FIELD: medical equipment.
SUBSTANCE: group of inventions relates to medicine. Ophthalmic pump system comprises: a cavity defining the cavity; rotating element located in housing cavity; flexible tubular structure located in housing nearby rotating element, so that rotation of rotary element pushes fluid through flexible tubular structure; and a lubricating solution disposed in the cavity around the rotating member and at least a portion of the flexible tubular structure. At the same time the flexible tubular structure contains the first tubular element and the second tubular element, at least partially located near to the rotating element so that the rotating element simultaneously is in contact with elements. First and second tubular elements are located around the body. Ophthalmic pump system additionally comprises a channel extending circumferentially around the body, wherein the channel is in fluid communication with the first and second tubular elements. Ophthalmic lubricating set for use with an ophthalmic pump system, comprising: a body defining a cavity configured to be filled with a lubricating solution and an insert of a rotating element. Method for assembling an ophthalmic pump system includes: obtaining a housing; filling cavity with lubricating solution; inserting rotary element into cavity filled with lubricating solution; actuation of rotary element, so that this rotation of rotating element pushes fluid through flexible tubular structure. Method of lubricating an ophthalmic pump system includes: rotating a rotary member of a pump component for supplying fluid through a flexible tubular structure of the body and lubrication of one or more elements of pump component with lubricating solution located in cavity and in contact with at least part of rotating element and with at least part of flexible tubular structure.
EFFECT: using the given group of inventions enables improving lubrication between a pump of a surgical hand block and a flexible tubular structure in a surgical hand block.
