<P>PROBLEM TO BE SOLVED: To provide a casing for a device for monitoring subject blood flow non-invasively. <P>SOLUTION: This casing includes: a magnetic field generating source 21 for generating a local single directional, constant magnetic field; a signal acquisition module including a magnetic sensor which is arranged in the magnetic field and detects the variation in the magnetic field due to the blood flow; and an attenuation type buffer 23 of a gas type. In this case, the magnetic field generating source 21 is arranged inside or on a surface of the attenuation type buffer 23 of the gas type. Thus, the device is capable of multiplying or propagating the variation in the magnetic field due to the blood as well as being capable of shutting out outside noise regarding the variation in the magnetic field. Furthermore, thus abnormality in the pulse rate and the blood flow can be monitored under suitable measuring conditions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
