Description

Technical Field

[0001] The utility model relates to the field of fluorescence detection kits, and particularly to a searchlight device for a fluorescence detection kit with anti-interference function. Background Art

[0002] A fluorescence detection kit is a tool for detecting biomolecules using fluorescence labeling technology, which is widely used in biological research, medical diagnosis, forensic medicine and other fields. The principle of the fluorescence detection kit is mainly based on the fluorescence PCR (polymerase chain reaction) method. This method is a molecular biology technique used to amplify specific DNA fragments. The fluorescence PCR method uses polymerase chain reaction to greatly increase the amount of trace DNA, so as to detect viruses or other biological substances containing specific gene fragments. In this process, first, the trace viral RNA in the sample is reverse transcribed into DNA, and then polymerase chain reaction is used for large-scale amplification for detection. In this way, even very small amounts of DNA can be effectively amplified and detected, making this method have extremely high sensitivity and specificity in the fields of medical diagnosis, virus detection, etc.

[0003] For example, a fluorescence detection kit based on Y-STR loci and Y-Indel and its use method and application provided by the patent number and publication number CN113025725A uses fluorescence detection technology to detect DNA.

[0004] However, since the fluorescence is usually displayed after being irradiated by long-wavelength rays such as ultraviolet rays or X-rays, when the content of the substance to be detected is small or the external light is complex, resulting in poor fluorescence color development effect, it is not easy for the human eye to observe, and the detection result is prone to misreading.

[0018] The following further details the specific embodiments of the present utility model. It should be understood that the description of the present utility model herein is not intended to limit the protection scope of the present utility model.

[0019] As Figures 1 to 3 shown, this is a schematic structural diagram of a searchlight device for an anti-interference fluorescence detection kit provided by the present utility model. The anti-interference fluorescence detection kit searchlight device includes a searchlight unit 10, a light-shielding cover 20 disposed on one side of the searchlight unit 10, and a protective cover 30 disposed on one side of the light-shielding cover 20. It can be conceived that the anti-interference fluorescence detection kit searchlight device should also include some other functional components, such as installation components, electrical connection components, etc., which are all well-known prior arts to those skilled in the art and will not be elaborated herein.

[0020] The searchlight unit 10 includes a lamp base 11 and a searchlight assembly 12 fixedly disposed on the lamp base 11 for irradiating the fluorescence detection kit.

[0021] The lamp base 11 includes a mounting portion 111, a socket hole 112 opened on the mounting portion 111, and a plug portion 113 inserted into the socket hole 112.

[0022] The mounting portion 111 and the plug portion 113 are connected in a T shape, so as to facilitate the installation of the lamp base 11 on the light-shielding cover 20 and is beneficial to observing the detection result of the fluorescence detection kit through the plug portion 113. The mounting portion 111 is a rectangular plate body and is used for disposing the searchlight assembly 12.

[0023] The insertion hole 112 is centrally disposed on the mounting portion 111, and the insertion hole 112 is a through hole that is matched with the insertion portion 113. The insertion hole 112 is used to dispose the insertion portion 113, so that the insertion portion 113 can be mounted on the mounting portion 111 to form an integral body.

[0024] The insertion portion 113 includes an insertion portion main body 1131, a light-shielding cylinder 1132 disposed at one end of the insertion portion main body 1131, and a viewing hole 1133 disposed on the insertion portion main body 1131. The outer contour of the insertion portion main body 1131 is larger than the contour of the insertion hole 112, so as to form a limit when connected to the mounting portion 111. The light-shielding cylinder 1132 is fixedly connected to one end of the insertion portion main body 1131 facing the mounting portion 111. When the insertion portion 113 is connected to the mounting portion 111, the light-shielding cylinder 1132 is inserted into the insertion hole 112, so that the insertion portion 113 is mounted in the insertion hole 112. Further, the extending length of the light-shielding cylinder 1132 is greater than the thickness of the mounting portion 111, so that one end of the light-shielding cylinder 1132 can extend out of the insertion hole 112 after being inserted into the insertion hole 112, thereby blocking the light on both sides of the insertion hole 112 to prevent the searchlight emitted by the searchlight assembly 12 from entering the viewing hole 1133 and affecting the observation. The viewing hole 1133 is formed through the insertion portion main body 1131 along the extending direction of the insertion portion main body 1131, and is used to observe the detection result of the fluorescence detection kit.

[0025] The searchlight assembly 12 includes a plurality of mounting holes 121 respectively arranged at intervals on both sides of the light-shielding cylinder 1132, a plurality of searchlights 122 correspondingly arranged in the mounting holes 121, and a battery 123 fixedly arranged on the mounting portion 111 and used to drive the searchlights 122.

[0026] The mounting holes 121 are disposed on the mounting portion 111 and are arranged on both sides of the light-shielding cylinder 1132 along the length direction of the light-shielding cylinder 1132. The number of the mounting holes 121 is the same as the number of the required searchlights 122, and the shape and size of the mounting holes 121 are all matched with the searchlights 12, so as to facilitate the installation of the searchlights 122 in the mounting holes 121.

[0027] The searchlights 122 are fixedly installed in the mounting holes 121, and the searchlights 122 are long-wavelength searchlights that can make the fluorescent agent emit light, such as ultraviolet lamps. The searchlights 122 are used to irradiate the fluorescence detection kit so that the fluorescent reagent shows color, facilitating the observation of the detection result. The searchlights 122 are well-known prior art to those skilled in the art and will not be elaborated here.

[0028] The battery 123 is fixedly arranged on the side of the mounting part 111 opposite to the searchlight assembly 12 and is used to drive the searchlight assembly to emit light. It can be imagined that a connecting wire (not shown in the figure) should also be arranged between the battery 123 and the searchlight 122 to connect the battery 123 and the searchlight 122. The battery 123 itself is a prior art and will not be elaborated here.

[0029] The light shield 20 is arranged on the side of the lamp holder 11 where the searchlight 122 is arranged, and it includes a light shield main body 21, a reagent kit accommodating groove 22 arranged inside the light shield main body 21, and a lamp holder mounting ring 23 arranged inside the reagent kit accommodating groove 22.

[0030] The light shield main body 21 is used to block external natural light, lights, etc., so as to avoid external light interfering with the color development of the fluorescence detection reagent kit, resulting in the detection result of the fluorescence detection reagent kit being unfavorable for human eye observation.

[0031] The reagent kit accommodating groove 22 is used to accommodate the fluorescence addition test reagent kit, so that the covering cover 20 can mask the fluorescence detection reagent kit during observation, which is convenient for observation. The contour of the reagent kit accommodating groove 22 matches the outer contour of the mounting part 111, so as to facilitate the lamp holder 11 to be installed and accommodated inside the reagent kit accommodating groove 22.

[0032] The lamp holder mounting ring 23 is fixedly arranged on the side of the reagent kit accommodating groove 22 facing the lamp holder 11. The inner contour of the lamp holder mounting ring 23 is smaller than the outer contour of the mounting part 111, so as to provide support for the mounting part 111 and facilitate the installation of the lamp holder 11 in the reagent kit accommodating groove 22.

[0033] The protective cover 30 includes a protective cover main body 31, a positioning hole 32 arranged on one side of the protective cover main body 31, and a lighting lamp control switch 33 arranged on the protective cover main body 31.

[0034] The protective cover main body 31 covers the outside of the searchlight unit 10 and is used to protect the lamp holder 11 and the searchlight assembly 12 mounted on the lamp holder 11. The protective cover 30 is arranged in a matching manner with the light shield 20, so that the light shield 20 and the protective cover 30 form a complete housing.

[0035] The positioning hole 32 is a through hole correspondingly provided on the protective cover body 31 for the plug-in part body 1131. The inner contour of the positioning hole 32 is adapted to the outer contour of the plug-in part body 1131. When the protective cover 30 is sleeved outside the searchlight unit 10, one end of the plug-in part body 1131 is inserted into the positioning hole 32, so as to fix the position of the protective cover 30.

[0036] The illumination lamp control switch 33 can be arranged on one side of the protective cover body 31 together with the positioning hole 32, and is used to control the battery 123, so as to control the on and off of the searchlight 122. It can be imagined that the illumination lamp control switch 33, the searchlight 122, and the battery 123 are connected to each other by wires (not shown in the figure) to form a control circuit. The illumination lamp control switch 33 itself is a kind of prior art and will not be elaborated here.

[0037] Compared with the prior art, for the anti-interference fluorescence detection kit searchlight device provided by the present invention, a light-shielding cover 20 is arranged on the side of the searchlight unit 10 where the searchlight assembly 12 is arranged. The light-shielding cover 20 includes a light-shielding cover body 21 and a kit accommodating groove 22 arranged inside the light-shielding cover body 21. When it is necessary to read the detection result of the fluorescence detection kit, the fluorescence detection kit is placed in the kit accommodating groove 22, and then the searchlight 122 is turned on to irradiate the fluorescence detection kit to make it develop color. At the same time, the light-shielding cover body 21 can block external natural light or lights, etc., so as to avoid the interference of external light on the color development result of the fluorescence detection kit, resulting in the detection result of the fluorescence detection kit being not conducive to human eye observation, and improving the reading accuracy of the detection result of the fluorescence detection kit.
