Patent number: 7666164Abstract: A safety shield system for a needle cannula of a pen needle injector or similar device, wherein the safety shield may be retracted from a first position enclosing the needle to a second position exposing the needle for injection. The safety shield system permits retraction of the safety shield during use, but extends the shield enclosing the needle in a locked position following use. The shield system is utilized with a pen needle injector having a double ended needle cannula mounted in a hub received on the open end of the pen needle injector. The assembly is disposed of by removing the assembly and needle cannula hub and storing the assembly in the cup-shaped cap enclosing the exposed end of the needle cannula within the cap. The cap includes internal radial ribs preventing retraction of the shield prior to removing the cap preventing inadvertently piercing the cap during assembly.Type: GrantFiled: December 7, 2004Date of Patent: February 23, 2010Assignee: Becton, Dickinson and CompanyInventors: Lucio Giambattista, David E.

Patent number: 7604999Abstract: A system and method for identifying a biological sample associated with a container is disclosed. A universally unique identifier is associated with each container. In one or more embodiments, the identifier comprises one or more markings having a specular reflectance which differs from the specular reflectance of the outer surface of the container adjacent the markings. A detection apparatus detects the differences in specular reflectance light to identify the identifier associated with the container. The identifier is associated with certain information regarding the container and biological sample. From that point forward, any information about the contents of the container may be retrieved by searching on its container ID. Because the container ID is assured by its manufacturer to be universally unique, the container and sample may move from one organization to another under the same identifier, and information about the contents of the container may be shared by querying on its container ID.Type: GrantFiled: December 20, 2004Date of Patent: October 20, 2009Assignee: Becton, Dickinson and CompanyInventors: Pierre Bierre, Sreedhar Payavala

Patent number: 7022128Abstract: The present device and method includes a handle, a blade connected to the handle, and a guard slidably mounted partially within the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an exposed guard radius is provided at the distal end of the handle to allow improved handle control and blade orientation. The exposed guard radius is positioned to allow the user to firmly grip a large distal handle portion which is molded as a single piece with the blade holder, preventing unwanted blade or handle movement due to guard mechanism tolerances. A leaf spring and detent is provided to fix the guard in the extended and retracted position, and provide slight resistance during movement between each position. Additionally, an antitravel mechanism is incorporated in the guard to prevent accidental retraction from the fully extended position.Type: GrantFiled: April 22, 2003Date of Patent: April 4, 2006Assignee: Becton, Dickinson and CompanyInventors: Michael J. Morawski, Dana M. Cote, Patrick T. Thrailkill, David S. Seebauer, Mohan Rajasekaran

Patent number: 7021463Abstract: The present invention is a mechanical contrivance integrated into the closure of a sharps collector. It is intended to allow for the safe removal and disposal of a used pen needle from a pen syringe device. The pen syringe, with the used pen needle attached, is inserted into the specially designed port of the present invention. The pen syringe is then rotated counterclockwise about its longitudinal axis. The pen needle itself is constrained by at least one tooth, which only allows the pen needle one degree of freedom (linear displacement along its longitudinal axis). These conditions cause the pen needle to be unthreaded from the pen syringe, such that when the pen syringe is withdrawn from the port, a tang then blocks the pen needle from being withdrawn with the pen syringe, and the used pen needle falls into the sharps collector without the use of a secondary operation.Type: GrantFiled: September 6, 2002Date of Patent: April 4, 2006Assignee: Becton, Dickinson and CompanyInventor: Vu Phan

Patent number: 6890759Abstract: A system and method for identifying a biological sample associated with a container is disclosed. A universally unique-identifier is associated with each container. In one or more embodiments, the identifier comprises one or more markings having a specular reflectance which differs from the specular reflectance of the outer surface of the container adjacent the markings. A detection apparatus detects the differences in specularly reflected light to identify the identifier associated with the container. The identifier is associated with certain information regarding the container and biological sample. From that point forward, any information about the contents of the container may be retrieved by searching on its container ID. Because the container ID is assured by its manufacturer to be universally-unique, the container and sample may move from one organization to another under the same identifier, and information about the contents of the container may be shared by querying on its container ID.Type: GrantFiled: December 30, 1998Date of Patent: May 10, 2005Assignee: Becton, Dickinson and CompanyInventors: Pierre Bierre, Sreedhar Payavala
