Abstract
ORTHOPEDIC SUPPORT PACKAGE AND METHOD A package for containing an orthopedic support constructed of open cell foam material may comprise a bag constructed of heat sealable thermoplastic multilayered film which is sealed along a single open edge after insertion of the orthopedic support therethrough into the bag. The orthopedic support is differentially compressed to such an extent as to reduce an irregular height dimension by a major amount with evacuation of a corresponding amount of air from the hag through the open edge prior to application of the heat seal along the open edge. An evacuated marginal portion of the bag extends outwardly about the orthopedic support by an amount corresponding to the reduction in height of the orthopedic support and results from the partial vacuum in the bag and the tendency of the open cell foam to rebound. The differential compression is obtained by using a press in compressing relationship with a press bed, applying compression to an extent which may be predetermined by utilizing a suitable stop means for limiting relative movement of the press members toward each other.

ORTHOP~DIC SUPPORT PACKAGE AND METHOD
Background of the Invention Storage is a major problem in connection with supplyiny foam orthopedic supports for patients of hospitals and other healthcare facilities due to the hul~y nature of such supports~ It is difficult to carry the foam supports, for example, upon the already crowded carts which are utilized by nurses and other attendants to supply patients with medication and other needs. It has even been found that patients who would be best treated with foam orthopedic supports are denied their use becaùse of the difficulties in supplying them to thP patients.
The most oommonly used method of packaging the foam orthopedic s~pports which have been in use here-tofore is through the use o heat shrinkable thermoplastic material. While such material affords an attractive sanitary package, there is little or no reduction in bulk.
~The prior art relating to the packaging of foam cushion~
includes United States Letters Patent No. 3,246D443, but this patent contemplates the use of individual sheets be~ween which the xegular shaped oam cushion is sandwiched.
The regular shape~ oam cushion with the thermoplastic sheets above and below on either side is compressed between press members acting a~ a bed ana a platen. The difficulty is that a seal is required on all sides of the package, and -~ while a uniformly aligned smoothly sealed package is ~ 9~6 ~ illustrated in the patent, it has been found that fxom a practical standpoi~t in commer~ial packaging involving sub-stantial numbers, such a package is difficult to achieve~
Further efforts include those exemplified by ~nited States Letters Patent No. 3,968,620 wherein an air suction apparatus is used to evacuate the air from a package contai~ing regularly shaped compressible material. This suction system is perhaps the most apparent solution to the problem, but the degree of compression or reduction in size of the foam article is not sufficient to achieve the desired results when supplying orthopedic foam supports.
Accordingly, the prese~t invention seeks to supply an orthopedic support package wherein the foam orthopedic support may be reduced in volume to such an extent as to make its storage and presence for use by a patient readily available.
Also the present invention seeks to provide a sanitary means of packaging an orthopedic support which will provide a longer storage shelf lie together with convenience in dispensing for supplying in health-care ~acil;ties to orthopedic patients.
Still further tlle in~ention seeks to provide a method of forming a package for reduc;ng the size of the orthopedic supports which may be relatively inexpensive and practical from the standpoint of providing reduced storage and space requirements to facilitate the supply;ng of orthopedic supports of the foam type to orthopedic patients.

Summary of the Invention It has been found that satisfactory orthopedic packages of reduced size may be obtained by utilizing a multi-layered thermoplastic bag which is sealed except for a single opening to accommodate reception of the orthopedic support within the bag. The orthopedic support is placed within the bag which is then pressed within a suitable compression applying means such as a press having members acting as a platen and as a bed. After compression has been applied so as to differentially compress the height dimensions of the irregularly shaped orthopedic support, and evacuating air from the bag, the sealing along the single open edge may be accomplished conveniently, and the marginal portions in that area trimmed away as by cutting. When the compressive action of the press is removed, an evacuated flat marginal portion of the bag extends outwardly entirely about the orthopedic support by an amount resulting from the reduction in height of the support due to the vacuum in the sealed bag and the tendency of the foam article to expand.
The invention in one aspect pertains to the met~od of packaging an orthopedic support comprising providing an orthopedic support constructed essentially of resilient synthetic open cell foam material with air entrained therein having a substantial and irregular height profile and a highly bulky configuration and providing a thermoplastic bag constructed of heat sealable thermoplastic film having a sufficient shelf life to prevent leaking and seeping of air affording storage of the package in a healthcare facility for extended periods of time, the bag having presealed edges but ~20!9~i~6 providing an open edge portion thereof for insertion of the orthopedic support therethrough, compressing the orthopedic support minimizing the bag size required, placing the orthopedic support thus compresed within the bag, differentially compressing the orthopedic support within the bag to such an extent as to reduce the substantial profile and bulk configuration by a major amount to a generally uniform flat configuration with e~acuation of a corresponding amount of air from the bag by urging a platen of a press into compressing relation with a bed of the press by a predetermined amount, placing a heat seal along the open edge portion after the compression and evacuation, and releasing the compressing action of the press after heat sealing the edge portionO
It is desirable but not necessary, that some mechanical means be employed for precompressing the foam article so that relatively small bags may be utilized thus conserving on the thermoplastic bag material and pexmitting a less costly process. This precompression may be obtained, for example, by forcing the foam article between constricting members which hold the bag on the outside thereof to facilitate reception through the open end of the bag of the precompressed orthopedic support.

member 14 having compressible portions 15 which may be constructed as from foam.
The press includes an upper fram~, broadly designa~ed at 16 which supports a fluid operated cylinder 17 which~ thxough the rod 18 operates the platen E. Suitable mechanical stop means are employed for limiting the down-ward movement of ~he press platen member, but t~ese stops are convèntional and are not shown except insofar as they may include portions of the seali~g means which come together and ~hich are d~scribe~ belo~.
A second hydraulic Qr air operate~ oylinder 19 has a piston rod 20 for owering a front gripping member 21 which bears against a first portion 22 ~f a U-~haped member which defines an opening 23 therein. The U-shaped member 22 at its back leg carries a wire or other suita~le heating element 24 which e~gages a back member 25 opposite the ~ember 21 for effecting a heat seal~C. The heat sealing operation occurs immediately following compression ~y the lowering of the platen E by actuation of the cylinder 17 by lowering of the memb~rs 21 and ~5 by operatio~ of the cylinaer 19 which follows evaauationO Together with ~9~
the sealing operation A, a transversely movable knife 26 is provided for trimming of an edge 27 of the bag, primarily for eslthe~ic reasorls, but also to provide a uniform pacXage edge. Xnives of the type illustrated at 26 are common expedients in various sealing operationsO
By reference to Figure 2, it will be noted that, after the sealing operation forming the seal C, the k~ife 26 moves transversely in the direction of the arrow to trim off the edge 27. It will be fuxther noted that auring and prior to compression, the edges of the bag are expanded or substantially V-shaped, but by xeference to Figur~ 3, it will be noted that after re val of the com-pression by raising the platen E, that the edge portions of the bag are sucked together because of the vacuum obtained within the package and because of ~xpansion of the foam member A after remov~l of ~he compres~ionO The edges B thus form~d are significant in that ~hey may be-punctured by an attendant which permits full expa~sion . o~ ~he orthopedic suppoxt within ~he bag prior to tearing awa~ the bag for u~e. Thu~, a limited sanitary storage in.expanaed condition is possible and if ~his is not desired, the bag may be easily removed at once without damage to the orthopedic supportO
It has been ound that it is possible to reduce the height dimension of the open cell type polyurethane foam materials which ar~ often usea in orthopedic supports by an amount ~n excess of about 80%~ or to approximately a 6 to 1 reduction of the unxestricted he~ght of the ~2~9S4~;
.,. . ;
orthopedic 'support~ Such foa~ material has a densi~y on the order of about l.Ç3 pound~ per cubic foot, and an indentation load defle~tion of about 34 to 38. It is important that the material of the thermpolastic bag be capable of being heat sealed and that it h~ve sufficient shelf life to prevent leaking and seepaye of air or affording a suitable shelf life.
Such material has been found to be of a multi~layered thermoplastic film material such as designated as B-620 bag supplied by Cryovac. This multi-layer sealing bag is designed ~pecifically for vacuum packaging of fresh meat, bu~ it has been found ~hat this bag may serve the purpose of containing the orthopedic support as des~ribed herei~. It is not believed at present that the heat shrin~able material often employed in wrapping meat would be suitable for the purposes d~scussed hexein.

~t will be observed that the presealed e~ges as illustrated at 30 are somewhat irregular after packagi~g ana sealing, while ~he seal C is fairly regular in its alig~ment. The article contai~ed wi~hin the marginal portions which extend thereabout ana which contain collapsible portions of the bag ~erYe to retain the orthopedic support in compressed relation. The height aimension ~s reduced while the general outline remains fairly unifoxm except that the thic~-: ened portions of thè article extend outwardly as illustrated at 31. ~he vert;cal opening is somewhat elongated as illustrated at 32.
