check this tutorial :- http://blog.roychowdhury.org/2010/11/19/cocos2d-iphone-tutorial-die-grossini-die-part-i/ they create blood particle effect manually

Take a look at MotionStreakTest example coming with cocos2d. I Think you can create your own effect based on this.

Or take a look at particle effects. Create a blood emitter and move it with your finger
