Positive Pressure Ventilator · 模型 186706
Our design consists of already manufactured parts. This design is made up of easy-to-obtain parts that can be assembled into working ventilators. The focus of this design was to not add any additional manufacturing steps or delays, by making the ventilator from already from existing parts, it will be easier to mass produce them anywhere in the world. The design is an assembly of an Ambu-Bag, a timer and switch valve, and a gas monitor. The air line connects directly to the hospital supply while the switch and timer controls the beats per minute, and the gas monitor controls the oxygen percentage allowed for the patient. The Ambu-bag includes many vital parts such as an exact controlled 400cc of air, a peep valve, and filters to protect others after exhalation. This system works off the positive pressure inside the lungs of the patient to empty the Ambu-bag and naturally exhale. The switch valve will then open back up allowing the next breath to occur. Material Selection The materials chosen for our design were picked for very specific reasons whether it be for convenience and abundance or for desired features. The Child Ambu Spur II Ambu-bag was selected because it had the desired tidal volume of 400cc. This bag also includes a peep valve adjustable in increments of 5 cmH20, an exhalation valve, and the necessary filters to protect others. The inlet gas monitor will control the volume, pressure, and percentage of oxygen flowing through the system from the hospital infrastructure. Finally, the timer and switch value can be set to control both the breathes per minute and the I:E ratio.
