  • Patent number: 8584674
    Abstract: The invention discloses a safety mechanical system by which emergency oxygen is delivered to motor vehicle occupants during an accidental water submersion of the vehicle. The system utilizes an oxygen filled tank located in the trunk, or another concealed area. The tank is connected to a manifold system with an automatic valve. The valve is activated and opened when a series of sensors detects that the vehicle is partially or fully submerged. Upon such detection, the valve is opened and oxygen is delivered through the manifold, then to a series of flexible tubes to a set of drop down masks that automatically deploy from an overhead console in the vehicle's headliner. The drop down assembly is of an adequate length of coiled hose similar to that found on a commercial airliner for oxygen use during sudden decompression. With such an installed system, vehicle occupants are provided with a mask and oxygen until they can be rescued or escape on their own.

  • Patent number: 8522780
    Abstract: A portable ventilator uses a ROOTS-type blower as a compressor to reduce both the size and power consumption of the ventilator. Various functional aspects of the ventilator are delegated to multiple subassemblies having dedicated controllers and software that interact with a ventilator processor to provide user interface functions, exhalation control and flow control servos, and monitoring of patient status. The ventilator overcomes noise problems through the use of noise reducing pressure compensating orifices on the ROOTS-type blower housing and multiple baffling chambers. The ventilator is configured with a highly portable form factor, and may be used as a stand-alone device or as a docked device having a docking cradle with enhanced interface and monitoring capabilities.

  • Publication number: 20130220319
    Abstract: An apparatus for producing gas for use in medical applications. The apparatus includes a compressed gas unit having at least one container of compressed gas and a solenoid valve. An adjustable pressure regulator communicably connected to the gas container, separate and distinct from the solenoid valve, is adjusted to control the pressure of the gas provided from the container to the solenoid valve. An electrical power source is connected to the solenoid valve. A pressure activated electronic switch connected to the power source is responsive to a selected amount of voluntary fingertip, pressure for opening the solenoid valve to transmit the gas therethrough to a conduit, which further transmits the gas to a destination for use or storage.

  • Patent number: 8517014
    Abstract: A method for relating to each other cardiovascular and sleep disordered breathing conditions of a patient. The patient's heart rate and/or detailed echocardiogram data is monitored and recorded continuously or periodically together with sleep disordered breathing information on similar time scales. Changes in the patient's heart rate associated with changes in sleep disordered breathing can then be observed. More specifically, positive airway pressure at therapeutic levels for treatment of sleep disordered breathing is applied while events associated with the treatment of the patient's sleep disordered breathing are detected and recorded. At the same time, information concerning the cardiovascular condition of the patient is stored and the stored information concerning the cardiovascular condition of the patient and the recorded events associated with the treatment of the patient's sleep disordered breathing are related to each other.

  • Patent number: 8517015
    Abstract: Methods and systems for delivering a pharmaceutical gas to a patient. The methods and systems provide a known desired quantity of the pharmaceutical gas to the patient independent of the respiratory pattern of the patient over a plurality of breaths every nth breath, where n is greater than or equal to 1. The pharmaceutical gases include CO and NO, both of which are provided as a concentration in a carrier gas. The gas control system determines the delivery of the pharmaceutical gas to the patient to result in the known desired quantity (e.g. in molecules, milligrams or other quantified units) of the pharmaceutical gas being delivered. Upon completion of that known desired quantity of pharmaceutical gas over a plurality of breaths, the system can either terminate, continue, activate and alarm, etc.

  • Patent number: 8517012
    Abstract: A multiple stage variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the multiple stage blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.

  • Patent number: 8511307
    Abstract: 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.
