[0029] In an optional embodiment of the utility model, the first mark 20, the second mark 30 and the third mark 40 can be engraved on the substrate 10, or the first mark 20, the second mark 30 and the third mark 40 can be set as components separated from the substrate 10, such as a first ruler, a second ruler and a third ruler, so that the first ruler, the second ruler and the third ruler can be detachably connected to the substrate 10 respectively. In this way, the manufacturing difficulty of the substrate 10 can be reduced and its transportation can be facilitated.
[0030] See also Figure 1 It can be understood that the background plate for in vitro mouse tumor measurement and photography provided by the embodiment of the utility model, by setting the first mark 20, the second mark 30 and the third mark 40 on the substrate 10, and making the first mark 20 and the third mark 40 parallel and spaced, and making the two perpendicular to the second mark 30 respectively, in this way, a complete reference system can be constructed on the substrate 10, so that when it is necessary to measure and photograph the in vitro mouse tumor, the in vitro mouse tumor can be directly placed on the substrate 10 for photography, so that the first mark 20, the second mark 30 and the third mark 40 can be directly used as references in the finished photo to accurately read the size information of the in vitro mouse tumor; in addition, an experimental group and a control group can be set, and the first mark 20 and the third mark 40 can be used as references respectively, so that the difference between the experimental group and the control group can be directly identified in the finished photo, and the characteristics of the experimental group can be identified, so that the operation time of in vitro mouse tumor photography and measurement can be greatly reduced, and the efficiency of in vitro mouse tumor photography and measurement can be improved.
[0031] Compared with the prior art, the background plate for measuring and photographing in vitro mouse tumors provided in the embodiment of the utility model has a first mark 20, a second mark 30 and a third mark 40 set on the substrate 10. Thus, after the measurement and photographing of the in vitro mouse tumors are completed, the size information of the in vitro mouse tumors can be directly read out, eliminating the step of synthesizing the coordinate system through a computer, which can reduce the operation time of photographing and measuring in vitro mouse tumors and save manpower and material resources.
[0032] Continue reading Figure 1 In an optional embodiment of the utility model, a plurality of third identifiers 40 are provided, and the plurality of third identifiers 40 are arranged in parallel and spaced apart along the length direction of the second identifier 30. A first measurement area can be limited between the third identifier 40 closest to the first identifier 20 and the first identifier 20. Along the length direction of the second identifier 30, a second measurement area, a third measurement area, a fourth measurement area, a fifth measurement area and even an nth measurement area can be limited in sequence between the spaced apart third identifiers 40. The number of measurement areas (i.e., the specific value of n) can be adaptively set according to actual conditions. In other words, the number of third identifiers 40 can be adaptively set according to actual conditions.
[0033] See also Figure 1 It can be understood that, in the embodiment of the utility model, by setting a plurality of third marks, a plurality of measurement areas can be distinguished. In this way, when photographing and measuring the ex vivo mouse tumor, a plurality of experimental groups or reference groups can be placed at the same time. In this way, the samples of the ex vivo mouse tumor can be photographed and measured in batches, which can greatly improve the efficiency of photographing and measuring the ex vivo mouse tumor. In the experimental process where a large number of ex vivo mouse tumors need to be photographed, the experimental time can be greatly reduced and the cost of manpower and material resources can be reduced.
[0034] Continue reading Figure 1 In an optional embodiment of the utility model, the distance between the first mark 20 and the nearest third mark 40 is a, wherein the value range of a is 2-5 cm. For example, a can be 2 cm, 3 cm, 4 cm, or 5 cm. It can be understood that by limiting the distance between the first mark 20 and the nearest third mark 40 to within the above range, the sizes of the first measurement area and the second measurement area can be standardized, and the two measurement areas can be made more regular, which is beneficial to the accuracy of the photographic measurement experiment and is beneficial to improving the standardization of the photographic measurement experiment.
[0035] Continue reading Figure 1 In an optional embodiment of the utility model, the spacing between any two adjacent third marks 40 is b, wherein the value range of b is 2-5 cm. For example, b can be 2 cm, 3 cm, 4 cm, or 5 cm.

[0036] In an optional embodiment of the utility model, the substrate 10 includes a polypropylene substrate, and the thickness of the polypropylene substrate can be set to 0.5 cm. It can be understood that the polypropylene material is a thermoplastic synthetic resin with excellent performance, which is a colorless, translucent, thermoplastic, lightweight general-purpose plastic, and is non-reflective. Using such a material to manufacture the substrate 10 can make the substrate 10 also have a good non-reflective property. The non-reflective property is conducive to the shooting of photos, can avoid the interference of stray light on the lens, and improve the accuracy of the photos.
[0037] Figure 2 It is an axial side view of a background plate for in vitro mouse tumor measurement and photography provided by an embodiment of the utility model.
[0038] See also Figure 2In an optional embodiment of the utility model, a plurality of drainage holes 50 are further provided on the substrate 10, and the plurality of drainage holes 50 are evenly spaced on the substrate 10. It can be understood that the isolated mouse tumor is generally a fresh sample, and the sample itself may be adhered to some blood or other body fluids. By providing the drainage holes 50 on the substrate 10, when the isolated mouse tumor is placed on the substrate 10, the liquid carried by the isolated mouse tumor itself will flow out along the drainage holes 50. In this way, on the one hand, it is convenient to clean the substrate 10, and on the other hand, it is conducive to the discharge of the body fluid of the isolated mouse tumor; the specific setting of the drainage holes 50, such as size, spacing and other specific dimensions, can be adaptively set according to actual conditions, and the embodiment of the utility model does not make specific limitations on this.
[0039] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the background plate used for in vitro mouse tumor measurement and photography also includes a liquid collecting trough 60, which is arranged below the substrate 10 and corresponds to the position of the drain hole 50. It can be understood that when the liquid carried by the in vitro mouse tumor itself flows out along the drain hole 50, the waste liquid can be collected by the liquid collecting trough 60, which is conducive to maintaining the cleanliness of the experimental environment and can reduce the number of times the experimental environment is cleaned.
[0040] In an optional embodiment of the utility model, the liquid collecting trough 60 and the substrate 10 are integrated components. For example, by injection molding, the substrate 10 with the liquid collecting trough 60 can be obtained in an integrated manner. This can reduce the components of the background plate used for in vitro mouse tumor measurement and photography, and reduce the assembly steps. In an optional embodiment of the utility model, the liquid collecting trough 60 can also be a different component from the substrate 10, and the two can be detachably connected or simply aligned. In this way, on the one hand, it is convenient for processing, manufacturing and transportation, and on the other hand, it is convenient for cleaning of waste liquid.
[0041] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the background plate for in vitro mouse tumor measurement and photography further includes a partition 70, which is disposed on one side of the third mark 40 and extends synchronously with the third mark 40. It can be understood that the sample shape of the in vitro mouse tumor is usually relatively round and is easy to move during the placement process. In order to avoid changes in the position of the tumor tissue, different in vitro mouse tumor samples can be separated by providing the partition 70. In other words, the aforementioned different measurement areas can be separated, and mutual influence between experimental groups and between experimental groups and control groups can be avoided, so as to ensure the integrity of the samples during the photography and measurement experiment.
[0042] Continue reading Figure 1 and Figure 2In an optional embodiment of the utility model, the partition 70 is detachably connected to the substrate 10. It can be understood that such a configuration is conducive to the processing and manufacturing of the partition 70 and the substrate 10, as well as transportation. At the same time, when the volume of the in vitro mouse tumor sample is large, the size of the measurement area can be adjusted by adding or removing the partition 70 to meet the actual needs of in vitro mouse tumor samples of different sizes.
[0043] Continue reading Figure 1 and Figure 2 In an optional embodiment of the utility model, the background board for in vitro mouse tumor measurement and photography also includes a leveling component 80, which is arranged below the substrate 10. The leveling component 80 is used to adjust the level of the substrate 10. It can be understood that when the desktop or laboratory table where the substrate 10 is set is uneven, the leveling component 80 can be used to ensure the level of the substrate 10 to meet the shooting requirements. The leveling component 80 can specifically adopt lifting legs. Specifically, the level of the substrate 10 can be adjusted by adjusting the height of the lifting legs at different positions.
[0044] It should be noted that the technical solutions in various embodiments of the present utility model can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in the field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist, that is, it does not belong to the protection scope of the present utility model.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
