20090188440 | LICK DETERRENT TUBING - A deterrent apparatus having a non-conductive tubing having a length, an outer surface and an inner surface defining a lumen, and at least a first electrical conductor and a second electrical conductor present on the outer surface of the non-conductive tubing. A power source comprising a battery having a first terminal and a second terminal is connected to the conductors so that the first terminal is electrically connected to the first conductor and the second terminal is electrically connected to the second conductor. The deterrent apparatus is suitable for use on medical tubing or veterinary tubing, for example, to deter animals from chewing or biting at the tubing. | 07-30-2009 |
20090188443 | VETERINARY MEDICAL TUBING REMOVAL DETERRENT TECHNOLOGY - An apparatus and method for discouraging or deterring animals from removing or attempting to remove veterinary medical lines which are attached to them or otherwise located in their immediate vicinity. The apparatus includes a tube body, two electrical conductors connected to the tube body in a spiral, wrapped configuration, and a battery power source. The tube is constructed of a non-conductive material and may be of varying diameter and length. The conductors are disposed so that they may be contacted on the outside of the tube body, and upon contact with the animal's tongue or saliva, an electrical circuit is completed through the tongue, conductors and power source, thereby delivering an electrical impulse through the sensitive tissues of the animal. The low voltage electrical shock is harmless to the animal but is unpleasant, thus the animal does not attempt to remove the intravenous tube and medicating proceeds as normal. | 07-30-2009 |
