Tim Peake: how to draw blood in space


ESA astronaut Tim Peake shows how to draw blood for research on the International Space Station. Researchers often request samples before, during and after a spaceflight to examine differences.

The tubes of blood are put in a refrigerated centrifuge and then stored in the International Space Station’s –80°C freezer called MELFI for later analysis on Earth.

  1. I curious how do organs work in space and even food go down the body. Pressure just shove the food down? And pressure shove it through the gastrointestinal tract? Also the bloody flow around the body.

  2. Very tricky to keep the needle sterile with that vacutainer hub drifting around close to it. And interesting to see how he could put immediate pressure on the venepuncture site post draw. Solution: he couldn't until he put the needle down. Probably a lot safer for a person to do his own stick in these conditions than have a buddy doing it!
