A blood blister that results from a pinch is an accumulation of blood as a result of trauma to the skin.
It is best NOT to pop a blood blister as this can lead to infection and possibly even delay the natural healing process of your body. Covering the blood blister with a soft dressing to keep it protected can be helpful as it resolves on its own.
If the person who has the blood blister has any underlying health conditions, especially diabetes, it would be appropriate to seek medical care.
If the blood blister pops on its own, do not peel off the remaining skin. Rather, leave it in place, treat the area with an antiseptic ointment and cover with a clean dressing. Allow it to heal in its own time.
If the injury is very recent, ice can help to reduce the pain that the trauma initially induced.
