APPARATUS FOR CONTROLLED AND AUTOMATIC MEDICAL GAS DISPENSING

摘要

Apparatus for supplying in a controlled and automatic way boli of nitric oxide (NO) to patients ' (50) ' affected by respiratory diseases. The appara tus comprises a reservoir (20) connected an electro-valve (21) for adjusting the flow. The electro-valve (21) is switched on/off by a microprocessor (40 ) in order to supply the medical gas contained in the reservoir, (20) in syn chronism with the respiratory rhythm of the patient (50). This rhythm can be outlined on the basis of the temperature values of the respiration flow by measuring, means (80) comprising a first thermistor (81) and a second thermi stor (82) electrically connected to each other. The temperature values are t hen computed by the micropocessor (40). The flow controlled is sent to the r espiratory airways of the patient (50) through a thin nasal tube (2).
