Claim 16:
17. A method comprising:
coupling a blood collection module to a collection site in skin of a subject;
coupling a transfer module to an angled transfer port of the blood collection module such that an outer wall of the transfer module is angled away from the skin of the subject at an acute angle of between 10 and 45 degrees relative to a sealing surface at a bottom surface of a base of the blood collection module that seals the base to the skin of the subject around the collection site;
sliding a slide latch of the blood collection module with a mechanically selected timing of lancet firing relative to vacuum generation based on relative positioning of blocking elements on a bottom portion of the slide latch in a distal direction towards the angled transfer port to perform:
triggering a momentary lancet strip puncture and retraction at the collection site to produce two rows of 3 to 6 blood extraction slits per row at the collection site to guide blood to flow along the two rows of blood extraction slits, wherein distal ends of the two rows of blood extraction slits are closer together than proximal ends of the two rows of blood extraction slits; and
triggering, with timing relative to the momentary lancet strip puncture and retraction based on the relative positioning of the blocking elements of the slide latch, a distribution of reduced air pressure to facilitate extraction of the blood and components therein from the collection site; and
transferring the blood and components therein from an opening of the blood collection module to the transfer module coupled to the angled transfer port.
