SYSTEMS AND METHODS FOR CONTROLLING ARTICLES OF MEDICAL PURPOSE Russian patent published in 2020 - IPC A61M1/00 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to two versions of a medical system for treating tissues and a medical device for controlling circulation. In the first version, the System comprises a container comprising an outer wall surrounding an inner volume for tissue retention; and tissue filter structure. System comprises a circulation control device containing the first disc having the first holes passing through it. Device has a second disc having second holes, passing through it. Device includes the third disc having at least one third hole passing through it. First disc, second disc and third disc are functionally connected. Installation of the third disc in the first position sets the first subset of the first holes into the position of hydraulic connection with the first subset of the second holes. Installation of the third disc in the second position establishes the second subset of the first holes in the position of hydraulic connection with the second subset of the second holes. Installation of the third disc in the third position establishes the third subset of the first holes into the position of hydraulic connection with the third subset of the second holes. In the second version, the system comprises a container comprising an outer wall surrounding an inner volume for retaining tissues and a tissue filter structure. Device comprises a first disc having first holes extending therethrough and a second disc having second openings extending therethrough. First disc and second disc are functionally connected. Installation of the first disc in the first position establishes the first subset of the first holes into the position of hydraulic connection with the first subset of the second holes. Installation of the first disc in the second position establishes the second subset of the first holes into the position of hydraulic connection with the second subset of the second holes. Installation of the first disc in the third position establishes the third subset of the first holes into the position of hydraulic connection with the third subset of the second holes.

EFFECT: group of inventions provides evaluating the state of each individual tube at multiple time points throughout the operation.
