    Abstract: 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.

    Abstract: PLURAL DOSAGE AUTOMATIC INJECTOR WITH IMPROVED SAFETY A plural dosage automatic injector (10) comprising an elongated tubular housing assembly (12) having side by side first and second medicament injecting assemblies (14 and 18) each including a container (48 and 116), a hypodermic needle (56 and 130), a liquid medicament (54 and 128) and a plunger (50 and 126) within the forward end portion thereof and, first and second stressed spring assemblies (16 and 20) in the rearward end portion thereof disposed in operative relation with said first and second medicament injecting assemblies for operating the latter. A manually operable safety device (22) is provided which includes a first safety pin (24) operable (1) when in a safety position with respect to the first spring stressed assembly to prevent actuation and release thereof and (2) when removed from its safety position to permit the actuation and release of the second stressed spring assembly. A mechanical motion transmitting mechanism (28) is provided which is operable to transmit a movement occurring as a result of the actuation and release of the first stressed spring assembly into a secondary actuating movement operable to (1) effect a relative movement between the automatic safety pin and the second stressed spring assembly sufficient to remove the automatic safety pin from its safety position and (2) thereafter actuate and release second stressed spring assembly to operate the second medicament injecting assembly.

    Abstract: AUTOMATIC MEDICAMENT INGREDIENT MIXING AND INJECTING APPARATUS An automatic injector apparatus comprising an outer housing assembly, a hypodermic needle, first and second containers, a first liquid medicament ingredient in the first container and a second medicament ingredient in the second container, first and second pistons in the first and second containers respectively, a releasable stressed spring arrangement capable of being released twice, once for movement through a first piston moving stroke and second through a second piston moving stroke, a first releasing device operable in response to a first predetermined actuating procedure for accomplishing a first release of the spring arrangement so as to effect movement of the first piston through a liquid medicament ingredient moving stroke causing the liquid medicament ingredient to mix with the medicament ingredient in the second container to form liquid medicament and a second releasing device operable in response to a second actuating procedure for accomplishing a second release of the spring arrangement so as to effect movement of the second piston through an operative stroke causing the hypodermic needle to be moved into the muscle tissue of the patient and the liquid medicament to be moved through the needle into the muscle tissue of the patient.
