Description

Technical Field

[0001] This utility model relates to the field of fluorescence quantitative detection card technology, specifically a salbutamol fluorescence quantitative detection card. Background Technology

[0002] Salbutamol is a β2 receptor agonist that dilates bronchial smooth muscle and is used to treat various types of bronchial asthma and various bronchial and lung diseases accompanied by bronchospasm. However, it is also illegally used as a growth promoter for livestock and poultry, which may cause food poisoning and seriously threaten human health. Therefore, the detection of salbutamol is of great significance to ensure food safety and public health. Salbutamol is detected by fluorescent quantitative detection card.

[0003] A fluorescence quantitative detection card is a rapid detection tool based on fluorescence quantitative technology. It is mainly used to determine the content of specific components in a sample. Its working principle is to use specific fluorescent reagents to bind with target ions to generate fluorescence signals, and to quantitatively analyze the concentration of target components by measuring the fluorescence intensity.

[0004] However, the test strip and the outer shell of the fluorescence quantitative detection card are integrated. After the fluorescence quantitative detection card is used, the entire fluorescent quantitative detection card needs to be discarded. The outer shell of the fluorescent quantitative detection card is made of plastic and can be reused, which increases the cost of using the fluorescent quantitative detection card. Therefore, it does not meet the current needs. In response, we have proposed a salbutamol fluorescence quantitative detection card. Utility Model Content

[0005] The purpose of this invention is to provide a fluorescent quantitative analyte test strip to solve the problems mentioned in the background art, such as the fluorescent quantitative analyte test strip and the outer shell of the test strip being integrated, requiring the entire fluorescent quantitative analyte test strip to be discarded after use, and the outer shell of the fluorescent quantitative analyte test strip being made of plastic and reusable, leading to increased usage costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a salbutamol fluorescence quantitative detection card, comprising a main housing of the detection card, a test strip mounting groove inside the main housing of the detection card, a detection card end block detachably mounted at one end of the main housing of the detection card, a squeeze button slidably mounted on the upper and lower surfaces of the test card end block, a connecting spring fixed between the two squeeze buttons, a test strip receiving groove on the end face of the test card end block facing the main housing of the detection card, two upper and lower symmetrical anti-detachment elastic receiving plates fixedly mounted on the inner side of the test strip receiving groove, one end of the anti-detachment elastic receiving plate being fixed to the inner end face of the test strip receiving groove, the other end of the anti-detachment elastic receiving plate being inserted into the inner side of the test strip mounting groove, and a squeeze plate being provided between the anti-detachment elastic receiving plate and the squeeze button.

[0007] Preferably, one end of the test strip mounting groove is flush with one end face of the main housing of the test card, and the top and bottom surfaces of this end of the test strip mounting groove are provided with spherical grooves.

[0008] Preferably, the surface of the anti-detachment elastic snap-fit ​​plate that adheres to the main housing of the detection card is provided with spherical protrusions, and the spherical protrusions are snapped into spherical grooves.

[0009] Preferably, the outer surface of the end of the squeeze button located inside the detection card block is provided with a positioning slot, and one end of the squeeze plate is engaged inside the positioning slot.

[0010] Preferably, the middle part of the extrusion plate is inclined at a 15-degree angle to the end that connects to the extrusion plate and the extrusion button, and the end of the extrusion plate that contacts the anti-detachment elastic snap plate is perpendicular to and in contact with the anti-detachment elastic snap plate.

[0011] Preferably, the inner side of the test paper mounting groove is provided with a test paper guide slope, and the inclination angle of the test paper guide slope is forty-five degrees.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a salbutamol fluorescence quantitative detection card includes a main housing 1, a test strip mounting groove 4 inside the main housing 1, and a test strip guiding slope 5 on the inner side of the test strip mounting groove 4. The inclined angle of the test strip guiding slope 5 is 45 degrees. The test strip guiding slope 5 guides the end of the test strip inserted into the test strip mounting groove 4, so that the detection surface of the test strip is in contact with the observation window and the bottom of the reagent addition hole on the surface of the main housing 1 of the detection card.

[0022] A test card end block 2 is detachably installed at one end of the main housing 1 of the test card. Squeeze buttons 3 are slidably installed on both the upper and lower surfaces of the test card end block 2. A connecting spring 8 is fixed between the two squeeze buttons 3. A test strip receiving groove 6 is provided on the end face of the test card end block 2 facing the main housing 1 of the test card. Two symmetrical anti-detachment elastic retaining plates 7 are fixed on the inner side of the test strip receiving groove 6. One end of the anti-detachment elastic retaining plate 7 is fixed to the inner end face of the test strip receiving groove 6, and the other end of the anti-detachment elastic retaining plate 7 is inserted into the inner side of the test strip mounting groove 4. A squeeze plate 10 is provided between the anti-detachment elastic retaining plate 7 and the squeeze button 3. The test card end block 2 is connected to the main housing 1 of the test card using the anti-detachment elastic retaining plate 7. After the anti-detachment elastic retaining plate 7 is separated from the main housing 1 of the test card, the test card end block 2 can be separated from the main housing 1 of the test card, and the test strip in the main housing 1 of the test card can be extracted through the test card end block 2.

[0023] One end of the test strip mounting groove 4 is flush with one end face of the main housing 1 of the test card, and the top and bottom surfaces of this end of the test strip mounting groove 4 are provided with spherical grooves. The anti-detachment elastic snap-fit ​​plate 7 has spherical protrusions on the surface of the main housing 1 of the test card. The spherical protrusions are snapped into the spherical grooves to ensure the structural stability of the test card end block 2 after it is connected to the main housing 1 of the test card, and the test card end block 2 and the main housing 1 of the test card will not easily separate without human intervention.

[0024] The squeeze button 3 is located on the outer surface of the end of the inner side of the test card end block 2, and a positioning groove is provided. One end of the squeeze plate 10 is engaged in the inner side of the positioning groove. The middle part of the squeeze plate 10 is inclined at a 15-degree angle to the end of the squeeze plate 10 and the squeeze button 3. The end of the squeeze plate 10 that contacts the anti-detachment elastic snap-fit ​​plate 7 is perpendicular to and in contact with the anti-detachment elastic snap-fit ​​plate 7, so that when the squeeze button 3 is squeezed, it drives the squeeze plate 10 to slide, so that the squeeze plate 10 squeezes the anti-detachment elastic snap-fit ​​plate 7 and causes the anti-detachment elastic snap-fit ​​plate 7 to bend and deform towards the middle of the test paper snap-fit ​​groove 6, so that the surface of the anti-detachment elastic snap-fit ​​plate 7 that is in contact with the main housing 1 of the test card is separated from the main housing 1 of the test card, thereby separating the test card end block 2 from the main housing 1 of the test card.

[0025] Working principle: When using a fluorescent detection card to detect salbutamol, salbutamol reagent is added to the reagent addition hole on the surface of the main housing 1 of the detection card. The salbutamol reagent in the reagent addition hole is absorbed by the test paper. After the test paper absorbs the salbutamol reagent, the structure is displayed. The tester observes and records the results through the observation window on the surface of the main housing 1 of the detection card. After the test, the tester only needs to squeeze the two squeeze buttons 3, causing the squeeze buttons 3 to retract into the end block 2 of the detection card and drive the squeeze plate 10 to move, so that the squeeze plate 10 engages with the anti-detachment elastic snap plate 7. When squeezed, the anti-detachment elastic snap plate 7 bends and deforms, and the surface in contact with the main housing 1 of the test card separates from the main housing 1 of the test card. This prevents the anti-detachment elastic snap plate 7 from continuing to connect and fix the main housing 1 of the test card. At this time, simply pull the end block 2 of the test card to remove the test paper from the main housing 1 of the test card. Then, remove the test paper from the test paper slot 6 and replace it with a new test paper. The replaced test paper and the end block 2 of the test card can be reconnected to the main housing 1 of the test card. This facilitates the replacement of the test paper and allows the main housing 1 of the test card to be reused, thereby reducing the cost of use.
