Patents by Inventor Lloyd Ketchum

Lloyd Ketchum has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8053248
    Abstract: A suitable container for plasma lyophilization has been designed for lyophilization (lyo-bag), storage, reconstitution and administering of blood products. A rigid support frame for use with a lyo-bag with sidewalls was designed as an external removable supportive system, which provides the necessary stability for the flexible container during lyophilization. A removable bottom wall support sheet was designed for use with any flexible container for lyophilization.
    Type: Grant
    Filed: August 12, 2005
    Date of Patent: November 8, 2011
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Irina Bakaltcheva, Donna Wilder, Peter Hmel, Anne-Marie O'Sullivan, Lloyd Ketchum
  • Patent number: 7931919
    Abstract: The invention is directed to stabilized whole-cell plasma, which retains the integrity and overall stability of the proteins and other macromolecules of the plasma. Stabilization is accomplished by the addition of glycine to plasma which allows for stabilization prior to freeze drying. Glycine, in the presence of the salt concentration in the plasma, does not recrystallize and acts as a superior stabilizer for the lyophilized plasma. The stability of the freeze dried plasma may be further improved by addition of protectants including calcium chloride, trisodium citrate, hydroxyethyl starch, ammonium sulfate and citric acid to maintain physiologic pH. Superior stability for a wide variety of plasma proteins and functions is shown. A system for the large scale preparation of sterile lyophilized plasma is also provided.
