摘要:
The present invention provides a system of head and spine protection conceptually different from, and superior to, the traditional free-floating helmet concept, for use in high impact physical activities, such as such as football, hockey, lacrosse, motorcycling, downhill skiing, bobsledding/luge, cycling, snowmobiling, race car driving, factory/construction activities, firefighting, skydiving, and training/battlefield activities by the military and law enforcement officers. The head dome and connection system provides a clear or tinted, impact-proof, projectile-proof bubble over the head and neck, which is secured firmly to the wearer's shoulders and torso via a connection system of straps to a harness, or to the waistline/upper thighs. The head is protected from impact against the inside of the dome by a cushioned cap, secured in place with a chin strap. The head dome can contain, in various embodiments, climate controlling features, solution-treated surfaces to prevent visual obfuscation from fog/ice/water beads, heat resistant construction for firefighting applications, radio/digital communication options, and a self-contained breathing apparatus. The head dome and connection system thus keeps the entire face, head, neck and cervical/upper thoracic portion of the spine free from the injurious impacts from exterior forces, objects and projectiles, while preserving the wearer's freedom of head movement, unobstructed vision, enhanced communication options, and comfort. Inside the head dome, the wearer's head and neck movement and interaction with his or her surroundings are virtually as unimpeded as if there were no head protection whatsoever.

A seal assembly includes a first seal, a second seal, and a positioning element. The first seal includes at least one longitudinal slot therein. The second seal includes at least one longitudinal slot therein and is positioned coaxially with the first seal. The positioning element is positioned coaxially with the first seal. The at least one longitudinal slot of the first seal is offset from the at least one longitudinal slot of the second seal in a radial direction from a longitudinal axis of the seal assembly. The seal assembly can be integrated with a closing valve. The seal assembly can also be integrated with a capsule.

A head restraint assembly includes a curved support member for upwardly and forwardly deploying a headrest. The support member is selectively locked and unlocked to alternately maintain the headrest in a retracted position or deploy the headrest. A vehicle impact sensor signals the release of the support member when a vehicle impact is sensed. The headrest is deployed quickly and effectively until it reaches its potential full deployment, or until an occupant's head contacts the headrest.
摘要:
One aspect is a method for inserting an instrument into the gastrointestinal tract of a mammal, by emplacing at least a portion of a flexible liner to form within the intestine an inner tube within an outer tube, the inner tube defining a lumen lying within the intestine and having a distal end accessible via the anal opening from outside the body of the mammal, and thereafter passing the instrument into the lumen via its distal end. Another aspect is the combination of an elongate evertible liner, a liner support chamber having a proximal port and a distal port, the liner having its two ends attached respectively at the ports, and a pressurizer for increasing the pressure within the chamber to cause the liner to be everted, the liner comprising a material characterized by having a wall thickness to diameter ratio and a zero strain elasticity modulus whose product is less than 4.0 lb/inch.sup.2, preferably less than 1.0 lb/inch.sup.2, and a wall thickness to diameter ratio and a 100% strain modulus of elasticity whose product is greater than 0.5 lb/inch.sup.2, preferably greater than 2.0 lb/inch.sup.2. In another aspect, a layer of lubricous material, such as polyvinylpyrrolidone (PVP), is directly bonded to a surface of a layer of elastomeric material (such as polyurethane) without the use of adhesive materials between the layers. The resultant PVP-coated sheet is formed into the flexible liner. Yet another aspect is several devices for emplacing the liner in the intestine.

A seal assembly includes a first seal and a second seal and positioned in the first end element. The second seal can include at least one longitudinal groove therein and have members connected thereto. A stopper member is coaxially positionable within the second seal and the first seal and a lubricant can be positioned between the stopper member and the second seal. The seal assembly can also be integrated with a capsule for removable insertion within a tubular member.
摘要:
A surgical device for endoscopic surgical procedures capable of preventing injuries to internal organs during insertion. The surgical device can include one or more of the following: a multiple system of sharp blade edges, a mechanical tissue protection device that includes a series of thin plastic guards sliding along the sides of the planar knives and having an angle between their edges smaller than that of the cutting knife edges, one or more fixed conical deflectors to expand the cut tissue passage leaving the guards to contact tissue contact only at their tips, an insufflation passage configured to transport fluid into the body cavity during penetration, a locking system for the guards that prevents accidental reuse of the cutting features, and/or an ergonomic design which facilitates handling.
摘要:
A flexible, articulable column having a central cable tensioning member with a series of ball and socket members strung on the cable forming articulable joints. Each socket member has at least one conical opening with internal teeth engagable with a ball which is made of an elastomeric polymer. When the cable is tensioned, the sockets move toward each other and the balls are indented by the teeth of the socket. The column thus becomes rigid. Releasing the tension returns the column to the flexible state.
