Abstract: A gun safety lock uses a turnbuckle mechanism and a locking mechanism to lock a breach end of the turnbuckle mechanism in the breach of a gun and lock a barrel end of the turnbuckle mechanism in a barrel of the gun. The gun safety lock is removed from the gun by unlocking the locking mechanism to allow the turnbuckle mechanism to be rotated so that its breach and barrel ends can be removed from the gun.

Abstract: A portable signaling device and method of use in which an elongated reflected strip with a broad and flat profile is held taut in air so that the elongated reflective strip freely twists and rotates along a line formed between a first and a second attachment point of the composite strip when a breeze contacts the broad and flat profile to create a visual signaling display as a result of twisting and rotation of the elongated reflective strip.

Abstract: A rescue line apparatus is configured as a horizontal tether for being readily connected between a door and a portion of the door jamb or other entry location and extending a line as the user moves within the structure. The device allows the user to readily locate their way back for egressing the structure, and can be readily disengaged by the user, which activates a braking system that prevents unit “run-away”. A multi-attach anchor head couples the far end of the line to any desired structure, and has a beacon assembly which outputs a light pattern of sufficient brightness to be seen by the user when visually locating their attachment point within the structure. A multi-element visual indicator is configured for indicating line extension distance, and displaying tether line status. Many options promote safety and a fully cooperative environment.

Abstract: A flexible sheet having an adhesive layer carried on a bottom side. A collection chamber formed in the adhesive layer by the exclusion of adhesive from a central area of the sheet for receiving fluid from the wound. A drainage channel formed in the adhesive layer by the exclusion of adhesive from a selected area of the sheet extending radially outward from the collection chamber to a drain outlet at a peripheral edge of the sheet to drain fluid from the collection chamber. The collection chamber and drainage channel having an open position allowing fluid to flow outward from the collection chamber through the drain outlet, and a closed position collapsed against the skin to prevent fluid intake through the drain outlet. A storage compartment carried by the flexible sheet including a needle and catheter for immediate access in treating a tension pneumothorax.

Abstract: A body harness comprising a waist strap for fastening around the torso of a user; a shoulder strap having a first distal end affixed to a right side of the waist strap and a second distal end affixed to a left side of the waist strap generally opposite from the first distal end; the shoulder strap extending upward from the waist strap in a looped arrangement for fastening over the front of the shoulders and behind the back of the neck of the user so that an apex of the shoulder strap is positioned generally behind the back of the neck of the user when worn; a back strap extending between the apex of the shoulder strap and the waist strap for supporting the back of the user when being dragged; and, a handle carried at the apex of the shoulder strap to facilitate dragging of the user.

Abstract: A method and apparatus are disclosed for saving an exarticulated tooth. The tooth is grasped by its crown, so as not to harm the periodontal membrane. In one embodiment, the tooth is placed in a net which is attached to a basket. The net and basket are immersed in a modified saline solution which preserves the cells of the periodontal membrane. The solution is held in a container which accommodates the net and basket. The container is closed, and the tooth and patient are taken to a dentist. The dentist removes the lid of the container, and lays the lid on a table or other surface, so that the sponge faces upward. The dentist then lifts the basket, with the tooth, out of the solution, and inverts the net so that the tooth falls out onto the sponge. The dentist then grasps the tooth with a forceps and reimplants it in the patient's mouth. In other embodiments, the net is omitted, and is replaced by padding in the container which protecgts the tooth.

Abstract: An adjustable extrication back brace for stabilizing the pelvic area, the wings or illiac crest, the shoulder area and the head so that the spine related to these portions of an accident victim's body can be held in a neutral position before substantial movement can or should be undertaken to remove the victim from the accident scene and in which the back brace comprises cooperating corrugated panels slidably interrelated for longitudinal adjustment, a cervical block positionable on one panel to fit the cervical curve, and a plurality of securing strap anchors spaced along the panels for retaining the victim in position with the back brace aligned against the vetertrael spine or mid-line of the back. The back brace panels are made small to be maneuvered into position where space and the body position makes access difficult.

Abstract: An integral one-piece plastic extraction device for extracting food or other articles from a blocked larynx or windpipe which includes an elongated handle portion and at least one ribbed bowl spoon portion at one free end thereof which is configured, arranged and dimensioned to permit removal of food dangerously lodged in a larynx or windpipe.

Abstract: An extension splint is disclosed as having an elongated frame including a pivoting foot plate and frame brace in order to be readily collapsible as well as being operable in conjunction with means for longitudinally extending the elongated frame above the foot plate in order to apply an extension force to the leg.

Abstract: Silver-heparin-allantoin complex and process for making same is disclosed. The silver-heparin-allantoin complex is prepared by a novel process in either powder or solution form. The silver-heparin-allantoin complex provides a non-thrombogenic, self-sterilizing compound for application to polymeric devices such as prosthetic values, small diameter arterial grafts and the like to avoid thrombus formation and infection of polymeric devices.
