One. Function and use
This model uses bionic simulation and waveform synthesis methods to produce more than 12 common TCM pulses on the wrist (in the mouth) of the model made of polymer materials. These pulses are typical of the eight-class pulse of traditional Chinese medicine and are the basis of clinical syndrome differentiation. Familiar with these basic pulses can be used in practice, and gradually master the method of pulse diagnosis. This model, as a signal source for pulse recurrence of traditional Chinese medicine, can be used in the teaching process of pulse diagnosis, creating good practice opportunities for repeated training for students. It is an ideal teaching tool and can also be used for in vitro experimental research on the mechanism of pulse formation.
The appearance of the pulse model confirms that the parameters of the existing pulse map can express the basic mechanical characteristics of various pulse types, so the pulse map analysis method can replace the finger to cut the pulse, realize the visualization and quantitative analysis of the pulse, and it is more reliable than the cut pulse. And advanced.
The whole model of this model has passed the safety performance inspection of the National Medical Device Quality Supervision and Inspection Center [National Medical Inspection (Set) word QW95 No. 107] in compliance with national standards. The polymer model hand and latex tube used in this instrument have been tested by Shanghai Plastics Research Institute and the working aging time has reached more than five years. [Outside the number 95-181].
two. System composition and block diagram A complete set of pulse model consists of four (A, B, C, D) split models.
Group A models: output flat, slip, late, and pulse.
Group B models: output flood, leather, float, and number veins.
Group C model: output string, knot, generation, and pulse.
Group D model: output heavy, thin, astringent, weak pulse.
Brief system block diagram:
1 Single-chip computer: EPROM stores a variety of data to control the operation of the hydraulic system.
2 Hydraulic system: It is a low-pressure, small-flow hydraulic system that simulates the arterial flow of the human body. Using wave pattern synthesis methods, more than 12 pulsating pressure waves are generated in the piping system.
3 Bionic model hand: Bionic model made according to real anatomical characteristics and position. More than twelve kinds of pulsations occur in the radial artery.
three. Use environment model Normal use environment: the temperature is normal temperature (preferably not higher than 28 ℃), and the air pressure is under standard conditions.
