摘要： The present disclosure relates in general to an apparatus and method for priming a liquid or surgical cassette. In one embodiment, an infusion system within the liquid cassette is primed using a forward flow of a liquid and a backward flow of the liquid. The forward flow of the liquid creates a first volume of liquid stored within an infusion conduit, which is connected to an infusion chamber via a first valve. The infusion conduit has an infusion port exposed to a non-liquid environment having a first pressure. A second pressure is created in the infusion chamber that is lower than the first pressure. Opening the first valve causes a second volume of liquid within the infusion conduit to flow over the first valve and towards the infusion chamber. The second volume of liquid is less than or equal to the first volume of liquid.

摘要： A continuous high resolution fluid level monitoring system is provided by embodiments of the present invention. This continuous high resolution fluid level monitoring system includes a unique fluid level sensor having a point light source, parabolic reflector, sensor array, and detection, processing and control system. The point light source illumines a parabolic reflector wherein the point light source is located at the focus of the parabolic reflector. The parabolic reflector reflects light from the point light source to produce a parallel light curtain. This parallel light curtain is parallel to an axis of symmetry of the parabolic reflector. The parallel light curtain illumines a chamber such as a chamber in an ophthalmic surgical device used to contain surgical fluid. The sensor array coupled to the chamber detects the parallel light curtain illuminating the chamber. The sensor array provides an output to a detection/processing/control system in order to determine the fluid level within the chamber. This optical method of determining the surgical fluid levels may be advantageous in that it prevents physical contamination of the surgical fluids.

摘要： Embodiments of the present invention provide a system and method for detecting the level of a fluid in a surgical cassette by projecting light from a linear light source into a wall of a cassette. Depending on the amount a light reflected or refracted in the cassette (i.e., due to the cassette material/fluid interface or cassette material/air interface (or other interface)) various portions of a linear sensor array will be more or less illuminated. By examining the illumination of the linear sensor array, the level of fluid in the chamber can be determined.

摘要： Embodiments of the present invention provide an apparatus and method controlling the flow of aspiration fluid in an aspiration chamber of a surgical cassette. One embodiment of the present invention provides an aspiration chamber having an aspiration port positioned at or close to the bottom of the chamber. When the aspiration fluid enters the aspiration chamber from below the fluid surface (e.g., from a port located at the bottom or on a sidewall close to the bottom), it does not create disturbance at the liquid/air interface and thus does not disturb the continuous level sensing. Also, since the aspiration port is placed at or very close to the bottom of the aspiration chamber, the liquid inside the chamber can be fully used for sustained reflux and push priming.
摘要翻译：本发明的实施例提供了一种控制外科手术盒的抽吸腔中的抽吸流体的流动的装置和方法。本发明的一个实施例提供了一种具有位于或靠近腔室底部的抽吸口的抽吸室。当吸入流体从流体表面的下方（例如，位于底部的端口或靠近底部的侧壁）进入抽吸室时，其不会在液体/空气界面处产生干扰，因此不会干扰连续水平传感。此外，由于吸入口位于或非常接近抽吸室的底部，所以室内的液体可以被充分地用于持续回流和推动启动。

摘要： A surgical cassette have a rigid fluid channel formed into a rigid plastic component or housing. The piezoelectric crystals of an ultrasonic flow meter are positioned on one side of the fluid channel. The side wall of the fluid channel opposite the piezoelectric crystals is exposed to fluid in the flow channel on its interior side and is exposed to ambient air on its exterior side. The interface between the wall and the air acts as an acoustic reflector for the operation of the ultrasonic flow meter.
