Abstract
Le sang des règles contenant de la prothrombine, mais aussi tous les autres facteurs de la coagulation à l'exception du fibrinogène, est incoagulable. L'activation de la voie endogène par la mise en jeu des facteurs contact doit être suffisante pour transformer la prothrombine en thrombine agissant ainsi sur le fibrinogène (composant ajouté au sein du bioréacteur) pour le transformer en fibrine. Il est légitime de penser que la quantité de thrombine générée soit suffisante pour engendrer la coagulation du sang, mais on peut imaginer un ajout supplémentaire de thrombine (au sein du bioréacteur) qui jouerait un rôle catalytique supplémentaire. Le protocole opératoire consiste à rajouter du fibrinogène à une concentration de l'ordre de 1 gramme par litre (de sang) et de la thrombine à environ 10 UI (Unités internationales) par litre pour activer la transformation du fibrinogène en fibrine.The blood of the menses containing prothrombin, but also all the other factors of coagulation except fibrinogen, is incoagulable. Activation of the endogenous pathway through contact factors must be sufficient to convert prothrombin to thrombin, thereby acting on fibrinogen (a component added within the bioreactor) to transform it into fibrin. It is legitimate to think that the amount of thrombin generated is sufficient to cause blood coagulation, but one can imagine an additional addition of thrombin (within the bioreactor) that would play an additional catalytic role. The operating procedure consists of adding fibrinogen at a concentration of the order of 1 gram per liter (of blood) and thrombin to about 10 IU (International Units) per liter to activate the conversion of fibrinogen to fibrin.

Personnes impliquéesInvolved persons
Dans le cadre de cette demande de brevet, les personnes impliquées ont les statuts suivants : • Inventeur : Professeur François Forestier • Co Inventeur : Steve EisenhutIn the context of this patent application, the persons involved have the following status: • Inventor: Professor François Forestier • Inventor Co: Steve Eisenhut
Description de l’objet de la demande de brevetDescription of the subject of the patent application
Dans le cadre d'un tampon hygiénique innovant, il nous est apparu évident qu'on pouvait mettre à profit des connaissances au sujet de la coagulation pour concevoir un nouveau dispositif sur la base d'un bioréacteur.In the context of an innovative hygienic tampon, it became clear to us that knowledge about coagulation could be used to design a new device based on a bioreactor.
Dans ce contexte, le bioréacteur offre la possibilité qu'ont des substances de transformer un milieu liquide en un milieu gélifié. Concernant la coagulation du sang des règles, cette transformation sol-gel est due à la thrombine qui transforme une molécule soluble (le fibrinogène) en molécule insoluble (la fibrine).In this context, the bioreactor offers the possibility of substances transforming a liquid medium into a gelled medium. Concerning the blood coagulation of the rules, this sol-gel transformation is due to thrombin which transforms a soluble molecule (fibrinogen) into an insoluble molecule (fibrin).
Plus précisément, au sein de cette demande de brevet, notre bioréacteur est un ensemble biologique constitué d'un substrat (fibrinogène) et d'une enzyme (thrombine) permettant la transformation d'un milieu biologique (le sang des règles dans notre cas) d'un état à un autre (notamment sol-gel).More specifically, within this patent application, our bioreactor is a biological set consisting of a substrate (fibrinogen) and an enzyme (thrombin) for the transformation of a biological medium (the blood of the rules in our case) from one state to another (especially sol-gel).
Le sang des règles a effectivement comme particularité de ne pas contenir du fibrinogène. C'est pourquoi notre dispositif contient une protéine (le fibrinogène) et une enzyme (la thrombine). Dès lors notre dispositif, intégré au sein même du concept développé dans le nouveau brevet « Tampon Hygiénique 2.0 », permet une protection des menstruations totalement nouvelle puisque cette nouveauté intègre deux brevets, celui d'une structure totalement innovante, et la possibilité pour la première fois de rendre ce sang coagulable, améliorant ainsi le confort des protections féminines au court des menstruations.The blood of rulers actually has the peculiarity of not containing fibrinogen. This is why our device contains a protein (fibrinogen) and an enzyme (thrombin). Therefore our device, integrated within the concept developed in the new patent "Tampon Hygienic 2.0", allows a completely new menstruation protection since this novelty includes two patents, that of a completely innovative structure, and the possibility for the first time. to make this blood coagulable, thus improving the comfort of feminine protection during menstruation.
Le sang des règles contenant de la prothrombine, mais aussi tous les autres facteurs de la coagulation à l'exception du fibrinogène, est incoagulable. L'activation de la voie endogène par la mise en jeu des facteurs contact doit être suffisante pour transformer la prothrombine en thrombine agissant ainsi sur le fibrinogène (composant ajouté au sein du bioréacteur) pour le transformer en fibrine. Il est légitime de penser que la quantité de thrombine générée soit suffisante pour engendrer la coagulation du sang, mais on peut imaginer un ajout supplémentaire de thrombine (au sein du bioréacteur) qui jouerait un rôle catalytique supplémentaire. Le protocole opératoire consiste à rajouter du fibrinogène à une concentration de l'ordre de 1 gramme par litre (de sang) et de la thrombine à environ 10 Ul (Unités Internationales) par litre pour activer la transformation du fibrinogène en fibrine.The blood of the menses containing prothrombin, but also all the other factors of coagulation except fibrinogen, is incoagulable. Activation of the endogenous pathway through contact factors must be sufficient to convert prothrombin to thrombin, thereby acting on fibrinogen (a component added within the bioreactor) to transform it into fibrin. It is legitimate to think that the amount of thrombin generated is sufficient to cause blood coagulation, but one can imagine an additional addition of thrombin (within the bioreactor) that would play an additional catalytic role. The operating procedure consists of adding fibrinogen at a concentration of the order of 1 gram per liter (of blood) and thrombin to about 10 IU (International Units) per liter to activate the conversion of fibrinogen to fibrin.
