Bag system for collecting and sampling a biological fluid

摘要

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.
