IMPROVEMENT IN TRUSSES.
The Schedule referred to in these Letters Patent and making part of the same.
l .Tous Goeman, of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improved Truss and Truss-Pad for Hernia, dre., ol which the following is a specification.
Nature and Object of thc Invention..
My invention consists of a truss provided with a lever and a projecting nut, which turns on an cecentricpin, so that a lateral adjustment of the nut may be obtained by merely turning the saine.
My invention fnrthur consists of the combination of the said lever, its nut, and adjustable shield, as fully described hereafter.
Description of the Accompanying Drawing.
Figure 1 is an edge view of my improved truss. Figure 2, a iront view of the sani General Description.
lhe truss consists of what l have termed an abdominal lever, A, and of a shield, B, and projection or uut C, secured to one. end of lthe said lever. i'
The abdominal lever consists of upper and lower plates d and dl, suitablyl curved and connected together by a bent or curved neck di.
'lhe upper plate is adapted to the shape of the lower part of the abdomen, and is intended to fit comfortably agaii'ist the same with a slight degree oi' pressure.
This plate, for the sake of lightness, and for the admission of air, may be perforated with a number of holes, e, as shown.
The lower plate lll of the lever, which l have termed the orifice-plate, is intended to cover the groin or inguinal region, the seat of the hernia or rupture.
This plate is nearly dat, and has secured to its inner face the eccentrically-adjustable nut C and shield or guard B, before referred to.
At the back of the plate lthere should be a projectii'ig screw or button, for the attachment of a spring and strap, to secure the lever to the wearers body.
.lhe projection or orilice-nnt G is intended to enter the oi'iiicc or lower ring of the inguinal canal, in oi'- der to press back the hernia, and may resemble, in shape, the end of the thumb, or be made round, oval, or other suitable form.
It is secured to the plate (il of the lever by a screw, j, in such a inannei that it can be adjusted eccentrirally upon the same, or it may be secured by means of an eccentric stein at its inner end, adapted to a socket formed in the plate.
The guard or shield VB is also secured to the plate ft' by one or more screws, in such a manner that it may be readily adjusted thereon, and is made of the peculiai' curved or scmicireular shape, best observed in fig. 2, in order that it may partially surround the orice-nut, and, by bearing against the parts ofthe body beneath the orifice, and on the side toward the hip, regulate the pressure ofthe said nut upon the hernia.
The raised portion of the shield immediat-ely sur rounding the orifice-nut consists of a ridge somewhat liigher than the nut at x, and tapering inward from this latter point toward the plate dl, the said ridge being so reduced in height at its upper end :is to meet the plate, while, at its lower cnd, it terminates abruptly in a point, ai', a short distance outward from the plate. (See iig. 1.
The inner edge ,i/ of the shield, which surrounds the orifice-nutis nearly vertical, and the portion y ofthe said shield is beveled, or gradually rounded off to a thin edge, so as to fit comfort-ably against the parts with which it is brought iii contact.
The above-described truss, when adapted to the body ofthe wearer, is held in a'proper position by the spring and strap before referred to, the springr passing half way round the body, and pressing both the orifice-nut and the shield equally upon the hernia.
As the abdominal lever A, which forms the body of the truss, is adjustable upon the spring, and as the critico-uut and shield are both adjustable upon the lever, it will bc evident that all of these parts can be set at any desired angle, and in any position, to suit the patient, and nature ofthe rupture.
The lever A acts as such, iii case of sneezing, coughing, 8:0., the plate (l being, in such case, forced outward with the protrusion ofthe abdomen, and
forcing the plate lll, whicl1.forins the short arin of the lever, inward, in opposition to the elort of the hernia to protrude by such act of sneezing or coughing, the lever turning upon the spring, to which it is attached, as a fulcruni.
The-lever A should be made of'such a shape as not to press severely upon the abdomen in the act of steopin fr.
It should also be made flatter upon its inner than on its outer edge, as shown in fig. 2, so that when two of thctrusses, or a truss and a pad, are used, one upon each side, they may not strike together, or otherwise interfere with cach other.
' It will be observed that the oricennt and shield Claims.
1. The pressure-pad or 1everA, provided with a supplemental pad or projection, turning on a. pin arranged eccentric to the point of the projection, as described. e
2.-The combination, substantially as herein described, with the lever and its adjustable nutl C, of' a shield, B, adjustable laterally on said lever, in the manner described.`
In testimony whereof, I have signed my nume to thsspecification in the presence of two subscribing witnesses.
