Abstract A rapid vascular drug delivery device, system and method is provided having a releasibly extending and retracting needle necessary for injecting and withdrawing fluid into and from a physiological or non-physiological cavity. Accordingly, the needle can be releasibly extended with sufficient momentum at a point of impact to penetrate a hard substance such as bone. The needle is slideably placed within an aperture configured at the forward end of a main housing, wherein a trigger needle can be arranged proximate to the forward end in order to detect tissue thickness or bone depth necessary for ensuring accurate placement of the bone-piercing needle within the bone marrow. The needle can receive fluids interspersed by parallel-placed or series-placed fluid containers configured within the main housing. Thus, more than two dissimilar types of fluids or medicants can be pre-loaded into the device and delivered to the subject in order to enhance dissemination of, for example, a resuscitating drug deep within and throughout the bone marrow.
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.

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.
Claim 3
Dependent Claim
38 words
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.
Claim 4
Dependent Claim
