[0032] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0033] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this utility model, the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] like Figures 1-7 As shown, this utility model provides a disposable reagent card holder, comprising:

[0035] The box body 1 is provided with a card outlet 6 on each side near the bottom, and a plurality of reagent cards 2 are stacked in the box body 1; specifically, the box body 1 is a cuboid, and is preferably made of medical-grade plastic, which has good chemical stability and biocompatibility, and can effectively protect the reagent cards 2 from the external environment. The card outlets 6 are symmetrically arranged on the two sides of the box body 1 near the bottom, and the shape of the card outlet 6 is matched with the shape of the reagent card 2, and the size is slightly larger than that of the reagent card 2, so that the push card mechanism on the detection equipment can be inserted into one of the card outlets 6, and then the reagent card 2 can be pushed out from the other card outlet 6. The edges of the card outlet 6 are smoothly treated to avoid scratching and damaging the reagent card 2 when it is pushed out

[0036] The first magnetic part 4 is arranged on one side of the box body 1 with a card outlet 6; specifically, the first magnetic part 4 can be a permanent magnet, which is firmly pasted in the middle position of one side of the box body 1 by glue. The magnetic strength of the first magnetic part 4 is reasonably selected to ensure that sufficient adsorption force is generated with the second magnetic part 5, and the performance of the reagent card 2 is not affected due to the excessive magnetic strength;

[0037] The second magnetic part 5 is arranged on the detection equipment and is located on the same side as the push card mechanism. The second magnetic part 5 is magnetically connected with the first magnetic part 4; specifically, the second magnetic part 5 is installed on the detection equipment at a position on the same side as the push card mechanism. The second magnetic part 5 is also a permanent magnet, and its shape and size are matched with those of the first magnetic part 4. When the box body 1 is installed on the detection equipment, the first magnetic part 4 and the second magnetic part 5 are close to each other and are tightly connected by magnetic attraction, thereby realizing stable fixation of the box body 1 on the detection equipment. This magnetic connection method can effectively avoid the instability caused by problems such as bullet deformation, so that the box body 1 will not move forward and backward, ensuring that the reagent cards 2 will not freely slide out of the card outlets 6, and also ensuring that the push card mechanism can normally and stably push the reagent cards 2 out of the reagent card box, improving the accuracy and convenience of the detection operation.

[0038] In another technical solution, a spring 3 is further included, the upper end of which is fixedly connected with the top of the inner side of the box body 1, and the lower end of which is in abutment with the reagent card 2 located at the uppermost layer, and the spring 3 is always in a compressed state before the reagent card 2 at the uppermost layer is pushed out; specifically, the spring 3 is made of medical-grade stainless steel material, has good corrosion resistance and elastic performance, and can work stably for a long time in the use environment of medical instruments, the upper end of the spring 3 is fixedly connected with the top of the inner side of the box body 1 by welding, so as to ensure the firmness of the connection and prevent falling off during use, the lower end of the spring 3 is in abutment with the reagent card 2 located at the uppermost layer, and in the initial state, i.e., before any reagent card 2 is pushed out, the spring 3 is in a compressed state and accumulates elastic potential energy, when the push card mechanism pushes the reagent card 2 at the lower layer out of the card outlet 6, the force balance maintained by the lower reagent card 2 is broken. At this time, the spring 3 releases the elastic potential energy by virtue of its own elastic restoring force, applies a pushing force downward, stably pushes the reagent card 2 at the upper layer downward, and makes it fall into the position originally occupied by the reagent card 2 at the lower layer, so as to ensure that the reagent card 2 is always in a position that can be pushed out by the push card mechanism.

[0039] In another technical solution, a groove 10 is recessed in the side surface of the reagent card 2; specifically, the shell of the reagent card 2 is made of hard medical plastic, and the groove 10 is recessed in the side surface along the length direction, the shape of the groove 10 is rectangular, and the depth and width are accurately designed, so as to ensure good cooperation with the anti-reagent card sliding-out structure and not to affect the overall strength and detection performance of the reagent card 2.

[0040] The anti-reagent card sliding-out structure further includes:

[0041] A connecting part 12, one end of which is fixedly connected with the inner side wall of the box body 1; specifically, the connecting part 12 is made of medical-grade elastic plastic material, has good flexibility and fatigue resistance. One end of the connecting part 12 is integrally formed with the inner side wall of the box body 1 by injection molding, so as to ensure the firmness and stability of the connection, and make the connecting part 12 reliably fixed on the box body 1;

[0042] A free end boss 13 is arranged at the other end of the connecting part 12, the free end boss 13 has elasticity, and the free end of the free end boss 13 is clamped on the groove 10. Specifically, the free end boss 13 is arranged at the other end of the connecting part 12, is also made of medical-grade elastic plastic, has good elastic deformation capacity, and has a semispherical shape. The size of the free end of the free end boss 13 is matched with the groove 10 on the side of the reagent card 2. After the reagent card 2 is loaded into the box body 1, the free end of the free end boss 13 is slightly deformed by its own elasticity, is smoothly clamped on the groove 10, and forms an effective limiting structure.

[0043] In the above technical solution, when the push-clamp mechanism pushes the reagent card 2 to be pushed out from the card outlet 6, the free end boss 13 is elastically deformed under the pushing force of the reagent card 2, so that the reagent card 2 can smoothly pass through. In the non-push-clamp state, the free end boss 13 tightly clamps the groove 10, effectively prevents the reagent card 2 from freely sliding out of the card outlet 6, solves the problem that the reagent card 2 is easily pushed out in the traditional reagent card box. Since the free end boss 13 has elasticity, when the spring 3 pushes the upper reagent card 2 downward, the free end boss 13 can flexibly cooperate with the groove 10 of the reagent card 2, which does not hinder the falling of the reagent card 2, and can timely clamp the reagent card 2 that has fallen into place, so that the reagent card 2 is always in a stable placement state, further improves the reliability and stability of the use of the disposable reagent card box, and ensures that the detection operation can be smoothly and accurately performed.

[0044] In another aspect, the free end boss 13 has a trapezoidal cross section, and the slope of the trapezoidal cross section is directed towards the direction in which the reagent card 2 is pushed out; specifically, the free end boss 13 has a trapezoidal cross section, and the shape of the trapezoidal cross section is precisely designed and optimized to ensure structural strength while fully exerting the elastic limiting function. The slope of the free end boss 13 is directed towards the direction in which the reagent card 2 is pushed out. When the reagent card 2 is pushed out by the card pushing mechanism, the reagent card 2 comes into contact with the slope of the free end boss 13. The slope ensures that the reagent card 2 can be more smoothly pushed to cause elastic deformation of the free end boss 13 by using the guiding effect of the slope. When the card pushing mechanism applies a pushing force to the reagent card 2, the groove 10 on the side of the reagent card 2 comes into contact with the free end boss 13. As the pushing force increases, the free end boss 13 is stressed on the slope and elastically deformed in a direction away from the reagent card 2, so that the reagent card 2 can be smoothly passed through, reducing the frictional resistance between the two and avoiding the phenomenon of jamming, thereby ensuring the smoothness of the process of pushing out the reagent card 2. In a non-pushing state, the free end boss 13 tightly clamps the groove 10 on the side of the reagent card 2 by virtue of its elastic restoring force. Due to the structural characteristics of the trapezoidal cross section, the vertical plane portion of the trapezoidal cross section can provide a larger contact area and reliable limiting force, effectively preventing the reagent card 2 from freely sliding out of the card outlet 6.

[0045] In another aspect, the groove 10 is a slot body extending longitudinally along the side of the reagent card 2, and the depth of the groove 10 gradually increases from the front end to the rear end. The front end is the starting end when the reagent card 2 is pushed out, and the rear end is the end opposite to the front end. Specifically, the groove 10 is a slot body extending longitudinally along the side of the reagent card 2, and the shape of the groove 10 is regular. The design of the gradually increasing depth of the groove 10 is based on the mechanical requirements during the process of pushing out the reagent card 2. In a non-pushing state, the free end boss 13 tightly clamps the groove 10 by virtue of its elastic restoring force. When the reagent card 2 is pushed out by the card pushing mechanism, the front end of the reagent card 2 first comes into contact with the free end boss 13. At this time, the front end of the groove 10 is shallow, and the free end boss 13 is clamped into the groove 10 at a shallow depth. Under the action of a smaller pushing force, the free end boss 13 can be elastically deformed, so that the reagent card 2 can be easily moved, reducing the initial pushing resistance and the load of the card pushing mechanism. As the reagent card 2 is continuously pushed out, the part of the reagent card 2 in contact with the free end boss 13 gradually moves to a region with a deeper depth of the groove 10. Although the depth of the free end boss 13 clamped into the groove 10 increases at this time, the reagent card 2 has already obtained a certain initial speed, and the card pushing mechanism continuously applies a pushing force, so that the free end boss 13 can be smoothly pushed to be further elastically deformed, thereby ensuring the complete pushing out of the reagent card 2.

[0046] In another technical solution, a groove is recessed on the outer side of the box body 1, and a two-dimensional code label 9 is attached in the groove. The two-dimensional code label 9 is used to identify specific reagent item information. Specifically, the two-dimensional code label 9 is made of special materials that are waterproof, scratch-resistant, and resistant to chemical corrosion to adapt to the use environment in the field of medical instrument detection reagents. The two-dimensional code label 9 is pasted in the groove by using special adhesive. During the pasting process, the two-dimensional code label 9 is tightly attached to the bottom surface of the groove without air bubbles or wrinkles, ensuring the accuracy of code scanning and identification. The two-dimensional code label 9 stores specific reagent item information, including but not limited to reagent name, detection principle, sample type, expiration date, batch number, and other detailed content. During use, when the operator needs to obtain the reagent item information in the reagent card box, the two-dimensional code label 9 on the outer side of the box body 1 can be scanned by a code scanning device. After the code scanning device reads the information in the two-dimensional code label 9, the data is transmitted to the control system of the detection equipment or the external management system. The system analyzes and displays the information, making it easy for the operator to quickly and accurately understand the related information of the reagent card 2, avoiding detection errors caused by manual recording or identification errors. At the same time, the existence of the two-dimensional code label 9 also facilitates the information management and traceability of the reagent card 2 during storage, transportation, and use of the reagent card box, improving the standardization and efficiency of detection work and further ensuring the accuracy and reliability of the detection results.

[0047] In another technical solution, the material of the box body 1 is transparent. Specifically, the box body 1 is made of medical-grade polycarbonate (PC) transparent material, which has good biocompatibility, chemical stability, and mechanical strength, and meets the production standards of medical devices. The transparent material is processed into the box body 1 by injection molding process. The formed box body 1 has high light transmittance and can clearly show the internal condition, making it easy for the operator to directly observe the remaining number of the multiple reagent cards 2 stacked vertically in the box body 1 without opening the reagent card box. This can help the operator determine whether to replace a new reagent card box in time, avoiding interruption of the detection process due to depletion of the reagent card 2, and improving the continuity of the detection work.

[0048] In another technical solution, a tenon 7 is protruded on the contact surface of the first magnetic part 4, and a mortise 8 matching the tenon 7 is recessed on the contact surface of the second magnetic part 5; specifically, the tenon 7 is protruded on the contact surface of the first magnetic part 4 through a precise machining process, the material of the tenon 7 is consistent with the first magnetic part 4, the stability and reliability of the overall structure are ensured, the tenon 7 can be rectangular columnar or cross-shaped, and the height, width and length thereof are accurately designed, which can provide sufficient connection strength and will not affect the magnetic performance of the first magnetic part 4 due to the excessively large size, the mortise 8 matching the tenon 7 is recessed on the contact surface of the second magnetic part 5 by the same method, the shape and size of the mortise 8 strictly correspond to the tenon 7, the depth of the mortise 8 is slightly greater than the height of the tenon 7, the tenon 7 can be completely embedded in the mortise 8, the tenon 7 can be accurately inserted into the mortise 8 as the first magnetic part 4 approaches the second magnetic part 5, the mechanical connection of the mortise and tenon structure further enhances the connection stability between the reagent card box and the detection equipment, and the combination of the magnetic connection and the mortise and tenon structure not only solves the problem of unstable fixation caused by the deformation of the sheet, but also effectively prevents the reagent card box from rotating or deviating on the detection equipment.

[0049] In another technical solution, a buffer pad 11 is fixed to the lower end of the spring 3, the buffer pad 11 is laid on the top surface of the uppermost reagent card 2, and an anti-skid pattern is arranged on the bottom surface of the buffer pad 11; specifically, the buffer pad 11 is made of medical silica gel material, which can effectively buffer external force impact, the buffer pad 11 can be in a circular sheet structure, and the diameter thereof is slightly smaller than the size of the top surface of the reagent card 2, so as to be completely laid on the top surface of the uppermost reagent card 2, and a regular anti-skid pattern is arranged on the bottom surface of the buffer pad 11 in contact with the reagent card 2, the anti-skid pattern is designed in a strip pattern with concave-convex intervals, and the depth and width of the pattern are accurately calculated, which can provide sufficient friction to prevent the buffer pad 11 from sliding on the reagent card 2 and will not cause indentation or damage to the surface of the reagent card 2.
