Abstract: Objective To design a portable respirator that can facilitate both cardiopulmonary resuscitation and auxiliary oxygen inhalation.Methods Positive pressure design as well as pneumatically powered and controlled design were adopted for this respirator.Theoretical calculation of key components was carried out.The virtual prototype was established and the structure checked using the three dimensional design software Solidedge.Finally,the prototype was processed,assembled and tested.Results Experimental tests proved that the designed respirator was capable of cardiopulmonary resuscitation and auxiliary oxygen inhalation when oxygen supply pressure reached 3 -5.5 bar.It could achieve the expected technical indicators,such as the oxygen flow rate that was between 10 and 12 L/min.Conclusion The portable oxygen supply respirator has the advantages of a small size,light weight,simple operation,and automatic power supply.It has broad prospects of application.
