Claim 1

Independent Claim 198 words

In a resuscitator which facilitates the manual placement and subsequent ventilation of a patient''s lungs, a face mask having an attenuated periphery adapted to engage a patient''s face around the nose and mouth, an opening formed substantially through the center of said face mask, a tubular air-way member removably mounted in said opening, said tubular air-way member having a straight portion extending axially through said opening and projecting beyond the inner and outer sides of said face mask, a detachable joint securing said straight portion to said face mask, said straight portion having a series of longitudinally spaced exterior ribs having crests thereon formed on a large diameter than the interior diameter of said opening and a longitudinal key projecting from said straight portion radially outwardly from said ribs, a key receiving, blind end slat formed in the body of said face mask and in open communication with said opening, a curved end portion on the inner side of said air-way adapted for insertion into a patient''s mouth, and a fitting on the outer end of said air-way to serve as a connection to a resperator bag and as a mouth piece for use in mouth-to-mouth resuscitation procedures.

Claim 2

Dependent Claim 198 words

In a resuscitator which facilitates the manual placement and subsequent ventilation of a patient''s lungs, a face mask having an attenuated periphery adapted to engage a patient''s face around the nose and mouth, an opening formed substantially through the center of said face mask, a tubular air-way member removably mounted in said opening, said tubular air-way member having a straight portion extending axially through said opening and projecting beyond the inner and outer sides of said face mask, a detachable joint securing said straight portion to said face mask, said straight portion having a series of longitudinally spaced exterior ribs having crests thereon formed on a large diameter than the interior diameter of said opening and a longitudinal key projecting from said straight portion radially outwardly from said ribs, a key receiving, blind end slat formed in the body of said face mask and in open communication with said opening, a curved end portion on the inner side of said air-way adapted for insertion into a patient''s mouth, and a fitting on the outer end of said air-way to serve as a connection to a resperator bag and as a mouth piece for use in mouth-to-mouth resuscitation procedures.

Claim 3

Dependent Claim 154 words

In a resuscitator which facilitates the manual placement and subsequent ventilation of a patient''s lungs, a dome-shaped face mask having a relatively thick central body portion and an attenuated, flexible periphery curved inwardly to terminate in a thin, marginal edge adapted to engage a patient''s face around the nose and mouth and to provide an air-tight seal therebetween, detachable couplding means comprising an opening formed substantially through the center of said face mask, a tubular air-way removably mounted in said coupling means, said tubular air-way member having a straight portion extending axially through said coupling means and projecting beyond the inner and outer sides of said face mask, a curved end portion on the inner side of said air-way adapted for insertion into a patient''s mouth, and a fitting on the outer end of said air-way to serve as a connection to a respirator bag and a mouth-piece for use in mouth-to-mouth resuscitation procedures.

The resuscitator set forth in claim 1 wherein a mouth engaging shield projects from the air-way member intermediate it''s straight portion and it''s curved portion.

Claim 6

Dependent Claim 41 words

The resuscitator set forth in claim 3 wherein said striaght portion is provided with a series of longitudinally spaced exterior ribs having crests thereon formed on a large diameter than the interior diameter of said coupling means in said face mask.

Claim 7

Dependent Claim 48 words

The resuscitator set forth in claim 4 wherein said coupling means further comprises a longitudinal key projecting from said striaght portion radially outwardly from said ribs, and a key receiving, blind end slot in the body of said face mask and in open communication with said coupling means.
