Description

Technical Field

[0001] The utility model relates to the technical field of detection kits, in particular to a dengue fever NS1 antigen detection kit. Background Art

[0002] Dengue fever is a pandemic virus. The Dengue Rapid Test Kit is a qualitative test for the detection of dengue virus IgM and IgG antibodies in human serum, plasma, and whole blood. This test can differentiate between primary and secondary infection. It should only be used on samples from patients with clinical symptoms of dengue fever. Results are presumptive positive and must be confirmed by virus isolation in duplicate serum analysis, immunohistochemistry for antigen detection, or viral nucleic acid testing.

[0003] Currently, the test kit needs to be used in conjunction with a pipette, a lancet, etc. When used, the finger needs to be pricked with the lancet first, and then the blood flowing out of the finger needs to be sucked out with a pipette, and then the blood in the pipette is transferred to the sample addition hole of the test kit. From the above, it can be seen that the blood needs to be transferred through a pipette, and the operation is cumbersome. For non-professionals using the test for the first time, it will bring certain operational difficulties, especially for users who feel uncomfortable when seeing blood. Using a pipette to suck and transfer blood will increase the time the user sees the blood, which is more inconvenient for their use. Moreover, the test kit is separated from the pipette, lancet, etc., and is not convenient to store and carry. Therefore, a dengue fever NS1 antigen detection kit is proposed to address the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A dengue fever NS1 antigen detection kit includes a kit body and a test paper. The test paper is fixedly connected to the inner side of the kit body. A guide column is provided on the inner side of the sample addition hole of the kit body, and the bottom end of the guide column penetrates the test paper and is fixedly connected to the inner side of the bottom end of the kit body. A through hole is opened on the inner side of the guide column, and the guide column is slidably connected to a puncture needle through the through hole. A pressing mechanism is provided at the bottom of the puncture needle, and the diameter of the through hole is the same as that of the puncture needle.

[0007] Preferably, the pressing mechanism comprises a connecting plate fixedly connected to the reagent kit body, one end of the connecting plate is slidably connected to a pressing plate, and the pressing plate is fixedly connected to the puncture needle.

[0008] Preferably, one end of the connecting plate is fixedly connected to a fixing plate, the bottom end of the fixing plate is fixedly connected to a spring, and the spring is fixedly connected to the pressing plate, and the spring gives the pressing plate a downward elastic force.

[0009] Preferably, one end of the connecting plate is fixedly connected to a limiting block, and the limiting block is arranged above the pressing plate.

[0011] Preferably, the guide column is evenly and fixedly connected with guide ribs 11 on all sides, and the number of the guide ribs 11 is four.

[0012] Preferably, when the bottom end surface of the pressing plate is in contact with the connecting plate, the top end surface of the needle is flush with the top end surface of the guide column.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The dengue fever NS1 antigen detection kit is provided with a pressure plate, a lancet, a guide column, and a guide rib 11. When the kit body needs to be used for detection, the user presses the pressure plate, so that the pressure plate extends from the inner side of the guide column with the lancet and pierces the finger, and then releases the pressure plate. At this time, under the elastic force of the spring, the pressure plate will return to the inner side of the guide column with the lancet, and pierce the user's finger with the lancet. Then, the staff member points the finger downward and places the punctured part of the finger on the guide column and the guide rib. At this time, the blood flowing out of the finger will quickly flow along the guide column and the guide rib to the inner side of the sample addition hole, and there is no need to transfer the blood vessel through a straw, which is convenient for non-professionals to use for the first time. Moreover, when bleeding, the finger is downward, and the finger will block the blood, thereby reducing the time the user sees the blood. It is also convenient for users who feel uncomfortable when seeing the blood. In addition, the device combines the lancet with the kit body as one, and does not use a straw, which is also convenient for the user to carry and store.

[0015] 2. The dengue fever NS1 antigen detection kit has a limit block that prevents the movement of the pressure plate, ensuring that the needle does not penetrate too deeply into the skin, thus protecting the fingers. BRIEF DESCRIPTION OF THE DRAWINGS

The guide column 10 can accelerate the flow of blood downward. A through hole 12 is opened on the inner side of the guide column 10. The guide column 10 is slidably connected to a lancet 9 through the through hole 12. The bottom of the lancet 9 is provided with a pressing mechanism, and the through hole 12 is provided with a pressing mechanism. The diameter is the same as that of the puncture needle 9, which prevents blood from flowing into the inner side of the through hole 12. The blood flowing out of the finger will quickly flow to the inner side of the sample addition hole along the guide column 10 and the guide rib 11, and there is no need to transfer the blood vessel through a straw, which is convenient for non-professionals to use for the first time. When bleeding, the finger is downward, and the finger will block the blood, thereby reducing the time the user sees the blood, and is also convenient for users who feel uncomfortable when seeing blood. In addition, the device combines the puncture needle 9 with the reagent kit body 1 as a whole, and does not use a straw, which is also convenient for users to carry and store.

[0025] As a further improvement of the present invention, Figure 1 、 Figure 2 and Figure 3 As shown, the pressing mechanism includes a connecting plate 4 fixedly connected to the reagent kit body 1, one end of the connecting plate 4 is slidably connected to a pressing plate 8, and the pressing plate 8 is fixedly connected to the puncture needle 9, so that the user can press the puncture needle 9 through the pressing plate 8.

[0026] As a further improvement of the present invention, Figure 2 and Figure 3 As shown, one end of the connecting plate 4 is fixedly connected to a fixing plate 5, the bottom end of the fixing plate 5 is fixedly connected to a spring 6, and the spring 6 is fixedly connected to the pressure plate 8, and the spring 6 gives the pressure plate 8 a downward elastic force. Under the elastic force of the spring 6, the pressure plate 8 can be quickly retracted with the puncture needle 9 to the inner side of the guide column 10.

[0027] As a further improvement of the present invention, Figure 2 and Figure 3 As shown, one end of the connecting plate 4 is fixedly connected to the limit block 7, and the limit block 7 is arranged above the pressure plate 8. The limit block 7 will prevent the movement of the pressure plate 8, ensuring that the needle 9 will not penetrate too deeply into the skin, thereby protecting the fingers.

[0028] As a further improvement of the present invention, Figure 1 As shown, the four corners of the bottom of the reagent box body 1 are fixedly connected with support legs 3, and the support legs 3 can make the device be placed stably on the table to prevent the blood inside the sample addition hole from flowing out.

[0031] Working process: When the test kit body 1 is needed for testing, the user presses the pressing plate 8, so that the pressing plate 8 with the puncture needle 9 extends from the inner side of the guide column 10 and punctures the finger, and then releases the pressing plate 8. At the same time, the limit block 7 will prevent the movement of the pressing plate 8 to ensure that the puncture needle 9 does not penetrate too deeply into the skin, thereby protecting the finger. At this time, under the elastic force of the spring 6, the pressing plate 8 will return to the inner side of the guide column 10 with the puncture needle 9, and puncture the user's finger with the puncture needle 9. Then the staff puts the finger downward and puts the puncture site of the finger on the guide column. At the flow column 10 and the guide rib 11, the blood flowing out of the finger will quickly flow to the inner side of the sample addition hole along the guide column 10 and the guide rib 11, and there is no need to transfer the blood vessel through a straw, which is convenient for non-professionals to use for the first time. When bleeding, the finger is downward, and the finger will block the blood, thereby reducing the time the user sees the blood, and is also convenient for users who feel uncomfortable when seeing blood. In addition, the device combines the puncture needle 9 with the reagent kit body 1 as a whole, and does not use a straw, which is also convenient for users to carry and store.
