Abstract
The present invention relates to a container (1, 10) for holding a liquid, in particular an infusion or irrigation liquid, said container having a liquid phase (6) containing the liquid and a gas phase (4), in which in the operating position a liquid opening is formed in the lower region of the container (1, 10) and the container has a gas opening. The gas opening is formed by a gas pipe (3) permanently connected to the container (1, 10) and having a first gas pipe end (12) and a second gas pipe end (13). The first gas line end (12) extends into the gas phase (4) of the vessel (1, 10) and is provided with a fastener. The second gas pipe end (13) opens to the outside of the vessel (1, 10).
Claims19
A method for forming a blood clot-based wound dressing, comprising:
- accumulating a volume of blood in a test tube with an opening sealed by an elastic stopper;
- transferring blood from the test tube to a molding space of a blood-clotting mold device, with a blood clot-support matrix within said space, said transferring comprising
- propelling a fluid into said tube through at least one first conduit that extends through the stopper between a first distal and a first proximal end within said tube and at the same time permitting blood to flow out of the tube through at least one second conduit between a second proximal end within said tube and a second distal end, and
- collecting the blood egressing out of the second distal end in said molding space;
- and
- permitting the blood to clot while in contact with said matrix to thereby obtain a wound dressing comprising a blood clot integrated with said matrix.
A method for forming a blood clot-based wound dressing, comprising transferring an amount of blood to a molding space of a blood-clotting mold device, with a blood clot-support matrix within the space, and permitting the blood to clot while in contact with said matrix to thereby obtain a wound dressing comprising a blood clot integrated with said matrix;
- wherein said transferring comprises
- accumulating a volume of blood in a test tube sealed by an elastic stopper, and
- propelling a fluid into said tube through at least one first conduit that extends through the stopper between the first conduit's first distal end its first proximal end within said tube and at the same time permitting blood to flow out of the tube through at least one second conduit between the second conduit's second proximal end within said tube and a second distal end, and
- collecting the blood egressing out of the second distal end in said molding space.
A system for forming a blood clot-based wound dressing, comprising:
- a blood-collection test tube with an elastic stopper;
- a blood-clotting mold device defining a molding space with a blood clot-support matrix within said space;
- a fluid propelling device;
- and
- a coupling device
- having a first coupling member and a second, tube-coupling member for coupling with said test tube,
- fluid conduits defined in the device that comprise at least one first fluid conduit extending between a first distal end in the first coupling member and a first proximal end at an end of a first proximal elongated element, and at least one second fluid conduit extending between a second distal end at an end of a distal elongated element and a second proximal end at an end of an elongated element,
- the first and second proximal elongated elements projecting off the device at said tube-coupling member and configured for piercing through said stopper,
- the distal elongated element being configured for piercing a wall of said molding space, and
- the first coupling member being configured for coupling to said fluid propelling device to permit said propelling device to propel fluid into said first conduit through said first distal end.
A coupling device, comprising:
- a first coupling member and a second coupling member, the first coupling member being configured for coupling with a fluid propelling device and the second coupling member being configured for coupling with a stopper-sealed test tube;
- and
- fluid conduits defined in the device that comprise
- at least one first fluid conduit extending between a first distal end in the first coupling member and a first proximal end formed at an end of a first proximal elongated element, and at least one second fluid conduit extending between a second distal end at an end of a distal elongated element and a second proximal elongated element,
- the first and second proximal elongated elements projecting off the device at said tube-coupling member and configured for piercing through the stopper of the test tube;
- the coupling of the first coupling member with said propelling device permits fluid communication between the fluid propelling device and said first distal end;
- whereby
- upon coupling of said coupling device to said propelling device and to said test tube filled with a liquid, actuation of the propelling device propels fluid into the first conduit which in turn causes the liquid to be drained out of said test tube through said second conduit;
- wherein said propelling device is a syringe;
- wherein the elongated elements have each a sharp tip for penetrating through the stopper.
A coupling device, comprising:
- a first coupling member and a second coupling member, the first coupling member being configured for coupling with a fluid propelling device and the second coupling member being configured for coupling with a stopper-sealed test tube;
- and
- fluid conduits defined in the device that comprise
- at least one first fluid conduit extending between a first distal end in the first coupling member and a first proximal end formed at an end of a first proximal elongated element, and at least one second fluid conduit extending between a second distal end at an end of a distal elongated element and a second proximal elongated element,
