Description

Technical Field

[0001] The utility model belongs to the technical field of detection instruments, in particular to a fluorescence detector with a dustproof reagent card insertion port. Background Art

[0002] Fluorescence detectors play an important role in scientific research, environmental protection, biomedicine, chemistry and other fields. They can detect fluorescent substances in samples and accurately measure their content and fluorescence intensity. When using some fluorescence detectors, the reagent card needs to be inserted into the card carrier before fluorescence detection can be performed.

[0003] As a detection instrument, the fluorescence detector is often needed to detect harmful substances such as drugs, infectious diseases and viruses in police and medical environments. Its detection carriers are mostly urine, saliva and blood. The use of fluorescence detectors in such environments requires attention to various process safety and overcoming the discomfort of most people with other people's secretions. Therefore, the disinfection of the fluorescence detector itself is very important.

[0004] However, most fluorescence detectors on the market are not designed to be sealed and easy to disinfect. The main reason is that the reagent card needs to be inserted into the detection instrument for testing. Some fluorescence detectors need to move the reagent card inside for testing. As a result, the insertion port of the reagent card is directly connected to the internal environment of the fluorescence detector, making it impossible to disinfect the entire machine. Utility Model Content

[0005] The utility model aims to provide a fluorescence detector with a dustproof reagent card insertion port to address the deficiencies in the prior art.

[0006] To this end, the above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0007] A fluorescence detector with a dustproof reagent card insertion port, comprising: a housing, a fluorescence detection component and a reagent card compartment in the housing, characterized in that: the fluorescence detector further comprises an inner and outer isolation component, the inner and outer isolation component is used to isolate the fluorescence detection component and the reagent card compartment;

[0008] The internal and external isolation components include a sealing ring, a protective cover plate, a transparent sealing cover plate, and a fixing plate;

[0009] The shell is provided with an annular placement groove for accommodating the transparent sealing cover plate;

[0010] The sealing ring is used to fit into the gap between the transparent sealing cover plate and the annular placement groove;

[0011] The fixing plate is fixed in the housing, and the sealing ring is pressed between the fixing plate and the transparent sealing cover plate;

[0012] The protective cover plate is attached to the outer side of the transparent sealing cover plate and covers the outer gap between the transparent sealing cover plate and the housing. The area on the protective cover plate that overlaps with the transparent sealing cover plate is at least transparent.

[0013] While adopting the above technical solutions, the present invention can also adopt or combine the following technical solutions:

[0014] As a preferred technical solution of the utility model: the side of the transparent sealing cover plate has a step portion, and the step portion on the side of the transparent sealing cover plate is mounted on the annular placement groove to fit with the annular placement groove.

[0015] As a preferred technical solution of the utility model: the transparent sealing cover is K9 optical glass.

[0016] As a preferred technical solution of the utility model: the protective cover is entirely transparent.

[0017] As a preferred technical solution of the utility model: one end of the reagent card compartment is connected to the housing via a pin, and one end of the reagent card compartment is fixed to the housing via a screw.

[0018] The utility model provides a fluorescence detector with a dustproof reagent card insertion port. By setting an inner and outer isolation component, the fluorescence detection component and the reagent card compartment are isolated, so that only the inside of the reagent card compartment needs to be disinfected. For this purpose, a transparent sealing cover plate, a sealing ring and a fixing plate are particularly provided to form the main part of the inner and outer isolation component to form an effective isolation between the fluorescence detection component and the reagent card compartment. In addition, only the above-mentioned setting will also cause the following problems: during conventional wiping and cleaning, dirt is easily swept into the outer gap between the transparent sealing cover plate and the shell, making it impossible to clean the gap. For this reason, the utility model also sets a protective cover plate on the outer side of the transparent sealing cover plate to cover the outer gap between the transparent sealing cover plate and the shell, which is convenient for cleaning and replacement, and can avoid and reduce the dilemma of dirt entering the gap. Furthermore, one end of the reagent card compartment is connected to the shell by a pin shaft, and the other end is fixed to the shell by a screw. When cleaning the reagent card compartment and the fluorescence detection area (that is, the area covered by the transparent sealing cover), you only need to loosen the screws on the reagent card compartment. Since the other end is fixed to the shell by the pin shaft, you can open the reagent card compartment. After cleaning, close the reagent card compartment and tighten the screws. The operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0024] A fluorescence detector with a dustproof reagent card insertion port, comprising: a housing 100 and a fluorescence detection component 200, a displacement component 300, and a reagent card compartment 500 in the housing 100;

[0025] The fluorescence detection assembly 200 generally includes a light source, a series of optical components and a detector. The light source is used to excite the fluorescent substance in the sample. The optical components are used to focus and filter the fluorescent signal. The detector is used to detect and process the fluorescent signal.

[0026] The displacement assembly 300 is used to translate the fluorescence detection assembly 200 left and right.

[0027] The above fluorescence detection component 200 and displacement component 300 belong to conventional prior art and will not be elaborated on in detail.

[0028] The reagent card compartment 500 is used to insert the reagent card 600 .

[0029] The fluorescence detector further includes an internal and external isolation component 400, which is used to isolate the fluorescence detection component 200 and the reagent card compartment 500;

[0030] The internal and external isolation assembly 400 includes a sealing ring 401, a protective cover plate 402, a transparent sealing cover plate 403, and a fixing plate 404;

[0031] The housing 100 is provided with an annular placement groove 101 for accommodating the transparent sealing cover plate 403;

[0032] The sealing ring 401 is used to fit into the gap between the transparent sealing cover plate 403 and the annular placement groove 101;

[0033] The fixing plate 404 is fixed to the housing 100 , and the sealing ring 401 is pressed between the fixing plate 404 and the transparent sealing cover plate 403 ;

[0034] The protective cover plate 402 is attached to the outside of the transparent sealing cover plate 403 and covers the outer gap between the transparent sealing cover plate 403 and the housing 100. The area on the protective cover plate 402 that overlaps with the transparent sealing cover plate 403 is at least transparent. During conventional wiping cleaning, dirt is easily swept into the gaps of the structure, making the gaps impossible to clean. The utility model can avoid and greatly reduce the dilemma of dirt entering the gaps. The transparent protective cover plate 402 is tightly attached to the housing 100 and the transparent sealing cover plate 403, and the surface gap between the two is covered. When cleaning, it is only necessary to replace the protective cover plate 402 and clean the traces between the protective cover plate 402 and the housing 100. The traces are all above the object plane, which is convenient for cleaning.

[0035] The side of the transparent sealing cover plate 403 has a step portion 403 a , and the step portion 403 a on the side of the transparent sealing cover plate 403 is supported on the annular placement groove 101 to fit with the annular placement groove 101 .

[0036] The transparent sealing cover plate 403 is K9 optical glass. While meeting the high light transmittance and thus not affecting the fluorescence detection, its structural strength is also excellent. The transparent structural material is used to prevent the reagent card from polluting the inside of the fluorescence instrument, and will not affect the optical path of the fluorescence detection; in this embodiment, the fluorescence detection mode with the reagent card fixed is used as an example for explanation, which does not mean that the mobile reagent card for fluorescence detection is not applicable to the technical solution claimed for protection of the utility model. As long as the reagent card is isolated from the main components in the fluorescence instrument by the transparent structural material, it falls within the protection scope of the utility model.

[0037] In particular, the protective cover plate 402 may be configured to be entirely transparent. Of course, in other embodiments, the protective cover plate 402 may be configured to be at least transparent in the area overlapping with the transparent sealing cover plate 403 .

[0038] One end of the reagent card compartment 500 is connected to the housing 100 via a pin shaft (a pin hole 501 is provided on the reagent card compartment 500 ), and one end of the reagent card compartment 500 is fixed to the housing 100 via a screw, so as to facilitate opening the reagent card compartment 500 and cleaning the interior.

[0039] The above-mentioned specific implementation methods are used to explain the present invention and are only preferred embodiments of the present invention, rather than limiting the present invention. Any modifications, equivalent substitutions, improvements, etc. made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
