Claim 5

Gas delivery apparatus according to claim 3, said connecting strap connected at opposite ends to said elbow-shaped fittings in each of said gas supply conduits.

Claim 6

In an analgesia system, gas delivery means for supplying gaseous fluids from a gas supply source to a nasal inhalator adapted to fit over the nose and be confined to a limited area of a patient''s face in closely surrounding relationship with the nose of the patient leaving the patient''s mouth uncovered wherein said inhalator is provided with oppositely directed, open tubular connecting means thereon, said apparatus comprising in combination: first and second gas supply hoses each connected at one end to one of said open tubular connecting means and each adapted to extend laterally away from said inhalator and downwardly for termination at a point along the side of the patient''s head when the patient is in a prone position, first and second extension hoses extending from the terminal ends of said lateral extension hoses for connection to the gas supply source, first and second elbow joints interconnecting the terminal ends of said first and second lateral extension hoses, respectively, with each of said respective first and second extension hoses so that the rearward extension hoses extend in a common direction substantially normal to the lateral extension of said lateral extension hoses, a hose clip adapted to releasably and adjustably hold together the first and second rearward extension hoses at a point over the patient''s head, and a connecting strap connected at opposite ends to said elbow-shaped joints and adapted to pass behind the patient''s neck.

Claim 7

In an analgesia system, gas delivery means for supplying gaseous fluids from a gas supply source to a nasal inhalator adapted to fit over the nose and be confined to a limited area of a patient''s face in closely surrounding relationship with the nose of the patient leaving the patient''s mouth uncovered wherein said inhalator is provided with oppositely directed, open tubular connecting means thereon, said apparatus comprising in combination: first and second gas supply hoses each connected at one end to one of said open tubular connecting means and each adapted to extend laterally away from said inhalator and downwardly for termination at a point along the side of the patient''s head when the patient is in a prone position, first and second extension hoses extending from the terminal ends of said lateral extension hoses for connection to the gas supply source, first and second elbow joints interconnecting the terminal ends of said first and second lateral extension hoses, respectively, with each of said respective first and second extension hoses so that the rearward extension hoses extend in a common direction substantially normal to the lateral extension of said lateral extension hoses, a hose clip adapted to releasably and adjustably hold together the first and second rearward extension hoses at a point over the patient''s head, and a connecting strap connected at opposite ends to said elbow-shaped joints and adapted to pass behind the patient''s neck.

Claim 8

In an analgesia system according to claim 5, said connecting strap having one end looped over and permanently attached to one of said elbow-shaped connections and the opposite end being looped over the other elbow-shaped connection and adjustably attached to regulate the tautness of the strap behind the patient''s neck.

Claim 9

In an analgesia system according to claim 6, said adjustable connecting end including a circular band on said elbow-shaped connection provided with an outer fibrous adhesive surface, and the looped end of said strap at the adjustable connecting end provided with a mating fibrous material for adjustable connection to said circular band.

Claim 10

In an analgesia system according to claim 7, said strap including an elastic portion to permit limited stretching of said strap.

Claim 11

In an analgesia system, gas delivery means for supplying gaseous fluids from a gas supply source to a cupped nasal inhalator adapted to fit over the nose and be confined to a limited area of a patient''s face in closely surrounding relationship with the nose of the patient leaving the patient''s mouth uncovered wherein said inhalator is provided with open tubular connecting means on opposite sides thereof, said apparatus comprising in combination: first and second extension hoses each hermetically connected at a first end to one of said open tubular connecting means and each extension hose providing an extension of said open tubular connecting means away from said inhalator, first and second hollow elbow joints each having first and second open ends directed in substantially normal directions, said first end of each elbow joint being hermetically connected to a second end of an associated extension hose, first and second elongated gas supply hoses having first and second open ends, the first open end of said gas supply hoses being hermetically connected to the second open end of an associated elbow joint so as to extend normally away from the associated extension hose, and the second open end of said gas supply hoses being hermetically connected to said gas supply source, a hose clip movably connected to both gas supply hoses and adapted to adjustably hold together the gas supply hoses at selected locations along their length, and an adjustable connecting strap connected to each of said elbow joints whereby when the inhalator is disposed over a patient''s nose, the elbow joints are adapted to rest on the patient''s cheeks and the adjustable strap is adapted to be passed beneath the patient''s ears and around the patient''s neck to anchor the inhalator on the patient''s face.

Claim 12

In an analgesia system, gas delivery means for supplying gaseous fluids from a gas supply source to a cupped nasal inhalator adapted to fit over the nose and be confined to a limited area of a patient''s face in closely surrounding relationship with the nose of the patient leaving the patient''s mouth uncovered wherein said inhalator is provided with open tubular connecting means on opposite sides thereof, said apparatus comprising in combination: first and second extension hoses each hermetically connected at a first end to one of said open tubular connecting means and each extension hose providing an extension of said open tubular connecting means away from said inhalator, first and second hollow elbow joints each having first and second open ends directed in substantially normal directions, said first end of each elbow joint being hermetically connected to a second end of an associated extension hose, first and second elongated gas supply hoses having first and second open ends, the first open end of said gas supply hoses being hermetically connected to the second open end of an associated elbow joint so as to extend normally away from the associated extension hose, and the second open end of said gas supply hoses being hermetically connected to said gas supply source, a hose clip movably connected to both gas supply hoses and adapted to adjustably hold together the gas supply hoses at selected locations along their length, and an adjustable connecting strap connected to each of said elbow joints whereby when the inhalator is disposed over a patient''s nose, the elbow joints are adapted to rest on the patient''s cheeks and the adjustable strap is adapted to be passed beneath the patient''s ears and around the patient''s neck to anchor the inhalator on the patient''s face.
