1. A lancing device comprising:
a lancet connector for connecting with a lancet which comprises a lancet body and a needle fixed to and extending from the lancet body;
a reciprocating actuator operably connected to the lancet connector and configured to cause a linear reciprocating motion of the lancet connector along an axis;
a trigger configured to trigger the reciprocating actuator for causing the linear reciprocating motion of the lancet connector;
a lancing device body comprising a main body portion, a lancet receiving portion and a tip portion that are arranged in order along the axis and integrated to form a single body;
the main body portion being configured for gripping with one hand of a person;
the tip portion comprising a skin contact surface for contacting a skin area from which blood is to be sampled;
the lancet receiving portion interposed between the main body portion and the tip portion therebetween; and
a handle disposed outside the lancing device body such that the handle, the main body portion and the lancet receiving portion are arranged in order along the axis, wherein the reciprocating actuator comprises a spring for storing spring energy,
wherein the handle operably connected to the reciprocating actuator and is configured for pulling away from the main body portion along the axis, which is to store spring energy in the spring of the reciprocating actuator,
wherein the reciprocating actuator comprises a cam configured to rotate about a cam axis and a cam follower operably connected to the cam to move back and forth along the axis, wherein the lancet connector is operably connected to the cam follower for the linear reciprocating motion.
