Abstract: An anti-shock system for a catheter line inserted in a patient's body. The system includes a spring structure, a base and cover forming a housing with a catheter line entry port and exit port, the spring structure disposed within the housing. A first portion of a catheter line is positioned within the housing, with a distal end portion extending out the exit port, and a body entrance portion extending from the entry port. The spring structure is operatively coupled to a loop of the line and configured to absorb a pulling force exerted on the distal end by a spring action on the loop, without transmitting the pulling force directly to the body entrance portion of the catheter line and thereby prevent undesired migration of the catheter line within the patient's body.

Abstract: An embodiment of an adjustable cervical collar system includes a collar body and a chin support structure assembled together, about respective pivots at opposed ends, for pivotal movement about a pivot axis so that the angle subtended by the collar body and chin support structure can be adjusted. The collar body and chin support structure can be locked in a selected position by a locking mechanism. A release mechanism permits the wearer to release the locking mechanism using one hand, and the angular position of the chin support structure relative to the collar body is changed manually. When the release mechanism is released, the locking mechanism automatically locks the chin support in the new position. A neck strap is detachable from the chin support structure and the collar body, and its length is also adjustable.

Abstract: A wound dressing assembly for a surgical tube or other device entrance into the body includes a cover layer, with adhesive on the outer perimeter of the underside of the cover layer to attach the wound dressing to the patient's body, an absorbent ring secured to the underside of the cover. An interior clear window allows the nurse or other medical personnel to view the wound site through the window for inspection for infection or bleeding. A port is formed in the window area to allow a tube or other device to pass through the wound dressing.

Abstract: The present invention provides a cervical collar with a rack and pinion adjustment mechanism. The rack moves a chin support member, which raises and lowers a chin piece. Independently, the present invention provides methods and mechanisms in which the chin support can angulate independently of the collar body. Such angulation is preferably accomplish by pivotally supporting the chin piece on the racks, or on the left and right chin support pieces. Thus, in a preferred class of embodiments, the collar has a pivot for the chin support pieces relative to the collar body, and an other pivot for the chin piece relative to the chin support pieces.

Abstract: A protective case for a portable digital media device includes a hinged element and an aperture registered with an input element for such device, to provide protection against inadvertent damage to the device, to selectively operate as a stand to maintain the device in an upright position, and enable user access to the input element when the case is closed.

Abstract: A throwing disc with changeable aerodynamic characteristics for use with human hands having fingers, comprising a first member which is circular and has a diameter and a thickness substantially less than the diameter of the first member. The first member has first and second surfaces and has an outer margin and a downward depending lip adjoining the outer margin. A second member is centrally disposed with respect to the first member. The first and second members are interconnected so the first and second members can move in unison as the throwing disc is thrown. The second member is movable with respect to the first member for changing the aerodynamic characteristics of the throwing disc.
