Abstract
This disclosure relates to a system and method for drawing blood from a user by skin puncture instead of venous puncture and storing it for analysis. The system includes a receptacle configured to engage an area of skin of the user at a blood draw location and store blood drawn from the user; a lancet device disposed within the receptacle configured to puncture the skin of the user at the blood draw location; a vacuum device configured to reduce a pressure within the receptacle such that the skin at the blood draw location is drawn into the receptacle before the lancet device punctures the skin, and to enhance blood flow while blood is drawn from the user; and a housing configured to house the receptacle, the lancet device, and the vacuum device. The receptacle, the lancet device, and the vacuum device may be modular and removably coupled with the housing.
