Abstract:
Objective:To develop an integrated intelligent device of measurement and calibration for cardiopulmonary resuscitator,so as to improve the efficiency and reliability of measurement and calibration of cardiopulmonary resuscitators,and to ensure the safety and effectiveness of rescuing wounded.Methods:This device used modern sensor transmission technique,and adopted a systematically combined design with industrial control measurement and control module.This device could realize simultaneously automatic detection for a series of parameters included depth and frequency of pressure,single breath frequency,moisture volume and so on in the device of measurement and calibration.Results:The measurement and control of the measurement and calibration device of the integrated cardiopulmonary resuscitator are accurate,which average values of pressure depths were respectively(29.8±0.13)mm,(49.3±0.08)mm and(69.89±0.14)when standard values were respectively 30,50,70 mm.The pressure frequencies were respectively(79.30±0.08)times/min,(99.89±0.14)times/min and(119.94±0.24)times/min when standard values were respectively 80,100 and 120 times/min.The moisture volumes were respectively(347.99±2.77)mL,(546.18±1.89)mL and(746.67±2.14)mL when the standard values were respectively 350,550 and 750mL.The above results of this dive are consistent with the results of the standard device,and the errors of depth and frequency of pressure,and moisture volume were respectively±15%,±10%,±20%,which all were within the allowed range.Conclusion:The measurement and calibration device of integrated intelligence of cardiopulmonary resuscitators can complete various detection of related parameters within one pressure cycle of the cardiopulmonary resuscitator.The detection results of the device are highly consistent with those of the standard device,and the detection results are accurate and reliable.
