Description

Technical Field

[0001] This utility model relates to the field of laboratory animal instruments, specifically to an animal sleep deprivation device. Background Technology

[0002] An animal sleep deprivation device is an experimental apparatus used to study animal sleep patterns, sleep mechanisms, and their effects on physiology and behavior. It achieves the effect of sleep deprivation by interfering with or preventing animals from entering a sleep state through specific physical or environmental stimuli.

[0003] Existing sleep deprivation devices typically place the feed troughs and water troughs outside the chamber for easy addition of feed and drinking water. However, experiments involving energy metabolism require the measurement of carbon dioxide and oxygen levels inside the chamber. This necessitates minimizing gas exchange between the chamber and the outside environment during the experiment. Placing the feed troughs and water troughs outside the chamber allows for gas exchange with the outside environment, leading to inaccurate measurement results.

[0004] Patent document CN213343917U discloses a sleep deprivation device suitable for rodents, including a sleep deprivation rotating mechanism, a sleep deprivation rod, and a box structure that provides food and water to the animals. The output end of the sleep deprivation rotating mechanism is connected to the sleep deprivation rod, which is housed within the box structure, which is a transparent box. However, the food and water troughs in this patent are located outside the enclosure, leading to gas exchange between the food and water troughs and the outside environment, resulting in inaccurate measurement results.
