Distributed pattern for finger nail fold blood capillary
The observation for nail fold micro circulation is mainly from three aspects ,including the shape, the fluid state and the blood vessel ansa perimeter.
Normal state: Nail fold blood capillary arrangement neat, distribution even, the blood vessel ansa is clearly discernible.
Abnormal state: Arrangement disorder, blood vessel ansa fuzzy, is possible to because of the oxygen deficit, the blood stream to be impeded, the Asian health and so on causes.
Blood vessel ansa’s periphery
After has carried on the shape and the fluid state observation, but also should carry on the observation to the periphery condition:
1.Seeps out: refers to, in the blood vessel, appears the phenomenon for the blood plasma ingredient excessively permeability blood pipe wall and the accumulation in blood capillary’s periphery , is one of common micro circulation changes. Characteristic: The blood vessel ansa periphery gap expands, and bright; The blood vessel ansa’s image is fuzzy, the length reduces.
2.Hemorrhage: phenomenon for the red blood cell leaves to the blood vessel outside.
Should distinguish the hemorrhage which the flesh wound or other non- pathogenesis factor creates, if the leakage hemorrhage, the main reason is blood capillary wall damage, causes the permeability hyperfunction and the blood flow changes and so on.
Shape of blood vessel ansa :
(1) Normal shape likes the hair clip , exceptionally for overlapping and abnormal, the overlapping proportion number should not surpass 30%, the abnormal should not surpass 10%.
(2) abnormal blood vessel:
Explained: 1st, the blood vessel of heart and brain disease, the diabetes, the desmosis and so on, with contract whole body disease or the partial fungus infection and flesh wound and other organization disease is easy to appear the blood vessel to be abnormal
2nd, when arteriosclerosis, diabetes with serious abnormal , and the proportion excessive highly.
3rd, collagen disease, Reynold sickness, neurosis, the variation of blood vessel increases.
1) Check the room temperature and humidity. Room temperature and humidity
should be kept relatively constant. room temperature should be maintained in the 22-24 degree , relative humidity about 70%
2) the patient generally take seats, keep the height of the hand the same with heart
3) Preparation of paraffin oil or cedar oil.Drop 2 drops in the nailfold skin. (Purpose prove light
transmission, and reduce skin scattering)
4)Testing generally be in the morning or afternoon, and review should at the same time every day.
5) the patient should
a.Avoiding intense activity or manual labor within one hour before testing
b. Take a rest about 15-30 minutes before testing
c.Can not take any drug which will affect the cardiovascular vessels before testing
d. Does not smoke , wash hands or eat within an hour before testing
e.Pay attention to the influence of the Female menstrual
