Appl. No.:

11/311585

Inventors:

Daniel L. Shumate - Huntsville AL, US
Paul B. Ruffin - Toney AL, US

International Classification:

A61M 5/00

US Classification:

604173

Abstract:

A microneedle insertable in a target cell tissue, including a manipulative end maintained exterior of cell tissue and an insertion end positionable in or adjacent of target cell tissue. A plurality of microtubes are bundled to pass through the needle body and extend to respective distal ends grouped proximally interior of the insertion end. A sensing fiber is extendable from means for sensing for passage through the needle body to a distal end capable of sensing cell tissue parameters. The insertion end and the bundled microtube and sensing fiber distal ends are positionable in or adjacent of cell tissue thereby providing rapid evaluation of cell parameters by optic fiber sensing, fiber sampling of cell parameters, and precise delivery of therapeutic fluids or additional treatment measures. A method is also disclosed of precisely positioning a microneedle having a plurality of microtubes and sensing fibers therein for evaluating and treating cell tissue.

Abstract:

Apparatus for catching a sample of solid high explosive detonation products hat get ahead of the shock front during the detonation process. The device is passive. The door of the rectangular box of the device is open to allow the passage of solid products ahead of the shockwave into the box. The door to the box is closed mechanically, by pressure applied to both sides of the bent (angled) door. The shockwave is the source of this pressure. A mechanical latch secures the door on closing. The device is made of steel plate and pipe of sufficient thickness to withstand explosive shock.
