Background technique

Chinese medicine pulse includes biological information abundant, is the important content of the Chinese medicine four methods of diagnosis.Pulsation should refer to the image of (finger) Referred to as pulse condition refers to the image and dynamic of pulse.The formation of pulse condition and internal organs qi and blood are closely related.Shanxi uncle Wang and Pulse Classic are by arteries and veins As being summarized as 24 kinds；Bright Li Shizhen (1518-1593 A.D.) " being on the point of lake pulse study " is set to 27 arteries and veins；Ming Lishi material " examining house to look straight " increase again into Swift pulse closes 28 kinds of pulse conditions.Later age continues to use twenty-eight kinds of pulse condition more.

Pulse condition element refers to four aspects such as element of pulse condition, including position, number, shape, gesture.Artificial pulse condition Identification relies primarily on the feeling of finger.There are many type of pulse condition, and four TCM Document Chang Congwei, number, shape, gesture aspects are analyzed Conclude, the frequency of it and pulse, the rhythm and pace of moving things, the position of presentation, length, width, the fullness degree of vascular, tensity, blood flow it is unobstructed Fluency, the factors such as power of heartbeat are related.Pulse condition element is grasped, for understanding the feature of various pulse conditions and forming machine Reason, can play hold letter drive numerous effect.

One arteries and veins position: refer to the position and length that beat pulse shows.Every time feel the pulse should all examine pulse show position the depth, Length.The position of normal pulse is not floating not to sink, in take and can obtain, cun,guan,chi three have arteries and veins.If table shallow person in arteries and veins position is surface pulse which can be felt when touched only lightly；Arteries and veins position Deep person is eddp pulse etc.；Pulse is more than that three persons of cun,guan,chi are long pulse, and pulsing not as good as very little, ruler person is short arteries and veins.

Two rapid pulses: refer to the extremely several and rhythm and pace of moving things of beat pulse.It feels the pulse the frequency speed that should all examine pulse every time and the rhythm and pace of moving things is It is no uniform.Normal adult, the frequency of pulse is about 70-90 times per minute, and the rhythm and pace of moving things is uniform, is not had a rest only.As respiration five to Upper is rapid pulse etc.；The most retarded pulse of respiration discontented four；Appearance is had a rest only, there is the difference of the arteries and veins such as abrupt pulse, nodus, slow；Arteries and veins restrains speed Irregular person is 35 uncomfortable, there is scattered arteries and veins, weak thready etc..

Three arteries and veins shapes: refer to the forms such as the width of beat pulse.The shapes such as the size of pulse, soft or hard should all be examined by feeling the pulse every time. Arteries and veins shape is mainly related with the factors such as the amplitude of the fullness degree of vascular, pulse wave.If vascular is relatively full, pulse magnitude the greater is Full pulse；Vascular fullness degree is smaller, and pulsatile range smaller is thready pulse；Vascular poor flexibility owes soft person as taut pulse；Arteries and veins body softness nothing Power person is soft pulse, slow arteries and veins etc..
