Abstract

abstract an apparatus for determining blood clotting capacity comprises an actuator to cyclically move a member within a sample of blood received in a well in a tray and one of a deflection sensor and a position sensor to determine the position of the wetted member upon being acted upon by the actuator. the theoretical position of the wetted member, as determined using a known actuator force and wetted member physical data, is compared to the sensed deflection or position of the wetted member, and the resistance to movement of the wetted member caused by the blood is determined and correlated to a clotting capacity. tradução do resumo resumo patente de invenção: "coagulômetro de sangue e método". trata-se de um aparelho para determinar a capacidade de coagulação do sangue que compreende um atuador para mover cilindricamente um membro dentro de uma amostra de sangue recebida em uma cavidade em uma bandeja, e um dentre um sensor de deflexão e um sensor de posição para determinar a posição do membro umedecido mediante a atuação pelo atuador. a posição teórica do membro umedecido, conforme determinado com o uso de dados físicos de membro umedecido e uma força de atuador conhecida é comparada com a posição ou deflexão captada do membro umedecido, e a resistência ao movimento do membro umedecido causada pelo sangue é determinada e correlacionada a uma capacidade de coagulação.
