Publication number: 20100292648Abstract: An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. A device includes a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid.Type: ApplicationFiled: July 28, 2010Publication date: November 18, 2010Inventors: Alexander G. Lastovich, James K. Fentress, Julia Griggs, Ronald J. Pettis, Diane Sutter, Frank E. Martin, M. Ishaq Haider

Patent number: 7678079Abstract: A system and method for a patch-like, self-contained substance infusion device which provides one or more substantially hidden patient needles which can be placed in fluid communication with a fluid reservoir subassembly that includes a rigid bladder portion used in conjunction with a non-distensible bladder film, such as a metallized film. Simple removal of an interlock allows a disk, or Belleville spring assembly to apply an essentially even and constant pressure to the contents of the fluid reservoir assembly, and allows the device to then be attached to a skin surface via an adhesive contact surface. A push button activation assembly is provided which can then be used to release and seat one or more spring-loaded patient needles into the skin surface, and establish a fluid communication path between the patient needles and the pressurized fluid reservoir contents thereby delivering an infusion into the skin.Type: GrantFiled: April 25, 2007Date of Patent: March 16, 2010Assignee: Becton, Dickinson and CompanyInventors: Charles D. Shermer, Kenneth G. Powell, Alexander G. Lastovich, P. Spencer Kinsey, Chad C. Smutney, John M. Polidoro, Ed Browka, Carl R. Sahi, James K. Fentress, David S. Chapin, Daniel Stipe, Jeff M.

Patent number: 7214221Abstract: A fluid delivery device for delivering a substance to a patient by way of infusion delivers the preparation at a rate of flow which varies in steps from a substantially constant higher rate, to a stepped-down substantially constant lower rate or rates. The delivery device includes one or more reservoirs, and one or more Belleville springs for applying generally constant pressures to the substance contained in the reservoirs. Each reservoir will have a different constant pressure applied in a mid-range of operation. The reservoirs can be interconnected to each other and to an infusion device in a number of arrangements, including various manifolds and flow restrictors, such that the rate of flow is controlled in steps in accordance with the pressures applied by the springs of the plurality of reservoirs.Type: GrantFiled: March 26, 2003Date of Patent: May 8, 2007Assignee: Becton, Dickinson and CompanyInventors: James K.

At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid. The dermal-access member extends at least 1 mm from the protrusion. A mechanism drives the device against the skin at a calculated speed of about 6 m/s to about 18 m/s.Type: GrantFiled: September 27, 2004Date of Patent: August 1, 2006Assignee: Becton Dickinson and CompanyInventors: Alexander G.
