Patent number: 8525666Abstract: Systems and methods are provided for monitoring use of handwashing agents to determine compliance with hand hygiene guidelines. A handwashing agent is provided with a detectable, volatile compound, such as odors, which is then rubbed onto a subject's hands using the subject's handwashing technique. After the handwashing event, the subject's hand is then exposed to an detector (such as a badge), which includes a sensor capable of detecting the volatile compound, and an indicator that communicates detection of the volatile compound, indicating use of the handwashing agent and hand hygiene compliance.Type: GrantFiled: June 9, 2008Date of Patent: September 3, 2013Assignee: University of Florida Research Foundation, Inc.Inventors: Richard J.

Publication number: 20130172840Abstract: Embodiments of the invention provide methods and devices for improved drainage systems and tubing. In one embodiment, a context-sensitive flow interrupter is provided that inhibits or facilitates flow of fluid when engaged with a mating holder. In another embodiment, outflow is optimized through control of the pressure in gas pockets in a tube, drainage tube or assembly. In one such embodiment, gas pockets are vented to inhibit excessive back-pressure or suction on an organ, vessel or cavity being drained. In another such embodiment, loops in the tubes are avoided by using a mechanical template in the form of a groove or peg assembly to thread the slack in the drainage tube to generate a monotonic gradient. In another embodiment, such as for active drainage systems, a bypass channel is provided that allows an applied vacuum to go around an obstruction created by the collection of fluid in an undrained dependent loop.Type: ApplicationFiled: September 8, 2011Publication date: July 4, 2013Applicant: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INCORPORATEDInventors: Samsun Lampotang, Nikolaus Gravenstein, Wilhelm K.

Publication number: 20060150970Abstract: An apparatus and method for titrating the oxygen content delivered to a patient via an open delivery system and reduce fire risk. The apparatus may include a nasal cannula or face mask and an anesthesia machine having an air flowmeter. The cannula may be in fluid connection with one or more gas outlets on the anesthesia machine. The cannula may provide a user-adjustable reduced O2 content gas flow to the patient. By providing an O2 gas mixture having a lower concentration of O2, the present invention significantly mitigates the risk of surgical fires. The apparatus may also include an anesthesia machine having an electronic flowmeter, either alone or in conjunction with the cannula, for maintaining oxygen saturation at a selected level. The apparatus may also include an anesthesia machine having an additional operating mode for use with an open delivery system.Type: ApplicationFiled: July 15, 2005Publication date: July 13, 2006Applicant: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Samsun Lampotang, Nikolaus Gravenstein

Publication number: 20060060199Abstract: A self-inflating resuscitation system formed from a self-inflating resuscitation bag and an exhalation indicator. In particular, the self-inflating resuscitation bag provides an exhalation indicator, which may be an audio or visual indicator, or both. The exhalation indicator enables a caregiver to more accurately determine whether a patient is being ventilated, unlike prior art self-inflating resuscitation bags, and helps to detect esophageal intubation in intubated patients or gastric trapping of gas in non-intubated patients undergoing positive pressure ventilation. In general, the device may be interposed between any source of positive pressure ventilation and any airway device to monitor exhalation as an indicator of adequacy of ventilation.Type: ApplicationFiled: September 23, 2005Publication date: March 23, 2006Applicant: University of FloridaInventors: Samsun Lampotang, Nikolaus Gravenstein

Publication number: 20050205098Abstract: An apparatus for delivering an O2 comprising gas mixture by nasal cannula or face mask to a patient includes at least one jet pump having an inlet for receiving a high pressure O2 rich flow and an outlet for emitting a reduced O2 content flow as compared to the O2 rich flow at its inlet. The jet pump includes at least one air entrainment aperture for entraining room air and provides the reduced O2 content gas flow at its outlet, thus providing O2 dilution. A nasal cannula or face mask is in fluid connection with the outlet of the jet pump. The nasal cannula or face mask includes a fluid conduit terminating at a pair of apertured nostril outlet prongs or face facemask, respectively, for providing the reduced O2 content gas flow to the patient.Type: ApplicationFiled: March 18, 2005Publication date: September 22, 2005Inventors: Samsun Lampotang, Nikolaus Gravenstein

Publication number: 20040102783Abstract: A motorized drill is mounted in the handle of a Kerrison Rongeur System utilized by a surgeon to perform surgical procedures on a patient, includes mechanism for moving the rotating drill toward the fixed upstanding foot mounted at the remote end of the pistol-shaped handle for removing bone which is located between the upstanding foot and the drill bit. In another embodiment, the drill is removably fixed in the handle and the foot moves relative to the drill bit. In either embodiment a trigger operated by the surgeon actuates the foot/drill and the trigger is biased to maximize the space between the foot and the drill bit. The foot shape and dimension can be modified for perfecting given surgical procedures. In one embodiment the drill motor releasing mechanism includes a pinion gear and rack performing the additional function of releasing the motor locked in position in the handle.Type: ApplicationFiled: November 27, 2002Publication date: May 27, 2004Inventors: Chester E.
