Patent number: 10124094Abstract: Devices and to methods for thoracic drainage for a patient having an air fistula. A vacuum is produced in the pleural cavity of the patient by means of a suction device. In order to adjust the vacuum on the basis of objective criteria, a suitable size measure for the air fistula is determined and the vacuum produced by the suction device is controlled according to said size measure. An adaptive algorithm includes: (a) determining a first value of a size measure for the air fistula; (b) changing the vacuum by a first difference value; (c) determining a second value of the size measure after a first waiting period; (d) changing the vacuum by a second difference value having the opposite sign if the second measure is greater than the first measure; (e) repeating steps (a) to (d) after a second waiting period.Type: GrantFiled: May 24, 2012Date of Patent: November 13, 2018Assignee: MEDELA HOLDING AGInventors: Albert Linder, Hilmar Ehlert, Martin Walti

Patent number: 10076592Abstract: A system for aspirating fluids from a body by means of negative pressure has: a drainage line for removing the fluid from the body, a fluid collection container connected to the drainage line and used to collect the aspirated fluid, a pump by which the negative pressure used to aspirate the fluid is generated in the drainage line, and an auxiliary line whose end near the body is in fluidic communication with an end, near the body, of the drainage line. In the system, an approximately closed circuit is present or can be generated which interconnects this pump, the auxiliary line, the drainage line and the fluid collection container and through which air or a liquid can be pumped, wherein the auxiliary line is usable for flushing the drainage line. This system prevents and removes obstructions in the drainage line and also permits a relatively accurate measurement of the negative pressure in the body cavity.Type: GrantFiled: June 14, 2012Date of Patent: September 18, 2018Assignee: MEDELA HOLDING AGInventor: Hilmar Ehlert

Patent number: 9839726Abstract: A device for thoracic drainage comprises a container connector for a secretion collection container (3), which can be connected to the pleural cavity of a patient, and a venting device (10) for releasing air from the secretion collection container in passive operation. In order to keep the counterpressure as low as possible during the air release and thus make it easier to force air out of the pleural cavity (1) of a patient, the venting device has a controllable vent valve (12). For this purpose, a control device (7) determines the pressure in the secretion collection container by reading out a pressure sensor (11) and controls the valve to release air from the secretion collection container when the determined pressure exceeds a threshold value. The device can optionally also be operated actively by way of a vacuum connector (25). An ancillary line (2?) permits monitoring of the drainage line (2).Type: GrantFiled: July 5, 2012Date of Patent: December 12, 2017Assignee: MEDELA HOLDING AGInventor: Hilmar Ehlert

Publication number: 20170007749Abstract: A thorax drainage device for aspirating fluids from a pleural cavity of a patient using underpressure has a fluid collection container for collecting the aspirated fluids and a drainage tube for connecting the fluid collection container to the pleural cavity of the patient. The fluid collection container is connectable to a vacuum source, in order to generate an underpressure in the fluid collection container. The thorax drainage device has an adjustable mechanism for attenuating pressure differences during the respiration of the patient, this mechanism being adjustable independently of a suction capacity of the vacuum source. This device permits a gradual expansion of the lung without risk of injury and thus prepares the lung for the completion of the drainage.Type: ApplicationFiled: January 27, 2015Publication date: January 12, 2017Applicant: MEDELA HOLDING AGInventors: Martin Walti, Hilmar Ehlert

Patent number: 9486561Abstract: A suction apparatus for aspirating a fluid from a human or animal body by negative pressure comprises a drainage connection for a drainage line in order to remove the fluid from the body. A vacuum source generates a negative pressure at the drainage connection. A fluid connection container collects the sucked-up fluid. The drainage line can be flushed with air by an auxiliary connection and an auxiliary line connected to the latter. In order to reduce the entraining of pathogens, a sterilizing cell is provided. The supplied air is treated in the latter in such a manner that pathogens contained in the air are modified and thereby rendered harmless.Type: GrantFiled: July 11, 2013Date of Patent: November 8, 2016Assignee: Medela Holding AGInventors: Martin Walti, Hilmar Ehlert
