Abstract: A machine-imprintable tape, most advantageously provided in roll or coil form, is disclosed. The tape has lines of weakness constituting tear lines that define a longitudinal series of asymmetric identification bracelets, each bracelet having a generally rectangular imprintable portion, an elongated strap portion at one end of the imprintable portion, and a connecting tab portion at the opposite end of the imprintable portion. The imprintable portion has a width equal to that of the tape; the strap and tab portions are substantially narrower and are arranged along one side edge of the tape to leave removable waste sections extending along only the opposite side edge of the tape. To control advancement of the tape through a printer, each waste section may be provided with a locator opening detectable by an optical sensor of the printer.

Abstract: A patient identification bracelet is composed of a flexible strap and a clasp, the clasp being formed of thermoplastic material and having a base member fixed to one end portion of the strap and a hinged cover member projecting laterally from the strap when the clasp is open. Holding elements project from at least one of the opposable surfaces of the cover and base member for engaging and holding the opposite end portion of the strap when the clasp is closed, and a mating post and socket are provided for locking the clasp in its closed condition. The post and socket are constructed so that the clasp, if forced open, cannot be reclosed. A relatively weak portion of the strap, located between the end portion of the strap that is fixed to the clasp and the identification-receiving portion of the strap, and also located between the base and cover members when the clasp is closed, defines a break-away zone for the strap when pulling forces of predetermined magnitude are applied thereto.
