Device for accurately measuring water intake of non-human primate experimental animal

Abstract

The invention relates to a device for accurately measuring the water intake of a non-human primate experimental animal. The device comprises a water drinking device body and a recycling water tank, wherein a water tank is arranged at the upper part of the water drinking device body, and a water drinking pipe control valve assembly is arranged at the lower part of the water drinking device body; the water drinking pipe control valve assembly comprises a backflow type water outlet head, a backflow cover, a connecting tube, a valve control arm and a lifting type water valve; the lower end of the backflow type water outlet head communicates with the left end of the connecting tube, and the backflow type water outlet head is obliquely distributed upwards relative to the connecting tube; a connecting tube rotating shaft support is correspondingly arranged in the water drinking device body, rotating shafts are correspondingly arranged on the outer walls of the two sides of the connecting tube, and the connecting tube can be rotationally distributed on the connecting tube rotating shaft support through the rotating shafts; and one end of the lifting type water valve communicates with the lower end of the water tank through a water outlet pipeline, and the other end of the lifting type water valve communicates with the right end of the connecting tube through a water supply hose. The device has the advantages of being accurate in metering, high in anti-interference capacity, easy to domesticate, good in using effect and the like.

Description

technical field [0001] The invention relates to the technical field of precise measurement of drinking water volume of non-human primate experimental animals, in particular to a device for accurately measuring the drinking water volume of non-human primate experimental animals. Background technique [0002] Non-human primate experimental animals are generally kept in monkey cages in the animal room. The monkey cages are generally equipped with high-pressure drinking water pipes, which can "inform" non-human primate experimental animals that there is water here by dripping water continuously. Then, the non-human primate experimental animals can be easily touched by the push-type valve switch, and then the drinking water can be sprayed out. Drink slowly. However, for some experiments that require accurate measurement of water intake of non-human primate experimental animals (for example, related experiments involving diabetic animal models require monitoring of water intake a...

AI Technical Summary

Problems solved by technology

However, for some experiments that require accurate measurement of water intake of non-human primate experimental animals (for example, related experiments involving diabetic animal models require monitoring of water intake and urination), it is impossible to use traditional drinking devices and drinking methods. If the actual amount of drinking water is known, because the amount spilled by the above-mentioned traditional method is much higher than the actual drinking amount or sometimes the non-human primate experimental animals do not drink after holding water in the palm, so it is wrong to simply count the amount of water flowing out, and to pass it in The corresponding simple recovery funnel under the breeding cage cannot achieve the required accuracy. The main reason is that the high-pressure water pipe spraying water can not guarantee effective recovery, and the sprayed water will be blocked by the palm of the experimental animal. After the water is filled, it will move around. It is possible to walk around after the palm is filled with water. It is not necessarily true that the undrinkable water in the palm can be effectively recycled. At the same time, there is a recycling funnel directly. Experimental animals are also mixed into the recycling meter due to urinating everywhere.

Using an overly complicated design may be able to avoid the above-mentioned problems, but because humans and non-human primate experimental animals cannot communicate verbally or there are large differences in the logic of understanding foreign objects, it is necessary to focus on non-human primate experiments. Whether the animal is easy to accept or easy to understand and understand / will use the device for drinking water (that is, the problem of domestication difficulty)
