REPLACEABLE RIGID CAST WITH INTEGRAL FASTENERS
TECHNICAL FI5L
This invention relates todevices useful for immobilizing parts of the body. More particularly, the present invention relates to a rigid cast which may be removed and subsequently replaced, useful for immobilizing or compressing parts of the body, and which conforms tσ the shape of said body parts, and which also overcomes obstacles present with the use of rigid casts which, subsequent to removal, are not replaceable.
BACKGROUND ART Rigid casts and the like of the type used to prevent the mobility of, or to apply desired compression to, injured or otherwise damaged parts of the body, or combinations of these, have been known and used for centuries. Such rigid devices have been applied to the injured body part in recent times in a series of steps which permit wrapping of the injured limb or other body part with a flexible bandage or the like, followed by the application of a medium, suchasplaster ofparis, fiberglass, etc., whichsubsequently hardensonthesurfacetoproducearigidproductwhicheffectively prevents mobility and may also apply a degree of compression to the injured part.
Rigid casts of the prior art describe a plurality of improvements thereto, however, such casts thus described, when removed for any purpose, are not reuseable on the injured limb, and must be replaced if removed by repeating the application process professionally at considerable time and expense and varying degrees of risk in attaining the original shape of the prior cast and in duplicating the degree of compression of said cast. While supports for injured limbs are described in the prior art, such as traction bands and the like, and while these are removable and replaceable at will, such devices
are not rigid and do not generally supply the required support for the proper healing of broken or more severely damaged parts of the body. U.S. Patent No. 3,867,930 to Brown describes a necessarily flexible and removable traction band of this type with such limited use, which is fabricated from a multi-ply fabric supplying the required tension. U.S. Patent No. 1,980,486 to King efe al. describes a device secured to the patient's foot with straps, however, the teachings set forth therein offer no substantial means of support tσ a broken or more severely damaged limb. U.S. Patent No. 2,875,752 to Lovich describes an improvement relating to a foot support for a rigid, though not removeable and replaceable, cast, having similar functiontothatofSilvermaninU.S. PatentNo. 3,584,402. Of the prior art references available, none are found to overcome the burdens of removing and easily replacing a rigid cast which has been molded specifically to conform to the contour of an injured body part. PISCEQSUfig QF THE INVEflTIQE Inthebroadestaspects, thepresentinventionisdirected to a rigid cast useful for immobilizing an injured part, whichis removableandsubsequentlyreplaceableafterremoval, and having rigid body part immobilizing parts adapted to at leastpartially surround an injured bodypart. Preferably, at least one material may be shaped to conform to the contour of said body part, said material being affixed with cooperating fasteners for securing said rigid parts, thereby allowing the resultant components to achieve immobilization of said body part. Inapreferredembodiment, thepresentinventionisdirected to a rigid cast useful for immobilizing an injured bodypart, whichis removableandsubsequentlyreplaceableafterremoval, comprising: a rigid structure of at least two rigid body part immobilizing outer parts adapted to at least partially surround an injured body part; at least one soft inner material, which is shaped to conform to the contour of said body part; and a plurality of cooperating fasteners
securing said rigid parts thereby allowing the resultant components to achieve said immobilization of said body part; said rigid cast being applied to said body part by: (1) applying a casting medium to said body part which has been suitably prepared to accept same, thereby forming a unitary rigid supporting shell; (2) cutting and removing said rigid shell, thereby forming two or more complementary parts; (3) attaching said plurality cooperating fasteners to said complementary parts; and (4) replacing said cast on said injured limb with subsequent fastening of said cooperative fasteners to form a rigid structure.
In a more preferred embodiment, the present invention is directed to a rigid cast which is useful for immobilizing an injured body part comprising: a first rigid shell which is shaped to conform at least partly to said body part; a second rigid shell which is adapted to conform at least partly to said body part and which is adapted for a tight connection with said first rigid shell along at least one longitudinal edge thereof; and a plurality of adjustable fasteners for fastening said first rigid shell to said second rigid shell along said longitudinal edge, each of said adjustable fasteners comprising a first base portion having a plurality of projections secured to one of said shells, a second base portion secured to the other of said shells, said second base portion having attached thereto a tightening lever and a connecting loop adapted for connection with any one of said plurality of projections whereby the pressure of said rigid shells against said body part can be adjusted.
