INVENTOR CURT JOHNSON ATTORNEYS ARMSLING This invention relates to an improvedsurgical arm sling and particularly relates to an improved arm sling which is easy to apply, readily adjustable, comfortable, washable and therefore readily sterilized, and which effectively holds the patients arm in the proper position. i 1 Various types of surgical arm slings'have been proposed and constructed over the years. Probably the most familiar type of arm sling, commonlyreferred to as anenvelope sling, comprises a triangular-folded cloth or bandage which is secured behind the neck of the patient by joining the free ends thereof as by a knot and-whichdepen ds to support the patients arm. The pressure of the knot on the patients neck, the inability of the sling to be readily adjusted, the factthat the knot often contoured seat inwhich the patientsarm. rests. One knowntype sling provides a pair of such'arcuate'metalpieces connected together to form a combination contoured over the shoulder'and .arrn support. "These. metal. parts, however, are
most uncomfortable, particularly where paddinglis not also It is a feature hereof that the patient may don the sling himself without other assistance. This is accomplished by forming the sling to a substantially figure-eight configuration whereby the upper loop portion maybe readily'slipped about the patients neck by use of his other arm thereby automatically positioning the lower loop portion-of thesling in front of the patient ready to receive his arm. The lower loop portion can then be positioned about the patients injured arm by his other arm. An adjustable buckleis provided in the upper loop portion to facilitate application of the upper loop portion directly over the patients head. The upper loop portion can thus be selectively adjusted in length as to be applicable directly over the-head regardless of head size or hands. Additionally a buckle is provided in the lower loop portion whereby the length thereof can be readily adjusted even when the sling is in position supporting the patients arm. In this manner,. the
proper arm position can be readilyv achieved by selective manipulation of the strap through the buckle. Note that the threaded reception of the lower strapportions through the fabric straps pennits adjustment of the lower padding along the lower strap portion whereby the. lower padding can be located in proper position to receive the arm regardless of the employed'Moreoven.slings employing such arcuate metal 'partslack' the comfort and. adjustability offa fully flexible arm sling, for example,.on'e*comprisedsolely of .a fabric material.
Another type-of arrn- Sling comprises a canvas straphaving' loops at both ends through .whichz'the wrist and forearm portions of the patient's'arm are.re ceived, the strap extending about the nape of thepatienfis neck providing therequisite support. This type of str ap has' also proved somewhat uncomfortableand is easily moved out of thelproper position. i
In general, it hasbeen found .thatexisting arm slings suffer from one or more'disadvantages'. articularly certainof the conventional arm slings cannot be donnedv by the patient himself without assistance and this most often means that a doctor or nurse must be available. Certain .of the present day slings are' not readily adjustable andsometimes a-variety' of slings must be donned 'iri 'order to" obtain a sling which -willlfit properly. The presentgday slings are generallyuncomfortable as their strap, metal portions, buckles and the like tend to bear against the "patients body, thereby causing chafing and discomfort. Additionally, certain existing slings resulting from efforts to solve the foregoing discussed problems have proved somewhat complicated and expensive to manufacture.
The present inventionprovides an improved surgical sling which minimizes the above discussed and other shortcomings of prior arm slings and provides various advantages in con- --struction, mode-of use,-and result over such prior arm slings.
To accomplish this, the present invention provides an arm sling formed of fabric straps arranged-to comprise upper and f lower loop portions generally forming a figure eight. Forming a part of the upper loop portion is a padding of plastic foam material enclosed in a-fabricstockinet whereby the upper loop portion can be locatedabout the patients neck. A padding of fabric encased-foam material also forms a partof the lower loop portion.. The lower padding .also has a pair of spaced fabric strapsformed at its underside forthreadedly receiving the strap'portionof the lower-loop portion whereby the padding can be adjusted alongthe strap portion to provide a forming the sling of flexible fabric strap material, theportions of the sling which bear against the patients body are fully padded therebyoptimizing the weight distribution of the arm fortable cushioned fit.
accordance withthe principles of the adjusted length of the lowerloop portion.
Accordingly, it is a'primary object of the present invention 'to provide an improved surgical arm sling which is comfortable'to wear and which is provided with padding at the pressure It is still another object of the present invention to provide an improved surgical arm sling wherein the level-of the arm can be readily and easily adjusted.
improved surgical arm sling which is readily washable and It is a further-object of the present invention to provide an sterilized for reuse. I 7
It is a still further object of the pre'se'ntinvention to provide an improved surgical arm sling which can be readily and easily manufactured at low cost, whichis formed of conventionally available materials, and which can be used interchangeably as a collar and cuff sling and a long arm cast sling.
These and further objects and advantages of the present invention will become more apparent upon reference to the following specification, appended claims and drawings wherein:
FIG. 1 is a perspective view ofanarrn'sling constructed in present invention and shown applied to apatient; I
FIG. 2 is an enlarged perspective view of the arm sling hereof;
. FIG. 3 is an enlarged fragmentary perspective view of the intermediate portion of the sling and illustrating the adjusting buckle therefor; andv FIG. 4 is an enlarged cross sectional view of the intermediate portion ,of the sling.
Referring now to the drawings, particularly FIGS. 1 and 2, there is shown an arm sling, generally. indicated at It),
preferably comprised of a continuous fabric strap arranged 1 generally in the form of a figure eight and having upper and lower loop portions 12 and 14, respectively. Portions of the continuous strap forming the loop'portions l2 and 14 are the latter are adjustable in length. Since the buckles l7 and l8 are identical, the following description of the lower buckle is believed sufficient to describeboth buckles, the various parts of the upper and lower buckles being identified by the letter reference U and L respectively 'following'the corresponding numeral reference. Asseen in FIG. 3, the lower buckle 18 comprises a rectangular shackle 20 having side bars 22L which slidably mount a cinching member 24L; One end of shackle 20L comprises a locking bar 26L which has a serrated or roughened inner edge indicated at 28L. Buckle 18L includes a clasp 30L having a reversely bent lip or catch 32L which, together with the body portion of clasp 30L, defines an opening beneath lip 32L for receiving the end bar 34L of shackle 20L. The opening is preferably slightly smaller than the diameter of end bar 34L such that the latter must be s ipped past the opening whereby shackle 20L and clasp 30L calabe releasably fastened one to the other. The opposite end of clasp 30L is slotted as at 36!. to receive a looped portion of the continuous strap as will be described.
Referring now to FIG. 2, neck padding 40 comprises an elongated rectangular block of padding material 42 preferably a plastic foam material, encased within a fabric stockinet 44. The ends of the stockinet 44 are gathered about strap portion 12 at opposite ends of block 42 and a pair of fabric strips 46 are folded about the gathered ends of the stockinet and the strap portions thereat, the strips 46 being stitched along their edges to each other and to the stockinet and strap portions to encase the foam material 42. The upper loop strap portion 12 extends through neck padding 40 between the stockinet 44 and foam material 42 on the rear or outer side of the latter and it will be seen that neck padding 40 is thus fixed in position along upper loop portion 12 and at a position therealong substantially opposite intermediate fastening strap 16,
An arm or wrist padding, generally indicated at 48, is provided lower loop portion 14 and comprises an elongated block of padding material, preferably a plastic foam material, encased within a fabric stockinet 49. A pair of spaced fabric straps are sewn at opposite ends to the stockinet 49 forming a pair of spaced loops on the underside of padding 48 to receive the lower strap portion 14. The ends of stockinet 49 are tucked in about the ends of the padding 48. The lower strap portion 14 engages about the underside of padding 48 and threads though the loops 50. Note that, with this type of securement between arm or wrist padding 48 and lower strap portion 14, padding 48 can be selectively located along lower strap portion 14 as desired.
To arrange the single continuous strap comprising the upper and lower loop portions in a manner as to form arm sling 10, the strap (FIG. 2) is inserted through shackle 20L from its underside, reversely folded about cinching bar 24L and threaded between cinching bar 24L and rear bar 26L to terminate in a free end 19. The strap extends from the lower buckle 18 along the underside of wrist padding 48 and through the loops 50 as previously described and extends to central portion 16. The strap then passes through the slot 36L (FIG. 4) of lower buckle l8 and extends a short distance whereupon it is reversely folded as at 52 to extend for a like distance in the reverse direction and is again reversely folded as at to extend through the slot 36U of upper clasp 30U. There is thus formed three layers A, B and C of strap at central portion 16 which are stitched together one to the other as at 56, the outer layers A and C forming a pair of loops to retain the respective clasps 30U and 30L at central portion 16. The strap extends from central portion 16 and passes through neck padding 40 as previously described. The opposite end portion of the strap engages through the upper shackle U from the underside and is reversely folded about cinching bar 24U and threaded between cinching bar 24U and rear bar 26U to terminate in a free end 60.
In use. upper loop portion 12 is adjusted in length as to be comfortably received over a patient's head and is then disposed about the patients neck such that neck padding 40 is located about the nape of the patients neck with the lower loop portion 14 depending in front of the patient. The length of the neck padding 48 is sufficient to accommodate lengthwise adjustment of the upper loop portion 12 and still engage about the nape of the patients neck when worn. The lower end of the strap can then be threaded through shackle 20L of buckle 18, if not already threaded tlierethrough. The length ofthe lower loop portion can then be adjusted such that the lower portion thereof is located at the proper height for maintaining the patients arm in a level position. If the adjustment in length of the lower strap portion 14, in order to provide support for the arm at the proper position, locates arm padding 48 at a position other than directly below and underlying the patients arm, it will be seen that arm padding 48 can be readily displaced along lower strap portion 14 to thus locate it in proper position underlying the patients arm. Note further that when the padding 48 is properly located, the patients arm or wrist rests or bears against the central portion of the padding which, in turn, bears against the underlying supporting strap whereby the arm is cushioned by the padding.
When the sling is finally adjusted and in proper position as seen in FIG. 1, it will be appreciated that paddings 40 and 48 provide cushioning at the pressure points thereby affording a comfortable fit. It is a further feature hereof that by providing a half twist to the upper strap portion between the fastener strap 16 and one end of neck padding 40, the upper strap portion [2 lies substantially flat against the patient's chest whereby the bearing pressure is again distributed over the widest possible area.
Furthermore, by providing an arm sling formed substantially of a combination fabric and plastic foam material, it will be seen that the sling is readily washable and hence effectively sterilized. Thus, the arm sling hereof can be employed many times over. Moreover, the sling can be economically manufactured as the fabric, foam and stockinet materials are readily commercially available at minimum cost.
Thus, the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing descriptions and all changes which come within the meaning and range of equivalency of the claims are therefore to be embraced therein.
