Embodiment Construction

[0022] refer to figure 1 Alternatively, pulse oximetry monitor 10 may only monitor pulse and oxygen saturation levels, or pulse oximetry monitor 10 may be a much larger monitor system with many leads to monitor many other physiological conditions. The monitor 10 includes a digital display 12 for displaying blood oxygen saturation and pulse rate values, and may also include a graphical display 14 for displaying the waveform of the pulse (ie, a plethysmogram) resulting from cardiac activity. Optionally, an additional display 16 is provided for displaying further patient data or other physiological information. Of course, the displays 12, 14, 16 could be integrated into a single display unit that displays many different physiological values ​​and waveforms. Monitor 10 also includes a receptacle 18 configured to receive a plug of a cable connected to the pulse oximetry sensor. The receptacle may have any of a variety of configurations as may be selected by the manufacturer of th...

Abstract

A pulse oximeter sensor (30) includes a sensor plug (32), a cable (34), a light emitting unit (36), and a light receiving unit (38). The light emitting unit includes a first diode (50) and a second diode (52) mounted in an anti-parallel relationship between a first lead (60) and a second lead (62). The light emitting unit further includes a third light emitting diode (54) which is connected back-to-back between the second connector and a third connector (64) in a common anode relationship to the first diode and / or a fourth light emitting diode connected across the second and third leads in an anti-parallel relationship with the third light emitting diode. An adapter cable (20) extends between the sensor plug (32) and a monitor (10) to adapt the sensor plug to a configuration of a socket (18) of the monitor.

Description

[0001] This application claims the benefit of US Provisional Patent Application No. 61 / 335,984, filed January 13, 2010, the disclosure of which is hereby incorporated by reference. technical field [0002] This application relates to the field of medical diagnostics. It is particularly suitable for use in conjunction with a pulse oximetry system and will be described with particular reference to a pulse oximetry system. However, it should be appreciated that the present application may also find particular application in the diagnosis or monitoring of respiratory, blood or other medical conditions. Background technique [0003] Pulse oximeters are commonly used to monitor properties of hemoglobin, in particular to measure oxygen saturation and to monitor pulse rate. Oxygen saturation is usually measured by determining the ratio of the absorbance of two wavelengths of light, usually red and infrared. The relative amount of each wavelength of light absorbed by the blood vari...
