Liquid stop
A package for a catheter is provided. The package includes a container with a first cavity and a second cavity. The cavities are configured so as to prevent liquid swelling medium stored in the container from travelling from the second cavity into the first cavity and out through an opening into the container. Thus, the position of the cavities with respect to each other allows them to function as a water-lock.
1. A catheter package comprising:
a container and an inner-tube element formed as an integral part of the container, the container containing a hydrophilic coated catheter, the hydrophilic coated catheter having a proximal end insertable into a urethra and a distal end provided with an outlet adapted to allow urine to exit the hydrophilic coated catheter, the container having a first cavity and a second cavity, with a portion of the inner-tube element extending coaxially inside of the first cavity of the container and with the second cavity formed by an inner surface of the inner-tube element, where the second cavity formed by the inner surface of the inner-tube element has a proximal opening located in the first cavity and a distal opening located at a distal end of the container, with the proximal end of the hydrophilic coated catheter extending out of the proximal opening of the second cavity and with the distal end of the hydrophilic coated catheter extending out of the distal opening of the second cavity;
a closure coupled to the container; and
a liquid contained in the first cavity of the container;
wherein the closure is coupled to the container to completely enclose the hydrophilic coated catheter within the package;
wherein the hydrophilic coated catheter is stored in the package in a pre-wetted condition where a hydrophilic coating of the hydrophilic coated catheter is wetted by the liquid contained in the first cavity of the container;
wherein the inner-tube element and the first cavity are configured to prevent the liquid contained in the first cavity of the container from exiting the opening located at a distal end of the container.
2. The catheter package of claim 1 , wherein a distance D is provided between an inner surface of the first cavity and the inner surface of the inner-tube element, and the distance D is selected to prevent the liquid from travelling from the first cavity into the second cavity when the catheter package is in a horizontal orientation.
3. The catheter package of claim 1 , wherein the container is in a vertical position with the inner-tube element located distal of the proximal end of the hydrophilic coated catheter, and the liquid is in contact with the proximal end of the hydrophilic coated catheter and not in contact with the inner-tube element.
4. The catheter package of claim 1 , wherein the container is in an inverted vertical position with the proximal end of the hydrophilic coated catheter located distal of the inner-tube element, and the liquid contained in the first cavity of the container is prevented from entering the inner-tube element.
5. A catheter package comprising:
a hydrophilic coated catheter having a proximal end insertable into a urethra;
a container and an inner-tube element formed as an integral part of the container, the container having a first cavity and a second cavity, with a portion of the inner-tube element extending inside of the first cavity of the container and with the second cavity formed by an inside of the inner-tube element, where the second cavity formed by the inside of the inner-tube element has a proximal opening located in the first cavity and a distal opening located at a distal end of the container, with the hydrophilic coated catheter extending through the inner-tube element and the proximal end of the hydrophilic coated catheter extending out of the proximal opening of the second cavity and into the first cavity;
a closure coupled to the container; and
a liquid contained in the first cavity of the container;
wherein the closure is coupled to the container to completely enclose the hydrophilic coated catheter within the package;
wherein the hydrophilic coated catheter is stored in the package in a pre-wetted condition where a hydrophilic coating of the hydrophilic coated catheter is wetted by the liquid contained in the first cavity of the container;
wherein the inner-tube element and the first cavity are configured to prevent the liquid contained in the first cavity of the container from exiting the opening located at a distal end of the container.
6. A catheter package comprising:
a hydrophilic coated catheter having a proximal end insertable into a urethra;
a container and an inner-tube element formed as an integral part of the container, the container having a first cavity and a second cavity, with a portion of the inner-tube element extending inside of the first cavity of the container and with the second cavity formed by an inside of the inner-tube element, where the second cavity formed by the inside of the inner-tube element has a proximal opening located in the first cavity and a distal opening located at a distal end of the container, with the hydrophilic coated catheter extending through the inner-tube element and the proximal end of the hydrophilic coated catheter extending out of the proximal opening of the second cavity and into the first cavity;
a closure coupled to the container; and
a liquid contained in the first cavity of the container;
wherein the closure is coupled to the container to completely enclose the hydrophilic coated catheter within the package;
wherein the hydrophilic coated catheter is stored in the package in a pre-wetted condition where a hydrophilic coating of the hydrophilic coated catheter is wetted by the liquid contained in the first cavity of the container;
wherein, when the closure is removed from the container, wherein the inner-tube element and the first cavity are configured to prevent the liquid contained in the first cavity of the container from exiting the opening located at a distal end of the container.
