Description

Technical Field

[0001] The invention relates to the field of rapid biological detection, and in particular to a fully sealed reagent reaction box capable of secondary injection for rapid biological detection. Background Art

[0002] Infectious diseases are diseases caused by viral infection. In order to identify the type of virus that causes the disease, it can be divided into two categories for inspection: direct detection of the virus itself and detection of antibodies produced by the human body to resist the virus. Both methods are inseparable from rapid biological detection technology. Currently, rapid biological detection technology is widely used in vaccine development and potency determination.

[0003] When using rapid biological detection technology for testing, it is necessary to collect serum samples from patients, and then add reagents to the samples to make the samples react with the reagents to facilitate the detection of relevant data. However, when performing rapid biological detection in the prior art, reagents are manually injected into test tubes containing samples. Reagents can only be injected into one test tube at a time, which has low work efficiency. In addition, when injecting reagents in the prior art, the test tube is in a non-sealed state, which can easily lead to deviations in subsequent detection structures. At the same time, the prior art only injects reagents once, which may result in insufficient injected reagents, resulting in the sample not being able to fully react. Summary of the invention

At this time, the sliding placement frame 53 will be separated from the rectangular block 69, and the cross perforated frame 610 and the device thereon will be reversed and reset one after another. Then, the large piston rod 83 and the device thereon are manually pressed downward to make the large syringe 81 pass through the rubber cover on the test tube and penetrate into the inside of the test tube. The first return spring 82 will be compressed, and then the large piston rod 83 is continuously pressed, and the second return spring 84 will be compressed, so that the reagent in the large syringe 81 is injected into the inside of the test tube containing the sample. Then, the large piston rod 83 is released, and the first return spring 82 and the second return spring 84 will be reset and drive the large piston rod 83 to reset, thereby achieving the purpose of injecting reagents into multiple test tubes at one time.

[0057] When the large gear 68 and the device thereon rotate, under the action of the overrunning clutch 95, the dial wheel 2 94 will not rotate. When the large gear 68 and the device thereon rotate in the opposite direction, the dial wheel 2 94 will drive the dial wheel 1 92 and the device thereon to rotate and make the rotating gear 93 drive the L-shaped rack 96 and the device thereon to move downward. The third return spring 97 will be compressed accordingly, so that the downward pressure rod 98 presses the large piston rod 83 to move downward, replacing the manual pressing of the large piston rod 83. Subsequently, the third return spring 97 will reset and drive the L-shaped rack 96 and the device thereon to reset, thereby achieving the effect of automatically injecting the reagent.

[0060] The small syringe 101 is also filled with reagents. Below the small syringe 101 is a test tube that has been injected once. When the lower pressure rod 98 moves downward, it will also press the small piston rod 102. Through the cooperation of the small piston rod 102 and the device thereon, the reagent inside the small syringe 101 is added to the test tube that has been injected once to replenish the reagent, thereby ensuring sufficient reaction of the sample inside the test tube.

[0061] Example 4

[0062] On the basis of Example 3, Fig.17 As shown, a disinfection heating ring 12 is also included. The support plate 3 is symmetrically fixed with a disinfection heating ring 12 for high-temperature disinfection of the small syringe 101 and the large syringe 81. At least a portion of the small syringe 101 passes through one of the disinfection heating rings 12, and at least a portion of the large syringe 81 passes through the other disinfection heating ring 12.

[0063] When the small syringe 101 and the large syringe 81 are reset, the disinfection heating ring 12 is started by manually controlling the external device, so that the disinfection heating ring 12 emits heat and performs high-temperature disinfection on the small syringe 101 and the large syringe 81 to prevent samples from remaining on the small syringe 101 and the large syringe 81, which will not affect subsequent test results, thereby achieving the purpose of effectively ensuring the accuracy of the test results.

[0064] Example 5

[0065] On the basis of Example 4, Fig.18 As shown, it also includes a swing component 13, which is used to fully mix the sample and reagent inside the test tube.

The swing gear 131 is fixedly connected to the rotating sleeve 65, and two pairs of fixed racks 132 are connected to the double-slide support frame 61. The fixed rack 132 has a double-tooth block structure, and the two pairs of fixed racks 132 are staggered.

[0066] When the perforated cross 64 and the device thereon move, one of the swinging gears 131 will contact the four fixed racks 132 in sequence. Through the cooperation between the fixed racks 132 and one of the swinging gears 131, one of the swinging gears 131 and the device thereon will swing, so that the sample and reagent inside the test tube are fully mixed, thereby achieving the effect of effectively improving the reaction rate.

[0067] Example 6

[0068] On the basis of Example 5, Fig.19-as shown, it also includes a prompt component 14, which is used to remind the staff to manually take out the injected test tube. The prompt component 14 is arranged on the double-slide support frame 61, and the prompt component 14 includes an L-shaped slotted frame 141, an L-shaped wedge-shaped slide 142, a prompt block 143 and a sixth return spring 144. The double-slide support frame 61 is connected to the L-shaped slotted frame 141, and the interior of the L-shaped slotted frame 141 is a cavity structure. The L double-slide support frame 61 is slidably connected with an L-shaped wedge-shaped slide 142, the L-shaped wedge-shaped slide 142 is located inside the L-shaped slotted frame 141, and the L-shaped wedge slide 142 is fixedly connected with a prompt block 143 for reminding the staff to manually take out the injected test tube. The upper and lower parts of the prompt block 143 are of different colors, and the sixth return spring 144 is connected between the L-shaped wedge slide 142 and the double-slide support frame 61.

[0069] When the open cross 64 away from the multi-directional support frame 62 contacts the L-shaped wedge slide 142, the open cross 64 away from the multi-directional support frame 62 will push the L-shaped wedge slide 142 and the device thereon to move upward, and the sixth return spring 144 will be compressed accordingly, so that the exposed part of the prompt block 143 changes, which is convenient for reminding the staff to manually take out the open cross 64 and the device thereon away from the multi-directional support frame 62, and then the injected test tube can be manually taken out. When the three open crosses 64 are all taken out, the staff manually pushes the multi-directional support frame 62 to move upward, and the sixth return spring 63 will be compressed accordingly, which is convenient for people to manually place the open cross 64 on the double-slide support frame 61 again. Repeating the above operation can use the device to inject reagents again.
