Abstract
A snag-free or safety instrument, such as a wristwatch, having substantially smooth and flowing contours and being free of stems and protrusions eliminates or greatly reduces the potential of state of the art wristwatches to scratch, puncture or tear the skin of persons other than the wearer whom the watch may contact, when worn in normal use and in situations involving possible close contacts as in care giving and sports activities.
Claims12
A safety wristwatch system free of protruding elements and external stems, which comprises:
- (a) a battery operated watch for displaying time having an even surface devoid of roughness and projections;
- (b) at least one pressure sensitive device operatively connected to said watch for control of said watch, said at least one pressure sensitive device being located below and adjacent to elastically deformable indents on the surface of said watch, said indents extending below the surface of said watch;
- and
- (c) a band of flexible material attached to said watch for retaining said watch on a limb of a wearer, said band having an upper surface and a lower surface, said lower surface lying substantially in a first plane so that said band is flush with the limb of the wearer when worn, said upper surface comprising side portions lying substantially in a second plane parallel to said lower surface and a center portion between said side portions raised above said second plane by a distance no greater than the distance between said upper and lower surfaces, said watch, said at least one pressure sensitive device, and said band have a maximum width no greater than 3.25 cm and a maximum height when worn relative to the limb of the wearer no greater than 0.7 cm, said watch, said at least one pressure sensitive device, and said band being without abrupt changes in width and thickness and having even continuous surfaces relative to themselves and to each other to prevent injuries and infection upon contact with persons other than the wearer.

A safety wristwatch system free of protruding elements and external stems, which comprises:
- (a) a battery operated watch for displaying time having an even surface devoid of roughness and projections;
- (b) at least one pressure sensitive device operatively connected to said watch for control of said watch, said at least one pressure sensitive device being located below and adjacent to elastically deformable indents on the surface of said watch, said indents extending below the surface of said watch;
- (c) a band of flexible material attached to said watch for retaining said watch on a limb of a wearer, said band having a surface meeting said surface of said watch with a flush joint and having a band thickness no greater than 0.4 cm;
- wherein said watch, said at least one pressure sensitive device, and said band have a maximum width no greater than 3.25 cm, a maximum height when worn relative to the limb of the wearer no greater than 0.7 cm, and a ratio of maximum height to band thickness no greater than 2 so that said watch, said at least one pressure sensitive device, and said band being without abrupt changes in width and thickness and having even continuous surfaces relative to themselves and to each other to prevent injuries and infection upon contact with persons other than the wearer.

A safety limb-worn instrument system free of protruding elements and external stems, which comprises:
- (a) an instrument selected from the group consisting of a computer, a medical monitoring device, and a watch for displaying time, said instrument comprising a source of power for operating said instrument;
- (b) at least one pressure sensitive device operatively connected to said instrument for control of said instrument, said at least one pressure sensitive device being located below and adjacent to elastically deformable indents near said instrument;
- and
- (c) a band of flexible material attached to said instrument for retaining said instrument on a limb of a wearer, said band having a band thickness no greater than 0.4 cm;
- wherein said instrument, said at least one pressure sensitive device, and said band have a maximum width no greater than 3.25 cm, a maximum height when worn relative to the limb of the wearer no greater than 0.7 cm, and a ratio of maximum height to band thickness no greater than 2 so that said instrument, said at least one pressure sensitive device, and said band being without abrupt changes in width and thickness and having even continuous surfaces relative to themselves and to each other to prevent injuries and infection upon contact with persons other than the wearer.
