Description

Technical Field

[0001] This application relates to the field of open-field experimental equipment technology, and more specifically, to a retractable animal open-field detection device. Background Technology

[0002] The open field test (OFT), also known as the open box test, is a commonly used animal behavior experiment. OFT can detect spontaneous activity and exploratory behavior in rats or mice, and is a method for evaluating the autonomous behavior, exploratory behavior, and stress levels of laboratory animals in unfamiliar environments.

[0003] For example, animals may be afraid of new and open environments and tend to stay in the periphery, moving less in the central area. However, their exploratory nature can motivate them to stay in the central area. Meanwhile, other traditional urodynamic testing methods (such as urodynamic instruments) have drawbacks such as complex operation, invasiveness, and low repeatability. Experiments have shown that using open-field testing to monitor changes in urination behavior in rats or mice over a long period has significant advantages and can be used as a method to evaluate urinary incontinence in experimental animals (such as mice and rats) and the effectiveness of treatment.

[0004] Currently, although there are various urine stain test devices on the market, such as those using plastic boxes or custom-made wooden boxes, they generally suffer from poor adaptability, cannot flexibly adjust the test space, and are difficult to meet the actual needs of mice and rats at the same time.

The distal end can be provided with a first position and a second position. When the sliding connectors 130 are located at the first position, the folding supports 120 form a first support, and thus the folding frame 100 can form a first frame 100a. When the sliding connectors 130 are moved to the second position, the folding supports 120 form a second support, and thus the folding frame 100 can form a second frame 100b.

[0068] For example, referring to Figure 1 , Figure 4 and Figure 5 , the folding frame 100 can be provided as a rectangular frame. The number of column assemblies 110 can be four, specifically, a first column assembly 110, a second column assembly 110, a third column assembly 110, and a fourth column assembly 110.

For example, the first body 131 can be provided with two first recesses 133a. One first recess 133a is located at the left side of the first body 131, and the other first recess 133a is located at the upper side of the first body 131, i.e. the first body 131 is provided with two perpendicular first recesses 133a.

[0078] Optionally, referring to Figure 7The second connecting part 134 includes a second groove 134a, which is disposed on the first body 131 and is used to connect with the first splicing plate 200a and the second splicing plate 200b.

[0079] In this embodiment, a second groove 134a is provided on the first body 131, that is, the sliding connector 130 is spliced ​​with the side plate 200 through the second groove 134a.
