Title:
PULSE OXIMETER AND CASING FOR ANCHORING A SENSOR
Document Type and Number:
WIPO Patent Application WO2006079862
Kind Code:
A3
Abstract:
The invention is a pulse oximeter sensor-head (8) which is composed of electrical units and comprises at least two light sources (1, 2) of different wavelengths to emit light into the part of the body (9) under examination and a light detector (3) to sense the light eigther transmitted through or reflected from the part of the body (9) under examination, further comprises a control circuitry (4) connected to each electrical unit or at least to the light sources (1, 2) and the light detector (3), a data collector and A/D dataconverter circuitry (5) connected to the output of the light detector (3), a wireless data communication circuitry (6) connected to the output of the data collector and A/D dataconverter circuitry (5), and a current source (10) to ensure the power supply of the pulse oximeter sensor-head (8). The invention is also a measuring system comprising said sensor-head (8) and a measuring method with said sensor-head (8). The invention relates also to a method and a casing (11) for anchoring a sensor-head (8) where the sensor- head (8) is fixed mechanically in a bell-jar-like casing (11) by means of structural element (11b) of said casing (11), said casing (11), having an internal air space (12) and a flange (14), is placed together with the sensor- head onto the surface of the body (9) so that the flange (14) together with the surface forms an airtight sealing, and a decrease of pressure is generated in said air space (12) during the process of placing the sensor-head (8) onto the surface of the body (9).
