Patents by Inventor Glen Henry Graham

Glen Henry Graham 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).

  • Blend of thermoplastic polymers including block radial polymers of the butadiene-styrene type
    Patent number: 4117035
    Abstract: Radial block copolymers are mechanically combined with additional polymeric materials to form plastic compositions having a high degree of clarity so that they can be substituted for polyvinylchloride plastic compositions in the fabrication of such devices as intravenous and blood tubing, containers for intravenous solutions and blood fractions, functional parts of intravenous administration equipment such as sight and drip chambers, needle adapters and miscellaneous assemblies for contact with intravenous fluids. The compounds of this invention can also be utilized for catherization, bodily drainage systems, and as pharmaceutical closures, resealable injection sites and syringe plunger tips.
    Type: Grant
    Filed: April 18, 1977
    Date of Patent: September 26, 1978
    Assignee: Abbott Laboratories
    Inventors: Edward Lawrence Hillier, Glen Henry Graham, Warren Evan Eichelberger
  • Blend of thermoelastic polymers with block radial polymers used as pharmaceutical sealing and resealing materials
    Patent number: 4048255
    Abstract: Radial block copolymers are blended with additional polymeric materials to form rubber-like plastic compositions having high elastic and reseal properties so that they can be utilized as a rubber replacement in the fabrication of resealable injecton sites in intravenous administration equipment and stoppers for containers where resealability after puncture is also a desirable property.
