Claims
- 1. A device for inserting a bone-piercing needle port into bone, comprising:
- a main housing which includes an aperture at a front end of said main housing;
- a trigger needle having a forward end and a rear end, wherein said rear end is coupled to a trigger release mechanism mounted upon said main housing and said forward end is adapted during use to penetrate soft tissue and activate said trigger release mechanism upon bearing against a bone underlying said soft tissue; and
- a bone-piercing needle configured within said main housing, wherein said bone-piercing needle is coupled to said trigger release mechanism to releasibly extend through said aperture and into said bone during activation of the trigger release mechanism.
- 2. The device as recited in claim 1, wherein said bone-piercing needle is adapted to releasibly extend with sufficient momentum at the point of impact to penetrate bone and reside partially within a bone marrow cavity of said bone.
- 3. The device as recited in claim 1, wherein said bone-piercing needle comprises a bore and at least one orifice extending into said bore from the side of the bone-piercing needle.
