    • A fibrin mixture and dispenser assembly is provided for mixing a first protein component with sterile water to form a first protein solution and for dispensing the first protein solution. The first protein solution forms a biological adhesive when intermixed with a second protein solution. The second protein solution is preferably mixed and dispensed by a similar fibrin mixture and dispenser assembly. The two fibrin mixture and dispenser assemblies can be housed within a single housing. The assembly includes a piercer and a first tubular extension having grooves for providing fluid communication between a reservoir and a mixing chamber or a vial. The reservoir is also in fluid communication with a dispensing needle through a second tubular extension. The reservoir is configured to contain water which is introduced to the mixing chamber. The mixing chamber is configured to contain the first protein component. The water mixes with the first protein component within the mixing chamber to form the first protein solution. The solution is transferred to the reservoir and is dispensed via the dispensing needle. The first and second components are preferably fibrinogen and thrombin which intermix either prior to or on the application site to form a fibrin sealant.
    • 提供纤维蛋白混合物和分配器组件用于将第一蛋白质组分与无菌水混合以形成第一蛋白质溶液并用于分配第一蛋白质溶液。 当与第二蛋白质溶液混合时,第一种蛋白质溶液形成生物粘合剂。 第二蛋白质溶液优选地通过类似的纤维蛋白混合物和分配器组件混合和分配。 两个纤维蛋白混合物和分配器组件可以容纳在单个壳体内。 组件包括穿孔器和第一管状延伸部,其具有用于在贮存器和混合室或小瓶之间提供流体连通的凹槽。 储存器还通过第二管状延伸部与分配针流体连通。 储存器构造成包含被引入混合室的水。 混合室配置成容纳第一蛋白质组分。 水与混合室内的第一蛋白质组分混合以形成第一蛋白质溶液。 将溶液转移到储存器中并通过分配针分配。 第一和第二组分优选纤维蛋白原和凝血酶,其在施用部位之前或之上混合以形成纤维蛋白密封剂。
