Publication number: 20090036873Abstract: A device for stimulating the healing of a wound comprises a separating means having a fluid inlet and a gas outlet. The separating means may constitute a collecting container for collecting fluid pumped from the wound. A pump for applying negative pressure comprises pump head and a drive unit. The pump head is connected to the gas outlet of the separating means, and the pump head is detachably attached to the drive unit, so that in use the fluid inlet of the separating means is connected to a wound cover, e.g. via a conduit.Type: ApplicationFiled: February 1, 2007Publication date: February 5, 2009Applicant: COLOPLAST A/SInventors: Brian Nielsen, Jesper Mads Bartroff Frederiksen, Truels Sterm Larsen, Erik Lund Jepsen, Niels Hvid, Klaus Budig

Publication number: 20090030383Abstract: A suction system for removal of fluids from a surface, e.g. a wound site, the system comprising a cover (1) attachable to a circumference of the surface to form an enclosed suction space sealed from ambient space. The system further comprises a pump (4) in fluid communication with the enclosure via a tube (2) to provide a pressure difference between a suction pressure in the enclosure and an air pressure of an ambient space. To provide an improvement over the known systems and to facilitate pressure measurement, the system comprises flushing means (11) to clean the tube.Type: ApplicationFiled: February 1, 2007Publication date: January 29, 2009Inventors: Truels Sterm Larsen, Erik Lund Jepsen, Niels Hvid

Publication number: 20090005746Abstract: A suction system for removal of exudate from a wound comprises a wound cover which is attachable to a wound circumference of a living being thereby to form an enclosure, and a pump in fluid communication with the enclosure to provide a pressure difference between a negative pressure in the enclosure and an air pressure of an ambient space. A deflectable member is arranged such with respect to the enclosure that the pressure difference may cause deflection of the deflectable member, and a pressure sensing device is located outside the enclosure and arranged to provide a signal in response to the pressure or the deflection of the deflectable member. The deflectable member forms an essentially air tight barrier between the sensor and the enclosure.Type: ApplicationFiled: February 1, 2007Publication date: January 1, 2009Inventors: Brian Nielsen, Jesper Mads Bartroff Frederiksen, Truels Sterm Larsen, Erik Lund Jepsen, Niels Hvid, Klaus Budig

Patent number: 7005010Abstract: A system for processing a workpiece includes an inner chamber pivotably supported within an outer chamber. The inner chamber has an opening to allow liquid to drain out. A motor pivots the inner chamber to bring the opening at or below the level of liquid in the inner chamber. As the inner chamber turns, liquid drains out. Workpieces within the inner chamber are supported on a holder or a rotor, which may be fixed or rotating. Multi processes may be performed within the inner chamber, reducing the need to move the workpieces between various apparatus and reducing risk of contamination.Type: GrantFiled: September 4, 2003Date of Patent: February 28, 2006Assignee: Semitool, Inc.Inventors: Eric Bergman, Dana Scranton, Erik Lund, Worm Lund

Patent number: 6806194Abstract: A system for processing a workpiece includes a head attached to a head lifter. A workpiece is supported in the head between an upper rotor and a lower rotor. A base has a bowl for containing a liquid. The head is movable by the head lifter from a first position vertically above the bowl, to a second position where the workpiece is at least partially positioned in the bowl. The bowl has a contour section with a sidewall having a radius of curvature which increases adjacent to a drain outlet in the bowl, to help rapid draining of liquid from the bowl. The head has a load position, where the rotors are spaced apart by a first amount, and a process position, where the rotors are engaged and sealed against each other. For rapid evacuation of fluid, the head also has a fast drain position, where the rotors are moved apart sufficiently to create an annular drain gap.Type: GrantFiled: April 14, 2003Date of Patent: October 19, 2004Assignee: Semitool. Inc.Inventors: Paul Z. Wirth, Steven L. Peace, Erik Lund

Publication number: 20040023276Abstract: The present invention features nucleic acids and polypeptides encoding LXR-Ligand Induced I (LXRLI1). Treatment of human cells with acetylpodocarpic dimer, a LXR-agonist compound, results in an increase in LXRLI1 gene expression. The cDNA sequence of LXRLI1 is provided by SEQ ID NO 1. The amino acid sequence for LXRLI1 is provided by SEQ ID NO 2. The present invention also defines an LXR-ligand induced gene and provides methods for using gene expression profiles of this set of LXR regulated genes to measure LXR activity in a subject, to diagnose a disease or disorder involving LXR activity, to screen for compounds that change the activity of LXR and to classify LXR ligands.Type: ApplicationFiled: May 2, 2003Publication date: February 5, 2004Inventors: Teresa R. Ward, Mao Mao, Peter S. Linsley, Erik Lund
