Method of and apparatus for tunable gas injection in a plasma processing system

A method of and apparatus for providing tunable gas injection in a plasma processing system (10, 10′). The apparatus includes a gas injection manifold (50) having a pressurizable plenum (150) and an array of adjustable nozzle units (250), or an array of non-adjustable nozzles (502, 602), through which gas from the plenum can flow into the interior region (40) of a plasma reactor chamber (14) capable of containing a plasma (41). The adjustable nozzle units include a nozzle plug (160) arranged within a nozzle bore (166). A variety of different nozzle units are disclosed. The nozzle plugs are axially translatable to adjust the flow of gas therethrough. In one embodiment, the nozzle plugs are attached to a plug plate (154), which is displacable relative to an injection plate (124) via displacement actuators (170) connecting the two plates. The displacement actuators are controlled by a displacement actuator control unit (180), which is in electronic communication with a plasma processing system control unit (80). The gas flow into the chamber interior region is preferably controlled by monitoring the pressure in the plenum and in the chamber and adjusting the nozzle units accordingly. Where the nozzle units are not adjustable, a portion of the nozzles are sized to a first flow condition, and another portion of the nozzles are sized to a second flow condition.

Devices, systems and methods for extracting bodily fluid and monitoring an analyte therein

A system for extracting a bodily fluid sample (e.g., an interstitial fluid [ISF] sample) and monitoring an analyte therein includes a disposable cartridge and a local controller module. The disposable cartridge includes a sampling module adapted to extract a bodily fluid sample and an analysis module adapted to measure an analyte (e.g., glucose) in the bodily fluid sample. The local controller module is in electronic communication with the disposable cartridge and is adapted to receive and store measurement data from the analysis module. An ISF extraction device includes a penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently, extracting an ISF sample therefrom. The device also includes a pressure ring(s) adapted for applying pressure to the user's skin layer in the vicinity of the target site. The device is configured such that the pressure ring(s) is capable of applying pressure in an oscillating manner whereby an ISF glucose lag of the ISF sample extracted by the penetration member is mitigated. A method for extracting ISF includes providing an ISF fluid extraction device with a penetration member and a pressure ring(s). Next, a user's skin layer is contacted by the pressure ring(s) and penetrated by the penetration member. An ISF sample is then extracted from the user's skin layer while pressure is being applied in an oscillating manner by the pressure ring(s). The oscillating pressure mitigates an ISF glucose lag of the extracted ISF sample extracted.
