Patent number: 8448274Abstract: A leg support instrument is designed to be fastened, in a table fastening condition, to a longitudinal side of an operating table. The instrument comprises a first frame part provided with fastening means having a table engaging portion. The instrument also comprises a second frame part with adjustable support means fastened thereto for supporting a lower leg of a person. A first hinge having a first axis of rotation connects the first frame part to the second frame part. In the table fastening condition, different distances can be set between the table engaging portion and the first axis of rotation. The instrument comprises aligning means for aligning a position of the first axis of rotation depending on a position of a person lying on the operating table. The aligning means are designed for projecting a light beam extending in line with the first axis of rotation on the lying person.Type: GrantFiled: April 7, 2009Date of Patent: May 28, 2013Assignee: Academisch Ziekenhuis GroningenInventor: Paulus Maria Antonius Broens

Patent number: 6125293Abstract: The carbon dioxide tension in the wall of the stomach or gastrointestinal tract is determined by inserting into the stomach a semipermeable balloon filled with a saline solution. The result obtained from analyzing the carbon dioxide fraction in the saline solution is multiplied by a correction factor to obtain a stabilized measured value for the carbon dioxide fraction relating to the blood flowing through the wall of the stomach or the gastrointestinal tract, which stabilized measured value corresponds to a measured carbon dioxide fraction pertaining to a retention time of an hour or more, and multiplying the carbon dioxide tension PaCO.sub.2 in the arterial blood with a first factor F.sub.1 to obtain a first correction product, and multiplying the stabilized value of the carbon dioxide tension PiCO.sub.2 in the blood flowing through the wall of the stomach or the gastrointestinal tract by a second factor F.sub.Type: GrantFiled: January 5, 1999Date of Patent: September 26, 2000Assignee: Academisch Ziekenhuis GroningenInventor: Johannes Louis Bams
