Patent Images
1. A pulse oximetry sensor comprising a photoemitter;
- a photodetector; and
, a generally tubular housing having an inner wall, an outer wall and a lumen for receiving a body part of a patient;
said housing having a pair of opposed pockets formed between the inner wall and the outer wall for removably receiving the photoemitter and the photodetector, respectively, said pockets each having a window in the inner wall through which light can pass and an aperture in the outer wall which aperture receives a portion of a respective one of the photoemitter and the photodetector;
said housing also having side passages between the inner wall and the outer wall with each passage having an opening in the housing through which the photoemitter and the photodetector can be introduced into and removed from their respective pockets.

Abstract
A pulse oximetry sensor comprises a photoemitter; a photodetector; and, a generally tubular housing having an inner wall, an outer wall and a lumen for receiving a body part of a patient. The housing has a pair of opposed pockets for removably receiving the photoemitter and the photodetector, respectively. Each of the pockets has a bottom window through which light can pass and an open top. The housing also has side passages between the inner wall and the outer wall of the housing through which the photoemitter and the photodetector can be introduced into and removed from their respective pockets.

- 6. A housing for a pulse oximetry sensor, said housing being a tubular body having an inner wall, an outer wall and a lumen for receiving a body part of a patient, said housing having a pair of opposed pockets for removably receiving a photoemitter and a photodetector, respectively, each of said pockets having a window in the inner wall through which light can pass and an aperture in the outer wall which aperture receives a portion of a respective one of the photoemitter and the photodetector, said housing also having passages between the inner wall and the outer wall with each passage having an opening in the housing through which a photoemitter and a photodetector can be introduced into and removed from the pockets.
- 12. A generally tubular housing for a pulse oximeter sensor, said housing having an inner wall with a pair of opposed windows and an outer wall with a pair of apertures aligned with said windows so that a pair of opposed pockets for receiving a photoemitter and a photodetector are formed with each pocket having a window at the bottom and an aperture at the top, said inner and outer walls being spaced apart to form side passages with an opening in the housing through which either the photoemitter or the photodetector can be introduced into one or both of said pockets.
-
15. A housing for a pulse oximeter sensor, said housing formed by a strip of material coiled in a spiral to form an inner wall, an outer wall and a lumen, with a pair of opposed pockets being formed between the inner and outer walls for receiving a photoemitter and a photodetector, respectively, each pocket having a window that extends through the inner wall;
- the inner and outer walls are spaced apart to form passages through which one of the photoemitter and the photodetector can be introduced into each of the pockets.
