Abstract: Connector for a fluid transport line of a medical device, comprising: a first body having a first access port for a fluid, a second access port for a fluid, and a first fluid path extending in the first body and directly connecting, for fluid transport, the first access port and second access port, at least a second body, mountable to the first body, having at least a third access port for a fluid, the second body being movable with respect to the first body at least between: a main operating position in which the first fluid path is interrupted and in which a second fluid path is defined and enabled, for fluid transport, from the first access port to the third access port, and an auxiliary operating position in which the first fluid path is enabled and in which the second fluid path is interrupted.

Abstract: A method is provided for measuring the local hydraulic permeability, Lpi, of a sub-group of hollow fibres of a bundle of hollow fibres mounted in a tubular casing. The method comprises a step of placing the casing containing the bundle in a vertical position, the lateral opening of the casing being disposed toward the bottom, and sealing the lower end of the casing. A graduated, calibrated tube is applied in a vertical position over a portion of the upper cut surface of the bundle to form a sealed connection there between. A liquid is passed through the lateral opening of the casing at a defined flow rate, and the time required for the liquid to pass from a first graduation to a second graduation of the tube is measured.
