  • Patent number: 7018375
    Abstract: A drug delivery device comprising a holding reservoir, a pump, a delivery reservoir and an outlet.
    Type: Grant
    Filed: June 12, 2002
    Date of Patent: March 28, 2006
    Inventor: Thomas John Berrigan
  • Patent number: 6471686
    Abstract: A drug delivery device comprising a holding reservoir, a pump, a delivery reservoir and an outlet, said holding reservoir being connected to said delivery reservoir through said pump by a connection, said pump being operable manually whereby fluid is transferred from the holding reservoir to the delivery reservoir, said delivery reservoir being connected to the outlet through a flow restriction which controls flow to the outlet, said delivery reservoir being resiliently expandable from a minimum volume to a maximum volume whereby the pressure induced on the fluid within the delivery reservoir between a first volume and a second volume provides a generally constant rate of fluid delivery where the first volume is greater than the second volume and wherein the connection between the holding reservoir and the delivery reservoir permits flow only from the holding reservoir to the delivery reservoir while the pressure within the delivery reservoir is less than a maximum pressure, said connection having a control m

  • Patent number: 6319245
    Abstract: A drug delivery means comprising a holding reservoir (11), a pumping means (16), a delivery reservoir (23) and outlet (25), said holding reservoir (11) being connected to the delivery reservoir (23) through the pump (16) where the pump (16) is operable manually to effect transfer of fluid from the holding reservoir (11) to the delivery reservoir (23), the delivery reservoir (23) being connected to the outlet (25) through a flow restriction means (27) which controls the flow to the outlet (25), the delivery reservoir being formed to be resiliently expandable to a maximum volume and wherein the connection between the holding reservoir (11) and delivery reservoir (23) prevents pressurisation of the delivery reservoir (23) substantially beyond a predetermined pressure which will be achieved on the delivery reservoir (23) obtaining its maximum volume, a control means (30) provided with the delivery reservoir to prevent further pressurisation of the delivery reservoir (23) substantially beyond the predetermined pre

  • Patent number: 5871478
    Abstract: A subcutaneous drug delivery means which comprises a holding reservoir (11), a pumping means (15), a delivery reservoir (18) and an outlet (21). The holding reservoir (11) is connected to the delivery reservoir (18) through the pump (15) which is operable manually to deliver fluid from the holding reservoir (11) to the delivery reservoir (18). The delivery reservoir (18) is resiliently expandable from a minimum volume to a maximum volume and is connected to the outlet (21) through a flow restriction means (23) which controls flow to the outlet.
