发明名称 HANDHELD OCULAR ASPIRATION TOOL
摘要 A variety of systems, processes, and techniques may provide ocular aspiration. In certain implementations, a handheld ocular aspiration tool may include an electrical motor, a peristaltic pump assembly, a fluid input port, and a fluid output port. The peristaltic pump assembly may include a helically wound compressible conduit and a plurality of variable radius rollers. The rollers may be configured to increasingly occlude the conduit as the rollers are rotated in contact with the conduit, wherein two rollers substantially occlude the conduit at one time to pump fluid through the conduit. The fluid input port may be in fluid communication with an input end of the peristaltic pump assembly, and the fluid output port may be in fluid communication with an output end of the peristaltic pump assembly.

主权项 1. A handheld ocular aspiration tool comprising: an electrical motor; a peristaltic pump assembly comprising: a helically wound compressible conduit; andat least one variable radius roller, the at least one variable radius roller configured to increasingly occlude the conduit as the roller is rotated in contact with the conduit, the at least one variable radius roller operable to substantially fully occlude the conduit at one time to pump fluid through the conduit; a fluid input port in fluid communication with an input end of the peristaltic pump; and a fluid output port in fluid communication with an output end of the peristaltic pump.
