Description

Breeding cages for small animals {.}

The present invention relates to a breeding cage for small animals, more specifically, when breeding small breeds such as mice, rats, and hamsters for breeding, rearing, mooring, and experimenting, breeding grounds of the Middle East such as rabbits, cats, and dogs. The present invention relates to a small animal breeding cage which can be useful for raising a young, mooring, temporary storage, inpatient treatment at a veterinary clinic, and raising a small pet.

Modern high-tech science is the foremost field of life science. Experimental animals are inevitably used for research on food resources, environmental management, medicine development, genetic engineering, and medical technology development.

The experimental animals used in this way are tested for their biological changes while breeding for a few days to several years or decades.

In the long-term breeding process, the control of the experimental animals according to the experimental conditions (feed, drinking, feeding and drinking bowls, feces cleaning, different conditions depending on the experimental conditions and the type of animals, Scientists are eager to experiment under optimal environmental conditions by observing behavior.

Despite these requirements, however, despite the fact that the specification conditions must be different due to defects in existing breeding cages and economic reasons, experimental animals that require different specification conditions may be used in the same room. Often breeding.

In particular, even though the environmental temperature required according to the type of laboratory animals in the temperature control is different, the results of the experiment are frequently distorted due to the forced experiment.

In addition, in the process of breeding experimental animals, failure to obtain normal test results due to bad smell and fermentation gas generated from feces may result in different experimental results, or respiratory diseases may occur and ruin the entire experiment.

In particular, the development of an infectious disease has also led to the destruction of a long-term study when the entire experimental group becomes ill.

On the other hand, in the process of raising a large number of laboratory animals and pups in the breeding grounds, when an infectious disease occurs due to a bad breeding environment, many animals die at once or lose their value as experimental animals due to infection. Exposed, but there is no way to improve existing farms.

The interest in pets is increasing due to the improvement of people's living standards, and it is increasing the need to keep animals in public places such as animal hospitals, dog centers, dog breeding grounds, and department stores.

At this time, veterinary clinic has a large number of manpower to manage due to lack of temporary storage facilities in public places such as breeding barrels and mooring facilities, dog centers and breeding centers for breeding and mooring facilities, and department stores. Of course, there is a possibility of a lot of diseases, as well as indoor air pollution because there is no ventilation and dirt discharge function.

Experimental animals, such as rodents as described above, put a rug in a quadrangular barrel, such as a plastic bowl with four sides and a bottom, so that urine and feces are absorbed by the rug, so that they can not be processed quickly, and thus indoor air It is acting as a major contaminant.

Therefore, the breeding room (facility) to accommodate the breeding box varies depending on the conditions, but despite the relatively good conditions, there is no individual ventilation device or individual discharge device, which is a defect of the breeding box classified by individual or group, so that gas and odor from urine and feces It is a situation that breeding them in the air polluted state in the breeding room, because the environment is prone to the developmental disorders caused by the air propagation of the disease and odor is used to deodorant.

In addition, the environmental temperature and breeding conditions required according to the purpose of the study or the type of laboratory animals should be different, but the existing breeding barrel is not equipped with a device for controlling this, the temperature of the entire breeding room is bound to maintain the same conditions.

Therefore, it is necessary to use a separate breeding room, respectively, if necessary, the energy cost and management costs due to cooling, heating takes a lot of problems.

The present invention has been made to solve such a conventional problem, by automatically discharging the odor generated from the urine and feces during the breeding of experimental animals or pets in the breeding box to the outdoors to create a comfortable environment for indoors and receiving animals. The purpose is to provide.

Another object of the present invention is to be able to prevent disease transmission and the occurrence of odor in advance by allowing a plurality of breeding barrels to be built in the enclosure, and to separate the experimental animals into groups to breed in separate environments. .

Still another object of the present invention is to maintain the temperature and humidity in the breeding barrel at the most optimal state according to the type and season of the animal being accommodated.

According to an aspect of the present invention for achieving the above object, one side of the enclosure having an open inner space portion, opening and closing means for opening and closing the open portion of the enclosure, and installed in the inner space portion for accommodating small animals or medium animals A breeding barrel, a sewage tray detachably installed at the bottom of the breeding barrel to receive dirt generated from a small animal, and a ventilation hole formed between the flange of the waste tray and the bottom of the enclosure to discharge air in the enclosure to the outside; It is provided on the ventilation hole is provided with a small animal breeding cage comprising a ventilator for sucking air.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 to 7.

Figure 1 is an exploded perspective view showing a first embodiment of the present invention, Figure 2 is a longitudinal cross-sectional view of the coupled state of Figure 1 and Figure 3 is a perspective view showing a breeding barrel mounted in the enclosure, the present invention is open on one side and the inner space ( Opening and closing means for opening and closing the inner space portion is installed in the open portion of the housing 1 having a 1a) and the inner space portion (1a) is provided with a breeding barrel (2) for accommodating small animals or medium animals and the breeding barrel (2) At the bottom of the), a sewage receiver 3 for receiving dirt generated from a small animal or a medium animal is detachably installed.

1 and 2 illustrate a flange 2a of a breeding barrel 2 having a front surface open to the latching jaw 4 so as to protrude from the inner wall of the housing 1. ) Hanged and supported and the bottom surface of the breeding barrel is formed with a long through-hole (2b) in the longitudinal direction so that dirt generated from small animals or medium animals fall down through the through-hole (2b) or distribution hole (2c) The packing 6 for maintaining airtightness is fixed to the inner surface of the door 5, which is an opening and closing means for closing the front of the cage.

Therefore, as the fan 9 is driven, the air in the room is introduced into the air inlet 10-through-hole 2b or through-hole 2c-side of the flange 3a of the sewage receiver 3-ventilator 8-ventilator 9 Is discharged to outside.

However, in the case where several enclosures 1 are installed in the same place to accommodate a large number of small animals or medium animals, the enclosures 1 as shown in FIG. 4 and FIG. It is effective to use a combination of a plurality of) integrally in the longitudinal (up, down) direction and the transverse (left, right) direction.

However, depending on the conditions, the enclosure 1 of the first embodiment may be laminated and used only in the up and down directions.

4 is a longitudinal cross-sectional view showing a second embodiment in which a plurality of enclosures 1 are coupled as described above, and a breeding barrel 2 as shown in FIG. 3 in a locking jaw 4 provided on an inner wall of the enclosure 1. The flange (2a) is configured to be caught and supported, and the bottom of the housing (1) is detachably installed in the reservoir 3 and between the flange (3a) and the bottom of the housing 1 of the The ventilation opening 8 is provided.

The ventilation holes 8 formed in the respective enclosures 1 are connected to the connection pipes 14. In the case of a small scale, the ventilator 9 may be installed on the upper part of the enclosure 1, but in the case of a large scale, The fan 9 is installed in a separate machine room 15 provided on the side.

In addition, the control lever 19 is installed in the connection pipe 14 adjacent to the ventilation port 8 to adjust the amount of exhausting the polluted air.

5 is a longitudinal cross-sectional view of a second embodiment of the present invention in a stacked state, which is different from FIG. 4 except that the air inlet 10 of the door 5 is transparent to block external air as shown in FIG. 1. It is the point that the sealing with the material and the apparatus for artificially controlling the temperature and humidity in the enclosure 1 were added.

Accordingly, the pipe formed with a plurality of holes on the ceiling in the enclosure 1 is connected to the cold, hot air blower 16 and the water tank 17 through the cold, hot air supply pipe 18 to generate a negative pressure by the operation of the fan 9. When the air in the contaminated enclosure is exhausted through the ventilation hole 8 formed in the lower part of the enclosure 1, a negative pressure is formed in the enclosure 1.

Since the negative pressure is again transferred to the cold and hot air blowers 16 through the cold and hot air supply pipes 18, air having hot or cold air generated from the cold and hot air blowers is introduced into the enclosure 1 through the water tank 17. Only fresh air flows into the enclosure at all times.

If the indoor temperature is maintained at an appropriate temperature, the driving of the cold and hot air fans 16 is stopped, so that the inside of the enclosure 1 maintains the same temperature as the indoor temperature.

The cage (2) mounted in the housing (1) may have a different shape depending on the purpose of use, while the cage (1) as shown in Figure 1 is suitable for mooring a medium animal such as a dog or cat for a short period of time, such as rodents In the case of long-term breeding of experimental animals, it is preferable to use a breeding barrel as shown in FIG. 3.

The ventilator 9 and the cold and hot air blowers 16 installed in the enclosure 1 may be connected to the cold and hot air supply pipes 18 and the connecting pipes 14 to be installed at appropriate places according to the surrounding conditions. In the case of a kennel, the installation of the machine room 15 is installed outside, and the cold and hot air supply pipe 18 and the connection pipe 14 are buried in the facility, and the connection joints for connecting them to the required positions are more easily installed. Will be lost.

On the other hand, a myriad of distribution holes 2c are formed in the bottom surface or the circumferential surface of the breeding barrel 2 provided in the housing 1.

Like the breeding barrel 2 shown in the second embodiment, the distribution hole 2c may be formed over the entire bottom surface, or the distribution hole may be formed only on the circumferential surface, but a portion of the bottom surface of the breeding container 2 (about 2/3) may be formed only in the distribution hole 2c.

As such, the reason for forming the distribution hole only in a portion without forming the distribution hole 2c throughout the breeding barrel 2 is in the case of a relatively small rodent, such as a mouse, due to the wind passing through the distribution hole 2c. The sensory temperature of the mouse will be changed so that the mouse moves by itself to maintain the proper temperature.

That is, when the mouse is hot, the heat is cooled at the site where the distribution hole 2c is formed. On the contrary, when the mouse is cold, it is intended to sleep and rest at the site where the distribution hole is not formed.

6 and 7 illustrate a mesh-shaped panel 7 in which a small animal is placed on the locking jaw by protruding the locking jaw 4 on the inner wall of the housing 1. It is installed so that the panel serves as the bottom surface of the breeding barrel (2).

Ventilation openings 8 are formed between the flange 3a of the dust collector 3 installed in the lower part of the enclosure 1 and the bottom surface of the enclosure, thereby contaminating the contaminated air (odor) within the enclosure (1). A ventilator 9 for sucking air is provided on the ventilation port.

A flange 3a is formed in the waste holder 3 detachably installed at a lower portion of the breeding barrel 2 to receive waste generated from a small animal or a medium animal, as shown in FIG. It becomes smaller from the front to the front.

This is to distribute the negative pressure in the enclosure 1 generated by the driving of the fan 9 to the left and right flanges 3a so that the ventilation in the enclosure is evenly made so that fresh air always flows in the enclosure 1.

And in the first and second embodiments, the opening and closing means for opening and closing the opening of the enclosure 1 is a door 5 having an air inlet 10 for introducing air in the room into the interior of the enclosure 1 on the upper side of the enclosure ( Although it is installed to be opened and closed by the hinge 11 in the front of 1), and the fixing cover 12 is fixed to the upper side of the housing 1 as shown in Figs. The opening cover 13 may be configured to be opened and closed at one side of the fixing cover, and the door 5 may be installed to be opened and closed at the front of the housing 1.

However, when configured as in the third embodiment, it is more preferable that the fixing cover 12 and the opening cover 13 are all formed of a transparent material, or any one of them is formed of a transparent material.

This is because the small animals in the enclosure 1 can be visually identified without opening the opening cover 13.

In addition, as shown in FIGS. 4 and 5, the housing 1 configured as described above may be stacked in an up, down, left, and right direction to allow more small animals to be raised even in a small area. In this case, the respective enclosures 1 Although the connection pipe 14 may be connected to the ventilation hole 8 of the ventilator 8 and then discharged to the outside, if the mouse is a stress sensitive type or a large experimental animal breeding ground, the connection pipe 14 may be further extended to be installed outdoors. In the machine room 15, it is more preferable to provide a fan 9 for discharging the contaminated air in each enclosure 1 to the outside and a cold / hot air fan 16.

The reason why the fan 9 is installed in the machine room 15 of the outdoor unit is to prevent the small animal in the enclosure 1 from being stressed due to the noise and vibration generated by the operation of the fan.

In this case, as shown in FIG. 5 of the second embodiment, when the temperature in the room is low or high, ideally to improve the temperature and humidity in the enclosure 1, or more fresh air than the indoor air. In this case, and when different temperature conditions are required in the same breeding room, it is preferable to install cold and hot air supply pipes 18 connected to the cold, hot air blower 16 and the water tank 17 on the opposite side of the ventilation opening 8. More preferred.

This is because the temperature and humidity in the enclosure 1 can be appropriately adjusted according to the small animal or the medium animal being bred.

In addition, on the connecting pipe 14 and the cold, hot air supply pipe 18, the control levers 19, 20 for controlling the amount of exhaust air discharged from the housing 1 and the inflow of cold and hot air are respectively installed. It is.

This is because the suction bin and the blowing force generated from the place where the cage 2 is installed, that is, the fan 9 and the cold and hot air fans 16 are respectively varied according to the position of the cage 2, so that the degree of sound pressure is different. This is to control the sound pressure in the enclosure 1 by operating the control levers 19 and 20 according to the position of (2).

Meanwhile, even in the third embodiment, an air inlet 10 is formed between the housing 1 and the fixed cover 12, and the air inlet pipe introduces indoor air into the interior of the enclosure 1 at the air inlet. (21) is connected, the heater 22 and the water tank 23 is installed on the air inlet 10 to properly maintain the temperature and humidity in the enclosure (1), the interior of the enclosure (1) The temperature sensor (not shown) which senses the temperature in the enclosure and controls the drive of the heater 22 is provided.

Referring to the operation of the present invention configured as described above is as follows.

First, the present invention configured as described above can be used in a laboratory or a laboratory, and in a large-scale breeding facility, a breeding cage of the form as shown in FIG. 2 is stacked in the top, bottom, left, and right as shown in FIGS. In the case of the first and second embodiments, when the flange (2a) of the breeding barrel (2) is seated on the locking jaw (4) formed in the inner space of the housing (1), the flange is locking jaw (4) Since it is in close contact with the packing 24 located on the upper surface of the airtight between them is maintained.

However, in the third embodiment, the panel 6 serves as the bottom surface of the breeding barrel, and the fixing cover 12 and the opening cover 13 serve as the top surface. In the third embodiment, small animals such as dogs and cats Since it is very useful for continuous observation or treatment (injection, drug administration, etc.) due to illness and hospitalization, it is not necessary to lay a rug on the upper surface of the panel 7. In the first and second embodiments, In the case of using the rectangular barrel-shaped breeding barrel (2) in the catching jaw (4), because the small animals such as mice or hamster breeding should be laid on the floor.

Accordingly, in the case of the first and second embodiments, the door 5 is opened, and then a pet such as a dog or a cat or an experimental animal such as a mouse or a hamster is inserted into the breeding barrel 2, and then the door 5 is closed. In the case of the third embodiment, the opening cover 13 in which the small animal is put into a diseased dog or cat inside the enclosure 1 while the opening cover 13 is opened is closed.

In this way, when feces are generated from the small animals while the small animals are put into the housing 1, the generated feces are accumulated by free fall to the sewage container 3 located below the breeding container 2, and the feces are accumulated at this time. Most are dried.

When the amount of feces accumulated in the sewage collection 3 increases, the manager may collect the feces while the door 5 installed in the front of the enclosure 1 is opened.

However, in the case of the cages of the first and second embodiments, when urine generated from a small animal is repeatedly absorbed by the rug laid in the breeding barrel 2, severe odor is generated from the urine. Of course, it contaminates the whole building, but the device of the present invention makes it possible to completely remove these odors.

As described above, the odor generated during the breeding of the small animal is introduced into the interior of the enclosure 1 by the operation of the ventilator 9 installed on the ventilation port 8, and together with the contaminated air in the enclosure. Because it is discharged to the outside through 8), the odor does not come out indoors, and therefore no odor is emitted indoors.

At this time, the odor and gas generated in the urine and feces on the rug is discharged to the outside through the air inlet 8 with the polluted air, so the odor does not come out of the room unless the fan 9 is turned off.

In addition, since the fresh air of the same amount as the amount of air discharged by the forced ventilation is introduced into the inside of the housing 1 inside the housing 1, only the fresh air flowing at a constant speed is always present inside the cage. It is possible to keep the interior in a comfortable state.

At this time, by operating the control lever 19 installed on the connecting pipe 14 to maintain a constant sound pressure inside the housing 1, or by adjusting the rotational speed of the fan installed in the fan (9) the most comfortable to the animal Ventilation can be achieved at a ventilation speed (0.2-0.4 m / sec) to maintain the environment.

On the other hand, as in the second embodiment, the cold, hot air blower 16 and the water tank 17 are connected to the cold, hot air supply pipe 18 in the housing 1, or on the air inlet 10 as in the third embodiment When the heater 22 and the water tank 17 are installed, it is possible to maintain the temperature and humidity in the enclosure (1) in an appropriate state according to the health of the small animal in the breeding or the temperature and humidity in the enclosure (1) Or it can be understood that the animal can be reared in a more comfortable state.

As described above, the present invention has the following advantages over the conventional breeding barrel.

First, it has a function to clean odor, ammonia gas and excretion generated from urine and feces that animals excrete, so that small animals in the breeding can always drink fresh air in a pleasant environment, so the small animals are in a healthy state. It becomes the maintenance.

Second, since the inside of each enclosure independently ventilate as well as the discharge function of urine and feces, it is possible to prevent disease transmission between individuals due to group breeding in the same place breeding facility.

Third, when the housing is stacked up and down, it is economical because it can accommodate a variety of small animals at the same time, but can be managed in different conditions for different breeding barrels according to the purpose, significantly reducing facility management costs.

Fourth, because the odor generated in the breeding barrel is always air flows in a constant direction, the urine and feces are quickly dried, which can significantly reduce the cost of labor and deodorant for the odor generation suppressed by the most manpower.
