Patent number: 9572931Abstract: A device, system and method for self-administration of a bolus dosage of a treatment fluid are disclosed. A device according to embodiments of the present invention may comprise a housing comprising an external lever operable by a user, an internal lever, for applying pressure to a compression spring, which in turn may press a piston to pressurize treatment fluid contained in an internal reservoir, in a high flow rate, through a small diameter catheter, into a patient body. A system according to some embodiment may comprise a device having an external reservoir connected to an inlet thereof, and a catheter connected to an outlet thereof. A method according to some embodiments may comprise actuating levers of the device, compressing a partially loaded compression spring contained in a spring cage, and pressurizing fluid contained in an internal reservoir of the device to be released through an outlet of the device.Type: GrantFiled: June 26, 2013Date of Patent: February 21, 2017Assignee: AMBU A/SInventor: Ofer Shay

Publication number: 20130123703Abstract: A device, system and method are disclosed for providing infused medication in a continuous pulse flow at a defined volume and frequency while maintaining a stable and accurate average flow rate, in order to provide improved nerve bathing and thus continuous pain blockage. The system may comprise an external reservoir, such as an infusion bag, and a pulsed flow generation device for generating a controlled pulse of fluid received from the external reservoir and retained in an internal reservoir such as a disposable syringe. One method according to an embodiment of the present invention may comprise receiving a fluid medication, such as an anesthetic substance, from an external reservoir, containing the fluid in an internal reservoir, and when the volume of fluid reaches a certain predefined value, releasing at least one pulse of fluid to create nerve bathing at a treated area.Type: ApplicationFiled: July 21, 2011Publication date: May 16, 2013Inventor: Ofer Shay

Patent number: 8381762Abstract: The invention relates to the metering of fluids at low flow rates. More particularly, the invention provides a flow regulator for flows as low as about ½ ml per hour, provided with locking means for any set value within its range. The flow regulator comprises: an inner non-revolving core element, an outer housing, having a hollow base section and being revolvably supported co-axially with the core element, first and second chambers disposed between the core element and the outer housing, each chamber having an inlet and an outlet, the outlet of the first chamber and the inlet of the second chamber being connected by a flow restriction path, a diaphragm separating the two chambers and sealing an inlet to a discharge tube when pressure in the first chamber is higher than pressure in the second chamber, and a circular spring placed in the secondary chamber below the diaphragm and around the discharge tube.Type: GrantFiled: January 21, 2008Date of Patent: February 26, 2013Assignee: MFS Medical Flow Systems Ltd.Inventor: Ofer Shay
