How do you do it? I did it myself twice but honestly I don't have a comfortable chair or seating. That is the biggest problem, and then you gotta take the tubing to the needle and into a bottle or something. Too much of a hassle for me. Interested to hear your set up.
Some guys make a mess in the shower.
Link to thread here where I wrote some stuff and copy below from another forum.
Self phlebotomy
A. 5/32" OD polyurethane tubing, preferably clear.
B. 18 gauge x 1.5" needle
C. BP cuff
D. 16 oz clear water bottle
E. first aid tape (I use electric tape)
F. gauze wrap
1. cut polyurethane tubing to about 4 feet long.
2. insert one end of tubing into the needle luer lock opening (should press fit), then wrap with tape to insure tubing stays in.
3. poke two small holes in the water bottle cap, make sure they are smaller than the tubing so the tube press fits in. (I just tape tubing into bottle and do it sitting on edge of bathtub so if it spills....contained and cleanable)
4. press the other end of the tube into one of the holes and secure with tape if needed, and leave the other hole open.
5. put the cuff on but do not pump.
6. find the vein and clean the are with alcohol few times.
7. get a large cotton ball ready for after pulling the needle out.
8. pump the cuff until you can feel the vein then with a quick move stick the needle in at a very shallow angle. remember the vein is only skin deep, so make sure you go in with very shallow angle. you should see blood shoot though the tubing and into the bottle. if blood slows down simply squeeze your fist every few seconds, if still slow you can increase the cuff pressure as needed.
IMPORTANT!
when pulling out the needle make sure the cuff is completely deflated, otherwise you'll bleed allover the place
9. when finished deflate the cuff completely and pull the needle out, then immediately place a large cotton ball on the area and press firmly, rise your hand for about a minute or so then check and see if the bleeding stopped. add a new cotton ball then wrap with gauze for about 3 hours or so. this part is much easier if someone else does it for you.
