Wireless, implantable sensor for intraocular eyes on the inside pressure measurement without their own power supply according to the resonance frequency measuring principle

摘要

A patent is requested of a wireless operating sensor (invention) and its various embodiments (subsidiary claims 2 to 10).The sensor is to be implanted in an eye or other provided. It is intended to the in the organ encountered pressure measuring. By means of the flexible configuration (see the main claim and all of the subsidiary claims), he is in a position to determine also a short-term pressure fluctuations.According to an illustration of mr professor pillunat, chef physician the university, college, - eyes clinic dresden (the front in the discussed) of the problem, there is an intraocular, wirelessly operating pressure sensor.The presented sensor and its variants are thus novel.Common measuring principle of all sensor variants is the resonance frequency measurement between the transmitter and the sensor. In this case, the in the production of the sensor output resonance frequency is fixed after implantation, by the pressure changes in the eye. The change in the resonance frequency is measured by removal of energy in the transmitter, as soon as the resonance occurs. The change in the measured resonance frequency is proportional to the intraocular pressure.The presented here, intraoulare eyes pressure sensor and its variants measure the pressure directly located in the eye. The disadvantages of the indirect eyes pressure measurements over the cornea (gold man, perkins, non - contact = air joint employing tonometrics, etc..)this avoids.
