Flexible bag for liquid, particularly a urine or blood bag, containing a sampling device

Abstract

The application relates to taking a sample of liquid contained in a flexible closed container, for example, a bag for collecting urine or blood. The problem to be resolved relates to piercing the wall of the container with a non- cutting piece, whilst obtaining a precise and clean opening for accessing the liquid and preventing any unintended flow or spill of liquid. This problem is resolved according to the present invention by a flexible bag (13, 14) for liquid, particularly a urine or blood bag which is characterised in that it contains a device (9) for taking a sample of liquid from said flexible bag. The sampling device (9) comprises a circular opening (1), arranged so that this opening is accessible from a first side of the device. The device (9) further comprises a support structure (2) on its other side, said support structure (2) comprising at least one support element (3), whose function is to distribute forces, and which is positioned at a distance from the plane of said opening (1).

Description

technical field [0001] The invention relates to the field of medical and / or biological analysis. More specifically, the present invention relates to the sampling of liquids contained in flexible closed containers, such as bags used to collect urine or blood. Background technique [0002] In order to analyze this type of fluid, for example, to perform a cytobacteriological urine test, it is first and foremost to collect a urine sample under conditions where the sample is not contaminated by the collection process. When the urine (or more generally, liquid) to be analyzed is contained in a closed collection bag that does not have a discharge line that would allow easy collection of the sample under the required aseptic conditions , then it is theoretically possible to sample with a syringe equipped with a needle. After disinfecting a suitable area on the surface of the bag, for example with alcohol wipes, the needle of the syringe is used to penetrate the wall of the bag and...

Problems solved by technology

[0003] However, this method of handling carries the risk of accidental sticking by the needle of the syringe, which is a more serious risk when urine or blood may become contaminated and thus the needle may infect the operator

In addition, by piercing the wall of the bag with the needle of the syringe, it will be easier to draw the urine sample through the second wall of the bag instead of staying inside the bag, which will not only contaminate the urine sample, but also cause urine leakage
