Description

A kind of pulse-taking instrument with voltage-limiting protection function

Technical field

The present invention relates to a kind of pulse-taking instrument with voltage-limiting protection function.

Background technology

At present, pulse-taking is by the pulse by tactile human body different parts, to observe and learn the palpation method of pulse condition change by experience.Also known as feeling the pulse, feel the pulse, feel the pulse, feelling pulse.Formation and the internal organs QI and blood of pulse condition are closely related, if internal organs QI and blood generation pathological changes, blood vessels run and will be affected, and pulse condition just changes.Pulse-taking clinically, the advance and retreat prognosis of deducibility disease.The pulse-taking that Ancient Times in China medical science adopts in diagnosing the illness is a unique diagnostic method arteries and veins, is one of traditional Chinese medical science " four diagnostic methods " (hope, hear, ask, cut), is also a kind of indispensable objective basis of determination for the treatment of based on pathogenesis obtained through differentiation of symptoms and signs.

In recent years, due to doctor trained in Western medicine at home prevailing, in addition the traditional Chinese medical science is overly dependent upon old docter of TCM doctor traditionally, make that the traditional Chinese medical science is once once out in the cold is even ostracised, and along with the effort of China's medical science and researcher, also started in recent years to be developed and progress, after particularly Chinese medicine being combined with modern diagnosis thinking, the traditional Chinese medical science starts again to obtain tremendous development theoretically with on diagnostic method.

In clinical practice, when doctor feels the pulse for patient, beating of pulse can stimulate Wagner's corpuscles, power conversion is carried out by Wagner's corpuscles, physical stimulation is converted to electroneurographic signal, be transferred to nerve centre brain via sensory nerve and form sense of touch, then form various pulse condition in conjunction with relevant medical knowledge.Because the formation of sense of touch is a kind of subjective feeling in this process, therefore to all there is a lot of subjective content in the description of pulse condition.Therefore, Traditional Chinese Medicine pulse-taking is all indivisible with the sensory perception of doctor, and this just causes evaluation to state of an illness neither one objective criterion and definition, greatly limit popularization and the accreditation of pulse wave spectrum.

Existing commercially available pulse-taking instrument adopts stepper motor driven rigidity Self-pressurizing agri to design, control signal is sent by PC control system, can the step distance of accurate control step motor by drive circuit, use between step motor drive parts and probe and be rigidly connected, thus realize the accurate location of popping one's head in pressure process, evaluation and the definition of an objective criterion can be done to a certain extent to the state of an illness, but there is certain risk out of control in frame for movement, although can pass through computer installation safe spacing program, it is perfectly safe also can not to accomplish.And pulse-taking instrument is the most dangerous and easily out of control be exactly stepper motor driven rigidity Self-pressurizing agri, probe directly contacts with the wrist of people, owing to being positive drive structure, so once out of control, will cause very large injury to wrist.

Summary of the invention

For solving above technical deficiency, the invention provides a kind of pulse-taking instrument with voltage-limiting protection function, it is reasonable in design, and protected effect is good.

The present invention is achieved by the following measures:

A kind of pulse-taking instrument with voltage-limiting protection function of the present invention, comprises frame, in described frame
