Description

[Technical Field]

[0001] The present invention relates to a cradle assembly and an in-vitro diagnostic instrument assembly including the same, and more particularly to a cradle assembly that can be coupled in various ways to support different sizes and an in-vitro diagnostic instrument assembly including the same. [Background technology]

[0002] Recently, a variety of simple test reagents, diagnostic drugs and diagnostic devices have been developed to diagnose whether or not a person is infected with a pathogen such as a virus or bacteria, whether or not they are pregnant, whether or not they have developed cancer, and whether or not harmful substances such as pesticide residues are present in specific raw materials such as food.

[0003] In particular, in vitro diagnostic technology is a technology that uses substances derived from the human body, such as blood, feces, urine, body fluids, and saliva, to quickly diagnose diseases outside the body, and it plays an important role in clinical decision-making, becoming an essential and specialized element in patient treatment.

[0004] In vitro diagnostic devices using this technology are medical devices containing reagents used in tests using tissue, blood, urine, and other specimens collected from the human body for purposes such as diagnosing disease, determining prognosis, assessing health, determining the effectiveness of treatment for disease, and preventing disease. These devices are less physically demanding than medical devices that are inserted into the human body and perform diagnosis outside the body.

[0005] These in vitro diagnostic devices are available in various sizes depending on the type of test, and are connected by stacking or other methods to perform all of the tests at once. When stacking in vitro diagnostic devices, the structures and sizes required to fasten each device are different, so it is necessary to develop a cradle structure that can stably support the stacked in vitro diagnostic devices. Summary of the Invention [Problem to be solved by the invention]

[0068] In this state, the front faces of the first cradle 10 and the second cradle 50 are aligned, allowing the rear faces of the two stacked in-vitro diagnostic devices 100 to be supported simultaneously, and the second support member 70 provided on the upper surface of the second cradle 50 can support the rear faces of the three-layer stacked in-vitro diagnostic devices 100.

[0069] 2nd Assembly Example

[0070] FIG. 7 is a diagram illustrating another example of an assembled cradle assembly according to one embodiment of the present invention, FIG. 8 is a diagram illustrating the coupling portion of the cradle assembly illustrated in FIG. 7, and FIG. 9 is a cross-sectional view illustrating the coupling portion of the cradle assembly illustrated in FIG. 7.

[0071] Referring to this, the first cradle 10 and the second cradle 50 can be assembled by connecting the lower surface of the first cradle 10 to the upper surface of the second cradle 50. At this time, the second cradle 50 can be moved rearward compared to the previous embodiment. The first insertion rib 60 is inserted into the third guide rib 26 of the third guide slit 27 and connected, and the front surface of the second cradle 50 is positioned rearward of the front surface of the first cradle 10, and the rear surface of the second cradle 50 is aligned with the rear surface of the first cradle 10.

[0072] In this state, the second cradle 50 is positioned rearward, so that if the in-vitro diagnostic devices 100 stacked in two layers are large enough to protrude rearward, the rear surfaces of the in-vitro diagnostic devices 100 can be stably supported. In addition, the second support member 70 provided on the upper surface of the second cradle 50 can support the rear surfaces of the in-vitro diagnostic devices 100 stacked in three layers.

[0073] 3rd Assembly Example

[0074] FIG. 10 is a diagram illustrating another example of an assembled cradle assembly according to one embodiment of the present invention, FIG. 11 is a diagram illustrating the coupling portion of the cradle assembly illustrated in FIG. 10, and FIG. 12 is a cross-sectional view illustrating the coupling portion of the cradle assembly illustrated in FIG. 10.

[0075] Referring to this, in this assembly example, the second cradle 50 can be turned upside down and the top surface of the second cradle 50 can be coupled to the top surface of the first cradle 10. At this time, the second support member 70 is inserted into the second guide slit 25 of the second guide rib 24, and the third insertion rib 72 is inserted into the second guide slit 23 of the first guide rib 22 and coupled. The front surface of the second cradle 50 is located behind the front surface of the first cradle 10, and the rear surface of the second cradle 50 is positioned to coincide with the rear surface of the first cradle 10.

[0076] In this state, the second cradle 50 is positioned rearward, so that if the in-vitro diagnostic devices 100 stacked in two layers have a size that protrudes rearward, the rear surfaces of the in-vitro diagnostic devices 100 can be stably supported. In addition, the first support member 62 provided on the underside of the second cradle 50 can support the rear surfaces of the in-vitro diagnostic devices 100 stacked in three layers. In this case, the first support member 62 is positioned at a position corresponding to the front surface of the second cradle 50, so that the rear surfaces of the in-vitro diagnostic devices 100 stacked in three layers and having a small size can be stably supported.

[0077] Figure 13 is a side view illustrating an in vitro diagnostic instrument assembly according to one embodiment of the present invention, Figure 14 is a side view illustrating an in vitro diagnostic instrument assembly according to another embodiment of the present invention, and Figure 15 is a side view illustrating an in vitro diagnostic instrument assembly according to yet another embodiment of the present invention. Figure 13 illustrates the cradle assembly illustrated in Figure 5, Figure 14 illustrates the cradle assembly illustrated in Figure 8, and Figure 15 illustrates the cradle assembly illustrated in Figure 11.

[0078] The in-vitro diagnostic device 100 is coupled to the front of the cradle assembly, but may have different sizes at the front and rear. The drawings show a first in-vitro diagnostic device 110 and a second in-vitro diagnostic device 120 each having different sizes at the front and rear.

[0079] 13, two second in-vitro diagnostic devices 120 may be stacked on the top surface of a relatively large first in-vitro diagnostic device 110. In this case, the in-vitro diagnostic device 100 must be stacked on the upper layer with its front surface moved backward. Therefore, the rear surfaces of the second in-vitro diagnostic devices 120 stacked in three layers may protrude backward. In this case, the weight of the second in-vitro diagnostic devices 120 may cause the in-vitro diagnostic devices 100 to tip backward.

[0080] In this case, if the in-vitro diagnostic device 100 is supported by an assembled cradle assembly as in this embodiment, the rear surfaces of the in-vitro diagnostic device 100, which are stacked in one and two layers, of the first in-vitro diagnostic device 110 and the second in-vitro diagnostic device 120, can be integrally supported, and the rear surface of the second in-vitro diagnostic device 120, which is stacked in three layers, can be supported by the second support member 70.

[0081] 14, second in-vitro diagnostic devices 120 having the same size may be stacked in three layers. In this case, the rear surfaces of the second in-vitro diagnostic devices 120 stacked in two or three layers may protrude backward. In this case, the weight of the second in-vitro diagnostic devices 120 may cause the in-vitro diagnostic device 100 to tip backward.

[0082] In this case, if the in-vitro diagnostic device 100 is supported by the assembled cradle assembly as in this embodiment, the rear of the second in-vitro diagnostic device 120, which is stacked in two or three layers, can be stably supported. Also, although the drawings only show the second in-vitro diagnostic device 120 stacked in three layers, the cradle assembly can be assembled as described above to support the rear of the first in-vitro diagnostic device 110 even when the first in-vitro diagnostic device 110 is stacked in three layers.

[0083] 15, the first in-vitro diagnostic device 110 may be stacked on the first and second layers, and the second in-vitro diagnostic device 120 may be stacked on the third layer. In this case, the rear surfaces of the first in-vitro diagnostic device 110 and the second in-vitro diagnostic device 120 stacked on the second and third layers may protrude backward. In this case, the weight of the first in-vitro diagnostic device 110 and the second in-vitro diagnostic device 120 may cause the in-vitro diagnostic device 100 to fall backward.

[0084] In this case, if the in-vitro diagnostic device 100 is supported by the assembled cradle assembly as in this embodiment, the rear surfaces of the first in-vitro diagnostic device 110 and the second in-vitro diagnostic device 120, which are stacked in two or three layers, can be stably supported. The rear surface of the second in-vitro diagnostic device 120, which is stacked in three layers, can be supported by the first support member 62.

[0085] FIG. 16 is a perspective view illustrating a mounting bracket for an in vitro diagnostic device, and FIG. 17 is a view illustrating a coupling portion of the in vitro diagnostic device.

[0086] 1, a mounting bracket 102 for coupling with another in vitro diagnostic device 100 is coupled to the top surface of the in vitro diagnostic device 100, and the mounting bracket 102 may have a plurality of protruding fastening protrusions 104. The mounting bracket 102 may be plate-shaped and may be placed in a recessed portion on the top surface of the in vitro diagnostic device 100.

[0087] The in-vitro diagnostic device 100 may have a protruding fixing protrusion 108 on the underside thereof, to which the fastening protrusion 104 is hooked, and the fastening protrusion 104 may have a recessed protrusion groove 105 into which the fixing protrusion 108 is inserted. Therefore, when the stacked in-vitro diagnostic devices 100 are slid forward in a pre-assembled state, the fixing protrusion 108 is inserted into the protrusion groove 105, thereby allowing the devices to be stably coupled.

[0088] Although the present invention has been described above with reference to specific embodiments, it will be understood by those skilled in the art that various modifications and variations of the present invention may be made without departing from the spirit and scope of the present invention as set forth in the following claims.
