Abstract:
An infrared radiation thermometer comprising:(a) a probe head adapted to be introduced into a body cavity wherein said probe head comprises an inner tubular member having a proximal portion fixed within a chamber of a housing such that a distal portion of said inner tubular member extends out of said chamber, said probe head further comprising an intermediate tubular member in coaxial relation around said distal portion of said inner tubular member to provide for telescopic sliding of said intermediate tubular member relative to said inner tubular member, said inner and intermediate tubular members each having a cross-sectional area which is generally uniform longitudinally, said probe head having a slide control mounted within said housing in connection with the proximal end of said intermediate tubular member to provide controllable longitudinal displacement of said intermediate tubular member from a position where the distal end of said intermediate tubular member longitudinally coincides with the distal end of said inner tubular member and a position where the distal end of said intermediate tubular member is positioned longitudinally between said housing and the distal end of said inner tubular member; and (b) an infrared sensor connected to said probe head.
