Apparatus for measuring the parameters of respiratory gases
First Claim
1. An apparatus for simultaneously measuring respiratory gas parameters comprising a respiratory tube and ultrasonic sensors and preamplifier electronic circuitry which is arranged in a housing separate from the respiratory tube, said ultrasonic sensors are embedded within tubular heads formed on the respiratory tube so that they constitute a single part therewith and wherein at least the respiratory tube with the embedded ultrasonic sensors is designed to form a disposable part for use only once;
- said apparatus further comprising a pressure sensor integrated in the respiratory tube, wherein the pressure sensor is cast in the respiratory tube.

Abstract
The invention relates to an apparatus for measuring the parameters of respiratory gases comprising a respiratory tube, ultrasonic sensors and pre-amplifier electronic circuitry arranged in a separate housing. In order to prevent dangerous cross infections between patients following repeated utilization of the such measuring apparatus the ultrasonic sensors are permanently integrated in the respiratory tube so that they constitute a single part therewith and in that at least the respiratory tube together with the integrated ultrasonic sensors is designed in the form of an interchangeable part for use once only.
