Abstract: The present disclosure relates generally to medical devices and, more particularly, to a gas mixing system for a medical ventilator. A gas mixer is provided to adjust the oxygen concentration of environmental air for a blower-based ventilator, by adjusting the mix of air upstream of the ventilator and providing the mixed air to the ventilator's environmental air inlet.

Abstract: A hydroponic plant growth system including an upwardly extending housing having a cavity therein defining a liquid nutrient flow column and a plurality of growth pod ports each extending from a respective port opening at an outer surface of a front wall of the housing to the cavity. Each growth pod port sized to receive a growth pod. Wherein when a growth pod is mounted in a respective one of the growth pod ports, a mounting flange of the growth pod abuts the outer surface the front wall and a growth pod axis of the growth pod extends downwardly from a respective growth pod proximal end through the growth pod port at an angle of between 30 degrees and 60 degrees to the growth pod port axis.

Abstract: A cannula for connecting a medical device to a biological system is taught. The cannula includes a tissue engagement portion, preferably in the form of an annulus, to which a vacuum is applied through the cannula to attract and hold tissue of the biological system in an initial connection while an affixment device is applied to complete the connection. In addition to a working fluid conduit, comprising a main port, a working fluid passage and a working fluid port, and a port to apply the vacuum, the cannula can include a sensor port to allow sensing pressure or other characteristics of the working fluid at a point closely adjacent to the connection between the cannula and the biological system.

Abstract: A portable device including a housing comprising a first opening and a second opening and a resuscitator bag. The resuscitator bag is disposed at least partially within the housing and includes an air inlet supported at the first opening of the housing, an air outlet supported at the second opening of the housing, and a self-inflating bag. The portable device also includes a double-sided compression mechanism disposed within the housing. The double sided-compression mechanism includes a pair of arms at least partially surrounding the self-inflating bag. The pair or arms are configured to move towards each other to compress the self-inflating bag to provide positive pressure ventilation via the air outlet and to move away from each other to enable re-inflation of the self-inflating bag via the air inlet; and, a motor coupled to the pair of arms for moving the pair of arms towards and away from each other.
