| 发明名称 | Multifunctional control valve for gas measurement instruments | ||
| 摘要 | A multifunctional control valve for gas measurement instruments, e.g., for respiratory gas analysis, is disclosed. In at least one embodiment, the multifunctional control valve includes a first inlet opening, an outlet opening, a main line, and a bypass line, wherein a measurement chamber is in the main line, wherein the measurement chamber is arranged downstream of a first multiway valve which can selectively connect the main line or the bypass line with the inlet opening, and wherein the measurement chamber is arranged upstream of a second multiway valve which can selectively connect the main line or the bypass line with the outlet opening. | ||

| 主权项 | 1. A respiratory gas analyzer, comprising: a first inlet opening, the first inlet opening being a mouthpiece of the respiratory gas analyzer; an outlet opening; a first flow path, the first flow path being a mainline; a second flow path, the second flow path being a bypass line that bypasses the first flow path; a measurement chamber in the main line; a first multiway valve switchable between at least three functional positions to selectively connect the first flow path or the bypass line with the inlet opening; and a second multiway valve switchable between at least three functional positions to selectively connect the first flow path or the bypass line with the outlet opening, wherein the measurement chamber is arranged downstream of the first multiway valve and upstream of the second multiway valve. | ||
