HERNIAL TRUSS.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed. December 30, 1904, Serial No. 238,954. Renewed June 5, 1909. Serial No. 500,401.

To all whom it may concern:

Be it known that 1, JOHN ALLAon BUNKER, a citizen of the United States, residing in the borough of Bronx, in the city of New Yorl; and State of New York, have invented new and useful Improvements in Hernial Trusses, of which the following is a specification.

This invention relates generally to certain improvements in trusses and particularly to the pads thereof and has for its main or ultimate object the provision of a pad having spring tension members and provision for adjusting the pressure exerted by the same, whereby the pad is adapted to be used for different ruptures, scrotal, umbilical or femoral for example.

The invention consists in certain peculiarities in the construction of parts and in certain novel combinations of elements substantially as hereinafter described and particularly pointed out in the subjoined claims.

In the accompanying drawings, I have illustrated an embodiment of the present invention which is preferred for the reason that by it the full measure of advantages is best secured, but changes in the detail embodiment shown may be made without departing from the spirit of the invention.

In said drawings :Figure 1 is an outer face view of the base plate of a pad embodying my improvements, showing the ends of the waist and crotch straps connected with the spring tension devices thereof. Fig. 2 is a rear face view of the pad, showing a portion of the same broken away to disclose the base plate and Fig. 3 is a detail view of one of the spring tension devices and its support. I

The same reference charactersdesignate the same parts in the several views.

A designates a pad which is preferably oval and is provided with any suitable means or inner-surface portion (as indicated at A, Fig. 2) for contact with the wearer. Upon the outer face of this pad there are mounted a plurality of spring tension devices B which are adjustable relatively to each other and are engaged by the waist. belt and crotch straps C and D, as indicated in Fig. 1. The spring tension devices preferably employed are of that type which hold the pad yieldably to the rupture and with a pressure which increases when the abdominal wall is expanded; each comprising a sprlng element, such as the 0011s 1 connected with each other by a loop 2 constituting an outward projecting means adapting the spring for connection with the waist belt or crotch strap, and each of said coils terminating at one end in an arm or projection 3 which presses the pad toward the wearer.

In operation the belt and strap are drawn sufliciently tight to put the springs under tension, which is communicated to the pad, and when the abdominal wall is expanded additional pressure is imposed on said belt and strap and the same are caused to pull the loops of the spring tension devices outward, thus giving the effect of an elongation of said belt and straps, which compensates for such expansion and avoids an uncomfortable increase of pressure of the belt and straps upon the person of the wearer, and at the same time increasing the tension of the coiled spring 1 and causing the same through the arms 3 to press the pad more firmly to the wound. Thus protrusion of the wound is efiiciently prevented when the wearer coughs or bends forward as well as at all other times, and the truss may be worn with a minimum of discomfort.

The series of spring tension devices are preferably arranged to provide, in addition to one for the crotch strap, a plurality or pair adapted to be arranged near one end of the pad or above the horizontal center thereof, and a second plurality or pair adapted to be arranged near the other end of said pad or below the horizontal center of the same, which devices are adapted to be engaged by the waist strap or belt C, which latter has at each end a plurality of independently adjustable straps C each of which is suitably engaged with the spring tension device contiguous to it. The inde pendent adjustment of said straps C may be provided for in various ways, such, for example, as the buckles C shown. The crotch strap D has one of its ends similarly, or by other suitable means, attached to its spring tension device and its other end is suitably secured to the belt or strap C. Thus, the straps may be adjusted to cause the pressure upon the wound to be, or to p'reponderate, in an upward or downward direction, or to be equal throughout the entire effective area of the pad. Thus, if the tendency to protrusion is in a downward direction, the lower straps C may be drawn more tightly than the upper ones, whereby the lower spring tension devices will be put under greater tension than the upper ones and the pad thus caused to impose pressure in an upward direction, while if a downward pressure is desired the upper straps are tightened more than the lower. ones, and if a direct upper pressure (in a horizontal line) is desired the four straps are tightened equally. Each of these spring tension devices is mounted upon a plate 4 which constr tutes a base therefor, and said plate is provided with a strap 5 through which extends a pin 6 which also extends through said coils l and serves to secure the parts together. lgach of said plates at is pivotally mounted. it is very acvantageous to mount the pivots adjustably on the pads, which is best accomplished by mounting them in an elongated slot 7 formed in the pad A. Preferably, the pivot is composed of a screw 8 engaged by a nut 9, as shown, whereby the parts may be fixed in adjusted position. Thus, the pad is provided with a plurality of groups of spring devices, which groups are adjustable relatively to each other and each member of each of which groups is adjustable relatively to the other member thereof. It will be observed that said adjustments are for the purpose of changing the relation of the spring devices to each other and to the pad in order to further adapt the pad for the treatment of different types of hernia. It is considered to be very advantageous to use a series of five of said spring tension devices arranged in two groups of two and three respectively and to mount the members of each group upon a common pivot S from which the members extend in different directions.

It will be observed that the construction described provides a very advantageous means for giving any desired direction of pressure and for adapting the pad to various ruptures. Thus, in the form shown in Fig. 1 the pressure is directly inward and approximately equal throughout the area of the pad, but this pressure may be changed in various ways, for example, by adjusting the straps C as above stated; or by adjusting the members of either or both groups of tension devices pivotally relatively to each j other: or by adjusting the groups bodily toward or from each other (which gives a pressure in an upwardly or a downwardly inclined direction, according to their location with respect to the center of the pad) or by removing one or more of the members of either group, or one or the other group as an entirety; or by certain combinations of such suggested adjustments. It will be understood that when the pivot screw 8 is slacked up or loosened either of the members secured thereby may be turned pivotally or the group moved bodily in the slot and that when said screw is tightened the members will be fixed in their adjusted position: and, further, it will be evident that when either of said pivot screws 8 is withdrawn, any of the tension devices thereon may be removed bodily, if its use is not needed. This last named adjustment is desirable when, for example, the pad is to be used for the treatment of umbilical hernia in which event the bottom tension device and leg strap are not needed.

In practice the under or rear face of the pad A will be covered by suitable means such as A, Fig. 2 which will render the de 'ice comfortable to the wearer, but the particular means for this purpose form no part of the present invention and many suitable for the purpose will readily suggest themselves to those persons skilled in this art.
