Abstract: A universal passive protector for an IV catheter is provided. The protector comprises an over-the-needle catheter including a proximal hub. The hub is secured within a hub trap comprising first and second interlocking arms. The hub trap is secured to a distal end of a tubular sheath. A slider is disposed about the sheath, and connected to a proximal end of the needle through a slit in the sheath. When the slider is in a distal position, the needle maintains the arms in a closed configuration wherein the hub is secured to the hub trap. When the slider is moved to a proximal position, the needle moves to a proximal position wherein the needle no longer maintains the arms in a closed position. The arms snap to an open position, releasing the hub and trapping the sharp distal tip of the needle within the sheath. Medical technicians are thus protected against accidental needle sticks.

Abstract: Disclosed herein are embodiments of a tire pressure indicator (30) for providing indication of a tire's pressure. The indicator (30) may include first and second indicators (82, 104) corresponding to first and second ranges of tire pressures. The indicator (30) may also include a rolling diaphragm (58) that actuates display of the first or second indicators (82, 104). The indicator (30) may include a plurality of channels (78) that permit communication of air between an exterior portion of the indicator (30) and an interior portion of the indicator (30) and a filter (96) that permits air therethrough, but prevents moisture from passing therethrough.

Abstract: An improved electrode for use in medical procedures requiring tissue removal. At least one gear shaped element is provided and mounted onto a distal tip region of a wire loop electrode. The gear shaped element distributes current at a tissue/electrode interface and enables the electrode to cut through substantial quantities of tissue while simultaneously creating a substantial rim of coagulation within an area of cut tissue.
