Problems solved by technology

So far, there is no instrument to observe the preference of hot and cold drinks in rats. Artificial feeding is disturbed by external human factors, and there is no objective index, and it cannot well reflect the trend of hot and cold drinks in rats.

Embodiment Construction

[0022] The structure of the present invention has been described above, and the use of this instrument is such that at first two water storage bottles are filled with equal amounts of water, and the power supply (such as Figure II As shown), at this time, the switching power supply a starts to work to provide power for the temperature control resistor b and the cooling sheet c, and the cooling sheet starts to work to cool the outlet pipe 2 close to its cooling side, and to cool the outlet pipe 2 close to its heat dissipation surface 2 heating. The temperature control resistor is installed at the hot water end 8 of the water outlet pipe to feel the water temperature of the pipe, so when the preset temperature reaches 40°C, an instruction is sent to the cooling plate to stop working, and when the water temperature in the pipe drops to less than 40°C , then re-instruct it to start working, and now the water temperature of the other outlet pipe can be kept at about 4°C.

Abstract

The invention relates to a rat cold hot drink preference determinator. The invention belongs to the animal experimental apparatus field and is mainly used for investigating whether a rat likes drinking hot water or cold water and providing an objective quantitative index, thereby investigating the cold or hot body state of the rat or investigating whether a pathological attribute during a disease is a hot property symptom or a cold property symptom. The invention is provided with a water bottle connected with a water outlet pipe, wherein the latter provides drinking water for the rat. A switching power supply provides a power supply of 5V for a refrigeration piece, a temperature control resistor can sense the temperature of hot water to further control the working status of the refrigeration piece and consequently control the water temperature, and a water collection barrel collects the water which is carelessly dropped by the drinking rat. The observation of the reduced water amount in the water bottle and the water collection amount in the water collection barrel can obtain the water intake amount of the rat, thereby judging the cold hot drink preference of the rat.

Description

technical field [0001] The invention relates to the field of animal experiment equipment. Background technique [0002] Medical research requires animal experiments. As organisms, many diseases or phenomena that occur in humans can also occur in animals. However, research on diseases or medicines sometimes cannot be directly used in humans, so it is necessary to pass Do animal experiments to verify some of our theories or to discover some objective laws. According to the theory of traditional Chinese medicine, "when yin is strong, it is cold, and when yang is strong, it is hot". Here, cold or heat reflects a pathological change inside the human body. Generally speaking, organisms with a hot constitution like cold food or drinking water, and vice versa. like warm food or drinking water. So far, there is no instrument to observe the preference of hot and cold drinks in rats. Artificial feeding is disturbed by external human factors, and there is no objective index, and it ca...
