Description

Technical Field

[0001] This utility model relates to the field of reagent card technology, and in particular to an integrated card slot for a fluorescence analyzer. Background Technology

[0002] A fluorescence immunoassay analyzer is a device used to detect and analyze specific molecules in biological samples, commonly used in clinical diagnostics, drug screening, and scientific research. Currently, numerous fluorescence immunoassay analyzers are available on the market. To ensure that reagent strips can be accurately inserted into their predetermined positions and maintain a good relative position with the detection optical path and signal transmission components, a slot is usually provided within the instrument. This slot is sized to match the reagent strip; simply inserting the reagent strip into the slot completes the alignment. However, during reagent production and assembly, factors such as processing errors in the slot and assembly processes may cause the slot width to be significantly larger than the reagent strip. This can lead to the reagent strip not maintaining a stable relative position with the detection optical path and signal transmission components, ultimately affecting the accuracy and stability of the test results.

[0005] Preferably, the first abutment is an inclined surface located on one side of the slot, and the inclined surface gradually protrudes from the end near the slot entrance to the end away from the entrance.

[0006] Preferably, the width of the front section of the card slot is greater than the width of the reagent card strip, and the inclined surface is located in the middle section of the card slot.

[0007] Preferably, the card slot is provided with a first elastic part on the side of the inclined surface. The first elastic part abuts against the reagent card strip in the card slot and is used to push the reagent card strip toward the other side of the card slot.

[0008] Preferably, the first abutment is located in the middle section of one side of the slot, and the first elastic part is located in the rear section of that side.

[0009] Preferably, the rear section of the side of the slot where the first elastic part is provided has a notch, and the first elastic part is provided at the notch on the side.

[0010] Preferably, the first elastic part includes a first snap-fit ​​section and a first connecting section. The first snap-fit ​​section is located at the front end of the first connecting section, and the rear end of the first connecting section is fixedly connected to the rear end face at the notch. The first snap-fit ​​section gradually protrudes into the card slot from the end near the card slot inlet to the end away from the inlet.

[0011] Preferably, the second abutment is a second elastic part, and the surface of the second elastic part that contacts the reagent card strip gradually protrudes from the end near the card slot inlet to the end away from the inlet.

[0014] The beneficial effects of this utility model are as follows: This utility model provides an integrated card slot for a fluorescence analyzer. Compared with the prior art, this utility model has at least the following technical effects: 1. A first abutment is provided on the side of the card slot, and a second abutment is provided on the bottom or top surface of the slot to push the reagent card strip in the slot toward the aligned side. This can reduce the processing error of each component and lower the processing accuracy requirements. As long as the aligned side meets the dimensional accuracy requirements, it is sufficient to reduce production costs and ensure that the actual reagent card strip maintains a good relative position with the detection optical path and signal transmission components. 2. The first abutment is an inclined surface with gradually convex dimensions. As the reagent card strip is gradually pushed in, it will push the actual card strip toward the other side of the slot to align, thereby offsetting the processing error. 3. A first elastic part is provided on the same side of the inclined surface of the card slot. The first elastic part and the inclined surface cooperate to push the side of the reagent strip away from the inclined surface completely to the other side, so that it fits completely with the other side. This ensures that the reagent strip maintains a good relative position with the detection optical path and signal transmission components, ensuring the accuracy of identification during detection. 4. A notch is provided on the side of the first elastic part to provide sufficient movement space for the deformation of the first elastic part, that is, to ensure that the first elastic part can compress the reagent strip. 5. A second elastic part is provided on the bottom surface. This allows the reagent strip to be pushed upward during the insertion of the reagent strip, pushing it towards the limiting part and aligning it with the upper side of the card slot. This cooperates with the first pushing part to achieve alignment of the side and top surfaces, compensating for the processing errors of the bottom and side surfaces, ensuring that the reagent strip maintains a good relative position with the detection optical path and signal transmission components, and ensuring detection accuracy.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Please see Figures 1 to 2An integrated card slot for a fluorescence analyzer includes a slot body 1, in which a U-shaped card slot 2 is formed. A first abutment is provided on one side of the card slot 2 to push a reagent strip 9 towards the other side. Limiting portions 3 are respectively provided on the top surfaces of both sides of the card slot 2, with the distance between the two limiting portions 3 being less than the width of the reagent strip 9. A second abutment is provided on the bottom surface of the card slot 2 or the lower end surface of the limiting portion 3 to push the reagent strip 9 towards the limiting portion 3 or the bottom surface of the card slot 2. By providing a first abutment on the side of the card slot 2 in the slot body 1 and a second abutment on the bottom or top surface, the reagent strip 9 in the card slot 2 can be pushed towards an aligned side. This reduces processing errors of various components and lowers the requirements for processing precision. As long as the aligned side meets the required dimensional accuracy, it is sufficient, which helps reduce production costs and also ensures that the reagent strip 9 maintains a good relative position with the detection optical path and signal transmission components.

[0020] Please see Figures 1 to 2 Preferably, the first abutment is an inclined surface 4 located on one side of the card slot 2, and the inclined surface 4 gradually protrudes from the end near the entrance of the card slot 2 to the end away from the entrance. The first abutment is an inclined surface 4, and the size gradually protrudes so that as the reagent card strip 9 is gradually pushed in, it will push the actual card strip to the other side of the card slot 2 for alignment, thereby compensating for errors caused by processing.

[0021] Please see Figures 1 to 2 Preferably, the width of the front section of the slot 2 is greater than the width of the reagent strip 9, and the inclined surface 4 is located in the middle section of the slot 2. This facilitates the insertion of the reagent strip 9 into the slot 2 and guides the reagent strip 9 to the other side.

[0022] Please see Figures 1 to 2 Preferably, the slot 2 is provided with a first elastic part 5 on the side of the inclined surface 4. The first elastic part 5 abuts against the reagent strip 9 in the slot 2, and is used to push the reagent strip 9 towards the other side of the slot 2. The slot 2 is provided with a first elastic part 5 on the same side of the inclined surface 4. The first elastic part 5 and the inclined surface 4 cooperate to push the reagent strip 9 away from the inclined surface 4 completely towards the other side, so that it is completely in contact with the other side, ensuring that the reagent strip 9 maintains a good relative position with the detection optical path and signal transmission components, and ensuring the recognition accuracy during detection. The first abutting member is located in the middle section of one side of the slot 2, and the first elastic part 5 is located in the rear section of that side.

[0023] Please see Figures 1 to 2Preferably, the rear section of the side of the slot 2 of the first elastic part 5 is provided with a notch 6, and the first elastic part 5 is provided at the notch 6 on this side. Sufficient movement space is provided for the deformation of the first elastic part 5, that is, to ensure that the first elastic part 5 can compress the reagent strip 9.

[0024] Please see Figures 1 to 2 Preferably, the first elastic part 5 includes a first snap-fit ​​section and a first connecting section. The first snap-fit ​​section is located at the front end of the first connecting section, and the rear end of the first connecting section is fixedly connected to the rear end face at the notch 6. The first snap-fit ​​section gradually protrudes into the card slot 2 from the end near the entrance of the slot 2 to the end away from the entrance. The first connecting section serves to deform under force, while the first snap-fit ​​section serves to contact the reagent card strip 9. The two work together to push the reagent card strip 9 to the other side, so that the reagent card strip 9 is aligned to the side.

[0025] Please see Figures 1 to 2 Preferably, the second abutment is a second elastic part 7, and the surface of the second elastic part 7 that contacts the reagent strip 9 gradually bulges from the end near the inlet of the slot 2 to the end away from the inlet. The second elastic part 7 is provided on the bottom surface so that during the insertion of the reagent strip 9, it can push the reagent strip 9 upwards to the limiting part 3, aligning it with the upper side of the slot 2. This, in conjunction with the first abutment, achieves alignment of the side and top surfaces, offsetting processing errors on the bottom and side surfaces, ensuring that the reagent strip 9 maintains a good relative position with the detection optical path and signal transmission components, and ensuring detection accuracy.

[0026] Please see Figures 1 to 2 Preferably, the bottom surface of the card slot 2 is provided with a clearance groove 8, and the second elastic part 7 is disposed at the clearance groove 8 on the bottom surface of the card slot 2. The clearance groove 8 provides sufficient space for the movement of the second elastic part 7.

[0027] Please see Figures 1 to 2 Preferably, the second elastic part 7 includes a second spring-loaded section and a second connecting section. The second spring-loaded section is located at the front end of the second connecting section, and the rear end of the second connecting section is fixedly connected to the rear end face of the relief groove 8. The second spring-loaded section gradually protrudes into the groove 2 from the end near the inlet of the groove 2 to the end away from the inlet. The second connecting section serves to deform under force, while the second spring-loaded section serves to contact the reagent strip 9. The two work together to push the reagent strip 9 toward the limiting part 3 so that the reagent strip 9 is aligned with the limiting part 3.

[0028] Preferably, the inclined surface 4 and the first elastic part 5 can be moved to the left, and the second elastic part 7 can be moved to the top, or the shapes of the first elastic part 5 and the second elastic part 7 can be changed, and are not limited to the shapes and positions shown in the figures.

[0029] The working principle of this utility model is as follows:

[0030] Step 1: When the reagent strip 9 is inserted into the slot 2, the width of the front section of the slot 2 is larger than that of the reagent strip 9, which can ensure that the slot 2 is inserted smoothly. The middle section of the slot 2 is designed with a slope 4. As the slope 4 gradually protrudes, the width of the slot 2 will gradually decrease. When passing the slope 4, the reagent strip 9 is gradually guided to the side of the slot 2 opposite to the slope 4.

[0031] Step 2: Next, when the reagent strip 9 passes through the inclined plane 4, it will be pushed by the second elastic part 7 at the bottom of the slot 2 towards the limiting part 3 at the top of the slot 2. At this time, the top surface of the reagent strip 9 is limited to the lower end surface of the limiting part 3.

[0032] Step 3: As the reagent strip 9 moves into the slot 2, the right side of the strip is pushed by the first elastic part 5 towards the side opposite to the inclined surface 4. At this time, the left side of the reagent strip 9 is restricted to the left side of the slot 2.
