Abstract: A non-choking pet restraint which applies restraining pressure to an animals shoulder's and chest and not to the neck and throat area. The device has a chest/belly panel, which also serves as a brush protective guard for dogs in the field, and two shoulder panels attached to it and to a back strap. Flank straps attach to the chest/belly panel, and to a back strap. A leach attachment ring is part of the back strap. The leash attachment ring rests on a dog behind his shoulder blades and rib cage, and in front of his hips. The device includes a convenient way to restrain a pet in a car seat using the car seat belt.

Abstract: A multichannel, multipurpose sample collection and drug delivery system for freely-moving laboratory animals includes several sampling and/or infusion devices mounted on a powered turntable above the cage but out of the animal's sight. Rotation of the tether as the animal moves is detected by magnetic switches, which cause the turntable to turn in the direction taken by the animal. Fluid or electrical swivels are entirely eliminated; the animal experiences almost zero torque on the tether. As the swivel normally limits the number of fluid or electrical connections in traditional systems, eliminating the swivel removes this constraint. Multiple probes can now be placed in alert, freely moving animals to sample several brain regions simultaneously.

Abstract: A tether system for an animal. The tether system has an apparatus which is electrically or fluidically powered or monitored with greater than 200 milliamps of current. The tether system is also comprised of an area for the animal and a structure above the area. The tether system is comprised of an anchor for attachment to the structure. The tether system is also comprised of a mechanism for providing power to the apparatus to operate it. The providing mechanism is in electrical communication with the anchor and the apparatus. The anchor prevents entanglement of the power providing means or mechanism as the animal moves freely about the area. Preferably, the tether system also includes a mechanism for providing fluid to or from the animal. The fluid providing mechanism is fluidically connected to the anchor and the patient. Additionally, the tether system can include a mechanism for transmitting electrical signals from the animal.
