摘要:
An eyewear system including eyeglasses and a case, the eyeglasses having a first lens, a second lens, and a bendable bridge disposed between the first lens and second lens, the bendable bridge having a spring providing a spring force when the bridge is bent from a rest position, the eyeglasses being adapted to move from a wearable configuration in which the first and second lens do not overlap to a stored configuration in which the first and second lenses at least partially overlap, the bendable bridge being bent from its rest position in the stored configuration, the case having an opening through which the eyeglasses pass during insertion and guides sized and configured with respect to the eyeglasses to engage and fold the eyeglasses against spring force of the bridge to the stored configuration during insertion of the eyeglasses through the opening and into the case.
摘要:
An eyewear system including eyeglasses having first and second lenses; first and second nose pads; and a bridge operably connecting the first and second lenses, the bridge being bendable from a bridge rest position to permit relative movement between the first and second nose pads and providing a bridge pinch force of 50 g or less between the nose pads when the nose pads are moved 7 mm or less from the bridge rest position.
摘要:
Particles of an organic acid salt of an amino acid amide or ester local anesthetic are employed as agents for the improved alleviation of pain. Particularly, the particles find use with surgically created wounds, where the particles may be administered directly into the bed of the wound or topically for transdermal transport.

Cancer patients, patients with cognitive dysfunction, or patients with pulmonary hypertension are treated with parenterally administered therapeutic doses of statins. Particularly, transdermal, injection employing liquid infusion or particles are employed. For cancer, the statins may be used by themselves or in conjunction with a chemotherapeutic regimen. Liver cancer is treated orally with super doses of statins.
摘要:
A tissue expansion device, the device comprising: (a) an expandable compartment adapted for implanting in a body of a subject; and (b) a gas source adapted for implanting in a body of a subject and operably connected to said expandable compartment for inflation thereof by transfer of a gas thereto.
摘要:
An automated portable keratometer includes a hand held housing and is battery powered. A projection system projects collimated light sources at equal converging angles to an optical axis which extends outside the housing. A camera, including an imaging device, and telocentric objective lens are aligned along the optical axis in the housing. The projection system projects a known pattern of collimated light sources onto a patient's eye. The reflected images of these light sources is captured by the camera and imaging device. Derivation of the distances between certain reflected images can be converted by known algorithms into radii of curvature of the eye. Alignment leveling, and other features can be included with the keratometer. The device can also be used to measure other curved surfaces.
摘要:
A check valve for providing fluid communication between a patient's middle ear and external auditory canal for improved comfort and hearing. The check valve is configured for permitting fluid to flow from the external auditory canal into the middle ear and for checking fluid flow from the middle ear to the external auditory canal.
