Clamp, especially for a connection between a ventilator and a patient

A connection device for establishing a fluid connection between a first device and a second device, the connection device comprising:

• a first fluid guide unit being connectable with the first device;
• a second fluid guide unit being connectable with the second device;
• and
• a clamp, the clamp comprising:
• a clamping tube, the clamping tube comprising:
• a blocking fluid guide element;
• a first connecting fluid guide element;
• and
• a second connecting fluid guide element, wherein the blocking fluid guide element is fluid-tightly connected to the first connecting fluid guide element and is fluid-tightly connected to the second connecting fluid guide element;
• a clamping unit comprising two clamping components;
• and
• a locking unit configured to lock the two clamping components and to thereby hold the clamping unit in a blocking state,
• wherein the blocking fluid guide element is located between the two clamping components,
• wherein the clamping unit is configured to selectively be brought into a releasing state or into the blocking state,
• wherein with the clamping unit being in the releasing state, the blocking fluid guide element establishes a fluid connection between the first connecting fluid guide element and the second connecting fluid guide element,
• wherein with the clamping unit being in the blocking state, the two clamping components prevent a flow of fluid through the blocking fluid guide element or reduce a flow of fluid through the blocking fluid guide element by at least 80% compared to the releasing state and thereby interrupt or at least limit the fluid connection between the first connecting fluid guide element and the second connecting fluid guide element,
• wherein the first connecting fluid guide element is fluid-tightly connected to the first fluid guide unit, and
• wherein the second connecting fluid guide element is fluid-tightly connected to the second fluid guide unit.

A process comprising:

• providing a clamp for selectively releasing or blocking a fluid connection, the clamp comprising:
• a clamping unit comprising two clamping components;
• a locking unit configured to lock the two clamping components and to thereby hold the clamping unit in a blocking state;
• and
• a clamping tube, the clamping tube comprising:
• a blocking fluid guide element;
• a first connecting fluid guide element;
• and
• a second connecting fluid guide element;
• locating the blocking fluid guide element between the two clamping components;
• fluid-tightly connecting the blocking fluid guide element to the first connecting fluid guide element and to the second connecting fluid guide element;
• selectively bringing the clamping unit into a releasing state or into the blocking state;
• with the clamping unit being in the releasing state, the blocking fluid guide element establishing a fluid connection between the first connecting fluid guide element and the second connecting fluid guide element;
• and
• with the clamping unit being in the blocking state, the two clamping components preventing a flow of fluid through the blocking fluid guide element or reducing a flow of fluid through the blocking fluid guide element by at least 80% compared to the releasing state and thereby interrupting or at least limiting the fluid connection between the first connecting fluid guide element and the second connecting fluid guide element.
