Abstract
Device for non-contact pressure measurement in the anterior ciliary arteries of the eye
Incoming article date: 27.09.2018It refers to the field of medicine, namely, to ophthalmology and to the field of medical instrument making. In the field of ophthalmology, the actual task is to study the state of the vascular system of the eye, the changes of which are observed in many diseases. Currently, there are no non-invasive devices that allow performing an automated direct measurement of pressure in the vascular system of the eye and evaluation of the mechanical characteristics of the vascular wall of the eye vessels. The purpose of the work: the development of a hardware-software complex for eye pneumovazotonometry. The goal is achieved by synthesizing the circuit of a combined measuring device that combines the functions of measuring hemodynamics in the OCA and the IOP level. The complex includes a measuring module and external software for the PC, designed to work with this module. In the measuring module, a microprocessor control system can be distinguished; pneumatic system; ultrasound system; system of video registration; system of indication and control; system of communication with PC; power supply system.
