    摘要: A method and apparatus for simulating lung sounds in real time in an integrated patient simulator uses a manikin having an associated simulated lung comprising at least one bellows and at least one sensor for sensing the position of the bellows. Based on a physiological state of the patient simulator, a audible lung sound is directed through a plurality of sound output devices located at different locations on the manikin. The lung sound corresponds to an appropriate physiological sound at that particular location on the manikin and is synchronized with the position of the bellows. Synchronization occurs by continuously determining a volume of the bellows to determine a respiratory phase and a transition in the respiratory phase. The respiratory phase is determined by calculating a first derivative of the bellows volume over time and the transition in the respiratory phase is determined by calculating a second derivative of the bellows volume over time.

    摘要: A diagnostic monitor checks the carbon dioxide (CO.sub.2) content of a gas exiting a patient during endotracheal or esophageal intubation. A plurality of composition portions substantially change color in response to exposure to the carbon dioxide. The composition portions change color in response to different times of exposure to carbon dioxide. A magnifying or condensing lens may be positioned on the monitor to enhance viewing of the color change. The monitor may advantageously be made as part of an intubation system through which the gases from a patient exit the patient. The differences in time of exposure needed to cause the color change may be accomplished by using semipermeable membranes having differing thicknesses, CO.sub.2 permeabilities, and/or surface areas with each membrane corresponding to a particular one of the composition portions.

    摘要: An apparatus and method of simulating breathing sounds in real time involves the use of a manikin having a lung bellows. A sensor associated with the lung bellows is used to continuously determine the volume such that, using standard mathematical procedures based on the time and volume determined, a first derivative of the bellows volume over time can be calculated to determine the phase of the respiratory cycle (e.g. inhalation or exhalation). In addition, by calculating a second derivative of the bellows volume over time, a transition in phase of the respiratory cycle can be determined. Based upon the first and second derivatives of the bellows volume over time, a sound is output through an output device, such as a speaker, located proximate the mouth of the manikin. The outputted sounds are pre-recorded audible sounds of breathing corresponding to appropriate physiological sounds.

    摘要: A self-contained jet pump type breathing apparatus is provided for introducing gases into the lungs of a patient having an inspiratory jet pump for sweeping gases toward the patient, an expiratory jet pump for sweeping exhaled gases away from the patient and an absorber for absorbing carbon dioxide from the exhaled gases which are again supplied to the respiratory jet pump. An anesthetic introduction conduit permits the flow of anesthetic gases into the breathing apparatus. In addition, a jet producer device, is also provided, which obtains fresh compressed gases from the absorber and compressor and supplies pulsating pressurized gases to the respiratory jet pumps.

    摘要: An apparatus and method for synchronizing output devices related to a cardiac rhythm in real time in an integrated patient simulator during simulated medical surgery includes a manikin, at least one output device including devices for simulating a cardiac pulse and a radial pulse, a first computer associated with the patient simulator for generating an electric cardiac rhythm synchronizing pulse, a second computer for receiving the cardiac rhythm synchronizing pulse and generating a simulated response thereto, and a distributed processing network for transmitting the cardiac rhythm synchronizing pulse between the first computer and the second computer and for transmitting the simulated response between the second computer and the output device. In this way, a time offset to allow for simulated travel time or lag of the simulated cardiac pulse through the body can be added by the second computer where appropriate for certain subsystems or monitors associated with the patient simulator.
