Publication number: 20220273888Abstract: A syringe assembly includes a syringe barrel (12) having a proximal end and a distal end, a needle hub (20) supporting the needle and coupled to the distal end of the syringe barrel (12). A moveable shield (36) is included for sliding from a first position where the needle is exposed a first length, a second position where the needle is exposed a second length less than said first length, and a third position covering a distal end of the needle. A locking mechanism (48, 86) is included to retain the shield in the second position while enabling the shield to slide to the third position, and to lock the shield in the third position to prevent re-use of the syringe.Type: ApplicationFiled: July 29, 2020Publication date: September 1, 2022Applicant: Becton,Dickinson and CompanyInventors: John KNIGHT, Jeffrey REED, Scott TOWNSEND, Patrick MCCALLUM

Publication number: 20220088842Abstract: An adhesive patch is secured to an infusion set, patch pump or other on-body medical device by an overmolding process during manufacture of the medical device, or during manufacture of a portion of the medical device, without the need for a separate adhesive. This provides a more secure connection between the patch and the medical device, and reduces the required number of adhesive layers from two (skin attachment side and device attachment side) to one (skin attachment side only), thereby simplifying the design and manufacture of the patch.Type: ApplicationFiled: November 18, 2021Publication date: March 24, 2022Applicant: Becton, Dickinson and CompanyInventors: Jeffrey Reed, John Knight, Scott Townsend

Patent number: 7425709Abstract: A modular ion source design relies on relatively short modular core ALS components, which can be coupled together to form a longer ALS while maintaining an acceptable tolerance of the anode-cathode gap. Many of the modular components may be designed to have common characteristics so as to allow use of these components in ion sources of varying sizes. A flexible anode can adapt to inconsistencies in the ion source body and module joints to hold a uniform anode-cathode gap along the length of the ALS. A clamp configuration fixes the cooling tube to the ion source body, thereby avoiding heat-introduced warping to the source body during manufacturing.Type: GrantFiled: July 21, 2004Date of Patent: September 16, 2008Assignee: Veeco Instruments, Inc.Inventors: Daniel E.

Patent number: 7342236Abstract: An ion source is cooled using a cooling plate that is separate and independent of the anode. The cooling plate forms a coolant cavity through which a fluid coolant (e.g., liquid or gas) can flow to cool the anode. In such configurations, the magnet may be thermally protected by the cooling plate. A thermally conductive material in a thermal transfer interface component can enhance the cooling capacity of the cooling plate. Furthermore, the separation of the cooling plate and the anode allows the cooling plate and cooling lines to be electrically isolated from the high voltage of the anode (e.g., using a thermally conductive, electrically insulating material). Combining these structures into an anode subassembly and magnet subassembly can also facilitate assembly and maintenance of the ion source, particularly as the anode is free of coolant lines, which can present some difficulty during maintenance.Type: GrantFiled: February 18, 2005Date of Patent: March 11, 2008Assignee: Veeco Instruments, Inc.Inventors: David Matthew Burtner, Scott A. Townsend, Daniel E. Siegfried, Viacheslav V. Zhurin

Patent number: 6984942Abstract: An ion source design and manufacturing techniques allows longitudinal cathode expansion along the length of the anode layer source (ALS). Cathode covers are used to secure the cathode plates to the source body assembly of an ion source. The cathode covers allow the cathode plate to expand along the longitudinal axis of the ion source, thereby relieving the stress introduced by differential thermal expansion. In addition, the cathode cover configuration allows for less expensive cathode plates, including modular cathode plates. Such plates can be adjusted relative to the cathode-cathode gap to prolong the life of a given cathode plate and maintain source performance requirements. A cathode plate in a linear section of an ion source has symmetrical edges and can, therefore, be flipped over to exchange the first (worn) cathode edge with the second (unworn) cathode edge.Type: GrantFiled: July 21, 2004Date of Patent: January 10, 2006Assignee: Veeco Instruments, Inc.Inventors: Daniel E.

Patent number: 6919690Abstract: A modular ion source design relies on relatively short modular anode layer source (ALS) components, which can be coupled together to form a longer ALS. For long ion sources, these shorter modular components allow for easier manufacturing and further result in a final assembly having better precision (e.g., a uniform gap dimensions along the longitudinal axis of the ion source). Modular components may be designed to have common characteristics so as to allow use of these components in ion sources of varying sizes. A modular gas distribution system uniformly distributes a working gas to the ionization region of the module ion source. For each gas distribution module, gas distribution channels and baffles are laid out relative to the module joints to prevent gas leakage. Furthermore, gas manifolds and supply channels are used to bridge module joints while uniformly distributing the working gas to the ALS.Type: GrantFiled: July 21, 2004Date of Patent: July 19, 2005Assignee: Veeco Instruments, Inc.Inventors: Daniel E.
