.QMM ,flgmbwww ATTORNEYS Some of the objects of the invention having been stated other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which:

FIG. 1 is a front elevational view of the thoracic belt of the present invention as it is worn about a patients thorax;

FIG. 2 is a rear elevation of the thoracic belt as it is worn about the patients thorax;

FIG. 3 is an enlarged perspective view looking at the inside or body-engaging surface of the thoracic belt;

FIG. 4 is a perspective view looking at the outside surface of the thoracic belt; and

FIG. 5 is a fragmentary sectional view taken substantially along line 5-5 in FIG. 3 and illustrating the resilient spongelike material bonded to the inelastic fabric of the end panels to present a soft, yieldable friction surface on the inner face thereof.

' I-I ere tofore, it has been quite common to effect such controlled tension or expansion through the use of inelastic tape which is highly uncomfortable in that it permits virtually no expansion, or through the use of various types of elastic beltlike splints, which, although more comfortable, do not properly control expansion. Additionally, such beltlike splints normally present problems in remaining in place during use,

-and accordingly, it has been proposed to add shoulder straps or suspenders to the same to keep the splint from sliding down the patient s body.

It is an object of this invention to provide a thoracic splint or belt which is so constructed from a combination of elastic and inelastic panels that the inelastic panels are adapted to give maximum support to the ribs and rib muscles of a patient while the elastic panel is adapted to fit in the spinal area of the thorax, thereby permitting expansion only at that point where the ribs are connected to the spine, which is the least likely zone of injury.

A more specific object of this invention is to provide a thoracic belt having elongate opposite end panels intercon- I nected by an intermediate elastic panel of trapezoidal configuration, and wherein the end panels are each provided with a body-engaging facing of resilient spongelike material bonded thereto and presenting a soft, yieldable friction surface which prevents slippage of the belt when it is firmly bound about the patients thorax.

Another object is to provide a thoracic belt of the character described which includes fastening means, preferably of the Velcro type, for readily detachably securing opposed ends of the belt together in overlapping relationship without re- 1 sortingto the use of straps and buckles, for example.

' against stretch in use. The end panels 1 1, 12 are provided with respective body-engaging or inner facings l3, 14 (FIGS. 3 and 5) of resilient spongelike material to present a soft, yieldable friction surface to the patients body and which prevents slippage of the belt when it is firmly bound about the patient's thorax as shown in FIGS. 1 and 2. It is preferred that the

bodyengaging facings

13, 14 cover substantially the entire inner surfaces of the respective inelastic panels ll, 12 and that the facings are formed of closed cell polyurethane foam adhesively or otherwise suitably bonded to the inner surfaces of the inelastic panels ll, 12.

The proximal end edges of the inelastic panels ll, 12 are spaced apart from each other, but are attached to the nonparallel opposite end edges of an elastic intermediate panel 15 of substantially isosceles trapezoidal configuration. End panels 11, 12 are each of about the same width as the length of the nonparallel end edges of elastic intermediate panel 15 and are preferably of about the same width throughout their respective lengths so that the opposite side edges of each end panel extend substantially perpendicular to the respective nonparallel end edges of the intermediate elastic panel 15 when the thoracic belt 10 is not in use, as shown in FIGS. 3 and 4.

Elastic panel 15 is made from suitable elastic woven webbing with the elastic strands thereof extending parallel to the parallel opposite side edges of the trapezoidal elastic panel 15, so that the elastic panel 15 is of substantial stretchability in a direction generally longitudinally of belt 10, but is substantially nonstretchable transversely of the belt 10.

When worn, the thoracic belt should be placed tightly about the patients thorax. Therefore, in order that the junctures of the three panels l1, l2, 15 do not form objectionable ridges which would make uncomfortable indentations in the patient's body, it is preferred that the proximal end edges of the end panels ll, 12 abut, rather than overlap, the respective nonparallel end edges of the elastic intermediate panel 15, as shown in FIG. 5. The abutting edges at the junctures of the end panels with the intermediate panel are secured together by lines of zigzag stitching indicated at 110, 12a in FIGS. 3 and 4.

Suitable fastening means are provided for fastening the distal end portions of end panels ll, 12 in overlapping relationship to snugly secure the belt about the patient s thorax, as shown in FIGS. 1 and 2. It is preferred that a so-called Velcro" type of fastening means is employed in which a plurality of laterally spaced short strips of textile pile material 20 is secured to the outer or distal end portion of one of the end panels, and wherein a plurality of hook strips 21 is suitably attached to the outer or distal end portion of the other end panel.

As preferred, the strips of pile material 20 are secured, by suitable stitching, to the inside surface of end panel 11 (or to the facing 13 thereof) adjacent that end of the first end panel 11 remote from elastic intermediate panel 15. Hook strips 21 are also secured, as by suitable stitching, to the outside surface of the second end panel 12 adjacent the end thereof remote from elastic intermediate panel 15. Hook strips 21 may be of a type such as is disclosed in U.S. Pat. No. 2,717,437, issued Sept. 13, 1955, wherein the hook strip is provided with tiny fiber hook elements extending outwardly from one side of a backing material and which will become embedded in and will cling to a soft fibrous material when pressed thereagainst. Usually the material against which such hook strips are pressed to form a fastening means is a napped textile material. Since the fastening means described herein and embodied in the pile strips 20 and hook strips 21 is fully disclosed in said U.S. Pat. No. 2,717,437, a further description thereof is deemed unnecessary. In fact, it is to be understood that other fastening means, such as snap fasteners, may be employed without departing from the invention.

When the thoracic belt is placed about the thorax of a patient, as shown in FIGS. 1 and 2, the longer of the two parallel side edges of the elastic intermediate panel 15 faces upwardly and is located about the middle of the back of the patient. While the second end panel 12 is held against the chest of the patient, the first end panel 1 l is pulled tightly into overlapping relationship with respect to the second panel 12, whereupon the strips of pile material 20 are pressed into surface contact with the hook strips 21 to snugly and firmly secure the thoracic belt about the thorax of the patient.

Owing to the fact that the end panels ll, 12 converge downwardly at a relatively slight angle with respect to the upper, longer, side edge of the trapezoidal elastic intermediate panel 15, the thoracic belt 10 has a natural somewhat tapered configuration when it is placed about the thorax of the patient so as to conform more readily to the shape of that portion of the patients body. Also, since the upper portion of the elastic intermediate panel 15 is of greater length than the lower portion thereof, it can be appreciated that its upper portion is more easily stretched than the lower portion thereof. Consequently, the upper portion of the thoracic belt 10 readily yields to the expansion of the patients chest incident to his breathing, while the lower portion of the belt still maintains snug supporting engagement of the thoracic belt with the patients body.

The facings l3, l4 engaging the body of the patient not only cushion the belt with respect to the patients body so that the patient is quite comfortable while breathing, but the facings l3, 14 also present a nonslip friction surface against the body of the patient so that the thoracic belt will not normally be displaced when it is being worn even though the patient may inhale and exhale very deeply, thus obviating the need for any additional supporting means or straps for maintaining the thoracic belt in the desired position at all times while it is being worn.

lt is important to note that the construction of the belt 10 is such as to provide firm support about the entire critical zone of the patients thorax with the only longitudinal expansion and contraction of the belt, attendant to the patients breathing, occuring along a relatively short length of the belt at the spinal area of the thorax; i.e., at the elastic panel 15. As is generally known, most rib injuries generally occur forwardly of the spinal area. Thus, by restricting all expansion and contraction of the belt to the spinal area, the patient may breathe as comfortably as the injury will permit without the pain of such injury being aggravated by the thoracic belt as has been the case with prior art types of thoracic belts whose portions forwardly of the spinal area would move relative to the patient's body during expansion and contraction of the thorax.

In the drawings and specification there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
