  • Patent number: 10299941
    Abstract: A prosthetic arm apparatus comprising a plurality of interconnected segments that provide the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connected to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments includes an actuator providing a portion of the movement capability, and each segment may operate independently of each of the other segments of the plurality of segments. One segment of the plurality of segments includes a non-backdriving clutch that transfers power from the actuator to an output interface of the segment when the actuator is actuated to generate movement of the output interface in either of two opposing directions and prevents backward transfer of power from the output interface to the actuator of the segment in both of the two opposing directions.

  • Patent number: 10292838
    Abstract: A prosthetic arm apparatus including a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a prosthetic support apparatus that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user.

  • Patent number: 10238548
    Abstract: A water-resistant orthopedic undercast sleeve that includes a tubular sheet material formed of extruded filaments having water-resistant properties and a thickness sufficient to provide both cushioning and moisture transport in a single layer between a cast and a limb onto which the sleeve is applied. The water resistant properties are achieved by at least one process, including a water-resistant filler, finish or coating applied to the filaments during extrusion, applying a water resistant finish to the finish during extrusion, applying a water resistant finish to the filaments during a subsequent spinning process, or coating the filaments with a water-resistant finish in a separate process. Moisture egress channels are formed in the sheet material for transporting moisture away from the limb, longitudinally along the length of the sleeve, and out of the space between the sleeve and cast.

  • Publication number: 20190083293
    Abstract: A medical bandaging product that includes a flexible medical material including an elongate knitted fabric, a reactive system, and microspheres. In certain aspects, a component of the reactive system is homogeneously impregnated into or coated throughout the flexible medical material without being encapsulated in the microspheres such that the reactive system remains stable and non-activated in the absence of an activating agent, and hardens upon activation by exposure to the activating agent to form a rigid, self-supporting structure. In this aspect, the microspheres are homogeneously impregnated into or coated throughout the flexible medical material, the microspheres encapsulate an activating agent and are configured to release the activating agent to form the rigid, self-supporting structure.

  • Patent number: 10051841
    Abstract: A retractable pet leash assembly includes a housing, a spool, a leash and a braking assembly. The spool is disposed inside the housing and biased by a spring and includes braking notches. The leash is wound about the spool. The braking assembly includes a pawl, a pawl spring and an operating member. The pawl selectively engages the braking notches, the pawl spring biases the pawl towards engagement with the spool. The operating member moves the pawl between first and second positions to move the pawl into and out of the path of the braking notches. The operating member has a pawl non-engaged position in which the pawl is in the first position, a first pawl engaged position in which the pawl is in the second position, and a second pawl engaged position in which the operating member is retained while the pawl is in the second position.

  • Patent number: 10034460
    Abstract: A retractable leash system includes a housing, a leash, a spool, and a brake. The spool is attached to the leash and disposed within the housing. The leash is configured to be rotationally biased so as to urge the leash into a spooled configuration. The brake includes an operating button, a compression spring, and a brake member coupled to the operating button. The brake member is associated with the compression spring and is configured to engage the spool by operation of the operating button, such that, when the brake is engaged, the spool is prevented from rotating in an unspooling direction and capable of rotating in a spooling direction.

  • Publication number: 20170360591
    Abstract: An undergarment for use with a cast tape to form a hip spica cast, such as a pantaloon-type hip spica cast. The cast includes at least one layer of a 3D spacer synthetic padding material formed into a fabric of monofilament yarns and fabricated into an anatomically correct undergarment structure for being positioned around a torso and residing directly against the skin of a hip spica cast patient.

  • Patent number: 9723816
    Abstract: A two or more subject retractable leash, and methods of use thereof, is disclosed, which includes a roll-back feature on each retractable leash. The leashes may be locked in place by engaging a single lever. The leashes retract regardless of whether the spools are locked or unlocked. Each leash retracts independently of the other leashes, such that a dual leash may be used to walk one subject. In some embodiments, a single subject retractable leash includes a roll-back feature that provides and allows for leash retraction, whether or not a brake associated with a spool thereof is engaged.
