Description

Technical Field

[0001] This utility model relates to the field of fluorescence immunoassay quantitative analysis technology, and in particular to an adjustable fastening device for reagent cards. Background Technology

[0002] When performing solid-phase fluorescence detection using an automated fluorescence immunoassay analyzer, the reagent card needs to be inserted into the securing device before fluorescence detection can be performed. The secure fixation of the reagent card is a necessary prerequisite for accurate test results.

[0003] The existing reagent card fastening device is unstable when the reagent card is inserted, and it will swing from side to side. This causes the detection area in the reagent card to be misaligned with the center of the laser each time it is tested, resulting in inaccurate results from the instrument with large deviations. Even with the same reagent card, repeated tests will yield different results.

[0004] In addition, most existing fastening devices are one-piece designs, which means that the fastening device can only adapt to reagent cards of one width. When the width of the reagent card changes, the fastening device cannot adapt, which reduces the adaptability of the fastening device.

[0005] This application discloses an adjustable reagent card fastening device. The width of the fastening device is adjustable, which allows the fastening device to adapt to reagent cards of various widths and sizes, thus improving the adaptability of the fastening device. In addition, the fastening device has a relatively stable elastic fixing device, which makes the fastening device have good stability for the reagent card. Utility Model Content

[0006] To address the problems in related technologies, this application discloses an adjustable reagent card fastening device, which adopts a split design and an elastic fixing device, can adapt to reagent cards of various widths, and has a relatively stable reagent card positioning function.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] An adjustable reagent card fastening device for securing reagent cards is characterized by comprising: a carrier with a card slot for accommodating the reagent card inside; a detection port at the top of the carrier; top fixing plates on both sides of the detection port; side fixing plates on both sides of the carrier; the top fixing plates and side fixing plates being fixedly connected; and a first bottom fixing plate and a second bottom fixing plate at the bottom of the carrier, which are separately configured. Each of the first and second bottom fixing plates has a fixing hole for adjustable and fixed connection to a device. Elastic fixing devices are provided on the bottom and sides of the carrier to elastically secure the reagent card within the card slot. These elastic fixing devices secure the reagent card within the card slot enclosed by the top fixing plate, side fixing plate, first bottom fixing plate, and second bottom fixing plate, preventing the reagent card from swaying left and right. The width of the inserted reagent card can be adjusted by adjusting the distance between the first and second bottom fixing plates.

[0009] As a further aspect of this application, the side fixing plate on one side of the carrier is provided with an elastic fixing device. This structure helps to fix one side of the reagent card against the side fixing plate on the one side of the carrier, keeping the reagent card in a position parallel to the insertion direction, and avoiding deviation between the reagent card and the insertion direction due to uneven elasticity of the elastic fixing devices on both sides.

[0010] As a further embodiment of this application, the first bottom fixing plate and the second bottom fixing plate are each provided with an elastic fixing device. This structure helps to apply force evenly to the bottom of the reagent card, ensuring that the reagent card is flat against the bottom of the top fixing plate, keeping the reagent card level and preventing it from tilting.

[0011] As a further aspect of this application, the elastic fixing device includes an elastic groove with an elastic fixing plate at its center. One end of the elastic fixing plate is fixedly connected to the carrier, and the other end of the elastic fixing plate has an elastic protrusion. The elastic protrusion and the elastic fixing plate elastically limit and fix the reagent card. This structure facilitates the sliding of the reagent card on the outer surface of the elastic groove and applies a continuous elastic force to fix the reagent card, thereby ensuring its fixation.

[0012] As a further embodiment of this application, the elastic grooves on the first and second bottom fixing plates are symmetrically arranged in opposite directions. This structure provides more stable fixation for the reagent card, and the elastic resistance experienced when the reagent card is inserted and removed is the same, which is beneficial for the reagent card to slide within the slot. Furthermore, this structure allows the first bottom fixing plate to be rotated 180° to achieve the same structure as the second bottom fixing plate, saving manufacturing steps.

[0013] As a further embodiment of this application, the side fixing plate is provided with two symmetrically arranged elastic fixing devices in the horizontal direction. This structure provides more stable fixation for the reagent card and helps to apply elastic force evenly to the sides of the reagent card, preventing the reagent card from deviating from its central position due to uneven force application.

[0014] By adopting the above technical solution, the reagent card is stably fixed below the top fixing plate of the card slot using the elastic fixing devices on the bottom and sides of the carrier. The symmetrically arranged elastic fixing devices facilitate the smooth insertion and removal of the reagent card.

[0015] In summary, the beneficial effects of this application are as follows:

[0016] The first and second bottom fixing plates are adjustable, allowing for adjustable card slot width to accommodate reagent cards of various widths, thus improving the adaptability of the fastening device. In addition, symmetrical and opposite elastic fixing devices are set on the bottom and sides of the carrier, which makes the fixation of the reagent cards more stable. Attached Figure Description

[0029] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0030] like Figure 1 , Figure 2 , Figure 5 As shown, an adjustable reagent card fastening device for fixing reagent cards includes a carrier 1. The carrier 1 has a card slot 2 inside that can accommodate the reagent card. The upper part of the carrier 1 has a detection port 3. The detection port 3 has a top fixing plate 4 on both sides. The carrier 1 has a side fixing plate 5 on both sides. The top fixing plate 4 and the side fixing plate 5 are fixedly connected. The bottom of the carrier 1 includes a first bottom fixing plate 6 and a second bottom fixing plate 7. The first bottom fixing plate 6 and the second bottom fixing plate 7 are separately set. The first bottom fixing plate 6 and the second bottom fixing plate 7 are respectively provided with fixing holes 8. They are adjustablely fixed to the device through the fixing holes 8. The width of the card slot 2 formed by the bottom of the top fixing plate 4, the first bottom fixing plate 6, the second bottom fixing plate 7 and the side fixing plate 5 can be adjusted. The carrier 1 has elastic fixing devices 9 at the bottom and sides. The width of the card slot 2 can be finely adjusted through the elastic fixing devices 9 and the reagent card in the card slot 2 can be elastically fixed.

[0031] like Figure 2 As shown, the side fixing plate on one side of the carrier 1 is provided with an elastic fixing device 9, that is, only the side fixing plate 5 on the second bottom fixing plate 7 is provided with an elastic fixing device 9. When the reagent card is inserted into the card slot 2, the reagent card is elastically fixed at a position flush with the side fixing plate 5 on the first bottom fixing plate 6, that is, the side fixing plate 5 on the first bottom fixing plate 6 is used as a vertical reference surface to position and fix the reagent card.

[0032] like Figure 2 , Figure 3 As shown, the first bottom fixing plate 6 and the second bottom fixing plate 7 are respectively provided with elastic fixing devices 9. This facilitates the even application of force to elastically fix the reagent card to the bottom of the top fixing plate 4, keeping it horizontally and flatly fixed in the card slot 2. That is, the top fixing plate is used as a horizontal reference surface to position and fix the reagent card.

[0033] like Figure 1 , Figure 3 , Figure 4 As shown, the elastic fixing device 9 includes an elastic groove 91, an elastic fixing plate 92 is provided at the center of the elastic groove 91, one end of the elastic fixing plate 92 is fixedly connected to the carrier 1, and the other end of the elastic fixing plate 92 is provided with an elastic protrusion 93. The elastic protrusion 93 and the elastic fixing plate 92 elastically limit and fix the reagent card.

[0034] like Figure 3 As shown, the elastic grooves 91 on the first bottom fixing plate 6 and the second bottom fixing plate 7 are symmetrical and opposite in direction. That is, the elastic protrusions 93 on the first bottom fixing plate 6 are located at the rear end of the carrier 1, and the elastic protrusions 93 on the second bottom fixing plate 7 are located at the front end of the carrier 1. This structure provides more stable fixation for the reagent card, applies a uniform force to the bottom of the reagent card, and ensures that the force acting on the reagent card is the same when the reagent card is inserted and removed.

[0035] like Figure 4 As shown, the side fixing plate 5 on the second bottom fixing plate 7 has two symmetrically arranged elastic fixing devices 9 in the horizontal direction. This structure provides more stable fixation for the reagent card, and the force applied to the front and rear ends of the reagent card is the same and balanced when the reagent card is inserted and removed.

[0036] The implementation principle of the adjustable fastening device for reagent cards in this application embodiment is as follows: adopting a split design, the device is tunably and fixedly connected to the equipment through the fixing holes 8 on the first bottom fixing plate 6 and the second bottom fixing plate 7. The width of the card slot 2 can be adjusted to accommodate reagent cards of various widths. The reagent card is positioned with the top fixing plate and the side fixing plate as reference surfaces. The width of the card slot 2 is finely adjusted using the elastic fixing device 9 to accurately position and fix the reagent card.

[0037] Finally, it should be noted that the above disclosure is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. The scope of this application is limited only by the appended claims.
