20110076138 | Aspirator Insert for a Boundary Layer in a Fluid, a Wall and a Compressor Equipped with Said Insert - A passive leakage device for an axial turbomachine, more particularly for a low-pressure compressor of an axial turbomachine, is adapted to reduce and/or eliminate the surging phenomenon within the machine. The passive leakage device includes an insert having a general cylindrical shape with a flange at one end and a bottom or membrane at the other end. The membrane comprises two cross-shaped notches, the notches being adapted to enable a deformation of the membrane under a pressure exceeding a predetermined threshold, so as to allow a leakage to go through the membrane. Several inserts are arranged through the wall of a compressor casing, distributed over one or several circumferences of the casing, facing one or several rows of rotor blades. In the case of a double-flow turbomachine, such as a jet engine, the beak for separating the primary and secondary flows is used to form a chamber for communication between the inserts and for compensation with the pressure present in the secondary flow. | 03-31-2011 |

20140060547 | INTRAVENOUS EXTREMITY SUPPORT - Embodiments for intravenous extremity supports for pediatric and adult patients that allow health care workers to visually assess and/or palpate an extremity during IV therapy without removing the extremity support are disclosed. Embodiments of extremity supports comprise a stabilizer and at least one window. In one embodiment, the window is a transparent portion of the stabilizer. In another embodiment, the window is an opening in the extremity support. In yet another embodiment, a window is an area of the extremity support that does not impede a health care worker's view of the lower part of an extremity. | 03-06-2014 |

20110288486 | SITE GUARD FOR INTRAVENOUS SITES AND OTHER SENSITIVE AREAS - A multipurpose site guard for use at all peripheral and central venipuncture infusion sites, sensitive areas, and for pediatric and adult patients. The guard is a hollow plastic member with a base and a sidewall that forms a cover over the site. Improvements to this invention include holding the guard in place with a fabric connector having closure means, cushioning the guard's base with a soft material, and a hole disposed in the hollow member for providing access to the site. | 11-24-2011 |
