Ischial perineal cushion for emergency traction splint
| Details |
Inventors: Borschneck, Anthony G.;
Assignee:
Primary Examiner: Hafer; Robert A.
Assistant Examiner: Owens; K.
Attorney, Agent or Firm: Lothrop & West
In order to distribute the countertraction forces exerted on the perineal region by a cushion mounted on a lower limb emergency traction splint, the cushion is formed to an elongated saddle shape with enlarged lobes on opposite ends. The cushion is made laterally bendable so that when applied to the patient, the cushion impinges against the ischial tuberosity, the ischial and pubic rami and the midline symphysis pubic. Patient comfort and splint security are thereby enhanced. |

DETAILED DESCRIPTION While the perineal cushion of the invention is susceptible of several different variations, depending upon the environment and requirements to use, it has been successfully embodied in the form disclosed in the following description and accompanying views of the drawing.
The cushion of the invention, generally designated by the reference numeral 8, has been developed as an improvement over the substantially linear countertraction cushions heretofore used on emergency fraction splints of the general kind disclosed, for example, in Joseph A.
Sager U.
S.
Pat.

4, 1973.
The present cushion is characterized by its compliance to being selectively bent to assume a desired one of a variety of shapes in order to distribute, in optimum fashion, the countertraction force exerted by the splint as traction is applied in order to maintain alignment of a fractured leg bone.
In overall aspect, the cushion 8 includes an elongated, end-lobed body 9 having an internal core portion 10 covered with padding and an unpadded projecting core portion 11 serving to connect the cushion to the splint and to hold a thigh strap.
The internal portion 10 and the external portion 11 are together, termed a core 12, or plate, or base, and is constructed of a plastic material, such as polyethylene or of metal.
In the form of device illustrated in the Figures, compliance, or bendability, of the cushion 8 is attained by hinging together two sections of the core 12.
Hinging is afforded by a hinge 13 including a hinge pin 14 fitting very tightly in the circumscribing walls of the hinge sockets 15 formed on the respective sections.
In side profile, as appears most clearly in FIG.
2, the core 12 includes a concave upper edge 16 and a concave lower edge 17.
The core 12 extends between opposite ends 18 and 19 and includes opposite side faces 21.
The core 12 comprises a long section 22 and short section 23, the abutting portions of the sections 22 and 23 being joined along the hinge 13
