Description:FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In a ventilator device, the flow rate of gas needs to be controlled, thus the sensors have been incorporated within the ventilator device to correctly measure the flow rate and pressure to regulate the flow rate of gas. These sensors are prone to the moisture and other contaminants. An example of this is the measurement of flow rates from proximal flow sensors used for neonatal ventilation applications. These flow sensors measure differential pressure close to the patient for improved accuracy and are therefore exposed to the moisture from the patient. This moisture is undesirable to be in contact with the sensor element itself. There is a need to remove condensation formed within the plurality tubes of the ventilator device while simultaneously measuring the characteristics of flow at that location. Existing mechanisms adapt numerors techniques for removing moisture from the pressure sensing tubes, which are expensive, and time consuming. In addition, current technologies used in mechanical ventilation for rinsing tubes add extra rinsing flow in the system to remove condensation from pressure sensing tubes. Thus, resulting in complex design and implementation strategies.
[0004] There is, therefore, a need in the art to develop an apparatus and method for rinsing at least one pressure sensing tube which seamlessly removes the condensed water particles and dust which are formed in the tubes.
