Patent number: 11666723Abstract: A nasal cannula includes a distribution conduit running along a virtual distribution path. The distribution path defines a longitudinal direction and has two branch openings. A respective supply conduit branches off from each branch opening. The distribution conduit also has two coupling openings arranged spaced apart from the branch openings. The nasal cannula has a plug via which one of the two coupling openings can be sealed as a closure opening. Another of the two coupling openings is designed as a supply opening. The plug has a flow-directing configuration with an exposed flow-directing surface. In a reference state in which the plug is closing the closure opening, the flow-directing surface is arranged in the distribution conduit in the longitudinal extension region of at least one branch opening and positioned relative to the distribution path to deflect treatment gas flowing in the distribution conduit from the supply opening along the distribution path towards at least one of the branch openings.Type: GrantFiled: September 10, 2019Date of Patent: June 6, 2023Assignee: HAMILTON MEDICAL AGInventors: Ingo Schwaiger, Sandro Walker

Patent number: 11617845Abstract: A method and apparatus for providing ventilatory assistance to a spontaneously breathing patient an error signal (56) is computed that is the difference between a function of respiratory airflow (54) over a period of time and a target value (52). Using a servo loop, air is delivered to the patient at a pressure that is a function of the error signal, the phase of the current breathing cycle, and a loop gain that varies depending on the magnitude of the error signal. The loop gain increases with the magnitude of the error signal, and the gain is greater for error signals below a ventilation target than for error signals above the ventilation target value. The target value (52) is an alveolar ventilation that takes into account the patient's physiologic dead space.Type: GrantFiled: September 19, 2019Date of Patent: April 4, 2023Inventor: David John Bassin
