Patent number: 7573026Abstract: A correction for pileup of measurements made by a nuclear detector is applied by selecting the energy of the first signal in a pileup, ignoring the remaining signals in the pileup, and correcting the count rate by a factor related to the total pulse widths within a unit time interval. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: GrantFiled: June 14, 2007Date of Patent: August 11, 2009Assignee: Baker Hughes IncorporatedInventors: Philip L.

Patent number: 5944700Abstract: A pen needle of the present invention includes an extender that is rotatably attached to a hub on the pen needle to set the pen needle to a desired injection length. The extender is rotated into multiple predefined positions using a shield that is removably mounted on the pen needle. Each predefined position for the extender corresponds to a predetermined injection length for the pen needle such that the extender covers a section of the pen needle not being used for the injection. After the shield has been used to rotate the extender into one of the predefined positions the shield is removed from the pen needle to expose the distal point of the pen needle so that the injection can be performed.Type: GrantFiled: September 26, 1997Date of Patent: August 31, 1999Assignee: Becton, Dickinson and CompanyInventors: Tuan V. Nguyen, Michael A. Dibiasi

Patent number: 5941857Abstract: A disposable pen needle assembly is provided that includes a snap lock feature that provides a user with a simple method of detaching and attaching the pen needle to the medication delivery pen. In addition, the pen needle assembly includes a multi-use shield that initially shields the distal end of the pen needle prior to use and then both shields the proximal end of the needle and locks the used needle in its outer cover prior to disposal.Type: GrantFiled: September 12, 1997Date of Patent: August 24, 1999Assignee: Becton Dickinson and CompanyInventors: Tuan V. Nguyen, Michael A. Dibiasi

Patent number: 5931817Abstract: A pen needle having a cylindrical hub including a distal section that is received in a needle holder and a proximal section having threads that mate with a pair of lugs in an adaptor mounted on a medication delivery pen. The distal end of the pen needle includes a plurality of splines that mate with splines in the needle holder to prevent the pen needle from rotating within the needle holder and aid in threading the pen needle onto the adaptor. The pen needle is fully received in the needle holder to shield the proximal point of the pen needle and can only be removed from the needle holder by using the adaptor or a cartridge retainer having the proper pair of lugs thereon.Type: GrantFiled: September 12, 1997Date of Patent: August 3, 1999Assignee: Becton Dickinson and CompanyInventors: Tuan V. Nguyen, Michael A. DiBiasi, Robert E. West

Patent number: 5873462Abstract: A pen needle dispenser having a cover rotatably mounted on a circular shaped container having a plurality of cavities, with each cavity dimensioned to receive a pen needle assembly with or without shields. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused shielded pen needle and thereby permits the pen needle to be mounted on a medication delivery pen. After use the used unshielded pen needle is returned to and locked in the cavity. Then, the cover is rotated until the slot is aligned with another cavity containing the next unused shielded pen needle to be used during the next injection. The pen needle dispenser prevents the cover from rotating the slot back to cavities containing used pen needles.Type: GrantFiled: September 12, 1997Date of Patent: February 23, 1999Assignee: Becton Dickinson and CompanyInventors: Tuan V. Nguyen, Michael A. DiBiasi, Robert E. West

Patent number: 5829589Abstract: A pen needle magazine dispenser designed to be received and carried in a cap of a medication delivery pen. The dispenser having a cover rotatably mounted on a circular shaped container with a plurality of cavities, wherein each cavity is dimensioned to receive one pen needle. The pen needle being of a type that is forced fit into an adaptor on the pen using threads on the pen needle and corresponding threads in the cavity. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused pen needle and thereby permit the pen needle to be mounted on the pen. After use the used pen needle is returned to the cavity and the cover is rotated until the slot is aligned with another cavity containing the next unused pen needle to be used during the next injection.Type: GrantFiled: September 12, 1997Date of Patent: November 3, 1998Assignee: Becton Dickinson and CompanyInventors: Tuan V.
