  • Patent number: 4241732
    Abstract: An arrangement is provided in a respirator for measuring the amount of gas passed to a patient through a supply line. The arrangement includes a self-oscillating fluidistor for dividing the gas flow into part volumes of a given magnitude and for generating an electrical pulse for each part volume passing therethrough. The fluidistor includes two outputs and a control channel having a temperature-dependent resistor located therein and an amplifier and pulse-forming circuit connected to the resistor so as to generate electrical pulses whose number is related to the number of part volumes flowing through the control channel of the fluidistor. A binary counter is connected to the amplifier and pulse-forming circuit for counting the number of pulses over a predetermined time interval while a digital-to-analog (D/A) converter, having first and second inputs, generates an analog signal corresponding to the number of pulses produced per time interval.

  • Patent number: 4241738
    Abstract: A housing contains a light source, a monochromator, a photosensitive unit and an oscilloscope-type display. A flexible bundle of fiber-optic elements extends from within the housing out, and is provided at its outer end with a spacing ring. The spacing ring is placed against a skin surface, holding the ends of the fiber-optical bundle properly spaced and oriented relative to the skin surface. At the other end of the bundle, the bundle is subdivided into one branch which receives light from the source, and another branch which emits light refleced from the skin surface into the monochromator. The monochromator projects the spectrum of the skin-reflected light onto the photosensitive unit. The output signal of the photosensitive unit, in a sequential and periodic manner, contains information concerning successive spectral components of the skin-reflected light. The sweep of the display is synchronized with this periodic sequence, so as to display a spectral analysis of the skin-reflected light.

  • Patent number: 4241729
    Abstract: The present invention discloses herewith an endoscope by which pressurized air is led into an inner portion of the endoscope. A plug of a light-transmitting optic bundle tube which communicates with the inner portion is covered, partially or totally, by a gas-tight cap which has a pressure inlet. The pressurized air is led from the pressure inlet into the inner portion of the endoscope through a terminal part or a gap of the plug.By these provisions, an internal pressure of the endoscope is raised to an extent not smaller than the external pressure of a cleanser in order to prevent the cleanser from flowing into the inner portion of the endoscope when washing and/or sterilizing a non-waterproof endoscope. In addition, a pinhole on a flexible sheath can easily be detected by testing a leakage of the pressurized air as for a waterproof endoscope.

  • Patent number: 4240440
    Abstract: A system and method for obtaining a nuclear kymogram of regional wall motion of an organ under study such as a human heart includes injecting a radioisotope into the blood stream which accumulates in the cardiac blood pool or myocardium. A scintillation camera having a reduced generally elongated area of data recordation is positioned overlying a selected portion of the heart and positional "events" occurring along the major axis of the area of recordation are swept across a CRT in synchronism with the ECG signal. Successive real-time displays each in synchronism with the ECG signal are accumulated to provide a nuclear kymogram.

  • Patent number: 4235248
    Abstract: A distributor wherein a belt conveyor transfers batches of tobacco particles from a main magazine into a wide upright duct. The level of different portions of the upper surface of the supply of tobacco in the duct is monitored by several photosensitive detectors which transmit signals for adjustment of a paddle wheel which removes surplus tobacco from the transfer conveyor by brushing off more or less tobacco from different portions of the conveyor, as considered transversely of the direction of movement of the conveyor, in order to maintain the entire upper surface of the tobacco supply in or close to a horizontal plane.

  • Patent number: 4232687
    Abstract: The disclosure is directed to a method and apparatus for determining a newborn infant's capability to orally accept nourishment. In accordance with the method of the invention, a test nipple is inserted in the mouth of an infant. Further method steps comprise measuring the suction which the infant applies to the test nipple, and measuring the expression force which the infant applies to the test nipple. The infant's capability of orally accepting nourishment is then determined as a function of the measured suction and expression. In accordance with the apparatus of the invention, there is provided a test nipple, and first and second transducers adapted for coupling to the test nipple. The first transducer is operative to generate a suction-indicative electrical signal, and the second transducer is operative to generate an expression-indicative electrical signal. A timing circuit is provided for defining successive time intervals.

  • Patent number: 4232685
    Abstract: A larynx stroboscope device capable of photography following the anode or cathode terminal of a flash discharge tube is connected to a photographing charge-discharge capacitor by the release operation of a camera. A trigger pulse is applied to the trigger terminal of the flash discharge tube in synchronization with a vocal cord vibration signal so that the flash discharge tube emits light while the shutter of said camera is open. Upon completion of a photographing operation, all the functions are automatically restored to the states obtained before the release operation. Alternatively, a charge-discharge system may be used. By the release operation of a camera supply of charging current to said capacitor is suspended. Thereafter a trigger pulse is applied to the trigger terminal of said flash discharge tube in synchronization with a vocal cord vibration frequency so that said flash discharge tube emits light while the shutter of said camera is open.
