With　the　development　of　healthcare　technology　and　medical　standard,　the　demands　of　the　quality　and　efficiency　of　mobile　nursing　are　increased　significantly,　hence　it　is　necessary　to　improve　hospital　nursing　mechanism　dealing　with　massive　tasks.　In　this　paper,　we　develop　an　optimized　mobile　nursing　system　based　on　the　specific　nurse　workflow　analysis　in　obstetrics.　An　efficient　integration　system　framework　is　proposed　combined　with　existing　hospital　common　systems　and　WLAN　network　environment,　which　implements　automatically　execute　data　interaction.　A　combination　model　of　C/S　using　PDA　on　hand　and　B/S　using　PC　working　at　nurse　workstation　is　implemented　which　ensure　the　mobility　and　centrality.　A　lighten　AJAX-SSH2　development　framework　is　used　to　enhance　the　function　expansibility.　The　proposed　system　has　been　applied　in　a　regional　obstetrics　hospital　in　China.　Practical　clinical　application　results　prove　that　the　proposed　system　can　raise　nursing　efficiency　and　reduce　medical　error　rate,　make　it　possible　to　nurses　paying　more　attention　on　patients.　The　healthcare　big　data　collected　by　this　system　has　considerable　value　for　further　research.　©　2016　IEEE.
