Development and Application of A Precision Sputum Meter
摘要
Abstract
Objective To develop a metering device for precise single measurement of sputum volume,which is applied to clinical observation and provide accurate reference for diagnosis and treatment. Methods This study was conducted between May and September 2015. The precision sputum meter used in this study was developed by our research group in March 2015 (patent number:ZL 201520346561.7). The subjects enrolled in this study were some patients (new born babies, infants,elder children and adults)hospitalized in the ICU,PICU and Neonatal Ward of The People′s Hospital of Guangxi Zhuang Autonomous Region during the period of study. We used precision sputum meter,pure naked - eye observation and sputum meter with the same frequency,to measure the sputum volume of the patients of the above 4 age groups with normal oral and nasal suctioning versus those with endotracheal suctioning during mechanical ventilation (each method of measurement was used 20 times for every age group with normal oral and nasal suctioning versus endotracheal suctioning during mechanical ventilation). In this way,we obtained the data about the accuracy of these 3 methods of measurement. In September 2015,we conducted a survey about the accuracy of precision sputum meter and sputum meter of measurement in 160 nurses who used them using the self - developed questionnaire. All the nurses returned valid questionnaires,suggesting that the response rate of the survey was 100. 0% . The accuracy scores of 2 methods of measurement assessed by the nurses were recorded for making a comparison. Results Precision sputum meter as well as sputum meter has higher overall accuracy than pure naked - eye observation in measuring the sputum volume of the patients aspirated by normal oral and nasal suctioning or by endotracheal suctioning during mechanical ventilation (P < 0. 05). The accuracy of pure naked - eye observation was lower than that of precision sputum meter and sputum meter in respectively measuring the sputum volume of the patients of 4 different age groups aspirated by normal oral and nasal suctioning or by endotracheal suctioning during mechanical ventilation (P < 0. 05). Precision sputum meter had higher scores than sputum meter in the aspects of operability,washability,portability,easy - observation, easy - fixation and cost - effectiveness (P < 0. 05). Conclusion Precision sputum meter is good for clinical application for its accuracy,easy operation and convenience,and helpful for diagnosis and adjustment of treatment.关键词
