Seal 114 is preferably releasibly, adhesively affixed to barrel assembly 110 over opening 126 and provides a sterile barrier and tamper indicator until removed from barrel assembly 110 for use. Preferably seal 114 comprises a tab 132 which provides for facile removal to seal 114. Seals for similar purposes are well known and widely used in the medical device field. To prepare system 100 for use in a medical procedure, seal 114 and protector 112 are simply removed from barrel assembly 110, as seen in FIG. 6. Note that barrel assembly 110 has been rotated 180.degree. relative to its position in FIG. 5. With cover removed. an extendable needle sheath or shroud 140, generally numbered in other figures as 140', is seen to be disposed about a medical needle 40. Note that, in this embodiment, needle 40 is securely affixed to barrel 124. Attachment of needle 40 to barrel 124 is disclosed in more detail hereafter.
Intermediate dispositions of parts 150, 160 and 170 as continuing distally directed force is applied to comer 182 are seen in FIG. 7B and 7C. Successively, distal application of force causes, in sequence, disposition of parts 150, 160 and 170 of shroud 140 as seen in FIG. 7B and subsequently as seen in FIG. 7C. Note that, as line 184' (ledge member 184) is moved into contact with needle 40, Rotation of part 150 relative to hub 180 is translated into rotation of part 160 through hinge 162. Consequently, part 170 is directed superiorly through hinge 172 until line 186' (ledge member 186) is raised to contact needle 40. Upon contact of line 186' against needle 40, part 170 is rotated in clockwise fashion to extend face 206 to be distally disposed relative to needle tip 44. As seen in FIG. 7D, further rotation of part 150 to a substantially parallel disposition relative to needle 40 results in similar disposition of parts 160 and 170. To assure forces directed upon comer 182 always result in extension of part 170, part 170 should not form an angle (indicated by arc and arrow 188) of equal to or less than 90.degree.. An extended foot 189, seen in FIG. 7, provides extension which functions to provide a linear offset which results in an angular bias to protect against binding when angle 188 is less than 90.degree.. Further, protruding latches 210 and 212, described hereafter, may be used for further bias. A stop 221, seen protruding from face 142 of barrel 124 provides a similar bias, retarding part 160 from binding against needle 40 as corner 182 is displaced distally.
