Patent number: 10780221Abstract: Aspects of the invention are related to a method and a system for administrating an infusion liquid pulse. The system includes a tubing system having an inlet connected to an external reservoir adapted to contain infusion fluids and an outlet connected to a catheter. The tubing system includes a check valve proximate to the inlet and an anti-siphon valve proximate to the outlet. The system further includes an automatic pulse flow generation device. The automatic pulse flow generation device includes an internal reservoir and a bidirectional pump configured to pump infusion fluid from the external reservoir to the internal reservoir and further pump an infusion fluid pulse from the internal reservoir to be injected by the catheter, the infusion liquid pulse has a volume of at least 2 ml and a velocity of at least 5 ml/min.Type: GrantFiled: September 6, 2018Date of Patent: September 22, 2020Assignee: Medical Flow Systems Ltd.Inventor: 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
