Container containing reference solution
View Patent ↗The present disclosure provides a container containing reference solution for clinical chemistry, whereby the container includes a closure part-covered outlet at which reference solution can be removed by puncturing with a puncturing element. The disclosure further provides a wick that is soaked with the reference solution and arranged in the container to extend from the outlet and such that a majority of its length extends into an interior space of the container.
1. A container containing reference solution for clinical chemistry, including:
an outlet for extracting reference solution by puncturing with a puncturing element of a puncturing device;
a closure part covering the outlet;
a wick having a length, the wick being positioned in the container and extending from the outlet such that a majority of the length extends into an interior space of the container to contact reference solution contained in the interior space; and
a rigid molded wall that forms a stop that resists pressure exerted on the container by the puncturing device during extraction of a sample of the reference solution;
wherein the rigid molded wall forms a channel extending between the interior space and the outlet, the wick being secured to the channel.
2. A container according to claim 1 , wherein the wall surrounds the wick and carries the closure part.
3. A container according to claim 1 , wherein the wall is configured to withstand a press-against force of at least 3 N when the puncturing device engages the container during extraction of the sample without reference solution being forced from the outlet.
4. A container according to claim 1 , wherein the closure part is connected to the container by a pre-determined breakage zone.
5. A container according to claim 1 , further including a pressure compensation channel that is closed by the closure part and extends into the interior space adjacent to the wick.
6. A container according to claim 1 , wherein the wick includes a fiber bundle.
7. A container according to claim 1 , wherein a majority of the length of the wick touches against the channel.
8. A container according to claim 1 , wherein the closure part is removable and the wick is positioned in the container to project from the container, when the closure part is removed, by a distance that is smaller than a width of the wick.
9. A container according to claim 1 , wherein the wick includes fibers that are distributed over a cross-section of the wick.
10. A container according to claim 1 , wherein the wick immerses into the reference solution, when the outlet faces upwardly.
11. A container according to claim 1 , wherein one end of the wick is positioned at the outlet.
12. A container containing reference solution for clinical chemistry, including:
a wick disposed within an interior space of the container in contact with the reference solution contained in the interior space;
a container wall configured to be pierced by a puncturing device upon extraction of the reference solution; and
a ring-shaped disc inside the container that surrounds the wick and supports the container wall thereby forming a stop that resists pressure exerted on the container wall by the puncturing device during extraction of the reference solution.
13. A container containing reference solution for clinical chemistry, including:
an outlet for extracting reference solution by puncturing with a puncturing element of a puncturing device;
a closure part covering the outlet;
a wick having a length, the wick being positioned in the container and extending from the outlet; and
a container wall that forms a stop that, without deforming, resists pressure exerted on the container by the puncturing device during extraction of a sample of the reference solution;
wherein the container wall forms a channel extending between the interior space and the outlet, a majority of the length of the wick being in contact with the channel.
14. A container containing reference solution for clinical chemistry, including:
an outlet for extracting reference solution by puncturing with a puncturing element of a puncturing device;
a closure part covering the outlet;
a wick having a length, the wick being positioned in the container and extending from the outlet such that a majority of the length extends into an interior space of the container to contact reference solution contained in the interior space;
a container wall that forms a stop configured to resist pressure exerted on the container by the puncturing device during extraction of a sample of the reference solution; and
a foil base connected to the container wall and spanning an opening of the container wall.
15. A container containing reference solution for clinical chemistry, including:
an outlet for extracting reference solution by puncturing with a puncturing element of a puncturing device;
a closure part covering the outlet;
a wick having a length, the wick being positioned in the container and extending from the outlet; and
a container wall configured to withstand a press-against force of at least 3 N when the puncturing device engages the container during extraction of the sample without reference solution being forced from the outlet;
wherein the container wall forms a channel extending between the interior space and the outlet, a majority of the length of the wick being in contact with the channel.
