DETAILED DESCRIPTION OF THE INVENTION
[0039] A prior art poultice sheet 100 of bi-laminar quilted fibre paper for applying around a horse's leg is shown in
[0040] Referring now to
[0041] The poultice layer 24 comprises a conventional mud/clay poultice mixture, which mixture may, as discussed above, include kaolin (white clay) and/or bentonite (clays made from volcanic ash) and may additionally comprise, in lesser amounts, various known medicinal and non-medicinal ingredients such as Epsom salt (magnesium sulfate) thought to assist in lessening infection, muscle and tendon swelling and the like, emulsifiers such as guar gum for maintaining the texture of the poultice mixture, together with other known bacteriostatic and mold inhibiting agents for improving the shelf life of the poultice mixture, such as, for example, borax. As previously mentioned, one such commercially-available poultice suitable for use in the poultice layer 24, according to the present invention is the Uptite® poultice mixture offered by Wecan Sales Ltd. (of Beamsville, Ontario, Canada).
[0042] The backing sheet 32, as seen in
[0043] Alternatively, the backing sheet 32 may be constructed from a woven fabric material, such as, for example cheesecloth, burlap, gauze and gauze-like cotton cloth. As such, the backing sheet 32 supports and holds the form of the poultice layer 24, and also assists in preventing the poultice mixture from drying out prematurely during the period of 12 to 15 hours during which it is typically applied to the leg of the animal being treated.
[0044] By supporting and holding the form of the poultice layer 24 during application of the poultice mixture to the treatment area, the backing sheet 32 is instrumental in containing the poultice mixture proximate to the application area during the application process, thereby significantly reducing the mess and waste caused by poultice mixture that is displaced beyond the treatment area during conventional poultice application procedures.
[0045] As seen before use in
[0046] The adhesion-resistant release sheet 28 may be constructed from a paper material, such as, for example, butcher's paper (shiny side down), parchment paper, wax paper, or plastic coated paper. Preferably, the release sheet 28 is constructed from a adhesion-resistant plastic material, such as vinyl, polyethylene or polypropylene, so as to retain moisture in the poultice layer 24 during transport and storage and so as to resist sticking of the release sheet to the first side 24a of the poultice layer 24 when the release sheet 28 is torn away from the poultice layer 24 by the user prior to application of the pad 20 to the treatment area.
[0047] As seen in the embodiment of
[0048] The adhesion-resistant release sheet 28 and the backing sheet 32 are each preferably dimensioned slightly larger than the width and length of the poultice layer 24, and preferably overlap around all edges of the perimeter of the poultice layer 24 to preferably touch each other as shown in
[0049] While prior art poultice mixtures typically have a very sticky, paste-like consistency which allows them to advantageously adhere to the hair and skin of the animal to be treated, it is this same consistency that, less advantageously, makes them stick to most other materials they may come in contact with during the poultice application process, such that cleanup of errant poultice mixture can becomes extremely onerous when poultice mixture is displaced beyond the treatment area of the animal. Thus, use of a backing sheet 32 that adheres to and holds the form of the poultice layer 24 on the backing sheet 32 during application of the pad 20 to the treatment area of the animal significantly lessens transfer of poultice mixture beyond the application area, thereby significantly simplifying and shortening cleanup time over conventional poultice application procedures.
[0050] The present invention also significantly simplifies and shortens the time required for a user to carry out the first step of the conventional poultice application process described above, in which conventional first step the user is required to hand pack a layer of poultice mixture onto the leg of the animal by repeatedly scooping of handfuls of the poultice mixture from the bulk containers in which it comes packaged and thereafter smoothing it over the leg of the animal until an acceptable thickness of poultice mixture had been applied to the treatment area. As the optimal quantity of poultice mixture and its thickness is pre-determined during the manufacture of applicant's poultice application pads 20, the present invention not only simplifies this first step of the process by eliminating the trial-and error guesswork required by said first step of the conventional art poultice application process, but also saves time by immediately delivering an appropriate measured amount of poultice mixture in a substantially uniform thickness to the treatment area of the animal coincident with the action of wrapping the poultice application pad 20′ around the leg of the animal by a user.
[0051] In use, when a poultice is to be applied to a horse's leg according to the present invention, a poultice application pad 20 is retrieved and the adhesion-resistant release sheet 28, (where optionally present), is removed by peeling it away from contact with the poultice layer 24. In this manner, the generally planar first surface 24a of the poultice layer 24 is exposed. The poultice application pad 20 is then applied, poultice layer 24 first, to the area of the horse's leg to be treated, wrapping it therearound with the backing sheet 32 holding the poultice layer 24 in place on the leg of the horse. The exposed poultice layer 24 will stick and adhere to the horse's leg upon contact. Then, without necessarily needing rubber gloves, the user may preferably press on the backing sheet 32 of the poultice application pad 20 to mold it and the poultice layer 24 to substantially every contour and groove of the horse's leg. No added water is required and there will typically be little or no mess or waste caused by displacement of the poultice material beyond the treatment area. Moreover, the poultice application pad 20 may adhere to the horse's leg without needing to be held in place by hand, such that, with her or his hands free, a user may even choose to apply all four poultice application pads 20, one to each of the horse's legs, before proceeding with any secondary bandage wraps. A secondary bandage wrap (e.g., a standing bandage) may then be applied around the horse poultice application pad 20 to hold it in place about the area of the horse's leg being treated.
[0052] A standing bandage wrap, or stable bandage wrap, is a type of prior art wrap used on the lower legs of a horse. Prior art leg bandage wraps of this type are usually started on the outside of the horse's leg, in the middle of the cannon bone, then wrapped down to the fetlock, then back up to just under the knee, then back to the center of the cannon just above the starting point, ending on the outside of the leg. Most of the time, legs have been wrapped starting on the outside, moving front to back. Such bandage wraps either may be disposable stretchable wrap that sticks to itself, or washable fleece or cotton wraps that are reusable and fasten at the ends with a hook and loop closure or other fasteners. Bandages of this sort may also be taped with medical tape to help them stay on. In this manner, the stable bandage may be used to secure the equine poultice application pad 20—i.e., to hold the equine poultice application pad 20 in place on the lower legs of the animal being treated.
[0053] According to other embodiments of the invention, one or more poultice application pads according to the invention may be held either individually, or in a stack, within a container in sealed relation from atmosphere (i.e., in an airtight container) to physically protect the application pads from damage during shipment and/or storage, and to maintain the desired level of moisture within the poultice application pad over extended periods of time following initial manufacture and packaging. Preferably, the container in each of these embodiments is made from an adhesion-resistant plastic material, such as vinyl, polypropylene or polyethylene, so as to provide for non-stick removal of the poultice application pads from the container. The container may be rigid in the form of a tub or the like, with a removable, re-sealable lid, or may be a flexible tear-open foil or plastic film pouch. Most preferably, the container is vacuum sealed at the factory to maintain the level of moisture within the poultice mixture within close tolerances over an extended period of time so as to extend the shelf-life of the poultice application pads packaged therein. While the poultice application pads for some applications may be packaged individually according to this aspect of the invention, preferably, the container is sized and otherwise adapted to hold a stack of four poultice application pads, one for each limb of a quadruped animal, such as a horse.

[0064] In the various manners described above, a horse's hooves and one or more, and preferably all four, of a horse's legs may be routinely provided with poultices to treat and prevent swelling and soreness and to aid in healing. Use of the present invention may preferably obviate any need to manually apply poultices in the manner of the prior art, and to reduce the amount of time, mess, and waste of materials which otherwise may be involved when poultices are applied to the legs of a horse. The present invention preferably facilitates and readily provides for a thick, even, direct and consistent application and compression of an appropriate amount of poultice mixture against the legs of an animal, most notably to a horse's legs. The exposed poultice layer of the present invention preferably sticks and adheres to the horse's leg upon contact. The present invention preferably does away with any need for gloves (or added water), and minimizes mess and waste, while affording users with an ability mold the poultice application pad to substantially every contour and groove of the horse's leg or hoof. The present invention preferably frees up a user's hands and even affords an ability to apply all four poultice application pads, one to each of the horse's legs, before proceeding with any secondary bandage wraps. Accordingly, the present invention preferably provides improved equine poultice application pads, and an improved method of applying poultice to a limb of an animal, such as a horse. The equine poultice application pads or wraps of the present invention preferably do not suffer from one or more of the disadvantages which may have been associated with the prior art. Accordingly, the present invention preferably solves, obviates or mitigates one or more problems, disadvantages or shortcomings associated with the prior art, or meets or provides for one or more needs or advantages.
[0065] Notwithstanding the above description in association with horses, persons skilled in the art should readily appreciate (in view of the disclosures herein) that the above described equine poultice application pads 20, 20′, 20″, and 20′″ can be readily adapted for use on any animal.
[0066] Other modifications and alterations may be used in the design and manufacture of other embodiments according to the present invention without departing from the spirit and scope of the invention, which is limited only by the accompanying claims.
