    摘要: The apparatus provides for the determination of the instantaneous phase in the respiratory cycle, subject's average respiration rate and the provision of ventilatory assistance. A microprocessor (16) receives an airflow signal from a pressure transducer (18) coupled to a port (17) at a mask (11). The microprocessor (16) controls a servo (19), that in turn controls the fan motor (20) and thus the pressure of air delivered by the blower (10). The blower (10) is coupled to a subject's mask (ii) by a conduit (12). The invention seeks to address the following goals: while the subject is awake and making substantial efforts the delivered assistance should be closely matched in phase with the subject's efforts; the machine should automatically adjust the degree of assistance to maintain at least a specified minimum ventilation without relying on the integrity of the subject's chemoreflexes; and it should continue to work correctly in the presence of large leaks.

    摘要: CPAP treatment apparatus is disclosed having a controllable flow generator (34, 38, 40) operable to produce breathable gas at a treatment pressure elevated above atmosphere to a patient by a delivery tube (32) coupled to a mask (30) having connection with a patient's airway. A sensor (44, 50, 56, 58) generates a signal representative of patient respiratory flow, that is provided to a controller (54, 62, 64). The controller (54, 62, 64) is operable to determine the occurrence of an apnea from a reduction in respiratory airflow below a threshold, and if an apnea has occurred, to determine the duration of the apnea and to cause the flow generator (34, 38) to increase the treatment pressure. In one preferred form the increase in pressure is zero if the treatment pressure before the apnea exceeds a pressure threshold. Below the pressure threshold the increase in pressure is an increasing function of the duration of the apnea multiplied by the difference between the pressure threshold and the current treatment pressure.

    摘要: A tool for laying sequential courses of tiles on an inclined roof, or sidewall the tool including a rail and several arms sized to extend over a previous course of tiles and to position the rail to define a straight edge for the current or new tile course. The arms extend over the current course and their ends are nailed or otherwise secured to the roof or sidewall. After the course is laid, the rail is moved up for the next course. A kit is formed of one or more rails, sets of arms, each set being sized and/or hinged for a corresponding type of tile, and means of interconnecting and aligning the rails. Two rails may also be used to provide roofing on a roof having two sections joined by a valley. For this configuration, a curved, flexible connector is used which is formed of a rubber pipe.

    摘要: An improved ventilator which delivers ventilatory support that is synchronized with the phase of the patient's respiratory efforts and guarantees a targeted minimum ventilation. Improved synchronization is achieved through an instantaneous respiratory phase determination process based upon measured respiratory airflow as well as measured respiratory effort using an effort sensor accessory, preferably a suprasternal notch sensor. The ventilator processes a respiratory airflow signal, a respiratory effort signal and their respective rates of change to determine a phase using standard fuzzy logic methods. A calculated pressure amplitude is adjusted based upon the calculated phase and a smooth pressure waveform template to deliver synchronized ventilation.

    摘要: An improved vertical lift door roller assembly has a wheel pivotally mounted to a shaft. The shaft is placed within a spring loaded locking cylinder. The locking cylinder is movable between a first position where it restricts pivoting of the wheel and a second position where the wheel is able to pivot. The door roller assembly is mountable to a support a vertical lift door, such as a bracket or a hinge. The roller wheel can be pivoted to decouple the roller from a vertical lift door wheel track and to reseat the wheel in the track.
