A hypertension brace of cruciform shape having four pads, including sternal, pubic and two side pads, in which each of the four arms is longitudinally adjustable so as to facilitate fitting the patient. Further, at least the sternum pad is flexibly mounted to enable easy comformability to the sternum area of the individual patient.

with the vertical arms attached to the outward side of the horizontal arms as seen in FIGS. 1, 3, 4 and 9 and centrally secured together by rivets, as at 20. The structure is shaped so as to be concave toward the body (FIGS. 1, 2, 4 and 8). The upper arm has a longitudinal slot 22, the lower arm a longitudinal slot 24, and the arms 16 and 18 have pluralities of threaded bores 26 and 28, respectively. As will be seen below, these comprise parts of the means for adjustably mounting movable arms on the fixed arms 12, 14, 16 and 18. to provide a maximum range of sizes from a single device. The latter arms are considered fixed because they are rigid with each other because of the riveted attachment at 20.
In the known prior art, especially in the Freeman device, arms equivalent to the arms 12, 14, 16 and 18, carry pads for body contact. In the present invention, four pads are used, comprising a sternum pad 30, a pubic pad 32 and right and left side pads 34 and 36. In contradistinction to the prior art, the present invention utilizes supplementary adjustable arms for mounting the pads on the basic structure 10. Thus, the sternum pad 30 is mounted on a movable arm part 38 (FIG. 8), and the pubic pad 32 is mounted on a movable lower arm part 40 (FIG. 1). The upper or sternum arm part 38 is slidably carried by the fixed or basic upper arm part 12 by means of the slot 22 and a set (here a pair) of securing means in the form of screws 42 threaded into two of three threaded bores (one visible at 44 in FIG. 3) in the movable arm part 38. The movable lower arm part 40 carries the pubic pad 32 and is similarly carried on the lower fixed arm part 14 via the slot 24 and a pair of screws 46 threaded into two of three threaded bores 48, one of which is seen in FIG. 3. The movable upper arm part 38 and lower arm part 40 are positioned on the inner side of the fixed arms 12, 14 as seen in FIGS. 1, 3 and 8.
The normal ranges of adjustability, the two outer bores 44 (or 48) are used to receive the screws 42 (or 46) to achieve stability, but when a greater range of adjustability is required, the outermost screw may be used in the next adjacent bore, thus increasing the range by, say 1.3 3.8 cm (11/2 in.). Therefore, one device can be of a universal size capable of being adjusted to all standard adult sizes.
It will be seen from FIG. 8 that the free end of the movable arm part 38 is slightly offset at 50 inwardly as respects the posterior of the patient, thus improving the sternum-to-sternum pad contact, supplemented by a flexible attachment element 52 secured to the front side of the sternum pad 30, and the rear side of the arm part 38. The sternum pad 30, like the other pads, is preferably constructed of plastic, having a rigid layer 54 56 and a foamed or resilient 56 54. The plastic used may be of any acceptable type, such as polyethylene or polypropylene, bonded together in any suitable manner. The attachment element 52 is likewise plastic, bonded to the pad 30 and arm part 38 and is of such nature as to provide a "living" hinge, i.e., it is permanent even through it is capable of flexing about a plurality of axes so as to partake of bending, twisting, etc. thus enabling the sternum pad to readily conform to variations in sternum shapes and forms. A flexible element 58, like the element 52, similarly connects the pubic pad 32 to the lower movable arm part 40.
It is to be noted that the sternum pad has a shape quite different from pads of the prior art, being of generally arcuate shape as seen from the front, having an upper concave edge 60, a lower convex edge 62 and rounded side edges 64 joining or fairing into the aforesaid edges. These edges are designed to give the wearer greater freedom of movement in the neck area while still applying the necessary contact forces to surrounding parts of the body. It should also be noted that the pubic pad 32 has a shape identical to that of the sternum pad 30 seen in FIGS. 1 and 3 allowing a single die to punch the two pads thereby lowering manufacturing costs.
The side pads 34 and 36 are mounted respectively on moveable arm parts 66 and 68 (FIGS. 3 and 4) via the threaded bores 26 and 28 and slots 70 and 72 respectively in the arms, together with sets (here pairs) of screws 74 and 76. The movable arm parts 66 and 68 are positioned on the outer side of the fixed arms 16, 18 as seen in FIGS. 1, 3, 4 and 9. Thus, the assembly of fixed arms 12, 14, 16 and 18 and movable arms 38, 40, 66 and 68 as seen in FIGS. 3 and 4 is never more than two arms thick. What has been said about the slot and screw means 22, 42 and 44 and 24, 46 and 48 above, applies here as to slidable adjustability and range of adjustment. The side pads 34 and 36 are formed in a curved manner as shown in FIG. 6 and are to be positioned at the front of the patient's side as FIGS. 3, 4 and 6 illustrate and not directly at the side as is universally done in the prior art. This frontside positioning permits the slidable adjustability required for universal sizing which is not available in prior art devices.
Typical of a hyperextension brace is the use of a back pad and means connecting same to the front structure to apply forces to the back or lumbar area. In the present case a back pad 78 is used, here to the same dual-layer construction as those previously described. The back pad has slots 80 and 82 in wing or rear portions at opposite sides thereof (FIG. 5) and these are used in conjunction with means for securing the back pad to the side pads 34 and 36. The preferred securing means comprises right and left pliant elements in the form of straps 84 and 86 (FIGS. 1, 2, 6 and 7). Since these are identical (although symmetrical) in the present case, only the strap 86 needs description in detail. As best seen in FIG. 6, the pad 36 has an outwardly protruding stud or the like 88 to which the inner end 90 of the strap is attached, the strap having a suitable aperture 92 therein. The strap, so attached to the stud 88, which may be headed to prevent accidental dislodgment of the strap, is reeved thru the associated slot 82 in the back pad and returned to the stud 88, to which it may be attached by any one of a plurality of apertures 94 spaced equally apart lengthwise of the strap. A preferred spacing is about 3 cm (11/2 in.). Each strap is provided with a finger loop 96 at its free end to facilitate manipulation, the purpose of the adjutability being to secure the proper application of forces between the posterior structure 10 and the back pad 78, depending upon the dimensions, condition etc of the patient.
