Summary for Patent: 10,624,814
Title: | Container for a solution of human plasma proteins and method for obtaining thereof |
Abstract: | A container for a solution of human plasma proteins has a primary inner bag made up of a first multilayer polymer film with two outer layers of polyethylene (PE) and an intermediate layer of ethylene vinyl alcohol (EVOH) copolymer, and a secondary outer bag made up of a second multilayer film with layers of polyethylene terephthalate (PET)-silicon oxides (SiOx), oriented polyamide (OPA), polypropylene (PP)-silicon oxides (SiOx) and polypropylene (PP), referred to as multilayer PP-SiOx. |

Application Number: | 15/611,582 |
Patent Claims: | 1. A container for a solution of human plasma proteins, comprising: a) a primary inner bag comprising sheets of a first multilayer polymer film, wherein the first multilayer
polymer film comprises two outer layers of polyethylene (PE) and an intermediate layer of ethylene vinyl alcohol (EVOH) copolymer, and b) a secondary outer bag comprising a second multilayer polymer film, wherein the second multilayer polymer film
comprises layers of polyethylene terephthalate (PET)-silicon oxides (SiOx), oriented polyamide (OPA), polypropylene (PP)-silicon oxides (SiOx) and polypropylene (PP), wherein the solution of human plasma proteins is contained within the primary inner
bag, and wherein a weight loss of the container is significantly reduced.
2. The container according to claim 1, wherein the primary inner bag comprises an inlet cap structure, wherein the inlet cap structure is configured to be closed hermetically, either reversibly or irreversibly by welding. 3. The container according to claim 2, wherein the welding is produced by ultrasound. 4. The container according claim 2, wherein an inlet of the inlet cap structure and the sheets of the primary inner bag are welded together by heat contact to hermetically close the inlet irreversibly. 5. The container according to claim 1, wherein the primary inner bag comprises an inlet comprising two small wings to facilitate the heating and welding of said inlet to the sheets of the primary inner bag. 6. The container according to claim 1, wherein the human plasma proteins obtained from human plasma and contained in the primary inner bag comprise albumin, .alpha.-1-antitrypsin, von Willebrand factor, coagulation factors such as factor VII, factor VIII and factor IX, immunoglobulins, plasminogen, plasmin, antithrombin III, fibrinogen, fibrin, thrombin or combinations thereof. 7. The container according to claim 6, wherein the human plasma proteins comprise immunoglobulins. 8. The container according to claim 1, wherein the secondary outer bag is designed in peelable form. 9. A method for preparing a container according to claim 1 for human plasma proteins, the method comprising the following steps: a) sterile filtering of a solution of human plasma proteins through a 0.2 .mu.m membrane to obtain a sterile solution; b) filling the primary inner bag by lifting the cap of said inner bag in a sterile environment and introducing the sterile solution obtained at step a); c) inserting an inlet cap into the inlet of the primary inner bag in a sterile environment, and providing a hermetic closure therebetween by welding; d) inserting the primary bag obtained at step c) into the secondary outer bag and welding said secondary bag. 10. The method according to claim 9, wherein the human plasma proteins obtained from human plasma and contained in the primary inner bag comprise albumin, .alpha.-1-antitrypsin, von Willebrand factor, coagulation factors such as factor VII, factor VIII and factor IX, immunoglobulins, plasminogen, plasmin, antithrombin III, fibrinogen, fibrin, thrombin or combinations thereof. 11. The method according to claim 10, wherein the human plasma proteins comprise immunoglobulins. 12. The method according to claim 9, wherein the method comprises an additional incubation step for 21 days at 25.+-.2.degree. C. |
