Abstract: The invention relates to a secure system for the perfusion of a body liquid, enabling a final control of compatibility of a treatment with the patient and/or the medical situation previously diagnosed by a doctor, in a simple, efficient and energy-saving manner. To this end, the system includes a fluidic circuit of a perfusion having a perfusion catheter, a perfusion tubing and a container for the determined perfusion product to be perfused to a patient. The system is also configured to take a body liquid sample from a patient and to analyze and compare the body liquid sample to the determined perfusion product so as to control the flow of the perfusion product.

Abstract: The invention relates to a device (200) for taking a sample of a body fluid, such as blood, to be incorporated into a fluid circuit of a perfusion (100) of a patient who has a perfusion catheter (104), said device having a tubular structure (202) for connecting to the fluid circuit of the perfusion, provided with a zone for intubation, during use, of a sampling channel (300) comprising a distal end (301); and a means (203) for holding, during use, in the tubular structure, the part of the sampling channel (300) comprising a distal end (301) in such a way that the distal end (301) is oriented towards the perfusion catheter (104), in the direction of flow (F1) of the perfusion product (102), from a perfusion product reservoir (101) towards the perfusion catheter (104).

Abstract: The invention relates to a disposable device comprising all of the reagents necessary for the detection of one or more particles of interest, and which can be incorporated in a detection system including simple means for the automatic management of fluids. For this purpose, the invention relates to a disposable device for the detection of one or more particles of interest present in a liquid sample, said device comprising a substrate provided with: a chamber for capturing the particle(s) of interest to be detected; a fluid channel connecting, upstream, the capture chamber to a buffer solution container, a liquid sample injection means and a container of labelling probes that can be secured to the particle(s) of interest to be detected; and a fluid channel connecting, downstream, the capture chamber to a container for the recovery of liquids which, during use, can flow from the capture chamber.
