A safety needle system operable with a medical device includes: a housing with a needle mount having a needle; and a sheath telescopically engaged with the housing and surrounding the needle such that the sheath operates in a retracted position, in which the sheath exposes the needle, and an extended position, in which the sheath surrounds the needle. The sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, transitioning the sheath from the retracted position to the extended position. In one embodiment, the system includes a slider engaged with the sheath and/or housing and including a restraint that engages and disengages the sheath to respectively reinforce and weaken the coupling of the sheath and medical device. In another embodiment, the sheath includes a longitudinal track that slidingly engages a setting of the housing between sheath positions.
1. A safety needle system operable with a medical device, comprising: a housing including a needle mount;a needle having a distal end insertable through the medical device and a proximal end coupled to the needle mount, wherein the medical device comprises a catheter with a catheter hub and the need
1. A safety needle system operable with a medical device, comprising: a housing including a needle mount;a needle having a distal end insertable through the medical device and a proximal end coupled to the needle mount, wherein the medical device comprises a catheter with a catheter hub and the needle is insertable through both the catheter and the catheter hub;a sheath telescopically engaged with the housing and circumferentially surrounding at least a portion of the needle, wherein the sheath operates in: a retracted position that exposes the distal end of the needle; andan extended position, wherein the sheath substantially surrounds the distal end of the needle;wherein the sheath is coupleable to the medical device such that removal of the needle from the medical device transitions the sheath from the retracted position to the extended position;wherein a first inner surface and a second inner surface at a distal end of the sheath are configured to engage a first projection and a second projection on the medical device;wherein the sheath has a first configuration wherein the inner surfaces are inhibited from moving apart and a second configuration wherein the inner surfaces are permitted to move apart to facilitate disengagement from the first and second projections; anda locking mechanism located within the sheath or the housing, the locking mechanism configured to lock the sheath in the extended position, wherein the locking mechanism is configured to abut a portion of the sheath against a portion of the housing, thereby locking the sheath in the extended position. 2. The system of claim 1, wherein the housing includes an inner portion that is contained within the sheath and an outer portion defining an arch that forms a framework external to the sheath, and wherein the inner portion includes a track that facilitates sliding of the housing relative to the sheath. 3. The system of claim 1, wherein the needle is a solid needle. 4. The system of claim 1, wherein the sheath includes a holding tab extending laterally outward from a distal portion of the sheath, wherein the holding tab is configured to assist a user in manipulating the housing away from the medical device. 5. The system of claim 1, wherein the sheath includes a tab having a tabbed end, wherein the stop at the housing includes a catch configured to engage the tabbed end, and wherein the locking mechanism is configured to facilitate engagement of the tabbed end against the catch in the extended position of the sheath. 6. The system of claim 1, wherein the sheath includes one or more split portions. 7. The system of claim 6, wherein the one or more split portions are configured to separate such that the separation of the split portions enables the system to release from the medical device. 8. The system of claim 1, further comprising a restraint, wherein the restraint is configured to engage with the sheath in the retracted position, thereby reinforcing coupling of the sheath to the medical device in the retracted position. 9. The system of claim 1, further comprising a restraint, wherein the restraint is configured to disengage from the sheath in the extended position, thereby weakening the coupling of the sheath to the medical device in the extended position. 10. The system of claim 1, further comprising a restraint configured to reinforce the coupling of the sheath to the medical device in the retracted position. 11. The system of claim 1, further comprising a restraint configured to weaken the coupling of the sheath to the medical device in the extended position. 12. The system of claim 1, wherein the locking mechanism includes a tab and a stop. 13. The system of claim 12, wherein the tab is on the sheath and the stop is on the housing. 14. The system of claim 1, wherein the locking mechanism is on the housing. 15. The system of claim 1, wherein the locking mechanism is on the sheath. 16. The system of claim 1, wherein the sheath is telescopically engaged with the housing in both the retracted position and the extended position. 17. The system of claim 1, wherein the first and second surfaces at the distal end of the sheath are disposed on opposing walls of the sheath.
