Pen needle sharps port
View Patent ↗The present invention is a mechanical contrivance integrated into the closure of a sharps collector. It is intended to allow for the safe removal and disposal of a used pen needle from a pen syringe device. The pen syringe, with the used pen needle attached, is inserted into the specially designed port of the present invention. The pen syringe is then rotated counterclockwise about its longitudinal axis. The pen needle itself is constrained by at least one tooth, which only allows the pen needle one degree of freedom (linear displacement along its longitudinal axis). These conditions cause the pen needle to be unthreaded from the pen syringe, such that when the pen syringe is withdrawn from the port, a tang then blocks the pen needle from being withdrawn with the pen syringe, and the used pen needle falls into the sharps collector without the use of a secondary operation.
1. A closure for a sharps container for the disposal of a needle comprising:
a. a top surface and a bottom surface wherein said bottom surface is on an interior of said sharps container;
b. a passage located between said top surface and said bottom surface for the transfer of said needle into said sharps container;
c. disposed within said passage is a plurality of teeth for partially encircling said needle, said teeth being disposed for engaging said needle to prevent rotation of said needle about a center axis of said passage and being disposed in an arcuate path about said center axis; and
d. disposed within said passage is a tang, said tang being disposed for engaging said needle to prevent translation of said needle along said center axis, wherein said teeth and said tang do not impede the transfer of said needle into said sharps container by gravitational action.
2. The closure according to claim 1 wherein said center axis is at an angle substantially less than 90 degrees to said top surface.
3. The closure according to claim 1 wherein said tang is cantilevered.
4. The closure according to claim 1 wherein said plurality of teeth extend around said passage less than half of said passage's circumference.
5. The closure according to claim 1 wherein said closure has a handle.
6. The closure according to claim 1 wherein said closure contains an integrally molded lid.
7. The closure according to claim 1 wherein said passage includes indicia for advising a patient as to the proper removal of said needle.
8. The closure according to claim 1 further comprising a pair of tangs for engaging said needle to prevent translation of said needle along said center axis, wherein said pair tangs are disposed opposing each other within said passage.
9. The closure according to claim 8 wherein said pair of tangs are cantilevered.
10. A closure for a sharps container for the disposal of a needle comprising:
a. a top surface and a bottom surface wherein said bottom surface is on an interior of said sharps container;
b. a passage located between said top surface and said bottom surface for the transfer of said needle into said sharps container;
c. disposed within said passage is a plurality of teeth for partially encircling said needle, said teeth being disposed for engaging said needle to prevent rotation of said needle about a center axis of said passage, wherein said center axis is at an angle substantially less than 90 degrees to said top surface and said teeth are disposed in an arcuate path about said center axis; and
d. disposed within said passage is a pair of tangs, said pair of tangs being disposed for engaging said needle to prevent translation of said needle along said center axis, wherein said teeth and said tangs do not impede the transfer of said needle into said sharps container by gravitational action.
