A blood extraction device ( 100 ) and method for withdrawing a controlled number of drops of blood from a patient, in whom there is created an incision of such dimension that blood does not freely flow therefrom. A release unit ( 160 ) urges drops of blood to flow from the incision, for example by applying a vacuum, and a disabling unit ( 145, 146, 170 ) is coupled to the incision unit for disabling the release unit when a predetermined number of drops of blood have been withdrawn. |
