Bag system for collecting and sampling a biological fluid
A bag system for the collection and sampling of a biological fluid such as blood is described. The system may include a fluid collection bag and a first tube connected on one end to a collection means and on the other end to the collecting bag. It may also include a flexible sampling bag defining an internal volume having a bottom side and an introduction side which is opposite to the bottom and has an inlet orifice. The system also has a second tube, a first end part of which is connected to the first tube and a second end part of which is inserted in the inlet orifice of the sampling bag, so as to extend inside the sampling bag over a distance of between 25% and 60% of the distance between the bottom and the introduction side of the internal volume of the sampling bag.
1. A bag system for collecting and sampling a biological fluid from a donor comprising:
a collection bag for collecting the biological fluid;
a first tube connected at a first end to a collection means and at a second end to the collection bag;
a flexible sampling bag defining an internal volume, the internal volume having a bottom side and an introduction side having an inlet orifice;
a second tube having a first end connected to the first tube and a second end inserted into the inlet orifice of the sampling bag; and
a lateral sampling device connected to the second tube outside of the sampling bag and operable to allow the collection of biological fluid samples from the sampling bag,
wherein the second end of the second tube extends into the internal volume of the sampling bag over a distance between 25% and 60% of the distance between the bottom side and the introduction side of the internal volume.
2. A bag system for collecting and sampling a biological fluid from a donor comprising:
a collection bag for collecting the biological fluid;
a first tube connected at a first end to a collection means and at a second end to the collection bag;
a flexible sampling bag defining an internal volume, the internal volume having a bottom side and an introduction side having an inlet orifice; and
a second tube having a first end connected to the first tube and a second end inserted into the inlet orifice of the sampling bag,
wherein the second end of the second tube extends into the internal volume of the sampling bag over a distance between 25% and 60% of the distance between the bottom side and the introduction side of the internal volume; and
wherein the biological fluid comprises blood or a blood component.
3. The bag system of claim 2 , further comprising the system operable to reduce the risk of embolism to the donor during donation of the blood or blood component.
4. A bag system for collecting and sampling a biological fluid from a donor comprising:
a collection bag for collecting the biological fluid;
a first tube connected at a first end to a collection means and at a second end to the collection bag;
a flexible sampling bag defining an internal volume, the internal volume having a bottom side and an introduction side having an inlet orifice;
a second tube having a first end connected to the first tube and a second end inserted into the inlet orifice of the sampling bag,
wherein the second end of the second tube extends into the internal volume of the sampling bag over a distance between 25% and 60% of the distance between the bottom side and the introduction side of the internal volume;
a satellite bag system;
at least one satellite tube connected at a first end to the satellite bag system and connected at a second end to the collecting bag; and
a lateral sampling device connected to the second tube outside of the sampling bag and operable to allow the collection of biological fluid samples from the sampling bag.
5. A bag system for collecting and sampling a biological fluid from a donor comprising:
a collection bag for collecting the biological fluid;
a first tube connected at a first end to a collection means and at a second end to the collection bag;
a flexible sampling bag defining an internal volume, the internal volume having a bottom side and an introduction side having an inlet orifice;
a second tube having a first end connected to the first tube and a second end inserted into the inlet orifice of the sampling bag,
wherein the second end of the second tube extends into the internal volume of the sampling bag over a distance between 25% and 60% of the distance between the bottom side and the introduction side of the internal volume;
a satellite bag system;
at least one satellite tube connected at a first end to the satellite bag system and connected at a second end to the collecting bag;
wherein the biological fluid comprises blood or a blood component.
6. The bag system of claim 5 , further comprising the system operable to reduce the risk of embolism to the donor during donation of the blood or blood component.
