摘要： An ophthalmic device and system for measuring relative pressure of fluid inside an ocular globe includes an elongated surgical instrument which is adapted to penetrate the ocular globe. A fluid pressure transducer is mounted on the instrument in a position to communicate with fluid inside the ocular globe and generate signals in response to pressure changes in the fluid. The signal is transmitted external of the instrument to a pump or other fluid transfer device which is operatively connected to the transducer for receiving the signals and supplying or removing fluid from the ocular globe in response to predetermined signals. A conduit is operatively connected to the fluid transfer device and adapted to communicate with the interior of the ocular globe through which fluid can flow between the fluid transfer device and the ocular globe.

摘要： An expandable polymer concrete or mortar composition, and process for producing it, which allows the use of low temperature cure resins by incorporating a substituted mineral which is able to expand in the polymer concrete mix so that the dilation of the mineral will counteract the shrinking effect of the curing resin. The substituted mineral may be selected from the montmorillonite group and is produced by substituting its water of hydration with a higher volatility composition such as ammonia.

摘要： An ophthalic device and system for measuring and controlling relative fluid pressure inside an ocular globe includes a surgical instrument which is adapted to penetrate the ocular globe. A fluid pressure transducer is mounted on the instrument so that when the instrument penetrates the ocular globe the transducer is located adjacent to an opening that communicates with the interior of the globe so that it can react to pressure changes in the fluid therein and generate signals in response to changes in the pressure of the fluid. The signal is transmitted external of the instrument to a control system which is operatively connected to the transducer for first receiving signals from the transducer and the controlling a fluid supply system in response to signals according to a predetermned set of instructions. The control system is connected to a closed loop feed system in which fluid is continuously circulated. Fluctuations in intraocular pressure cause the control system to divert fluid from the feed system to the ocular globe to a conduit connected to the closed loop.

摘要： Polymeric foams with novel chemical compositions are prepared by the condensation of specially-synthesized precursors, which contain (in addition to carbon and hydrogen) one or more of the following elements: oxygen, fluorine, nitrogen (in structures with stable chemical bonds), silicon, boron, phosphorus (in high oxidation states), and certain metals (and/or their oxides and hydroxides). Upon mixing in the proper proportions and/or heating these precursors react rapidly to generate polymeric networks, consisting of heterocyclic crosslink centers, connected with heterochain segments; hydrogen is largely eliminated or replaced by fluorine. These structures possess inherent nonflammability and high thermoxidative stability. Foaming is effected by the gaseous by-products of the condensation reactions, as well as by the addition of foaming agents. The resulting foam products can be formulated to have a wide range of densities and flexibilities.
