Pinch Valve Isolating Urinary Drainage Tubes from Encrustation

The patent removes the valve from the urine flow path entirely. Instead of placing the valve in-line where it contacts urine, the invention uses a external compression mechanism that applies pressure to the catheter tube from the outside, isolating the valve components from urine and eliminating encrustation at connector points.

The patent introduces an external compression mechanism as an intermediary between the control system and the urine flow. The valve components remain outside the urine path, mediating flow control through external tube compression rather than direct contact with urine, thereby preventing encrustation.

The patent incorporates a feedback mechanism where the compression force applied to the tube provides information about flow status. The system can detect changes in compression requirements or flow characteristics that indicate blockages, allowing early warning before critical situations occur.

The patent implements periodic compression cycles rather than continuous open drainage. The valve compresses the tube periodically to control flow, and these periodic actions create observable patterns that can indicate when blockages are developing, improving detection capability.

The patent designs the valve to operate automatically or with minimal user input. The system self-regulates urine flow through automated compression mechanisms, eliminating the need for patients to manually operate complex valve controls, thereby making it accessible to patients with limited dexterity or cognitive impairment.

The patent replaces manual mechanical operation with automated control mechanisms. Instead of requiring patients to manually adjust mechanical valves, the system uses automated sensors, actuators, and control algorithms to manage drainage, reducing the physical and cognitive demands on the patient.
