  • Publication number: 20160346500
    Abstract: An application for a disposable support/resuscitation system includes a pressurized gas inlet connected to a pressure relief device. The pressure relief device has a first pressure relief valve that opens at a setable gas pressure and, optionally, has a second pressure relief valve that opens at a pre-determined maximum gas pressure. Changing the first pressure release valve from a low pressure range to a high pressure range requires activation of a pressure range actuation button. A manometer is connected to the pressure relief valve. A manually operated valve is connected to the manometer, and a patient interface port is connected with the manually operated valve. The manually operated valve selectively controls administration of the pressurized gas to the patient. The manometer, pressure relief device, and manually operated valve are made from non-ferromagnetic materials for proper operation in the vicinity of a Magnetic Resonance Imaging System.

  • Patent number: 8534283
    Abstract: 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.
