Methods, devices, systems and kits for preparing compositions for care and repair of varicose veins
The present disclosure relates to a container for the production of a foamed sclerosant composition, to kits and systems including such a container, to methods for preparing a foamed sclerosant composition using such containers, and to a foamed sclerosant compositions obtainable by such methods. In an aspect, the container comprises a container body and a mixing element disposed in the container body, such that a foaming space is defined in an interior of the container body between the sidewalls and the mixing element. The mixing element may be configured to be operatively coupled with a rotating actuator without the actuator reaching the foaming space.
1. A method for preparing and injecting a foamed sclerosant composition, the method comprising:
obtaining an assembly for the production of a foamed sclerosant composition, the assembly comprising:
a sterilized container disposed inside a sterilized packaging, the sterilized container including a container body having an interior defined by one or more sidewalls extending between a top and a bottom of the container body, and
a sterilized mixing element disposed in the sterilized packaging inside the container body, wherein the sterilized mixing element is a disc comprising a central opening in which a magnetic element is placed, the magnetic element being fixed to the disc, the sterilized mixing element being free from physical attachment to any other part, a foaming space being formed in an interior of the container body between the one or more sidewalls and at least a portion of the sterilized mixing element,
wherein the sterilized mixing element is configured to be magnetically coupled with a rotating actuator located outside the interior of the container body when the sterilized container is removed from the sterilized packaging, wherein the actuator is a magnetic stirrer,
wherein the sterilized container is configured for the introduction of a liquid sclerosant composition in the foaming space, and
wherein the bottom of the container body is configured to be positioned on the magnetic stirrer such that the magnetic stirrer when running causes a rotating magnetic field thereby dragging along the magnetic element of the disc and setting the disc into rotation, removing the sterilized container containing the sterilized mixing element from the sterilized packaging;
introducing a liquid sclerosant composition into the foaming space,
positioning the container body onto a magnetic stirrer,
running the rotating actuator magnetic stirrer at a varying speed to rotate the mixing element until the foamed sclerosant composition has been obtained,
aspirating the foamed sclerosant composition from the container using a syringe; and
injecting the aspirated foamed sclerosant composition into a patient using the syringe.
2. The method according to claim 1 , wherein the disc has a circumference and comprises teeth around the circumference.
3. The method according to claim 1 , further comprising a valve configured for the introduction of a liquid sclerosant composition the valve arranged to open towards the interior of the container body.
4. The method according to claim 1 , wherein the sterilized container includes a valve for introduction of a physiological gas.
5. The method according to claim 4 , wherein the sterilized container includes a first valve configured for the introduction of a liquid sclerosant composition the valve arranged to open towards the interior of the container body, the assembly further comprising a second valve for introduction of a physiological gas, wherein the second valve for the introduction of a physiological gas is the same as the first valve for the introduction of the liquid sclerosant agent.
6. The method according to claim 1 , wherein the container body further comprises an exit for extraction of the foamed sclerosant composition.
7. The method according to claim 6 , wherein the exit for extraction of the foamed sclerosant composition is a tearable portion of the container body.
8. The method according to claim 6 , wherein the exit is arranged at or near the bottom of the container body.
9. The method according to claim 1 , wherein the assembly further comprising comprises a lid to close off the top of the container body.
10. The method according to claim 1 , wherein a lid is integrally formed with the container body.
11. The method according to claim 1 , wherein the running the magnetic stirrer comprises running the magnetic stirrer at a speed of rotation between 60 and 1,800 RPM.
12. The method according to claim 1 , further comprising introducing a mixture of physiological gases into the interior of the container body before running the magnetic stirrer.
13. The method according to claim 3 , wherein the valve is a one-way valve arranged to open towards the interior of the container body.
14. The method according to claim 1 , wherein the foaming spaced contains atmospheric air during the preparation of the foamed sclerosant composition.
15. The method according to claim 1 , wherein the introducing a liquid sclerosant composition into the foaming space includes using an introducer defining a first channel for introducing of a physiological gas into the interior of the container body, and a second channel for evacuating a gas out of the interior of the container body.
16. The method according to claim 1 , wherein the liquid sclerosant composition comprises distilled water or a saline.
17. The method according to claim 1 , wherein introducing the liquid sclerosant composition into the foaming space includes squeezing a drug container containing the liquid sclerosant composition.
