Abstract: A duel identification card for use in hospitals and the like and from which the data contained thereon may be transferred to charts, cards and the like. The upper card section contains a transverse slot in one end and, when severed from the lower section, is adapted to be attached to a tether and stored in a patient's wristband. The lower section of the card contains a longitudinal slot near the bottom edge and is adapted to fit into a generally flat rectangular spring steel holder containing protruding lips against which the bottom of the card rests and also contains retention clips in alignment with the protruding lips which clips are configured to secure the card to the holder. The lower card section and holder may be kept at a nurses station or similar place.

Abstract: A composite identification band having multiple identification indicia, the assembly of which comprises a strap with a lower pocket overlying an upper or exposed surface and opening at one end to receive a pressure-adhesive or any other type label adapted to have writing thereon; an upper pocket superimposed on said lower pocket and opening at both ends to receive and store an encoded identification plate. The upper surface of the upper pocket is partially folded back over a portion of said upper surface to form a pocket adapted to receive one or more pressure-adhesive indicia labels. An additional pocket, adapted to receive other indicia, is spaced in longitudinal alignment adjacent to said upper and lower pockets along the strap, an end of the strap nearest the upper and lower pockets contains a stud projecting upwardly from the underside and through the band.

Abstract: Method and apparatus for filtering and permanently separating the serum fraction from the cell fraction of centrifuged blood and the like. A separator head is passed through the serum and is positioned at the interface of the serum and the heavier red cells. As the separator head is positioned serum passes through a self-sealing passage in the separator head and into a collection tube that positions the separator head. Upon withdrawal of the collection tube the passage in the separator head closes sufficiently to effectively block the passage and the serum can be poured from the collection tube. The collection tube can be reinserted to pour off measured volumes of the serum.
