Microcirculatory skin testing

the PeriCam PSI System is a useful tool for objective and user-independent patch testing. In many cases, a reaction can be detected at shorter times and lower concentrations of the substance compared to visual assessment. The use of finn chambers can facilitate the test setup. The PeriCam PSI System uses laser speckle contrast analysis (LASCA) imaging technique to quantify the reactions.

PeriCam PSI

Based on the laser speckle contrast analysis (LASCA), the PeriCam PSI allows for objective assessment of skin redness or erythema. The large scan area of up to 24 x 24 cm allows for effective examinations and comparable results.

Improving quality of life since 1981

Perimed AB, established in 1981, provides instruments, software and expertise to enable assessment of the microcirculation. We utilize laser Doppler, laser speckle (LASCA) and transcutaneous oxygen (tcpO2 or TCOM), to accurately monitor and quantify blood perfusion and tissue oxygenation in real-time. Our modular PeriFlux System 5000 and PeriFlux 6000, the latest generation of our PeriFlux System, are excellent choices for diagnosing Peripheral Arterial Disease (PAD) and Critical Limb Ischemia (CLI) or for assessing wound healing potential in your vascular patients. Our blood perfusion imagers PeriScan PIM 3 System and PeriCam PSI System, allow you to investigate spatial distribution, for example during cortical spreading depression.
