DESCRIPTION OF PREFERRED EMBODIMENT
An arm sling, generally designated 20, includes a tubular arm support 22 and a neck strap 24, for detachably receiving a patient's arm, generally illustrated in chain lines at 26. The tubular arm support 22 is fabricated from a single sheet 32 of pliable material, such as cotton cloth, which is cut along the pattern illustrated in FIG. 5 to provide two identical panels 40 and 41 which are then folded about a fold line 23 to the confronting positions illustrated in FIG. 7 or rolled into a tubular configuration as illustrated in FIGS. 1-4 with the free terminal edge portions, generally designated 34 and 36, disposed in confronting relation and sewn or otherwise coupled together along an upper stitch line 38 to provide an upper border 33 of a predetermined length 33A and a lower border, generally designate 35, of a substantially greater length. The lower border 35 includes a forward lower border portion 37 of a predetermined length 37A which is greater than the upper border length 33A and a rear lower border portion 39 having a predetermined shorter length 39A which is substantially less than the upper border length 33A.
The pliable material for the sheet 32 may suitably comprise cloth fabric which is porous and is of sufficient length to loosely receive the forearm 28 and allow the passage of ambient air thereto. The tubular arm support 22 includes first and second, elongate, substantially identical opposing sidewall panels, generally designated 40 and 41, having upper edges or borders 42 and 44, respectively, and lower edges or borders 43 and 45, respectively.
As illustrated in FIGS. 5 and 7, the lower borders 43 and 45 are integrally coupled together at fold line 23, however, it should be understood that individual panels 40 and 41 could be utilized and stitched or otherwise coupled together. The upper borders 43 and 45 are initially disposed in the same plane (FIG. 5). The lower edges or borders 43 and 45 of panels 40 and 41, respectively, include front lower edge or border portions 46A and 47A, respectively, each having a length 37A and rear lower edge or border portions 46B and 47B, respectively, each of a lesser length 39A. It should be noted that the lower rear edge portions 46B and 47B in the “laid out” planar positions illustrated in FIG. 5 initially diverge rearwardly and are thereafter coupled together to form the lower rear edge portion 39 which is upwardly rearwardly inclined relative to the front lower edge portion 35 to form an elbow receiving pocket 54.
It should be noted that the length 37A of the front lower edge or border portion 35 is substantially longer than the rear pocket forming lower edge or border portion 39. The front lower edge portions 46A and 47A form the front lower edge or border 35 and the rear lower edge or border portions 46B and 47B are stitched together at 53 to form the lower front lower rear edge portion 39 and are of the same length 39A.
The confronting side panels 40 and 41 include confronting front edges 60 and 61, respectively, and confronting rear edges 62 and 63, respectively which, when folded about junction 23 from the flattened or planar condition illustrated in FIG. 5 to the folded position in FIG. 7, or rolled to the rolled, operative tubular position illustrated in FIGS. 1-4, cooperate to form a front opening 64 of a predetermined breadth or diameter 65 and a rear opening 66 having a predetermined larger breadth or diameter 67 through which the user's arm is positioned in the tube 22. In the folded confronting positions of the panels 40 and 41 illustrated in FIGS. 1, 3 and 7. The junction 23 defines the lower front border 37.
The upper border 33 and lower front border 37 rearwardly diverge from the front plane 70 to the beginning point 58 of the upwardly inclined pocket forming border 39 which, as illustrated in FIG. 1, converges upwardly. It should also be noted that the entire upwardly inclined pocket forming rear lower border 39, commencing at 58, is disposed rearwardly of the upper border 33. The junction of the rear end of the upper border 33 and the upper ends of the rear edges 62 and 63 is identified by the reference numeral 89.
It should also be noted that the breadth 59 of the tubular passage portion located at line Z extending between the junction 89 and the opposite point 58 at the front end 58 of the rear pocket forming lower border portion 39 is larger than either of the breadths 65 or 67 of front and rear end openings 64 and 66, respectively.
It is further noted in FIG. 1 that the junction 87 of the rear end of pocket forming rear border portion 39 and the lower ends of the rear edges 62 and 63 is at a higher level than the junction 88 of the front end of the front lower border portion 37 and the lower ends of the front confronting edges 60 and 61.
A pair of longitudinally spaced fastener strips 69 and 71 are fixed to the upper border 34. It is noted that the longitudinal midpoint 74 of the rear strap 71 is positioned substantially along the junction 89 of the rear edges 62 and 63 and upper border 33.
As illustrated in FIG. 1, the front confronting edges 60 and 61, forming the front opening 64, lie in a plane 70 and the rear opening forming confronting edges 62 and 63 lie in a second plane 72 forming the rear opening 66, which upwardly converges toward the plane 70.
The neck strap 24 comprises an elongated carrier line 82 having terminal ends mounting a pair of male fasteners 84 which are detachably received by a pair of complementally formed female fastener receptacles 78 coupled to the pair of short fastener strips 69 and 71 that are sewed or otherwise attached to the upper border portions 34 and 36. A suitable pad or cushion 86 may be placed on the upper strap 82 to provide the user with additional comfort while wearing the sling.
The sling, constructed according to the present invention, includes no obstructing vertical back wall that must be negotiated in order to insert the arm into the tube.
The Operation and Method
A pliable sheet of fabric material 32 is cut to the shape illustrated in FIG. 5 providing substantially identically shaped panels 40 and 41 which are the mirror images of each other joined at a fold line 23. Initially, the pocket forming lower rear border portions 46B and 47B rearwardly diverge relative to each other and the front edges or borders 46A and 47A lie in the same plane. The panels 40 and 41 are folded toward each other about the fold line 23 so that the upper borders 34 and 36 are disposed in confronting relation and stitched together at 38 to provide the upper border 33 as illustrated in FIGS. 1-4. The confronting lower rear terminal ends 46B and 47B are also stitched or otherwise coupled together to form the elbow receiving pocket 54 along the rear lower end portion of the arm receiving tube. The cooperating fasteners 78 and 84 are coupled together and the neck strap 86 is disposed over the user's neck and support thereon.
The user's arm supported by the tube 22 can be disposed across the font of the user's chest and the straps 82 may be adjusted on fasteners 84 until the pocket 54 is disposed at a level not lower than the level of the patient's elbow 30. The patient need not be concerned about positioning the elbow 30 at the exact location but merely slips the arm through the opening end or opening 66 until the forearm 28 is disposed in the tubular section 22 and the elbow 30 is disposed in the elbow receiving pocket 54 as illustrated in FIG. 1. The substantially shorter length 33A of the upper border 33 relative to the length 37A of the lower border 37 and the relative larger diameter rear opening 66 allows the user to easily dispose the arm 28 within the tube passage.
It is to be understood that the drawings and descriptive matter are in all cases to be interpreted as merely illustrative of the principles of the invention, rather than as limiting the same in any way, since it is contemplated that various changes may be made in various elements to achieve like results without departing from the spirit of the invention or the scope of the appended claims.
