LCV - simple crises emergency ventilator (concept)

thingiverse

This experimental ventilator is a mechanical component of an innovative concept in which a manual resuscitator from emergency medical services is automatically compressed by a mechanism that can be almost entirely produced using laser cutting technology. With this design, it is possible to adjust the air volume and ventilation frequency as needed. A peep pressure can be achieved through a mechanical peep valve, while a redundant electronic function monitoring system with alarm function ensures safe operation of the machine. Some key advantages of this design include: - Can be manufactured using laser cutting techniques for short production times - Large gear ratio of 10:1 enables regular Nema 17 stepper motors to be used effectively - Uniform two-sided compression of the resuscitator eliminates twisting and ensures safety against loss of steps - High compression force provides high safety against loss of steps, making it a reliable option - Easy access to the bag at any time allows for quick removal or installation - A quick switch between manual and automated operation is possible, streamlining workflow - Only two gear wheels are required despite a large transmission ratio, thanks to the combined hoist design - The design utilizes mostly standard parts that can be sourced easily, such as 608RS skate bearings and standard metric bolts Disclaimer: This ventilator is a complex piece of equipment that requires high standards with multiple safety features. Different countries have varying legal minimum requirements and conditions for ventilators, which this device may not meet. Operation of ventilators is reserved for trained and qualified medical personnel only. I am not liable for any damage, accidents, failures, or health consequences resulting from the use of this construction. This design is an experimental concept intended for further development and experimentation purposes only, not a fully functional medical ventilator.
