At the same time, clean air supplied through the HEPA filter is supplied to the animals in the cage to allow the animals to breathe, and odors in the cage are discharged to the outside through the air outlet at the rear to maintain the animal breeding environment comfortably. It relates to a laboratory animal breeding device.

Various experimental small animals (hereinafter referred to as "experimental animals"), such as mice, rats, rabbits, morphotes, and hamsters, which are raised for medical experiments or purposes, are raised and managed in various environments depending on the purpose of breeding. It is becoming.

As a laboratory animal breeding device, a shelf-type breeding shelf that breeds cages simply by placing cages on a shelf without special mechanical and electrical components, and feeds the breeding shelf into cabinet-type boxes and supplies air to the entire cabinet. There are a clean rack with a device for discharging and a device for discharging, and an individual ventilation breeding rack for supplying and exhausting air to a cage opposite the breeding shelf.

In general, the opposite of the breeding rack is simply a cage on the shelf, so it is the most widely used form, and it is inexpensive and easy to handle. The vicious cycle in which the environment is worsened by the repetition phenomenon that the air is supplied to the animals to be reared and the concentration gradually increases. As a result, when one of the animals raised is infected with the disease, another animal that inhales the same air is also infected with the disease, and many animals in the same animal room die at once, or the infection loses its value as an experimental animal for a long time. There is a case where the experiment fails.

The clean rack method puts the breeding rack in an airtight box such as a cabinet and supplies the filtered air to the animal and exhausts it. It is possible to keep the animal breeding room clean. However, due to the airflow inside the clean rack, dust is generated from the litter and the food to provide a polluted environment to the animal, and since the enclosure is a closed cabinet, if the animal is polluted, the contamination spreads rapidly throughout the clean rack Rather, there is an element that can have more adverse effects on the animals than the general breeding opposition.

It is designed to supplement the clean rack system is a breeding rack of the individual ventilation type of supplying and exhausting air to each cage of the breeding shelf. Individual ventilation breeding racks provide independence to each cage to eliminate cross-contamination and provide a pleasant environment for breeding animals and breeders.
