking blocks 7 on the side away from each other.

[0028] The storage box 1 has sliders 4 slidably embedded on both sides of its outer wall. Each slider 4 has a fixing mechanism 13 inside. Each fixing mechanism 13 includes a block 1303. A pull rod 1301 is fixedly installed at the center of one side of each block 1303. A fixing plate 5 is fixedly installed on the opposite side of the two sliders 4. The upper surface of the fixing plate 5 has slots 6 on both sides. A screw 14 is rotatably embedded at the center of the lower surface of the outer wall of the storage box 1.

[0029] Specifically, the test tube rack 12 is used to place and fix the sampling test tubes, and the storage box 1 is used to store the test tube rack 12 to prevent it from being broken by collision with hard objects during transportation. The design of the slider 4 and the locking block 7 can achieve the fixing effect between the test tube rack 12 and the fixing plate 5. The height of the fixing plate 5 can be adjusted by the screw 14, which can effectively prevent the test tube rack 12 from shaking and being bumped during transportation.

[0030] Reference Figure 2 , Figure 3 Multiple silicone frames 10 are embedded in the upper surface of the first plate 1201, and multiple bottom grooves 9 are opened on the upper surface of the second plate 1203. Two No. 2 screws 1202 are threaded through the center of both sides of the upper surface of the second plate 1203 and are respectively rotatably set at the center of both sides of the upper surface of the third plate 1204.

[0031] Specifically, the design of the silicone frame 10 and the bottom groove 9 can clamp and fix the sampling tube, and the distance between the first plate layer 1201 and the second plate layer 1203 can be controlled by the second screw 1202.

[0032] Reference Figure 4 Both pull rods 1301 have springs 1302 movably sleeved on their outer walls. The two ends of the two springs 1302 are fixedly connected to one side of the inner wall of the two inserts 1303 and the two sliders 4, respectively.

[0033] Specifically, the spring 1302 can move the insert 1303 to one side under the action of the spring force of the spring 1302 under normal conditions.

[0034] Reference Figure 2 , Figure 3Two card blocks 7 are respectively snapped into the two card slots 6, and two insert blocks 1303 are respectively embedded in the two insert slots 8.

[0035] Specifically, it can achieve a locking effect between the third plate 1204 and the fixing plate 5, thereby fixing the test tube rack 12 inside the storage box 1.

[0036] Reference Figure 1 , Figure 3 The storage box 1 has grooves 3 through the lower ends of both sides of its outer wall. Two sliders 4 are respectively embedded in the two grooves 3. The first screw 14 is threaded through the center of the lower end of the fixing plate 5 and slides through the third plate layer 1204.

[0037] Specifically, by sliding the slider 4 inside the groove 3, the first screw 14 can drive the third plate layer 1204 to move up or down during rotation.

[0038] Reference Figure 3 The storage box 1 has a lid 2 hinged to the rear end of its upper surface, and a silicone pad 11 is fixedly installed at the center of the lower surface of the lid 2.

[0039] Specifically, the silicone pad 11 can hold the top of the sampling tube in place, preventing the sampling tube from shaking and breaking.

[0040] Reference Figure 1 , Figure 3 The storage box 1 has handles on both the upper sides of the front and rear ends.

[0041] Specifically, the handle facilitates the transfer of the storage box 1 and the sampling tubes inside.

[0042] Working principle: After the test tubes are sampled, they are placed inside the silicone rack 10, with the bottom of the test tubes embedded in the bottom groove 9. Then, the height of the second plate 1203 is adjusted by rotating the two screws 1202 simultaneously, so that the top of the multiple sampling test tubes slightly protrudes from the upper surface of the first plate 1201. The adjusted test tube rack 12 is then placed inside the storage box 1, and the two locking blocks 7 are respectively embedded in the two locking slots 6. At this time, the two inserts 1303 are respectively embedded in the two inserts 8 under the action of the two springs 1302, thereby connecting and fixing the third plate 1204 and the fixing plate 5. Then, the box cover 2 is closed, and the screw 14 is rotated to make the fixing plate 5 move the test tube rack 12 upward, so that the top of the multiple sampling test tubes are in contact with the silicone pad 11, so as to facilitate the transport and carrying of the test tubes and prevent the test tubes from colliding with hard objects during the transport process and breaking.
