摘要： An aspiration flow resistor 10 includes an inlet 12 and an outlet 14. A housing 16 is connected to the inlet 12 and outlet 14. A series of spaced walls 18 are disposed between the inlet 12 and the outlet 14. The walls 18 and the inlet 12 and the outlet 14 together with the housing 16 define a plurality of aspiration flow chambers 22. As aspirant flows from the inlet 12 to the outlet 14, a pressure decrease in the aspirant flow occurs at each wall 18 to provide resistance to aspirant flow.

摘要： A fluid flow resistor 10 for use in ophthalmic surgery includes a housing 12 having an inlet 14 and an outlet 16. An elongated turbine 22 is caused to spin within the housing 12 by a flow of fluid which extracts energy from the fluid flow and effectively increases a resistance to fluid flow from the inlet 14 to the outlet 16.

摘要： A phacoemulsification irrigation sleeve 10 is formed of compliant material. The sleeve 10 is for surrounding at least a portion of a phacoemulsification needle 12 and for transporting irrigation fluid between the needle 12 and the sleeve 10. The sleeve 10 includes at least one irrigation port 16 formed in a shaft 18 of the sleeve 10 near a distal end 20 of the shaft 18. An alignment mark 22 of contrasting color relative to a color of the sleeve 10 is placed on the sleeve 10 in a predetermined orientation with respect to the irrigation port 16.

摘要： A safety device in a fluid vent conduit for reducing vacuum level in an aspiration conduit of an ophthalmic surgical system. The device includes an orifice having an inlet for receiving a flow of fluid from an irrigation source. The orifice further has an outlet for directing the flow of fluid into the aspiration conduit. The orifice has a cross-sectional area sufficiently large to ensure an acceptable amount of fluid flows into the aspiration conduit, to reduce the vacuum level in the aspiration conduit, to an acceptable level in an acceptable amount of time and to provide adequate reflux. The cross-section area is sufficiently small to restrict the flow of fluid to allow enough fluid to continue to flow from the irrigation source to a handpiece at a surgical site.
摘要翻译：用于减少眼科外科系统的吸液管道中真空度的流体通气管道中的安全装置。该装置包括具有用于接收来自冲洗源的流体流的入口的孔口。孔口还具有用于将流体流引导到抽吸导管中的出口。孔口具有足够大的横截面积，以确保可接受量的流体进入抽吸管道，以将抽吸管道中的真空水平降低到可接受的时间量内的可接受水平并提供足够的回流。横截面面积足够小以限制流体的流动，以允许足够的流体在手术部位继续从冲洗源流到手持件。
