How to deal with blood in syringe without losing the oil

[The God Himself]

You can inject it to a different spot without getting rid of the blood at all, its your blood after all.

Hey, cheers Sorry I think I didn't explain well, I meant the blood blocks the needle when it reaches the needle while injecting so I have to be very careful such as when I inject a little bit of oil the blood tries to rush into needle, I can't let it go to the needle because if it goes to the needle it blocks it and plunger doesn't budge. So I push, wait for blood to raise up, push a little again, wait for blood to raise up

Attached the blocked needle

You can try a wider needle may be? Nurses dont draw blood with tiny needles not to damage red blood cells afaik
