Disposable Vacuum Blood Collection TubeUse method:
1. choose venipuncture position with the help of tourniquet
2. disinfect the selected venipuncture position with cotton swab
3. unscrew the blood sampling needle sheath and ensure the arm down
4. push the needle into the veins for blood sampling
5. let go of the toruniquet after blood flows into the blood collection tube
6. press the venipuncture position for five minutes with new cotton swabs to stop bleeding

vacuum blood collection tube use steps and the matters needing attention and matters need attention
1, the vessels of the mining in health and the influence factors of speed picks:
The disposable use BCT collection capacity in the medical personnel operating right circumstances, can follow the altitude of sampling sites, atmospheric pressure, blood sampling needle and inner diameter of venous blood pressure and blood viscosity of different variations. For various types of mining for blood vessels, the blood vessels in health by mining in less than blood vessels faster collection, is normal phenomenon.
2, storage temperature:
Adopt the blood vessels of the storage environment temperature 4-25 ºC. If the storage temperature at 0 ºC or lower than 0 ºC, may cause by the bursting of the blood vessels.
Three, before using the note:
(1) such as blood sampling tube foreign or sediment exist, please do not use;
(2) please do not use more than an expiration of the adopt of blood vessels;
(3) in the blood vessels for the disposable use, after use should be placed in special processing containers, to be destroyed;
(4) medical personnel in the blood collection, blood analysis and blood relay in the process, we should bring gloves protect utensils, prevent blood splashed or revealed on, avoid blood infection.
4, use in blood vessels, keep tube liquid surface below the puncture point, prevent blood flow back.
Because some negative pressure containing blood tube chemical additives, so should prevent blood may adopt of vessels from backflow, cause the patient's reaction. To ensure that the blood does not produce backflow problems, we should pay attention to the following points.
(1) will be mining people arm down placed;
(2) will adopt blood vessels with one end of the helmet, keep in the position of the upward;
(3) in the venipuncture, ensure additive is not with stopper and picks one end of the needle contact.
BCT use steps and the matters needing attention, use the blood vessels of the mining operation steps
1, according to the testing purpose, choose the size of mining vessels;
2, will double top picks loaded to on the support needle (see "double needle picks the instruction for use") and to ensure that the double needle breaket collection firm;
3, will be sampling people arm down placed, choose venipuncture position, the application of a tourniquet, and with the right method of disinfection disinfection of lumbar puncture position;
4, unscrew the blood sampling needle sheath, and ensuring the arm down and picked up one end blood vessels safety helmet of lumbar puncture;
5, will push the stents in blood vessels, that picks the other end of the needle through the stopper. In the piercing stopper should guarantee the collection tube is located in support of the hole middle position, prevent side wear, avoid negative pressure of premature lost.
6, blood once in mining blood vessels that let go of a tourniquet, if not in health or no blood flow in blood vessels, it is advisable to take the following steps in order to obtain satisfactory results:
(1) will be pushed forward in blood vessels, and make sure that the stopper is through;
(2) adjustment in the position of the intravenous needle;
(3) change a branch in new blood vessels push the stents set of tube;
(4) if the change in blood vessels can't picks, removed and a discarded needle two-headed picks. Repeat step 1 start from the operation.
7 and when mining blood vessels in the collected blood to the expected amount and blood vessels in inflows to stop when will adopt blood vessels from out of stent;
8, when from a collection of multiple blood samples collected objects, repeated operation step 5-7;
9, will the blood vessels of the collection in turn up and down six times, then will adopt one end of the safety helmet with blood vessels made up is placed.
10, when complete after sampling, will double top picks out vein needle. With disinfectant to puncture sign position oppression hemostatic;
11, venipuncture, glue the fort may remain blood, blood vessels in mining operation should be paid attention to when avoid and blood contact. Any blood pollution brace for cleaning decontamination, or the other appropriate treatment;
12, to use a double-headed picks with appropriate instruments needle for processing.
