Description

The disadvantages of the known cage systems for keeping small laboratory animals is that they do not provide sufficiently hygienic maintenance of these animals and do not have the full mechanization of the most labor-intensive work to care for them.

These deficiencies do not have a cell sredgema for keeping small laboratory animals (mice, rats, sea mammals' hamsters), in which suspended, retractable box-shaped cells made of anticorrosive materials are used in complex, each of which has: a supplementary lid, a plug-in transverse partition and an opening instead of a door , and mechanization tools for feeding, watering and manure removal. To do this, a bunker-type feeding trough can be inserted into the cage opening, and spout bowls connected to the aqueduct and an external tank for liquid food can be inserted into its openings.

The mechanization of the manure is provided by conveyors in the form of endless strips of iodine by paired cells, which are electrically mixed and covered at one end with fresh bedding, such as sawdust, and at the other they are cleaned with cylindrical power brushes and moistened with disinfectant solution using soft rollers.

FIG. Figure 1 shows the proposed cell system for keeping small laboratory animals (mice, rats, hamsters and guinea pigs), front view, fig. 2 - single cell.

Each cell / is in the form of a box of anti-corrosive material and has bent edges 2 in the upper part, with which it slides into the guides of the multi-wall frame rack 3 and is held in a suspended state. Four paired cells are placed in each tier of the rack. In this case, the top branch of the belt conveyor 4 serves as the bottom for the paired cells, at which # 145411-2 -

electrically driven, its belt from one end of bunker 5 is covered with fresh bedding, such as sawdust, and on the other, dirty litter is removed from it by a cylindrical drive brush 6. The lower branch of the conveyor is moistened with a disinfectant solution using a soft roller 7 partially immersed in bath 8 with the specified solution.

A transverse partition can be inserted into each cage to divide it into two parts, which is necessary when working with experimental animals. In the opening of the anterior wall of each cell can be inserted-bunker-type 9. Animals receive running water from the aqueduct and liquid feeds from the external reservoir by means of insert nozzle cups, which are installed in the openings of the cage wall.

For carrying the cage with experimental animals, an appropriate tray 10 is brought under it.

The proposed cell system for keeping small laboratory animals (mice, rats, hamsters, and guinea pigs) has been approved.

Subject invention

A cage system for keeping small laboratory animals (mice, rats, hamsters, and guinea pigs) in the form of a double-sided, multi-rack racks-shelves, characterized in that, in order to ensure the hygienic content of these animals using the mechanization of the most labor-intensive work. them, complexly applied; suspended retractable box-shaped cells with a base in the form of a trans-porter, - under the paired cells, which moves - from the electric drive and is covered with fresh bedding from one end, - for example, sawdust, and from the other - is cleaned from it with a cylindrical power brush and moistened with disinfectant soft roller; cages of anticorrosive materials, each of which is provided with a lid, an insertable transverse partition and an opening instead of a door, closed by a bunker-type insertion feeder; supplying animals with running water and liquid food - by means of spout cups inserted into the wall apertures of each cage, connected to a water supply system and to an external tank for liquid food.
