MEANS FOR APPLYING oAs'rs Lawrence Romaine Young, Seattle, Wash. Application December 12, 1945, serial No. 634,529

5 Claims.

This invention relates to a cast for application and to means for applying such a cast. Casts, as usually applied to parts of the human body are of one piece construction molded from plaster of Paris or like material. These casts are wet when applied, must dry out on the body of the patient, are heavyand cumbersome to wear and can not be taken off to permit inspection and treatment of a portion of a patient except by cutting them off and thus destroying the cast. Also these one piece casts are liable to have pressure spots therein which are painful to the patient and which can not be relieved without destroying the cast.

It is an object of this invention to construct a cast of two or more sections or pieces so that, after this cast has been applied to an injured portion of a patient, a part of the cast may be removed while the injured portion of the patient is adequately and safely supported in another part of the cast. This makes it possible to inspect and treat an injured portion of a patient and to make mechanical changes in a cast without destroying the cast.

Another object of this invention is to provide a simple and eflicient means for quickly, easily and inexpensively molding or constructing a multiple piece cast on an injured portion of a patient.

Another object is to provide a multiple part cast that may be quickly and easily applied to a portion of the human body and to provide a cast that is lighter and stronger than the usual plaster cast and one that does not have to be cut ofi of the body.

Another object is to provide a multiple part cast that can be molded on a portion of the body in such a manner as to reduce to a minimum the danger of internal pressure spots in the cast and to further provide a 'cast from which any internalpressure spots that are left in molding can be removedv or relieved by mechanical processes at any time after the cast has been completed.

Another object is to provide a. cast that can be quickly and easily opened up toprovide access to an injured portion of the body for the purpose of inspection, taking of X-ray pictureSQappIicathe application of the first half of the cast thereby making it easier to maintain the correct positioning andalignment ofthe injured body portion than it would be if a cast were being wrapped or molded entirely around the injured portion in one operation. I

Another object is to provide a multiple part cast in which internal padding can be renewed and lining material placed in the cast when desired, thus making it possible to internally pad the cast or to apply lining material to compensate for a reduction in size of an injured body member to whichthe cast is applied such as may occur when the swelling of an injured body member decreases. Y

Another object is to' provide a cast formed of parts which can be removed from the patient as soon as they have hardened or set for the purpose of completing the drying out of said parts, thus relieving the patient of wearing the cast while it is drying, shortening the timerequired for drying out the cast, and facilitating the taking oiX-ray pictures which are dificult to take through a wet cast. Another object is to provide a cast which can be removed and have holes drilled therein to lighten the weight of the cast and to provide for air circulation or ventilation andfor' the evaporation of body moisture.

Other objects of the invention will be ap arent from the following description taken in connection with the accompanying drawings.

In the drawings, Figure l is a plan view of, a

piece of castfor'ming material suitably shaped section of a flexible or conformable mold member constructed in accordance with this invention. Fig. 6is an elevation of said mold member looking in the direction indicated by the arrows of broken line 6--6 of Fig. 5. Fig. 7 is a sectional view takenon broken lines 1.-| of Figs. 5 and 6. Fig. 8 is an elevation of a spring clip or fastener used in connection with this invention. Fig. 9 is a detached view showing a fragment of a flexible strap member that is used for binding together two or more parts of my cast. Fig. 10 is a'detached view or a clip used in securing to- 3 gather two overlapped portions of a strap of the type shown in Fig. 9. Fig. 11 is a View in cross section illustrating the manner of using my cast forming apparatus in applying the lower half of a cast to a part of the body. Fig. 12 is a view in cross section showing the lower and upper halves of a finished cast secured together by a strap member of the form shown in Fig. 9. Fig. 13 is a view in cross section of a cast made in accordancetwith myiinvention aridiin 'whfch' the adjoining-dgesof the twucast members are overlapped.

that they will not interfere with each other when bent around the sides of the foot.

In applying a cast in accordance with this invention a rubber sheet 33 is laid on a table 46 or like support. Any desired number of metal straps 40 are laid across the rubber sheet 33. A piece of cast forming material such as the piece shown in Figs. 1 and 2 is placed on the rubber sheet 33 and is suitably moistened or otherwise treated to render it plastic and capable of' hardening or setting and to condition it so that it will readily conform to the shape of a part of the human body such as the back portion of a leg. The part of a patient to which the cast is to be applied, such as the leg, is positioned on the cast forming material. This may be done by moving the log onto the cast forming material or by moving the cast forming material under the leg. The sides of the rubber sheet '33 are then lifted up and two of the conformable side members 3l-32 are positioned alongside and pressed against the rubber sheet and the base flanges of the brackets 32 are pushed under the rubber sheet and under the cast forming material and body part supported thereon.

' The rubber sheet is drawn tightly over the top edges of the conformable members and is secured at frequent intervals, by clips of the form shown in Fig. 8, to the conformable side members 3I32. This rubber sheet 33, being elastic, yieldingly supports the moist cast forming material in such a manner that the cast forming material is caused to conform accurately to the shape of the part of the body to which'the cast is being applied. The body part is thus supported in the plastic cast forming material with the cast forming material preferably extending approximately half way around the body part so that when the cast forming material hardens it will provide half of a cast for the body part. If a cast is being applied to a leg and the piece of cast forming material shown in Figs. 1 and 2 is being used, then the rubber sheet 33 will extend under the foot piece 22 of the cast forming material and when this rubber sheet is drawn up the foot piece 22 of the cast forming material will first be raised and pressed against the sole of the foot, after which the footplate, Figs. 15 and 16, will be applied by slipping the flange 44 under the heel, pressing the upright portion 43 against the sole of the foot and bending the conformable tabs 45 around the sides of the foot so that the foot portion 22 of the cast forming material is supported over the bottom half of the foot.

When the cast forming material is drawn around .the sides of the leg and foot and before this material has started to harden or set, the edges of said cast forming material are shaped in any desired manner to provide for satisfactory edge to edge contact with the upper half of the cast. For instance, these edges may be flattened, as shown in Figs. 11 and 12, to provide a simple butt joint or they may be beveled, as shown in Fig. 13, to provide a bevel joint that will resist relative sidewise displacement of the lower and upper parts of the cast.

Afterward, the edge portions of the lower half of the cast are covered with strip material such as Cellophane and this covering material will prevent the adjoining edges of the upper half of the cast from adhering to the edges of the lower half of said cast. The upper half of the cast is preferably formed manually by applying cast forming material to the upper half of the leg -or other body part and properly molding and shaping the same. After the upper half of the cast has been properly applied then the straps 40 are drawn upwardly and around both halves of the cast, their ends are overlapped and the clips 42 are used to fasten these overlapping ends together. In applying these straps 40 the clips 42 are preferably inserted in the underlying strap end with their relatively fiat heads downwardly and their two prongs extending upwardly. The other strap end is then drawn snugly over the upper cast forming material and over the said underlying end and one of the openings 4| thereof is fitted over the prongs of a clip 42 and the prongs bent outwardly. When the straps are thus applied while the upper half of the cast is soft the soft cast forming material will tend to enter or bulge into'the openings 4!. When this cast forming material sets it will help to anchor the straps 40 more securely to the cast and thus tend to relieve the clips 42 of sheering strain. The heads of the clips 42, being thin and flat, will not have any appreciable tendency to form pressure spots in the cast.

If it is desired to permanently secure the ends or edges of two cast members together then preferably a wire connector member 48, Fig. 4, is embedded half in one cast member and half in the other cast member. Thus a wire connector member 43 may be partially embedded in one cast member and this cast member allowed to cure and set and later another cast member may be molded so as to embed therein the protruding part of the connector member 48 of the first cast member, thus permanently connecting the two cast members together.

If it is desired to mold an internal depression in any part of a cast this may be done by placing a pad M, Fig. 14, of soft material, such as cotton, on the part of the body to which the cast is to be applied before said cast is molded. As this cast is made in two or more separable pieces it is possible to cast an internal depression in a cast over'thelocation of an incision or injury to avoid painfi lllpressure on the injured spot.

' For purpose of illustration I have shown and described a cast that is made in two parts and I have referred to these parts as a lower half and an upper half. It will be understood however that this cast may be made in more than two pieces. Also it will be understood that said cast may be applied to a portion of the human body such as a leg or an arm or a trunk or torso so that the two parts of the cast are two side halves rather than an upper and lower half. Also it will be understood that pieces of cast forming material of all desired shapes and sizes to fit all parts of the human body may be provided or may be formed or prepared as needed, or that the cast forming material may be mixed as a plaster and thus used.

For instance in applying a cast to the leg of a patient the patient can be positioned on his back, on his face, on either side or in any intermediate position and the two parts of the cast can be applied to the bottom and top of the leg in whatever position the leg is placed. Thus the two parts of the cast can fit together at any desired location around the leg. A cast can be applied in a similar manner to an arm or to the body. In removing a part of the cast from an injured portion of the body it is preferable to let the injured portion of the body lie in the lower half of the cast and remove the upper half of the cast. This can be done by unclinching the clinched T. ends of.the:clips:=42:,joending the released end porr tions-.;oi.,the straps :40 outwardly and lifting;.oflf theatop segment of the. cast.: Thus the cast can beopened-up for inspection and treatment of the injured part without danger of damage, to the body part in-the cast. In this manner it is. pos-,

sible toopen up the cast first on one side and thenon the other without, depriving the injured portion of the body. of the support of the cast. The separable parts of the cast can always be replacedin their correctrelative positionsgontheinjured member. and. thestraps 40. again made fast-by the insertionand clinching of clip meme: bers 42.

Thiscast can be made from plaster; of Parisor from any other suitable material that can be made plastic and that will quicklyharden or set. It can be made in two or more seotionsasidesired and the cast can be of any. length and size, This cast can be molded so that the parts of thecast are .separable in any desired plane around the injured part to which the cast is'applied. It can be applied directly over the skin of a patient and then removed and linedlor internally padded if desired. It is less difi'icult and cleaner to apply than an ordinary cast and is not so liable to be fitted too tight for comfort. It is free from:the grit and plaster dust that results from the cutting oifsof an ordinary plaster of Paris cast.

Obviously changes in this castand the method or and means for applying the same may be made within the scope of the following claims.
