Embodiment Construction

[0025] Figure 1 shows an in-ear (ITE) physiological measurement device 2 (hereinafter referred to as "ITE device") for measuring one or more physiological signals (e.g., blood pressure, pulse, blood oxygen, perfusion, body temperature, respiration, ...) from within the ear canal. 2"). The ITE device includes a structure 4 that is inserted into the ear canal. The structure 4 is sized to enter the ear canal at a suitable depth and to accommodate various shapes of the ear canal (eg, different degrees of curvature). That is, the diameter of the structure 4 is smaller than the diameter of the ear canal. In a preferred embodiment, the structure 4 protrudes into the ear canal so that the end is placed near the bony region of the ear or other quieter regions of the ear canal.

[0026] The end of the structure 4 located in the ear canal comprises an annular inflatable balloon 6 . An inflatable bladder 6 surrounds the ends of the structure 4 (as shown) or a suitable portion thereof. ...

Abstract

An in-the-ear (ITE) physiological measurement device (2) includes a structure (4) formed to be easily inserted into ear canals of various shapes and sizes. An inflatable balloon (6) surrounds the end of the structure (4) to be placed in the ear. Optionally, a mushroom-shaped tip (22) is attached to the end of the structure (4) and carries a plurality of sensors (8). Inflation of the balloon (6) radially expands the tip (22) to place the sensor (8) adjacent to the vascular tissue in the ear canal. Once in place, one or more sensors (8) sense physiological signals from vascular tissue and bone structures.

Description

technical field [0001] The following pertains to monitoring physiology. It is particularly applicable to an in-ear structure that is inserted into the ear canal for proper positioning of one or more physiological sensors within the inner ear to obtain information representing physiological phenomena including, for example, blood pressure, respiration, perfusion index, blood oxygen , pulse rate and body temperature. Background technique [0002] Physiological signals can already be measured from within the ear. However, there is no multiparameter physiological measurement device that measures blood pressure non-invasively from within the ear. Examples of barriers to such development include the varying size and shape of the human ear canal from person to person, the inability to strategically place sensors within the ear canal for optimal reception of physiological signals, and the inability to protect sensing devices while measuring Physiological signals are free from con...
