Abstract: A catheter protection device and method for securing a catheter to a patient's body to prevent the unauthorized and possibly traumatic removal of a catheter. The device is thin, breathable and not easily removed by an agitated or mentally incompetent patient. The device is constructed of a base, adhesives, and a sleeve. The edges of the base each contain a section of adhesive wherein mid-portion of the base remains uncovered by adhesive. The open sleeve is permanently attached to an edge of the base. Once a catheter has been placed in an open sleeve, the sleeve will be folded such that the rear portion of the sleeve attached to the nearest edge of the base creating a closed sleeve surrounding the catheter. The catheter protection device may be placed against a patient's body with the adhesive edges of the base and an adhesive covered catheter sleeve adjacent to a patient.

Abstract: Methods and apparatus for extracting gas samples from a particle-laden fluid stream are disclosed. An exemplary sampling probe apparatus includes a probe head having an upstream face and a downstream face, an intake orifice inwardly tapering from the upstream face into a central bore region of a cavity within the probe head, and an outlet orifice outwardly tapering from said central bore region to the downstream face, so as to permit fluid gas flow through the central bore region of the cavity. A filter device disposed within the cavity of the probe head extends between the intake orifice and the outlet orifice so as to divide a low-pressure sampling region of the cavity from the central bore region. A sampling tube in fluid communication with the low-pressure sampling region provides for extracting gas samples from the low-pressure sampling region of the cavity.
