Abstract
The present disclosure relates to clamps for controlling the flow of liquid through a fluid circuit. More particularly, the present disclosure relates to flow control clamps that can be substantially irreversibly secured in a closed position, thereby discouraging reopening of the flow path of the tube.
Claims14
A flow control clamp comprising:
- a flexible body comprising a central portion and a distal end, first and second legs extending from said central portion, said legs disposed relative to each other in a general facing relationship;
- said body including a pair of apertures for receiving flexible tubing therethrough wherein one of said apertures is disposed in said central portion and the other of said apertures is disposed in at least one of said legs;
- wherein said legs are movable from a first open spaced apart position to a second closed irreversibly locked position;
- a first and second locking mechanisms associated with each of said first and second legs, wherein said first locking mechanism is located at said distal end and said second locking mechanism is located between said first locking mechanism and said central portion.

A fluid processing set comprising:
- a container adapted for receiving biological fluid from a donor;
- a donor access device;
- a tubing segment defining a flow path that is in flow communication with said container and said access device;
- a flow control clamp associated with said tubing segment, said clamp comprising;
- a flexible body comprising a central portion and a distal end, first and second legs extending from said central portion, said legs disposed relative to each other in a general facing relationship and are movable from a first open spaced apart position to a second closed irreversibly locked position;
- said body including a pair of apertures for receiving said tubing segment therethrough wherein one of said apertures is disposed in said central portion and the other of said apertures is disposed in at least one of said legs;
- a first and second locking mechanisms associated with each of said first and second legs, wherein said first locking mechanism is positioned at said distal end and said second locking mechanism is positioned between said first locking mechanism and said central portion;
- at least one tube contacting member carried by one of said legs for clamping said tubing segment when said legs are in the irreversibly locked position.
