PHYSIOLOGICAL SENSOR HAVING A WAIST
First Claim
1. A sensor comprising:
- a sensor pad having a first portion and a second portion separated by a waist portion, wherein the waist portion is narrower than the first portion and the second portion;
a light source configured to generate near-infrared light and transmit the near-infrared light through part of a patient'"'"'s body; and
a light detector configured to detect near-infrared light that has traveled through the part of the patient'"'"'s body, wherein the near-infrared light detected indicates an amount of oxygen in the part of the patient'"'"'s body through which the near-infrared light traveled.

Abstract
An exemplary sensor includes a sensor pad having a first portion and a second portion separated by a waist portion. The waist portion is narrower than the first portion and the second portion. A light source that is disposed on the first portion is configured to generate near-infrared light and transmit the near-infrared light through part of a patient'"'"'s body. A light detector that is disposed on the second portion is configured to detect near-infrared light that has traveled through the part of the patient'"'"'s body. The near-infrared light detected indicates an amount of oxygen in the part of the patient'"'"'s body through which the near-infrared light traveled.

11. A sensor pad comprising:
-
a first portion configured to house a light source that generates near-infrared light and transmits the near-infrared light through a part of a patient'"'"'s body; a second portion configured to house a light detector that detects near-infrared light after the near-infrared light has traveled through a part of the patient'"'"'s body, wherein the light received indicates oxygen saturation of the part of the patient'"'"'s body through which the light traveled; and a waist portion disposed between the first portion and the second portion, wherein the waist portion is narrower than the first portion and the second portion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A sensor comprising:
-
a sensor pad having a first portion and a second portion separated by a waist portion, wherein the waist portion is narrower than the first portion and the second portion, the second portion including a light blocking material and the waist portion including a flexible material; a light source disposed on the first portion and configured to generate near-infrared light and transmit the near-infrared light through a part of a patient'"'"'s body; a light detector disposed on the second portion and configured to detect near-infrared light that has traveled through part of the patient'"'"'s body to identify an amount of oxygen in the part of the patient'"'"'s body through which the near-infrared light traveled, and wherein the second portion substantially prevents the light detector from receiving interfering light; an adhesive disposed on the sensor pad; and a liner disposed on the adhesive and defining a slit located near or over the waist portion. - View Dependent Claims (20, 21)
