Can be a large-capacity blood bank dedicated centrifuge L6-6KR can stand the test of practice
With the continuous increase of blood in clinical components, blood separation has become a necessity. At present, blood collection and blood supply institutions prepare whole blood into various components. The blood is mainly separated by high-speed centrifugation. When blood is broken at high speed, blood bag breakage sometimes occurs. To waste valuable blood resources, in order to effectively reduce the blood scrap rate and reduce the loss of blood, special attention will be paid when selecting a centrifuge for blood banks .
It can become a test of the blood bank dedicated high-capacity centrifuge stand the practice of L6-6KR, following brief procedure uses L6-6KR blood bank blood banks in the private blood bank centrifuge. There are pictures with truths~~
material:
1, a number of blood bags
2, can be a large-capacity blood bank dedicated centrifuge L6-6KR one, the centrifuge cup is round, the blood station dedicated horizontal rotor 6 × 1000 / ml, one can separate 400ml five blood bags at a time;
Steps:
The first step: visual inspection of each bag of whole blood to ensure no leakage, each heat sealing mouth is intact.
The second step: weighing and balancing the blood bag.
The third step: the blood is placed in the centrifugal hanging cup, and the catheter is wound and plugged on the side wall during the loading, and the symmetry is hung on the centrifugal bracket after the trimming.
The fourth step: the centrifuge parameter setting: temperature 4 ° C, the speed is 3500r / min, the time is 10min.
Step 5: After centrifugation, take it out and put it in the storage basket, waiting for separation.
Step 6: The centrifuged whole blood bag is gently placed on the pressure plate, the upper layer of plasma is removed to a transfer bag, and the red blood cell preservation solution is added to prepare a red blood cell product.
The whole process is convenient and simple to operate. The blood bag after centrifugation is well-defined, and the blood bag is intact during the whole process, and the centrifugal effect is clear at a glance. It’s really good to see it, so Xiaobian can recommend it to you as a centrifuge~~
Of course, in the process of using the blood bank centrifuge, if the blood bank centrifuge is damaged when it is centrifuged, the user should analyze the cause of the failure, including:
1. Exposed of the catheter: Since the position of the blood bag into the centrifuge cup is insufficient, the catheter and the cover tube are exposed at a high position on the upper end of the centrifuge cup, or the catheter is suspended outside the centrifuge cup, the catheter will have no obstruction. Was pulled out of the centrifuge cup. As a result, the catheter is broken and the Clicktip injures the cover tube. The Hunan Centrifugal Machine reminds you that it is very dangerous to have the catheter wrap around the centrifuge shaft.
2, dead space: "dead cavity" is the biggest cause of centrifugal damage. During the centrifugation process, the blood bag is subjected to a large centrifugal force, and if it is converted into a weight, the weight of one bag is hundreds of kilograms or even more than one ton. If the blood bag is in full contact with the centrifuge cup, the centrifuge cup will fully withstand this tremendous force and will not cause damage to the blood bag. However, if there is a dead space between the blood bag and the centrifuge cup, the sheet having a thickness of about 0.4 mm cannot withstand the force of the blood sucked into the dead space, thereby causing deformation (bumps) and breakage.
3. In addition to the parameters of the centrifuge and the quality of the blood bag itself, the neglect of certain links during the blood separation during operation of the centrifuge is also one of the causes of the centrifugal damage of the blood bag.
Don't doubt the effect of domestic production, everything is in front of you, clean and thorough. The domestic market has always been occupied by imported equipment, and it can be used as a blood bank dedicated centrifuge L6-6KR to enter the blood bank blood bank. We can do better.
