To provide medical treatment workers or patients lack of experience in making medical appliance prescriptions prior to a medical treatment or during the medical treatment with a medical treatment continuous condition suiting the patient itself based on medical treatment data accumulated in the past.SOLUTION: A medical server 11, which predicts a medical treatment continuous condition for curing patients having chronic respiratory illness, has: a reception unit 12 that receives patient information including biological information on patients transmitted from users； a selection unit 15 that prepares selected existing patient information data in which medical treatment continuous number-of-days data more than the number of days set in advance for the chronic respiratory illness selected is selected on the basis of existing biological information data on a plurality of existing patients having already undergone the chronic respiratory illness or past patients having undergone the chronic respiratory illness in the past, existing patient information data including existing medical treatment condition data and existing medical treatment continuous number-of-days data, and the patient information received by the reception unit； and an analysis unit 16 that analyses the selected existing patient information data, and selects a prediction medial treatment continuous condition of the patient from an analysis result.SELECTED DRAWING: Figure 1【課題】医療機器処方の経験が少ない医療従事者や患者に、過去に蓄積された治療データをもとにした患者自身に合った治療継続条件を治療前や治療中に提供する。【解決手段】慢性呼吸疾患を有する患者を治療するための治療継続条件を予測する医療用サーバ１１であって、利用者から送信された患者の生体情報を含む患者情報を受信する受信部１２と、既に慢性呼吸疾患の治療を行っている複数の既存患者や過去に慢性呼吸疾患の治療を行った過去患者の既存生体情報データ、既存治療条件データ及び既存治療継続日数データを含む既存患者情報データと、受信部が受信した患者情報と、に基づいて、慢性呼吸疾患ごとにあらかじめ設定した日数以上の治療継続日数データを選別した選別既存患者情報データを作成する選別部１５と、選別既存患者情報データを解析し、解析結果から患者の予測治療継続条件を選出する解析部１６と、を有する。【選択図】図１
