A blood collection device (20) for collecting a blood sample from a foetal scalp comprises a blood collector preferably in the form of a capillary tube (22) and a cutting member (24) for incising the foetal scalp which is movable between a primed condition and a cutting condition. The blood collection device (20) includes a biasing arrangement (26) to urge the cutting member (24) from the primed condition to the cutting condition, the capillary tube (22) being arranged to collect blood from the foetal scalp when the cutting member (24) is moved to the cutting condition. The biasing arrangement (26) is preferably also operable to urge the cutting member (24) from the cutting condition to a retracted condition. The device (20) preferably also includes a blood detection system for detecting the présence of blood in the capillary tube (22). |
