Description

Kit structure

Technical Field

The utility model belongs to the technical field of kits, and particularly relates to a kit structure.

Background

In the field of in vitro diagnostics of medical devices, such as in chemiluminescent immunoassay analyzer devices, a consumable material, namely a kit, is used. The reagent box is used for containing reagents, and the types of the reagents in the reagent box are different according to different detection items.

When the kit is used, an operator is required to manually place the kit in a detection instrument, and then the instrument can automatically absorb and add reagents according to the requirement. This requires that the cartridge must be accurately positioned in the apparatus and that the cartridge must be held securely in front, back, left, right and up and down orientations. Whether the operator places the reagent kit conveniently and whether the placed reagent kit is firm or not is closely related to the structure and the using method of the reagent kit. A reagent box that structural design is reasonable, the operator can get on hand more easily, and is not high to the manipulation requirement, and this operation that can promote the operator greatly experiences, can be at to a great extent again simultaneously, avoided the instrument because the operator places the reagent box not in place, and the unpredictable consequence that causes.

In the prior art, the structures and the use methods of kits of different manufacturers are different, some kits are easy to operate, and some kits can be operated only by an operator needing to master a certain method.

For example, utility model patent application with publication number CN109939599A, kit application method does, the operator at first holds the high posture in low back before with the kit, with the gear of kit front end bottom and the gear meshing good back on the instrument, just can press down the rear end of kit, establish the shell fragment structure card of kit rear end bottom at the structure of reagent dish seat, just calculate to accomplish the kit and load the operation, if in operation process, the gear of kit front end does not have the meshing good, just can lead to the unable card in the exact position of shell fragment structure card of kit rear end, thereby can not realize the longitudinal positioning of kit, at this moment, need the position of rotatory kit front end gear by hand, operate once more. When the reagent box is taken out, the reagent box needs to be moved towards the rear end by force, after the gear at the front end is disengaged, the posture that the front end of the reagent box is high and the rear end of the reagent box is low is moved forwards, and the elastic sheet structure at the rear end of the reagent box is disengaged from the reagent plate seat. This operation mode requires the operator to master the operation key points, which is still inconvenient even if the operator masters the operation key points.

Based on this, it is a problem to be solved urgently to design a more reasonable kit structure, so that it is more convenient and reliable for the operator to use.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the utility model, as detailed in the appended claims.

The preferred embodiment of the present invention provides a kit structure. In the related art, the reagent kit is used by an operator manually placing the reagent kit in a detection instrument, and then the instrument automatically absorbs and adds the reagent according to the requirement. This requires that the cartridge must be accurately positioned in the apparatus and that the cartridge must be held securely in front, back, left, right and up and down orientations. Whether an operator places the reagent kit conveniently or not and whether the placed reagent kit is firm or not are closely related to the structure and the using method of the reagent kit, and unexpected consequences are caused due to the fact that the operator does not place the reagent kit on the instrument due to improper operation. Based on this, according to the reagent box structure provided by the technical scheme in the embodiment, the guide post on the reagent box slides into the guide groove on the reagent box positioning block, the torsion spring on the reagent box positioning block can apply forward force to the reagent box guide post when the reagent box slides downwards, and when the reagent box vertically slides downwards to the lower part of the positioning block guide groove, the reagent box can be immediately pushed to the corner of the guide groove by the torsion spring, so that the combination of the bottom structure at the front end of the reagent box and other parts of the reagent tray is realized, and the longitudinal positioning of the reagent box is also realized.

Fig. 1 schematically shows an assembly view of a cartridge structure provided by a preferred embodiment. As can be seen from fig. 1, the guide post 101 is arranged on the reagent kit 100, which facilitates positioning of the reagent kit 100 when placed, the reagent kit positioning block 200 is arranged on the reagent kit tray base 300, the guide groove 2011 and the torsion spring 203 are arranged on the reagent kit positioning block 200, when placed, the guide post 101 on the reagent kit 100 slides into the guide groove 2011 on the positioning block main body 201 of the reagent kit 200, when the reagent kit 100 slides downwards, the torsion spring 203 on the reagent kit positioning block 200 applies a forward force to the guide post 101 on the reagent kit 100, and when the reagent kit 100 vertically slides downwards to the bottom of the guide groove 2011 of the positioning block main body 201, the reagent kit 100 is immediately pushed to the corner of the guide groove 2011 by the torsion spring 203, so that not only is the combination of the bottom structure at the front end of the reagent kit and other parts of the reagent tray realized, but also the longitudinal positioning of the reagent kit is realized.

In the process of placing the reagent kit, even if the bottom structure at the front end of the reagent kit is not accurately combined with the corresponding parts of the reagent disk, the normal use of the reagent kit still cannot be influenced, because under the condition, the longitudinal positioning of the reagent kit is still effective and cannot be separated from the positioning block, and after the reagent disk operates, the bottom structure at the front end of the reagent kit can be automatically and accurately combined with the corresponding parts of the reagent disk, which depends on the ingenuity of structural design.

When the reagent kit is taken out, the reagent kit can be taken out from the positioning block only by applying a small force to the rear part of the reagent kit and then lifting upwards.

Preferably, the poking direction of the end of the torsion spring 203 serving as the poking part and the opening direction included angle of the guide groove are acute angles, when the end of the torsion spring 203 slides downwards, the torsion spring 203 extrudes and deforms, a reverse acting force is applied to the reagent kit in order to restore the elastic deformation, the direction of the acting force and the extending direction of the guide groove 2011 are acute angles, namely, the reagent kit always receives the pushing force in the direction of the guide groove 2011, and the reagent kit 100 can be immediately pushed to the corner of the guide groove 2011 by the torsion spring 203.

Preferably, an opening is arranged above the positioning block main body 201, and a positioning block cover 202 is arranged at the opening.

Preferably, the side surface of the reagent box is provided with an auxiliary positioning structure 102; the positioning block main body 201 is provided with an auxiliary positioning groove 2012, the auxiliary positioning structure 102 is vertically embedded in the auxiliary positioning groove 2012, and a side surface of the auxiliary positioning structure 102 is attached to a side surface of the auxiliary positioning groove 2012.
