Description

Technical Field

[0001] The utility model relates to the technical field of in vitro diagnostic reagent packaging, and more specifically to a special card tray for micro-column gel immunoassay cards. Background Art

[0002] Microcolumn gel immunoassay technology is a combination of biochemical gel filtration technology and immunological antigen-antibody reaction. The size of the gel gap is controlled by the size of the gel particles, so that only free RBCs can pass through the gap, thereby separating free RBCs from aggregated RBCs. In addition, anti-human globulin and various blood type antibodies have been added to the gel, which simplifies the operation process. You only need to add the sample and centrifuge it (incubate).

[0003] The microcolumn gel in the microcolumn gel immunoassay technology is filled in a microcolumn gel card. The microcolumn gel card is a rectangle that is wide at the top and narrow at the bottom. The bottom is only 1mm wide, the top is about 9mm wide, and there are six microcolumn holes on the top, which makes it difficult to stand upright. Therefore, in the prior art, in order to facilitate the overall transportation or movement of multiple microcolumn gel immunoassay cards, multiple microcolumn gel immunoassay cards 100 are generally inserted into multiple placement holes 2001 of a card holder 200, such as Figure 1 and Figure 2 shown.

[0004] However, the existing card tray 200 is made of polypropylene (PP) material, which is soft and easy to deform. If it is stacked, it is easy to collapse, and it can only be placed in a single row, resulting in low transportation space utilization and high transportation costs. In addition, the gap between the placement holes 2001 is large. When the micro-column gel immunoassay card 100 is placed in the placement hole 2001 on the card tray 200, there is a certain amount of shaking on the left and right, which causes the card tray 200 and the micro-column gel immunoassay card 100 to collide easily during transportation, thereby affecting the quality of the card. In addition, due to the micro-column gel immunoassay The test card 100 is easily shaken when placed in the card tray 200, resulting in an unstable position of the card, which in turn causes the existing card tray 200 to be unable to be used with the fully automatic blood analyzer. The doctor needs to manually take out multiple microcolumn gel immunoassay cards 100 from the card tray 200 one by one, and then put them one by one into the card tray on the fully automatic blood type detector, thereby wasting a lot of detection time and ultimately reducing the detection efficiency. Moreover, after the microcolumn gel immunoassay card 100 is placed on the analyzer, the card tray 200 has no practical use, resulting in waste.

[0005] Therefore, how to provide a special card tray for microcolumn gel immunoassay detection card that can stably support the microcolumn gel immunoassay detection card, can be directly placed in a fully automatic blood analyzer without the need to manually place the card in the analyzer, and can save space, effectively reduce the outer packaging size, and reduce transportation costs is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0010] Through the above technical scheme, it can be known that compared with the prior art, the utility model discloses a special card tray for micro-column gel immunoassay card. After the micro-column gel immunoassay card is inserted into the card position placement hole, the abutting side plates on both sides of the micro-column gel immunoassay card can abut against the hole walls on the two opposite sides of the card position placement hole, and then the hole walls on the left and right sides limit the micro-column gel immunoassay card to the left and right, and the two side walls of the micro-column gel immunoassay card are respectively limited and inserted in two relatively arranged limiting slots, and then the limiting slots on the front and back sides limit the micro-column gel immunoassay card to the front and back, so that the micro-column gel immunoassay card does not shake after being placed on the card tray body, solving the problem of the quality of the card affected by the collision between the card tray and the card during transportation. In addition, the card tray is fully compatible with the card tray for the fully automatic blood analyzer, and does not need to be replaced. The micro-column gel immunoassay card can be directly placed in the fully automatic blood analyzer together with the card tray body, and there is no need to manually put the cards one by one into the card tray in the analyzer, which greatly saves the time for placing the card and improves the detection efficiency.

In addition, the tray bodies stacked up and down can be connected through the microcolumn gel immunoassay card, which also improves the difficulty of shaking in the left and right directions after the adjacent tray bodies are stacked.

[0015] Furthermore, two staggered holes are provided on two opposite front and rear side walls of each of the card holder bodies, and a first support plate is fixed on the front and rear sides of the bottom end of each of the card holder bodies. The first support plate on the upper card holder body is inserted into the staggered holes on the lower card holder body, so that the two card holder bodies in adjacent layers are staggered and stacked.

[0016] The beneficial effect of adopting the above technical solution is that multiple card tray bodies can be stacked up and down in an alternating manner, and every two card tray bodies can save 30% of the space. The more stacked card trays are, the higher the space saving ratio is. Therefore, the outer packaging size can be reduced, and the transportation cost and packaging cost can be reduced.

[0018] The beneficial effect of adopting the above technical solution is that when stacking, the second support plate on the upper card tray body is inserted into the staggered holes on the lower card tray body, which not only enables the upper and lower staggered stacking to improve space utilization, but also enables the stability of the card trays when stacked, making it difficult for the card trays to become loose, thereby ensuring that the stacked card trays can be normally packaged and transported as a whole.

[0019] Furthermore, the staggered holes are in the shape of expanded strip holes with the upper hole opening being larger than the lower hole opening.

[0020] The beneficial effect of adopting the above technical solution is that the second support plate can be quickly inserted into the staggered holes.

[0021] Furthermore, a second support plate is fixed at the front and back on the other side of the bottom end of each of the card holder bodies, and the second support plate includes: a third support plate and a fourth support plate, the top of the third support plate is integrally connected to the side wall of the card holder body, the top of the fourth support plate is fixedly connected to the bottom end surface of the card holder body, one side of the third support plate is perpendicular to and integrally connected to one side of the fourth support plate, and the first support plate, the second support plate, the third support plate and the fourth support plate on the upper card holder body are all clamped on the outer side surface of the card holder body of the lower layer.
