Description

Technical Field

[0001] The invention relates to the technical field of skin photoaging experiments, in particular to a modeling device for mouse skin photoaging experiments. Background Art

[0002] Skin photoaging is a type of exogenous skin aging, which is skin damage caused by repeated exposure to natural light or artificial ultraviolet light sources. In recent years, due to the destruction of the ozone layer and the increase in ultraviolet radiation, the incidence of photoaging has increased year by year, seriously threatening people's health and life. In medical research, skin aging has become a hot scientific issue that concerns everyone. Among them, exogenous skin aging is a type of aging that can be intervened through active prevention and repair. The main cause of exogenous skin aging is aging caused by ultraviolet light, and mouse skin photoaging experiments are an indispensable means for studying exogenous skin aging. Skin photoaging experiments are usually conducted on mice. Box-type experimental containers are used to simulate the ultraviolet irradiation environment of natural light proportions, and the skin on the back of mice is irradiated.

[0003] The announcement number is: CN221308371U, which discloses a modeling device for mouse skin photoaging experiments. The modeling device has the advantages of separating the placement of farmed mice through a box body, a box cover, a simulated sunlight mechanism, a partition, a display, a feed delivery port, and a ventilation window, so as to prevent the mice from gathering and lying flat. Through the cooperation of a rotating rod, a connecting plate, EVA and EVB light sources, gear one, a servo motor and gear two, it has the advantages of simulating light experiments. A row of light sources is arranged in the box body, which rotates at a certain speed along the top of the box cover. However, when the above-mentioned modeling device is in use, although the mice can be separated by the partition, the passage after separation is long, which is not convenient for irradiating the mouse skin at a fixed position. In addition, the light source in the above-mentioned modeling device will rotate around a point, but the irradiation position change range of the light source in the center position is small, and this irradiation range is gradually reduced. Combined with the movement of the mice in the passage and the rotation of the light source, it is easy to cause inaccurate experimental data.

When the first magnet 34 and the second magnet 35 When the fixed slide plate 21 is in close contact, the first magnet 34 and the second magnet 35 are attracted to each other. When the irradiation experiment is completed, the output end of the motor 25 drives the threaded rod 24 to rotate in the opposite direction, so that the fixed slide plate 21 moves to the initial position.

The manipulator 16 controls the first electric push rod 31 to start at the same time, so that the output end of the first electric push rod 31 drives the mounting frame 30 to move, and the plug is separated from the leak hole. During the movement of the fixed slide 21 and the telescopic slide 22, the feces discharged by the mouse at the upper end of the bottom plate 13 can be discharged into the collection box 14 through the leak hole for collection. When the lever 27 is in close contact with the flat end of the guide plate 26, the adjustment partition 19 no longer moves. When the experimental channel space only allows the mouse to stand and cannot move, the fixed slide 21 stops moving, and the first magnet 34 and the second magnet 35 are attracted to each other. Subsequently, the switch of the ultraviolet lamp source 38 is controlled by the manipulator 16 to carry out an irradiation experiment. When the irradiation position of the ultraviolet lamp source 38 needs to be adjusted, the second electric push rod 42 is started, and the second electric push rod 42 drives the third mounting rod 41 to move, and the third mounting rod 41 drives a plurality of hinge rods to move, and the hinge rod drives the focus cover 39 to move through the connecting rod 40, and the movement directions of the two ultraviolet lamp sources 38 above an experimental channel are opposite, so that the irradiation position of the ultraviolet lamp source 38 is adjusted. When the irradiation angle of the ultraviolet lamp source 38 needs to be adjusted, the third electric push rod 47 is started, and the output end of the third electric push rod 47 drives the fourth mounting rod 46 to move, and the fourth mounting rod 46 drives a plurality of racks 45 to move, and the racks 45 are meshed with the gears 44, so that the focus cover 39 is driven to rotate, and the focus cover 39 drives the ultraviolet lamp source 38 to rotate, so that the irradiation angle of the ultraviolet lamp source 38 is adjusted, thereby simulating different irradiation positions.
