Clamp for closing flexible tubes
The patent US12044335B2 describes a clamp designed for closing flexible tubes, featuring an anvil and a hammer mechanism. The anvil includes a passage for the tube and a slot that accommodates the hammer, which can slide between two positions. In the first position, the passage remains unobstructed, while in the second position, the hammer occludes the passage, effectively preventing fluid flow through the tube. The anvil is equipped with opposing racks, each containing detents that interact with the hammer's fingers to secure it in either position. Additionally, the design allows for user access to release the hammer from the detents, and it is noted that the clamp can function even when cryogenically frozen.
Further claims detail the structural features of the clamp, including ramps within the anvil that assist in guiding the hammer's movement between positions. The hammer can be ratcheted along a defined rack to secure its position, and a notch in the anvil allows for easy release of the hammer. The hammer is designed to be removable and can be formed separately from the anvil, enhancing the clamp's versatility. Overall, the invention provides a reliable mechanism for securely closing flexible tubes, with user-friendly features for operation and maintenance.
