Breathing gas delivery system and holding clip member therefor

Breathing gas delivery device for gas and air to be breathed by the wearer and for attachment to the nose septum of the wearer, comprising:

• a) a frame means including a generally U-shaped clip portion which includes a base and a pair of legs having outer ends and inside surfaces which legs are spring biased toward each other and at said outer end of which legs on said inside surfaces thereof are projection means for engaging the calumella of the wearer's nose septum, said frame means also having a pair of side frame pieces each of which is spaced outwardly of said clip and which are generally parallel to each other and to said pair of legs, said side frame pieces and said legs being interconnected at least in part by cross support frame pieces, said side frame pieces extending away from the wearer's nose so that finger pressure applied on said side frame pieces squeezes said side frame pieces towards each other which thereby separates said legs and said projection means for attachment and removal of the device from the calumella,
• b) a pair of spaced apart air intake tubes supported in said frame with one each of said air intake tubes leading to a nasal opening,
• b) sealant pad means for each nostril opening attached to said frame means such that an air intake tube for each nostril extends through said sealant pad means whereby said sealant pad means closes the nasal passage opening and permits inhaled air to pass into said air intake tubes and thence into the wearer's nose, and
• d) filter holder means connected to said frame means and to said air intake tubes and having air filter material or inhalent cartridge means therein for filtering air breathed in and passing in therethrough into said air intake tubes.
