Definitions

  • showering does not require a second thought. But for many people who have leg amputations, it is a risky and dangerous task, even when implementing the most elaborate safety precautions.
  • Showering is normally a difficult task for people with amputations, and normally they must either sit on a chair, sit on the ground, or stand on one foot. These options are not convenient or comfortable and, in the slippery conditions of a shower, standing is especially dangerous. Falls do happen and can lead to severe injury, including landing on and causing further damage to the residual limb, or injuring their only working leg. Additionally, every amputation is different, and the user’s unique needs can be overlooked. No two amputations result in the same residual limb, so each case is expected to vary.
  • the device for providing support to a standing human.
  • the device includes a plate including an upper portion and a lower portion, wherein the upper portion of the plate is adapted and configured for providing support to a human leg.
  • the device also includes a handle that is attached to a proximate edge of the upper portion of the plate, such that the handle extends approximately perpendicularly upwards from the upper portion of the plate.
  • the device also includes a foot that is attached to the lower portion of the plate through a pylon, such that the foot is approximately parallel to the upper portion of the plate.
  • Ranges provided herein are understood to be shorthand for all of the values within the range.
  • a range of 1 to 50 is understood to include any number, combination of numbers, or sub-range from the group consisting 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 (as well as fractions thereof unless the context clearly dictates otherwise).

  • the present disclosure provides a design and construction of a lower limb prosthetic device suitable for shower use.
  • This device is specifically applicable for people who have undergone transtibial (below the knee) amputations, although alternative embodiments can be suitable for transfemoral amputations.
  • Certain embodiments of the prosthetic device can be waterproof and suitable for standing in the shower. Certain embodiments of the prosthetic device can be adjustable, portable, and cost affordable.
  • Certain aspects of the prosthetic device include portability, ease of use, and adjustability. Certain embodiments of the device can be easily compactable so that it can be stored away while also having the ability to be easily transported.
  • the device can be easy to use practically and can be configured to allow for drainage of water during the shower.
  • the device can be configured to be easily cleaned, assembled, and disassembled.
  • the device can contain multiple points of adjustability, so that it is more practical for a wide range of people.
  • the device can include a plastic foot with non-slip rubberized materials located on the bottom of the foot. Such features provide traction and reduces the likelihood of any slippage when in use.
  • the non-slip foot can include a large surface area to increase friction and contact with the ground or floor (e.g., slippery tile floors).
  • the structure, including the nonslip foot can be configured to mimic the natural functionality of a real foot. This allows for a more natural human gait cycle when walking, while also enabling an effortless transition from the sitting to standing position. Such configurations can enable easy transitions from sitting to standing and walking.
  • the device can also feature a height-adjustable handle proximally adjacent to the user’s hip, thereby allowing the user to hold the device and apply downward force and pressure through the device, similar in some ways to a cane or crutch.
  • the adjustable handle provides extra stability and can include a strong rubberized grip.
  • the height adjustable handle working in unison with the rubberized grips, allows for more security and stability when navigating with the device.
  • the curvature of the shin plate allows users to rest a portion of their lower limb on the device as it can support the load of their entire body weight.
  • the device can also replace the need for a lower limb through all phases of the normal gait cycle.
  • the device can support the full body weight of the user by allowing the user to rest their shin on the plate (e.g., the primary shin plate).
  • the device can include a pylon made from PVC pipe which is perforated and secured to the plate (e.g., the shin plate) and foot.
  • the pylon can include pins (e.g., corrosion resistant stainless steel pins), making the device height adjustable and uniquely compactable. Such features can allow users to disassemble or reassemble the product quickly (e.g., in under 1 minute), and fit the entire device into a small bag.
  • the device (including the plate, handle, foot, and pylon) can be made from a multitude of materials, such as waterproof materials and suitable biocompatible materials.
  • the device can include an adjustable strap that secures a shin portion of a person’s limb to the device.
  • the strap can be configured to easily attach to the device.
  • the strap can be configured to secure the person’s leg to the device quickly (e.g., in less than 5 seconds).
  • the plate e.g., shin plate
  • the plate can be covered with a soft, comfortable, water compatible padding (e.g., made from neoprene or another suitable material) that reduces fatigue resistance.
  • the padding can be curved to fit the average shin shape of a human.
  • the padding and curvature of the plate allows the device to comfortably support the average lower limb physique.
