Aqueous Propulsion Devices For Prostheses

BACKGROUND

Human mobility is a necessary component of everyday life that is often taken for granted. Walking, running, swimming, and similar activities are needed for transportation, exercise, or recreation. In instances where an individual's limbs are afflicted with severe pain, disease, or injury, the ability to move around can be significantly hindered, if not altogether halted. In such circumstances, the affected limb(s) may be surgically removed and replaced with a prosthetic limb. While prostheses greatly improve the ability of a person to move around comfortably, they do not always restore full mobility in all scenarios.

One challenge faced by those who utilize lower-limb prostheses is moving effectively in water. In fact, many currently available lower-limb prostheses are not even waterproof, and those that are fail to enable a user to swim through the water with a satisfactory amount of propulsion due to the rigidity and relatively small lateral profile of the prosthesis. This, unfortunately, forces individuals to forgo an enjoyable and highly-effective form of recreational enjoyment and exercise, thereby contributing to a decreased overall quality of life.

SUMMARY OF THE DISCLOSURE

In some aspects, this configuration may enable a user to exert one or more pushing forces on an amount of water or similar fluid via the protruding extension members 1205, 1206, 1207, 1208 when the user engages in a kicking or similar motion, thereby propelling the user through the water in an intended direction.

In some non-limiting exemplary embodiments, each protruding extension member 1205, 1206, 1207, 1208 may be at least temporarily secured to at least one portion of the lower-limb prosthesis 1225, 1226, 1227, 1228 via one or more attachment mechanisms 1265, 1266, 1267, 1268.

Referring now to FIGS. 13A-13B, front views of an exemplary aqueous propulsion device 1300, according to some embodiments of the present disclosure, are illustrated. In some non-limiting illustrative embodiments, the aqueous propulsion device 1300 may be integrated with a lower-limb prosthesis 1325. In some implementations, the bottom portion of the lower-limb prosthesis 1325 may comprise an artificial “foot” portion that may be dislodged or released from a first position that may facilitate ambulatory movement of a user, and rotated or pivoted to a second position via rotation about at least one hinge, wherein a plane comprising the “foot” portion may be substantially parallel to the longitudinal axis of the lower-limb prosthesis when in the second position. In some aspects, the “foot” portion may be locked or snapped in to the second position using at least one securing mechanism to prevent or minimize unintentional movement of the “foot” portion, such as, for example and not limitation, by using one or more detents or similar catches.

In some implementations, once the “foot” portion of the lower-limb prosthesis 1325 is in the second position, one or more protruding extension members 1305 may be altered from a retracted position within one or more internal portions of the “foot,” such as, for example and not limitation, slots, chambers, or similar receptacles, to an extended position, wherein the protruding extension member(s) 1305 may be fully exposed when in the extended position, such that they may be used to exert a pushing force on an amount of water or similar fluid when a user engages in a kicking or similar movement, thereby propelling the user in an intended direction and facilitating the ability of the user to swim or otherwise move through the fluid, as non-limiting examples. In some embodiments, each protruding extension member 1305 may comprise a substantially flat or substantially planar structural configuration, such as a “fin” or “wing” design, as non-limiting examples. In some implementations, the protruding extension member(s) 1305 may be configured to be locked into place when in the extended or retracted position, such as, for example and not limitation, via one or more detents or similar catches, wherein at least one release mechanism may be configured to be actuated by the user to unlock and release the protruding extension member(s) as needed.

In some aspects, by configuring the “foot” portion of the lower-limb-prosthesis to convert from an ambulatory position to an aqueous propulsion device 1300, a user may be able to experience maximum utility of two different use configurations using a single apparatus. In some implementations, this may enhance user convenience and efficiency, as non-limiting examples.
