Description
SELF-CURING ORTHOPEDIC SPLINT AND METHOD FOR APPLYING SAME
FIELD OF THE INVENTION [0001] The present invention relates generally to the field of orthopedic medicine and more specifically to a novel orthopedic splint including a self-curing waterless bandage adapted to be applied to an injured limb for purpose of immobilization, and water laden gel for purpose of curing the splint material.
BACKGROUND OF THE INVENTION [0002] Conventionally, medical bandages and splints are used to immobilize broken bones. Generally, said splints are made of strips of plaster of Paris or fiberglass impregnated with water curable substance which hardens into a rigid structure once it makes contact with water. However, this procedure is cumbersome, messy and causes the splint to become wet. Furthermore, water may not be readily available in remote areas. Moreover, when the splint is applied to broken skin or an open wound, it represents a risk of infection since the water used to soak the material is non-sterile.
SUMMARY OF THE INVENTION [0003] The orthopedic splint system of this invention comprises a tear resistant outer bag and an inner envelop or protective sleeve containing a number of juxtaposed layers of orthopedic splint material impregnated with water curable resin commonly used in the orthopedic art. Said splint material can be fiberglass, polyester, nylon or plaster of Paris Water or water-laden gel is supplied separately and packaged as an integral part of ( i the self-curing splint system. Said water or water-laden gel is supplied in a long pouch inserted between the layers of the splint. The liquid pouch having a portion at one end containing no liquid and forming an extension of the pouch.
[0004] The extension is split into three sections where the middle section is flipped over and laid over the pouch. The outer two sections are positioned toward the opposite end of the liquid pouch and will be used to anchor the liquid pouch to the protective sleeve. The liquid pouch as described above is sandwiched between the layers of the splint material. The splint material and the liquid pouch are placed inside the protective pouch. Said protective pouch can be made out of non-woven material coated with a thin film of silicone or similar plastic material which render it air and moisture impermeable. The protective pouch is heat sealed all around except at a small area where the folded central extension tab of the liquid pouch passes through. The other two lateral extensions tabs at the opposite end of the liquid pouch are firmly attached by heat seal into the edge of the protective pouch. When manual traction is applied to the central slip tab it will cause the liquid pouch to rip and the fluid contained in the liquid pouch to be released and come in contact with the splint material.
10005] The dry splint as described in this invention is suitable for use with any orthopedic casting material that is water-curable. The liquid pouch may contain water or viscous water-laden gel, commonly used in cosmetic or medical industiy. The gel may also contain hardeners or accelerators that will interact with water curable resin such as tertiary amines, methylketones, copper or tin salts used in appropriate percentages.
|0006] The dry' splint system ofthe present invention provides a self-cured orthopedic splint material, which may consist of one or more layers of fiberglass or polyester sheets that are juxtaposed on top of each other. A liquid pouch containing water
-laden gel and a protective pouch which is air and water tight. The liquid pouch is supplied with an extension tab at one end, which can be pulled through causing the rupture of the pouch and the release of the water-laden gel to interact with the resin contained in the splint material. In order to facilitate the curing process, the operator will have to spread and knead the splint in order to spread the released fluid. The resin will then cure causing the dry splint to become hard. The outer bag of this splint system is a package that is formed of aluminum foil or plastic such as Mylar or alike. The outer pouch is resilient and tear resistant. It becomes obvious that the self-cured splint of the present invention avoids the prior art inconvenience and shortcoming of removing the orthopedic bandage and dipping it in water before applying it onto the patient.
[0007| Among other significant advantages of the dry splint of this invention, is that the protective pouch is sprayed with an antiseptic solution allowing the splint to be applied over an open wound or broken skin as frequently encountered in military battlefield, outdoors and vehicular accidents.
BRIEF DESCRIPTION OF THE DRAWINGS [0008] A greater appreciation for the embodiment of the present invention will be gained by consideration of the figures in which:
[0009] FIG. 1 is a perspective view of an embodiment of the invention showing the folded central portion to one end of the liquid pouch and the two side extensions to the opposite end of the liquid pouch.
[0010] FIG. 2 is a perspective view of the outer bag opened at one end revealing its content.
]ooiij FIG. 3 is a perspective view of the protective pouch opened at one corner exposing its content.
Ί [0012] FIG. 4 is a perspective view of the outer pouch with see through of the content including the protective sleeve, splint material and the liquid pouch comprising the folded pull through extension tab.
DETAILED PRESCRIPTION OF THE INVENTION [0013] Turning now to the drawings, in which similar reference characters denote similar elements throughout the several views, the attached figures illustrate a liquid containing pouch 1 sealed at its periphery 3 and having two short extensions tabs 4 and 5 at one end and a long extension tab 2 folded and laid on top of the pouch and pointing toward the opposite end of the pouch. The end of said long extension tab has a hole 11 to allow the operator a better hold and grab the end as seen in FIG. 1. The liquid pouch as described above is located on top or sandwiched between the layers of the cast slabs 9 situated inside the protective pouch 8 as shown in FIG. 2. Furthermore, protective pouch 8 is sealed all around 6 except for a small area allowing for the long extension tab 2 to pass through. Finally, the protective pouch and its contents will be packaged in a tear resistant, impermeable to water and airtight outer package 14.
[01).1.4] In use, the operator will manually tear the outer package and will remove the protective pouch 14 containing the casting material 9 and the liquid pouch 1. At this point, there is no need for using water or other liquid since the water for hardening the cast material will be supplied by the gel inside the liquid pouch 1. As seen in FIG. 1, tearing of the liquid pouch can be easily accomplished by holding the protective pouch at one end and firmly grasping extension tab 2 at the other end of the protective pouch and pulling it out. In doing so, the liquid pouch will be torn along its middle section throughout its entire length. Subsequently, the gel will escape and come in contact with the splint material 9. Kneading the protective pouch will facilitate spreading of the water laden gel over the entire splint material. The splint material 9 is conventionally made from fiberglass or weaved polyester impregnated with water curable resin such as polyurethane obtained from arylalkane diisocuanates and mainly from diphenyl methane diisocyanates, which will cure after been in contact with the water-laden gel and become hard allowing its use to immobilize a broken limb. It is clear that the advantage of having the water-laden gel in an impermeable pouch within a sterile protective sleeve is significant since it provides a simple self-curing, clean and fast method eliminating the need for messy wet conventional technique where the cast is dipped in non-sterile water. The dry and self-curing splint of the present invention will avoid application of wet splint directly onto the patient’s skin, which will cause maceration and infection.
[0015] The liquid pouch 1 as shown in FIG. 2, has two extensions tabs 4 and 5, which are secured and included in the heat weld 10 at the periphery of the protective pouch 8 so when the liquid pouch opening means 2 is pulled, the pouch will remain relatively stationary. In addition, the pouch will also be adherent to the splint material in view of the normally tacky nature of the water curable resin.
[0016] The gel used to cure the resin in the present invention can be usually supplied in rich in water gel like phase. Materials such as Propylene Glycol, Polypropylene Glycol, hydroxypropyl and hydroxymethyl cellulose as well as starch and thickeners. The amount of water needed to cure the resin and trigger the polymerization reaction is minimal. Furthermore, appropriate amounts of accelerators can be added to the water laden gel in order to facilitate and accelerate the resin curing process.
|0017] While the embodiment of the present invention as disclosed herein are considered for purpose of disclosure to be preferred, it is to be understood that this invention is intended to cover all changes and modifications in the disclosed embodiments which will fall within the scope of the invention.
