A medical analyzer and coagulation profiler performs various interrogations on specimens. A motor with reduction gearing moves and a video camera observes the samples, the cartridges or parts thereof. Changes in images are compared and recorded with a central processor that controls a display. Power supply, temperature controller, motor and gearing are mounted in a box which attaches to a smartphone. The smartphone provides the video camera, illumination and central processor that control the movement, temperature and display. The device makes testing simpler for small hospitals, clinics, ambulances, remote locations and individuals and controls a number of parallel or serial devices operating simultaneously or sequentially. A cartridge insertion actuates a circular motion to generate a blood profile based on changes. Change is analyzed with a video camera and processor such as in a smartphone and is plotted to show an amplitude and time. A smartphone provides a specific movement pattern.

The present invention relates to a device for measuring rheological properties of a high-viscosity material and a measurement method thereof in which, while a discharger of the present invention is completely blocked, a change in pressure of the high-viscosity material due to a change in the number of rotations of a first screw is measured, thus having an advantage of being able to precisely and reproducibly measure the viscosity.

A process for evaluating rheological characteristics of an injectable gel including measuring the flexibility, wherein the flexibility is evaluated by measuring the strain at the crossover point of the amplitude sweep. The process may include subjecting an injectable gel to oscillating mechanical stresses to determine G′ and G″ as a function of strain (γ) in an amplitude sweep, determining the crossover point as the point at which G′ and G″ have the same value, determining the strain γ.sub.cross at the crossover point, and determining the flexibility of the injectable gel as γ.sub.cross or proportional to γ.sub.cross. Further, a method of comparison of dermal fillers by measuring their flexibility and a method of evaluation of dermal filler behavior in human skin by measuring the flexibility.

A method for determining the sticky point of powder samples includes introducing a sample into a first measuring part, placing a second measuring part above the first measuring part to delimit a sample chamber, using a motor to drive the measuring parts relative to one another, using a force application unit to exert a force on the sample normal to a rotational plane of the measuring parts, using a measuring unit to record a torque or shear stress of the sample between the measuring parts, using a temperature-control unit or oven to apply a temperature profile to the sample while measuring the torque or shear stress, and supplying recorded measured values of the torque or shear stress and the sample temperature at measuring points to an evaluation unit. The evaluation unit determines the sticky point from the measured values of the torque or shear stress and the temperature.
