  • Publication number: 20070068499
    Abstract: A position sensor is disclosed having a transducer formed by a Hall-effect device and permanent magnet secured within a housing on either side of a low permeability gap. A target secured to an active member, such as an EGR valve plunger moves within the gap. The target has a flux modulating property that varies with position along a direction of travel. In one embodiment, the reluctance of the target varies with position. Variable reluctance is achieved in some embodiments by varying the cross section of the target with position. In some embodiments, a second target having substantially constant reluctance secures to the active member and moves within a gap defined by a second transducer. The output of the second transducer is used to normalize the output of the first transducer and compensate for anomalies such as drift and movement other than in the direction of travel of the active member.

  • Publication number: 20070068502
    Abstract: A volume restrictor can be provided for a pneumatic paintball gun to reduce the volume of compressed gas available within a compressed gas storage area for a firing operation of the paintball gun. In one embodiment, the volume restrictor includes a body having a forward end and a rearward end. A forward sealing member can be arranged on the forward end to seal around a bolt of the paintball gun. A rearward sealing member can be arranged on the rearward end of the body to seal against a rearward endwall of the compressed gas storage area. By placing the volume restrictor within the compressed gas storage area of the paintball gun, the volume of compressed gas available for a firing operation is reduced, thereby requiring an increased operating pressure to achieve the same paintball velocity. The increased chamber pressure can result in a shorter recharge time and less velocity drop off in successive shots.

  • Publication number: 20070068526
    Abstract: The invention relates to a device for supplying a respiratory gas, in particular a CPAP device and also to an air-conduction structure that is provided in said device. The aim of the invention is to provide a device of this type for supplying a respiratory gas, which is characterised by a silent operation and which has advantages in terms of the assembly method and of hygiene over conventional devices of this type. This is achieved by a device for supplying a respiratory gas, comprising a transport unit for transporting said gas at a pressure level that exceeds the ambient pressure, a housing for receiving the transport device and an air-conduction structure for guiding the respiratory gas from the transport device to an outlet region, said air-conduction device being configured by a moulded foam part comprising respiratory-gas channels.

    Abstract: A sensor may be placed on a patient to obtain physiological measurements. The application of the sensor on the patient may start a timer set to run for a given time interval. If the sensor is repositioned before the interval is expired, the timer is reset. If the time expires without the sensor being repositioned, a caregiver is prompted to reposition the sensor.

  • Publication number: 20070068528
    Abstract: The invention concerns a method and apparatus for determining the status of a ventilated lung. For determining the status of a lung ventilated, which enables in real time optimal ventilatory settings for a recruitment maneuver of an ailing lung, the invention comprises a sensor for measuring a gas concentration in the expired gas during a single breath, an analog to digital converter for obtaining data samples of said gas concentration in the time domain, means for selecting a plurality of data samples, means for calculating a mean tracing value being sensitive to changes of alveolar dead space based on said samples, and a data processor which detects during a change of the airway of the ventilator from the resulting course of calculated mean tracing values the peak inspiratory pressure at which alveolar opening or lung overdistension occurs and/or the PEEP at which lung open condition or alveolar closing occurs.

  • Publication number: 20070068529
    Abstract: A respirator 10 that has a mask body 14 and a malleable nose clip 12. The mask body 14 is adapted to fit at least over the nose and mouth of a person to define an interior gas space that is separate from the exterior gas space. The mask body 14 has the nose clip 12 secured to it and can include at least one layer of filter media 20. The malleable nose clip 12 comprises a semi-crystalline polymeric material that has an integrated diffraction intensity ratio of at least about 2.0. The nose clip 12 can be deformed into a desired configuration that enables the mask body 14 to maintain a snug fit over a person's nose when the respirator is worn for extended time periods. Because the nose clip 12 does not need to contain metal, the whole respirator 10 can be easily processed as waste in an incinerator when its service has ended.

  • Publication number: 20070068530
    Abstract: A pulmonary secretion clearing ventilation catheter and related airway management system is disclosed. The ventilation catheter has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patent through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. An improved inflatable cuff is also disclosed that permits a slight air leakage in the pneumatic seal between the patient's lungs and the environment, thereby facilitating removal of pulmonary secretions from the patient's lungs.
