    Abstract: Oxygen to be administered to a patient is humidified by passing the oxygen through a standard water-containing solution bottle. A coupling assembly having an inlet tube and an outlet tube is inserted into the two openings defined by the stopper of the intravenous solution bottle, and is coupled to an oxygen supply. The connector assembly is capable of supporting the bottle, and carries a humidified oxygen outlet to which an oxygen administration device is coupled.

    Abstract: A power line fault indicating system adapted to be connected in parallel with an electrical appliance for detecting the most common power line faults. The system employs a neon lamp connected in an R-C oscillator circuit which is controlled by circuitry responding to power line conditions to provide any one of three states of the lamp, namely, steady energization of the lamp, blinking of the lamp, or steady deenergization of the lamp, depending on different conditions. The circuitry includes a power supply stage, a logic stage, an averaging and delay stage, and a driver stage connected to a resistor forming part of the oscillator discharge circuit branch and arranged so as to shortcircuit this resistor under normal power line circuit conditions and thereby allow the neon lamp to be steadily energized, and to remove the short circuit under certain abnormal power line conditions and thereby cause the oscillator to operate and provide blinking action of the lamp. Other abnormal power line conditions will prevent energization of the lamp.

    Abstract: An improved meat tenderizing system is provided in which hoses are individually, manually controlled to feed selected, metered amounts of an enzyme injection solution to injection needles. The injection solution is distributed to a number of hoses through a manifold and a manually operable flow meter is coupled to each hose upstream of the injection needles and downstream of the manifold.

    Abstract: A signal processing circuit for use in a digital memory-type EKG display system wherein analog EKG signals are periodically sampled and converted to a digital signal for processing and display comprises an amplitude hold circuit which maintains the instantaneous amplitude of pacemaker pulses contained in the analog EKG signal constant for a sufficient period of time to insure recognition of the pulses in the next sampling. Because no access is required to the sampling or conversion circuits of the system, the processing circuit can be readily added to an existing system.

    Abstract: A reservoir for the collection, purification, and storage of blood during surgical procedures which comprises a hollow blood storage casing having a hollow, perforated member within said casing extending from end-to-end thereof. Blood defoaming means and a filter are carried by the hollow member, so that the blood defoamer and filter are noncollapsible, and extend the entire length of the chamber within the casing, with one of the ports communicating with the interior of the hollow member, so that blood passes through the perforations of the hollow member and defoamer-filter means.

    Abstract: An emergency alertable gravity feed cardiopulmonary bypass system is disclosed in which a blood volume responsive transducer is utilized in returning oxygenated blood to a human circulatory system at a pumping rate corresponding to venous drainage or selected norms. The transducer is coupled to a standpipe and is responsive to a confined gas volume therein related to the blood volume in a first air evacuable, gravity fed, collapsible bag and is coupled to a rate setting control. Blood flow from the first bag is directed by a control responsive oxygenation pump through a membrane oxygenator and heat exchanger and air evacuable collapsible bag and a main pump before return to the patient. The oxygenation pump rate slaved to the main pump is greater than the gravity feed rate, and a pressure relieving conduit recirculates excess blood flow from the second bag to the first bag. Supervisory control of the flow rate of the main pump may be exercised by manual adjustment of the flow rate.
