  • Patent number: 6360745
    Abstract: The invention is directed to a ventilation control system and method of powering up a patient ventilator for detecting if a patient is connected to the ventilator when the ventilator is initially powered up prior to input of ventilator settings. The ventilation control system utilizes a user-friendly user interface for the display of patient data and ventilator status, as well as for entering values for ventilation settings to be used to control the ventilator. Values for ventilation settings entered during set up of the ventilator result in the display of only those further ventilation settings that are appropriate in accordance with the earlier entered settings.

  • Patent number: 6345620
    Abstract: The present invention provides a flexible respirator filter having substantially coextensive front and back portions of filter material which are sealed to each other along their periphery, forming a sealed edge. A flexible plastic frame is contained within the front and back portions to form a plenum between the front and back portions of filter material. The frame has a peripheral edge which remains adjacent to the sealed edge of the filter material along substantially the entire length of the sealed edge to provide sufficient rigidity to prevent crushing while at the same time providing sufficient flexibility to fit under other personal protective equipment. A connector for attaching the filter to the respirator mask is formed integrally with the frame such that it protrudes through the back portion of the filter material. A plurality of recesses are also formed integrally with the frame to facilitate grasping the filter without crushing or damaging it.
