The vacuum adopts a blood machine to be adopted blood vessel by the vacuum Blood Collection Tubes, adopt blood needle(include to keep needle and skin of head type to adopt blood needle) and hold a needle machine three parts constitute.The vacuum adopts blood vessel is that it mainly constitutes part and mainly useds for collecting of blood specimen and keeps.The vacuum adopted blood vessel to prepare to place one fixed amount in the production line of negative the needle press, being to adopt blood wear a sting after getting into the blood vessel in order to adopting inside the blood vessel of negative press a function, blood automatically inflow adopt inside the blood vessel;In the meantime, adopted to prepare to place various additive inside the blood vessel, completely can satisfy many clinical blood examinations with comprehensive item, the vacuum adopts blood machine as clinical blood quickly accurate collect, have safety, closeness, transport convenience, head the color is different and be easy to distinguish etc. advantage, is to tradition of inject the revolution that the machine adopts a blood method innovation.
Pressing the cranium coloring is different, my hospital uses currently of the vacuum adopt blood vessel to is divided into following 8 kindses:
1, The green head take care of:The tube contains heparin lithium, the heparin is a kind of function that implies gluing of sulfuric acid radicle regiment much sugar and takes to has strong negative charge, have to strengthen the anti- Ning blood Mao Ⅲ to put out to live the silk ammonia sour egg white Mao and obstruct Ning blood thus the formation of the Mao, also the arrestment blood platelets gathering wait various anti- Nings function.The heparin tube generally useds for the examination that bio-chemical and blood change, is the best choice of electrolyte examination.Because the heparin will cause white cell gathering, past can not used for white cell to count and categorize.
2, The red head take care of:Wall inside the tube even Tu You prevent°froes hanging wall of two oxidize Huo, added to urge a Ning in the meantime, urging the Ning could activate fiber egg white Mao and make dissolubility fiber the egg white become the fiber egg white of dissolubility not to gather a body and then form a stable fiber egg white Ning piece.Generally used for hepatitis virus, thyroid gland function and medicine examination and moxa Zi disease examination and tumor sign thing etc. serum immunology examination.
3, The purple head take care of:The tube contains B two Ans are four acetic acid and its salt(EDTA-), it is that many a kind of ammonia radicle Zui radicles are sour, can availably the Ao matches the calcium ion in the blood, the Ao matches a meeting calcium from respond to order to move to walk, and obstruct and terminate inside source or the outside source Ning blood process, prevent°from blood concretion thus, with other anti- Ning comparison but speech, it to blood cell of solidify and the appearance of blood cell contain smaller influence, so usually use EDTA salt(2 Ks, 3 Ks and 2 Nas) as anti- Ning.Used for blood cell to count and categorize to wait a general hematology check, can not used for Ning blood, trace element and PCR check.
4, The blue head take care of:The tube contains the Gou Yuan sour sodium, the Gou Yuan sour sodium is passed to the calcium ion in the blood kind, the Ao matches but has the anti- Ning the function, the national clinical studies room standardizes committee(NCCLS) to recommend to 3.2% or 3.8%, anti- Ning and blood comparison is 1:9, mainly used for the examination that the Xian dissolves system(Ning blood Mao original time, Ning blood Mao time, activate parts of Ning blood Mao time, the fiber egg white is original).Please watch for to adopt enough accuracy that blood quantity eradicate completely to die inside the tube a chamber influence examination result while adopting blood.Please immediately reverse to mix to divide 5-8 times after adopting blood.
5, The black head take care of:The tube contains the Gou Yuan sour sodium, the density of the Gou Yuan sour sodium is 3.2%(0.109 mols/L) and 3.8%, it anti- Ning and blood of the physical volume compare to 1:4, general because the blood sinks an examination, when anti- Ning comparison is too higher, blood drive dilution, can make the blood sunk to speed.
