Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
120 words
An oximeter sensor comprising: first and second light sources for illuminating tissue having arterial blood flowing therein, the light produced by each of said first and second sources being at a separate temperature dependent wavelength; temperature indication means for producing an output indicative of the temperature of said first and second light sources; light detection means, responsive to the illumination of said tissue, for producing signals that are proportional to the intensity of the light received at each of said temperature dependent wavelengths; red optical filter means for filtering said light received by said light detection means; and a sensor housing to which said first and second light sources, said temperature detection means, and said light detection means are connected.
Claim 2
Dependent Claim
120 words
An oximeter sensor comprising: first and second light sources for illuminating tissue having arterial blood flowing therein, the light produced by each of said first and second sources being at a separate temperature dependent wavelength; temperature indication means for producing an output indicative of the temperature of said first and second light sources; light detection means, responsive to the illumination of said tissue, for producing signals that are proportional to the intensity of the light received at each of said temperature dependent wavelengths; red optical filter means for filtering said light received by said light detection means; and a sensor housing to which said first and second light sources, said temperature detection means, and said light detection means are connected.
Claim 3
Dependent Claim
236 words
An oximeter sensor comprising: first and second light sources for illuminating tissue having arterial blood flowing therein, the light produced by each of said first and second sources being at a separate temperature dependent wavelength; temperature indication means for producing an output indicative of the temperature of said first and second light sources; light detection means, responsive to the illumination of said tissue, for producing signals that are proportional to the intensity of the light received at each of said temperature dependent wavelengths; a reflective member positioned between said light detection means and said first and second light sources; a sensor housing to which said first and second light sources, said temperature detection means, and said light detection means are connected, wherein said sensor housing comprises first and second elements, said first and second elements being attached to said first element and said light detection means attached to said second element, said first and second elements arranged to allow insertion of said tissue therebetween and to define a light path between said first and second light sources and said light detection means that includes said tissue, said light path including a first segment defined between said first and second light sources and said reflective member and a second segment defined between said reflective member and said light detection means, said first and second segments of said light path being at a predetermined angle to each other.
Claim 4
Dependent Claim
