Description

Technical Field

[0001] This utility model relates to the field of detection kit technology, specifically a light-proof and anti-evaporation respiratory pathogen detection kit. Background Technology

[0002] Respiratory tract infections are among the most common clinical diseases worldwide. The pathogens that can cause respiratory tract infections are very complex, including bacteria, viruses, mycoplasma, chlamydia, etc., and their clinical manifestations and treatments vary.

[0003] Utility model patent CN215833422U discloses a respiratory pathogen detection kit for children. The kit includes a box body with a hinged lid at the top. The box body is divided into three areas by a partition: a sampling area, a waste area, and a reagent storage area. The sampling area contains several sampling needles, and the reagent storage area stores multiple respiratory pathogen detection plates. This kit incorporates respiratory pathogen detection plates, allowing for the simultaneous detection of multiple viruses from the same blood sample, thus broadening its application range.

[0004] While the aforementioned inventions can simultaneously detect multiple viruses using the same blood sample and have a wide range of applications, some respiratory pathogen detection antigens are photosensitive, and these antigens may denature under light, leading to inaccurate detection results. Therefore, we propose a light-protected, anti-evaporation respiratory pathogen detection kit. Utility Model Content

[0005] This invention provides a light-proof and anti-evaporation respiratory pathogen detection kit to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A light-proof and anti-evaporation respiratory pathogen detection kit includes a detection box, wherein the detection box contains a detection mechanism, and the detection mechanism includes a detection tray and a light-proof mechanism covering the upper end of the detection tray; The light-shielding mechanism includes a light-shielding cover, four auxiliary pieces fused to the left and right ends of the front and rear surfaces of the light-shielding cover, and a feeding channel fused to the left side of the upper surface of the light-shielding cover. The upper end of the feeding channel is covered with a feeding cover. Insert rods are fused to the four corners of the lower surface of the light-shielding cover, and a gathering plate is fused to the left side of the lower surface of the light-shielding cover.

[0007] As a preferred technical solution, slots are provided at the four corners of the upper surface of the detection disk, and the slots are connected to the insertion rod.

[0008] This design, with its plug-in structure, enables quick positioning and secure assembly of the light-shielding cover and the detection plate, preventing light leakage caused by cover misalignment.

[0009] As a preferred technical solution, the feeding channel is cylindrical, and the upper surface of the light-shielding cover within the range of the feeding channel is provided with a feeding port.

[0010] This design places the feed inlet only in a localized area of ​​the light-shielding cover, preventing light from entering due to a large opening and enhancing overall light-shielding performance.

[0011] As a preferred technical solution, the feed cover is in the shape of a circular piece, the right end of the feed cover is fused to the right end of the upper surface of the feed channel by plastic, and an auxiliary strip is fused to the left end of the feed cover.

[0012] This design, with its molten plastic connection, creates a single integrated structure between the feed cover and the channel, preventing loss and ensuring a tight seal when closed.

[0013] As a preferred technical solution, a rubber ring for engaging with the inner side surface of the feed channel is fused to the lower surface of the feed cover, and the words "feed port" are hot-stamped on the upper surface of the feed cover.

[0014] This feature uses a rubber ring to seal the feed inlet, reducing sample or reagent evaporation during testing and further blocking light from entering.

[0015] As a preferred technical solution, the gathering plate covers the lower side of the feeding channel, and the gathering plate has a hollow frustum-shaped structure that is wider at the top and narrower at the bottom.

[0016] This design, with its frustum-shaped structure, guides and gathers the sample injected from the feed channel, preventing it from splashing outside the detection area and ensuring detection efficiency.

[0017] As a preferred technical solution, a barrier is fused around the lower surface of the light-shielding cover, and when the insertion rod is inserted into the bottom of the slot, the barrier fits tightly against the upper surface of the detection plate.

[0018] This design, with the tight fit between the enclosure and the detection panel forming a circumferential seal, effectively prevents external light from seeping in from the edges of the cover, enhancing the reliability of light protection.

[0019] As a preferred technical solution, the top view size of the light-shielding cover is larger than the top view size of the detection area of ​​the detection disc, and anti-slip textures are provided on the side surface of the light-shielding cover and the side surface of the enclosure.

[0020] This feature, with its anti-slip texture, increases grip friction, making it easier to install and remove the sunshade and improving usability.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. Before and during testing, cover the antigen with a light-shielding cover to prevent the photosensitive antigen from being exposed to light, which could cause denaturation and affect the test results.

[0022] 2. By covering the testing tray, the evaporation of the blood sample can be prevented, which would cause changes in the blood sample concentration and affect the test results. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-5 This embodiment provides a technical solution: A light-proof and anti-evaporation respiratory pathogen detection kit includes a detection box 100, and a detection mechanism 200 is provided inside the detection box 100. The detection mechanism 200 includes a detection tray 210 and a light-proof mechanism 220 covering the upper end of the detection tray 210. The light-shielding mechanism 220 includes a light-shielding cover 221, four auxiliary pieces 222 fused to the left and right ends of the front and rear surfaces of the light-shielding cover 221, and a feeding channel 223 fused to the left side of the upper surface of the light-shielding cover 221. The upper end of the feeding channel 223 is covered with a feeding cover 224. Insert rods 225 are fused to the four corners of the lower surface of the light-shielding cover 221. A gathering plate 226 is fused to the left side of the lower surface of the light-shielding cover 221. Through the above mechanism, the detection area can be completely covered during the detection of respiratory pathogens through antigens, preventing light from affecting the photosensitive antigens and causing abnormal detection. Covering the area can also prevent the evaporation of the test sample from causing changes in concentration and affecting the detection effect.

[0026] It should be added that the enclosure is made of rubber material and is pressed and adhered to the upper surface of the detection panel 210, so that the detection panel 210 and the light shield 221 are sealed after being closed.

[0027] Furthermore, such as Figure 3 As shown, slots 211 are provided at the four corners of the upper surface of the detection plate 210. The slots 211 are connected to the plug rods 225, and the light shield 221 is fixed to the upper end of the detection plate 210 through the plug connection.

[0028] Furthermore, such as Figure 4 As shown, the feeding channel 223 is cylindrical. The upper surface of the light-shielding cover 221 within the feeding channel 223 has a feeding port. The feeding cover 224 is circular. The right end of the feeding cover 224 is connected to the right end of the upper surface of the feeding channel 223 by plastic fusion. An auxiliary strip is fused to the left end of the feeding cover 224. A rubber ring for engaging with the inner side surface of the feeding channel 223 is fused to the lower surface of the feeding cover 224. The words "feeding port" are hot-stamped on the upper surface of the feeding cover 224 to clearly indicate the location of the feeding channel 223 and prevent users from accidentally removing the light-shielding cover 221 before testing, which would cause some photosensitive antigens to denature due to light exposure and affect the test results.

[0029] In this embodiment, as Figure 5 As shown, the gathering plate 226 covers the lower side of the feeding channel 223. The gathering plate 226 has a hollow frustum-shaped structure that is wider at the top and narrower at the bottom. The lower surface of the light shield 221 is fused with a baffle. When the insertion rod 225 is inserted into the bottom of the slot 211, the baffle is tightly fitted to the upper surface of the detection plate 210. The tight fit achieves a seal, ensuring light shielding while preventing sample evaporation.

[0030] In this embodiment, as Figure 2 As shown, the top view size of the light shield 221 is larger than the top view size of the detection area of ​​the detection plate 210. The side surface of the light shield 221 and the side surface of the enclosure are provided with anti-slip texture to increase the friction generated by the user's grip, making it easier for the user to remove the light shield 221.

[0031] It is worth noting that the structure and working principle of the detection box 100 and detection disk 210 involved in this embodiment are all technologies that have been disclosed in the prior art, and will not be described in detail here.

[0032] In the specific use of the light-proof and anti-evaporation respiratory pathogen detection kit of this embodiment, the sample to be tested is first taken out from the detection box 100, then a detection unit 200 is taken out from the detection box 100, and then the feed cover 224 is opened. The sample is fed in through the feed channel 223, passes through the feed inlet and the gathering plate 226, and finally enters the feed area on the detection tray 210. The feed cover 224 is closed and the sample is allowed to react with the antigen. After a certain period of time, the light-proof cover 221 is removed by holding the detection tray 210 with one hand and pinching the side surface of the light-proof cover 221 or the auxiliary sheet with the other hand. The state of the antigen on the detection tray 210 is observed and the detection result is obtained.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
