Abstract
Description
Technical Field
[0001] This invention belongs to the field of reagent kit technology, and particularly relates to a reagent kit structure. Background Technology
[0002] In the field of in vitro diagnostics for medical devices, such as chemiluminescence immunoassay analyzers, a consumable material called a reagent kit is used. The reagent kit contains reagents, and the types of reagents vary depending on the specific test being performed.
[0003] During use, the operator must first manually place the reagent kit into the testing instrument. The instrument will then automatically draw up and add reagents as needed. This requires the reagent kit to be accurately positioned within the device; it must be securely fixed in all directions (front, back, left, right, top, bottom). The ease and security of the operator's placement of the reagent kit are closely related to its structure and usage method. A well-designed reagent kit is easier for the operator to use, requiring less skill and significantly improving the user experience. It also greatly reduces the risk of unforeseen consequences caused by improper reagent placement.
[0004] Currently, reagent kits from different manufacturers have different structures and usage methods. Some are easy to operate, while others require the operator to master certain methods to operate.
[0005] For example, in the invention patent application with publication number CN109939599A, the method of using the reagent kit is as follows: the operator first holds the reagent kit with the front lower than the back, engaging the gear at the bottom of the front of the reagent kit with the gear on the instrument, and then presses down on the rear of the reagent kit. The spring-loaded structure at the bottom of the rear of the reagent kit engages with the reagent tray, thus completing the reagent kit loading operation. If the gear at the front of the reagent kit is not properly engaged during the operation, the spring-loaded structure at the rear of the reagent kit may not be in the correct position, thus failing to achieve longitudinal positioning of the reagent kit. In this case, the position of the gear at the front of the reagent kit needs to be manually rotated, and the operation repeated. When removing the reagent kit, it is necessary to forcefully move the reagent kit towards the rear until the gear at the front disengages, and then move the reagent kit forward with the front higher than the back to disengage the spring-loaded structure at the rear of the reagent kit from the reagent tray. This operation method requires the operator to master the key points of operation, and even if the operator masters the key points, it is still not very convenient to operate.
[0006] Therefore, designing a more reasonable reagent kit structure is an urgent problem to be solved so that it can be more convenient and reliable for operators to use. Summary of the Invention
[0007] To overcome the problems existing in related technologies, this invention discloses a reagent kit structure, the specific technical solution of which is as follows:
[0008] According to a first aspect of the present invention, a reagent kit structure is provided, including a reagent tray holder, on which a pair of reagent kit positioning components are disposed, the reagent kit positioning components comprising:
[0009] The main body of the positioning block is assembled on the reagent tray holder;
[0010] Guide grooves are provided on the main body of the positioning block;
[0011] A toggle element is provided on the side surface of the positioning block body, and the end of the toggle element rotates about the positioning block body as an axis.
[0012] The reagent kit structure also includes: a reagent kit, on which a guide post is provided, the guide post being vertically embedded in a guide groove;
[0013] The angle between the actuating direction of the actuating element and the opening direction of the guide groove is an acute angle.
[0014] Optionally, an opening is provided on the top of the positioning block body, and a positioning block cover is provided at the opening.
[0015] Optionally, the toggle element includes:
[0016] A pair of torsion springs are respectively mounted on opposite surfaces of the positioning block body via fasteners. The fasteners can be screws.
[0017] Optionally, the side surface of the reagent kit is provided with an auxiliary positioning structure;
[0018] The main body of the positioning block is provided with an auxiliary positioning groove. The auxiliary positioning structure is vertically embedded in the auxiliary positioning groove, and one side surface of the auxiliary positioning structure is in contact with the other side surface of the auxiliary positioning groove.
[0019] The reagent kit structure provided by this invention can achieve at least the following beneficial effects:
[0020] First, the reagent kit is equipped with guide posts to facilitate the positioning of the reagent kit during placement. The torsion spring on the positioning block of the reagent kit will apply a forward force to the guide posts of the reagent kit. When the reagent kit slides vertically down to the bottom of the guide groove of the positioning block, the reagent kit will be immediately pushed to the corner of the guide groove by the torsion spring. This achieves both the combination of the bottom structure of the front end of the reagent kit and other components of the reagent tray, and the vertical positioning of the reagent kit.
[0021] Secondly, even if the bottom structure at the front of the reagent kit and the corresponding parts of the reagent tray are not accurately engaged during the reagent kit placement process, it will not affect the normal use of the reagent kit. This is because the longitudinal positioning of the reagent kit is still effective in this case and it will not come out of the positioning block. When the reagent tray is in operation, the bottom structure at the front of the reagent kit will automatically and accurately engage with the corresponding parts of the reagent tray.
[0022] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the scope of protection claimed by the present invention. Attached Figure Description

[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.
[0033] A preferred embodiment of the present invention provides a reagent kit structure. In related technologies, reagent kits require the operator to manually place them into the testing instrument, which then automatically draws and adds reagents as needed. This requires the reagent kit to be accurately positioned within the device, with the front, back, left, right, top, and bottom directions all securely fixed. The ease and security of the operator's placement of the reagent kit are closely related to its structure and usage method. Improper operation can lead to unpredictable consequences due to the operator's incorrect placement of the reagent kit. Therefore, the reagent kit structure provided in this embodiment allows the guide post on the reagent kit to slide into the guide groove on the reagent kit positioning block. As the reagent kit slides downwards, a torsion spring on the positioning block applies a forward force to the guide post. When the reagent kit slides vertically down to the bottom of the guide groove, it is immediately pushed by the torsion spring to the corner of the guide groove. This achieves both the integration of the reagent kit's front bottom structure with other components of the reagent tray and the longitudinal positioning of the reagent kit.
[0034] Figure 1 An assembly diagram of a reagent kit structure provided by a preferred embodiment is shown as an example. Figure 1 As can be seen, the reagent kit 100 is provided with a guide post 101 to facilitate the positioning of the reagent kit 100 during placement. The reagent tray 300 is equipped with a reagent kit positioning block 200, which is provided with a guide groove 2011 and a torsion spring 203. During placement, the guide post 101 on the reagent kit 100 is slid into the guide groove 2011 on the positioning block body 201 of the reagent kit 200. As the reagent kit 100 slides downward, the torsion spring 203 on the positioning block 200 applies a forward force to the guide post 101 on the reagent kit 100. When the reagent kit 100 slides vertically downward to the bottom of the guide groove 2011 on the positioning block body 201, the reagent kit 100 will be immediately pushed by the torsion spring 203 to the corner of the guide groove 2011. This achieves both the integration of the front bottom structure of the reagent kit with other components of the reagent tray and the vertical positioning of the reagent kit.
[0035] Even if the structure at the bottom front of the reagent kit and the corresponding parts of the reagent tray do not fit together precisely during the reagent kit placement process, it will not affect the normal use of the reagent kit. This is because the longitudinal positioning of the reagent kit is still effective in this case and it will not fall out of the positioning block. When the reagent tray starts to rotate, the structure at the bottom front of the reagent kit will automatically and accurately fit together with the corresponding parts of the reagent tray. This all depends on the ingenuity of the structural design.
[0036] To remove the kit, simply apply a small force to the back of the kit and then lift it upwards; the kit will then be removed from the positioning block.
[0037] Preferably, the angle between the toggle direction of the end of the torsion spring 203, which is the actuating element, and the opening direction of the guide groove is an acute angle. When the reagent kit slides downward, the end of the torsion spring 203 is squeezed and deformed. In order to restore the elastic deformation, a reverse force is applied to the reagent kit. The direction of this force is an acute angle with the extension direction of the guide groove 2011. That is, the reagent kit always receives a pushing force in the direction of the guide groove 2011. The reagent kit 100 will be immediately pushed to the corner of the guide groove 2011 by the torsion spring 203.
[0038] Preferably, the upper part of the positioning block body 201 is provided with an opening, and a positioning block cover 202 is provided at the opening.
[0039] Preferably, the side surface of the reagent kit is provided with an auxiliary positioning structure 102; the main body 201 of the positioning block is provided with an auxiliary positioning groove 2012, the auxiliary positioning structure 102 is vertically embedded in the auxiliary positioning groove 2012, and one side surface of the auxiliary positioning structure 102 is in contact with one side surface of the auxiliary positioning groove 2012.

This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the appended claims.
