Description
SUBPALPEBRAL LAVAGE CATHETER DEVICE 2015264814 06M2017
Field 5 The present disclosure relates to catheter devices in general. The present disclosure pertains especially, but not exclusively, to an improved device to protect the injection port of a subpalpebral lavage catheter tube of the type used on a horse.
Background 10
Horses sometimes require medicines to be applied to their eyes to treat any one or more of a number of ailments. The treatment can occur several times a day and extend over a period of several days or weeks. Often, a horse will object to the intrusion of the eye by a veterinarian or owner, and can respond with violent or other erratic 15 behavior. For the safety of the owner and the horse, a subpalpebral lavage system is sometimes employed to provide a way of remotely administering the medication to the horse's eye easily and efficiently. The subpalpebral lavage system is made from a flexible tube having two ends, the first end of which mounts a catheter which is passed through the upper eyelid into the upper conjunctival fomix (the space located between 2 0 the eyelid and the eye). Medication is introduced to the system through the second end of the tube at a second distant injection port and is delivered to the upper conjunctival fomix of the eye through the tubing with the assistance of air injected into the system to move the medication through the tubing to the eye. Upon reaching the end of the tubing in the upper conjunctival fomix, medication exits the system and runs over the eye. 25
According to present practice, the injection port at the second end of the tube is allowed to hang freely, or the owner may be instructed to tangle the injection port into the mane of the horse. These practices present a variety of problems, including the opportunity for portions of the tube to become caught by a tree branch or other 1 9249684 1 (GHMatters) P76953.AU.2 6/07/17 protrusion such as a board, nail, or bucket, and rip the injection port, the catheter, or portions of the tube out of position, causing pain to the animal and requiring reinsertion of the catheter or rearrangement of the tube. Another common problem is that the injection port becomes dirty or is otherwise contaminated by reason of the animal 5 rolling on the ground, which may require cleaning before its reuse, or worse, the dirt or other contaminate may travel through the tube to the injured eye so as to cause infection or introduce a fungus. 2015264814 06 Μ 2017
Other attempts have been made to address the problems referred to above with 10 other animals including cats, dogs, and mice. One such method is shown in U.S. Patent Application No. 2002/0128613 (“Nakayama”), where a somewhat constricting mesh wrap is used to hold the injection port to the back of a small animal such as a cat, dog or mouse. The mesh wrap of Nakayama is however not suited for use on a large animal, such as a horse, and is deemed to be impractical in general due to the natural objection 15 by animals to wearing such a constricting device. Further, the mesh wrap device of Nakayama permits its injection port to be trapped against the body of the animal which encourages contamination due to dirt and sweat being trapped between the wrap and the injection port, which in turn requires removal of the wrap and cleaning of the injection port. A similar item for a horse is known by the tradename Sleazy Sleepwear, however 20 it presents similar problems as described above, with reference to the Nakayama device.
Another attempt to protect the injection port of a medicating device, while not used with an eye catheter, is described in U.S. Patent No. 5,839,393 (“Rupp”). In this case, a hard plastic shell is employed to protect the injection port from being pulled 25 loose and moved against the animal’s body. However, the Rupp device does not keep the injection port clean. Further, use of a device such as the Rupp device is completely impractical on a large animal, since the animal's legs necessarily have to stick through openings in Rupp's hard plastic shell and risk damage. 30 ? 92496841 (GHMatters) P76953.AU.2 6/07/17
Summary 2015264814 06 Jul2017
An embodiment provides a device for protecting the injection port of a subpalpebral lavage system. The device comprises a pouch, which is sealed on all sides 5 except one.
The open side of the pouch mounts a closeable flap, which allows for insertion and removal of the injection port. The pouch has two or more loops attached to one of its sides and which are removably secured to the horse by braiding two or more of loops 10 through the mane hair of the animal.
The injection port of the catheter tube may be stored in the pouch when not in use, with the flap in its closed position, but in a maimer allowing for a small opening for the tube to pass through. When the medicine or wash is administered to the horse, the 15 flap may be unsecured and opened and the injection port is removed from the pouch. After administering the medicine or wash, the process may be reversed, keeping the injection port clean and protected between uses.
The foregoing and additional features and advantages will become further 2 0 apparent from the detailed description that follows. A further embodiment extends to a catheter protection device for a mammal comprising: 25 a. a hollow pouch, which is sealed on all sides except one, wherein the one side of the pouch forms an opening adapted to receive and enclose an injection port of a catheter; b. means for closing said opening of said pouch in a manner allowing for a small opening for a tube to pass through; and c. means for attaching said pouch to said mammal. 3 9249684 1 (GHMatters) P76953.AU.2 6/07/17

Brief Description of the Drawings 2015264814 06 Μ 2017
Embodiments will be described, by way of example only, with reference to the accompanying drawings in which: 5 Figure 1 is a side view of an embodiment as used on a horse;
Figure 2 is a side view of an embodiment dismounted from the horse with the pouch flap in the open position; and
Figure 3 is a side view of an embodiment with the pouch flap in the closed position and showing the tube passing through a small opening between the flap and the 10 pouch.
Detailed Description
Figure 1 is a side view of the pouch 10 as used on a horse 42 with the loops 20a, 15 20b, 20c braided into the mane 26 of the horse 42. The subpalpebral lavage catheter tube 14 enters the skin of the horse 16 behind the injured eye 18 and runs down the length of the neck 24 and ends at the injection port 12 contained inside the pouch 10. The catheter tube 14 is attached to the horse's head behind the eyelid by means of a piece of adhesive tape 22. 20
Figure 2 is a side view of the pouch 10, not attached to a horse, with the flap 30 in the open position, ready to receive the injection port 12 of the catheter tube 14. Longitudinally spaced loops 20a, 20b, 20c are attached to the side 11 of the pouch 10 for braiding into the horse's mane as shown in Figure 1. The length D of loops 20a, 20b, 2 5 20c and the spacings S-I, S-2 are selected and arranged so as to permit such braiding.
The hook 32 positioned as in Figure 2 is not connected to the ring 34 allowing the flap 30 to be open and free to accept the insertion and withdrawal of the injection port (shown in Figure 3). The length D of loops 20a, 20b, and 20c is approximately two inches in the example being used for reference. 30 5 9249684 1 (GHMatters) P76953.AU.2 6/07/17
Figure 3 is a side view of the pouch 10, not attached to a horse, with the flap 30 in the closed position. Loops 20a, 20b, 20c are attached to the side 11 of the pouch 10 for braiding into the horse's mane as shown in Figure 1. In Figure 3, the injection port 12 is shown inside the pouch and the catheter tube 14 as shown in Figure 3, runs to a 5 comer of the pouch 40, where the flap 30 folds, and tube 14 exits the pouch through a small opening 13. The hook is connected to the ring (not shown) that holds the flap securely in the closed position. 2015264814 06 Μ 2017
The illustrated pouch is formed from a canvas or other suitable resilient material 10 with a length L of approximately eight inches and a width W of approximately one and a half inches. The pouch 10 may be of any other suitable dimension large enough to receive a catheter injection port. Optionally it may be constructed with drainage holes, to eliminate the occasion that water or other liquid should inadvertently enter the pouch. The flap 30 is held in the closed position by the illustrated hook 32 and eye or ring 34 15 (also known as a "hook and eye"), but many other means may be employed such as Velcro™, a button and hole, toggle, zipper, or drawstring. The only restriction is that there must be at least a small opening at the closed end of the pouch 10 so as to enable the catheter tube to run from the injection port to the horse's neck area. 2 0 In the embodiment there are three loops attached to the pouch 10 for braiding into the horse's mane, but any number greater than one may be attached. The pouch 10 is ideally attached to a horse's mane, but if needed, the tail of the horse. While the animal being described here is a horse, the pouch 10 could also be used for any other animal with a catheter tube if the hair on the animal is long enough, the device could be 2 5 attached to the animal's hair by braiding or, alternatively, attached by means of bonding suture wings. Additionally, the pouch 10 could be used with any mammal, where the loops are braided into the hair of the mammal. If the mammal is a human, the pouch loops could be braided into the hair of the head of the human, or attached by means of suture wings. In the preferred embodiment, the catheter is a subpalpebral lavage 6 9249684J (GHMatters) P76953.AU.2 6/07/17 catheter, however any suitable catheter device may be employed, and further, the catheter may be of any type known in the art. 2015264814 06 Μ 2017
In an alternative embodiment, the pouch has a plurality of extensions of a 5 material similar to that of the loops, except the extension is only attached to the pouch at a first end, instead of looping around to attach to the pouch at a second end. These extensions are removably secured to the hair of the mammal with rubber bands or other suitable device. 10 In an alternative embodiment, the pouch has a plurality of suture wings, as are known in the art, to removably attach the pouch to the skin of a mammal.
While the invention has been described with regards to specific embodiments, those skilled in the art will recognize that changes can be made in form and detail 15 without departing from the spirit and scope of the invention. This invention is limited only insofar as it is defined by the following claims and includes within its scope all equivalents thereof.
It is to be understood that, if any prior art publication is referred to herein, such 2 0 reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country.
In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary 2 5 implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention. 7 92496841 (GHMatters) P76953.AU.2 6/07/17
