Product Description

Blood taking needle use  in medical test process for collection of blood samples for blood collection needles and is composed of a needle head and a needle bar, needles in the head part of the needle bar, in the needle bar is glidingly connected with a sheath, between the sheath and the needle bar with reset spring and the initial position of the sheath in the needle head and the needle rod head. When the operators hold needle puncture needle head pressing on the limb of a patient, sheath is indented under the action of the elastic force of the skin, needle protruding and stabbed into the skin caused by minimally invasive, when the removal of blood after the needle sheath in under the action of the reset spring to reset the needle covering to avoid needle exposed by contamination or accidental puncture the human body. In the removal of needles, needle and skin cavity surrounded by gradually increasing, the formation of instantaneous negative pressure for blood sampling.

The vacuum blood collecting device is composed of three parts, including a vacuum collecting blood vessel, a blood collecting needle (including a straight needle and a scalp needle) and a needle holder. Blood vessel is the main component of the vacuum, it is mainly used for blood specimen collection and preservation. Mining vacuum vessel in the production process of preset a certain amount of negative pressure, when the blood sampling needle was inserted into the blood vessels, due to the adoption of negative pressure within the blood vessels, blood flow automatically into the mining intravascular; at the same time, intravascular preset the various additives, fully able to meet the clinical multiple blood tests, vaccum hemostix as clinical blood fast and accurate acquisition, with safety, closed, convenient transport, head of a different color, easy to distinguish advantages is revolutionary to the traditional way of blood sampling syringe.

Classification
 

Green head tube
Tube containing lithium heparin and liver [1] is a polysaccharides containing sulfate groups stick with a strong negative charge, can strengthen antithrombin III inactivated the role of serine protease, to prevent thrombin formation, and inhibits platelet aggregation, and other anticoagulant effect. Heparin tube is generally used for the detection of biochemical and blood rheology, and it is the best choice for the detection of electrolytes. Because heparin can cause aggregation of white blood cells, it can not be used for white blood cell count and classification.

Red head tube
Pipe wall are evenly coated to prevent the hanging wall of the silica, while adding a coagulant, coagulant to protease activated fiber, soluble fibrin into soluble fibrin monomer, thus forming a stable fibrin clot. Generally used for hepatitis B virus, thyroid function, drug testing, HIV testing, tumor markers, such as serum immune detection.

Purple head tube
Tubes containing ethylenediaminetetraacetic acid and its salt (EDTA), it is a multi amino carboxylic acid can effectively chelate blood calcium chelating will remove calcium from the reaction, and prevent and termination of endogenous or exogenous coagulation process, thereby preventing blood coagulation, compared with other anticoagulants, comparison, the of blood cell agglutination and blood cell morphology was less affected, so commonly used (2k, 3k, 2Na) salt of EDTA as an anticoagulant. Used for blood cell count and classification, such as general hematology examination, can not be used for blood coagulation, trace elements and PCR examination.

Blue head tube
Tubes containing sodium citrate, sodium citrate by in blood calcium chelation and anticoagulant effect, recommended by national clinical laboratory Committee for Standardization (NCCLS) 3.2% and 3.8%, anticoagulants and blood ratio 1:9, mainly for fibrinolytic system (prothrombin time, thrombin time, activation partial thromboplastin time, fibrin original) detection. Please note that the foot blood blood recovery, prevent the accuracy of the examination result in the death chamber. After blood collection, please immediately reverse mixing 5-8 times.

Black tube
Tubes containing sodium citrate, sodium citrate concentration was 3.2% (0.109mol/L) and 3.8%, the anticoagulant and the blood volume ratio of 1:4, general due to the erythrocyte sedimentation rate, when the anticoagulant ratio is too high, the blood was diluted, the erythrocyte sedimentation rate (ESR).
