DEVICE FOR MEASURING tremor of the fingers

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medical equipment and may be used in biochemical examinations, in sport, in neurophysical examinations for the purpose of early diagnosis of diseases of various functional systems, as well as for the purpose of the occupational fitness. An apparatus comprises a recording unit, a data processing unit and a bioobject positioning unit. The positioning unit comprises a hand support representing an end-capped C-profile made of a light metal and integrating along the full length an adjustment screw with a handle, a palm support and a stopper element. The palm support consists of a bushing with a screw gear inside the C-profile, a pin attached to the bushing and an ergonomic nut screwed on the pin. The recording and processing units are built in the same body which is rigidly perpendicularly attached to the hand support. The recording unit comprises an infrared laser for bioobject irradiation, and a photo camera for high-speed shooting of the object surface in infrared light. The processing unit comprises a digital signal processor connected to a PC via USB 2.0.;EFFECT: use of the invention enables higher accuracy of tremorogramms, producing frequency, amplitude and pattern of two-axis motion with high accuracy and enables further processing.;4 dwg
