Description

FIELD

The present invention relates to devices used as splints. More particularly, the invention relates to a modular multi-positional rigid splinting device for use in both pre-clinical and clinical settings.

BACKGROUND

The need for an easily transported, rigid, reusable and mechanically simplistic splinting system exists both inside and outside of the medical community, especially in physical activities where the risk of extremity injury is present such as in hiking or other sports. Preferred embodiments of the invention allow for stabilization of an extremity injury, especially in a pre- clinical or emergency setting, to occur expeditiously with minimal assembly, resulting in a savings of time and effort for the user and/or patient. The invention can also be adjusted to accommodate the swelling of the extremity and/or affected joint. The shape and construction of the splint halves provide both consistent rigidity and stability not easily obtained by existing systems.

Certain existing splinting and stability systems have been previously developed for treatment of pre-clinical/field extremity injuries. These systems, though quickly deployable and easily transported, suffer drawbacks such as a lack of permanent rigidity necessary to maintain the stabilization of an injured extremity under compression conditions such as that of an impact or applied weight. These existing systems are prone to deformation with repeated use which could increase the likelihood of further patient injury.

BRIEF SUMMARY OF THE INVENTION

The present invention describes a multi-positional, modular bodily limb splinting system consisting of at least one pair of rigid, shared geometry interlocking segments which allow for expedient placement and treatment of a limb injury.

In one embodiment the invention includes a male splint member with a locking post and an adjustable locking post at one end and a female splint member a locking aperture operable to receive and interlock with the locking post and a plurality of adjustable apertures operable to receive and interlock with the adjustable locking post. The interlocking mechanism of the embodiment allows the alignment of the male splint member and the female splint member to be angularly adjusted in a multitude of positions as indicated by the patient's injury. The configured splint is held to the extremity by fastening means, including the use of binding straps. The interlocking male and female splint members are configured to be stacked upon themselves and secured for storage and/or transport using the elements' shared geometrical design features. The singular components require no additional construction beyond the joining of the splint members and the strapping of them to the extremity.

The configured splint may be applied to any extremity in any position or direction, including (but not limited to) anterior, posterior, lateral, and medial positions of an extremity for the purposes of stabilization. The system provides static components for precise positioning of the injured joint or extremity, which in turn allows adjustment and repositioning to be executed quickly.

Turning to FIG. 1, the splint 10 having a male splint member 20 and a female splint member 30 is shown in a stacked configuration with the male splint member 20 positioned beneath the female splint member 30.

As shown more clearly in FIG. 8, the male splint member 20 includes a first end 40 and an opposing second end 50. The first end 40 can come in a variety of shapes and sizes, but at a minimum, must include a locking post 80, preferably positioned in the radial center of the first end 40 and an adjustable locking post 90 offset from the locking post 80. The female member 30 has a first end 60 opposite a second end 70. Like its male counterpart, the first end 60 can come in a variety of shapes and sizes, but the preferred embodiment includes a locking aperture 100 positioned, preferably positioned at its radial center that is operable to receive the locking post 80 of the male splint member 20, and a plurality of adjustable locking apertures 110 disposed circumferentially along the perimeter of the first end 60, each operable to receive the adjustable locking post 90.

The male splint member 20 and female splint member 30 are locked in a fixed position when first end 60 of the female splint member 30 is placed over the first end 40 of the male splint member 20 such that the locking post 80 is slotted through the locking aperture 100 and the adjustable locking post 90 is slotted through one of the plurality of adjustable locking apertures 110 (as shown in FIGS. 1-4 and 9-11). This means for interlocking the male splint member 20 and female splint member 30 allow the splint 10 to be assembled ambidextrously in any direction or angle from 0 to 360° . In FIG. 9, the dashed lines more clearly depict potential positioning for the interlocked male and female splint members 20, 30 at incremental angles within a 360° range.

In preferred embodiments, the male splint member 20 and female splint member 30 may be made from a variety of thermoplastic or metallic materials, including but not limited to, Acrylonitrile butadiene styrene and polylactic acid thermoplastics, in addition to aluminum or similar metals, or suitable materials which may produce a suitably durable and rigid surface.

Turning back to FIG. 1, the male splint member 20 and female splint member 30 interlock such that the members 20, 30 are stacked upon each other, which allow for increased rigidity if being used for splinting a bodily limb, or alternatively, allow for easier transport and storage of the splint 10 when not in use. The second end 50 of the male splint member 20 and the second 70 of the female splint member may also include a mounting aperture 71 operable to receive a mounting accessory (e.g. a carabiner) that, when stacked as shown in FIG. 1, allow for the members 20,30 to be mounted to another accessory (e.g. belt) using the mounting accessory.

In another embodiment, the exterior surface of the male splint member 20 and female splint member 30 may be lined with a slip resistant material to assist in securing the members 20, 30 together when in a stacked relationship, or to a bodily limb when being used as a splint (as shown in FIGS. 10 and 11).

As shown in FIG. 2, a top-view of the splint 10 is shown with the male splint member 20 and female splint member 30 joined in a 180° configuration. In preferred embodiments, the user can secure such a configuration, on one or more sides of an injury, to provide joint immobility using strapping or other means. FIGS. 3-7 depict alternative views of the same configuration.

Turning to FIG. 10, a perspective view of the splint 10 is shown being used with an arm. In this embodiment, the splint 10 includes two male splint members 20 and two female splint members 30 positioned laterally and medially to the arm with the interlocking male and female splint members 20, 30 connected adjacent to the elbow joint. Binding straps 130 slotted through the strap receiving slots 120 on the splint members 20, 30 are used to secure the splint members 20, 30 to the bodily limb.

FIG. 11 illustrates a perspective view of the splint 10 as applied to a leg according to various embodiments of the present invention. Two sets of male and female splint members 20, 30 are positioned laterally and medially to the leg with the first end 40 of the male splint member 20 interlocking the first end 60 of the female splint member 30 adjacent to the knee joint. The splint members are secured to the leg by binding straps 130 secured around the leg and through the strap receiving slots 120 disposed along a length of the male and female splint members 20,30. In the preferred embodiment, the strap receiving slots 120 disposed on each pair of male splint member 20 and each pair of female splint members 30 are in alignment when the members 20, 30 are interlocked and positioned around a bodily limb, as depicted in FIGS. 10 and 11, and secured by fastening means, including but not limited to, hook and loop fasteners (e.g. VELCRO), snap buttons, clasps, or buckles.

In the preferred embodiment, the binding strap 130 is removable from the male and female splint members 20, 30, which allows for easy replacement when the strap becomes worn. However, alternative embodiments may include a more durable strap that is fixed, attached, or woven into the male or female splint members 20, 30.
