A single-use needle cover configured to obscure, protect, or hide at least a portion of a needle from view before, during, and/or after an injection and/or aspiration procedure is disclosed. In some embodiments, the cover includes a housing at least partially containing the needle and configured to couple to a syringe, wherein the housing includes an axis and a guide member. In some embodiments, a sleeve has a plurality of tracks configured to slidingly receive the guide member, wherein the sleeve is configured to retract, extend, and rotate with respect to the housing. In some embodiments, after the sleeve has been retracted and extended one time, a first locking member inhibits further retraction of the sleeve and a second locking member inhibits rotation of the sleeve.

1. An automatically locking needle cover comprising: a housing configured to couple with a medical instrument, the housing comprising a locking member with an axial length;a needle comprising a distal end and a proximal end; anda sleeve that is slidably receivable within the housing and slidably movable over the needle, the sleeve comprising a flange with a notch, the sleeve being moveable relative to the housing and needle from an extended position to a retracted position to a locked position;wherein: in the extended position, the sleeve is circumferentially oriented relative to the housing such that the notch in the flange is substantially circumferentially aligned with the locking member;in the course of movement of the sleeve from the extended position to the retracted position: the flange moves proximally relative to the housing and the needle;the locking member axially passes through the notch; andthe sleeve rotates relative to the housing such that the notch in the flange is out of circumferential alignment with the locking member;in the retracted position, the distal end of the needle is exposed;in the course of movement of the sleeve from the retracted position to the locked position: the flange moves distally relative to the housing and the needle;the flange deflects the locking member from an undeflected position to a deflected position; andin response to the flange moving distally beyond the axial length of the locking member, the locking member resiliently returns to substantially the undeflected position; andin the locked position: a portion of the sleeve extends distal of the distal end of the needle and inhibits access to the distal end of the needle; andthe locking member provides a physical interference to proximal movement of the sleeve relative to the housing and the needle, thereby inhibiting the distal end of the needle from being reexposed. 2. The automatically locking needle cover of claim 1, wherein a distal tip of the sleeve comprises stimulation features configured to engage the skin of a patient prior to a distal tip of the needle contacting the skin of the patient, whereby the stimulation features reduce pain by stimulating the patient's pressure-receptor nerves. 3. The automatically locking needle cover of claim 2, wherein the stimulation features comprise a plurality of bumps. 4. The automatically locking needle cover of claim 1, wherein the flange deflects the locking member radially outwardly. 5. The automatically locking needle cover of claim 1, wherein: the housing comprises a plurality of locking members and the flange of the sleeve comprises a corresponding plurality of notches; andin the extended position, the sleeve is circumferentially oriented relative to the housing such that the each of the notches is substantially circumferentially aligned with a corresponding one of the locking members. 6. The automatically locking needle cover of claim 1, wherein, in the course of movement of the sleeve from the extended position to the retracted position, the flange engages a second locking member, the second locking member configured to facilitate substantially one-way rotation of the sleeve relative to the housing. 7. The automatically locking needle cover of claim 1, wherein the locking member comprises an arm with a distal end and a proximal end, the distal end of the arm being positioned radially inward of the proximal end of the arm when the sleeve is in the extended and locked positions. 8. The automatically locking needle cover of claim 1, wherein the locking member comprises a means for axially locking the sleeve. 9. The automatically locking needle cover of claim 1, wherein the proximal end of the needle is secured with and contained in the housing. 10. The automatically locking needle cover of claim 1, wherein the needle is substantially completely obscured from view when the sleeve is in the extended position and the locked position. 11. The automatically locking needle cover of claim 1, wherein the housing further comprises a shoulder that provides a physical interference to distal movement of the sleeve relative to the housing and the needle when the sleeve is in the locked position. 12. The automatically locking needle cover of claim 1, further comprising a cam mechanism configured to convert a proximally-directed force applied to a distal tip of the sleeve into rotation and translation of the sleeve relative to the housing and the needle. 13. The automatically locking needle cover of claim 1, wherein the medical implement comprises a syringe. 14. A method of manufacturing an automatic locking needle cover having an axial axis, the method comprising: obtaining a proximal portion of a housing;obtaining a distal portion of the housing, the distal portion comprising a distal opening;obtaining a sleeve comprising a flange;wherein one of the sleeve and the distal portion of the housing comprise a guide member, and the other of the sleeve and the distal portion of the housing comprise first and second tracks that are substantially parallel with the axial axis, the first track comprising an insertion portion and a radially inclined portion;inserting the sleeve through the distal opening of the distal portion of the housing such that the guide member enters the insertion portion of the first track;sliding the guide member the axial length of the insertion portion of the first track;sliding the guide member up the radially inclined portion;sliding the guide member axially beyond the radially inclined portion, thereby moving the guide member out of the insertion portion of the first track;sliding the guide member in the first track a distance such that the guide member is proximal of, and axially spaced apart from, the radially inclined portion;engaging the sleeve with the distal portion of the housing, whereby the engagement inhibits further distal movement of the sleeve relative to the distal portion of the housing; andcompressing a biasing member between the sleeve and the proximal portion of the housing, thereby energizing the biasing member and biasing the sleeve. 15. The method of claim 14, further comprising verifying that, when the sleeve is moved proximally relative to the housing: a stop portion of the first track inhibits the guide member from reentering the insertion portion; andthe stop portion directs the guide member into a transfer track in the other of the sleeve and the distal portion of the housing. 16. The method of claim 15, further comprising verifying that, when the sleeve is moved further proximally relative to the housing, the guide portion exits the transfer track and enters the second track. 17. The method of claim 14, wherein the proximal and distal portions of the housing are separate components, and the method further comprises joining the proximal and distal portions. 18. The method of claim 14, further comprising securing a needle with the proximal portion of the housing. 19. The method of claim 14, wherein obtaining the proximal portion comprises molding the proximal portion, obtaining the distal portion comprises molding the distal portion, and obtaining the sleeve comprises molding the sleeve. 20. The method of claim 14, wherein engaging the sleeve with the distal portion of the housing comprises abutting the sleeve with the distal portion of the housing. 21. The method of claim 14, wherein the guide member moves relative to the second track.
