Abstract

Portable coagulation monitoring devices, systems, and methods are disclosed. Namely, a test cartridge is provided for use in a portable coagulation monitor (PCM) device. Further, the test cartridge comprises two glass-filled thermoplastic polymer plates and a disposable blood introduction device. The two glass-filled thermoplastic polymer plates are arranged substantially in parallel with a small gap therebetween for receiving a sample of blood to be tested. Using the PCM device, the two glass-filled thermoplastic polymer plates can be moved linearly relative to each other. Methods of measuring coagulation response in a blood sample using the test cartridge and the PCM device are provided. A method of introducing blood into the test cartridge using the disposable blood introduction device is provided.

Claims34

Dependent claims

A device for measuring coagulation response in a blood sample, the device comprising a test cartridge comprising:

a first member having a first flat surface;
and
a second member having a second flat surface positioned to face the first flat surface to define a space therebetween sized to allow a sample of blood to be introduced into the space to contact the first flat surface and the second flat surface, the first member configured to linearly move and oscillate to cause the first flat surface to oscillate relative to the second flat surface to cause the sample of blood to coagulate and bind thereto, the second member configured to move from a stationary configuration responsive to the movement of the first member via the coagulated sample of blood, thereby changing mechanical displacement between the first and second members for measuring a coagulation response of the sample of blood.

Dependencies are inferred from the claim text.
