초록 ▼

A respirator used to replace or assist the respiratory function and automatically regulate the respiration gas flow and pressure during the inspiration phase and expiration phase comprising means for measuring the flow and pressure of respiration gas and providing electrical output signals, valve means including an adjustable valve for controlling the flow and pressure of respiration gas past the measuring means, and electronic regulating means connected with the measuring means and valve means for comparing the electrical signals with predetermined values including standard values and for generating a regulating signal for adjusting the valve means.

대표청구항 ▼

A respirator for automatic regulation of flow and pressure of respiration gas during an inspiration and expiration phase by way of a single conduction path between a source of respiration gas and a patient, comprising: a. a single conduction path having a first end adapted to be connected to a source of respiration gas and a second end adapted to be connected to a patient and, in serial arrangement, measuring means forming part of said conduction path for determining the flow and pressure of respiration gas at a single measuring location proximate the said second end and converting the same into electrical signals; single first valve means forming part of said conduction path and coupled to the source of respiration gas and adapted to be adjustable between inspiration and expiration positions and for controllably varying the flow and the pressure of the respiration gas during the inspiration phase and expiration phase; and single second valve means forming part of said conduction path for separating inspiratory and expiratory flow, said single second valve means being coupled between said single first valve means and said measuring means said second valve means including an outlet, and means between said first and second valve means for providing fluidic connection of the first valve means to the patient during the inspiration phase when said first valve means is in said inspiratory position and for fluidic connection from the patient to said outlet during the expiration phase when said first valve means is in said expiratory position; and b. electronic regulating means connected with the measuring means and said first valve means for comparing said electrical signals with selected values including standard values of inspiratory and expiratory flows and pressures and for generating a regulating signal indicative of a difference between said selected valves and said electrical signals and thereby controllably adjusting said first valve means for flows and pressures of respiration gas during the inspiratory and expiratory phases.
