Metering system for stimulating bronchial spasm |
摘要 |
A system for administering a metered dose of nebulized antigen tests a patient's pulmonary response. The system includes a thermistor detector for sensing initiation of patient inhalation. A variable electronic timer meters the amount of nebulized antigen introduced to the patient. Safety switching means is provided for insuring against erroneous administration of more than a single dose at a time. Separate measuring equipment is used to measure pulmonary airflow resistance which will increase in response to bronchial spasm.
