Abstract

Cette invention concerne une méthode permettant d'écarter des risques de transfusion sanguine incompatible, caractérisée en ce que les corps des patients devant recevoir une transfusion sanguine sont repérés par des touches numérotées et que les poches de sang sont fermées ,puis ouvertes au moyen des seules touches numérotées correspondantes. L'invention concerne également les touches à utiliser conjointement avec cette méthode. Selon cette méthode, il est facile de modifier les numéros commandant l'ouverture au moyen d'un dispositif relativement simple, les risques de confusion entre patients et poches de sang pouvant être évités facilement et à peu de frais.
