摘要:
Apparatus for resuscitating a plurality of patients comprising four face mask assemblies each of which is operable to be operatively connected with a patient so as to permit fresh air to be supplied to the lungs of such patient and four bellows assemblies actuated by a cam track rotated either by a suitable clutched electric motor or by hand crank for delivering successive volumes of fresh air under pressure to each face mask assembly at a desired cyclical frequency wherein each cycle includes said fresh air delivery as a minor part thereof. Each face mask assembly has operatively associated therewith (1) a stale air exhaust valve assembly for permitting air expelled from the lungs of each patient during the remaining major part of each cycle associated therewith to be exhausted to atmosphere, (2) a medicament injector for selectively supplying a respiratory medicament dosage into the fresh air delivered to each face mask assembly, and (3) a pressure gauge for indicating the operative pressure adjacent the face mask assembly so as to enable the operator to readily determine a bronchoconstrictive condition of a patient operatively connected with the associated face mask assembly so that the associated selective medicament injector is selected to deliver medicament only during the minor cycle part when the fresh air is delivered.
摘要:
An assembly for enabling a respiratory medicament to be administered to a gas mask wearer without breaking the seal between the face blank of the gas mask and the wearer's face. The assembly comprises a container, a respiratory medicament dosage releasably disposed within the container, and a shroud covering the container for (1) interiorly communicating with the exterior of a normally closed passage extending through the face blank of the gas mask to the sealed interior thereof, (2) exteriorly isolating the container and (3) enabling the respiratory medicament dosage to be released from the container while the interior communicating and exterior isolating relationships are maintained.
