Systems And Method For Delivery Of Therapeutic Gas To Patients In Need Thereof Using Enhanced Breathing Circuit Gas (BCG) Flow Measurement

摘要

The present invention generally relates to systems and method for delivery of therapeutic gas to patients in need thereof using enhanced breathing circuit gas (BCG) flow measurement. At least some of these enhanced BCG flow measurements can be used to address some surprising phenomena that may, at times, occur when wild stream blending therapeutic gas into breathing gas that a patient receives from a breathing circuit affiliated with a ventilator. Utilizing at least some of these enhanced BCG flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives from a ventilator can at least be more accurate and/or over delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.

主权项

1. A nitric oxide delivery system comprising:
an injector module for delivering therapeutic gas into breathing gas in a breathing circuit, the injector module comprising:
an injector body having a first opening and a second opening, the first opening and the second opening being configured to couple the injector module to a patient breathing circuit; anda therapeutic gas inlet configured to receive therapeutic gas and enable injection of the therapeutic gas into breathing circuit gas flowing through the injector module; at least one sensor capable of measuring at least one characteristic of the breathing circuit gas, wherein the at least one characteristic is one or more of: (i) flow of the breathing circuit gas in a forward direction and in a reverse direction, (ii) a humidity of the breathing circuit gas, (iii) a temperature of the breathing circuit gas, and (iv) a type of gas in the breathing circuit gas; and a control module for providing the therapeutic gas to the therapeutic gas inlet, and the control module being in communication with the at least sensor, wherein the control module compensates delivery of therapeutic gas and/or provides an alert based on the measurement from the at least one sensor.
