Patent number: 8707792Abstract: A drug delivery device (10) includes a pressurized reservoir (14) in communication with a flow path to an outlet (12). The flow path includes two normally-closed valves (16, 18) and a flow restriction (18). A pressure measurement arrangement (22) measures a differential fluid pressure between two points (24, 26) along the flow path which span at least part of the flow restriction (18), one of the points being between the valves (16, 18). A controller (28) selectively opens the valves (16, 18) to deliver a defined quantity of the liquid medicament to the outlet (12).Type: GrantFiled: August 25, 2011Date of Patent: April 29, 2014Assignee: Nilimedix Ltd.Inventor: Avraham Shekalim

Patent number: 7377907Abstract: A portable insulin delivery device that supplies insulin in a pre-pressurized chamber, passes the insulin through a pressure-dropping labyrinth to a flow control valve. The valve is activated by a piezoelectric actuator. This allows for precise insulin delivery. An electronic package provides for programming of basal rates and bolus. A pressure sensor relays data concerning normal operation and pressure changes that indicate problems. The processor, keypad, displays power source, fluid pressure sensor and fluid flow control actuator are housed in a base unit. A removable cartridge unit houses the pre-pressurized fluid reservoir, flow path labyrinth, and flow control valve.Type: GrantFiled: March 5, 2004Date of Patent: May 27, 2008Assignee: Nilimedix Ltd.Inventor: Avraham Shekalim

Publication number: 20070250007Abstract: A drug delivery device includes a drug reservoir which is pressurized by the pressure of air compressed during the course of insertion of a reservoir container itself. Also provided is a safety cut-off valve arrangement in which a two-valve flow control system is further supplemented by a safety cut-off valve which closes the flow path whenever the electronics unit required for operation of the device is not properly installed.Type: ApplicationFiled: April 23, 2007Publication date: October 25, 2007Applicant: NILIMEDIX LTD.Inventor: Avraham Shekalim
