[0002] A fluorescence quantitative detection card is a tool for biological sample detection. This detection card quantitatively analyzes the concentration of target molecules in the sample through the fluorescence principle. When in use, sampling is first required, then a suitable fluorescence labeling reagent is selected, the sample and the reagent are mixed to form a mixed solution, the mixed solution is dropped on the sample adding hole of the detection card, and then after waiting for a period of time, the detection card is inserted into the instrument, and the instrument can detect the detection card.
[0003] When a common fluorescence quantitative detection card is in use, the sample and the reagent are mixed to form a mixed solution, the mixed solution is dropped on the sample adding hole of the detection card, and then after waiting for a period of time, the detection card is inserted into the instrument, and the instrument can detect the detection card. However, after the mixed solution is dropped on the detection card, it is necessary to wait for a period of time. During the long waiting time, the detection card is directly exposed, making the sample adding hole of the detection card vulnerable to contamination. After being contaminated, it will affect the subsequent detection accuracy. Therefore, this application provides a fluorescence quantitative detection card for improving detection accuracy to meet the requirements. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a fluorescence quantitative detection card for improving detection accuracy to solve the technical problem that the detection card is directly exposed, making the sample adding hole vulnerable to contamination, and after being contaminated, it will affect the subsequent detection accuracy.
[0005] To solve the above technical problem, the utility model provides the following technical solutions:
[0006] A fluorescence quantitative detection card for improving detection accuracy, including a detection card body. A transparent shim is attached to the top of the detection card body. A U-shaped ring is fixed to the bottom of the transparent shim. The detection card body is located inside the U-shaped ring. A U-shaped strip is fixed to the inner wall of the U-shaped ring. A guiding groove is formed on the side of the detection card. The U-shaped strip is slidably connected in the guiding groove. A clamping member is arranged on the inner wall of the U-shaped strip for positioning the transparent shim and the U-shaped ring. A push block is fixed to the transparent shim, and the side surface of the push block is flush with the side surface of the transparent shim.
[0007] Preferably, limiting blocks are fixed to both opposite sides of the detection card body. A sliding groove is formed at the bottom of the U-shaped ring, and the inner wall of the sliding groove is slidably connected to the top of the limiting block.
[0008] Preferably, anti-slip blocks are fixed to both opposite sides of the U-shaped ring, and the anti-slip blocks cover the side surfaces of the limiting blocks.
[0009] Preferably, the anti-slip block includes a connecting portion, a bending portion, and a shielding portion that are connected in sequence. The connecting portion is fixed to the side surface of the U-shaped ring, and the shielding portion shields the side surface of the limiting block.
[0010] Preferably, vertical grooves are formed on the side surfaces of the connecting portion, the bending portion, and the shielding portion.
[0011] Preferably, a notch is formed on one side of the U-shaped ring away from the push block.
[0012] Preferably, the clamping member includes a square groove formed on the inner wall of the U-shaped strip. A positioning ring and a rubber disc are respectively fixed on the inner wall of the square groove. A clamping ball is fixed on the side surface of the rubber disc. A clamping groove is formed on the side surface of the inner wall of the guiding groove.

[0013] Preferably, a rubber block is fixed on one side of the inner wall of the square groove away from the clamping groove. The side of the rubber block close to the rubber disc is a curved surface, and a cavity is provided inside the rubber block.
[0014] Compared with the prior art, the present utility model has at least the following beneficial effects:
[0015] In the above solution, through the setting of the transparent shim, move the transparent shim so that the transparent shim no longer shields the sample addition hole on the test card body. Drop the mixed liquid into the sample addition hole. After the operation is completed, move the transparent shim in the reverse direction so that the transparent shim shields the sample addition hole. Then, wait for a period of time and then insert the test card body into the instrument for detection. By shielding the test card body with the transparent shim, it is possible to prevent the sample addition hole of the test card body from being contaminated, thereby improving the subsequent detection accuracy.
[0016] Through the setting of the anti-slip block, pinch the anti-slip block to move the U-shaped ring, so that the U-shaped ring drives the transparent shim to move. Through the design of the anti-slip block, the friction between the finger and the U-shaped ring is increased to prevent slipping when moving the U-shaped ring.

[0031] As Figures 1 - 6 shown, an embodiment of the present utility model provides a fluorescence quantitative detection card for improving detection accuracy, which includes a detection card body 1. A transparent shim 2 is attached to the top of the detection card body 1. The transparent shim 2 is an acrylic board. When the transparent shim 2 covers the sample addition hole and the observation hole of the detection card body 1, the states of the sample addition hole and the observation hole on the detection card body 1 can be observed without opening the transparent shim 2. A U-shaped ring 3 is fixed to the bottom of the transparent shim 2. The detection card body 1 is located inside the U-shaped ring 3. A U-shaped strip 4 is fixed to the inner wall of the U-shaped ring 3. A guiding groove 5 is provided on the side of the detection card. The U-shaped strip 4 is slidably connected in the guiding groove 5. The cooperation between the U-shaped strip 4 and the guiding groove 5 realizes the guiding during the movement of the U-shaped ring 3 and the transparent shim 2. A clamping member 9 is provided on the inner wall of the U-shaped strip 4. The clamping member 9 is used to position the transparent shim 2 and the U-shaped ring 3. A push block 7 is fixed to the transparent shim 2. The side of the push block 7 is flush with the side of the transparent shim 2.
[0032] As Figure 4 shown, in this embodiment, limiting blocks 10 are fixed to both opposite sides of the detection card body 1. A sliding groove 11 is formed at the bottom of the U-shaped ring 3. The inner wall of the sliding groove 11 is slidably connected to the top of the limiting block 10. The sliding groove 11 provides space for the movement of the U-shaped ring 3. The limiting block 10 is used to prevent the U-shaped ring 3 from separating from the detection card body 1, thereby preventing the transparent shim 2 from separating from the detection card body 1.
[0033] As Figure 1 and Figure 2As shown, in this embodiment, anti-slip blocks 8 are fixed on both opposite sides of the U-shaped ring 3. The anti-slip blocks 8 cover the sides of the limiting blocks 10. The anti-slip blocks 8 are used to increase the friction between the U-shaped ring 3 and the fingers, prevent slipping when moving the U-shaped ring 3, and at the same time, the anti-slip blocks 8 cover the sides of the limiting blocks 10 to prevent pinching the limiting blocks 10 while pinching the anti-slip blocks 8, which affects the movement of the U-shaped ring 3.
[0034] As Figure 2 shown, in this embodiment, the anti-slip block 8 includes a connecting portion 81, a bending portion 82, and a shielding portion 83 that are connected in sequence. The connecting portion 81 is fixed to the side of the U-shaped ring 3, and the shielding portion 83 covers the side of the limiting block 10. The connecting portion 81 is used for connecting the bending portion 82 and the shielding portion 83 to the U-shaped ring 3. The shielding portion 83 covers the side of the limiting block 10 to prevent pinching the limiting block 10 while pinching the anti-slip block 8 to move the U-shaped ring 3, which affects the movement of the U-shaped ring 3.
[0035] As Figure 2 shown, in this embodiment, vertical grooves 84 are provided on the sides of the connecting portion 81, the bending portion 82, and the shielding portion 83. The vertical grooves 84 are used to increase the anti-slip ability of the anti-slip block 8 and further prevent slipping when pinching and moving the U-shaped ring 3.
[0036] As Figure 1 shown, in this embodiment, a notch 6 is provided on the side of the U-shaped ring 3 away from the push block 7. When inserting the detection card body 1 into the card insertion hole of the instrument, the detection card body 1 can be pushed with fingers from the notch 6 position, so as to facilitate inserting the detection card body 1 into the card insertion hole.
[0037] As Figure 4 shown, in this embodiment, the card member 9 includes a square groove 92 provided on the inner wall of the U-shaped strip 4. A positioning ring 96 and a rubber disc 93 are respectively fixed on the inner wall of the square groove 92. A card ball 91 is fixed on the side of the rubber disc 93. A card slot 97 is provided on the side of the inner wall of the guiding groove 5. The card ball 91 fits with the inner wall of the card slot 97, and the surface of the card ball 91 fits with the inner wall of the positioning ring 96. The card ball 91 is a sphere. The card ball 91 is stuck in the card slot 97 under the elastic force of the rubber disc 93, so as to realize the positioning of the transparent shim 2. The positioning ring 96 is used to prevent the card ball 91 from shifting under the friction force between the card ball 91 and the inner wall of the guiding groove 5 when the U-shaped strip 4 moves, so as to prevent the card ball 91 from pulling on the rubber disc 93.
[0038] As Figure 4 shown, in this embodiment, a rubber block 94 is fixed on the side of the inner wall of the square groove 92 away from the card slot 97. The side of the rubber block 94 close to the rubber disc 93 is a curved surface, and a cavity 95 is provided inside the rubber block 94. The cooperation of the rubber block 94 and the cavity 95 is used to improve the elastic force of the rubber disc 93, so that the card ball 91 is more stably and reliably stuck in the card slot 97, thereby realizing the stable positioning of the transparent shim 2.
[0039] Working principle: When the mixed liquid needs to be dropped on the sample adding hole on the detection card body 1, hold the position of the anti-sliding block 8 with one hand, hold the end of the detection card body 1 with the other hand, move the anti-sliding block 8, so that the anti-sliding block 8 drives the transparent baffle 2 to move through the U-shaped ring 3, so that the transparent baffle 2 no longer blocks the sample adding hole on the detection card body 1, drop the mixed liquid into the sample adding hole, and then move the transparent baffle 2 in the reverse direction after the operation is completed, so that the transparent baffle 2 blocks the sample adding hole, and then wait for a period of time and then insert the detection card body 1 into the instrument for detection;
[0040] When the U-shaped ring 3 moves, it drives the U-shaped strip 4 to move along the inner wall of the guide groove 5. At this time, the curved surface of the inner wall of the card slot 97 squeezes the ball 91, so that the ball 91 moves and squeezes the rubber disc 93, so that the rubber disc 93 deforms and squeezes the rubber block 94, and the rubber block 94 deforms synchronously. The U-shaped strip 4 drives the ball 91 to move and separate from the card slot 97, releasing the positioning state of the transparent baffle 2. When the transparent baffle 2 is moved in the reverse direction, the U-shaped ring 3 drives the U-shaped strip 4 to move reversely along the inner wall of the guide groove 5. When the side surface of the inner wall of the U-shaped ring 3 fits with the end of the detection card body 1, the ball 91 is aligned with the card slot 97. At this time, the ball 91 is stuck in the card slot 97 under the elastic force of the rubber disc 93 and the rubber block 94, realizing the positioning of the U-shaped strip 4, and thus realizing the positioning of the transparent baffle 2 through the U-shaped ring 3, preventing the transparent baffle 2 from moving randomly and affecting the protection of the sample adding hole on the detection card body 1;
[0041] When inserting the detection card body 1 into the instrument for detection, press the position corresponding to the notch 6 of the detection card body 1 with your finger, and insert the detection card body 1 into the instrument. At this time, the position of the card insertion hole of the instrument corresponds to the side surface of the transparent baffle 2 and the position of the push block 7, and the push block 7 prevents the transparent baffle 2 from entering the card insertion hole. When the detection card body 1 is inserted into the instrument, the detection card body 1 moves along the inner walls of the U-shaped strip 4 and the U-shaped ring 3, so that the detection card body 1 is stably inserted into the card insertion hole of the instrument.
[0042] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, and those skilled in the art can fully understand the present utility model without the description of these details.
[0043] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
