SELF-CENTERING ROLLER CONFIGURATION FOR FLUID-TRANSFERING MEDICAL EQUIPMENT

摘要

Case 771112 SELF-CENTERING ROLLER CONFIGURATION FOR FLUID-TRANSFERING MEDICAL EQUIPMENT Rollers for moving blood or other fluids through resilient tubing are improved by a curved surface configuration which will automatically center the tubing longitudinally along the roller and create a differential surface velocity when in operation in order to urge the tubing to the center of the roller and maintain its location there. This improved configuration enhances the ease of use of blood donor tube strippers and the like, enhances their relibility, and makes them more durable products which are less susceptible to maladjustment both when manufactured and when in use.
