| 发明名称 | Ventilator apparatus | ||
| 摘要 | Ventilator apparatus provides a breathing circuit for supplying breathing gas to a patient. The breathing circuit includes a variable volume enclosure (3) provided within an enclosure chamber (2) and a gas supply path (21) into the enclosure chamber enabling the enclosure chamber to be pressurized by the supplied gas in order to vary the volume of the enclosure. An alternative path (9) for the gas supply is provided enabling the gas supplied, in predetermined circumstances, to enter directly into the breathing circuit via a valve (4). The gas supply path into the chamber is directed such that as a result of gas passing into the enclosure chamber the valve is biased more firmly to a closed condition. | ||

| 主权项 | 1. Ventilator apparatus comprising: a breathing circuit for supplying breathing gas to a patient, the breathing circuit including: a variable volume enclosure provided within an enclosure chamber;a gas supply path into the enclosure chamber being provided, permitting the enclosure chamber to be pressurized by the supplied gas in order to vary the volume of the variable volume enclosure; andan alternative path for the gas supply being provided enabling the gas supplied, in predetermined circumstances, to enter directly into the breathing circuit via valve means; wherein the gas supply path into the enclosure chamber is directed away from the valve means thereby reducing the enclosure chamber-side pressure at the valve means such that as a result of gas passing into the enclosure chamber the valve means is biased more firmly to a closed condition. | ||
