    摘要: A portable lavage apparatus for irrigating or washing wounds is disclosed. The apparatus includes a fluid bag, a spring bias mechanism, and a hose. The spring bias mechanism is typically configured to store potential energy or produce kinetic energy used for urging fluid from the fluid bag, through the hose, and toward a wound. The invention has particular advantages in military or civilian environments in that it allows prompt treatment of wounds. Additionally, the lavage apparatus is small enough to be carried by individuals and does not require an external source of power. Accordingly, the portable lavage apparatus may be employed even on battle fields or in remote areas to treat wounds.

    摘要: The invention relates to a design for securing tubes, catheters, drains, or other tubular medical devices within the body of a mammal, for example a human, and methods of securing same. The invention includes a first tubular body and at least one second tubular body. The first tubular body includes an outer surface, an inner surface defining a lumen extending longitudinally at least partially through a length of the tubular body, a wall at least partially defined by the outer surface and the inner surface, and a longitudinal axis. The at least one second tubular body includes an outer surface, an inner surface defining a lumen extending longitudinally through the second tubular body, and a wall at least partially defined by the outer surface and the inner surface. The second tubular body is disposed through the wall of the first tubular body transversely to the longitudinal axis.

    摘要: A process for treating an underground formation, which process comprises: (a) introducing into the underground formation a treatment fluid comprising an organic acid precursor; (b) heating a zone within the formation, which zone contains at least a portion of the organic acid precursor, to a temperature which is above the natural formation temperature and sufficient to increase the rate of hydrolysis of the organic acid precursor; and (c) allowing the organic acid precursor to hydrolyse to produce an organic acid in an amount effective to acidize the underground formation.
