Abstract: A breathing apparatus with improved ergonomic aspects to more comfortably accommodate patients breathe while preventing their lungs from collapsing. The present breathing apparatus comprises an apparatus body having proximal and distal ends with at least one hollow passageway extending therebetween. A pair of nostril-engaging stems with generally D-shaped base configurations conform to the anatomy of patient's nostrils and a connector assembly having a rotatable mid portion is used at the apparatus body's distal end to allow moderate movement and thereby reduce torque applied to a patient's face.

Abstract: A latch assembly for a lock adaptable for use with inswinging, outswinging, right hand and left hand mounted doors includes a latchcase assembly having a vertically extending slot. A bolt is mounted for sliding movement within the latchcase. A first rotatable cam having a hub is mounted within the vertical slot of said latchcase assembly for sliding the bolt between bolt engaged and disengaged positions. The height of the latchcase slot is larger then the diameter of the hub portion of the cam to accommodate limited vertical movement of the cam within the slot. The vertical position of the cam is shifted within the vertical slot to maintain the horizontal center line of the cam in a predetermined spaced vertical position relative to the horizontal center line of the bolt.
