Abstract
An in vivo device and a method for collecting and measuring oximetry data in a body lumen, such as using a swallowable capsule. The in vivo device may include instruments for collecting oximetry data, for example an illuminator and an oximetry data detector.
Claims18
An autonomous in-vivo device comprising a unit to measure oxygenation of hemoglobin in a blood stream, said device when inside a body not including any physical connection to an additional device, the unit comprising:
- at least two cavities limiting backscatter or sidescatter light access, wherein a first of said at least two cavities includes either an illumination source or a detector recessed therein and a second of said at least two cavities includes the other of said illumination source or said detector recessed therein,
- said unit arranged such that light emitted by the illumination source is detectable by the detector when said device is inside a body.
A system for measuring the oxygenation of hemoglobin in a blood stream, the system comprising:
- an autonomous in vivo device that, when inside a body does not include any physical connection to an additional device, comprising
- an instrument to collect oximetry data;
- at least two cavities limiting backscatter or sidescatter light access, wherein a first of said at least two cavities includes either an illumination source or a detector recessed therein and a second of said at least two cavities includes the other of said illumination source or said detector recessed therein,
- said unit arranged such that light emitted by the illumination source is detectable by the detector when said device is inside a body;
- and
- an external receiving unit to receive transmitted information.
A method of in vivo measuring of oximetry, the method comprising:
- inserting an autonomous in vivo device into a body lumen, said device when inside the body lumen not including any physical connection to an additional device;
- illuminating tissue of said body lumen with an illuminator in the device, the illuminator recessed in a cavity limiting backscatter or sidescatter light access;
- detecting light diffused from a tissue of said body lumen by a detector in the device, the detector recessed in a cavity limiting backscatter or sidescatter light access;
- and
- calculating oximetric readings based on the detected diffused light.
