    摘要: An ultrasonic core including a longitudinally elongated, generally planar waveguide defining an aperture extending from a first side of the waveguide toward a medial plane of the waveguide, and having a transducer element sized and shaped so as to substantially conform to the size and shape of the aperture and to be at least partially embedded within the waveguide. In other aspects, an ultrasonic core including a longitudinally elongated, generally planar silicon waveguide having at least one transducer element secured thereto and a wedge-shaped acoustic horn including an inclined side surface, characterized in that the inclined side surface is oriented along the {1,1,1} crystallographic plane of the silicon material. Also, methods of manufacturing the respective ultrasonic cores and ultrasonic handpieces for an ultrasonic surgical instruments incorporating such cores.

    摘要: A thermal flow sensor has a first substrate, second substrate and a third substrate, each of which has a first side and a second opposite side. The first substrate is connected to the second substrate such that the second side of the first substrate abuts the first side of the second substrate. The third substrate is connected to the second substrate such that the second side of the second substrate abuts the first side of the third substrate. The second substrate has a groove formed therein so as to form a conduit bounded by the second substrate and the second side of the first substrate and the first side of the third substrate. A heater is disposed on the first side of the first substrate opposed to the conduit. A first temperature sensor is disposed on the first side of the first substrate opposed to the conduit.

    摘要: An erosion-resistant capillary chip for use with in an infusion pump that is made from a silicon substrate having a first surface that includes a micro groove etched therein and a glass plate laminated to the first surface. The glass plate covers the micro groove so that a micro fluid conduit is created. The glass plate includes an inlet bore that connects with the micro fluid conduit and the silicon substrate includes an outlet bore that connects with the micro fluid conduit so that a drug solution entering the inlet bore from the infusion pump may pass through the micro fluid conduit at a restricted flow rate to the outlet bore and thereafter to a target site of a patient. The micro groove includes a passivation layer made from silicon nitride or silicon carbide that protects the micro groove against erosion from passing fluids having high basic or high acidic pH levels. A method for making the capillary chip is disclosed, as well as an infusion pump incorporating the improved capillary chip.
