1. A blood collection assembly characterized by(a) a tube-shaped container;
- (b) said container having a closed end and an open end;
(c) a blood collector mounted on said open end;
said collector including(1) a substantially tubular collector body having a tubular flow passage therethrough;
(2) said body extending from a puncture wound engaging front end surface to a blood discharge rear end surface;
(3) means on said body for attaching said body to said open end of said container;
(4) vent means in said body for air displacement therethrough;
(5) said front end surface having a large circumferential extent;
(d) a lancet positioned in said collector with the cutting edge thereof positioned adjacent said front end surface of said collector;
(e) a removable cap connected to said container for mounting on said blood collector for closing the front end thereof and covering said lancet;
(f) two-position cooperating locking means on said blood collector and said cap for removably holding said cap on said collector in a first position and for permanently locking said cap on said collector and lancet in a second position and(g) said two-position cooperating locking means including(1) a first annular abutment on said blood collector body, said first annular abutment extending outwardly from said body;
(2) a second annular abutment on said cap, said second annular abutment extending inwardly from said cap; and
(3) a tapered surface on said second annular abutment for camming said second abutment over said first abutment into said permanent locking second position of said cap on said collector.

Abstract
A blood microcollection container and associated lancet-collection assembly is provided for making a puncture wound, engaging the wound and rapidly receiving blood from the wound. The assembly incorporates a lancet together with a scoop arrangement for engaging the blood source, and for directing in a rapid and efficient manner the blood to a collection chamber. A two-position cap is provided for sealing the scoop collector of the assembly prior to use, and for permanently locking to the collector after use to prevent exposure of the lancet and collector to the person handling the blood sample, or contamination of the blood sample from outside sources.
