STERILITY COVER FOR MEDICAL DEVICE SURFACE

摘要

A disposable bag for maintaining sterility of a medical instrument having a detection mechanism and cable extending from the detection mechanism,;wherein the bag comprises:;a pair of flexible sheets comprised of a polymeric material,;the pair of sheets being arranged in parallel to each other and sealed along opposing lateral sides that extend longitudinally from a top end to a bottom end,;the cable having a selected length such that upon insertion of the detection mechanism through the enclosed interior chamber of the bag, the cable extends longitudinally through the open bottom end,;the bag being adapted to be attached to at least a portion of the cable that extends from the detection mechanism downstream toward the open bottom end.

1. A disposable bag for maintaining sterility of a medical instrument, the instrument comprising an elongated cable having a cable length and a detection mechanism for engagement with an examination surface of a subject to be examined for a signal generated by the subject through the examination surface, the elongated cable being interconnected to the detection mechanism at a proximal end of the cable for transmitting a signal generated by the detection mechanism to a distal end of the cable,
wherein the bag comprises: a pair of flexible sheets comprised of a polymeric material, the sheets having a thickness through which the detection mechanism can sense the signal generated by the subject when the detection mechanism is held in engagement against the examination surface with one of the sheets disposed between the detection mechanism and the examination surface, the pair of sheets being arranged in parallel to each other and sealed along opposing lateral sides that extend longitudinally from a top end to a bottom end, the top end being sealed and the bottom end being open such that the sheets form an enclosed interior chamber with an open longitudinal bottom end for insertion of the detection mechanism into and longitudinally through the enclosed interior chamber a selected insertion distance from the open bottom end toward the sealed top end, one of the pair of sheets being longer longitudinally than the other of the pair sheets forming a flap that extends from the one longer sheet to a longer bottom edge that extends longitudinally beyond a shorter bottom edge of the other of the pair of sheets, the bag having a selected longitudinal length relative to the cable length such that upon insertion of the detection mechanism through the enclosed interior chamber along the selected insertion distance, the cable extends longitudinally from the detection mechanism through the enclosed interior chamber and further through the open bottom end to at least the longer bottom edge of the one longer sheet, the flap being adapted to be attached to at least a portion of the cable that extends from the detection mechanism to at least the longer bottom edge such that the detection mechanism is held within the enclosed interior chamber.
