inches to 0 60 inches tapered portion of handle 25 has an inner and an outer diameter that varies with the tapered portion of a particular needle being formed however the range of outer diameters of the tapered portion may range from 0 20 inches to 0 30 inches similarly the inner diameter of the tapered portion may range approximately from 0 15 inches to 0 25 inches the first stepped portion of handle 25 has an outer diameter that ranges from approximately 0 30 inches to 0 40 inches and the inner diameter ranges from approximately 0 25 inches to 0 35 inches second stepped portion of handle 25 has an outer diameter that ranges from 0 25 inches to 0 35 inches and an inner diameter that ranges from approximately 0 20 inches to 0 30 inches and a length that ranges from approximately 0 25 inches to 0 75 inches needle 40 may have a length that ranges from approximately 0 70 inches to 2 5 inches an outer diameter that ranges from approximately 0 10 inches to 0 02 inches it will be appreciated that a solid tip needle lacks the inner diameter dimensions listed for the proximal portion of handle 25 flange 30 the tapered portion of handle 25 the first and second stepped portions of handle 25 in fig7 needle 40 that is formed has a solid tip but a surface groove is formed therein surface groove 60 allows blood to enter needle 40 at or near the distal end of needle 40 the blood moves in the proximal direction of needle 40 as shown in fig7 it will be appreciated that the surface groove.
