RESPIRATORY MEASUREMENT APPARATUS HAVING INTEGRATED FILTER

摘要

An apparatus comprises a flow sensor configured to sense airflow between a respiration machine and a patient, a first connector configured to communicate air between the flow sensor and the patient, a second connector configured to communicate air between the flow sensor and the respiration machine, multiple pressure sensing ports configured for connection to pressure sensing tubes and configured to communicate gas pressure between the flow sensor and a pressure flowmeter, and a filter integrated with the flow sensor between the first connector and the pressure sensing ports and configured to communicate gas pressure therethrough while preventing contaminants from passing from the flow sensor to the pressure sensing tubes.

1. An arrangement for measurement of respiratory flow or respiratory gases in an airway between a patient and a ventilator or respirator, the arrangement comprising:
an adapter comprising a housing having first through fourth openings; a first connector attached to the adapter at the first opening and configured for connection to a first hose leading toward the ventilator or respirator; a second connector attached to the adapter at the second opening and configured for connection to a second hose leading toward the patient; third and fourth connectors attached to the adapter at the third and fourth openings and configured for connection with pressure sensing tubes to be used in conjunction with a differential pressure flow sensor located along a path between the first and second connectors; and a filter integrated with the housing of the adapter and configured to prevent patient originated infective agents from contaminating the pressure sensing tubes.
