  • Abstract Tracheobronchial suction is simply categorized into open suction and closed suction. A quite amount of literatures found the closed suction is safer than open suction. Not only the patient ventilation circuit has to be disconnected during the procedure of open suction, resulting in decrease of blood oxygen saturation, but also due to the open characteristics, potential infectious matters from a patient may disseminate to clinical staffs and healthcare givers. On the contrary, there is no need to disconnect the ventilation circuit while using closed suction technique, providing stable blood oxygen saturation, preventing from complications derived from low blood oxygen, as well as maintaining stable oxygen supply and breathing pressure. In addition, the closed system blocks routes of dissemination of respiratory diseases. Among the scientific surveys, it was suggested to use closed suction system as a tool of airway suction.
       This study proceeded in order of three stages. The first stage was gathering information from literatures and customer complaint data, analyzing the questions or concerns on usage of closed suction system, and getting conclusion of what should be improved. The next stage, stage 2, was constructing a 3D model through design schemes establishment which was derived from the concerns collected in stage one. After that, a real prototype was made. The final stage was establishing test programs pursuant to the design in stage 2. 10 subjects were to perform the designated experimental tasks for 5 times in simulated environment. Data from the experiment were collected and statistically analyzed by SPSS software. The quantitative data were analyzed by Independent-Samples t Test, and qualitative data were analyzed by Chi-square. Set p < 0.05 as well as 95% C.V.
    The results of this study were summarized as: there were 5 concerns from users on the usage of present closed suction system: patient non-comfort due to flow of saline or sterile water into him; hypoxia due to slip of catheter into patient; hypoxia due to long-time catheter cleaning; air leakage due to misallocation of catheters; poor efficiency of suction. The author has re-designed a new closed suction system to overcome the 5 concerns stated above, and had it comparatively tested against the present closed suction system. Through the independent Student t-test and Chi-square analysis, the designed closed suction system, revealed significant improvement to the 5 concerns that the present closed suction system suffered. Concerning the safety of patients and users, the improvement of closed suction system, that overcomes the defects of present closed suction system, if possibly being promoted in the hospital, makes benefits especially positive to the safety of patients and users.
