Patent number: 10213206Abstract: A device for performing a remote ischemic conditioning treatment. The device includes an inflatable cuff and a cartridge which is a source of gas for inflating the cuff. A first valve controls the flow of gas from the cartridge to the cuff so as to maintain a predetermined pressure in the cuff during an ischemic period. A second valve allows gas to escape from the cuff during a reperfusion period of the remote ischemic conditioning treatment. A controller which may be battery-powered is used to control the opening and closing of the valves. The cartridge may contain a gas, or materials which, under certain conditions, react to produce a gas. The chemical reaction may be initiated by an electrical pulse or signal from the controller.Type: GrantFiled: March 12, 2014Date of Patent: February 26, 2019Assignee: CellAegis Devices Inc.Inventors: Rocky Eugene Ganske, Raymond Cracauer, Lahav Gil

Patent number: 10210774Abstract: A method and apparatus to simulate arterial blood pressure pulses to train clinicians in the use of oscillometric blood pressure monitors is described. The apparatus comprises a bladder or blood pressure cuff placed in a rigid enclosure with a known volume. The enclosure also has an opening, with a pressure plate placed between the opening and the bladder. An actuator, such as a servo motor with an arm, is attached to the outside of the enclosure next to the opening such that the arm of the servo motor or actuator may exert a force on the pressure plate, which in turn impinges the bladder. The bladder may be connected to a pressure sensor and an oscillometric blood pressure monitor. The force exerted by the actuator may be controlled in a feedback loop by a controller connected to the actuator and the pressure sensor.Type: GrantFiled: November 17, 2016Date of Patent: February 19, 2019Assignee: Dynasthetics, LLCInventor: Joseph Orr
