A method is disclosed for preparing at least one compound having biological properties from blood. The method is carried out inside closed tubes under subatmospheric pressure, so as to reduce or prevent bacterial contamination of the compound caused by handling same. The method includes, inter alia, the repetition of the following steps any desired number of times: connecting a second vacuum container to a blood sampling device in turn connected to a first container that contains blood separated into fractions; waiting until the desired fraction(s) have been transferred, and withdrawing the second container. Various second containers containing different compounds for different medical uses may be obtained, including for biological therapies. The steps can be carried out in a closed system, without opening the containers, or the first container may be opened before the blood sampling device is introduced.

L'invention concerne un procédé de préparation d'au moins un composé à propriétés biologiques à partir de sang, ledit procédé s'exécutant dans des cylindres fermés à pression inférieure à la pression atmosphérique, afin de réduire ou de prévenir la contamination bactérienne du composé par manipulation. Ce procédé consiste, entre autres, à répéter le nombre de fois que l'on souhaite les étapes suivantes: relier un second conteneur à vide à un dispositif d'extraction relié à son tour à un premier conteneur qui contient du sang séparé en fractions, à attendre un moment que la ou les fraction(s) désirée(s) soit transférée(s) et à retirer le second conteneur, divers seconds conteneurs avec différents composés destinés à différentes applications médicales y compris des thérapies biologiques pouvant être obtenus. Ces étapes peuvent être exécutées dans un système fermé, sans déboucher les conteneurs, ou le premier conteneur peut être ouvert avant l'introduction du dispositif d'extraction.
