Gas measurement module for use in therapeutic settings comprising reflective scanning microspectrometer
Gas within a ventilation circuit is analyzed by a spectrometer included in an airway adaptor that is inserted into the ventilation circuit. The spectrometer is formed from reflective members that process electromagnetic radiation while folding the path of the electromagnetic radiation in such a manner that the form factor of the airway adaptor is enhanced. Further, because of the scale of the spectrometer within the airway adaptor, the cost savings associated with manufacture of the reflective elements instead of refractive elements may significantly reduce the cost of the airway adaptor. |

Medical image recording/playback device
A medical image recording/playback device includes an image pickup device. In an image pickup device that generates an image pickup signal by photoelectrically converting light reflected from a subject through an image pickup element, an image pickup control unit displays, on a display unit, image data that is generated for each of frames that constitute a video by processing the image pickup signal, and records the image data on a memory card. When the video is played, an image shift detection unit sequentially compares image data between consecutive or adjacent frames read from the memory card, and detects an amount of positional shift of a main subject between the frames. If the amount of positional shift is greater than or equal to a preset threshold value, displaying of the image data read from the memory card is stopped. |
