1. An improved device for collecting a blood sample from a human patient comprising:
- a) an outer shell;
b) an incision means for creating an incision in the patient and mounted in the outer shell wherein the incision is created by controlled longitudinal movement of the incision means in a compartment in the outer shell and a force provided by the incision means to create an incision is independent of any force applied by an operator to the patient;
c) an activation means for activating the incision means in response to pressure being applied against the patient'"'"'s skin wherein the activation means is mounted in the compartment in the outer shell, connected to the incision means and the compartment, and activates the incision means by longitudinal movement in the compartment in response to the pressure being applied against the patient'"'"'s skin; and
d) a collection means for collecting the blood sample from the patient wherein the collection means is slidingly received longitudinally in an open port in the outer shell and is fluidly connected through the incision means to the incision in the patient created by the incision means after the incision means is activated by the activation means.

5. An improved method for collecting a blood sample from a human patient comprising the following steps:
-
a) selecting and preparing a blood acquisition site on the patient for acquiring the blood sample; b) placing a blood sample collection device in contact with the site; c) sliding a tube at a lower pressure than the ambient for collecting blood partially into an open port of the blood sample collection device; d) pressing the blood sample collection device onto the blood acquisition site and thereby activating an activation mean for activating a means for creating an incision in the patient; e) sliding the tube for collecting blood further into the blood sample collection device and into contact with the means for creating an incision in the patient; f) collecting the blood sample in the tube for collecting blood; and g) removing the tube for collecting blood from the blood sample collection device.
