Patent number: 8534283Abstract: An application for a PEEP valve includes a filter media in the air flow between a patient interface and exit vent(s). The patient interface is connected to a patient airway system and the exit vents exhaust exhalation gasses into the atmosphere. The filter prevents or reduces the passage of microbes from the patient's exhalation gasses into the atmosphere. The PEEP valve provides positive gas pressure to a patient's lungs, requiring a predetermined exhalation gas pressure to be exceeded before releasing exhalation gasses into the atmosphere.Type: GrantFiled: July 19, 2010Date of Patent: September 17, 2013Assignee: Mercury Enterprises, Inc.Inventors: George E.

Patent number: 8418689Abstract: Apparatus for use during open system diving to support underwater human respiration. In accordance with various embodiments, an air supply provides a supply of air along a supply conduit. A regulator is adapted for engagement with a diver's mouth to receive air from the supply during an inhale cycle and to direct a mixture of water and exhaust air away from the diver along an exhaust conduit during an exhale cycle. An air/water separator separates the exhaust air from the water in said mixture and directs the separated exhaust air through an exhaust air port. In some embodiments, a one-way stop valve is provided within the air/water separator to prevent back flow. In further embodiments, a bubble diffuser emits the exhaust air as a fine mist of bubbles into the surrounding water.Type: GrantFiled: May 17, 2010Date of Patent: April 16, 2013Assignee: Davenport Innovations, Inc.Inventor: Steven Roy Davenport

Patent number: 7175611Abstract: The present invention relates to medical devices that are inserted or implanted into patients and that have antimicrobial coatings that release free radicals into the vicinity of the device. These devices may have coatings that alter their rate of flow release or elution release of an antibacterial agent from a coating on the device upon external stimulation. The coating should therefore be responsive to external control such as by heating, external RF stimulus, sonic control, visible or ultraviolet light exposure and the like. By having control of the release rate, and in some structures without invasion of the patient by mechanical means in addition to the device itself, the release rate can be in response to need at the implant site. The class of compounds to be released are free radical generating or initiating compounds, or compounds that release free radicals upon immersion or stimulation, the free radicals acting as the antimicrobial agent.Type: GrantFiled: June 5, 2002Date of Patent: February 13, 2007Inventor: Mark Alan Mitchnick

Patent number: 7153290Abstract: A flange attaching section has a flange supporting section and a movable section, and the movable section can approach the flange supporting section and separate therefrom due to rotational moving. Even if a flange section of a barrel of a syringe has various thickness, the flange section is easily attached between the flange supporting section and the movable section, and although the attachment is easy, the flange section comes in pressure contact with the flange supporting section in the attached state. Even if, therefore, the flange section of the barrel of the syringe has various thickness, a syringe pump, in which moving of the barrel of the syringe during infusion is prevented securely and the infusion is executed at an accurate speed, is provided.Type: GrantFiled: July 30, 2003Date of Patent: December 26, 2006Assignee: Atom Medical CorporationInventors: Keisuke Wakabayashi, Tatsuhiko Seki, Kazuo Matsubara
