Blood sampling device

A blood sampling device for providing a blood sample in combination with a cuvette for receiving and performing a blood coagulation test on said blood sample, the combination therewith comprising:

• a lancet for creating an incision in a patient's skin that causes the patient to bleed;
• a receptacle assembly coupled to said lancet, said receptacle assembly having a receptacle member for receiving a predetermined volume of blood from the patient therein and a receptacle attachment member for coupling said receptacle assembly to said lancet, said receptacle member having a conical-shaped reservoir member extending up from an unitary with a surface of said receptacle attachment member, said conical-shaped reservoir including a first opening through which blood can enter said receptacle member and a second opening through which said blood sample can be drawn from said receptacle member,
• a cuvette comprising a transparent member having a plurality of conduits for receiving and performing said blood coagulation test on said blood sample and,
• a channel common to said plurality on conduits through which said predetermined volume of the blood sample can be drawn from said second opening of said receptacle member into each of said conduits, of said cuvette,
• a first compound contained within a first of said conduits, wherein said first compound reacts with the blood sample within the first of said conduits to produce a first coagulation characteristic, and
• a second compound contained within a second of said conduits,
• wherein said second compound reacts with the blood sample within the second of said conduits to produce a second coagulation characteristic.
