[0027] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail with reference to the drawings.

[0028] The present application provides an immunochromatography test paper card for detecting serum amyloid A as shown in Figures 1-5 The present application provides an immunochromatography test paper card for detecting serum amyloid A as shown in

[0029] The disinfection assembly 6 comprises a liquid storage bottle 601 storing disinfectant, and a sleeve 602 is fixed to the outer end of the liquid storage bottle 601, and a sealing film 607 for closing the sleeve 602 is fixed to the inner wall of the sleeve 602, and the sealing film 607 can be made of polyethylene material.

[0030] One end of the upper protective shell 1 is fixedly provided with a cannula 605, which extends to the inside of the sleeve 602 at the end of the liquid storage bottle 601 and is fixedly provided with a protrusion 606 with a sharp end, and the protrusion 606 can break the sealing film 607, and the sleeve 602 is connected with the cannula 605 through threads.

[0031] Two connecting strips 603 made of plastic are arranged between the liquid storage bottle 601 and the upper protective shell 1, and the two connecting strips 603 are respectively arranged on both sides of the sleeve 602, and an annular groove 604 is formed in the outer end of the connecting strip 603.

[0032] The upper protective shell 1 and the bottom shell 2 form a relatively closed space, and the test strip 9 is closed in the upper protective shell 1, and in the detection process, the liquid storage bottle 601 storing disinfectant is connected to one end of the upper protective shell 1, at this time, the connecting strip 603 is not broken, and the rotation of the liquid storage bottle 601 is limited, and the cannula 605 does not penetrate into the inside of the sleeve 602, and the sealing film 607 remains intact, when the detection work is completed, the liquid storage bottle 601 can be rotated by force, under the action of external force, the connecting strip 603 is broken from the annular groove 604, the liquid storage bottle 601 rotates without restraint, the sleeve 602 rotates with the liquid storage bottle 601, under the action of threads, the cannula 605 moves relative to the sleeve 602 and penetrates into the sleeve 602, until the protrusion 606 contacts the sealing film 607, with the rotation of the sealing film 607, the sealing film 607 is broken by the protrusion 606, and the disinfectant stored in the liquid storage bottle 601 can flow into the upper protective shell 1, so as to disinfect the test strip 9, so as to avoid the spread of diseases by the test strip 9 containing blood components, by arranging the disinfection assembly 6, the test paper card has a disinfection function, and the test strip 9 can be quickly disinfected after detection, which is very convenient and fast.

[0033] After the test strip 9 absorbs the liquid, the situation on the test strip 9 needs to be observed to determine the detection result, as shown in Figure 1 、 3 , 5, the bottom shell 2 is detachably arranged at the bottom end of the upper protective shell 1, and the upper protective shell 1 is inlaid with a transparent window 3 through which the test strip 9 can be observed, and the transparent window 3 can be made of transparent acrylic material.

[0034] The waterproof film 11 is fixed on the top end of the upper protective shell 1 and can be made of PVC material. A sponge pad 8 is fixed on the top end of the waterproof film 11. An accommodating groove 10 is formed on the top end of the sponge pad 8. The strip-shaped test paper 9 is embedded in the accommodating groove 10. The sponge pad 8 can absorb excess liquid and keep the outer surface of the strip-shaped test paper 9 dry.

[0035] The strip-shaped test paper 9 with a detection function is embedded in the accommodating groove 10 on the top end of the sponge pad 8. During detection, part of the liquid dropped on the strip-shaped test paper 9 is absorbed by the strip-shaped test paper 9 for detection. The strip-shaped test paper 9 has limited absorption capacity. The excess part is absorbed by the sponge pad 8, so as to avoid the pollution caused by the excess liquid flowing around the surface of the strip-shaped test paper 9. The sponge pad 8 can also absorb the disinfectant liquid during disinfection, so that the sponge pad 8 wrapped with the disinfectant liquid is wrapped around the outer end of the strip-shaped test paper 9, improving the comprehensiveness of disinfection. During detection, the strip-shaped test paper 9 with the liquid can display the result on the strip-shaped test paper 9 according to the SAA content in the liquid. The detection result on the strip-shaped test paper 9 can be observed through the transparent window 3.

[0036] The liquid to be detected is not directly dropped on the strip-shaped test paper 9. As shown in Figure 3 、 5 , the top end of the upper protective shell 1 is provided with a drop assembly 7. The drop assembly 7 includes an external channel 701. The top end of the external channel 701 is flush with the top end of the upper protective shell 1. The bottom end of the external channel 701 is directed to the strip-shaped test paper 9 inside the upper protective shell 1.

[0037] A liquid-permeable net 702 is fixed on the inner wall of the external channel 701. A sponge block 703 is arranged on the top end of the liquid-permeable net 702. The liquid to be dropped on the strip-shaped test paper 9 is first dropped on the sponge block 703.

[0038] The liquid to be detected is dropped on the sponge block 703 inside the external channel 701. The liquid is quickly absorbed by the sponge block 703 and will not flow around, avoiding pollution.

[0039] In order to squeeze the sponge block 703 with the liquid, as shown in Figure 3 、 5 , the top of the upper protective shell 1 is provided with an elastic film 4 made of rubber. The outer end of the elastic film 4 is fixedly provided with a frame 5. The bottom end of the frame 5 is in contact with the top end of the upper protective shell 1. The elastic film 4 covers the top end of the drop assembly 7. One end of the frame 5 is movably connected to the top end of the upper protective shell 1 through a rotating shaft. The downward pressing of the elastic film 4 can squeeze the external channel 701.

[0040] In daily state, the elastic film 4 covers the top end of the dropping assembly 7, plays a protective role for the dropping assembly 7, and avoids the strip test paper 9 from being polluted; when liquid is dropped, the frame 5 is rotated and the elastic film 4 is removed, the dropping assembly 7 is exposed, the liquid is dropped on the sponge block 703 and is absorbed, then the elastic film 4 is covered on the dropping assembly 7, then the elastic film 4 is pressed downward, the sponge block 703 is pressed downward, the sponge block 703 under the pressure squeezes out the absorbed liquid and drops the liquid through the liquid-permeable net 702 to the strip test paper 9, further avoiding the pollution caused by the liquid flowing everywhere.

[0041] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
