Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A finger probe 10 for positioning on the end of a patient's finger, said finger probe 10 being characterised by an upper housing 20 and a lower housing 22, said upper housing 20 and said lower housing 22 being pivotably connected together at the distal ends 12 thereof, said upper housing 20 and said lower housing 22 thereby forming an internal chamber 26 open at the proximal end 14 for receiving the finger, light detector means 38 affixed to one housing 22, and a light emitter housing 42 pivotably connected to the other housing 20, said light emitter housing 42 having a light emitter 52 adapted to direct light across said internal chamber 26 to be received by said light detector means 38, said-pivotal connection of said light emitter housing 42 allowing movement thereof to conform to the profile of a finger positioned in said internal chamber 26.
Claim 2
Dependent Claim
148 words
A finger probe 10 for positioning on the end of a patient's finger, said finger probe 10 being characterised by an upper housing 20 and a lower housing 22, said upper housing 20 and said lower housing 22 being pivotably connected together at the distal ends 12 thereof, said upper housing 20 and said lower housing 22 thereby forming an internal chamber 26 open at the proximal end 14 for receiving the finger, light detector means 38 affixed to one housing 22, and a light emitter housing 42 pivotably connected to the other housing 20, said light emitter housing 42 having a light emitter 52 adapted to direct light across said internal chamber 26 to be received by said light detector means 38, said-pivotal connection of said light emitter housing 42 allowing movement thereof to conform to the profile of a finger positioned in said internal chamber 26.
Claim 3
Dependent Claim
37 words
A finger probe as claimed in Claim 1, characterised in that the light detector means 38 is affixed to the lower housing 22 whilst the light emitter housing 42 is pivotally connected to the upper housing 20.
Claim 4
Dependent Claim
36 words
A finger probe as claimed in Claim 1 or Claim 2 characterised by spring bias means 32 to bias the proximal ends 14 of said u.pper housing 20 and said lower housing 22 towards each other.
Claim 5
Dependent Claim
39 words
A finger probe as claimed in Claim 2 or Claim 3 characterised in that said lower housing 22 and said light emitter housing 42 each have curved surfaces 34, 48 facing the finger when positioned within said internal chamber.
Claim 6
Dependent Claim
62 words
A finger probe as claimed in anyone of Claims 1 to 4, characterised in that said light detector means 38 and said light emitter 52 include wiring means to wires external of said finger probe, said external wiring comprising wires 16 depending outwardly from said proximal end of said finger probe and generally conforming to the finger positioned within said finger probe.
Claim 7
Dependent Claim
57 words
A finger probe as claimed in Claim 5 characterised in that said external wiring 16 includes a strain relief flap 18 adjacent and depending outwardly from said light emitter housing 42, said strain relief flap 18 being shaped to conform to the finger position within said finger probe and adapted to be readily taped to the finger.
Claim 8
Dependent Claim
56 words
A finger probe as claimed in any one of Claims 2 to 6 characterised in that said pivotable connection between said light emitter housing 42 and said upper housing 20 comprises pegs 44 depending outwardly from said light emitter housing 42 and fitted within recesses 46 formed in the internal surface of said upper housing 20.
