Detailed Description of the Invention Embodiments of the present invention feature devices and methods for administering a medicament to an animal or human. These embodiments will be described in detail as a device and method for administering molecular iodine to an animal, such as a dog, for the treatment of bad oral breath and preventing plaque formation. Those skilled in the art will recognize that embodiments of the present invention have application for the treatment of human disease and other animal and other diseases. The embodiments described are the best mode of the invention as presently contemplated. However, embodiments of the present invention can be modified and altered and the descriptions herein should not be considered limiting.
Turning now to Figure 1, a device, embodying features of the present invention, is designated with the numeral 11. The device 11 is for administering a medicament, molecular iodine, for the prevention or treatment of a disease, bad oral breath in a dog [not shown in Figure 11. The device 11 comprises a source of medicament in a fluid 13, measuring means 15, an administration switch 17 and a water reservoir means 19, held in a housing 21.
The source of medicament 13 comprises a vessel containing molecular iodine in an ethanol solution. The molecular iodine is added to the water reservoir means 19 as an absolute

6 alcohol solution saturated with 12. An effective amount of this solution is formed with 1.0 to 0.001 ml, more preferably, 0.1 to 0.025 ml, to about 0.05m1. This effective amount in about 500 ml of water forms, if consumed by the animal is no more than about 250 to micrograms of iodine daily, an amount that is safe and effective for thyroid function and an amount that substantially disinfects the oral cavity of an animal.
Sources of medicament 13 may take several forms, such as without limitation, tanks, conduits, pumps, bags, pouches, cartridges, vials, bottles, syringes and pressurized cans. Embodiments featuring a tank may incorporate the tank as an integral vessel that receives external fluid containing medicaments. Or, a vessel can be a replaceable consumable which is fitted to, or constructed and arranged to cooperate with conduits and/or pumps to communicate with measuring means. Pressurized cans and containers may not need pumps and use compressed air to propel the medicament. Although reference is made to pumps or pressurized vessels, the fluid may move from the source of medicament 13 to the measuring means 15 by gravity feed without pressure and without pumps. For the purpose of this description, the source of medicament is a glass vessel containing ethanol saturated with molecular iodine.
The measuring means 15 is in fluid communication with the source of medicament 13 for measuring an aliquot of medicament corresponding to a dose for the prevention of plaque or treatment of a disease. As used herein, the temi in "fluid communication"
means plumbed together, or receiving fluid from one to the other. The measuring means 15 is also in communication with a water reservoir means and releases the aliquot into the water reservoir means 19 upon signal activation. The measuring means 15 comprises a timed or measured valve or pump, or metering syringe, or emptying a measuring vessel. For example, without limitation, where the medicament is held in a pressurized can, the measuring means may take the form of a dispensing valve not shown] known in the art of the type used for dispensing aerosols and fluids. See for example: Remington: The Science and Practice of Pharmacy, 20th Edition. Lippincott Williams and Wilkins (2000) at 976-978. As depicted and described herein, the measuring means is a timed pump plumbed to the source of medicament 13 via medicament conduit 33a.
The administration switch means 17 is in signal communication with the measuring means 15.
Upon activation by a subject, such as a human or animal, administration switch means 17 produces an activation signal received by the measuring means 15.

7 As best seen in Figure 2 which depicts signal communication of device 11, administration switch means 17 has an on/off switch 23 for an electrical circuit 25 which operates measuring means 17 in the fonn of a pump [not shown] and a purge means 51 to be described more fully below. In the alternative, the administration switch means operates a motor or solenoid [not shown] with a mechanical link to a valve, measuring vessel, timed pump, metering syringe [not shown]. The switch 23 is further in signal communication with a CPU 31 which has timing functions and scheduling programming. The timing function times the power to the pump or solenoid such that the pump, valve, measuring vessel or metered syringe dispenses a desired dose of medicament in the water reservoir means 19. The scheduling function will dispense medicament at selected times of the day and for individual subjects from a population of potential subjects.
The administration switch means 17 of Figure 1 and Figure 2 further comprises a photometric or electromagnetic sensor which detects the presence of the subject. For example, without limitation, one embodiment of the present invention comprises a camera [not shown] and CPU, such as CPU 31, with visual recognition software for detecting the presence of an animal. As illustrated in Figure 1 and 2, the photometric or electromagnetic sensor detects the presence of a tag 37. The tag 37 is recognized by sensor 39 by virtue of bar coding or other optical or electromagnetic coding. For example, one embodiment of the present invention features a sensor such as an optical scanner.
One embodiment, as illustrated, is an REID tag 37. RFID tags are available from numerous vendors. A plurality of RFID tags 37, each coded separately for a plurality of individual subjects, are used to administer medicaments to selected or identified subjects from a population of potential subjects, at selected times or to receive selected medicaments. Tags and sensors which can detect a subject from a population of potential subjects are used in embodiments of the present invention to denote an identified subject or identified animal.
Different tags having different codes are used to denote one of more identified animals from the potential population or separate identified animals for different medicaments or doses.
Although a CPU 31 is depicted in Figure 2, control means can comprise other analog and digital equipment which receives signals from the sensor and in response to the signal issues an activation signal to measuring means 15. Embodiments of the present invention feature

8 administrative switching means 17 having control means in the folin of computer processing units (CPUs) integrated into a device 11. However, CPU 31 may be located apart from the device 11, as a separate computers, server, personal computers, internet linked computers and the like, in signal communication with measuring means 15 by means of wired or wireless communication devices.
Embodiments of the present invention feature control means such as CPU 31 having memory to store information regarding selected subjects and the administration of medicaments. Such memory is known in the art and is not shown for purposes of clarity.
Embodiments further comprise timing elements or clock functions and programming to administer medicament in accordance with a schedule. Clock functions are common in CPU
systems supporting CPU 31. Scheduling programming is also well known in the art. One embodiment of the present invention features molecular iodine administered to a selected subject or animal a schedule of once or twice daily. The doses are separated in time, for example eight to twelve hours. Programming is facilitated with a display screen 41 and controls 43 as best seen in Figure 1.
The water reservoir means 19 is for receiving the aliquot and forming an aqueous solution of medicament. Water reservoir means 19 comprises a space constructed and arranged to receive a sized or shaped fluid receptacle, a fluid receptacle integral with the device or a disposable or removable cup, feeding and/or watering bowl or glass. As best seen in Figure 1, the water reservoir means, as depicted, is integral with the device 19 and comprises a basin 45 for holding a suitable amount of water, for example 100 to 800 ml. Water reservoir means 19 has a volume sensor 47 that detects when the basin 45 is at capacity or empty.
The volume sensor 47 is in signal communication with CPU 31 which coordinates the administration switch means 17 and measuring means 15 such that medicament is not added to the basin 45 when basin 45 can not accommodate additional fluid or when the addition of medicament would not lead to an appropriate dilution.
Water reservoir means 19 is in fluid communication with a source of water 71, best seen in Figure 3 which depicts a fluid diagram of device 11. The flow of which is controlled by a valve or siphon mechanism not shown] known in the art and under signal control of the

9 volume sensor 47 and CPU 31 or under hydrodynamic-mechanical control. Water flows into basin 45 via water inlet 67.
As depicted in Figure 1, the device 11 further comprises purge means 51 in communication with the water reservoir means 19. Purge means 51 removes medicament from the basin 45.
As depicted, purge means 51 comprises a drain 53, purge filter 55, purge conduits 57a-c, pump 59 and purge outlet 61. Liquid is removed from the basin 45 through drain 53 and conveyed by purge conduits 57a-c to a purge filter 55, purge pump 59 and on to the purge outlet 61. Thus, water is cleaned and medicament removed and reintroduced into the basin 45.
Purge filter 55 is made of porous materials to remove hair, dust and dirt.
Purge filter 55 has an activated charcoal bed to remove medicament. Removal of medicament may be advantageous where the device 11 is used in the presence of small children.
Purge means 51 may also comprise waste receptacles [not shown] for storing a volume of water. Removal of the water may obviate the need for a purge filter 55. Purge means 51 can be constant or switched by a purge switch not shown] which directs the liquids in the water reservoir means to adsorption materials or into the waste reservoir. For example, the purge pump 59 of purge means 51 is in signal communication with a purge switch means not shown] and is actuated by a purge signal. The purge switch means comprises a timed electrical or timed mechanical switch that is coordinated with the administration switch means 17, or separate or combined with administration switch means 17, including incorporation of programming in control means such as a CPU 31. For example, without limitation, one control means is programmed to issue a purge signal after an animal leaves the water reservoir.
The present device 11 is plumbed with a source of water 71 shown in Figure 3 which communicates with the basin 45 through a water inlet 67. Water inlet 67 releases water to fill basin 45 under the control of water level sensor 47 and CPU 31 or mechanical hydrodynamic means not shown] known in the art.
Embodiments of the present invention directed to a method for administering a medicament to an animal will he described in detail with respect to Figure 1 and device 11.
The method comprising the steps of providing a device 11 having a source of medicament in a fluid 13, measuring means 15, an administration switch 17, and water reservoir means 19 as previously described. A subject, such as a house pet, is fitted with a tag 37. As the subject approaches the water reservoir means 19, the tag 37 is recognized by administration switch means 17 and 5 measuring means 15 is activated with an administration signal to dispense a dose of medicament such as molecular iodine. Administration switch means 17 recognizes the time the subject leaves the water reservoir means 19, and CPU 31 issues a purge signal to purge means 51 to remove medicament form the water reservoir means 19.

10 Embodiments of the present method are well suited for the administration of molecular iodine to the oral cavity of a subject such as a human or an animal. One medicament is a saturated iodine in ethanol comprising iodine crystals and absolute ethanol. In the alternative a 10%
solution is prepared by dissolving 1 gram of iodine crystals in 100 ml of absolute ethanol. A
1% solution is prepared from al :10 dilution of the 10% solution of iodine in absolute ethanol.
Examples Two dogs and two cats were administered molecular iodine at doses ranging from mcg iodine per day for one day and 1-5 mcg per day for three weeks with no ill effects.
Thus, we have described embodiments of the present invention with respect to the best mode presently contemplated with the understanding that the present embodiments can be altered and modified. Therefore, the present invention should not be limited to the discussion and figures described but should encompass the subject matter of the claims that follow and their equivalents.
