  • Publication number: 20220240841
    Abstract: A pressure monitoring system and method for warning a patient or caregiver that soft tissue pressure has exceeded some predetermined level that over time would necessitate moving the patient to prevent or at least reduce a risk of soft tissue damage. The pressure monitoring system and method utilize a dressing assembly adapted to be applied to or near a surface of the patient's body and generate electrical outputs corresponding to soft tissue pressure sensed at the surface. The dressing assembly includes a pocket formed therein for removable, secured and protected insertion of one or more sensors.

  • Publication number: 20210169401
    Abstract: Pressure monitoring methods and systems for warning a patient or caregiver that soft tissue pressure has exceeded some predetermined level that over time would necessitate moving the patient to prevent or at least reduce a risk of soft tissue damage. The methods and systems entail the use of a pressure sensing unit adapted to be applied to or near a surface of the patient's body, and a sensor associated with the sensing unit to generate electrical outputs corresponding to soft tissue pressure sensed at the surface. The electrical outputs are wirelessly monitored over a preselected time period to generate a cumulative output signal based on the electrical outputs and corresponding to whether or not the soft tissue pressure has exceeded a predetermined pressure level during the preselected time period. An alarm is generated if the cumulative output signal exceeds a predetermined cumulative threshold until the soft tissue pressure drops below the predetermined pressure level.

  • Patent number: 10334905
    Abstract: A protective boot adapted to be worn by individuals when lying in a reclining position. The boot has leg and forefoot portions that provide foot and lower leg support for a wearer while suspending the wearer's heel. The boot may include low-friction materials at an exterior surface of its leg and forefoot portions and at a continuous rim separating the exterior surface from an interior surface of the body, in which case the boot also preferably includes a system for adjustably closing an anterior opening in the forefoot portion by drawing lateral regions of the forefoot portion inward and together. The boot may additionally or alternatively include an L-shaped backplate having portions located at the leg and forefoot portions of the body and adapted to inhibit buckling of the boot within the leg and forefoot portions.

  • Patent number: 8535246
    Abstract: A pressure monitoring method and system for warning a patient or caregiver that soft tissue pressure has exceeded some predetermined level that over time would necessitate moving the patient to minimize or prevent soft tissue damage. The method and system entail the use of a pressure-sensitive pad assembly adapted to be applied to a surface of the patient's body and generate electrical outputs corresponding to soft tissue pressure sensed at the surface. The system monitors the electrical outputs over a preselected time period and generates a cumulative output signal based on the electrical outputs and corresponding to whether or not the soft tissue pressure has exceeded a predetermined pressure level during the preselected time period. The system generates audible and visual warnings if the cumulative output signal exceeds a predetermined cumulative threshold until the soft tissue pressure drops below the predetermined pressure level.

  • Patent number: 8444584
    Abstract: A compression hose adapted to be worn to cover at least the calf and foot of a leg of an individual, and a method for medically treating the individual with the compression hose. The compression hose includes connected leg and foot portions formed of an elastic fabric material and adapted to cover, respectively, the calf and foot of the individual. A heel opening is located between the leg and foot portions so as to be located in the compression hose to coincide with the heel of the leg of the individual. The heel opening has a perimeter defined by a stitch that limits stretching and expansion of the heel opening relative to stretching and expansion of the leg and foot portions of the compression hose.

  • Patent number: 7758481
    Abstract: A dynamic hip stabilizer utilized to reduce the risk of postoperative and recurrent traumatic hip dislocations. The hip stabilizer includes a pelvic girdle, at least one thigh cuff, and one or more elements for generating an elastic tensile force between the girdle and cuff. The girdle has an upper portion configured for defining an upper opening for the wearer's waist, a lower portion configured for defining a lower opening for the wearer's hips, and a posterior portion configured for engaging the wearer's lower back. The hip stabilizer further includes one or more elements for engaging the wearer's shoulders to limit movement of the girdle toward the thigh cuffs caused by the elastic tensile force, and one or more elements for stiffening the posterior portion of the girdle.

    Abstract: A dynamic hip stabilizer utilized to prevent postoperative and recurrent traumatic hip dislocations. The stabilizer includes a pelvic girdle defining an upper opening for the wearer's waist and a lower opening for the wearer's hips, at least one thigh cuff defining an upper opening for a thigh of the wearer and a lower opening for a lower region of the wearer's thigh, and elastic cables attached to the pelvic girdle and the thigh cuff and extending therebetween in a longitudinal direction of the stabilizer. The stabilizer further includes channeling features associated with the pelvic girdle for guiding and controlling movement of the cables in directions transverse to the longitudinal direction of the stabilizer. The stabilizer may optionally include lateral extensions that connect the girdle to each thigh cuff.

  • Patent number: 7458948
    Abstract: A heel-supporting boot capable of supporting a leg of a person in a supine reclining position, such as a bedridden patient, to reduce the risk of bed sores, foot drop, etc. The boot includes a flexible and compressible body having leg and forefoot portions, a continuous cavity within the leg and forefoot portions, an anterior opening to permit a patient's foot and leg to pass therethrough into the cavity, oppositely-disposed lateral regions defined by the leg portion and separated by the anterior opening, and an adjustable closing feature for closing the anterior opening with the lateral regions. A stitch pattern is disposed along at least the forefoot rim, and preferably also the lateral rims, bounding the anterior opening. The stitch pattern is sufficiently close to the forefoot rim and optionally the lateral rims to structurally reinforce the forefoot rim and inhibit elastic and plastic deformation of the forefoot portion.

  • Patent number: 7052479
    Abstract: A traction device for applying traction to a patient's leg while supporting the patient's foot to avoid foot drop and heel or lateral malleolar pressure ulcers. The device includes a body having forefoot and lower leg portions, a continuous cavity within the forefoot and lower leg portions, and an anterior opening sized to permit a patient's foot and lower leg to pass therethrough into the cavity. The body supports the patient's lower leg so that the patient's heel is suspended within the cavity. Elements adjustably close the anterior opening and traction straps are removably attached to lateral regions of the body and extend from the forefoot portion. The interior surface of the cavity provides a sufficiently high friction interface with the patient's lower leg to prevent sliding of the body on the lower leg when full traction loads are applied through the traction straps.

  • Patent number: 6962011
    Abstract: A cast shoe sized and configured to be worn on a casted foot. The shoe includes an air-insufflated outer sole formed of a resilient polymeric material to absorb impact. The outer sole has a heel portion of substantially uniform thickness, a tapered toe portion that is thinner than the heel portion, an upper surface, and a lower surface that has a tread pattern and is curved as a result of the tapered toe portion to provide a single rocker bottom function in gait. An inner sole overlies and is attached to the upper surface of the outer sole. A strap located adjacent the heel portion of the outer sole is provided for securing the cast shoe to a casted foot. The outer and inner soles lack any rigid member that would stiffen the sole.
