Stern Resp BrSt

not sure about the category. iam no engineer, nor medical employee, so this is just my oversimplified (bullshit-)brainstorming. But the problem needs to be solved, maybe my bs/brainstorm results spark some brighter mind. So in this hope here i go....this will update quite frequently final .stl (or other formats) of the models will be uploaded some time later, when the evaluation is more stable. In work, not implemented yet: - connecting rods from 'excentered disc' to control the 'membrane rods' in 'stern-mode' - kinda universal motor shaft adapter (coned?) Two uses, SINGLE DEVICE and multiple SINGLE DEVICES in STERN-MODE. My initial idea was something like a sternengine, an excenter disc, driven by a speedcontrolled motor, would move the rods connected to the membranes (rubber from balls or ballons or something similiar). A one way valve system would secure the flow direction of the moved volume of air. With the movement of the rods, the membran is expanding the volume and pushing the exceed air in the wanted direction. When moving back again, the valve system would let air in from the outer side of the stern. (the valve system is very simple with rubberflaps, but still needs to be integrated in the model) The volume of the membranes would affect the overall amount of moved air with a ratio of 7 to 1. (7 membranes in total) So if one fails and they scaled are large enough to sustain the needed 500ml with a safety factor of 3 (so that 1500ml / breath could be delivered) there is plenty of room. (the system needs to be scaled to deliver 1500ml of air per breath, this is for the cases when something fails or leaks) In this model, there are two different uses. One is a single device, used with an amplifier and a smartphone the other is the devices arranged in a Sternengine-like assembly, driven by a motor. The renderings shows latter. Another try to explain the idea: Think about the monitoring sensors as throttle and brake. Engineer a sound with the correspodending frequency range and use technics like in a simulator (e.g. engine sounds). As the single device use has two elecromagnet mounted, one in 'position 1' and one in 'position 2'. When the same 'ground' is used, the electromagnets in 'position 1' and 'position 2' could be controlled with the stereo signal on either the left or the right channel. (maybe i got a faulty wiring in my head, regarding this partial idea. i have had no time so far to prove this part of the concept.) Use the same mobilephone to interpret the sensors in an app and to influence the base frequency or other modulaties. It would need a mobilephone, an amplifier and a speaker which could be connected to a tube / pipe / pet-bottles, maybe another membran, depending on the speaker. and the relevant sensors that is needed in other ideas too, but is not replaced with the above. the low amplitude of the motion could maybe countered with more surface in the volumetric vessels? On another thought, maybe a lever could be glued to a subwoofer, with a hinge it could move something more appropriate.
