摘要:
The present invention provides a cold reflex tester, in which an electrical device capable of controlling the temperature and maintaining a fixed temperature at a low level based on an electrical signal from a controller is used in a cold stimulator that is brought into contact with a subject's body as a means for applying a cold stimulus to the subject's body. Thus, it is possible to apply a more constant stimulus to a subject's body during measurement and thus improve the reliability of the measurement.The cold reflex tester of the present invention may include a cold stimulator for applying a cold stimulus to the subject's body being in contact with the cold stimulator by maintaining a fixed low temperature based on an electrical signal applied from a controller, a blood flowmeter for measuring blood flow velocity of the subject to detect the body's reaction against the cold stimulus; the controller for controlling the entire system including the cold stimulator and the blood flowmeter and obtaining a measurement result from the blood flowmeter; and a display for displaying the measurement result received from the controller on a screen.
