Design of Portable Automatic Positive Pressure Resuscitator System
In view of the problems of large volume and inconvenient carrying,low safety factor of positive and negative pressure breathing mode,and low automation of manual switching of various functions in the current market,a portable automatic positive pressure resuscitator is developed.Most of the components in the air circuit board container system are adopted,which greatly improves the portability of the system.The pneumatic logic elements are used to form the oscillation circuit to replace the original automatic lung,realizing the full positive pressure of the system and improving the safety factor of the system.The pneumatic logic element is used to sense whether the injured person has spontaneous breathing,and the automatic switching function is based on the condition of the injured person,which improves the degree of automation of the system.
