Abstract

A blood analyzer capable of obtaining a blood analysis result instantaneously without sampling blood but rather applying a DC current to blood flowing through an artery and irradiating it with an ultrasonic wave is provided. It is equipped with a main measurement unit 110 having a positive electrode and a negative electrode placed apart from each other, ultrasonic wave transmitting/receiving probes, which are sandwiched between the positive electrode and the negative electrode and placed adjacent to the positive electrode and negative electrode, and ultrasonic wave transmitting probes placed sandwiched between the ultrasonic wave transmitting/receiving probes, each of which is protruding from the surface and, provided inside of the main measurement unit 110, a measuring control unit comprising: a DC application unit, a positive electrode and a negative electrode, an ultrasonic wave output unit, an ultrasonic wave reception unit, and a component analysis.

Claims

1. A blood analyzer comprising:

ultrasonic wave transmitting/receiving probes placed above a blood vessel;

ultrasonic wave transmitting probes placed above said blood vessel in order to agitate blood inside said blood vessel;

an ultrasonic wave output unit for emitting an ultrasonic wave from said ultrasonic wave transmitting/receiving probes and said ultrasonic wave transmitting probes;

an ultrasonic wave reception unit for receiving a reflecting wave from said blood via said ultrasonic wave transmitting/receiving probes; and

a component analysis unit for operating said ultrasonic wave output unit and said ultrasonic wave reception unit in order to analyze components of said blood based on the waveform of the reflected wave received by said ultrasonic wave reception unit.

5. The blood analyzer claimed in either one of claims 1 through 3 wherein an unspecified number of said ultrasonic wave transmitting probes are provided.
