摘要:
The present invention relates to oxygen sensors for medical ventilators. A medical ventilator includes a patient circuit delivering inspiratory airflow to a patient and returning expiratory airflow from the patient back to the ventilator. A manifold includes an air flow path into the patient circuit, and a port with an opening for an oxygen sensor. When mated to the port, the oxygen sensor samples the air in the air flow path and detects the amount of oxygen in the air. When the oxygen sensor is inserted into the port, a valve is biased open, to allow airflow through the opening into the oxygen sensor during ventilation. When the oxygen sensor is removed from the port, the valve biases into a closed position covering the opening, to prevent leaks. The ventilator can then continue to operate without the oxygen sensor in place.
