|| List of recent Prothrombin Time-related patents
|Low volume assay apparatus|
Apparatus (1) for determining a property of a sample. The apparatus has a chamber (11, 13) for receiving at least a part of the sample and contains a rotor (15) adapted to rotate within the chamber (11, 13).
|Novel method of prognosis associated with cases of postpartum hemorrhage|
The present invention relates to an in vitro method of prognosis for the arrest of bleeding in a patient suffering from postpartum haemorrhage in the absence of an invasive procedure, comprising the following steps: (a) determining, using a biological sample from said patient, the plasma fibrinogen concentration, the blood troponin concentration and also the prothrombin time; (b) studying at least two clinical markers for said patient, selected from the group comprising heart rate and the presence of placentation abnormalities; (c) calculating a score z according to the following equation: z=a+b+v+d+e; where a is associated with the existence of placentation abnormalities in said patient, with a being 0 when no placentation abnormality is observed in said patient and a being 1 when one or more placentation abnormalities are observed in said patient; where b is associated with the heart rate of said patient, with b being 0 when the heart rate of said patient is less than or equal to 115 bpm (beats per minute) and b being 1 when the heart rate is greater than 115 bpm; where c is associated with the plasma fibrinogen concentration of said patient, with c being 0 when said concentration is greater than or equal to 2 g/l and c being 1 when said concentration is less than 2 g/l; where d is associated with the blood troponin concentration of said patient, with d being 0 when said concentration is less than the detection cut-off and d being 1 when said concentration is grater than or equal to the detection cut-off; where e is associated with the prothrombin time (pt) of said patient, with e being 0 when said prothrombin time is greater than or equal to 50% and e being 1 when said prothrombin time is less than 50%; where a score z of greater than or equal to a value of 2 is an indication of the need to perform an invasive procedure in order to stop the bleeding in said patient suffering from postpartum haemorrhage.. .
|Electrochemical blood test strips and diagnosis systems using the same|
Electrochemical blood test strips and diagnosis systems are presented. An electrochemical blood test strip for measuring hct % and prothrombin time includes an electrode plate having electrode circuit patterns on an insulator substrate; a separation plate disposed on the electrode plate defining a blood sample region, a channel and three reaction regions; and a cover plate disposed on the separation plate having a blood sample inlet and vents.
|Tetrakis[bis(dihydroxyphosphoryl)methyl]calixarene or its sodium salt thereof as fibrin polymerization inhibitors|
There is proposed a chemical compound of 5,11,17,23-tetrakis[bis(dihydroxyphosphoryl)methyl]calixarene and a sodium salt thereof, which can be used as antithrombotic agents. A highly specific inhibiting effect of the aforementioned calixarenes on the fibrin polymerization has been identified.
