Benefits of technology
"The invention provides methods, systems, and apparatuses for manufacturing, storing, and administering freeze-dried materials, such as single donor units of freeze-dried human plasma. The invention includes a container with two chambers separated by a sealing wall. One chamber holds the freeze-dried material, while the other chamber holds a reconstituting liquid. A valve assembly in the sealing wall can be manipulated to open a region of the sealing wall and establish fluid flow communication between the two chambers. The reconstitutable material can then be reconstituted within the container and administered to a recipient. The invention also includes an outer skirt that can be removed to expose the valve assembly for manipulation. The invention allows for flexible storage and administration of freeze-dried materials."
Problems solved by technology
For instance, initial treatment of a severely wounded person in combat situations can often mean the difference between life and death.

Embodiment Construction
[0050]Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structures. While the preferred embodiment has been described, the details may be changed without departing from the invention, which is defined by the claims.
I. Device for Storing and Reconstituting Freeze-Dried Plasma
[0051]FIGS. 1 and 2 show a device 10 for storing and administering a freeze-dried material. The device 10 comprises a flexible bag having a first collapsible chamber 12 and a second collapsible chamber 14.
[0052]The first chamber 12, also referred to as the dry chamber, contains an aliquot of a freeze-dried material 16. The nature and type of freeze-dried material 16 can vary. In the illustrated embodiment, the freeze-dried material comprises human plasma, and the aliquot is a single donor unit of human plasma.
[0053]The second chamber 14,...

A freeze-dried material is stored in a first chamber of a container along with a reconstituting liquid for the freeze-dried material, which is stored in a second chamber of the container. A sealing wall within the container forms a barrier between the first chamber and the second chamber preventing contact between the freeze-dried material and the reconstituting liquid. At least one valve assembly in the sealing wall selectively opens a region of the sealing wall to establish fluid flow communication between the first and second chambers, allowing the freeze dried material to be reconstituted. The reconstituted freeze-dried material can be administered from the same container to a recipient.
Description
RELATED APPLICATIONS[0001]This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 11 / 725,352, filed Mar. 19, 2007, and entitled Apparatus and Methods for Making, Storing, and Administering Freeze-Dried Materials Such as Freeze-Dried Plasma, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to methods, systems, and apparatuses for manufacturing, storing and administering freeze-dried materials, such as single donor units of freeze-dried human plasma.BACKGROUND OF THE INVENTION[0003]First aid is critical for the survival of a person that has suffered a serious injury, such as a trauma victim. For instance, initial treatment of a severely wounded person in combat situations can often mean the difference between life and death. While it is necessary to treat the wounds and stop the bleeding of the person, it is also important to ensure that the person's body is capable of properly functioning. Thus, it i...
