The invention relates to an imager system for imaging of a plume of a fugitive gas, dependent upon an electromagnetic wavelength absorption characteristic of the gas. A bi-spectral selector assembly houses first and second filters in separate first and second optical paths for transmittal of electromagnetic energies emanating from the scene of interest. The first and second filters have adjacent mutually exclusive narrow band pass characteristics only one of which corresponds to the electromagnetic wavelength absorption characteristic of the gas. An imager captures first and second image data having traversed the first and second filters in a frame which is then processed by correlating the image data to provide displayable data including an indication of any plume of the fugitive gas. The data is displayed in real time. In one example a CCD video camera provides picture data which is displayed with the image of the plume of gas pasted thereupon.

Imaging of fugitive gas leaks

A flexible isolator bag used to isolate a controlled therapeutic gas atmosphere about a human limb for the management and treatment of wounds and lesions, or an amputation, has a discharge port and a flexible manifold section providing an intake manifold which has an infeed port and inlet openings to the interior of the bag. A self-sealing zipper extends along part of the length of the bag. The bag is secured to the patient by adhesive tape applied to the rim of the open end of the bag. This rim is shaped to prevent a tourniquet effect.
