Anterior compartment muscles of the thigh include pectineus, sartorius, and the four muscles that comprise the quadriceps muscles-rectus femoris, vastus medialis, vastus intermedius and vastus lateralis.

Semi-powered lower extremity exoskeleton

The lower extremity exoskeleton comprises two leg supports connectable to person's lower limbs and configured to rest on the ground during their stance phase. Each leg support comprises a thigh link and a shank link; a knee joint configured to allow flexion and extension between the shank link and the thigh link. The lower extremity exoskeleton further comprises an exoskeleton trunk connectable to the person'supper body. The exoskeleton trunk is connectable to the thigh links of the leg supports allowing for the flexion and extension between the leg supports and the exoskeleton trunk. Two torque generators are coupled to each of the knee joints. A power unit, capable of providing power, is coupled to the torque generators. In operation when a leg support is in a stance phase and climbing a slope or stairs, the power unit injects power into the respective torque generator thereby extending the respective knee angle. When a leg support is in stance phase and not climbing a slope or stairs, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to resist flexion of the respective knee joint. When a leg support is in a swing phase, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to minimize its resistance to knee flexion and extension.

Walking assistance device

The present invention provides a walking assistance device comprising a pelvis support member (10) adapted to be worn on a hip of a wearer; a thigh support member (20) adapted to be worn on a thigh of the wearer; a leg support member (40) adapted to be worn on a leg of the wearer; a knee joint hinge (60) disposed at a position corresponding to a side part of a knee of the wearer and connecting the leg support member (40) to the thigh support member (20) in a manner that enables back-and forth rotation of the leg support member (40) with respect to the thigh support member (20); and a power generator assembly (100) mounted to the pelvis support member (10) at a position corresponding to a side part of a hip joint of the wearer; wherein the power generator assembly (100) comprises a hip joint power generator (110) and a knee joint power generator (120) each having an output member (116, 126, respectively), with the output member (116) of the hip joint power generator (110) being connected to the thigh support member (20) in a power-transmittable manner and the output member (126) of the knee joint power generator (120) being connected to the leg support member (40) via a power transmitting mechanism (90) which transmits power generated by the knee joint power generator (120) to the leg support member (40).

Above-knee prosthesis with variable resistance knee joint

InactiveUS20050015156A1Decrease resistance of flexion and extensionImprove the immunityArtificial legsFree rotationVALVE PORT
An above-knee prosthesis that allows the user to control the resistance of knee flexion or extension, and to voluntary lock and release the knee joint, at any and all bending angles, comprising a thigh frame assembly that receives a thigh stump; a leg frame assembly with foot attached; a hinge interconnecting the thigh frame and leg frame assemblies to form an artificial knee joint; a closed hydraulic system further interconnecting the thigh frame and leg frame assemblies to provide resistance to the bending of said artificial knee joint, a means to vary the resistance provided by said closed hydraulic system, and a means to translate the AP movement of said thigh stump into the degree of resistance provided by said closed hydraulic system. In its preferred embodiments, the AP movement of the thigh stump is communicated by means of a linkage, sliding or screw assembly, to a flow rate control valve. The flow rate control valve varies the amount of the resistance provided by the closed hydraulic system controlling, thereby, the amount of resistance within the artificial knee. Pressing the thigh stump backwards within the thigh frame assembly increases the resistance within the hydraulic system and slows knee bending until the knee locks. Pressing the thigh stump forward decreases the hydraulic resistive force and allows the artificial knee joint to yield to outside forces, such as gravity and / or stump thrust, until the prosthesis rotates freely about the knee hinge. The above-knee prosthetic prevents the knee joint from giving way, promotes a balanced stance, and facilitates a near normal reciprocating gate while ascending and descending stairs and slopes.

Fastening tab and side panel of disposable diaper and disposable diaper

There is provided a fastening tab or side panel for a disposable diaper (herein below sometimes referred to simply as a “fastening tab”) with an opening formed in the fastening tab or side panel base member or a notch on the terminal end of the fastening tab or side panel base member. When an invention fastening tab or side panel of an adult or baby disposable diaper (herein below sometimes referred to simply as a “diaper”) is pulled outward, the fastening tab or side panel in some embodiments can be pulled out by hooking the fastening tab or side panel at an opening (the “opening” formed by a discrete opening or a notch) with a finger. The opening helps the fastening tab to have good handleability on the diaper when the diaper is fixed to a user. A fastening tab having openings or notches, with the side having the notches being attached to the diaper such that the notch forms an “opening”, also distributes forces at the side of the diaper. When the fastening tab is pulled the resulting forces are distributed in at least two directions around the sides of the openings or notches. This improves the fit of the diaper around the waist and/or around the thighs. The opening(s) also improves the visibility of the location of the fastener attachment and increases comfort of the fastening tab.
