Embodiment Construction

[0046] figure 1 In an exemplary embodiment of the first aspect of the invention it is shown that the physiological parameter monitoring system (for example with reference to Figure 2 to Figure 4B The passive sensing device 100 for a contact lens used in the examples described in detail). In this embodiment, the passive sensing device 100 is a resonant circuit used in a contact lens for detecting changes in a physiological parameter as the contact lens is worn. In particular, the passive sensing device 100 may be used in contact lenses to monitor changes in intraocular pressure, eg for patients suffering from glaucoma.

[0047] Such as figure 1 As can be seen in , the passive sensor 100 includes an inductive element (here, an inductor 101), and at least one capacitive element (here, a plurality of capacitors 121, 122, 123, 124, 125, and 126), all of which are coplanar of. In other words, before the subsequent step of incorporation into a contact lens, the passive sensor 100 ...

Abstract

The invention relates to a passive sensing means (100) for a contact lens of a physiological parameter monitoring system, for detecting variations of a physiological parameter, in particular intraocular pressure, the passive sensing means (100) forming a resonant circuit comprising an inductor (101) and at least one capacitor (121, 122, 123, 124, 125, 126). The inductor (101) and said at least one capacitor (121, 122, 123, 124, 125, 126) are coplanar in only one layer. The invention also relates to a corresponding physiological parameter monitoring system.

Description

technical field [0001] The present invention relates to the field of physiological parameter monitoring systems, in particular for monitoring changes in intraocular pressure. The invention particularly relates to passive sensing devices for use in physiological parameter monitoring systems and corresponding physiological parameter monitoring systems. Background technique [0002] Intraocular pressure is one of the physiological parameters that allows the diagnosis and monitoring of ocular diseases such as glaucoma. More recently, portable and non-invasive sensing devices and methods have been developed in order to measure diurnal variations in a patient's intraocular pressure, avoiding invasive surgical procedures in which sensing devices need to be implanted in the patient's eye. Furthermore, the portability of the non-invasive system has the advantage that the patient no longer needs to be immobilized in a hospital or clinic, but can now constantly monitor physiological p...
