The present invention generally relates to devices for stunning or euthanizing livestock. In particular, the present invention is directed to a Portable Controlled Atmospheric Stunning Device.
There are many techniques for euthanizing animals, including domesticated animals, other livestock, and pests. Some of these techniques include the use of a gas, such as carbon dioxide, to cause the animals to become unconscious and/or euthanized. This is typically accomplished by placing a group of animals into a large chamber and filling it with carbon dioxide gas. There is a need for an improved technique that uses a gas.
In an embodiment, a portable system for stunning an animal is provided that includes a canister containing carbon dioxide gas, the canister sized to be attached to a user, a hose having a first end and a second end, the hose being connected at the first end to the canister, and a hand-held hood connected to the hose at the second end of the hose, the hood including a handle, a chamber sized and configured to accommodate a head of the animal, an on/off switch, a closed end, an open end, and a flexible gasket substantially covering the open end. Upon actuation of the on/off switch, carbon dioxide gas is released into the chamber.
In an embodiment, a system for stunning an animal is provided that includes a canister for holding a gas that is sized to be carried by an operator of the system, a hose having a first end and a second end, the nose being connected at the first end to the canister, and a hand-held hood connected to the hose at the second end of the hose. The hand-held hood includes a handle, a chamber sized and configured to accommodate a head of the animal, an on/off switch, a closed end, an open end, and a flexible gasket substantially covering the open end. The flexible gasket includes a slit for allowing passage of the head of the animal into the chamber while allowing a sufficient amount of the gas to be retained in the chamber to stun the animal.
For the purpose of illustrating the invention, the drawings show aspects of one or more embodiments of the invention. However, it should be understood that the present invention is not limited to the precise arrangements and instrumentalities shown in the drawings, wherein:
A portable device of the present invention includes a hood encompassing a chamber with an opening on one end. The opening is covered by a flexible gasket with a slit. The chamber is connected to a carbon dioxide source (e.g., a canister worn on an operator's belt), which can be used to fill the chamber by an actuator for regulating the flow of the gas. In operation, the head of the animal is inserted through the slit into the chamber and carbon dioxide gas is directed into the chamber.
A portable stunning system for animals is provided that includes a hand-held chamber or hood into which an animal's head is inserted and then a gas, such as carbon dioxide, flows into the chamber. As used herein, “portable” means that the system can be carried and used by an individual operator without the need to use a transportation device or cart, and “hand-held” means the hood can be held in and manipulated by one hand of an average adult. The hood includes a flexible gasket or covering with a slit on one end, which allows the head of an animal to be placed into the hood while much of the carbon dioxide gas is still retained in the chamber. The hood includes a handle and may have a trigger or other mechanism to control the flow of carbon dioxide gas, which is stored in a tank strapped to the operator and connected to the hood via a hose or tubing. In this way, the system allows animals to be humanely stunned or euthanized individually with carbon dioxide gas using a hand-held, portable system that can be carried and controlled by an individual operator.
Turning to the figures, and in particular to
As shown in
Open end 132 of hood 116 is covered by flexible gasket 140, which, as can be seen in
In operation, an operator attaches canister 104 to a belt or otherwise carries canister 104. Regulator 108 is actuated to allow for the flow of gas out of canister 104 and the operator grasps handle 124 with one hand. The user then places open end 132 of hood 116 over the head of an animal to be stunned, with the animal's head passing into the chamber through gasket 140 via slit 144, which then tends to form a rough seal around the neck of the animal. The operator then activates on/off switch 120, which causes the chamber of hood 116 to substantially be filled with carbon dioxide gas. In a preferred embodiment under typical conditions, about 30 seconds is required to render a small animal unconscious, with an additional 20-30 seconds required before such an animal would be euthanized depending on the animal (e.g., a turkey). Poultry birds, for example, typically do not struggle under these circumstances, making the process simpler for the user and resulting in a calmer barn, cage, or other environment where the animals are housed. Once the process is completed, on/offswitch 120 is deactivated to stop the flow of carbon dioxide gas into the chamber of hood 116, and hood 116 is removed from over the head of the animal. The operator can then move on to the next animal without having to move the animals to a new location or to relocate heavy equipment.
Exemplary embodiments have been disclosed above and illustrated in the accompanying drawings. It will be understood by those skilled in the art that various changes, omissions, and additions may be made to that which is specifically disclosed herein without departing from the spirit and scope of the present invention.
