Abstract
Abstract A blood microcollection container and associated collection assembly is provided for engaging a puncture wound and rapidly receiving blood from the wound. The assembly incorporates 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 to the blood sample by the person handling the blood sample, or contamination of the blood sample from outside sources.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
172 words
A blood collection assembly with (a) a tube-shaped container (12) particularly microcollection container; (b) said container (12) having a closed end (16) and an open end (14); characterized by (c) a blood collector (32) mounted on said open end (14); said collector including (1) a substantially tubular collector body (18) having a tubular flow passage (22) therethrough; (2) said body (18) extending from a puncture wound engaging front end surface (62) to a blood discharge rear end surface (34); (3) means on said body (18) for attaching said body to said open end (14) of said container (12); (4) said front end surface (62) being tapered and having a large circumferential extent; (d) a removable cap (20) mounted on said blood collector (32) for closing the front end thereof; (e) two-position cooperating locking means on said blood collector (32) and said cap (20) for removably holding said cap (20) on said collector (32) in a first position and for permanently locking said cap (20) on said collector (32) in a second position.
Claim 2
Dependent Claim
172 words
A blood collection assembly with (a) a tube-shaped container (12) particularly microcollection container; (b) said container (12) having a closed end (16) and an open end (14); characterized by (c) a blood collector (32) mounted on said open end (14); said collector including (1) a substantially tubular collector body (18) having a tubular flow passage (22) therethrough; (2) said body (18) extending from a puncture wound engaging front end surface (62) to a blood discharge rear end surface (34); (3) means on said body (18) for attaching said body to said open end (14) of said container (12); (4) said front end surface (62) being tapered and having a large circumferential extent; (d) a removable cap (20) mounted on said blood collector (32) for closing the front end thereof; (e) two-position cooperating locking means on said blood collector (32) and said cap (20) for removably holding said cap (20) on said collector (32) in a first position and for permanently locking said cap (20) on said collector (32) in a second position.
Claim 3
Dependent Claim
47 words
The assembly of Claim 1, further characterized by (a) a vane (30) positioned in said tubular flow passage (22), said vane (30) dividing said tubular flow passage (22) into a blood flow passage (35) and a vent means (24) in said body (18) for air displacement therethrough.
Claim 4
Dependent Claim
97 words
The assembly of Claim 1 or 2, further characterized by said two-position cooperating locking means including (a) a first annular abutment (48) on said blood collector body (18), said first annular abutment (48) extending outwardly from said body (18); (b) a second annular abutment (46) on said cap (20), said second annular abutment (46) extending inwardly from said cap (20); and (c) a tapered surface (47) on said second annular abutment (46) for camming said second abutment (46) over said first abutment (48) into said permanent locking second position of said cap (20) on said collector (32).
Claim 5
Dependent Claim
45 words
The assembly of Claims 1 - 3, further characterized by (a) said cap (20) including an integral centrally positioned well (60) coaxial with the axis of said cap (20); and (b) said well (60) extending into said tubular flow passage (22) of said collector (32).
Claim 6
Dependent Claim

The assembly of Claims 1- 4, further characterized by said means for attaching including (a) a tubular skirt (50) on said collector (18) and integral therewith; and (b) said skirt (50) being coaxial with said tubular flow passage (22) and spaced therefrom; (c) whereby the annular open end (14) of said container (12) is received in press-fit engagement in said space between said collector body (18) and the skirt (50) thereof.
Claim 7
Dependent Claim
79 words
The assembly of claims 3 - 5, further characterized by (a) the first annular abutment (48) adjacent the lower end edge of said tubular skirt (50) and integral therewith; (b) said first annular abutment (48) extending outwardly from the axis of said skirt (50); (c) the second annular abutment (46) adjacent the lower end edge of said cap (20) and integral therewith; and (d) said second annular abutment (46) extending inwardly from said cap (20) toward the axis thereof.
Claim 8
Dependent Claim
31 words
The assembly of Claims 1 - 6, further characterized by (a) a plurality of spaced ribs (40) on the outer surface of said cap (20) for providing a gripping surface thereon.
Claim 9
Dependent Claim
50 words
The assembly of Claims 1 - 7, further characterized by (a) an integral strap (112) connected to said cap; (b) a ring (110) on the end of said strap (112) opposite said cap; and (c) said ring (110) for surrounding said tube-shaped container (12) for preventing loss of said cap.
