Integrally molded part phlebotomy safety devices are disclosed which require only the integrally-molded part, a medical needle, a label and a transport needle cover to form a ready-to-use phlebotomy device. Upon removal of the label and needle cover, the device is ready for use in a medical procedure. The enclosure comprises a plurality of rigid segments serially connected by a plurality of intersegment hinges, which are preferably living hinges. The segments are disposed about a medical needle, folded upon each other during the medical procedure and extended at the end of the procedure to form a secure, substantially rigid safety shroud. During the procedure, the enclosure is folded and conveniently disposed about a proximal portion of the needle. At the end of the procedure, the enclosure is extended to protectively sheath and secure the needle in a substantially rigid structure formed in combination by the enclosure and the needle.
What is claimed and desired to be secured by Letters Patent is: 1. A safety apparatus for sheathing a medical needle, said apparatus comprising:a hollow bore cannula securely affixed in a hub and having at least one sharpened tip to form the medical needle; a part hingeably joined to said hub, said part comprising an elongated sheath which comprises a plurality of serially interconnected substantially rigid segments each of which is interconnected to at least one adjacent segment by a hinge, at least a distally disposed segment comprising an open orifice, through which said cannula passes to form a pivotal axis of intersection about the cannula, and a channel in which the cannula is disposed when the sheath is extended, said sheath and said hinges being disposed to permit folding of the sheath about the cannula in a first state to permit usable access to said sharpened tip in a medical procedure and extending of the sheath, while sliding and pivoting the distal segment relative to the cannula, to a substantially planar disposition along said cannula whereat the cannula is disposed along the channel, said sheath further comprising at least one latching member which catches and securely affixes the cannula relative to the sheath, said sheath and cannula, in combination, thereby forming a substantially rigid body which protectively encloses said sharpened tip and denies access thereto. 2. Safety apparatus according to claim 1 wherein a segment which encloses said sharpened tip comprises a closure of its channel distal from the sharpened tip.
DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS In this description. unless a specific object is referenced, the term proximal is used to indicate the segment of a device normally closest to a user (the clinician or technician who is treating a patient). In like manner, the term distal refers to the other (away from the user) end. Reference is now made to the embodiments illustrated in FIGS. 1-19 wherein like numerals are used to designate like parts throughout. In some cases, parts having similar form and function to parts earlier cited are enumerated with prime numerals of earlier cited parts.
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 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 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 90 212, 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.
PRIOR ART Problems associated with inadvertent needle sticks are well known in the art of blood sampling, percutaneous medication injection and other medical procedures involving uses of medical needles. Ever increasing attention is being paid to needle stick problems due to the contemporary sensitivity of exposure to AIDS, Hepatitis and other serious blood-bome diseases.
