초록 ▼

In a respirator having an inspiration gas flow controlled by the expiration gas flow, in order to avoid triggering difficulties, particularly in the neonatal respiration therapy, the respirator is controlled such that a continuous gas flow flows through the inspiration and expiration lines. The gas flow is measured in the inspiration line by a gas flow sensor. The measured signal from the gas flow sensor is used to control a valve in the inspiration line, or a common line connected to the inspiration and expiration lines so that a constant gas flow is maintained in the expiration line.

대표청구항 ▼

A respirator comprising: an inspiration line and an expiration line each connectable to the airways of a patient; a source of respiratory gas; valve means in said inspiration line for setting a flow of respiratory gas from said source to said patient; at least one gas flow sensor disposed for sensing a gas flow in said expiration line; and control means, connected to said valve means and to said gas flow sensor, consisting of means for controlling said valve means dependent on a signal from said gas flow sensor for increasing gas flow through said inspiration line, and means, upon the occurrence of a decrease of gas flow in said expiration line below a selected level as sensed by said gas flow sensor, for bringing the gas flow in said expiration line back to said level.
