Both trained and untrained users may administer an injection safely and conveniently to themselves or others in myriad settings. Certain of the disclosed embodiments rely on the user's manual action to insert the needle. Only after the needle is fully inserted is the medicament delivered, resulting in a safer injection. After use, the devices include a locking mechanism that locks a spring-loaded sheath in place around the needle for protection. As a common syringe is utilized, engineering and production issues of conventional automatic injectors are avoided. ## Claims ### Claim 1 A device for administering medicament using a conventional syringe, the device comprising: a body assembly configured to receive a conventional syringe, the body assembly having a top and an opposing bottom; and a top assembly at the top of the body assembly, wherein the body assembly comprises a sheath, a sheath spring, and a sleeve, and wherein the top assembly comprises a top, a pusher spring, and a pusher. ### Claim 2 (depends on 1) The medicament device of claim 1, wherein the sheath has one or more sheath pins, and wherein the sleeve has tracks configured to receive the one or more sheath pins. ### Claim 3 (depends on 1) The medicament device of claim 1, wherein the body assembly further comprises a body configured to receive the sheath, sheath spring, and sleeve. ### Claim 4 (depends on 3) The medicament device of claim 3, further comprising a cap assembly at the bottom of the body. ### Claim 5 (depends on 1) The medicament device of claim 1, further comprising a cap assembly at the bottom of the top. ### Claim 6 (depends on 1) The medicament device of claim 1, wherein the sheath is substantially the same length as a barrel of a conventional syringe. ### Claim 7 (depends on 1) The medicament device of claim 1, wherein the sheath spring requires less compression force than the pusher spring. ### Claim 8 A device for administering medicament using a conventional syringe, the device comprising: a body assembly configured to receive a conventional syringe, the body assembly having a top and an opposing bottom; and a top assembly at the top of the body assembly; wherein the body assembly comprises a sheath, a locking mechanism, and a sheath spring. ### Claim 9 (depends on 8) The medicament device of claim 8, wherein the locking mechanism comprises a sleeve, sleeve tracks, and one or more sheath pins, wherein the sleeve is slideably disposed at an end opposite the sheath, wherein the sheath pins protrude from the interior of the sheath, and wherein the sleeve tracks are cut within the sleeve and configured to engage the one or more sheath pins. ### Claim 10 (depends on 9) The medicament device of claim 9, wherein the sleeve tracks are bifurcated to lock the sheath in place around a needle of a conventional syringe after use of the device to administer medicament. ### Claim 11 (depends on 9) The medicament device of claim 9, wherein the locking mechanism further comprises sheath snaps extending from the interior of the sheath, and wherein the sheath has sheath fingers extending from one end of the sheath for engaging the sheath snaps. ### Claim 12 (depends on 8) The medicament device of claim 8, wherein the top assembly includes a top, a pusher spring, and a pusher. ### Claim 13 (depends on 12) The medicament device of claim 12, wherein the plunger spring requires more compression force than the sheath spring. ### Claim 14 (depends on 13) The medicament device of claim 13, wherein the body assembly further comprises a body configured to receive the sheath, sheath spring, and sleeve. ### Claim 15 (depends on 8) The medicament device of claim 8, further comprising a cap assembly at the bottom of the body. ### Claim 16 (depends on 12) The medicament device of claim 12, further comprising a cap assembly at the bottom of the top. ### Claim 17 (depends on 8) The medicament device of claim 8, wherein the sheath is substantially the same length as a barrel of a conventional syringe.
