Abstract
A blood parameter measurement system has a monitor configured to provide an oxygen saturation measurement based upon the absorption of two wavelengths of optical radiation by a tissue site. A software upgrade is installable in the monitor so as to enable the monitor to operate in conjunction with a multiple wavelength sensor. A wavelength controller is adapted to the upgrade so as to drive the sensor.
Claims28
A blood parameter measurement system comprising:
- a monitor configured to provide an oxygen saturation measurement based upon the absorption of two wavelengths of optical radiation by a tissue site;
- a software upgrade installable in said monitor so as to enable said monitor to operate in conjunction with a multiple wavelength sensor;
- and
- a wavelength controller adapted to said upgrade so as to drive said sensor.
1 more element
A blood parameter measurement system comprising:
- a multiplicity of emitters configured to transmit at least three distinct wavelengths of optical radiation into a tissue site;
- at least one detector configured to receive said radiation after attenuation by said tissue site and to generate a corresponding detector signal output;
- and
- a wavelength controller having a drive signal input and a sensor control output adapted to sequentially enable said emitters.
1 more element
A blood parameter measurement method comprising the steps of:
- communicating a drive signal from a monitor to a sensor;
- synchronizing said sensor with said monitor;
- sequentially enabling a plurality of emitters of said sensor;
- and
- communicating a sensor signal from said sensor to said monitor.
2 more elements
A blood parameter measurement system comprising:
- a multiple wavelength sensor means for illuminating a tissue site with at least three wavelengths and detecting a corresponding tissue site response;
- a software upgrade means for enabling a pulse oximetry monitor to drive said sensor and process a corresponding sensor signal;
- and
- a wavelength controller means for interfacing between said software upgrade means and said multiple wavelength sensor means.
