Abstract: An adjustable cervical collar designed to accommodate a broad range of prospective wearers with unique physical attributes, and to restrict the movements of the wearer's cervical spine, including rotation, flexion, extension, and lateral bending. The cervical collar includes a front portion and back portion, which may be adjusted in relation to one other to vary the circumference of the cervical collar. The front portion includes upper and lower plastic portions which may be adjusted to vary the height of the cervical collar, and a front thoracic extender which may be adjusted to achieve a desired restrictiveness of flexion movement. The back portion includes occipital and back thoracic extenders which may be adjusted to achieve a desired restrictiveness of extension movement. The adjustable features may be operated independently of one another. The adjustable features include locking means to ensure that the cervical collar is securely applied to the wearer.

Abstract: An improved cervical collar front portion fabricated from an injection molded thermoplastic resin which when used in connection with a back portion is able to secure a wearer's head and neck. The cervical collar can either be a single piece collar with an integral front portion and back portion or as a two-piece collar with the front and back portions as separate and distinct pieces that are connected together. The front portion incorporates a mandible and chin support which is rigid at the distal ends and flexible at the median to accept and accommodate any wearer's uniquely shaped chin. Furthermore, the chin support central portion is essentially perpendicular to the rest of the front collar portion.

Abstract: A child development sit to stand device comprises a support. At least one fixture is connected to the support for permitting a child to grasp with his hand and raise his own body upwardly under his own ability. A reflective surface is attached to the support for attracting the child to and to use the standing device, facilitating the goal of developing the child's ability to stand. And, a method for assisting in the development of a child to perform a sit to stand movement. The method includes positioning the device into an initial position for the device to be commensurate with the child's ability and, as the child achieves the desired goal of standing, the device is positioned into a more advanced position, increasing the level of difficulty for the child to stand.

Abstract: The present invention relates to a plastics material with self-lubricating action which is particularly suitable for the production of sealing elements for reciprocating compressors, said material comprising a wear-resistant polymer matrix, preferably made from polyketone, within which are dispersed microcapsules containing a lubricating fluid. The microcapsules incorporated into the polymer matrix break up as a result of friction with the contact surface of the sliding partner, resulting in the escape of the lubricating fluid and a consequent reduction in friction.

Abstract: A cervical collar (10) having a front collar portion (12) having a chin support portion (40) and generally conforming to the neck, shoulders, and mandible of a wearer. The front collar portion (12), is fabricated from a soft flexible material and a lateral reinforcing support member (30) disposed in the neck region below the mandible bone of the wearer. The support member (30) is fabricated from a substantially incompressible material.

Abstract: A cervical collar comprising a neckband fabricated from a substantially incompressible plastic material and including a front body section having a first substantially flat shape and being bendable into a second substantially tubular shape, the front body section having a central portion, a laterally extending first side portion, and an opposed laterally extending second side portion. The cervical collar also includes a mandible support fabricated from a substantially and compressible plastic material comprising a centrally located chin support, a laterally extending first side portion, and an opposed laterally extending second side portion and a clip associated with the cervical collar which is moveable from a first unengaged position to a second engaged position in collaboration with a plurality of protrusions located on the cervical collar which define a plurality of predefined positions between the mandible support and the neckband.

Abstract: A cervical collar is provided having a front collar portion fabricated from a substantially incompressible plastic resin and a compressible, flexible foam strip mounted on one side of the front body section. The front collar portion includes a mandible support portion comprising a chin support portion extending transversely in an upper central portion of the front collar portion and a pair of laterally extending jaw support portions which connect at their distal ends to side portions of the front collar portion. Each jaw support portion includes at least one opening formed therein for facilitating bending of the jaw support to conform to a wearer's jaw line.

Abstract: A lightweight plastic cervical collar includes a one-piece injected molded body, of a flexibility and length sufficient to enable the body to be wrapped around the neck of a wearer. One or more absorbent compressible foam strips are attached to an inner side of the body. A front section of the body defining part of a front collar half includes a generally T-shape integrally molded chin support. Upper edge portions of the body are made flexible by the provision of elongated openings and integral hinges formed by molded grooves extending generally longitudinally in the body. A first fabric-strip fastener is adhered to the front body section near one free end while a second, matably configured flexible fabric-strip is extended from the free end of the rear body section to join the adjoining collar ends together. Where the molded body extends around a tracheal opening, transverse reinforcement ridges are molded in the body to prevent collapse.
