  • Patent number: 6423011
    Abstract: A method and apparatus for collecting blood from a fetal scalp. The apparatus includes an elongated housing containing a longitudinally spring-loaded, sharp-pointed, beveled blade disposed at the distal end thereof which can be advanced against the spring bias from the distal end against the fetal scalp. A groove located on an exterior side surface of the distal end of the housing is sized to receive a capillary tube which is resiliently retained on the housing with its distal end proximate a recessed region at the distal end of the housing. The groove may be oriented parallel to the housing, or at an angle thereto, to enhance visualization of blood pooling in the recessed region filling the capillary tube after an incision in the scalp is made using the blade. A light source may be included in or on the apparatus, or on the interior of an amnioscope with which the apparatus is employed. A method of using the apparatus is also disclosed.
