The invention belongs to the field of biomedical testing instruments, and mainly relates to a precision pulse testing
system which comprises a
forearm positioning device, three channels of
signal acquiring devices, a power supplying module, a
pressure monitoring and controlling module, a
signal acquiring and converting module, a
signal processing and displaying module and the like. The precision pulse testing
system has the advantages that three-portion and nine-
pulse taking procedures carried out by traditional Chinese physicians can be precisely simulated by the aid of a
manipulator on the basis of a bionic principle; sensors are
graphene capacitive micro-array flexible thin-film sensors, are effectively adaptive to individual tissue structure difference and accordingly can be effectively in contact with tissues of the skins of the
wrist of a patient, 400 channels micro-array signals can be acquired by each sensor in real time, and transversal and longitudinal spatial resolution (of 0.4
millimeter) of the signals can be greatly improved; postures of the
forearm elbow, the
wrist and the palm of the patient can be adjusted and keep in optimal acquisition states by the aid of the precision pulse testing
system, pulses can be simultaneously acquired from the
forearm elbow, the
wrist and the palm of the patient, and the forearm
elbow, the wrist and the palm of the patient can be repeatedly and precisely positioned; by the aid of the precision pulse testing system, 28 pulses of the patient can be precisely judged and taken, a microscopic pulse condition of the patient can be analyzed, and four-dimensional image maps of pulse
waves of the patient, time-domain pseudo-color topographical maps and the like can be outputted.
